Infinity cuts research jobs after lead drug disappoints in Phase II

15 June 2016

American firm Infinity Pharma (Nasdaq: INFI) has been rocked by disappointing results from Phase II trials of its lead candidate Dynamo (duvelisib), leading the Massachusetts-based biotech to announce the closure of its discovery research organization, and placing the continuation of its collaboration with US drug major AbbVie (NYSE: ABBV) in doubt.
