Preliminary data on three additional patients enrolled in a small open-label study of Immune Pharmaceuticals Inc.'s bertilimumab, an experimental treatment for the rare blistering disease bullous pemphigoid (BP), continued to suggest it may offer an effective alternative to systemic corticosteroids, a standard but imperfect therapy for the condition.
