Olesoxime

Drug Name: Olesoxime
Company: Roche Pharmaceuticals
Location: Switzerland
Website: http://www.roche.com
Drug Type: Small Molecule
Conditions: ALS, Spinal Muscular Atrophy
Mechanism Type: Mitochondrial protectant
Mechanism: Olesoxime is a cholesterol-oxime compound that targets and preserves mitochondrial integrity and function under conditions of cellular stress by modulating the mitochondrial permeability transition pore, and as a result promotes the function and survival of neurons and other cell types under disease-relevant stress conditions. The compound improved muscle function and reduced astrogliosis and microglial activation in preclinical studies in SOD1 ALS mouse models, but failed Phase III trials in ALS.
U.S. Status for ALS: Discontinued
