Memorial Day Monday US News Vacuum — EASL Tuesday May 26 ASCO Embargo, EASL Wednesday May 27 Opens
Monday May 25 is the US Memorial Day federal holiday; SEC filings, FDA actions, US company press releases pause for the day. The week's news cycle picks up Tuesday with ASCO's embargoed virtual press briefing for credentialed media (a preview of Late-Breaking Abstracts ahead of the May 29 Annual Meeting opening in Chicago) and Wednesday with EASL 2026's opening in Barcelona. The combined Tuesday-Wednesday cycle delivers the most concentrated peptide-mechanism data of any week in 2026 — Altimmune pemvidutide IMPACT MASH, Novo Nordisk ESSENCE liver safety, Madrigal Rezdiffra portal hypertension data, Eli Lilly retatrutide MASLD Phase 3 status, and Boehringer survodutide SYNCHRONIZE-1 preview at EASL plus the peptide-oncology cohort at ASCO (Bicycle, Avacta, BriaCell, BioVaxys, Crinetics, Sapience, Corbus). The Hepcludex approval Friday plus the EASL plus ASCO double-meeting structure makes this the highest-volume peptide-news week of 2026 to date.
