Audentes Therapeutics reports 'positive' data from first dose cohort of ASPIRO
Audentes Therapeutics announced positive interim data from the first dose cohort of ASPIRO, a Phase 1/2 clinical trial of AT132 in patients with X-Linked Myotubular Myopathy. ASPIRO is a multicenter, multinational, open-label, ascending dose study to evaluate the safety and preliminary efficacy of AT132 in approximately 12 XLMTM patients less than five years of age. "The early AT132 efficacy data observed in our first dose cohort of patients have exceeded our expectations," stated Dr. Suyash Prasad, Senior Vice President and Chief Medical Officer of Audentes. "At the 12-week timepoint, Patient 1 has improved from a severely compromised baseline to achieve a CHOP-INTEND score and maximal inspiratory pressure that are approaching the ranges normally seen in healthy children. Importantly, Patient 1 has also attained several age-appropriate developmental milestones within this time period, including head-control, rolling over and sitting unassisted. While still early in the trial, we view these initial efficacy data as a promising indicator of the potential for AT132 to bring meaningful benefit to patients and families living with this devastating disease."
