MedTech 100 is a financial index calculated using the BIG100 companies covered in All Rights Reserved. The BLA was supported by data from three studies: SRP-9001-101, SRP-9001-102 and SRP-9001-103. A third component provides a linking role that helps to deliver the DNA to the nucleus of the muscle cells. WebThe Roche Groups bold commitment to gene therapy collaborations across the organisation and industry are a stake in the ground: the possibility and potential of using There are two main types of gene therapy: somatic gene therapy and germline gene therapy. Dystrophin, the largest gene in the human body, encodes a muscle protein responsible for keeping muscle cells from pulling themselves apart when the muscle is working, like a shock absorber for the cell, as Hesterlee described. Specialized blood tests (such as creatine kinase) are also used to assess the presence and amounts of certain proteins in muscle (immunohistochemistry). MHCK7 is intended to increase gene activity in the heart and skeletal muscles, which are the most affected muscle groups in DMD patients. Dystrophin, Byrne says, is the largest protein-coding gene in the body and does not fit in an AAV vector. The company announced in October 2020 that its gene therapy product had also received Fast Track designation from the FDA. It has six programs in clinical development. AAV has a limited gene size capacity of 5 kilobases (kb), precluding its use for many larger genes. It could convert this disease from a devastating diagnosis to a manageable disease in the next 10 years.. 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. The NAV AAV8 vector, which has been used in numerous clinical trials, and a well-characterized muscle-specific promoter (Spc5-12) are used in RGX-202 to support the delivery and targeted expression of genes throughout skeletal and heart muscle. Attributes of the drug, company and its clinical trials play a fundamental role in drug-specific PTSR and likelihood of approval. Eventually the heart and breathing muscles are compromised, leading to a premature death from heart or respiratory failure. Connect with him on LinkedIn or email at [emailprotected], Copyright 2023 WTWH Media LLC. All three companies are using different versions of minidystrophin, explained Hesterlee. The company then opened U.S. enrollment for a Phase III trial of the therapy that was already underway in the U.K., Canada and other countries. We had been studying in dogs a disease that phenotypically appeared analogous to Duchenne dystrophy for several years going back into the early 80s, said Kornegay. Focuses on developing and commercializing gene therapies for rare and life-threatening neurological genetic diseases. Recently Serepta released the topline results from Part 2 of Study SRP-9001-102 (Study 102), an ongoing, double-blind, randomized, placebo-controlled clinical study to assess the safety, efficacy, and tolerability of a single dose of SRP-9001 (delandistrogene moxeparvovec) in 41 patients with Duchenne Muscular Dystrophy, 21 of whom were in the placebo crossover cohort. SRP-9001 is a gene therapy candidate for Duchenne Muscular Dystrophy treatment. In recent years, weve gotten much better at detecting benefits in the boys even when they are in the early stages and improving, so trials have started to skew younger, including children as young as 4 years old.. According to the companys press release, preliminary data from nine boys with DMD (ages 6-12) showed the therapy was well-tolerated during intravenous infusion. At the American Society of Gene and Cell Therapy Meeting, the companies theorized that the adverse events were most likely driven by the bodys immune responses to the protein expressed by their gene therapeutic.

Reference: Barry Byrne, Joe Kornegay, et al., Assessment of systemic AAV-microdystrophin gene therapy in the GRMD model of Duchenne muscular dystrophy, Science Translational Medicine (2023), DOI: 10.1126/scitranslmed.abo1815, Feature image: The protein dystrophin. Somatic gene therapy involves modifying genes in non-reproductive cells, such as cells in the skin or blood. Matthew is a trained Cardiologist with a Ph.D. in cardiovascular physiology. The tricky part is getting the gene inside the cell. Within the context of Duchenne and other rare diseases, its a very robust sample size and one that will grow with data from EMBARK.. Another challenge hinges on the fact that the gene is delivered using a virus, making the gene therapy an immunization in a way. They can help slow down disease progression, but tackling inflammation only addresses one downstream effect.. The company is running immuno-oncology and stem cell clinical trials in China with products from its integrated GMP laboratory. WebDMD gene therapy aims to deliver a working version of the dystrophin gene, so that the body can produce functioning dystrophin. Founded in 1992, bluebird bio is a biotech company based in Cambridge, Massachusetts that focuses on developing gene therapies for rare genetic diseases and cancer. Were still learning from human studies, it just shows that not every model will be predictive of the human clinical finding, he said. Operations, Competitive Intelligence, Competitive Landscaping, and Mergers & Acquisitions. Now, after serving three years in a Chinese prison for practicing medicine without a license, he faces obstacles and critics as he tries to re-enter science. NIH, U.S. National Library of Medicine, ClinicalTrials.gov. AAVs are also common viruses some people have already been exposed to AAVs naturally and would never know because they cause no symptoms. Also working on a gene therapy for DMD is Solid Biosciences, which has also encountered trouble. Sarepta Therapeutics said topline results from Part 2 of its study SRP-9001-102, an ongoing, randomized, double-blind, placebo-controlled clinical trial to evaluate the safety, efficacy and tolerability of a single dose of its gene therapy for the progressive neuromuscular condition Duchenne muscular dystrophy, showed statistically SGT-001 is a novel AAV vector-mediated gene transfer therapy that aims to address the underlying genetic cause of DMD. As a recessive, X-linked condition, it almost exclusively affects males with approximately 200,000 individuals affected worldwide. In late 2019, Astellas Pharma Inc. (TSE: 4503) agreed to acquire Audentes Therapeutics for approximately $3 billion. Duchenne muscular dystrophy (DMD) is a severe genetic disorder characterized by progressive muscle degeneration and consequent muscle weakness. Also working on a gene therapy for DMD is Solid Biosciences, which has also been having trouble. EDIT-101, EDIT-103, EDIT-102, EDIT-202, EDIT-301. While AAV vectors work great for delivering gene therapies to muscle cells, as Barry Byrne, co-author of the new study and professor of pediatrics at the University of Florida, explained, they have a size limitation. WebGene Therapy: Gene therapy for DMD uses selected portions of the dystrophin gene to create a smaller, potentially functional version. In this review, we highlight current opportunities for Duchenne muscular dystrophy gene therapy, which has been known thus far as an incurable genetic disease. Its important to realize that the major goal of an animal study is not necessarily to show efficacy, he said. It employs a non-lethal modified virus (AAVrh74) with a high affinity for muscle tissue, allowing for targeted delivery. In September 2021, Astellas Pharma reported a fourth patient death in the AT132 clinical 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. Anywhere from 10 to 80 percent of DMD patients, depending on the serotype in question, have preexisting antibodies against AAVs, meaning they are not eligible for gene therapy, Hesterlee elaborated. The companys gene therapy product candidates use AAV viral vectors from its proprietary gene delivery platform. We have developed antibodies to a specific muscle protein, which binds to the cell and delivers the appropriate gene into skeletal & cardiac muscle. Arrowhead Pharmaceuticals specializes in developing therapies to treat intractable diseases by silencing the genes responsible for them. GlobalDatas report assesses how GALGT2 (Nationwide Childrens)s drug-specific PTSR and Likelihood of Approval (LoA) scores compare to the indication benchmarks. Mondays BLA acceptance positions Roche and Sarepta as the leaders of a tight race to bring a gene therapy for DMD over the regulatory finish line. DMD has a life expectancy of 16 to early 20s. In fact, the FDA recently granted SRP-9001 Fast Track designation. Novartis is a Swiss multinational pharmaceutical company that has been involved in gene therapy research since the 1990s. Their first gene therapy product, Zynteglo, was approved by the European Medicines Agency in 2019 to treat a form of inherited anemia. GlobalDatas Likelihood of Approval analytics tool dynamically assesses and predicts how likely a drug will move to the next stage in its clinical pathway (PTSR), as well as how likely the drug will be approved (LoA). The biopharma is developing genome-edited off-the-shelf CAR-T and CAR-NK cell therapies for various tumor types. Details >>, provide genotype and phenotype data from the same cell across thousands of single cells, 25 novel therapies set to shape the landscape of medicine in 2023, Genascence believes gene therapy can transform the treatment of knee osteoarthritis, Drug Discovery & Developments top stories of 2022. As part of the FDA's accelerated approval pathway, Roche and Sarepta have also initiated the EMBARK trial, a global, randomized, double-blinded and placebo-controlled study of SRP-9001 in DMD patients aged 4 to 7 years old. All rights reserved. This microdystrophin encodes a functional protein surrogate expressed in muscles and helps stabilize essential associated proteins such as neuronal nitric oxide synthase (nNOS). But it took another 30 years to be able to apply this knowledge to develop effective drugs., Although corticosteroids can slow the progression of DMD to some extent, they dont address the underlying issue the lack of functional dystrophin. However, for Duchenne muscular dystrophy gene therapies, the size of the dystrophin gene is a problem. AAV9 is a type of AAV that is particularly good at getting into muscle cells. Can FcRn Antagonists Be The Game-Changer in the Generalized Myasthenia Gravis (gMG) Treatment Market? The Food and Drug Administration approved the therapies after studying a few dozen boys.
