About the NCX 470 NCX 470 is a new, potentially best-in-class nitric oxide (NO)-donating prostaglandin analog monotherapy being developed to reduce intraocular pressure (IOP) in patients with open-angle glaucoma or ocular hypertension. Glaucoma is a group of eye diseases in which the optic nerve is injured, resulting in peripheral and ultimately central visual field loss and possibly leading to blindness if left untreated. It is frequently linked to abnormally high IOP (~90% of patients) due to blockage or dysfunction of the eye’s aqueous humor drainage system at the front of the eye. In 2020, global sales of treatments targeting glaucoma were over $6.0 billion in a $24.3 billion global market for ophthalmic drugs.

NCX 470 is designed to release both bimatoprost and NO after instillation into the eye. Bimatoprost, marketed under the brand name LUMIGAN^® by Allergan, Inc., is a leading product in the prostaglandin analog class, the most widely used drug class for lowering IOP in patients with open-angle glaucoma or ocular hypertension.
