Abstract Title:
An artificial tear containing flaxseed oil for treating dry eye disease: A randomized controlled trial.
Abstract:
PURPOSE: To evaluate the efficacy and safety of a nano-emulsion artificial tear (OM3) containing carboxymethylcellulose (CMC) and glycerin, flaxseed oil and castor oil, and three osmoprotectants (levocarnitine, erythritol, and trehalose) compared with an artificial tear (Refresh Optive Advanced [ROA]) containing the same ingredients with the exception of trehalose and flaxseed oil.METHODS: In this multicenter, double-masked, randomized, two-arm, parallel-group, 6-visit study (screening, baseline, and days 7, 30, 60, and 90), subjects with dry eye disease underwent an open-label, 7-day run-in with CMC 0.5% (Refresh Plus), before 1:1 randomization to OM3 or ROA for 90 days (both instilled≥2 daily). Ocular Surface Disease Index (OSDI; primary endpoint change from baseline at day 90), tear film breakup time (TBUT), and ocular staining (combined/corneal/conjunctival) were assessed; change from baseline in these parameters was calculated at each timepoint. Treatment-related adverse events (AEs) were assessed at each visit.RESULTS: Overall, 242 subjects were randomized (OM3, n = 120; ROA, n = 122). At day 90, significant improvements in OSDI, ocular staining and TBUT were evident in both treatment groups. Significant (P
