Kiora Pharmaceuticals has obtained exclusive development and commercialization rights outside Asia to KIO-401 (mitucapistat), an investigational oral calpain inhibitor for central retinal artery occlusion (CRAO), from Senju Pharmaceutical. The company plans to initiate a multinational phase 3 registration trial in CRAO in 2027 and expand development into nonarteritic anterior ischemic optic neuropathy (NAION). Announcing the agreement, Shuhei Yoshida, president and CEO of Senju Pharmaceutical, said, “The clinical results generated in Japan support continued global development of this compound as a potential treatment for acute retinal ischemia.” Senju has completed phase 2a and phase 3 clinical studies of the compound, designated SJP-0008 in Japan.
