Novaliq announced today that the second Phase 3 clinical trial evaluating CyclASol to treat the signs and symptoms of dry eye disease (DED) has randomized more than 50% out of 834 targeted patients, with top-line results expected in the second half of 2021.
The Phase 3 program for CyclASol includes the already completed multi-center, randomized, double-masked, vehicle-controlled trial in 328 patients (ESSENCE-1); the ongoing Phase 3 trial (ESSENCE-2) designed to reconfirm efficacy results of the ESSENCE-1 trial; and a multi-center, open-label, single-arm 12-month safety extension trial (ESSENCE-2 OLE). Results from ESSENCE-2, if positive, will allow for a New Drug Application (NDA) filing to the US Food and Drug Administration in 2022.
“We have been very successful in maintaining a good recruitment rate in the ESSENCE-2 trial through careful selection and support of our clinical sites, despite the COVID-19 pandemic environment. Patients had the opportunity to roll-over into the open-label 12-month safety extension trial and we are pleased to report that the ESSENCE-2 OLE trial has been completely enrolled with a total of 200 participants. Achieving these two enrollment milestones indicates that we are on track with the CyclASol development program to file our first NDA in 2022,” said Sonja Krösser, PhD, Vice President Clinical Development at Novaliq.
CyclASol is a topical anti-inflammatory and immunomodulating ophthalmic solution, containing 0.1% cyclosporine A in EyeSol, developed for the treatment of DED. The previous Phase 2B/3 clinical trial ESSENCE-1, which evaluated the efficacy, safety, and tolerability of CyclASol in patients with DED, has been published in Cornea: The Journal of Cornea and External Disease. In this study, CyclASol demonstrated statistically significant improvements in prespecified endpoints for both signs and symptoms of DED as compared to its vehicle after 4 weeks. Consistent with results from an earlier Phase 2 trial, CyclASol showed clinically meaningful improvements in both corneal and conjunctival staining to monitor the ocular surface condition and improvements in symptoms of dryness compared with those of its vehicle. Additionally, the ESSENCE–1 trial demonstrated that reading speed improves with the corneal staining reduction.
The ongoing ESSENCE-2 trial is a multicenter, randomized, double-masked, vehicle-controlled clinical trial to assess efficacy, safety and tolerability of CyclASol for the treatment of signs and symptoms of DED. The trial is planned to enroll approximately 834 subjects in about 25 US clinical centers. The primary endpoints of the trial are the change from baseline in total corneal staining and in eye dryness score at day 29. The trial will again include the assessment of reading speed as an objective and quantifiable measurement of visual function. The company expects to publish topline data from ESSENCE-2 in the 2nd half of 2021.
