Communicable E52: ESCMID Global Trials, PETER PEN and ASTARTE
Show notes
In this collaborative episode of Breakpoints and Communicable, the hosts revisit the “trial run” session from ESCMID Global, a format designed to facilitate critical discussion of major infectious diseases trials. This episode focuses on two studies addressing bloodstream infections caused by third‑generation cephalosporin-resistant Enterobacterales [1].
Mical Paul (Rambam Health Care Campus, Israel) joins the podcast to discuss the PETER PEN trial [1,2], comparing piperacillin/tazobactam with meropenem, including its design, interim analyses, and interpretation alongside prior data such as MERINO. The episode also features Jesús Rodríguez‑Baño (University of Seville, Spain), who presents a post hoc analysis of the ASTARTE trial [1,3], comparing temocillin and carbapenems.
This episode was edited by Lacy Worden and was peer reviewed by Jeanette Bouchard (Duke Antimicrobial Stewardship Outreach Network (DASON) Durham, NC, USA).
