Successful introduction of gene therapy to treat DMD will require careful planning, education, capacity building and prioritization of core i In September 2021, the company reported Positive 1.5-year functional data and patient-reported outcome measures (Pediatric Outcomes Data Collection Instrument, or PODCI) for Patients 4-6 in the ongoing IGNITE DMD Phase I/II clinical trial of SGT-001. The companys multi-omics approach supports the development of cell and gene therapies. SRP-9001: Pfizer plans to begin a Phase III study with PF-06939926 by the end of 2020. AAV has a limited gene size capacity of 5 kilobases (kb), precluding its use for many larger genes. Summer Zemp. 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. Next, the bad: interim data from the phase I/II Ignite DMD trial are disappointing, and the groups stock slid 24% this morning. Importantly for Kornegay, the trial showed the treatment was safe. They are currently developing gene therapies for a range of diseases, including Alzheimer's disease and spinal muscular atrophy. A Non-Viral delivery method is much less likely to elicit an immune response, enabling repeated dosing over months or years. Despite this progress, most DMD patients pass away in their 20s to 30s due to respiratory failure, infection, or cardiomyopathy (dilation of the heart due to overwork). RGX-314, RGX-202, RGX-121, RGX-111, RGX-181, RGX-381. Both Sarepta and Pfizer have collected some promising functional data, commented Hesterlee. Medical Design and Outsourcing. 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. It also has a muscle-specific promoter, which is a DNA element that regulates the activity of a gene called MHCK7. The disease is universally fatal. 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. They are currently developing gene therapies using CRISPR/Cas9 technology. In May, Pfizer, Sarepta, Solid and Genethonjoined armsto investigate why they were all being tripped up by serious safety concerns. 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. 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. ONPATTRO (patisiran), GIVLAARI (givosiran), OXLUMO (lumasiran), AMVUTTRA (vutrisiran). Importantly, there were no serious adverse events (only mild to moderate events). Duchenne Muscular Dystrophy Treatment Outlook, Upcoming Potential Duchenne Muscular Dystrophy Gene Therapy, FAQ For Duchenne Muscular Dystrophy (DMD). But the disease doesnt just affect their legs it affects muscles all over their body. 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. 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. Dystrophin is hypothesized to be involved in the maintenance of sarcolemma. What about a tourniquet and pressure? MDA gave research grants to four labs tasked with finding the cause. WebThere are many challenges facing the management of DMD patients in the United Arab Emirates and Kuwait and most likely other countries within the Middle East. Get Sample Report: https://www.alliedmarketresearch.com/request-sample/2841. Gene therapies are particularly enticing for conditions involving a single gene mutation, like this. 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. Cumulatively, these studies totaled more than 80 patients treated with SRP-9001, demonstrating positive efficacy measures at various time points up to four years after treatment. Moreover, Sarepta recently initiated the first pivotal study on a gene therapy targeting DMD. In May, Pfizer, Sarepta, Solid and Genethonjoined armsto investigate their mutual experience with serious safety concerns. Corticosteroids help dampen down inflammation, said Hesterlee. 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. With funding from biotech companies and the US Department of Defense, a blinded, placebo control study in dogs was approved. Pharma50: 50 Leading Cell and gene therapy companies. 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. Or higher doses to drive the virus into the muscles? Hesterlee added. In 2021, the merger resulted in a new entity known as Astellas Gene Therapy and an associated gene therapy center of excellence. Importantly, our platform is Not Restricted By Gene Size. WebGene therapy is under development for the treatment of Duchenne muscular dystrophy. 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. Explore our blog to know more about Duchenne Muscular Dystrophy Treatment Market. That allowed researchers to test the gene therapy proof-of-concept in DMD patients without worrying about systemic administration right off the bat. Advances in genetic engineering methods have enabled the development of effective gene therapy methods for various diseases based on adeno-associated viruses (AAVs). The collaboration could be worth more than $3 billion. Patients with this form of the muscle-wasting disease don't make enough dystrophin, a protein involved in muscle strength. Companies focusing on DMD gene therapies have proceeded cautiously after a fatal case of myocarditis was observed in Pfizers gene therapy candidate. 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. Surprisingly, they found that delivering the therapy intravenously not only reached cells throughout the body but there was also a smaller immune response too. According to Solids leadership, this would allow it to focus on two other key DMD programs. Could we use histamine? It has a diverse approach to cellular therapy using nicotinamide (NAM) to expand multiple cell types. The whole 2.2 Mb dystrophin gene over 440 times as big is too large to fit inside any AAV. This is based on a proprietary algorithm built from the drugs sales forecast, regulatory milestones, cost forecasts, WACC rate and other proprietary data sources found on GlobalDatas Pharmaceutical Intelligence Center. But there is a limit to how much cargo you can stuff inside these tiny viruses, about 5 kb for AAV. Life-threatening severe DMD complications may eventually develop, such as cardiomyopathy and respiratory difficulties. The companys single-course gene editing programs focus on conditions with a genetically driven, life-long and severely elevated LDL-C such as familial hypercholesterolemia (FH). 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. These findings showed a significant improvement in patient-reported outcomes and provided encouraging evidence of functional benefit 1.5 years after treatment when compared to natural history data. This explains why it largely affects boys as they dont have a backup copy of the gene (they only have one X chromosome). Web2 Department of Gene Therapy, Saad Pharmaceuticals, Tornime 7-26, Tallinn, 10145, Estonia. The companies are looking to extend this collaboration to identify potential underlying mechanisms for these toxicities. In mid-June, Sarepta announced that preliminary results from four boys ages 4-7 years were published in JAMA Neurology. It also selectively licenses its NAV vectors to other biotechnology companies. 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.

But unfortunately, a participant in Pfizers Phase Ib open-label study died unexpectedly. The biopharma is developing genome-edited off-the-shelf CAR-T and CAR-NK cell therapies for various tumor types. Waiting in the wings is Pfizer, whose DMD hopeful PF-06939926encountereda roadblock late last year after a treated patient died. AVR-RD-02, AVR-RD-03, AVR-RD-04, AVR-RD-05, AVR-RD-06. Extensive pre-clinical evidence also formed part of the BLA. The company has multiple cell therapy candidates in pre-clinical and clinical development. One of those labs, Louis Kunkels lab, identified the dystrophin gene first in 1986.. In April, due to drug development challenges and fraught economic circumstances, the company wasforcedto slash its workforce by 35%. The mutated gene is on the X chromosome, making DMD an X-linked 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. In fact, the FDA recently granted SRP-9001 Fast Track designation. Abeona aims to develop therapies for a variety of diseases, including Recessive Dystrophic Epidermolysis Bullosa and Sanfilippo Syndrome Type A. Adverum is a clinical-stage gene therapy company focused on ocular and rare diseases.
