Nicox Reaches 50% Enrollment Threshold in U.S. Phase 2 Study with NCX 470 Ahead of Schedule

Sophia Antipolis, France
Nicox SA (Euronext Paris: FR0013018124, COX), an international ophthalmology company, today announced it has reached the 50% patient enrollment threshold of its multicenter, United States (U.S.) Phase 2 clinical study evaluating NCX 470 ahead of schedule. Nicox’s lead product candidate, NCX 470, is a novel, second-generation nitric oxide (NO)-donating prostaglandin analog for the lowering of intraocular pressure (IOP) in patients with open-angle glaucoma or ocular hypertension. NCX 470 has demonstrated a 2 to 3 mmHg greater IOP reduction than bimatoprost in head-to-head comparisons in preclinical models. Bimatoprost, marketed under the brand LUMIGAN®, is the current market leader by sales value among glaucoma therapies in the U.S.
The Phase 2, multicenter, double-masked, 28-day, parallel group, dose response study aims to evaluate the efficacy and safety of NCX 470 ophthalmic solution compared to latanoprost ophthalmic solution, 0.005% in patients with elevated IOP due to open-angle glaucoma or ocular hypertension. The study is expected to randomize 420 patients in clinical sites across the U.S. The primary endpoint of the study is the mean reduction in diurnal IOP after 28 days of treatment, while the overall objective is to identify the appropriate dose of NCX 470 to be advanced into Phase 3 clinical studies.
Tomas Navratil, PhD, Executive Vice President, Head of Development of Nicox, said: “We are encouraged by the brisk patient recruitment rate of our NCX 470 Phase 2 study, and we are grateful for the support and the commitment of the patients and clinical sites in the NCX 470 study. We believe that NCX 470 has the potential to become a leading first-line therapy for glaucoma patients due to its IOP lowering superiority versus the market leader as demonstrated in preclinical models.”
Nicox expects to report top-line data from this Phase 2 study in the second half of 2019.
Glaucoma is a group of ocular diseases in which the optic nerve is injured, leading to peripheral and, ultimately, central visual field loss. Glaucoma can eventually lead to blindness if not treated and is currently considered to be one of the three leading causes of irreversible blindness worldwide. Glaucoma is frequently linked to abnormally high intraocular pressure (IOP) due to blockage or malfunction of the eye’s aqueous humor drainage system in the front of the eye. Current medications are targeted at reducing IOP to slow the progression of the disease. The requirement for multiple medications to lower an individual patient’s IOP to their target level highlights the need for more effective treatments.
In 2017, worldwide sales of treatments targeting glaucoma were $5.0 billion representing 27% of the $18.6 billion worldwide market for ophthalmic drugs. In the U.S., sales of treatments targeting glaucoma totalled $2.6 billion in 2017 or 32% of the $8.1 billion U.S. market for ophthalmic drugs. Of the U.S. sales of treatments targeting glaucoma, $1.3 billion, or approximately 50%, was sales of prostaglandin analogs, of which more than 90% were the branded products, TRAVATAN Z® (travoprost ophthalmic solution), 0.004% and LUMIGAN (bimatoprost ophthalmic solution), 0.01%. Currently, we estimate that 3.5% of the worldwide population between 40 and 80 years of age are affected by the most common forms of glaucoma, and we estimate that, in 2017, 36.1 million prescriptions were written in the U.S. annually for glaucoma drugs.
About NCX 470
NCX 470 is a new chemical entity formulated as an ophthalmic solution of this novel, second generation nitric oxide (NO)-donating prostaglandin analog in development for the lowering of intraocular pressure (IOP) in patients with open-angle glaucoma and ocular hypertension. NCX 470 is designed to release both bimatoprost and NO following instillation into the eye. Bimatoprost, marketed under the brand name LUMIGAN by Allergan, Inc., is one of the leading products in the class of prostaglandin analogs, the most widely used class of drugs for IOP-lowering in patients with open-angle glaucoma or ocular hypertension. Nicox believes that NCX 470 has the potential for greater IOP lowering activity than either bimatoprost or Bausch + Lomb’s VYZULTA (latanoprostene bunod ophthalmic solution), 0.024%, given bimatoprost’s efficacy profile and the NO-mediated activity.
