PurposeThe aim of this study was to evaluate the safety and efficacy of OTX-101, a clear nanomicellar aqueous solution of cyclosporine, in the treatment of dry eye disease (DED).Patients and methodsThis was a 12-week multicenter, randomized, prospective, double-masked, vehicle-controlled, dose-ranging clinical trial. Subjects were adults aged ≥18 years, with a total conjunctival staining score of ≥3 and ≤9, and global DED symptom score ≥40 (0–100 visual analogue scale). Following a 14-day vehicle run-in, subjects were randomized in a 1:1:1 ratio to twice daily treatment with OTX-101 0.09%, OTX-101 0.05%, or vehicle for 84 days. Co-primary efficacy end points were changes, from baseline to Day 84, in the total lissamine green conjunctival staining score in the designated study eye and in the global symptom score (both eyes). Secondary end points included total corneal fluorescein staining score, tear breakup time, and Schirmer’s test score.ResultsIn total, 455 subjects were randomized. Subjects treated with active drug experienced greater improvement in conjunctival staining than vehicle-treated patients (P<0.01 for both concentrations). All groups demonstrated improvements in global symptom score, but there were no differences among groups. Nominally significant differences were found between the active drug arms and vehicle for corneal staining scores and Schirmer’s test scores. Most treatment-emergent adverse events were mild in severity; no serious ocular adverse events were reported.ConclusionsBoth concentrations of OTX-101 met the co-primary sign end point (conjunctival staining) but not the co-primary symptom end point. OTX-101 0.09% demonstrated a notable impact on multiple signs of DED relative to vehicle and was well-tolerated.

A fixed combination of travoprost 0.004% and timolol 0.5% produced clinically relevant IOP reductions in patients with open angle glaucoma or ocular hypertension that were comparable to concomitant therapy with its components. Safety and tolerability of the fixed combination were also equivalent to concomitant therapy. Travoprost 0.004%/timolol 0.5% fixed combination offers IOP reduction equivalent to concomitant therapy, with potential benefits that include convenience (fewer bottles and drops per day), improved compliance, cost savings (based on fewer co-payments), and elimination of potential washout effects.
