The editing in human cells and in mice of the survival motor neuron 1 gene (SMN1) restored the levels of SMN protein that the mutation of the SMN2 gene produces in spinal muscular atrophy. Scientists from the Broad Institute in Boston and The Ohio State University reversed the mutation using the base editing technique.
Patients with Leber hereditary optic neuropathy who received bilateral injections of Gensight Biologics SA’s Lumevoq (lenadogene nolparvovec) are continuing to see statistically significant visual improvements three years into the phase III REFLECT trial, but the missed primary endpoint at 1.5 years, along with a series of manufacturing mishaps, have left the gene therapy’s approval prospects uncertain.
The U.S. FDA marked the 40th anniversary of the Orphan Drug Act with Rare Disease Day 2023 as Robert Califf, the agency’s commissioner of food and drugs, opened the day by expressing his wonder and accompanying concern regarding gene editing and gene therapy.
A trio of proposed Medicare drug payment models that made a Feb. 14 debut in the U.S. is playing to mixed reviews. Two of the models to be tested by the U.S. Centers for Medicare & Medicaid Services (CMS) Innovation Center seem to “address the real problems underlying prescription drug pricing – patient out-of-pocket expenses and better payment systems that reward the value a medicine brings to the patient and the overall health care system,” said John Murphy, chief policy officer for the Biotechnology Innovation Organization. But he called the third model, which is expected to restrict Medicare payment for some Part B drugs that have indications with accelerated approval, “an attack on the accelerated approval pathway,” which Congress mandated to spur investment and innovation in areas of unmet medical need.
A phase IIb clinical study has Frequency Therapeutics Inc. reeling and making big changes, including layoffs. The placebo-controlled phase IIb study of FX-322 in treating acquired sensorineural hearing loss by regenerating hair cells in the cochlea missed its primary efficacy endpoint, so the company is discontinuing the program. It’s also shutting down a phase Ib study of FX-345, a program for treating the same indication.
Taysha Gene Therapies Inc.’s stock (NASDAQ:TSHA) struggled Feb. 1 following the U.S. FDA’s recommendation that the company dose more patients in a double-blind, placebo-controlled study of TSHA-120 for the ultra-rare indication giant axonal neuropathy.
After long years of painstaking work, the commercialization of cell and gene therapies picked up pace in 2022, with multiple approvals. More progress is expected in 2023, with several firsts in the offing and products for larger patient populations reaching the market.
Once a rarity, billion-dollar deals are now coming fast and furious. Now three have appeared in only a few days. Gene therapy developer Voyager Therapeutics Inc. and Neurocrine Biosciences Inc. continued a longstanding partnership by agreeing to develop treatments for neurological diseases and for three new programs with rare CNS targets. Cytomx Therapeutics Inc. and Moderna Inc. entered a deal worth a potential $1.24 billion to Cytomx for generating and developing treatments in oncology and non-oncology. In the third deal, Royalty Pharma plc acquired an interest in Ionis Pharmaceuticals Inc.'s royalty in Biogen Inc.'s Spinraza (nusinersen) and Novartis AG's pelacarsen for up to $1.125 billion.
The eyes certainly have it. There are plenty of ocular gene therapies being studied in a crowded field and now there is a new one as Perceive Biotherapeutics Inc. has closed on a $78 million series B financing.
Eli Lilly and Co., through its wholly owned subsidiary Prevail Therapeutics Inc., is delving more deeply into gene therapies. In a new collaboration, Prevail will use privately held Capsida Biotherapeutics Inc.’s adeno-associated virus engineering platform, coupling the tech with Prevail’s gene therapies to target causes of CNS diseases.
