FDA workshop: Animal models to support antibacterial development (5 Mar 2020)

Dear All (moderately long note alert; be sure to note the new list of funding opportunities just below my signature),

FDA have announced a public workshop on 5 Mar 2020 to discuss progress and challenges in the development and advancement of various animal models for serious infection. The Federal Register notice is here and registration is here. The workshop will be webcast and it has these goals:

  • Review the progress and challenges in the development of small and large animal models of serious bacterial infections funded by FDA, BARDA, and NIH.
  • Understand the pharmacokinetic considerations in animal model development.
  • Understand the role that animal models currently play in antibacterial drug development
  • Determine potential priorities for future research and development in this area

As FDA makes clear in their announcement, this workshop builds on a 1 Mar 2017 workshop on this same theme (link to my prior notes). In brief, that prior workshop focused on ways to support development of narrow-spectrum agents for A. baumannii (Abau) and P. aeruginosa (Pae).

The core context is that (i) it is hard to design development programs for drugs focused specifically on these two important but rare organisms and (ii) it is also hard to find ways to support small clinical programs with strong animal model data. Yes, we have examples of using the Animal Rule for biothreat pathogens but Abau and Pae lack the explosive virulence that makes primate models of plague and the like so very compelling. Rather, preclinical models of Pae and Abau have to date required a lot of manipulation of the host and have simply not been very good mimics of human disease.

As a good summary of the difficulties around this issue, I suggest you start your reading with this IDSA-supported white paper (Boucher et al., J Infect Dis 216:228–236, 2017, link). This paper uses the discussion from yet another (!) prior workshop (18-19 Jul 2016, link for even more materials) of a hypothetical Drug X-1 with a spectrum limited to P. aeruginosa. Even with a full day of debate by an active group of discussants. plausible development programs for X-1 were not evident.

This new workshop is thus timely and fits well with ongoing efforts by FDA, NIH, and BARDA to find a way forward by funding work in this space. I do not pretend to have a complete list, but one example is the currently open call (link) from FDA for applications to create rabbit models of ventilator-associated bacterial pneumonia (VAP or VABP, depending on your preferred abbreviation) due to carbapenem-resistant strains of A. baumannii and P. aeruginosa.

So, this should be a very instructive conversation and I look forward to hearing how it builds on the prior debates. If you can’t be there in person, I suggest you plan to attend by webcast!

All best wishes, –jr
