Selecta and AskBio Receive FDA Rare Pediatric Disease Designation for Methylmalonic Acidemia Gene Therapy
WATERTOWN, Mass., and Research Triangle Park, N.C., Oct. 20, 2020 — Selecta Biosciences, Inc. (NASDAQ: SELB) and Asklepios BioPharmaceutical, Inc. (AskBio), today announced the U.S. Food and Drug Administration (FDA) has granted Rare Pediatric Disease Designation to MMA-101 for the treatment of isolated methylmalonic acidemia (MMA) due to methylmalonyl-CoA mutase (MMUT) gene mutations. The FDA grants Rare Pediatric Disease Designation to incentivize development of new treatments for serious and life-threatening diseases that primarily affect children ages 18 years or younger with fewer than 200,000 people affected in the U.S. The Rare Pediatric Disease designation program allows for a sponsor who receives an approval for a product to potentially qualify for a voucher that can be redeemed to receive a priority review of a subsequent marketing application for a different product.
“This Rare Pediatric Disease designation from the FDA highlights the significant unmet medical need that Selecta and AskBio are seeking to address with MMA-101 for this rare metabolic disorder,” said Carsten Brunn, Ph.D., chief executive officer of Selecta Biosciences. “When used with AAV gene therapy vectors, Selecta’s ImmTOR aims to inhibit the immune response to the AAV vector, potentially allowing re-dosing of gene therapies. Ongoing clinical programs will focus on evaluating product candidate performance in patients who may have been underdosed or those who may lose transgene expression over time. We’re honored to receive this recognition and look forward to advancing this program in hopes of helping young patients affected by MMA and their families.”
“MMA is a serious and potentially life-threatening inherited metabolic disorder that presents in patients from newborns to adulthood,” said Sheila Mikhail, J.D., CEO and co-founder of AskBio. “AskBio is committed to delivering transformative genetic medicines for rare diseases like this one, and the Rare Pediatric Disease designation helps us continue development of MMA-101.”
AskBio and Selecta expect to initiate a Phase 1 clinical trial of MMA-101 and ImmTOR for patients with MMA in 1H 2021.
About Methylmalonic Acidemia
Methylmalonic acidemia (MMA) is a rare monogenic disorder in which the body cannot break down certain proteins and fats. This metabolic disease may lead to hyperammonemia and is associated with long-term complications including feeding problems, intellectual disability, chronic kidney disease and inflammation of the pancreas. Symptoms of MMA usually appear in early infancy and vary from mild to life-threatening. Without treatment, this disorder can lead to coma and in some cases death.
About Selecta Biosciences, Inc.
Selecta Biosciences Inc. (NASDAQ: SELB) is leveraging its clinically validated ImmTOR™ platform to develop tolerogenic therapies that selectively mitigate unwanted immune responses. With a proven ability to induce tolerance to highly immunogenic proteins, ImmTOR has the potential to amplify the efficacy of biologic therapies, including redosing of life-saving gene therapies, as well as restore the body’s natural self-tolerance in autoimmune diseases. The company’s first program aimed at addressing immunogenicity to AAV gene therapies is expected to enter clinical trials in early 2021 in partnership with AskBio for the treatment of methylmalonic acidemia (MMA), a rare metabolic disorder. A wholly-owned program focused on addressing IgA nephropathy driven by ImmTOR and a therapeutic enzyme is also in development among additional product candidates. Selecta recently licensed its Phase 3 clinical product candidate, SEL-212, in chronic refractory gout to Sobi. For more information, please visit www.selectabio.com.
Founded in 2001, Asklepios BioPharmaceutical, Inc. (AskBio) is a privately held, fully integrated AAV gene therapy company dedicated to developing life-saving medicines that cure genetic diseases. Its pipeline includes clinical-stage programs in Pompe disease and congestive heart failure and a diverse preclinical portfolio of therapeutics targeting neuromuscular, CNS and other diseases, as well as out-licensed clinical indications for hemophilia (Chatham Therapeutics, acquired by Takeda) and Duchenne muscular dystrophy (Bamboo Therapeutics, acquired by Pfizer). AskBio’s gene therapy platform includes Pro10™, an industry-leading proprietary cell line manufacturing process, and an extensive AAV capsid and promoter library. With global headquarters in Research Triangle Park, North Carolina, and European headquarters in Edinburgh, UK, the company has generated hundreds of proprietary third generation AAV capsids and promoters, several of which have entered clinical testing. An early innovator in the space, the company holds more than 500 patents in areas such as AAV production and chimeric and self-complementary capsids.
