Wyeth Pharmaceuticals said Tuesday that it has formed an exclusive worldwide collaboration with Catalyst Biosciences Inc. to develop treatments for hemophilia and other bleeding conditions.

Collegeville, Pa.-based Wyeth Pharmaceuticals, a division of Wyeth (NYSE:WYE) said it will pay South San Francisco, Calif.-based Catalyst $21 million upfront. Total payments for research funding and milestones could exceed $500 million, the companies said.

Wyeth Research President Mikael Dolsten said the relationship is “an opportunity to expand Wyeth’s hemophilia franchise.”

Catalyst has a drug candidate, known as CB 813, for treatment and prevention of acute bleeding in hemophilia patients.
