As a youth, Charles Deguire did everything he could to help three uncles with muscular dystrophy. One of them, Jacques Forest, had designed a clever makeshift arm that could pick up objects. He built it with whatever was available — including windshield wiper motors, parts of a desk lamp, and…

Mary Bodzo’s daughter Krista is now 27. Born with spinal muscular atrophy (SMA), her condition is stable, and Bodzo attributes that to the amino acid diet that Krista began at age 5. “We completely believe that changing her diet was what kept her stable,” Bodzo said in an interview with…

As Congress begins debate this week to overhaul the U.S. tax code, lawmakers should leave the Orphan Drug Act (ODA) — and the tax incentives it offers pharmaceutical companies to develop therapies for rare diseases — off the table. That’s the message being pushed by the National Organization for…

Three filmmakers are raising funds for a feature-length documentary about how science and the rare disease community’s needs came together to make Biogen’s Spinraza the first approved treatment for spinal muscular atrophy (SMA). Their month-long, $25,000 Kickstarter campaign ends in four days, at 2:48 p.m. Sunday, Oct. 22.

A Phase 2 clinical trial evaluating the efficacy and safety of RG7916 in children and adults with type 2 or 3 spinal muscular atrophy has advanced into a second and possibly pivotal phase. The study is part of a development program jointly led by PTC Therapeutics, Roche and the SMA Foundation. An interim analysis from the trial's first part demonstrated an exposure-dependent increase in the SMN protein, which is deficient in SMA patients. RG7916 continues to be well-tolerated at all doses and no drug-related safety findings led to any patients withdrawing from part one. RG7916 is drug that can be taken by mouth that impacts SMN2. Because SMA is caused by a defect in the SMN1 gene, the SMN2 gene has been explored as a potential replacement to guarantee the production of the SMN protein. RG7916 is also being investigated in babies with type 1 or infant-onset SMA in a Phase 2 trial called FIREFISH. This study, running at sites in the U.S. and Europe, is currently recruiting infants ages 1 to 7 months old. PTC Therapeutics and the SMA Foundation initially began working on this potential therapy in 2006, and Roche began to participate in 2011, when it acquired an exclusive worldwide license to this splicing program.  The U.S. Food and Drug Administration (FDA) designated RG7916 an orphan drug for the treatment of SMA in January 2017.

Kavita Krishnaswamy is so determined to gain independence for herself and others living with physical disabilities that she spends up to 20 hours a day designing devices. “After I get ready for caregivers and have something to eat, I start working, working, working,” she said in an interview with SMA…

Parents and caregivers of patients with spinal muscular atrophy (SMA) take great interest in orphan drug development, soaring healthcare costs, patient assistance programs and controversial “right-to-try” legislation — all issues on the agenda during the upcoming Rare Disease & Orphan Products Breakthrough Summit. “One of the chief challenges of 21st-century…

Spinraza (nusinersen) may provide more benefits to infants with spinal muscular atrophy (SMA) if the treatment is started early, Biogen reported during presentations at the ongoing 22nd International Congress of the World Muscle Society in St. Malo, France. But the treatment can also provide benefits to SMA patients…

Preliminary data from the Phase 2 SUNFISH trial show PTC Therapeutics' investigative drug RG 7916 increases production of the SMN (survival motor neuron) protein in types 2 and 3 spinal muscular atrophy patients. The results were presented by PTC Therapeutics at the 22nd International World Muscle Society (WMS) Congress in St. Malo, France, Oct. 3-7. Part 1 of the study assessed the safety, tolerability, effectiveness, and pharmacological profile of several doses of orally administered RG 7916 in both ambulatory and non-ambulatory SMA patients. Part 2 will include 150 non-ambulatory patients to determine the safety and effectiveness of the recommended dosage of RG 7916 selected from Part 1. An open-label extension study will follow. The development and production of RG7916 is part of a joint effort between PTC Therapeutics, Swiss multinational Roche, and the SMA Foundation. Earlier this year, RG7916 was granted orphan drug and fast track designation by the FDA for the treatment of patients with SMA. PTC Therapeutics created an SMA research program in 2006 in partnership with the SMA Foundation to pursue a therapy for the devastating disease. In November 2011, Roche obtained an exclusive worldwide license to the PTC/SMA Foundation program studying alternative splicing (synthesis of different protein variants from the same messenger RNA sequence) of the SMN2 gene.

The gene therapy developer AveXis will start a pivotal clinical trial of AVXS-101 for people with SMA type 1. U.S. Food and Drug Administration officials agreed to the trial after AveXis submitted information the agency requested on the drug's manufacturing process and other matters. The request was made at a meeting the sides held in May. AveXis did not say in its announcement whether the pivotal trial would be a Phase 2 or Phase 3 study. The company has completed a Phase 1 trial of AVXS-101. Most pivotal trials are Phase 3, but occasionally they can be Phase 2. . AVXS-101 is a proprietary gene therapy for SMA types 1 and 2. Designed to deliver a functional copy of an SMN gene to motor neuron cells, it aims to prevent additional muscle degeneration. The pivotal trial in SMA type 1 – called STR1VE – will be an open-label, single-arm, single-dose, multi-center study. It will evaluate the safety and effectiveness of a one-time dose of AVXS-101 delivered intravenously or directly into the blood circulation. Researchers will administer a dose established in a Phase 1 trial that they confirmed with new analytical methods that the FDA reviewed. The dose was also extensively tested in a mouse model of SMA. AveXis expects to enroll in the trial at least 15 patients with SMA Type 1 younger than six months of age. One of the trial's primary objectives will be to see if AVXS-101 can help an 18-month-old infant sit without help for at least 30 seconds. Another primary objective will be to help an infant achieve event-free survival at 14 months of age, and to see whether AVXS-101 helps patients thrive — that is,  not requiring feeding support, tolerate thin liquids and maintain weight. Another secondary objective will be to help infants get off ventilator support at 18 months of age. Updates of these studies are expected at the end of the year.
