Weekend reading: HABP-VABP study design; Overview of AMR initiatives

Dear All:

Two papers (one with an editorial) that are worth your time.

First, we have publication of the long-awaited FNIH (Foundations for the NIH) paper on trial designs for studies of HABP-VABP (Hospital-Associated Bacterial Pneumonia and Ventilator-Associated Pneumonia). The paper also comes with an editorial:

  • Talbot, G. H., A. Das, S. Cush, A. Dane, M. Wible, R. Echols, A. Torres, S. Cammarata, J. H. Rex, J. H. Powers, T. Fleming, J. Loutit, S. Hoffmann and H. V. P. T. Foundation for the National Institutes of Health Biomarkers Consortium (2019). “Evidence-Based Study Design for Hospital-Acquired Bacterial Pneumonia and Ventilator-Associated Bacterial Pneumonia.” The Journal of Infectious Diseases: jiy578-jiy578. (link)
  • Eby, J. C. (2018). “Exploring Standard Endpoints for Clinical Trials of Pneumonia Therapy.” The Journal of Infectious Diseases: jiy708-jiy708. (link)

This paper is one to read in detail. Two key messages to take away:

  1. Non-ventilated HABP is meaningfully different from ventilated HABP and from VABP. You can study the latter two together but non-ventilated HABP needs its own stratum or study.
  2. All-cause mortality (ACM) is a clear and useful endpoint but modern studies may find that ACM is low enough (< 15%) that the standard non-inferiority margin of 10% is not really acceptable. In this case, event rates can be usefully increased with an ACM+ (“mortality plus”) endpoint in which markers of toxic/septic shock are counted as endpoints.

The community owes a great debt to George Talbot for leading the charge on this as well as on the prior FNIH work on endpoints for skin and CABP. If you’ve not looked at them recently, now would be a good time to re-review the prior papers:

  • Talbot, G. H., J. H. Powers, T. R. Fleming, J. A. Siuciak, J. Bradley and H. Boucher (2012). “Progress on developing endpoints for registrational clinical trials of community-acquired bacterial pneumonia and acute bacterial skin and skin structure infections: Update from the Biomarkers Consortium of the Foundation for the National Institutes of Health.” Clin Infect Dis 55(8): 1114-1121. (link)
  • Talbot, G. H., J. H. Powers and S. C. Hoffmann (2016). “Developing Outcomes Assessments as Endpoints for Registrational Clinical Trials of Antibacterial Drugs: 2015 Update From the Biomarkers Consortium of the Foundation for the National Institutes of Health.” Clinical Infectious Diseases 62(5): 603-607. (link)

These have been enormous efforts — my notes on these project go back to at least 2010! THANK YOU, George!

Second, Arjon Van Hengel (Directorate-General for Research & Innovation, European Commission, Brussels) and Laura Marin (Swedish Research Council, Stockholm) have pulled together a survey paper that explains how initiatives spanning research, innovation, and policy are working together to combat AMR:

This brief paper summarizes the many projects of the recent years (JPIAMRND4BBCARB-XGARDPTATFARG7 Health Ministers, and more) and is a good reference to share if you need to introduce a new colleague to the type of work being done by the AMR community.

All best wishes, –jr
