Patients with congenital hearing loss could benefit from a gene therapy currently in development. Although there are approaches that could reverse the process in children and young people before it becomes severe, so far, adults do not have any treatment that prevents the progressive deterioration of auditory sensory cells caused by this disease.

The industry is looking, with renewed hope, to the “promise” of messenger RNA (mRNA) therapeutics for a wide range of diseases beyond COVID-19, and not only in vaccine form but also for gene and cell therapies.

Uniqure NV shares (NASDAQ:QURE) closed July 9 at $6.67, up $2.89, or 76%, after the firm made public updated interim data including up to 24 months of follow-up findings from 29 treated patients enrolled in the ongoing U.S. and European phase I/II trials of AMT-130 for Huntington’s disease (HD).

CSL Behring’s expensive hemophilia B gene therapy is to be reimbursed by the U.K. National Health Service, after the company agreed to an outcomes-based payment scheme. The therapy, Hemgenix (etranacogene dezaparvovec), which has a U.K. list price of £2.6 million (US$3.3 million), was approved under a managed access scheme, in which data will be collected over five years to enable both the long-term effectiveness, and any adverse liver toxicity caused by the transgene, to be monitored.

Two days before the PDUFA date, the U.S. FDA handed down a complete response letter (CRL) for Rocket Pharmaceuticals Inc.’s Kresladi (marnetegragene autotemcel), delaying potential approval of the lentiviral-based gene therapy as the first therapeutic option for leukocyte adhesion deficiency type I, a rare, inherited immune disorder. But the Cranbury, N.J.-based company has suggested that delay won’t be long, as the CRL requests only “limited” chemistry manufacturing and controls (CMC) information – additional CMC data were also cited as the reason for the three-month review extension earlier this year.

Exsilio Therapeutics emerged from stealth mode on June 25, 2024, with $82 million from a series A financing that was co-led by Novartis Venture Fund and Delos Capital. The company plans to use naturally occurring, mobile genetic elements to integrate therapeutic genes at a defined location in the genome, making it safer than random integration, which can cause tumor formation.

Sarepta Therapeutics Inc. CEO Douglas Ingram said he expects “ferocious” demand for gene therapy Elevidys (delandistrogene moxeparvovec), granted full approval by the U.S. FDA for Duchenne muscular dystrophy (DMD). Shares of the Cambridge, Mass.-based firm closed June 21 at $16.72, up $37.22, or about 30% on the news.

The good news for Sarepta Therapeutics Inc. is bad news for Pfizer Inc. as the phase III study of its mini-dystrophin gene therapy in Duchenne muscular dystrophy (DMD) has missed its primary endpoint. Now Sarepta’s Elevidys (delandistrogene moxeparvovec), a single-dose, adeno-associated virus-based gene transfer therapy for DMD, is barreling toward a June 21 PDUFA date with the U.S. FDA as the near competition shrinks in the rearview mirror.
