Arena Pharma's R&D lead quits 6 months into the job, replaced by Alder CMO

In the summer, Arena Pharmaceuticals hired Chris Cabell, M.D., as its chief medical officer, senior vice president and head of R&D, but now he’s out the door.

Cabell, who was hired in June to try to help Arena set a new R&D path away from its ill-fated attempts in obesity, has retired and resigned, according to the company.
