These genetic alterations manifest as developmental delays and, in more progressed forms of DMD, as limb weakness, loss of independence and difficulties in breathing. He is currently a Research Associate Professor in the Department of Physiology and Biophysics at the University of Washington. The trick was using higher doses and the right serotypes of AAV to move the vector out of the bloodstream and into muscle, Hesterlee added. 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. Published: Jul 29, 2020 The companies are looking to extend this collaboration to identify potential underlying mechanisms for these toxicities. ARO-AAT, ARO-APOC3, ARO-ANG3, ARO-HSD, ARO-C3. Its platform-agnostic approach incorporates both adeno-associated viral vector (AAV) and lentiviral vector (LVV) programs. SRP-9001 (2E14 vg/kg dose) is currently being investigated in open-label Phase I/II study (Study 101). The tricky part is getting the gene inside the cell. 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 Dystrophin, Byrne says, is the largest protein-coding gene in the body and does not fit in an AAV vector. Patients with this form of the muscle-wasting disease don't make enough dystrophin, a protein involved in muscle strength. He has extensive experience in the Bio-pharmaceutical field, with positions at Pfizer, as Medical Director of Rare Diseases and, more recently Moderna, where he was responsible for taking the first mRNA therapeutics for rare diseases into the clinic. Duchenne Muscular Dystrophy (DMD) is an X-linked disease that is inherited. At 12 months post-injection, the boys had sustained, significant improvement in minidystrophin expression and improved muscle function (measured via the NSAA rating scale). 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. Thankfully, another group of researchers working on a milder form of Duchenne muscular dystrophy called Becker muscular dystrophy found that in these patients that large chunks of the gene were missing but a protein was still produced. These DMD therapies may, at best, slow the progression of Duchenne. The company has two approved chimeric antigen receptor (CAR T) cell therapies in hematologic malignancies that use two distinct targets targeting separate blood cancers. Published: Nov 28, 2022 It also has a muscle-specific promoter, which is a DNA element that regulates the activity of a gene called MHCK7. This is accomplished using a vector, usually a virus or nanoparticle, as a trojan horse to sneak the healthy gene into the cell. 1985 - 2023 BioSpace.com. PF-06939926 was granted Fast Track designation in 2020. 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.

When expanded it provides a list of search options that will switch the search inputs to match the current selection. The most common type of vector is a virus called adeno-associated virus (AAV), which works using the natural ability of viruses to enter cells and hijack cellular machinery to produce viral proteins encoded by viral genes. By the time patients are in their 20s, they are unable to move, breath, and ultimately suffer cardiac failure. 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. Eteplirsen, golodirsen, casimersen, SRP-9001, GALGGT2, GNT 0004. In January, The FDA approved Regenxbios request to conduct a Phase I/II clinical trial in the United States to assess the safety and efficacy of RGX-202, its experimental gene therapy for Duchenne Muscular Dystrophy (DMD). This microdystrophin encodes a functional protein surrogate expressed in muscles and helps stabilize essential associated proteins such as neuronal nitric oxide synthase (nNOS). Solid Biosciences therapy, called SGT-001, involves a microdystrophin gene carried by an AAV9 viral vector. What about a tourniquet and pressure? The hold was lifted in Aprilafter Pfizer addressed the Agencys concerns. Throughout the late 1990s and early 2000s, researchers tinkered with the dystrophin gene, figuring out what parts were needed and how much they could trim out to still have a functional protein. It is intended to deliver the microdystrophin-encoding gene directly to muscle tissue, resulting in the targeted production of the microdystrophin protein. Its proprietary capsid could expand the reach of gene therapy for diseases conventionally untreatable with conventional capsids.
