CAMBRIDGE, MA, USA I February 17, 2023 I Sarepta Therapeutics, Inc. (NASDAQ:SRPT), the leader in precision genetic medicine for rare diseases, today announced that the first patient has been dosed in Study SRP-9003-102. Also known as VOYAGENE, Study 9003-102 is a phase 1 study of SRP-9003 (bidridistrogene xeboparvovec) for the treatment of limb-girdle muscular dystrophy Type 2E/R4 (LGMD2E). VOYAGENE is a U.S.-only study enrolling ambulant patients aged 18 years or older and non-ambulant patients, ages 4-50 years, using clinical process SRP-9003 material. “Sarepta has previously disclosed positive expression and function data from our initial clinical study, Study SRP-9003-101, exploring multiple doses of SRP-9003 in a younger, ambulant population. The VOYAGENE study, which also utilizes clinical material, provides an opportunity to generate additional data in a broader population of patients while we finalize plans for a global, Phase 3 study using commercially representative process material that we intend to begin later this year,” said Louise Rodino-Klapac, Ph.D., executive vice president, chief scientific officer and head of research and development, Sarepta Therapeutics. “Sarepta is applying lessons from across our gene therapy portfolio to help advance the development of our investigational LGMD programs as efficiently as possible. Current treatments for LGMD are limited to symptom management and we remain fully committed to working with urgency to bring forward new treatments that can slow the progression of this disease, improve mobility and enhance the quality of life for individuals living with LGMD2E and other LGMD subtypes.” More information on the VOYAGENE study is available at https://genesislgmd.com/study/voyagene . About SRP-9003 (bidridistrogene xeboparvovec) SRP-9003 (bidridistrogene xeboparvovec) is an investigational gene therapy that uses the AAVrh74 vector, which is designed to be systemically and robustly delivered to skeletal, diaphragm and cardiac muscle, making it an ideal candidate to treat peripheral neuromuscular diseases. SRP-9003 also uses the MHCK7 promoter, chosen for its ability to robustly express in the heart, which is critically important for patients with limb-girdle muscular dystrophy Type 2E (LGMD2E), also known as beta-sarcoglycanopathy and LGMDR4, many of whom die from pulmonary or cardiac complications. About Limb-girdle Muscular Dystrophy Limb-girdle muscular dystrophies are genetic diseases that cause progressive, debilitating weakness and wasting that begins in muscles around the hips and shoulders before progressing to muscles in the arms and legs. Sarepta’s six LGMD gene therapy programs in development include LGMD2E/R4, LGMD2D/R3, LGMD2C/R5, LGMD2B/R2, LGMD2L/R12 and LGMD2A/R1, which together represent more than 70 percent of known LGMD cases. Patients with LGMD2E begin showing neuromuscular symptoms such as difficulty running, jumping and climbing stairs before age 10. The disease, which is an autosomal recessive subtype of LGMD, progresses to loss of ambulation in the teen years and often leads to early mortality. There is currently no treatment or cure for LGMD2E. About Sarepta Therapeutics Sarepta is on an urgent mission: engineer precision genetic medicine for rare diseases that devastate lives and cut futures short. We hold leadership positions in Duchenne muscular dystrophy (DMD) and limb-girdle muscular dystrophies (LGMDs), and we currently have more than 40 programs in various stages of development. Our vast pipeline is driven by our multi-platform Precision Genetic Medicine Engine in gene therapy, RNA and gene editing.

FALLS CHURCH, Va., July 5, 2022 /PRNewswire/ -- On September 23, 2022 at 10am EDT, a coalition of limb-girdle muscular dystrophy (LGMD) nonprofit organizations will lead an Externally-Led Patient Focused Drug Development Meeting (EL-PFDD). This online event is open to the public with registration required. The meeting will be summarized in a Voice of the Patient report which, along with recorded footage of the meeting, will be publicly available. This EL-PFDD will focus on six subtypes of LGMD: LGMD2A/R1, LGMD2C/R5, LGMD2D/R3, LGMD2E/R4, LGMD2F/R6, and LGMD2I/R9. The goal of this meeting is to provide the U.S. Food and Drug Administration (FDA), clinicians, medical product developers, and academic researchers an opportunity to hear perspectives from individuals with LGMD on the health effects, daily impacts, treatment goals, and decision factors considered when seeking out or selecting a treatment. This meeting is being conducted as a parallel effort to FDA's EL-PFDD initiative, a commitment under the fifth authorization of the Prescription Drug User Fee Act (PDUFA V) to more systematically gather patients' perspectives on their conditions and available therapies to treat their conditions. The meeting agenda will include speakers and panelists who are living with LGMD2A/R1, LGMD2C/R5, LGMD2D/R3, LGMD2E/R4, LGMD2F/R6, and LGMD2I/R9, as well as caregivers of people living with these six subtypes. The morning sessions will focus on symptoms that matter most to them, and the toll these take on daily living. The afternoon session will include discussions on experiences with current treatments and attitudes towards future treatments, including tolerance to potential risks. For the first time, representatives from Coalition to Cure Calpain 3, CureLGMD2I, the Kurt+Peter Foundation, the LGMD2D Foundation, the McColl-Lockwood Laboratory for Muscular Dystrophy Research, and the Speak Foundation, have joined together to organize this event. Jointly referred to as the LGMD Coalition, these nonprofit organizations are encouraging members of the global patient community to make their voices heard. Individuals living with the subtypes of LGMD listed above, as well as their caregivers, are invited to participate in the meeting by partaking in live polling and by calling and writing in with comments. Academic investigators, clinicians, regulators, and industry representatives are encouraged to watch the meeting and incorporate patient/caregiver perspectives when developing and reviewing new therapies to best meet the needs and expectations of our community. Pre-registration is available at . The LGMD Coalition is grateful for support from our sponsors, AskBio, Edgewise Therapeutics, ML BioSolutions, Sarepta Therapeutics, and Vita Therapeutics. We also acknowledge our Advocacy Partners, the Muscular Dystrophy Association and the LGMD Awareness Foundation. About LGMD LGMD is a term used for a group of rare neuromuscular diseases which are inherited and cause muscle weakness and wasting. The muscles most affected are those closest to the body (proximal), specifically the muscles of the shoulders, upper arms, pelvic area, and thighs. More than 30 subtypes of LGMD exist. Together, LGMDs have an estimated prevalence of about 2 in every 100,000 individuals. There is currently no cure for any subtype of LGMD. About the LGMD Coalition The LGMD Coalition is a group of six 501(c)3 nonprofit organizations -- Coalition to Cure Calpain 3, CureLGMD2I, the Kurt+Peter Foundation, the LGMD2D Foundation, the McColl-Lockwood Laboratory for Muscular Dystrophy Research, and the Speak Foundation – that are collaborating to host an LGMD EL-PFDD focused on subtypes LGMD2A/R1, LGMD2C/R5, LGMD2D/R3, LGMD2E/R4, LGMD2F/R6, and LGMD2I/R9.
