Frequency Therapeutics Announces Publication of Phase 1/2 Data Showing Hearing Improvements in Acquired Sensorineural Hearing Loss Patients Receiving FX-322 - Seite 2
SNHL accounts for more than 90 percent of all hearing loss and results from damage to auditory sensory hair cells due to chronic noise exposure, aging, certain viral infections or from toxic medications. SNHL impacts more than 40 million people in the U.S. and hundreds of millions of people globally.
“Having a treatment that regenerates sensory hair cells would have a profound impact on the field, providing physicians with a meaningful intervention for restoring hearing loss,” said Ravi N. Samy, M.D., FACS, Professor of Otolaryngology & Neurosurgery and Chief of the Division of Otology/Neurotology at the University of Cincinnati / Cincinnati Children’s. “These exciting early clinical data begin to show the potential of a localized approach to repairing the cochlea, the ability to deliver a treatment to an area of the body that historically has been impossible to access and restore, and above all, clinically meaningful hearing improvements in patients.”
Hearing loss typically begins in higher frequencies and often impacts the ability to hear and distinguish between certain consonants, making it difficult to understand words, especially in noise. Hearing aids amplify sound but do not improve hearing clarity in higher frequencies or repair the underlying damage to the inner ear. FX-322, an injectable treatment candidate made up of two small molecules, is designed to activate progenitor cells (pre-programmed stem cells) to regenerate auditory hair cells in the cochlea and restore hearing function.
“These Phase 1/2 study data build upon the favorable word recognition performances that we previously reported, while bolstering the trends we saw in words-in-noise scores,” said Will McLean, Ph.D., Frequency’s Vice President of Biology and Regenerative Medicine, a Company co-founder and the lead author on the paper. “Increases in speech intelligibility and improvements when listening in noisy environments can have a significant impact on quality of life, and we are excited about the potential of our approach for patients and to advance the field of hearing restoration.”
FX-322 Development Program
FX-322 is Frequency’s lead product candidate for the treatment of acquired SNHL. The Phase 1/2 study was a randomized, double-blind, placebo-controlled, single-dose, multi-center study to assess the safety of FX-322 in 23 patients with stable SNHL. Patients received an intratympanic injection of FX-322 or placebo in one ear during an office-based procedure. In the study, 15 patients received a single dose of FX-322 in one ear while eight patients received placebo.
