Spinal Muscular Atrophy Program Advances with Additional Product Candidate Entering Clinical Development
-Phase 1 Study Initiated in Healthy Volunteers with New SMN2 Splicing Modifier – RG7916 –
SOUTH PLAINFIELD, N.J., Jan. 7, 2016 /PRNewswire/ — PTC Therapeutics, Inc. (Nasdaq: PTCT) today announced that RG7916, an additional SMN2 splicing modifier from the company’s joint development program with Roche and the SMA Foundation in spinal muscular atrophy (SMA), has entered clinical development. RG7916 is designed to shift SMN2 pre-mRNA splicing toward the production of full length SMN mRNA. A Phase 1 study in healthy volunteers has been initiated to investigate the safety, tolerability, pharmacokinetics and pharmacodynamics of RG7916.
“We are pleased to initiate clinical development of a second candidate in our SMA collaboration,” said Stuart W. Peltz, Ph.D., Chief Executive Officer, PTC Therapeutics, Inc. “The goal of this Phase 1 study is to understand more about the safety and activity of RG7916 and be in a position to compare the profiles of each of our development compounds to determine the best path forward for our SMA program. SMA is the most common genetic cause of infant mortality and one of the most common rare diseases. Currently there are no available therapies to treat the underlying cause of the disease. PTC and our collaboration partners are committed to advancing potential solutions for SMA patients through our SMN2 alternative splicing program.”
Two compounds are currently in clinical development within the SMA program, RG7800 and RG7916. The most advanced compound, RG7800, is the subject of a Phase 2 randomized, double-blind, placebo-controlled trial called Moonfish in adult and pediatric patients with SMA. Dosing in the Moonfish trial was suspended in April 2015 and the trial was placed on clinical hold to investigate a non-clinical safety finding observed in a longer-term animal study.
The SMA program was initially developed by PTC Therapeutics in partnership with the SMA Foundation in 2006 to accelerate the development of a treatment for SMA. In November 2011, Roche gained an exclusive worldwide license to the PTC/SMA Foundation SMN2 alternative splicing program. The development of RG7800 and RG7916 is being executed by Roche and overseen by a joint steering committee with members from PTC, Roche, and the SMA Foundation.
About Spinal Muscular Atrophy (SMA)
Spinal muscular atrophy (SMA) is a genetic neuromuscular disorder that is the leading genetic cause of mortality in infants and toddlers caused by a missing or defective survival of motor neuron 1 (SMN1) gene, which results in reduced levels of SMN protein. The homologous SMN2 gene is predominantly spliced to a truncated mRNA, and only produces small amounts of functional SMN protein. Insufficient levels of SMN protein are responsible for the loss of motor neurons within the spinal cord leading to muscle atrophy and death in its most severe form. It is estimated that this devastating disease affects 1 in every 11,000 children born. Currently, there are no therapies available for SMA.
About PTC Therapeutics, Inc.
PTC is a global biopharmaceutical company focused on the discovery, development and commercialization of orally administered, proprietary small molecule drugs targeting an area of RNA biology we refer to as post-transcriptional control. Post-transcriptional control processes are the regulatory events that occur in cells during and after a messenger RNA, or mRNA, molecule is copied from DNA through the transcription process. PTC’s internally discovered pipeline addresses multiple therapeutic areas, including rare disorders, oncology and infectious diseases. PTC has discovered all of its compounds currently under development using its proprietary technologies. PTC plans to continue to develop these compounds both on its own and through selective collaboration arrangements with leading pharmaceutical and biotechnology companies.
