Biotech and pharma’s European calendar runs through national and regional life-sciences fairs rather than one dominant show – Pharmapack in Paris for packaging and CDMO, BIOSPAIN and BioFIT for drug discovery, and smaller regional gatherings in the Baltics and Italy. Ranked by verified attendance.
1Rank
CDMO and bioprocessing 27-28 Jan 2027, Paris Expo Porte de Versailles 6,500 attendees
Informa's pharmaceutical packaging and drug delivery show in Paris, covering CDMO and bioprocessing as a major theme alongside device and packaging innovation.
Why it is hereThe largest event on this desk, and the reference gathering for CDMO and manufacturing-side biotech rather than drug discovery.

Attendance figures come from each event’s own record and organiser statements. Three of the five events – BioFIT, Life Sciences Baltics and MIT4LS – run a partnering format built around scheduled one-to-one meetings rather than open exhibition, which favours founders prepared with a specific investor or partner target list.
