In Regeneron Pharmaceuticals Inc.’s phase I/II Chord study of 12 children with genetic hearing loss, 10 out of 11 have shown improvements after being treated with a gene therapy. “What is really remarkable about this type of therapeutic approach is that the first people who are going to see the impact are not actually the physicians – it’s the families,” Jonathon Whitton, vice president and Regeneron’s auditory global program head, told BioWorld.
The hearing has returned for the first person who has received gene therapy for treating genetic hearing loss in the U.S. Initial results from Akouos Inc.’s phase I/II study showed that within 30 days of receiving AK-OTOF-101, pharmacologic hearing was restored to an 11-year-old who had profound hearing loss from birth.
Six years of collaboration is ending in a buyout, as Decibel Therapeutics Inc. agreed to be acquired by Regeneron Pharmaceuticals Inc. in a deal valued at up to $213 million, including $109 million in equity, with additional payments via contingent value rights linked to clinical and regulatory milestones for DB-OTO, the lead gene therapy program targeting hearing loss.
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.
Decibel Therapeutics Inc. has received clearance of its clinical trial application (CTA) by the U.K.'s Medicines and Healthcare products Regulatory Agency (MHRA) to initiate a phase I/II trial of gene therapy DB-OTO in pediatric patients with congenital hearing loss due to an otoferlin deficiency.
The volatile gene therapy space is getting a boost with Eli Lilly and Co.’s acquisition of Akouos Inc., which only a month before had received the first IND from the U.S. FDA for an adeno-associated virus (AAV)-based hearing loss treatment. Lilly plans to pay about $610 million for the company to get at AK-OTOF, Akouos’ lead candidate for treating hearing loss due to mutations in the otoferlin gene.
Decibel Therapeutics Inc. has received clearance from the FDA for its IND application to initiate a phase I/II trial of DB-OTO in pediatric patients, potentially in infants younger than 2 years of age.
It took resolving issues from two complete response letters for Fennec Pharmaceuticals Inc. to finally land U.S. FDA approval of Pedmark. The injectable formulation of sodium thiosulfate is for reducing the risk of platinum-induced ototoxicity associated with cisplatin in pediatric patients 1 month and older with localized, non-metastatic solid tumors. Approval of the NDA arrived Sept. 20, three days before its Sept. 23 PDUFA date.
