(Another!) FDA trial design workshop: Complex innovative designs

Dear All:

Adding to the 19 Mar 2018 (Designs for Rare Diseases) and 16 Apr 2018 (Inclusion/Exclusion criteria) workshops already announced (see list below), FDA has now announced a 20 Mar 2018 workshop on complex innovative designs (CID) in clinical drug trials. From the Federal Register notice, we are told that the workshop seeks to (1) facilitate discussion and information sharing about the use of CID in drug development and regulatory decision making and (2) obtain input from stakeholders about a CID pilot program. Ideas to be discussed include complex adaptive designs, use of external/historical control subjects, Bayesian designs, master protocols, clinical trial simulations, and the proposed CID pilot program.

Why is this relevant to those of us working on new approaches to antimicrobial resistance (AMR)? Although AMR does not appear in the titles of any of these workshops, some of the ideas could be (or could become) very relevant for the AMR community.

In particular, the mathematics of rare events make it hard to develop narrow-spectrum agents outside of a few special situations. As non-traditional alternative therapies are often narrow-spectrum (e.g., most monoclonal antibody approaches), we simply must find ways forward lest we never develop such products. 

We’ve had several public discussions on this problem (see this note for further details) and we’re definitely not done with the conversation. As the ideas to be discussed in the upcoming workshops might help us with trial designs for narrow-spectrum products, I’m delighted to see them on the calendar! Also, the mention of a pilot program for complex innovative designs is new and of interest. 

All best wishes, –jr

Japan Pulls for Pandemic Preparedness: Nikkei FT Conference

Dear All, As we discussed in the 5 Nov 2023 “Pulling for Pandemic Preparedness” newsletter, AMR is a global threat: resistance in one part of the world can suddenly appear in your hospital. As an example of that sort of threat, Jason Gale’s 30 Oct 2023 newsletter entitled “Untreatable Typhoid Should Make You Worry About Poop”

Pulling for Pandemic Preparedness

Dear All, This evening I’d like to bring together several relatively recent reports and note how all of them focus in one way or another on Pulling for Pandemic Preparedness … perhaps we can call this the Rule of 3 Ps. And as an aside, I’ll note that I learned the Rule of 4 Ps

PACE: A new £30m fund for AMR innovation

Dear All, Exciting additional news merits two newsletters in one day! I’ll keep it brief and quote directly from the website: “Innovate UK, LifeArc, and Medicines Discovery Catapult (MDC) have joined forces to create PACE (Pathways to Antimicrobial Clinical Efficacy), a £30 million initiative supporting early-stage innovation against antimicrobial resistance (AMR) to save lives.
