FDA Grand Rounds: The comprehensive in vitro proarrhythmia assay (CiPA) initiative

Dear All: 

Per an email received today, there will be an FDA Grand Rounds webcast on 14 Sep 2017 (noon-1p EST) in which FDA unveils a new paradigm for evaluating the cardiac safety of new drugs entitled the Comprehensive in vitro Proarrhythmia Assay (CiPA) initiative. Here is the link to the FDA webpage where you can get further details and register for CE Credit. I provide some of the extended information below my signature.

Context from the email I received: Between 1990 and the early 2000s, multiple drugs were removed from the market because they caused arrhythmias and sudden death.  In response, regulatory guidelines were implemented that have successfully prevented such occurrences by focusing on detecting hERG potassium channel block in cells and QT prolongation on the electrocardiogram.  However, this approach is not very specific because some drugs are flagged as posing a risk and thus can be dropped from development when they are actually safe. A new model, the Comprehensive in vitro Proarrhythmia Assay (CiPA) initiative, aims to be a more accurate and comprehensive, mechanistic-based assessment of drug safety.

My futher notes: This is exciting to see! I don’t follow this area as closely as I should, but the idea that preclinical measures offer a way to improve on the current cumbersome approach to evaluating cardiac risk. This idea appears to have been discussed and endorsed (pending ongoing validation studies; see Cavero 2016, DOI 10.1016/j.vascn.2016.05.012) at a 15 Mar 2017 FDA Advisory Committee meeting. Hence, I suspect that everybody who does drug development will want to know about this.

All best wishes, –jr

Extended information about the Grand Rounds
Title: Developing a Mechanistic Model-Based Approach to Assess Cardiac Safety of New Drugs
Date: Thursday, Sept. 14, 2017
Time: 12:00 p.m. -1:00 p.m. EST
Presented by: David Strauss, MD, PhD; Director, Division of Applied Regulatory Science; FDA’s Center for Drug Evaluation and Research

Per the email, here are 4 things you’ll learn from this webinar:

  1. Why we need a new cardiac safety regulatory assessment model for drugs.
  2. The different technologies being used to inform drug safety, including ion channel assays, in silico models, induced pluripotent stem cells, and biomarkers.
  3. The potential for mechanistic, model-informed approaches to be used more broadly at FDA.
  4. The benefits of research collaborations using public-private partnerships

CDC-FDA webinar: Developing drugs to prevent healthcare-associated infections (30 Aug 2022)

Dear All, A quick note today to call your attention to an upcoming webinar that will be of wide interest. Substantial new details have been added to the online agenda materials for the 30 August 2022 (virtual, 8.30a-5.00p ET) webinar sponsored by CDC and FDA entitled “Drug Development Considerations for the Prevention of Healthcare-Associated Infections.” This is very

US Senate and House / Call for Pull incentives in FY23 budget

Dear All, The US Government is now building its budget for FY23 (Federal Year 2023, really runs 1 Oct 22 to 30 Sep 23). We had proposals from the House for the Department of Health and Human Services (DHHS) budget in late June;  and the proposal from Senate was released on 28 Jul 2022. Each

WHO Vaccine pipeline review; CDC on impact of COVID on AMR

Dear All, WHO continues to crank out those pipeline reviews … now we have one for bacterial vaccines! Go here for the press release and here for the report. The report considers data from 2010 forward and (interestingly) provides data on both active and failed projects. The review identified 94 active preclinical candidates and 61

IDWeek 2022: New pipeline sessions seek presentation of therapeutics and diagnostics!

Dear All: I have learned that the program for IDWeek 2022 will have specific dedicated pipeline sessions for therapeutics and diagnostics. The online details are relatively scant, but my understanding is that the therapeutics of interest for these sessions include antibacterials, antifungals, and non-HIV, non-COVID antiviral agents. There do not appear to be any constraints
