Audentes Therapeutics Announces First Patient Enrolled in the INCEPTUS Study

Audentes Therapeutics, Inc. recently announced that the first patient has been enrolled in INCEPTUS, a prospective study designed to characterize the disease presentation in children living with X-Linked Myotubular Myopathy (XLMTM). The study is evaluating subjects prior to potential enrollment in ASPIRO, the planned Phase I/II clinical study intended to evaluate the safety and preliminary efficacy of AT132, the Audentes product candidate for treatment of XLMTM.

“The initiation of enrollment for INCEPTUS is an important first step in the clinical development of AT132 for the treatment of XLMTM and a notable milestone for Audentes,” said Dr. Suyash Prasad, Audentes’ Senior Vice President and Chief Medical Officer. “The burden of the disease of XLMTM to children and families is considerable, and we are grateful to those who have agreed to participate in the study.”

INCEPTUS is an international study of boys with XLMTM, ages three years or younger, designed to characterize their individual disease presentation, with a specific focus on respiratory measurements and assessment of muscle strength and function. Patients enrolled in INCEPTUS will be evaluated over a three to twelve-month period prior to their potential participation in ASPIRO. INCEPTUS is designed to serve as a longitudinal baseline and within-patient control for subjects who enroll in the ASPIRO study, while also facilitating the operational aspects of ASPIRO once initiated.

Audentes plans to file investigational new drug applications for AT132 with North American and European regulatory authorities in the first quarter of 2017. The company expects preliminary data from the ASPIRO study in the fourth quarter of 2017. For additional information on INCEPTUS, please visit www.clinicaltrials.gov.

X-Linked Myotubular Myopathy (XLMTM) is a rare, inherited disorder characterized by severe muscle weakness, respiratory impairment, and early mortality. There is no approved treatment for the condition. It is caused by mutations in the MTM1 gene, which encodes a protein called myotubularin. Myotubularin plays an important role in the development, maintenance, and function of skeletal muscle cells. XLMTM affects approximately 1 in 50,000 newborn males worldwide. Audentes is developing AT132 for the treatment of XLMTM in collaboration with Genethon (www.genethon.fr). AT132 is a novel product based on AAV gene therapy technology.

Audentes Therapeutics is a biotechnology company focused on developing and commercializing gene therapy products for patients living with serious, life-threatening rare diseases. The company has four products in development, AT132 for the treatment of X-Linked Myotubular Myopathy (XLMTM), AT342 for the treatment of Crigler-Najjar Syndrome, AT982 for the treatment of Pompe disease, and AT307 for the treatment of the CASQ2 subtype of Catecholaminergic Polymorphic Ventricular Tachycardia (CASQ2-CPVT). It is a focused, experienced and passionate team committed to forging strong, global relationships with the patient, research, and medical communities. For more information, visit www.audentestx.com.
