I confirmed my suspicions as ANTH did in fact in-license several of its product candidates, including its lead drug in Phase 3 targeting ACS. See: http://investor.anthera.com/releasedetail.cfm?ReleaseID=424037 which details the in-license agreement with LLY and Shionogi in September 2006.
ANTH’s Varespladib is an anti-inflammatory, not an anticoagulant. To assess whether ANTH is a good investment, I would want to know the outcome of the phase-2 ACS study described in http://clinicaltrials.gov/ct2/show/NCT00743925 .
The clinicaltrials.gov entry says this study finished in Apr 2010, but it does not contain the results.
