RESUMEN

Aim: Herein, we report safety outcomes for varenicline solution nasal spray (VNS) within the context of clinical trial discontinuation, contrasting those with discontinuation outcomes from topical cyclosporine and lifitegrast clinical trials. Materials & methods: 1061 subjects were randomized across three clinical trials to receive either VNS 0.06 mg, VNS 0.03 mg, VNS 0.006 mg or vehicle control. Subjects who discontinued from treatment were noted and assigned to their appropriate categories. Results: Despite treatment emergent adverse events, 93.5% of subjects receiving VNS completed the treatment period. By comparison, only 80% of subjects in the integrated clinical trials for cyclosporine ophthalmic emulsion and 91% of subjects in the integrated trials for lifitegrast ophthalmic solution completed the full treatment period, respectively. Conclusion: In clinical trials, VNS demonstrated improvements in dry eye disease signs and symptoms, was well-tolerated, and had an overall completion rate >93%. Conventional dry eye treatments (e.g., cyclosporine and lifitegrast) noted considerably higher discontinuation rates in their clinical trials.

RESUMEN

SIGNIFICANCE: There is a clinical necessity for dry eye disease treatments that perform across a broad range of presenting patient severities. Varenicline solution nasal spray (VNS), a unique cholinergic agonist ocular surface-sparing nasal spray therapy, demonstrated significant improvement in both signs and symptoms of dry eye disease in subjects with mild, moderate, and severe symptoms as the clinical studies enrolled a more real-world patient population. PURPOSE: This study evaluated efficacy outcomes for VNS in patients with mild-moderate and severe dry eye disease. METHODS: An analysis of integrated data from two randomized clinical trials, ONSET-1 (NCT03636061) and ONSET-2 (NCT04036292) (vehicle control [VC], n = 294; VNS 0.03 mg, n = 308), was performed. Adults 22 years or older with dry eye disease, Ocular Surface Disease Index score of ≥23, corneal fluorescein staining score of ≥2 in ≥1 regions/≥4 all regions, and Schirmer Test Score (STS) of ≤10 mm (no restrictions on Eye Dryness Score [EDS]) were included in this study. Efficacy was evaluated using analysis of covariance among pre-specified subgroups of mild-moderate and severe baseline disease severity defined by STS (≤5 vs. >5) and EDS (<60 vs. ≥60). Consistency of effect was evaluated by interaction tests. RESULTS: No treatment-subgroup interactions were observed for all end points ( P > .05). The odds of achieving a ≥10-mm improvement in STS for VNS versus VC for patients with baseline STS ≤5 and >5 were 3.4(95% confidence interval, 2.0 to 5.6) and 2.3(1.3 to 4.0) and for EDS of <60 and ≥60 were 3.4(1.9 to 6.1) and 2.5(1.5 to 4.0). Least-squares mean treatment/VC differences in change from baseline in EDS for patients with baseline STS ≤5 or >5 were -7.4(95% confidence interval, -12.5 to -2.4) and -2.8(-8.7 to 3.1); EDS of <60 and ≥60 were -2.9(-8.3 to 2.5) and -8.1(-13.6 to -2.6). CONCLUSIONS: Compared with VC, VNS improved tear production and patient-reported symptoms in patients with dry eye disease, demonstrating consistency of effect regardless of initial presenting severity.

RESUMEN

INTRODUCTION: This study sought to compare the efficacy of OC-01 (varenicline solution) nasal spray for treatment of dry eye disease (DED) in postmenopausal women (PM+) versus women who were not postmenopausal (PM-). METHODS: This was a post hoc subgroup analysis of data integrated from two prior randomized controlled clinical trials, ONSET-1 and ONSET-2. Women randomized to treatment with OC-01 (varenicline solution) nasal spray 0.03 mg or vehicle control (VC) whose self-reported menopausal status (PM+ versus PM-) was known were included. Outcomes included the treatment difference (the OC-01 [varenicline solution] nasal spray change from baseline [CFB] minus VC CFB) in Schirmer test score (STS, mm) with anesthesia and the eye dryness score (EDS) measured on a 100-mm visual analog scale (0 = no discomfort, 100 = maximal discomfort). Least-squares mean treatment differences were derived from analysis of covariance (ANCOVA) models. RESULTS: Overall, 449 female participants in the ONSET-1 and ONSET-2 trials randomized to the OC-01 (varenicline solution) nasal spray 0.03 mg or VC groups were included in this analysis. The treatment-menopausal status interaction terms in the STS and EDS ANCOVA and logistic regression models were not statistically significant (p > 0.05), indicating consistency of treatment effect between the PM- and PM+ groups. The treatment difference in STS was similar in the PM- and PM+ groups (6.7 and 5.5 mm, respectively). The treatment difference in EDS was similar in the PM- and PM+ groups (- 5.5 and - 4.1, respectively). CONCLUSIONS: OC-01 (varenicline solution) nasal spray demonstrated similar efficacy in promoting natural tear production and improving symptoms in both PM- and PM+ groups. As menopausal-related hormonal changes may be associated with more severe DED, these results may support OC-01 (varenicline solution) nasal spray as an effective treatment for DED in women regardless of presenting menopausal status. TRIAL REGISTRATION: Post hoc subgroup analysis of data integrated from ONSET-1 (ClinicalTrials.gov identifier NCT03636061) and ONSET-2 (ClinicalTrials.gov identifier NCT04036292).

RESUMEN

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.
