"He pulled himself up the stairs," Jessica says. "MOFs have the capacity to carry larger genetic loads and as a non-viral option, have the added benefit of being a safer prospect for patients than viral alternatives," he said. Conner's mother, Jessica Curran, remembers some advice she got from the doctor who made that 2015 diagnosis: "Take your son home, love him, take him on trips while he's walking, give him a good life and enjoy him because there are really not many options right now.". "We're excited to find a novel way in which these materials can address complex biological issues, including targeting specific medicinal purposes like gene therapy," she said. Once inside the body, these copies of AAV transport their payload of functional dystrophin code into muscle cells, where they replace a faulty version. We Insist: A Timeline Of Protest Music In 2020, A Year In, 1st Patient To Get Gene Editing For Sickle Cell Disease Is Thriving, Gene Therapy Shows Promise For Hemophilia, But Could Be Most Expensive U.S. Drug Ever, First U.S. "I love him. So when Samulski approached the MDA about a grant, it made him an offer. " The success suggests that gene therapy could be poised to change the lives of thousands of children — usually boys — who have Duchenne. "It was the Mount Everest of the gene therapy community and each one of these steps was like setting up base camp.". 'We love the research. Cells are not designed to naturally take up foreign genes or DNA material, and the risks associated with introducing a virus into the body have slowed the progress of research into viral approaches to gene therapy. But scientists still want to see the results of a much larger trial of the therapy, which is likely to begin later this year. And Pfizer is planning a much larger study for later this year. It seemed like the answer. And so was Conner Curran. hide caption. " she says. But his improvement offers strong evidence that the approach can work. The Curran family (from left): Kyle, 9, Jessica, Conner, 9, Chris and Will, 7, with their dog Hunter, a miniature schnauzer. Conner Curran says getting the infusion of what he calls "muscle juice" was no big deal. The MDA had helped fund the discovery of the dystrophin/DMD gene responsible for Duchenne, the most common and most serious form of muscular dystrophy. Biotechnology and the Human Body For Students 8th - 12th. As the day approached, though, Jessica had doubts. So Samulski saw AAV as a potential way to safely transport healthy genes into ailing muscle cells. So did research funding. Samulski explains that every gene therapy trial using a version of AAV has run into problems with side effects, often affecting the liver. The treatment can't bring back the cells he's lost (he remains smaller and weaker than his twin brother, Kyle), but it has allowed the muscle cells he still has to function better. And a video of those dogs eventually made its way to Conner Curran's parents. hide caption, Playing with his brothers, Conner Curran (left) says the gene therapy has really helped him. Since Conner's treatment, eight other boys with Duchenne muscular dystrophy have received two different doses of the gene therapy. Still, scientists and doctors treating these patients agree that AAV therapy has flaws. The teacher would say, 'We let him take a little nap in the classroom,' and I'm thinking, what? Kholood Eid for NPR It's part office building, part lab, and part pharmaceutical manufacturing facility. Get Free Access See Review. So in 2001, Samulski and a small team created Asklepios BioPharmaceutical, or AskBio. Preliminary results on six of them, tested a year after treatment, showed they, too, had improved strength and endurance at an age when boys with Duchenne usually become weaker.
