Background Older adults with ulcerative colitis (UC) have unique treatment challenges. Ozanimod is approved for the treatment of moderately to severely active UC in adults based on the phase 3 True North (TN) study results. Here, we analyzed the impact of patient age on ozanimod safety and efficacy in TN and during the open-label extension (OLE). Methods Patients were stratified by age at TN baseline: <40, 40 to 60, and >60 years (cutoff: 75 years). Safety was evaluated in all patients during TN and the OLE; efficacy was assessed at weeks 10 and 52 in TN and up to OLE week 190 in patients who entered as TN week 52 ozanimod clinical responders. Results Of 1012 patients analyzed, 492 were <40 years of age, 404 were 40 to 60 years of age, and 116 were >60 years of age. Infection, malignancy, cardiac events, and macular edema were low throughout TN across all ages. Exposure-adjusted incidence rates (EAIRs) of opportunistic and serious infections increased with age during the OLE. Patients ≥40 years of age had higher hypertension EAIRs than those <40 years of age, but EAIRs of other cardiovascular TEAEs were low. No cases of progressive multifocal leukoencephalopathy occurred over 242 weeks of ozanimod exposure. Efficacy rates for evaluated clinical and mucosal endpoints at weeks 10 and 52 with ozanimod were generally consistent across age groups with the overall population; similar trends were observed in the OLE. Conclusions Ozanimod safety was similar and efficacy was generally comparable across age groups, although statistical significance vs placebo was not achieved in patients >60 years of age.
