Ocumension files NDA in China for Nicox’s NCX 470 glaucoma therapy, marking a key regulatory milestone for the ophthalmic asset
Executive summary: Ocumension submitted an NDA to China’s NMPA for NCX 470, a glaucoma therapy co-developed with Nicox, on August 10, 2026. The filing represents a pivotal step toward commercializing NCX 470 in China, a major market for glaucoma treatments, and validates the therapeutic potential of Nicox’s nitric oxide-based platform.
Who is involved: Nicox (France), Ocumension (China), and China’s NMPA regulatory authority.
Likely next: NMPA review and potential approval within 12 months; if successful, Ocumension will initiate commercial launch in China under the partnership agreement.
Nicox announced that its partner Ocumension has submitted a New Drug Application (NDA) to China’s NMPA for NCX 470, a nitric oxide-donating bimatoprost eye drop designed to lower intraocular pressure in glaucoma patients. The filing follows positive Phase 3 results and positions the drug for potential approval in one of the world’s largest ophthalmic markets. This advancement reflects ongoing Sino-French collaboration in drug development and could accelerate commercialization timelines for NCX 470 in Asia.
