PURPOSE: This study compares outcomes of therapy with OC-01 (varenicline solution) for dry eye disease in study eyes and nonstudy fellow eyes of participants in 2 pivotal clinical trials.
METHODS: All 891 patients randomized to receive OC-01 (varenicline solution) 0.03 mg, OC-01 (varenicline solution) 0.06 mg, or vehicle control (VC) in each nostril twice daily for 28 days in the Phase IIb ONSET-1 (Evaluation of the Efficacy of OC-01 Nasal Spray on Signs and Symptoms of Dry Eye Disease) and Phase III ONSET-2 trials were included in this post hoc analysis. One eye was designated as the study eye. The mean change from baseline in anesthetized Schirmer test score (STS) and the percentage of eyes achieving a ≥10-mm STS improvement were compared between treatments in study and fellow eyes overall and by baseline Eye Dryness Score.
FINDINGS: In the study eyes, the mean STS improvement from baseline to day 28 was 10.4 mm, 10.5 mm, and 4.9 mm in the 0.03 mg, 0.06 mg, and VC groups, respectively; comparable values in nonstudy fellow eyes were 8.7 mm, 8.8 mm, and 2.7 mm, respectively. The percentages of study eyes achieving a ≥10-mm STS improvement were 48.1%, 48.4%, and 25.9%, respectively, whereas the comparable values in nonstudy eyes were 42.9%, 43.9%, and 19.7%, respectively. No significant treatment-subgroup interactions were observed in study or fellow eye STS outcomes by baseline Eye Dryness Scores <40 and ≥40 (p > 0.05 for all).
IMPLICATIONS: OC-01 (varenicline solution) nasal spray had significant tear film production improvements compared with VC in both study and fellow eyes. These findings suggest efficacy across a broad spectrum of presenting disease severity.
