Efficacy was assessed using integrated data from ONSET-1 and ONSET-2 [vehicle control (VC), n=294; OC-01 VNS 0.03 mg, n=308]. Subgroups included age (⤠55, 56â 65, > 65 years), gender (male, female), race (White, Black or African American), ethnicity (Hispanic or Latino, Not Hispanic or Latino), and artificial tear use (yes, no). Analysis of covariance models, with the covariates treatment, study site, and baseline severity measures, were used to calculate treatmentâVC differences. Consistency of effect among subgroups was evaluated by conducting interaction tests.Results: Consistency of treatment effect across subgroups was observed for all endpoints, with P value for all treatmentâsubgroup interaction terms > 0.05. For % of patients with ⥠10mm improvement in STS and least squares (LS) mean change from baseline in STS and EDS, there was improvement in tear production across demographic group categories. Artificial tear use did not change STS or EDS outcomes with OC-01 VNS.Conclusion: OC-01 VNS improved tear production and patient-reported symptom outcomes across a broad range of patients by age, gender, race, and ethnicity, and regardless of artificial tear use status at baseline. OC-01 VNS demonstrated a consistent benefit across an extensive range of patients with dry eye disease.Keywords: bioactivation, dry eye disease, nicotinic acetylcholine receptor, tear production, varenicline nasal spray more...
