Fresh on the heels of a newly-announced $1.24 billion pact on a rheumatoid arthritis drug, Rigel Pharmaceuticals says it's nearing another deal on its psoriasis program. "We are continuing to work on R348 as a topical agent for psoriasis. It is likely that in the next three months we will announce a deal on R348," Chief Operating Officer Raul Rodriguez told Reuters. Rigel is looking to team up with a company with a sharp dermatological or ophthalmic focus before taking the therapy into a mid-stage trial. Report
