ELK GROVE VILLAGE, Ill., April 25, 2012 (GLOBE NEWSWIRE) -- Repligen Corporation (Nasdaq:RGEN) today announced positive results from a Phase 1 study to evaluate the pharmacokinetic (PK) and safety profile of RG3039, a novel small molecule drug candidate for the potential treatment of spinal muscular atrophy (SMA). SMA is a inherited neurodegenerative disease in which symptoms of progressive damage to motor neurons including loss of muscle function typically appear very early in life and often progress to severe physical disability and early loss of life. The Phase 1 trial was a blinded, ascending, single dose study of RG3039 administered to 32 healthy volunteers. The study results demonstrate that RG3039 was well tolerated at all doses administered, with no serious adverse events reported. The data also showed evidence of a dose-related drug response resulting in 90% inhibition of the target enzyme. These outcomes may help to establish appropriate RG3039 dosing regimens for future studies, including potential efficacy studies in SMA patients.
