After dropping development in December of its lead program, Spruce Biosciences Inc. has found new life by acquiring a BLA-ready enzyme replacement therapy for the rare genetic neurodegenerative disease Sanfilippo syndrome type B. If approved, the therapy, tralesinidase alfa, could bring Spruce a priority review voucher.
While Spruce Biosciences Inc.’s tildacerfont missed its phase II primary endpoint in classic congenital adrenal hyperplasia (CAH) last March, the U.S. FDA approved Crenessity (crinecerfont) from Neurocrine Biosciences Inc. for treating pediatric and adult CAH patients.

Publication this summer of phase II data with Spruce Biosciences Inc.’s CRF1 antagonist, tildacerfont, for classic congenital adrenal hyperplasia (CAH) in the Journal of Clinical Endocrinology and Metabolism (JCEM) highlighted the indication where a handful of players are known to be active.
