Thats why the first DMD gene therapy trial in the US, which began in 2006, involved injecting the gene therapy directly into the biceps of the children who participated. As a recessive, X-linked condition, it almost exclusively affects males with approximately 200,000 individuals affected worldwide. Patients with this form of the muscle-wasting disease don't make enough dystrophin, a protein involved in muscle strength. It has a diverse approach to cellular therapy using nicotinamide (NAM) to expand multiple cell types. According to data from Solids clinical program, SGT-001 has the potential to slow or stop the Duchenne progression, regardless of genetic mutation or disease stage. Sarepta is a market leader in this category, with three out of every five marketed therapies in the US market addressing DMD. CAP-1002, exosome-based vaccine, engineered exosomes, CDC-exosomes, The startup Cellares aims to enable industrial-scale cell therapy manufacturing with its. The three patients receiving the low dose (1E14 vg/kg) had a mean percent dystrophin expression in muscles of 28.5 percent at two months and 21.2 percent at 12 months, compared to the six patients receiving the high dose (3E14 vg/kg) had 48.4 percent dystrophin expression at two months, three of whom had 50.6 percent at 12 months. He is currently a Professor of Physiology and Biophysics at the University of Washington. July 6, 2022. How Healthcare Apps are Adding New Perspectives to the Healthcare Industry? There are two main types of gene therapy: somatic gene therapy and germline gene therapy. DMD starts to show its effects during early childhood. The United States accounted for approximately 16K prevalent cases of DMD in 2020 which was the maximum in the 7MM. The Phase, I/II trial, named AFFINITY DUCHENNE study, which is set to begin in the coming months. SGT-001 is a novel AAV vector-mediated gene transfer therapy that aims to address the underlying genetic cause of DMD. Its important to realize that the major goal of an animal study is not necessarily to show efficacy, he said. The biotech specializes in creating gene therapies for severe genetic disorders and cancer. It is a recombinant adeno-associated virus serotype 9 (AAV9) capsid containing a shortened version of the human dystrophin gene (mini-dystrophin) controlled by a human muscle specific promotor. Louise Rodino-Klapac, CSO, executive VP and head of R&D, Sarepta Permission granted by Sarepta If approved, SRP-9001, would be the first gene therapy for the muscular degenerative disease known as DMD and is slated for complete evaluation under the accelerated approval path by the end of May 2023. The biotech aims to engineer precision genetic medicine for rare diseases. Our list of prominent cell and gene therapy companies includes top-tier Big Pharma companies as well as smaller privately-held companies. (2022, January 10). Today, many AAV-based gene therapy medications are EMBARK is currently recruiting males with DMD aged 4 to 7 in various locations across the United States. Using this model, they found that delivering intramuscular shots only targets a specific area and provokes an immune response. The life span of boys with DMD has been growing steadily (from in their teens to early 30s) due to improvements in heart and respiratory care.

Arising in one of every 3,500 to 5,000 male infants worldwide, DMD is a rare neuromuscular disease caused by mutations in the gene encoding for the protein dystrophin. WebGene Therapy: Gene therapy for DMD uses selected portions of the dystrophin gene to create a smaller, potentially functional version. The company also has a collaboration with BioMarin. Currently, Matthew is a Venture Partner at Medicxi. PF-06939926 is among the two gene therapies in late-stage development for DMD, with Sarepta Therapeutics SRP-9001 serving as its main competitor.

His innovative Muscle-Targeted, Non-Viral platform has the potential to provide a novel gene therapy treatment for DMD a wide-range of other neuromuscular and cardiac disorders. At the American Society of Gene and Cell Therapy Meeting, the companies theorized that the adverse events were most likely driven by the body's immune responses to the protein expressed by their gene therapeutic. 6 min read. As an example, Dystrophin, the gene responsible for Duchenne muscular dystrophy (DMD) is 14 kb, meaning that only one-third of the dystrophin gene can be "packaged" into AAV. Pfizer Inc. Website: www.pfizer.com. SGT-001 has received Rare Pediatric Disease and Fast Track Designation in the United States and Orphan Drug Designation in the US and EU in 2017. Sarepta and its partner Roche presented new results and analyses on their experimental gene therapy SRP-9001 for the neuromuscular condition Duchenne muscular dystrophy showed consistent, statistically significant functional benefits in individuals. The company is running immuno-oncology and stem cell clinical trials in China with products from its integrated GMP laboratory. Pharmaceutical companies see the value too, with one company, Sarepta, expecting approval of a Duchenne muscular dystrophy gene therapy as early as June of this year. One of those labs, Louis Kunkels lab, identified the dystrophin gene first in 1986.. The companys Tapestri platform can simultaneously. anti-BCMA CA, anti-CD20 CAR, anti-CD19, CD20 BICA, AFP TCR-T.

In May, Pfizer, Sarepta, Solid and Genethonjoined armsto investigate why they were all being tripped up by serious safety concerns. These results have paved the way for ongoing human trials, which have shown a promising ability of this therapy to slow the progression of the disease. In November 2021, RGX-202 was designated as an orphan drug by the FDA for Duchenne Muscular Dystrophy treatment. Unlike more complex conditions, where several genes need repairing or replacing, single gene conditions are easier to rectify. Its pipeline product includes SRP-5051, SRP-9001, SRP-9003 and SRP-5045 indicated for the treatment of DMD, limb-girdle muscular dystrophies (LGDMs) and other neuromuscular and central nervous system disorders.
Krystal Biotech specializes in redosable gene therapy. In May 2022, four companies, Pfizer, Sarepta, Genethon and Solid Biosciences, were all observing serious side effects in their gene therapy clinical trials for DMD. Solids is different because it contains the binding spot for an enzyme called nitric oxide synthase both Sarepta and Pfizer cut that portion out.. The company develops its pipeline products using its multi-platform Precision Genetic Medicine Engine in gene therapy, RNA, and gene editing.

In 2019, it spent $4.3 billion to acquire gene therapy specialist Spark Therapeutics. The Mescope platform consists of an instrument and analysis computer, software, reagents and consumables. These micro-dystrophins might provide only partial improvement of muscle function. Children with DMD tend to get stronger between 3 to 7 years old, then start to decline, Hesterlee explained. "Within the context of Duchenne and other rare diseases, it's a very robust sample size and one that will grow with data from EMBARK.". This would appear to be an easy solution.

Sarepta's gene therapy aims to tackle Duchenne muscular dystrophy. Although we now know DMD is a genetic disease, it wasnt that long ago that researchers didnt know why or how the disease came about. Muscle weakness and atrophy spread from the trunk and forearms to other muscles throughout the body as the disease advances. Although the Phase I trial is not placebo controlled, they can compare treated children to the known natural history of DMD. A number of pharmaceutical companies are developing drugs and therapies to treat DMD. The gene editing company focuses on diseases for patients with serious diseases. The companys platform is based on its pioneering work with phosphorodiamidate morpholino oligomer (PMO) chemistries. An impairment loss is when an asset depreciates in fair market value on the companys financial statements. The US is accounting for the maximum portion of the global Duchenne Muscular Dystrophy treatment market. EMDR (801) 436-5597.
