Commissioner Gottleib (New FDA initiatives, need for Pull incentives) + updated Pew pipeline analyses

Dear All: It was a HUGE day at the Pew Charitable Trusts today!

First, Commissioner Scott Gottleib gave a superb and very exciting speech. You can either read or listen to the entire speech. There is also a panel discussion after his talk that is worth replaying. Here are some highlights from Commissioner Gottleib’s talk:

  • FDA is working to coordinate all its AMR efforts and part of this is a new integrated website that is effectively a one-stop shop for all FDA AMR-related activities. On this website you can read about …
    • FDA’s new 5-year plan for stewardship in veterinary settings
    • FDA’s public RFI (Request for Information) on development of new antibacterial drugs active against MDR bacteria
    • FDA’s specific focus on 4 topics:
      • Efficient product development
      • Support for antimicrobial stewardship
      • Collecting data on antimicrobial resistance
      • Development of new regulatory tools
    • And much more … you’ll need to look through the entire webpage to understand its impressive scope.
  • The RFI (Request for Information) on development of new antibacterial drugs active against MDR bacteria is especially noteworthy and you should consider submitting your thoughts. FDA are interested in suggestions for research in 5 areas:
    1. Evaluate potential innovations in clinical trial design for new antibacterial drugs such as enrollment strategies, data collection streamlining, drug development tools,clinical endpoints, and new statistical analytic approaches.
    2. Advance the science of in vitro, animal model, and/or pharmacokinetic studies to facilitate antibacterial drug development, including studies focused on drug development for special populations such as patients with unmet need, children and patients with renal or hepatic dysfunction.
    3. Evaluate the use of rapid diagnostic tests in clinical trials for new antibacterial drugs to enrich enrollment of patients with the condition of interest.
    4. Advance the science of antibacterial drug susceptibility evaluation.
    5. Evaluate potential endpoints in clinical trials in the area of unmet medical need.
  • In his comments, Commissioner Gottleib calls for both Push and Pull incentives:
    • His discussions of Pull incentives were completely on target — he clearly lays out the background issues and rationale.
    • He indicated that FDA and CMS are working together to further develop these ideas.
    • His initial focus is on some form of subscription model to ensure access to new drugs while providing enough of a foundation for a guaranteed market to encourage ongoing work.
    • During the Q&A, he very clearly articulated the principles of paying for new antibiotics using the equivalent of market-entry rewards. 
  • I think it is incredibly powerful to have such a clear call for Pull incentives from the FDA
    • Although it is easy to criticize any given set of Pull incentives, the challenge is to propose an alternative that can actually be implemented.
    • The attractive thing to my ear about the ideas from Dr. Gottleib is that the ideas align well with the principles elucidated by DRIVE-AB for solutions that could actually be effectively implemented.
    • And the core advice to those of us doing development is to focus on innovation. I don’t think it will be possible for all new products to be part of the early wave of Pull incentives — successful products will offer something special or distinctive.

Second, Pew Trusts’ antibiotic resistance projecthas updated its pipeline reviews of both the 42 small molecules as well as the 30 non-traditional products (antibodies, vaccines, etc.) currently in clinical development. It’s exciting to see that the pipeline includes a reasonable number of products for Gram-negative bacteria (12) of which at least a few are truly novel products (1 small molecule, 5 non-traditional products). At the same time, these numbers are tiny by comparison to the magnitude of the public threat, as well as being dwarfed by the number of products in development in other areas (e.g., oncology).

On the theme of non-traditional antibiotics, the panel discussion that follows Dr. Gottlieb’s talk is really worth your time. The key messages firmly reinforce those from the 21-22 Aug 2018 FDA workshop on non-traditional products: These products can usually be developed using existing tools and trial designs and those approaches should be followed if at all possible.

Wow! A big day! There’s a lot to review here … you should set aside a couple of hours for a detailed look. And, you’ll want to seriously consider responding to the RFI on new antibacterial drugs for MDR bacteria.

Good work by Team Pew and by FDA! All best wishes, –jr

How economists (and Finance Ministers) think…

Dear All, Anthony McDonnell and his colleagues at CGD (Center for Global Development) have just released a truly lovely paper on the economics of antibiotic resistance. What makes this one special is that the paper dissects the problem of AMR through an economist’s spectacles in a way that is very accessible to the non-expert. You

The road to UNGA 2024 is paved with … reports!

Dear All, We’re now well into the run-up to the HLM (High-Level Meeting) on AMR during UNGA 2024 (the UN General Assembly, September 2024, see the 15 Apr 2023 newsletter for details). In preparation, reports providing data to support policy and decision-making are continuing to appear. Today, for example, GCOA and IDSA released their report entitled “2024

Leaving the lab: The decline in AMR R&D professionals

Dear All, The AMR Industry Alliance has today released a fascinating and disturbing report. Entitled “Leaving the Lab: Tracking the Decline in AMR R&D Professionals” (press release, report itself), its key message of “Researchers Are Leaving the AMR Field – Even as the Threat Rapidly Grows” is illustrated vividly by the report’s graphics. I’m going
