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. Duchenne Muscular Dystrophy Treatment Outlook, Upcoming Potential Duchenne Muscular Dystrophy Gene Therapy, FAQ For Duchenne Muscular Dystrophy (DMD). It also selectively licenses its NAV vectors to other biotechnology companies. The first U.S. human gene therapy trial directed at Duchenne muscular dystrophy (DMD) was launched yesterday at Columbus (Ohio) Their first gene therapy product, Luxturna, was approved by the FDA in 2017 to treat a form of inherited blindness. The Phase, I/II trial, named AFFINITY DUCHENNE study, which is set to begin in the coming months. The clinical-stage biopharmaceutical company is focused on developing therapies for cancer and other immune-related diseases. With funding from biotech companies and the US Department of Defense, a blinded, placebo control study in dogs was approved. Waiting in the wings is Pfizer, whose DMD hopeful PF-06939926encountereda roadblock in late 2021 after a treated patient died. Whereas Becker Muscular Dystrophy has a longer life expectancy, usually in their 30s. Importantly, there were no serious adverse events (only mild to moderate events). Sarepta had higher dystrophin gene expression and no serious adverse events, like Pfizer saw, Hesterlee added. The companys core focus areas include immuno-oncology and plant sciences. It has a pipeline of in vivo and ex vivo therapies. July 6, 2022. 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. But we were cautious after the high profile death of Jesse Gelsinger in 1999.. Bayer created a cell and gene therapy platform in 2019 within its pharmaceutical division. Attributes of the drug, company and its clinical trials play a fundamental role in drug-specific PTSR and likelihood of approval. For example, the dystrophin gene is too large to fit into the adeno-associated viruses, or AAVs, that are commonly used to deliver gene therapies. WebDr Paul Benson is an oral and facial surgeon, serial entrepreneur and business coach with a diverse portfolio of companies in a variety of industries including healthcare, beauty, Dystrophin, Byrne says, is the largest protein-coding gene in the body and does not fit in an AAV vector. We discovered in 1997 that AAV vectors can be delivered to muscle cells and have a therapeutic benefit, said Byrne. We have developed other critical functions to ensure proper gene delivery. A number of companies are now testing their approaches in the clinic. As the name suggests, gene therapy involves delivering a healthy copy of a mutated gene (in DMDs case dystrophin) into cells. They are currently developing gene therapies using CRISPR/Cas9 technology. We know whats wrong, well fix it! Hesterlee added. The companys allogeneic CAR-T program targets B-cell malignancies. The gene therapy is currently being evaluated in a late-stage clinical development trial for the Duchenne Muscular Dystrophy treatment. Solids is different because it contains the binding spot for an enzyme called nitric oxide synthase both Sarepta and Pfizer cut that portion out.. Afamitresgene autoleucel or afami-cel (formerly ADP-A2M4), ADP-A2M4CD8 SPEAR T-cell therapy. After almost 15 years since the first gene therapy trial for Duchenne muscular dystrophy (DMD) began, the dream of a DMD gene therapy drug is getting closer to a reality. Also, many people already have preexisting immunity to AAV, which may prevent them from ever receiving this gene therapy.

Tune in live this Friday, July 31 at 3pm ET to join the discussion. Although the Phase I trial is not placebo controlled, they can compare treated children to the known natural history of DMD. 1. Today, many AAV-based gene therapy medications are WebMyosana Therapeutics, Inc. is leading the efforts in developing new gene therapies that will slow skeletal muscle degeneration and heart failure to improve the quality of life, increase longevity and reduce the disease burden of Duchenne muscular dystrophy (DMD) and Once inside the cell, the viral vector behaves like a virus and makes the cell produce the protein encoded by the working gene it is carrying, compensating for the original mutated copy. For this next step, Byrne teamed up with Joe Kornegay, now retired, at the Texas A&M University College of Veterinary and Biomedical Sciences. We have developed several monoclonal antibodies against a specific muscle target protein that is present in both skeletal and cardiac muscle. Sarepta and Pfizer are evaluating their lead candidates for gene therapy in the late stages. The companies are looking to extend this collaboration to identify potential underlying mechanisms for these toxicities. 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. This designation is designed to provide regulatory assistance and financial benefits to the therapys clinical research and evaluation, as well as a seven-year period of marketing exclusivity in the United States after regulatory clearance. For example, Eteplirsen (Exondys 51) is expected to cost patients around US$ 300,000 for a treatment course and the cost of the treatment can go as high as US$ 750,000 annually. A Non-Viral delivery method is much less likely to elicit an immune response, enabling repeated dosing over months or years. Duchenne muscular dystrophy (DMD) is a fatal condition caused by a single gene mutation on the X-chromosome being X-linked means only males suffer from the disease. AAV-based gene therapies for x-linked myotubular myopathy (XLMTM), Pompe disease, Duchenne muscular dystrophy and myotonic dystrophy. Germline gene therapy, on the other hand, involves modifying genes in reproductive cells, such as eggs or sperm. Five years ago, scientist He Jiankui shocked his peers and the world with claims that he created the first genetically edited babies. Eventually the heart and breathing muscles are compromised, leading to a premature death from heart or respiratory failure. Now that the dystrophy gene was brought down to a useful size, the next challenge researchers faced was getting the gene therapy from the blood stream into the muscle. The only Duchenne Muscular Dystrophy treatment available are steroids like dexamethasone and gene-targeting therapies including exon skipping from Sarepta Therapeutics and NS Pharma for two small subsets of patients. Gene therapy replaces the mutated gene with a copy using whats called a vector to bring a working copy of the gene into a cell. The leading companies developing gene therapy candidates for DMD are Sarepta Therapeutics, Roche, Pfizer, Solid Biosciences, and Regenxbio. The earlier you treat, the better, but its hard to measure benefit if the children are not yet manifesting a lot of symptoms, so you want to test the children at a stage when theyre progressing, said Hesterlee. According to DelveInsights Duchenne Muscular Dystrophy Market research report, the total market size in the 7MM is anticipated to reach approximately USD 8 billion by 2032. The company aims to develop therapies for neurological disorders and other diseases. Feb 18, 2022 | Reading Time: 8 minutes. In May, Pfizer, Sarepta, Solid and Genethonjoined armsto investigate their mutual experience with serious safety concerns. Back in the mid-1980s, the cause of DMD was still unknown all we knew was that it ran in families, there were no genes associated with the disease yet, Hesterlee explained. Pfizer Inc. Website: www.pfizer.com. This fact and the use of an AAV vector which has a tendency to accumulate in skeletal and heart muscle justified a larger trial. The FDA soon put the Phase Ib study under clinical hold.

In 2019, it spent $4.3 billion to acquire gene therapy specialist Spark Therapeutics. For dogs receiving the treatment, there was an increase in microdystrophin protein in skeletal and heart muscle as well as the diaphragm. At 12-weeks post-treatment, the mean percent of dystrophin expressed in muscles was a whopping 95.8 percent. This loss adds up to about 50 billion yen, or about $390 million (U.S.). The company develops its pipeline products using its multi-platform Precision Genetic Medicine Engine in gene therapy, RNA, and gene editing. The whole 2.2 Mb dystrophin gene over 440 times as big is too large to fit inside any AAV. Sometimes called minidystrophins, there are slight variations between different versions of these shortened genes, but the key is they are all small enough to fit into AAV, explained Hesterlee. They are currently developing gene therapies for a range of diseases, including Duchenne muscular dystrophy and hemophilia. Without this protein, males with Duchenne muscular dystrophy lose muscle cells to damage as they age. Arrowhead Pharmaceuticals specializes in developing therapies to treat intractable diseases by silencing the genes responsible for them. A gene transfer therapy study to evaluate the safety and efficacy of SRP-9001 in participants with Duchenne Muscular Dystrophy (DMD) [NCT05096221].

There are currently three companies with competitive trials in the US: Solid Biosciences, Sarepta Therapeutics, and Pfizer (who bought the DMD platform in 2016 The disease is universally fatal. Before coming to WTWH, he served as content director focused on connected devices at Informa. These exon-skipping therapies are indicated for treatment if certain mutations are present and are designed to increase the production of dystrophin. Duchenne muscular dystrophy (DMD) is a fatal condition caused by a single gene mutation on the X-chromosome being X-linked means only males suffer Medical Design and Outsourcing. The companys platform is based on its pioneering work with phosphorodiamidate morpholino oligomer (PMO) chemistries. This explains why it largely affects boys as they dont have a backup copy of the gene (they only have one X chromosome). However, unlike Sarepta, Pfizer does not have any additional candidates that may join the market and earn market share if its gene therapy treatment fails to win approval, implying that the stakes are higher for the latter. Roughly 1 in 5000 males are born with this condition and there is currently no cure, with the median age of survival 23 years. FDA Approved: December 12, 2019; Company: Sarepta Therapeutics 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.
