Following an eventful couple of months with Elevidys (delandistrogene moxeparvovec-rokl), Sarepta Therapeutics has announced that the efficacy supplement for its biologics license application (BLA) of the Duchenne muscular dystrophy (DMD) gene therapy has received priority review by the FDA. As per the 16 February press release, the purpose of the efficacy supplement is to change Elevidys’ accelerated approval to a traditional approval while also expanding the therapy’s label to treat all DMD patients with a confirmed mutation in the DMD gene. The FDA has set a priority review goal date of 21 June 2024 and will not discuss the supplement in an advisory committee meeting. Elevidys, which was granted approval in June 2023, is currently indicated to treat ambulatory pediatric DMD patients between the ages of four and five years with a confirmed mutation in the DMD gene. The single-dose gene transfer therapy uses a recombinant adeno-associated virus vector serotype ...
The third quarter marked a momentous one for Sarepta Therapeutics, bringing the long-anticipated launch of its Duchenne muscular dystrophy (DMD) gene therapy Elevidys. After traveling a tumultuous road to the June approval, Sarepta reaped $69.1 million from Elevidys’ first quarter on the market. The number was more than enough to beat analysts’ expectations of between $20 million and $24 million. Sarepta stayed mum on exactly how many patients have received an infusion and instead provided revenue as a marker for uptake, CEO Doug Ingram said on Sarepta’s third-quarter earnings call. The drug is priced at $3.2 million per infusion. Also on the call, Sarepta reiterated its confidence that its phase 3 EMBARK study can potentially support a label expansion for Elevidys despite missing its primary endpoint. The company’s discussions with FDA leadership have shown that the agency is open to the idea of a label expansion “if supported by review ...
By Tristan Manalac Sarepta Therapeutics on Monday posted topline data from the Phase III EMBARK study, showing that its Duchenne muscular dystrophy gene therapy Elevidys (delandistrogene moxeparvovec-rokl) fell short of its primary efficacy endpoint, unable to significantly improve functional mobility versus placebo. Nonetheless, based on what the company calls “robust evidence” of “clinically meaningful treatment benefit” across all EMBARK’s pre-specified key functional secondary endpoints, Sarepta will push through with filing for a label expansion for Elevidys. “We have shared the EMBARK topline results with FDA leadership and they have confirmed that, based on the totality of the evidence, they are open to such label expansion if supported by review of the data, and that they intend to proceed rapidly with consideration of the submission,” Sarepta CEO Doug Ingram said in a statement. In EMBARK, a randomized, two-part crossover and placebo-controlled study, Sarepta dosed 125 Duchenne muscular dystrophy (DMD) patients aged ...
After Sarepta Therapeutics overcame several regulatory hurdles to finally win FDA approval for its Duchenne muscular dystrophy (DMD) gene therapy Elevidys, the company now faces the prospect of more FDA scrutiny because a pivotal study on the drug has failed on the primary endpoint. The endpoint, a measure of motor function called the North Star Ambulatory Assessment (NSAA), failed to reach statistical significance in the phase 3 EMBARK study, Sarepta said in a Monday release. Despite this result, Sarepta Chief Scientific Officer Louise Rodino-Klapac, Ph.D., touted “clinically meaningful” effects seen across the trial’s secondary endpoints. Speaking on a Monday conference call, Rodino-Klapac said Sarepta plans to file for a label expansion to treat “all DMD patients” and to convert the drug’s accelerated approval into a traditional nod. Sarepta CEO Doug Ingram said the study “met the standard” to show “evidence of effectiveness.” He added that the results show that the ...
The US Food and Drug Administration (FDA) has granted NS Pharma’s NS-089/NCNP-02 breakthrough therapy designation in a move that will help ramp up the future treatment options for Duchenne Muscular Dystrophy (DMD). The news follows another recent FDA win for NS Pharma, which is owned by Japanese pharmaceutical company Nippon Shinyaku, after its therapy was awarded a rare paediatric disease (RPD) designation earlier in July. A first-in-human clinical trial (NCT04129294) in six Japanese patients with DMD amenable to exon 44 skipping showed that the therapy increased dystrophin protein expression, and improved the motor function of patients as measured by The North Star Ambulatory Assessment. NS-089/NCNP-02 is an antisense nucleotide that helps cells skip over a particular exon. In the case of DMD patients, this is the mutated – and therefore dysfunctional – exon 44 in the DMD gene. Nippon Shinyaku discovered NS-089/NCNP-02 in a joint research project with the National ...
After several delays and a narrow advisory committee vote, Sarepta’s Duchenne muscular dystrophy (DMD) gene therapy has finally won an accelerated approval. The FDA’s approval for Elevidys comes one month behind the agency’s prior schedule and in a restricted patient population. But a win is a win for Sarepta. Specifically, the drug is approved to treat ambulatory patients ages 4 to 5 years with a confirmed mutation in the DMD gene. Sarepta is charging Elevidys, a one-time gene therapy, at a list price of $3.2 million, CEO Douglas Ingram told investors during a call Thursday. He pointed to an analysis suggesting the drug could be cost-effective at $5 million. Ingram expects the launch to take a few months to pick up, based on logistical and policy issues to address, he told investors. As opposed to an treatment outcome-based payment approach that has been adopted by other existing gene therapies to ...
By Heather McKenzie https://www.biospace.com/ Pictured: Sarepta logo on a building/courtesy of Sarepta Therapeutics Those in the Duchenne muscular dystrophy and gene therapy spaces hoping for a milestone decision by May 29 will have to wait approximately three more weeks as the FDA set a new action date of June 22 for Sarepta’s gene therapy for the neuromuscular disease. The FDA told the company Wednesday “it requires modest additional time to complete the review, including final label negotiations and postmarketing commitment discussions,” according to Sarepta’s announcement. The company went on to say that the FDA indicated it is “working toward potentially granting an accelerated approval for SRP-9001” for DMD patients aged 4-5 years. If approved, SRP-900 would be the first FDA-authorized gene therapy for DMD. Sarepta’s shares were down 14% in pre-market trading Wednesday.
Roche is paying more than $1 billion upfront for the ex-U.S. rights to Sarepta Therapeutics’ Duchenne muscular dystrophy (DMD) gene therapy SRP-9001. The deal comes days after Roche advanced its push into gene therapies by closing the takeover of Spark Therapeutics. Sarepta has linked SRP-9001 to microdystrophin expression levels of up to 96% in early clinical tests, leading it to start a 24-patient placebo-controlled trial that is due to deliver data next year. Coupled to a safety profile that so far makes SRP-9001 look a better prospect than rival gene therapies from Pfizer and Solid Biosciences, the efficacy data have put Sarepta at the forefront of efforts to develop a one-shot treatment for DMD. That has attracted the attention of Roche. The Swiss drugmaker is set to pay $750 million in cash and $400 million in equity upfront for the ex-U.S. rights to SRP-9001. Sarepta is also in line to ...
Dystrophin is a major protein involved in the functionality of muscles. If a mutation occurs, the production of dystrophin becomes inhibited which leads to the development of Duchenne muscular dystrophy (DMD). DMD usually leads to muscle or heart failure, followed by premature death. There was no effective treatment available till date.
Corticosteroids are a standard first-line treatment for Duchenne muscular dystrophy, but these drugs have many side effects. FDA approval of Italfarmaco’s Duvyzat is the first nonsteroidal drug to pass the agency’s regulatory bar for treating this rare disease. By FRANK VINLUANDuchenne muscular dystrophy has several approved drugs, including a gene therapy that provides children who have the rare, inherited muscle-wasting disease the option of a one-time treatment. But each of these therapies only treats certain defined patient groups. While corticosteroids can reach more Duchenne patients, they introduce many side effects. The FDA just approved the first nonsteroidal Duchenne drug. The late Thursday approval of Italfarmaco drug givinostat covers patients age 6 and older and spans all genetic variants that drive the inherited disease. The twice-daily oral suspension will be marketed under the brand name Duvyzat. In an email, Italfarmaco said Duvyzat’s price has not yet been set. The Milan, Italy-based ...
