ABOUT SATELLOS BIOSCIENCE INC.

Satellos is a clinical-stage drug development company focused on restoring natural muscle repair and regeneration in degenerative muscle diseases. Through its research, Satellos has developed SAT-3247, a first-of-its-kind, orally administered small molecule drug designed to address deficits in muscle repair and regeneration. SAT-3247 targets AAK1, a key protein that Satellos has identified as capable of helping restore muscle stem cell signaling that is disrupted in DMD. By addressing the loss of dystrophin-dependent cues, SAT-3247 may re-establish the signals that support effective muscle regeneration. SAT-3247 is currently in clinical development as a potential disease-modifying treatment, initially for DMD. Satellos is also working to identify additional muscle diseases or injury conditions where restoring muscle repair and regeneration may have therapeutic benefit and represent future clinical development opportunities.
