>> Martin Blaser: Welcome to day two of PACCARB seventh public
meeting.
I'm Martin Blaser, chair of the council.
It's my pleasure to welcome everybody to this event.
Today, we'll continue with updates from federal agencies on the year two activities and their
work on the milestones of the National Action Plan.
We'll also hear from our working group co-chairs and council on the work they're been doing
over the past year about incentives.
Then there will be a council discussion and a vote on the report.
And, now I'd like to hand over the microphone to Jomana Musmar the acting designated federal
official to open today's meeting.
Jomana --
>> Jomana Musmar: Thank you, Dr. Blaser.
Good morning everyone, and welcome back to the second day of our public meeting.
The Presidential Advisory Council and Combating Antibiotic Resistant Bacteria, my name is
Jomana Musmar, I am the designated federal officer of the Advisory Council.

made which comment.
Especially during discussion of the report this afternoon.
Please make sure that your microphone is turned off after your comment is made.
And, I will now turn it over to our co-chair, Dr. Lonnie King.
>> Lonnie King: Thanks very much, Jomana.
And, let me add my welcome to all of you and thanks for being with us today.
So, this morning we are going to continue listening to our federal agencies and partners.
Yesterday, they updated us on stewardship and today we'll have them update us, update
what they've done for the last two years in terms of infection -- infection prevention
and the goals two through five.
So, we'll do that for the morning, we'll take a mid-morning break, have lunch, and then
come back and devote our time to our report.
So, to get us started, Michael Craig, do you want to start please?
>> Michael Craig: Sounds good.
So, good morning, I'm Michael Craig.
I'm Senior Advisor for AR coordination and strategy at the Center for Disease Control.
Yesterday, you heard from Dr. Srinivasan about CDC's portfolio for antibiotic stewardship.
Today, I'm going to be talking essentially about the rest of CDC's portfolio for the
prevention of AR infections.
And a couple highlights just to start off -- nope.
So, CDC's work on antibiotic resistance really is going to fall into especially our prevention
portfolio is going to fall into three main buckets.
Detection and response, prevention and containment, and innovation.
And some of the themes that you're going to hear today are really going to be about improved
detection, how that leads to faster response, and how that faster response ultimately means
fewer infections and fewer people getting sick of drug resistant infections, which is
our ultimate goal.
On the laboratory and diagnostic side, I'm going to be highlighting some of the important
work and important investments that are going into improving laboratory detection specifically.
Across our country, at the state level, at the regional level, with the new AR lab network.
How that work is ultimately going to support improved detection, which is, then -- that
detection is then going to the boots on the ground.
The first responders at state public health departments and CDC, so that when new forms
of resistance are identified, they are responded to expeditiously and effectively in a way
that prevents infections from occurring, contains transmission of resistance and hopefully with
the ultimate goal of saving lives.
We'll also touch on some of the other activities that CDC has, our communications and guidance.
Some of this was covered yesterday by Dr. Srinivasan.
We try to out the best science and try to talk about the best science and talk about
how resistance is evolving.
What we're seeing, what are some new things that health care providers or other folks
who are working on resistance need to be aware of, how patients can protect themselves, how
the community can protect themselves.
Arjun a lot on improved antibiotic use, it's in some of the materials we've put out there.
Here you see some of the core elements, which as Dr. Srinivasan noted yesterday, have really
become the basis for a lot of the work that's going on at CMS and the joint commission,
in terms of improving antibiotic use and really standardizing practices across health care.
On our innovation side, we're also going to be touching on what are the gaps in science?
What are the things that need to be improved upon?
And, how can we do better?
How can we look at what's happening in prevention, what's not being prevented and then ultimately
make improvements?
And, then last, but certainly not least, we're going to take all of what we develop in public
health and see how we can contribute to research and development of new diagnostics and ultimately
new drugs and new therapeutics as well.
So, to start off, I'm going to start on the health care side and this chart really talks
about the traditional approach to preventing health care associated infections.
And, as you can see here, there has been tremendous success at preventing health care associated
infections.
Specifically, central line associated blood stream infections, surgical site infections,
catheter associated urinary tract infections, in our country.
This work has really been a combined effort, by CDC, CMS, ARC and OASH.
And, we continue to work toward those goals, to prevent these types of infections.
What I would note though, is that the challenge is that when we introduce antibiotic resistance
and when we address CDIF and we deal with drug resistance, that creates new complexities.
And the traditional approach of improving the practices is in a single health care facility
and in a single hospital, really aren't sufficient.
We have to approach things from a public health perspective.
We have to look at a community, because effectively patients are moving from one health care facility
to another.
They're moving from a nursing home, they're moving from their own home to a long term
acute care, to a hospital and back.
And when they're moving and they're either colonized or infected with the drug resistant
organism, they are taking those pathogens with them and they are potentially spreading
them across the community.
So, we need approach that's a regional approach and we need an approach that looks at this
movement, that looks at the risks across the communities, and that has an infrastructure
in place, both a laboratory, a detection infrastructure.
As well as an infrastructure in the state public health department to be able to respond
to those threats, when they emerge.
And to this end, CDC has been investing in with new resources, capacity in 27 states
and four cities to really aggressively expand this regional approach to antibiotic resistance,
especially at the health care level.
And this has been really critical to making advances and to be standing up an infrastructure
that is going to have long lasting results for our country.
To support this, we have established an AR lab network.
The AR lab network, as you can see here, is comprised of supports for both individual
state health department labs, as well as regional labs that do more sophisticated testing on
par with what CDC does.
We also, this year, are rolling out the first national TB molecular surveillance center.
That new center, which is actually going to be based out of Minnesota -- oh sorry, Michigan,
is going to be sequencing every TB case in the United States.
And, through whole genome sequencing, we actually expect to learn a lot more about the dynamics
of transmission and what we're seeing for TB in this country, with the goal of ultimately
coming up with new ways of preventing its transmission in the U.S.
The rest of the lab network is doing things similar for a variety of other pathogens.
Ultimately, we're trying to improve the detection of new forms of resistance so that the capacity
I described at states to be able to respond to these things, can effectively respond.
I'll go into that in more detail.
So, part of what we're doing here is trying to contain new forms of resistance.
And, we're really approaching over the past two years, coming up with a containment strategy.
And, this slide is really showing you why this is important.
So, Klebsiella pneumoniae carbapenemase KPC is a type of resistance found in CRE and CRE
is the nightmare bacteria.
The one that is resistant to most of our antibiotics, including the most powerful ones, the carbapenems.
What you see here is this form of resistance was very rare in 2001.
And we didn't have infrastructure in place, we didn't have the ability to detect it, we
didn't have the ability to respond to it, and as you see here, because we lack that
infrastructure in the U.S., it marched across our country.
So, it went from something that was terrible and rare to something that was terrible and
endemic.
And this is ultimately what we don't want to happen and this is what we ultimately want
to change, with the investments that we're making in prevention at CDC.
So, the strategy of containment is really looking at what are the rare threats, what
are the new threats that are emerging?
New forms of CRE, MCR1, pan resistant organisms, Candida auris -- which, if folks aren't aware
is a new form of Candida that is extremely resistant and has been spreading across the
globe and we definitely want to avoid it becoming endemic in this country.
And, we really look at the settings, where we have historically seen lots of transmission
and amplification of drug resistance.
Long-term care settings, long term acute care settings, skill nursing facilities.
And we really want to focus on when we identify one of those threats, that we act aggressively
to stop it and contain it and try to make sure the transmission is stopped.
And so, these are maps of what we see today.
So, OXA-48, VIM, IMP; these are all very technical forms of CRE and right now they are rare and
we do not want these maps to become fully blue, like we saw with KPC.
We want to stop them and contain them, where they're at.
C, auris is the same way.
This is something as I noted, we definitely want to avoid it becoming endemic in our health
care facilities, because it will have grave consequences for patients.
And this is where we're at right now and what we really are trying to do with the containment
strategy, is that when one of these cases is identified in the lab network, there is
a robust response by the state health department to be able to stop it, contain it and make
sure that we don't see additional cases.
And, to date, we've had success.
We have seen that, starting in January of this year, we have identified 2000 CRE cases.
About 15 percent of those are new forms of resistance and when we've seen those, we have
triggered a comprehensive response by the state health department.
This year alone, there have been over 40 investigations just since January of this year, there have
been over 40 investigations for drug resistant infections in health care that CDC has helped
consult on.
We have worked to contain very specific outbreaks and have had success for things like C. auris,
where, you know, for example the state of Oklahoma we had an imported case come in that
was identified very quickly, it triggered a very robust response, and we had no onward
transmission in that facility or in the state, whatsoever.
And, that's really what we're going for.
We want these things to be contained, we want to stop the movement of them across the country.
We do not want them to become endemic in the United States.
So, moving on from containment, touching on something that is also an added benefit of
our expansion of laboratory resources, the CDC and FDA AR Isolate Bank.
So, this is taking the isolates that we have identified, either through containment efforts
or from prevention efforts and being able to support industry, diagnostic industry,
therapeutic industry, as well as reference labs to have the best available strains to
be able to make sure that they are testing either new innovations or their existing diagnostics
against what is being seen in our country, in terms of resistance.
This has been in place since July of 2015, and it has been extremely popular and extremely
successful.
It's curated from over 450,000 islets in CDC's collection and today, we've had over 571 unique
customers and 637 orders processed.
And what this ultimately looks like, in terms of this, you can actually see the quote here
from a diagnostic developer.
Part of the reason we did this in partnership with FDA, as that the FDA noted that when
a diagnostic company, especially comes to them with a new diagnostic, they often test
them against a variety of resistant pathogens that they find from private companies and
everyone tests them against different pathogens.
We're trying to provide, and we are providing, a single curated set of islets that the FDA
can direct diagnostic manufacturers to test against the same panel, so that we can actually
better compare diagnostic performance because they're being compared apples to apples, in
terms of their performance.
So, that's one of the added benefits of it, but as you can see here, a lot of other companies
we've worked with, some drug companies and therapeutic companies, as well, and they're
testing new compounds against the emerging forms of resistance, to see if there are opportunities
to create new drugs or therapeutics.
So, other aspects of our innovation here, that I just want to highlight, is that we
do a lot in terms of trying to fill the gaps in knowledge.
That prevention is not stagnant.
We always have to be coming up with new ways of filling our tool kit with new tools to
prevent resistance, because, quite frankly, resistance is evolving and we have to evolve
our prevention portfolio with it.
So, we do a lot of innovation work with academic researchers, with health care providers, and
with other investigators in the area of health care, in the area of agriculture and food,
in the area of the environment, and in the area of community infections, as well.
Really trying to understand how transmission is happening, how it can better be detected
and how it can better be prevented, and, what are the new ways of preventing them.
So, turning more specifically to some of the community aspects of our portfolio.
Really, this is following a lot of the same themes of improving detection, so that we
have faster response, so that fewer people ultimately get sick of various infections.
On the food side, we've talked about this previously that CDC is investing in whole
genome sequencing in every state.
To be able to detect salmonella and other food borne disease outbreaks.
And what this ultimately means is that whole genome sequencing will give us more granular
data, more specific data about resistance and the transmission dynamics.
And this is also happening in concert with expansion of whole genome sequencing that's
happening at FDA for food and whole genome sequencing that's happening at USDA on the
animal side.
Ultimately, we have the goal of trying to work across those agencies to better, to more
rapidly identify food borne disease outbreaks and to stop them.
And as you can see here, we have made tremendous progress over the past couple years in expanding
whole genome sequencing capacity at the state level, with the goal that the salmonella in
our country by 2019, 90-plus percent of it, hopefully even more than that, hopefully 100
percent of it will be tested via whole genome sequencing.
And, again, this is lab capacity for gonorrhea and our ability to not only detect the resistance
that we're seeing, but respond to it.
You can see here, in terms of the yellow states are regional labs that are testing for germ
resistant gonorrhea and our blue states are our rapid response sites that are, when germ
resistant gonorrhea is being identified, they're responding to it and acting very aggressively
to make sure it doesn't spread.
And as you can see, between the then and now, there has been a tremendous increase in our
capacity nationally to test for germ resistant gonorrhea and to be able to identify emerging
trends and we are seeing emerging trends and one thing of note for germ resistant gonorrhea,
specifically is that CDC actually develops the treatment guidelines for germ resistant
gonorrhea.
And so, this data is actually being directly used and analyzed by our CDC subject matter
experts in the GC program, so that they can put out the best possible guidance to clinicians
about the best courses of treatment for what people are seeing in the United States.
Continuing, we also have a variety of things that we're working on actively, on the tuberculosis
side, domestically.
In addition to some things that we're doing on the international side, which I'll touch
on in a minute.
One, very critical piece is that we're looking at the TB medical exam.
Right now, immigrants that come to the U.S. are screened for TB and have to have effectively
a clean bill of health on the TB side before they can come to the U.S.
However, other types of visas, specifically students, skilled workers, long term visitors,
those aren't screened at all for TB before they come to the U.S. Countries, such as Great
Britain, Australia, New Zealand, have all instituted a program to expand their visa
categories that are screened for TB overseas.
It has the benefit of actually identifying TB in those individuals and helping them.
It also has the added benefit of reducing the spread and transmission and importation
of TB into the host country.
And so, we're actually looking at how we can expand that with the state department.
We're also looking at innovations in TB treatment both, right now domestically, but we think
they have global applications.
Trying to see how directly observe therapy, which is the gold standard for TB treatment
right now, can be done via smart phone or through new technologies, to make it less
burdensome on patients and potentially more effective.
We've also established in the U.S. a stockpile of TB drugs.
Over the past few years, we have seen that there have been some interruptions in the
drug supply for TB drugs in the U.S. that have affected treatment and have potentially
prolonged outbreaks or made state public health responses more challenging.
And we've established the TB stockpile to try and mitigate any of that.
I also want to just touch on here, example of some of our global work to combat AR.
Most of the portfolio that we have at CDC is focused domestically, but we know and,
as we have talked about yesterday, that resistance knows no borders and that we have tremendous
amount of work that needs to be done globally, we saw that and heard that at the U.N. General
Assembly.
And we want to be supportive and we want to lead in the U.S. and CDC wants to support
as many countries as possible, to improve their detection of antibiotic resistance and
to prevent those infections, within their countries, to improve their stewardship in
those countries, with the ultimate goal of not only helping those countries, bur of protecting
Americans.
Because we know that these pathogens can and will move globally.
So, here's some examples of some of our work that we're investing in right now.
The first national TB program in China has been set up in the past two years, and we
think has a lot of potential to really address some significant challenges with TB that that
country faces.
We do all of this in partnership with the ministries of health with those countries,
because we know that our expertise is important, but it's even more important that that expertise
be shared with those countries and that those countries be invested in so that they can
do a lot of this work themselves.
We've also done a lot in terms of strengthening and trying to establish programs related to
health care and associated infections than AR surveillance in Vietnam and India and trying
to really get a handle on what resistance is being seen in health care settings there
and what infection control can be put in place, so that we can either mitigate the transmission,
prevent the transmission, contain some of those forms of resistance that we're seeing
there.
And then last, I just want to sort of note, in terms of pre and post, you know that's
been sort of a theme that I'm touching on here.
You know, prior to CARB, prior to the investments that the Congress made in antibiotic resistance
-- it's a dramatic change and this slide is really trying to be instructive of the then
and what the now was.
Ultimately, this goes back to is resistance going to move across our country and is no
one going to act to stop it?
And right now, we are establishing and as I've described, we are putting in place an
infrastructure that will be able to detect new forms of resistance, will be able to respond
and we think, will be able to contain some of these threats.
It's not perfect right now and there's a lot of improvements that can be made.
You know, this is really work that has happened over the past two years and really its work
that's really only happened over the past year, in terms of getting state health departments
invested in and where they need to be.
But it's work that we need to be vigilant about, that we need to continue investing
in, and that we think will have, ultimately, incredibly long-term importance for the future
of our nation's ability to prevent and respond to antibiotic resistant infections.
Thank you.
>> Lonnie King: Michael, thanks very much.
So, we'll continue and by the way, we have a 30-minute question and answer discussion
period after all of our presenters.
So, we'll wait until then, so hold your questions until the end.
So, we're pleased to have colleagues from the FDA.
Bill Flynn who, back from yesterday, and Steven Gitterman.
So, welcome and the floor is yours.
>> William Flynn: Good morning.
Thank you again for the opportunity to update the council.
I'm just going to provide a very few brief updates related to the activities on the veterinary
sector and then I will turn over to Dr. Gitterman.
We certainly have quite a number of activities going on with regard to objectives and goals
two and five and in the interest of time, we'd just like to focus on goal two.
Seems like this isn't advancing.
Here we go.
Two key objectives, that I just want to spend a little -- provide some updates on, which
are important.
First objective, related to expanding capacity of veterinary food safety laboratories, to
provide the capability to anti-microbial susceptibility testing.
And then second, enhancing monitoring both on resistance, sales use, and management practices.
Next slide, please.
So, with regard to expanding laboratory capacity and sampling, FDA does coordinate with Vet-LIRN,
which is the Veterinary Laboratory Investigation and Response Network and there were objectives
within the national plan to expand that program.
Unfortunately, with limited resources, we had difficulty in doing that, but despite
that, we have made some advances, which I just want to highlight here.
So, in 2016 and 2017, we were able to provide sequencing equipment to two of those laboratories,
so there's now a total of four network laboratories that have the capability for whole genome
sequencing and are participating in the whole genome sequencing initiative.
We now have a total of 20 of these Vet-LIRN laboratories that are collaborating to conduct
anti-microbial susceptibility testing on veterinary clinical islets, and as of July 2017, over
850 samples have been tested.
So, while we're not hitting necessarily the goals that we necessarily set out in the action
plan, we are making some progress in this arena.
Just looking at, reflecting on several comments, or recommendations that were in the March
2016 initial assessment by the PACCARB, certainly funding has been an important issue for us
and two recommendations related to objective 2.4, which relates to modern and resistant
sales uses and management practices.
It is the point about making sure that FDA and USDA have sufficient funding for surveillance.
Again, for FDA, we did receive some additional funding in 2015, which has helped us make
some expansion to the NARMS program, which I'll briefly speak to.
But, there's been no additional funding since that time, and, as Dr. McCluskey referenced
yesterday, I think there's some positive movement forward on the USDA side, in terms of on farm
data collection, in terms of surveys moving forward, under the NOMS program.
Next slide, please.
So, certainly, as resources continue to be something that slows progress a bit, we are
continuing to look for opportunities to leverage what resources we currently have and look
for opportunities to collaborate with other agencies, as well as working to take advantage
of public private partnerships.
Next slide, please.
So, I'm going to talk briefly about sort of three areas.
Work that we're doing as far as monitoring resistance trends, second being monitoring
drug sales, and then third, drug usage.
So, as far as monitoring resistance, as I mentioned, we did receive some additional
funding in 2015, the NARMS program, or National Antimicrobial Resistance Monitoring System,
as you know, is a joint effort between FDA, CDC, and USDA.
FDA, CVMs, the key element FDA focuses on, in terms of contributing data to that system
is the retail meat arm of the program.
So, based on the increased funding, we were able to expand, not only the number of samples
collected, but also number of sites in various states that have been enrolled in that program.
So, we have increased the number of retail meat samples collected from 6700 in 2015 up
to over 17,000 in 2017.
We've also increased the number of sites that has been conducting testing on enterococcus
from four to 11 sites and for E.coli from four to nine.
It was mentioned early by Michael Craig, the importance of whole genome sequencing and
the significance of that.
At this time, all salmonella and campylobacter, as well as select enterococci and multi-drug
resistance E.coli are now being subjected to whole genome sequencing, under the NARMS
program and that data is being published in NCEI.
We've also made some enhancements is just how data is being reported out through the
NARMS program.
Really starting with the 2014 reporting year, we have a much enhanced integrative report
that also includes some very exciting interactive data dashboards.
And if you visited that site, I recommend that you do that.
We are working on the 2015 reporting year integrative report and hope to have that out
soon.
Next slide, please.
With regard to monitoring sales data, I briefly mentioned this to the council yesterday, I
think two updates in terms of progress moving forward in this arena.
One is we did finalize a rule in 2016 regarding sort of processes for submitting the process
for drug companies to submit sales data to FDA.
And in doing that, made some enhancements, including the new requirement that when that
data be submitted, that companies report out estimates of the quantity of product sold
based on the major food species that's on the label.
Prior to that, data was provided in a lumped data, essentially, for all species on the
label.
Many products that are marketed or market for multiple species.
So, while these are estimates, we do feel they provide us some assistance in helping
to interpret the overall sales data that's being reported.
Somewhat related to that, more recently, just this past August, we did also publish essentially
a white paper for public comment by seeking input on a possible approach for using what
we're calling a "bio-mast denominator" sort of adjustor and that enables us to look at,
at least what we're proposing here is to use this adjustor as a way to try to take into
account animal populations, when we're looking at overall sales data.
That is now open for public comment, and, you know, we'll consider those comments and
kind of move from there.
But we think that does provide us some help in terms of, again, interpreting sales data
as one element of information that's important to assessing antibiotic use practices.
Next slide, please.
And then, lastly, on monitoring usage, again, sales data has its limitations in that it
doesn't necessarily represent what's actually happening at the farm level.
We do believe that it's very important that we have additional data to augment that, and
we are making some progress in this -- in this arena.
We did fund, utilizing some existing funds in August 2016, cooperative agreements.
Two projects were awarded.
The intent is to pilot methodologies for collecting information on on-farm antibiotic use in cattle,
swine, chickens, and turkeys.
So, there are two projects ongoing now, one focusing on cattle, the other focusing on
swine, chickens, and turkeys.
We're continuing to fund that work, and it's looking very promising, and we're hopeful
as to having some very useful information coming out of those ongoing studies.
And then, secondly, as I also mentioned yesterday, we continue to work very closely with our
colleagues at USDA Center for Epidemiology and Animal Health in terms of sharing information
in terms of what we're doing and the work that's going on through these cooperative
agreements, working with USDA on the survey work that they're doing, and also working
to better understand how best not only to collect this type of information, but also
how to -- how to report it in a way that provides the appropriate context.
So, that's the updates I have, and I will now turn it over to Dr. Gitterman.
Thank you.
>> Steven Gitterman: Thank you.
>> Female Speaker: Are you able to get it to work?
Or is it -- okay, just say, "Next slide."
>> Steven Gitterman: Next slide.
[laughs] Hi.
Thank you, again, for the opportunity to update the committee.
I'll try and move a little quicker.
Next slide.
There's been tremendous progress at the agency, and rather than taking the strategy that Dr.
Flynn took, many of our -- many of the progress crosses a number of objectives, so I'm just
going to approach it as a list.
But within CDRH and antimicrobial drug development, there's been a tremendous amount of progress.
There's been a number of guidance documents for both standard and unmet needs that have
been published.
There's been a series of public meetings.
I know several people around the table have participated in them.
Excuse me.
FDA's working very closely and more active than ever with both the EMA and the PMDA -- that's
the Japanese equivalent of the USFDA -- on recommended trial designs.
People have heard the messages that things need to be more standardized to permit international
development.
There's quite a number of qualified infection disease -- qualified infectious disease products
that have been designated at this point, over, you know, 136 total designations for 71 different
products.
And as everyone's aware, a number of the products that have had -- that have been given designation
are now approved.
There's eight recently approved antimicrobial, antifungal products that have the designation,
and there's been many efforts to revise clinical trial designs to allow more rapid progress
and more streamlined approaches to addressing unmet medical -- unmet medical needs.
Next slide.
Right now, there's a tremendous amount of resources implemented in the 21st Century
Cures Act.
We'll talk about that again, but the section 3044, susceptibility testing criteria, a tremendous
advance, which I'll show a slide later, which I think will substantially reduce the amount
of time to getting updated MIC information to clinicians, and the limited pathway for
antimicrobial, antifungal development.
Again, this was passed late last year, and there's a lot of work in implementing that.
And again, there's work, a lot of work, which I'll talk about very quickly later, on CDRH
and coordinated development of antimicrobial drugs in diagnostic tests.
Next slide.
On device development, we're -- again, it's very, very active.
As people are aware, because we keep mentioning it at different meetings, is the first clearance
of a biomarker test to aid clinicians in antibiotic stewardship and both the initiation and discontinuation
of antibiotic -- of antibiotics.
And people go to scientific meetings or read the press, that's a very, very exciting area
right now.
A lot of development.
There's been new technologies for rapid phenotypic susceptibilities, something I personally didn't
think was going to occur.
And it's very, very encouraging to see that people are working on technologies for phenotypic
susceptibility, some of which are very exciting.
As Dr. Craig mentioned earlier, there's continued support for the FDA/CDC Antimicrobial Resistance
Bank.
One thing Dr. Craig didn't mention is that a big part of the original, I guess, initiation
of the bank, was the fact that a lot of device companies couldn't get these isolates.
They would -- they would have to search everywhere, and we'd say, "You have to have the isolates,"
and they'd have to be beating the bushes.
Through a lot of CDC's efforts and some very excellent cooperation, these panels are now
available which substantially accelerates device development.
And there's been continued development of FDA-ARGOS of having standardized genomic material
that device companies could use.
Next slide.
We have cleared, last year, but late last year, the CRE molecular device for detecting
CREs in stool.
I'm told that's very exciting.
There's support -- and this is particularly exciting -- I've used that word a little too
much -- but for new semantic interoperability standards, and there actually is a contract
with Regenstrief to produce a manual and outreach to doing semantic interoperability.
This is the -- basically, the very straightforward concept that all antimicrobial resistance
tests, all, basically, antimicrobial diagnostics, are coded the same way and reported the same
way such that every laboratory, basically, becomes an active means of communicating information.
And we're very excited about this.
We think this could enable decision support.
Can do real-time epidemiology.
Everybody who's doing -- you know, basically, doing these tests can contribute to an ongoing
database for identification.
And this is also an effort that's been very -- which we're very encouraged -- it's been
very active participation from CDC, NLM, ONC, and other partners, especially industry.
But we do have, actually, a published standard on how device manufacturers can communicate
to laboratories how to code these efforts automatically.
Because we have been very keen on the idea that we're actually reducing work for laboratories,
not making new challenges.
And as people are aware, there's a new breakthrough pathway for devices.
Next slide, please.
There's an FDA draft guidance, you know, addressing delays in making susceptibility tests that
was published last year.
There's final guidance expected shortly, and currently, in coordinated development -- I
forgot the title of the slide -- we have nine current pre-submissions.
We're seeing this as a very, very prominent success.
I don't want to push it too much, but the recent approval of delafloxacin, if I have
this correct, had three AST devices available within a month of the drug approval.
And we're really hoping -- we have a draft guidance out.
We're going to revise it to make it, you know, based on comments we've received, and we really
hope this is going to be a very successful model.
Next slide, please.
Next slide, please.
Ah, thank you.
Just one quick illustration of the -- of the impact of the 21st Century Cures Act.
I'm not going to talk through, but this is the old way.
And the blue boxes are just blocking out some confidential information, although I see one
may not have worked that well.
But basically, the old process where the CLSI changed the break point, then a company had
to come in with a labeling supplement for drugs.
That had to be approved.
Then you first -- device companies could first start considering it.
This is a real example, and this was about a three-year process.
The 21st Century Cures has lopped off basically everything between -- parts of the 21st Century
Cures and Coordinated Development have lopped off the first four arrows.
So we've easily cut, on average, probably a year and a half, if not more, from this
process.
Then we ask questions about the details.
People have to fill them in later, but it's a tremendous advance.
Next slide, please.
And just to -- not to waste -- not to go into too much detail, but this is the example of
the coordinated pathway.
And again, we really hope that we're addressing a lot of what have been concerns expressed
at these meetings and others that companies can actually submit an application, a 510(k),
for a device approval, even before the drug is approved.
And that is going to require good coordination between the drug manufacturer, the device
manufacturer, and FDA.
But we do have in place a process that can actually get these devices out very, very
rapidly.
We do not -- we're tired of hearing that the regulatory process is a burden.
And that should not be the case moving forward.
Thank you very much for the opportunity.
And if there's any questions, I'll be glad to address them subsequently.
>> Lonnie King: Thanks very much, Dr. Flynn, Dr. Gitterman.
So, now I'll turn to CMS.
So, Shari, we're working you pretty hard.
So, thanks for being backup.
>> Shari Ling: [laughs] It's my honor to represent the agency
and report out on CMS activities.
This will be a relatively brief presentation, and I'll try to use this opportunity to also
meet the council's request to talk about the evolution of the implementation -- evolution
and implementation of the quality measurement into payment programs.
Next slide, please.
So, yesterday, I touched briefly on the policy and program levers to set the minimum safety
standards for facilities and the surveillance to -- compliance with those expectations.
I also talked a little bit about quality improvement.
And today, I will present on CMS work that supports goal two, specifically objective
2.2, which is expand and strengthen the national infrastructure for public health surveillance,
data reporting, and providing incentives for timely reporting of antibiotic resistance
and antibiotic use in all healthcare settings.
Today, we'll actually focus using the hospital as an -- as an example, both for the evolution
of a quality measure.
But also please know that our work in adopting quality measures that utilize NHSN as a vehicle
of information reporting spans and expands to other care settings beyond the hospital
in a very consistent way to meet the needs that Michael so eloquently illustrated, the
systems approach.
So if we actually go to the next slide, please.
So -- sorry.
Before we get there, I want to also mention that when we talk about payment for quality,
we have to distinguish pay for reporting, which is paying for a facility to participate
by contributing information or quality measure data into the system, where there is a payment
adjustment in the downward direction, also known as a ding, if quality data are not provided.
So, that is pay for reporting.
In addition, though, the next step would be paying for either attainment or achievement
of specific metrics, and that would be paying for outcomes or value.
So, that is pay for performance, which is the next step beyond pay for reporting.
So, there are several -- there's the Hospital Inpatient Quality Reporting System that appears
on Hospital Compare, all of the -- for public purposes to inform consumers for their care
decisions.
There is also, then, Hospital Value-Based Purchasing.
So, Hospital Value-Based Purchasing, the goals and the intent of the program is to promote
the attainment and improvement towards better clinical outcomes for hospital patients and
also improve the patient experience of care during the hospitalizations and providing
the encouragement to improve and go beyond the minimum safety standards -- that is, beyond
the floor that's set by the COPs.
So, this is about quality and value.
Value-based payment incentives are made based on a hospital's performance -- that is, attainment
of a certain score -- but also that they improve from their baseline.
So, there are two constructs there about what is actually being paid for.
The details of Hospital Compare and also the Hospital Value-Based Purchasing Program are
available on the CMS website, and the Hospital Compare site is provided here.
I will also emphasize that in order for quality measures to be implemented in a value-based
purchasing program, in a hospital VBP, they must appear on Hospital Compare for a full
year or longer.
So, next slide, please.
So, this slide just provides for you a couple of points, illustrates a couple of points.
One is that this is the finalized construct for the fiscal year 2018 Hospital VBP Program.
I called your attention to the safety domain that includes C. diff infections -- that is
facility-wide C. diff infection -- in addition to which, we have two healthcare-associated
infections: catheter-associated urinary tract infections, and central line-associated bloodstream
infections, as well as MRSA.
All of these are actually reported into the National Health Safety Network, so again,
in close collaboration with our CDC colleagues.
These have been proposed and finalized through rulemaking for the fiscal year 2018 payment
year.
I will also call your attention to the domains.
So the domains here, safety is worth one-fourth of the total scoring for this fiscal year's
payment adjustments, equal to clinical care measures that are depicted in blue, efficiency
and cost reduction, as well as person and community engagement, so the patient's experience
of care.
So these are equally weighted.
Again, these quality measures in the safety domain have actually been included on Hospital
Compare since 2015.
So, illustrating that, you know, they were implemented for public reporting purposes,
pay for reporting purposes, first, and then subsequently proposed and adopted through
rulemaking in the Hospital Value-Based Purchasing Program.
So, the measures that you see here have all been NQF indoors.
That means opined upon by a multi-stakeholder entity thought to be -- these concepts were
important to measure, actionable, met test characteristics.
And these are all measures that CDC is a measured steward for.
In addition, the process that is required is that those measures have to be included
in the measures under consideration list, and that list -- the doors open each December.
That list is, then, opined upon by the measure application partnership, which is also implemented
and hosted by the National Quality Forum.
But it goes the next step of the consideration.
Not only are these -- do these measure meet endorsement criteria, but also have accountability
assessed, have been demonstrated that they are useful and feasible to measure.
These all take into account how the measures are used, so not that -- just the measure
construct, but that they are used for payment, with payment implications, is also deliberated.
So, that is part of the process, and this is a reflection -- the display of the final
outcome of that process.
Those measures that are supported for implementation are then proposed through rulemaking and finalized.
That finalization includes consideration of public comment.
And again, CMS has to respond to each and every comment, whether or not just to consider,
or often, those comments provide us -- provide CMS with the opportunity for logical outgrowth.
So, without that opportunity, there's risk and need to often finalize as proposed.
So, the public has an important role to play in the consideration and shaping of all of
these programs, whether IQR or value-based purchasing for hospitals, or the use of quality
measures across all care settings.
Next slide, please.
So you may recall, also, that there is -- so this is a good example of the anatomy of a
quality measure.
This quality measure is a measure that was stewarded by our colleagues at CDC, measure
NQF number 2720, and that is a measure on antibiotic used based on medication administration
data collected by hospitals and reported electronically to the CDC's NHSN.
It was endorsed and met endorsement criteria in 2015 and was then submitted to the Measure
Application Partnership for consideration in 2016.
So, the -- it includes a numerator statement, a denominator statement, and if outcome measures
also will include any risk adjustment that was determined necessary.
The Measure Applications Partnership, in 2016, provided conditional support pending CDC's
recommendation that the measure's ready for use in public reporting and pending resubmission
to the MAP for review of implementation data.
So, that is another update for you.
So, not only are we providing the update of the measures included in VBP for this fiscal
year, but also a status report of where this specific measure is in the process.
Next slide, please.
So, many of you may wonder what happens in this -- in the circumstance of a disaster.
We have seen several in the recent history.
So, in September, CMS actually released a memo granting exemptions to the reporting
under the quality reporting and value-based purchasing programs.
This applies -- these exemptions apply to locations designated by FEMA as major disaster
counties or parishes.
And this actually -- the intent of this is to permit facilities, encourage facilities,
to do the right thing, which is take care of the patients first, focus on disaster recovery,
and also on the -- focusing on the restoration of services.
So, we're continuing to monitor the situation and will provide updates on the exemptions
as time unfolds.
And I will stop there and thank you.
>> Lonnie King: Dr. Ling, thank you very much.
So now we're pleased to have Dr. James Cleeman from AHRQ, and so we're looking forward to
your report.
Thank you.
>> James Cleeman: Thank you very much, Dr. King.
I'm Jim Cleeman.
I'm the Director of the Division of Healthcare-Associated Infections at AHRQ, and I'm delighted to have
this opportunity to provide an update to the council on AHRQ's activities preventing healthcare-associated
infections.
In the area of HAI prevention, AHRQ's activities span the spectrum from research through implementation.
AHRQ supports research to develop improved methods of preventing HAIs and improve the
safety of healthcare -- these studies tell us what to do -- supports research to develop
effective implementation strategies for HAI prevention, a branch of implementation science
-- studies that tell us how to do it -- then translates the research findings into tools
for implementing HAI prevention, and finally, promotes implementation of HAI prevention
with effective methods, strategies, and tools from the first three steps.
Next slide, please.
With respect to HAI prevention research, AHRQ renewed its funding opportunity announcements
in September of 2016.
There was an announcement for large research projects, R01, and large demonstration and
dissemination projects, R18.
And these announcements highlight the intimate connection between HAI prevention and CARB.
We're fond of saying that every HAI prevented is an episode of antibiotic use avoided, a
clear contribution to stewardship.
And in addition, every HAI prevented slows the development of resistance.
The announcements cover applications in all settings: acute care, long-term care, and
ambulatory care.
And they identify broad areas of research interests that include the efficacy and effectiveness
of preventive interventions and relevant epidemiological aspects including the assessment of risk factors
for HAIs and sources of antibiotic-resistant HAIs.
Next slide, please.
Thought I'd give you a couple of examples of currently-funded research in HAI prevention.
You see the first is in nursing homes and the second in households, and this is intended
to signal that AHRQ is certainly funding research in the hospital arena, but beyond the hospitals
in long-term care and in ambulatory care, including even the household.
Project Protect is examining universal decolonization to reduce infections with multi-drug resistant
organisms in nursing homes.
Decolonization is with chlorhexidine body wash and nasal ionophore.
And this is a very interesting study, because the PI of this effort is also the PI of a
suite of four decolonization studies.
The first was the landmark REDUCE MRSA study that showed the effectiveness of universal
decolonization for preventing MRSA transmission in ICUs, hospital intensive care units.
The second was in hospital non-ICUs, wards.
The third, in decolonizing patients upon their discharge from hospital.
And now this one, universal decolonization in nursing homes.
And the study has collected baseline data on the prevalence of MDRO colonization.
These data will be released at ID Week.
So, stay tuned.
They're very interesting, and they are beginning the decolonization protocol in the intervention
arm.
The second study is looking at the integration of personal and household environmental hygiene
measures to prevent MRSA.
The personal decolonization is with chlorhexidine and nasal mupirocin, and the household approach
is to clean the environmental surfaces.
And in addition, AHRQ is funding studies to prevent C. diff transmission and infection
as well.
Next slide, please.
Some examples of the implementation research for preventing HAIs.
The first is a study that's looking at the implementation of chlorhexidine bathing to
reduce HAIs in non-ICUs.
This is using a systems engineering approach that focuses on how various aspects of systems
interact to influence patient safety.
This study is going to produce a toolkit to help other institutions succeed in their efforts
to implement chlorhexidine bathing in their patients.
And the second example is Project SMART, which is looking at the implementation of management
strategies to reduce HAIs.
The PI previously identified several management strategies that enhance HAI prevention.
These include explicit goal setting, inter-professional collaboration, and meaningful use of data.
And this study will culminate in the development of a management practices toolkit for HAI
reduction.
So, you see, in a sense, toolkits from HAI research studies exemplify AHRQ's commitment
to translate the knowledge from research into tools for broad use as has been recommended
by PACCARB.
Next slide, please.
In the air of promoting -- in the area of promoting implementation of HAI prevention,
AHRQ's strong suit is the Comprehensive Unit-based Safety Program, or CUSP.
CUSP is a proven method for preventing HAIs.
It was developed at Johns Hopkins with AHRQ's support, and Dr. Cosgrove has been significantly
involved in the CUSP activities at Hopkins.
CUSP combines improvement in safety culture, teamwork, and communication together with
a checklist of proven practices for preventing the HAI in question.
This combination of behavioral elements in the first set -- safety culture, teamwork,
and communication -- with the clinical elements in the second -- checklist of proven practices
-- creates a powerful tool for accelerating the adoption of evidence-based practices to
prevent HAIs.
Next slide, please.
AHRQ has mounted a set of CUSP implementation projects over the last few years.
Their first was CUSP for central line-associated bloodstream infections, or CLABSI, and then
after that, for catheter-associated urinary tract infections in hospitals, CAUTI, and
then for safe surgery, both in in-patient and ambulatory settings for mechanically-ventilated
patients, for CAUTI in long-term care, for persistently elevated CLABSI and CAUTI rates
in ICUs, and for improving surgical care and recovery.
And I'll say a little more about the last three of these.
Next slide, please.
The CUSP for CAUTI in long-term care project was completed in September 2016, a nationwide
project that achieved a 54 percent reduction -- a highly significant reduction -- in CAUTI
rates in over 400 nursing homes around the country.
And the project produced a toolkit to reduce CAUTI in long-term care facilities that was
released in March 2017, and this toolkit assists other nursing homes to achieve the success
that was seen in this project.
Next slide, please.
With respect to PACCARB's recommendations, this project exemplifies several of them,
coordination with other agencies.
CDC and CMS staff served on the technical expert panel that guided implementation of
the project, and CMS and CDC staff are involved in dissemination of the toolkit as well.
And this project had significant partnerships.
The American Hospital Association's HRET, or Health Research and Educational Trust,
led the conduct of the study together with APIC, the Association of Professionals in
Infection Control and Epidemiology; the Baylor College of Medicine; the Society of Hospital
Medicine; the University of Michigan; and state nursing home associations.
And these partnerships greatly strengthened the expertise and effectiveness of the project.
Next slide, please.
Another project is the CUSP for persistently elevated CLABSI and CAUTI rates in ICUs.
This is a follow-up to nationwide CLABSI and CAUTI projects that AHRQ has previously mounted.
The nationwide CLABSI project produced a 41 percent reduction in the rate of CLABSI, but
not all of the ICUs that participated achieved the same success.
And the nationwide CAUTI project produced a 30 percent reduction in over 700 non-ICUs,
but the ICUs did not reduce their CAUTI rates significantly.
And so, AHRQ felt duty-bound to go back and help ICUs do better in their -- with their
persistently elevated CLABSI and CAUTI rates.
The study has -- the project has completed recruitment of over 300 ICUs across four HHS
regions, has tailored the CUSP interventions to ICUs with persistently elevated rates -- this
begins with an assessment of the ICU's gaps and needs, and then tailors tools and training
to meet those gaps -- has established a project infrastructure using state hospital associations
as coordinating entities, and implementation of CUSP interventions are currently ongoing.
And we are now poised to expand the reach of this project from four regions to nationwide
coverage, and this will happen in the next several weeks.
Next slide, please.
Exemplifying several PACCARB recommendations, coordination with other agencies, this project
has relied on CDC and CMS.
They've been instrumental in identifying ICUs eligible for recruitment into the project.
NHSN data are bound by confidentiality requirements, so they cannot be shared on the level of individual
ICUs, shared with AHRQ, and so CDC has identified ICUs that have elevated CLABSI and CAUTI rates,
and CMS has identified those that are participating in their quality improvement projects.
CDC and CMS staff serve on the technical expert panel that guides implementation of the project.
And significant partnerships have included HRET conducting the lead, the American Nurses
Association, APIC, the Michigan Health and Hospitals Association, the Society for Critical
Care Medicine, the Society of Hospital Medicine, University of Michigan, and state hospital
associations.
And again, this strengthens the expertise and effectiveness of the project.
Next slide, please.
And a third project currently underway is the CUSP for improving surgical care and recovery.
This is a five-year project launched in September of 2016.
It is promoting the implementation of evidence-based practices to enhance recovery, improve outcomes,
and reduce complications including the reduction of surgical site infections and catheter-associated
urinary tract infections.
And some examples of evidence-based practices that are being promoted include state-of-the-art
analgesia with reduced use of opioids, avoidance of prolonged periods of fasting, and early
mobility.
The project is currently recruiting for the first cohort on colorectal surgery.
Recruited 150 hospitals thus far, which is pretty good, considering that 100 hospitals
was our target.
There's a lot of enthusiasm for this kind of approach, and many more hospitals are waiting
to sign up.
Future cohorts are planned for other forms of surgery, including orthopedic, gynecologic,
emergency general, and bariatric surgery.
Next slide, please.
Exemplifying PACCARB recommendations in this project, coordination with other agencies,
CDC and CMS staff again serve on the technical expert panel that guides implementation of
the project.
And the significant partnerships here are with Johns Hopkins University that is leading
the project with its expertise in CUSP and in enhanced recovery.
The American College of Surgeons, that knows a bit -- something or other about surgical
practices and about enhanced recovery, and Westat, that has significant data capabilities.
And finally -- next slide, please -- AHRQ has released new CUSP implementation toolkits:
a toolkit to improve safety in ambulatory surgery centers, that has tailored the implementation
of practices to improve safety in ambulatory surgery centers including the surgical safety
checklist, so that these approaches, these practices, are not simply borrowed from the
hospital setting, but are adapted to be useful specifically in ASCs; a toolkit to improve
safety for mechanically-ventilated patients that incorporates the project's bundle of
evidence-based interventions.
These interventions include low tidal volume ventilation, trials of reduced sedation and
weaning from the ventilator, and early mobility.
And finally, the toolkit for safe surgery in the inpatient setting, which is the product
of a project that reduced surgical site infections by 25 to 40 percent, and the release of this
is planned for later this year.
Next slide, please.
So, we return to the core slide which shows AHRQ's HAI prevention program spanning the
spectrum from research through implementation.
AHRQ is committed to helping the field generate new knowledge for preventing HAIs and translating
that knowledge into action, into the adoption of more effective practices for preventing
HAIs and improving the safety of healthcare.
Thank you for the opportunity to address the council.
>> Lonnie King: Dr. Cleeman, thank you very much.
Appreciate it.
So, we have one final presentation this morning before break, and we're going to turn to Dr.
Jane Knisely from NIH.
Dr. Knisely.
>> Jane Knisely: Good morning.
Thank you for the opportunity to present NIH's work on the CARB National Action Plan.
We play roles in goals two through five, and I've kind of broken those out as I go through
the talk.
Next slide, please.
So, just to orient everyone of who NIH is and who NIAID is, our mission statements are
here on the slide.
You can read them for yourself.
NIAID is part of NIH, and we are one of 27 institutes and centers.
We are the second largest.
And the focus of the division that I work in is on microbiology and infectious diseases.
We're responsible for all infectious diseases other than HIV/AIDS, so it's a big mandate.
And the budget of the NIH is divided -- it's about 10 percent is spent on research intramurally,
so we have scientists working on the NIH campus as well as through other facilities throughout
the country.
And the rest of the budget, most of it goes out the door to grants and contracts to fund
work throughout the country and around the world.
Next slide, please.
So, on the left, you see a photo of one of our guiding documents here, the National Action
Plan, which you're all very familiar with.
On the right, you see the cover of a document that NIAID put together in 2014 that outlines
our antibacterial resistance research strategy.
And what this document emphasizes is that we take a comprehensive approach to addressing
this topic by focusing on basic research, translational research and product development,
and clinical research.
And we do always have an eye towards the development of better ways to diagnose, prevent, and treat
antibacterial-resistant infections through all the work that we do.
In this document, you will also find some areas for enhanced emphasis that we identified.
So this is a few years old now, but we have, I think, made good on putting money where
our mouth is and stimulating work in those areas.
And so, that includes things like non-traditional therapeutics -- so trying to move a little
bit away from small molecule therapeutics, although they're still very important, but
to explore some other new types of therapeutic approaches that are coming on the horizon
-- and an enhanced emphasis on diagnostic technologies, because we view it as really
a critical component to addressing many aspects of this problem, as well as enhanced studies
to optimize how to use the drugs that we have.
So, the existing arsenal of drugs that we have, we need to make the best of them, because
we won't have them forever.
And so we have a number of studies to address that, which I'll talk about a little bit more
on future slides.
Next slide, please.
So, we do have just a little piece of goal two.
Surveillance is not really our area, but I think in objective 2.1, we are playing a collaborative
role here and bringing some of the technologies that we support and some of the infrastructure
that we have to enhance some of the collaborations that are going on.
So, the CDC and FDA Isolate Bank was already mentioned, and NIH is also a partner in that
effort and has provided sequencing services for some of the isolates that have been identified.
This is just part of NIAID's genomic sequencing program which has sequenced over 3,000 bacterial
genomes since 2012.
And all of our genomic data is rapidly released to the public through deposition and NCBI
databases, which is housed at the National Library of Medicine, which is another of NIH's
institutes and centers.
Also housed at NLM is the NIH National Database of Resistant Pathogens, which includes data
on over 130,000 pathogen isolates and includes genome sequencing data and drug susceptibility
phenotypic data when it's available.
And also on this slide, a couple of other technology services that we provide.
We have bioinformatic services.
One is referred to as PATRIC.
That's the bacterial one that we house.
And that group is responsible for developing bioinformatic tools, and they can also assist
researchers with analyzing all of the data that are coming out of these new technologies.
So, that is a resource for the community, along with genomic sequencing.
We have the capacity to sequence collections of isolates kind of in an on-demand fashion
for people in the community, free of charge.
And we also have structure determinations.
So these are things that aren't captured on other slides, so I thought I would mention
them here.
Next slide, please.
So moving on to objective three, which is the -- or, the goal focused on diagnostics.
We've done a lot of -- we have many programs where investigator-initiated projects for
diagnostic development can come in.
So, our small business grant programs, investigator-initiated R01s, things of that nature.
But we've also issued a lot of targeted funding opportunities, and I've just listed a few
here that have come out in the past few years that are really focused on the goals laid
out in the CARB National Action Plan.
So, the one from FY 15 -- and there's more information about all of these available online
-- partnerships for diagnostics to address antimicrobial resistance of select bacterial
pathogens.
This was really focused on diagnosis of infections in healthcare-associated settings, and it
brought in some really interesting technologies that are progressing really well, and it's
exciting to see.
The one for FY 18 is actually currently on the street.
So you know, for any investigators out there, feel free to check it out, submit an application.
Partnerships for the development of clinically-useful diagnostics for antimicrobial-resistant bacteria.
And the focus of this one is phenotypic susceptibility testing.
And so, we've heard that that is -- that is a gap, and so we're trying to address that
gap through a targeted funding opportunity.
And then also on this slide, a line -- just a single line devoted to what is actually
a pretty big commitment.
This is a collaboration with BARDA, an antibacterial resistance diagnostics challenge competition.
It's a new way of doing things that NIH hasn't really done before.
And so this is a phased challenge competition.
Total $20 million pot, some smaller amounts dispersed at different steps along the way
and then a bigger pot at the end.
So earlier this year, 10 semifinalists received $50,000 each for prototype development.
The focus of the projects is either on rapid determination of -- or rapid discrimination
between viral and bacterial infections or rapid determination of antibiotic susceptibility
tests.
And the focus is also on point of care tests, so things that are going to be maximally useful
in the clinical setting.
The semifinalists are a mix of academic and companies, and there's a diversity of approaches,
and three of those 10 received previous NIAID support for their technologies.
The next step is that they will submit prototypes and analytical data in September of next year,
and then up to 10 finalists will be selected, also next year.
And then, the third phase is the evaluation of those prototypes in two independent CLIA-certified
laboratories.
And then, the finalists will be -- or the winners will be announced in 2020.
So that's the prize competition.
Next slide, please.
The Antibacterial Resistance Leadership Group is a program that we have that spans -- it's
a clinical focused program, but it spans both diagnostics and drug development and drug
optimization studies.
So, I'll mention it again later.
This is some of their diagnostics work.
They've really hit diagnostics very hard, and I think it's promising to see some of
the work that they're doing.
They have a project that is focused on host-based signatures to distinguish viral from bacterial
respiratory infections.
They have some resources for the community, including a virtual viral repository where
different members from this group of clinician investigators have clinical isolates with
associated metadata.
They're stored in their labs in their freezers.
They have an online catalog where people can go and request those isolates for studies
on drugs, on diagnostics, whatever.
So, it's a complement to the isolate bank that's been mentioned a few times.
They also have the capability to collect clinical specimens to aid diagnostics development.
So, this is something they've been able to do a number of times now for a couple of companies.
And they are working on a really novel idea of a master protocol for validation of multiple
diagnostics simultaneously.
So, for the same clinical syndrome, can you use the same patients to validate multiple
tests at the same time?
And it was logistically very challenging to set the first one of these studies up, but
it is up and running and rolling and actually going very smoothly.
So that's a very exciting development.
And they are about to launch a clinical trial that's sort of meant to be a definitive trial
for the United States on using procalcitonin levels to identify community-acquired pneumonia
patients who will not benefit from antibiotics -- randomized, controlled placebo trial.
Next slide, please.
So these are all of our responsibilities in Goal 4.
They get a little tangled from here on out, so these are the objectives.
And next slide, I'll just kind of tell you broadly about the things that we are doing.
So, again, for CARB goal four, this is the development of antibacterial and vaccines.
And we have, once again, issued quite a few different funding opportunities for antibacterial
therapeutics since 2015.
And that includes things that are a little bit more basic, like our new systems biology
centers, things that are a little bit more translational, like our partnerships programs
on non-traditional therapeutics and host-targeted therapeutics, and also clinical research.
So, some of the work that ARLG is doing, some of the things going on in some of our other
centers that I'll mention.
We've also had three targeted funding opportunities for antimicrobial-resistant vaccines since
2015.
One is focused specifically on gram-negative bacteria.
One is focused on TB, and then one is part of a bigger initiative, but includes vaccines
on resistant pathogens on the CDC threat list.
All of this is supported by preclinical services and clinical trials networks, which I'll talk
a little more about.
And we also conduct workshops on targeted topics to help bring groups together to discuss
challenges and gaps in the field and to really help guide us when we're trying to put together
kind of where to target our funding next.
Next slide, please.
I did just want to give one example, because it's a lot of, you know, we did an RFA here,
we did an RFA there.
But here's an example of kind of how our different funding mechanisms can work in concert to
produce something pretty cool.
So we have funded, for many years, an investigator called Andrew Myers who's at Harvard University.
He was working on -- he's a chemist.
He was working on synthesis of novel tetracyclines, so complete synthesis of tetracyclines.
And you know, he was going on, he was synthesizing these things and doing really well, and ended
up founding a company that's called Tetraphase Pharmaceuticals.
And then, at a certain point in time, his grant came in for renewal, and the study section
said, "Well, tetracyclines.
These are really old drugs.
This is not innovative, you know.
We're not going to support this."
We actually were able to sort of rescue that one from the dust bin and say, "No, actually,
this is really valuable," and were able to fund it through a selective pay to keep that
-- to keep that work going.
We have very few slots, but we can do it every now and then.
So, the sort of more basic work was funded through grant support.
He then -- that company then went on to receive grant and contract support for preclinical
development of some of their candidates, and then some of their candidates have moved on
to BARDA and have actually completed phase three clinical trials.
So, it's a really cool example of how support throughout the development enterprise can
work in concert.
Next slide, please.
This is just a depiction of our preclinical services.
This is a suite of services that we have available to researchers, free of charge.
We will provide data and tools and technologies.
We can do things like in vitro assessments of antimicrobial activity, MICs, MIC90s, things
like that.
We have interventional agents contracts that can do pharmacokinetics and toxicology studies.
Can also do chemistry manufacturing and control.
We can do GMP manufacturing.
We can do testing of -- for both drugs and vaccines.
And we also have animal model capabilities so we can establish new animal models on demand
to help provide data that companies need to move forward.
Next, please.
In terms of our clinical programs, so the different types of programs are listed on
the left, and then the -- sort of the buckets of studies that they conduct are on the right.
The targeted clinical trials is a program that started about a decade ago and was initially
a series of solicitations focused on addressing questions like dose, duration, and how to
administer the drugs that we currently have to optimize them and reduce the risk of antimicrobial
resistance.
And this came up a little bit yesterday.
So, a couple of them have finished now, and, well, yes, most of the studies -- most of
the clinical trials that have been done looking at short versus long course have shown that
the short course is equally good.
Actually, in our acute otitis media trial, they found that it's -- that the short course
is not quite as good, clinically.
And so, this is -- this is why we need to do the experiments.
So, there are some areas where it's absolutely fine, and then there are others where the
data say, not so fast.
The Antibacterial Resistance Leadership Group is picking up on some of those studies.
They're doing one in pediatric CAP.
They're doing, also, optimization and PK/PD studies, and we also have a couple of other
things where we can support companies who come in and need a phase one trial or other
types of studies, as well as the STICTG, which can do gonorrhea trials.
Next slide, please.
I'm going to skip this one, because I think BARDA will cover it.
Next.
And just the last is our international activities.
Primarily, what we do here is about communication and collaboration with our counterparts in
other countries.
And much of it is driven by our investigators at the scientific level, and that's the way
we like to have it.
But what has been very useful to us is the Transatlantic Task Force on Antimicrobial
Resistance, where we have gotten to know our counterparts in the European Union and have
been able to align some clinical trials to help make them the most informative that they
can be.
And we've also done some workshops and presentations with them as well.
And that's all.
Thank you very much.
>> Lonnie King: Dr. Knisely, thank you very much.
So I want to thank all of our presenters this morning.
Great information.
You're very succinct and very impressive, so thank you for what you're doing.
So we're going to take a 10-minute break right now.
Get coffee in hand, and we have a lot more to hear.
So we'll welcome you back about 10:40.
Thank you.
>> Martin Blaser: Panel members, write down your questions so
we don't forget.
Thank you.
