Capricor Therapeutics Inc. received a complete response letter (CRL) from the U.S. FDA on the BLA for deramiocel to treat cardiomyopathy in Duchenne muscular dystrophy patients. The company’s CEO said the letter was unexpected.

Ultragenyx Pharmaceutical Inc. and Mereo Biopharma Group plc, along with investors, had hoped for an early halt to the phase III study of setrusumab in treating brittle bones. They didn’t get it, as the clinical trial’s data monitoring committee wants the study to roll on through its final analysis.

In yet another fail for the Duchenne muscular dystrophy (DMD) field, Taiho Pharmaceutical Co. Ltd.’s pizuglanstat (TAS-205) did not meet the primary endpoint in a phase III trial. The phase III Reach-DMD trial, a randomized, placebo-controlled, double-blind and open-label, extension study of pizuglanstat in patients with DMD showed no significant difference in the mean change from baseline to 52 weeks in the primary endpoint of time to rise from the floor in the ambulatory cohort of the study.
