About ASP0367

ASP0367, a selective modulator of PPARδ, has the potential to be a first-in-class remedy for PMM. In a preclinical examine, ASP0367 elevated the expression of PPARδ goal genes and enhanced mitochondrial operate in fibroblasts collected from sufferers with PMMs. A section I examine in wholesome adults demonstrated dose-dependent elevated expression of PPARδ goal genes and ASP0367 doses had been discovered to be protected and effectively tolerated on this examine. ASP0367 can be being developed as a possible remedy for Duchenne muscular dystrophy. Different Section Ib research are additionally below preparation. For extra info on medical trials, go to
