Memorial Day Conference Week (May 25-31): EASL Barcelona Wednesday + ASCO Chicago Friday Open Back-to-Back, Most Concentrated Peptide-Meeting Cycle Since AACR 2026
The Memorial Day week landing pad in the medical-conference calendar is unusually peptide-heavy. Monday May 25 is the US Memorial Day federal holiday. EASL 2026 (European Association for the Study of the Liver) opens Wednesday May 27 in Barcelona running through Saturday May 30, with Novo Nordisk's ESSENCE Phase 3 liver-safety analyses, Eli Lilly's retatrutide MASLD Phase 3 enrollment status, Boehringer survodutide SYNCHRONIZE-1 forward-look, and MetaVia vanoglipel + resmetirom MASH preclinical work anchoring the peptide-relevant program. ASCO 2026 (American Society of Clinical Oncology) opens Friday May 29 in Chicago running through Tuesday June 2 with the peptide-oncology slate landing across all five days. Combined, the two meetings concentrate the most peptide-mechanism data of any week in 2026 — MASH plus oncology back-to-back. Practitioner press will be split across the two meetings.
