UC Study 3 (8-week induction): TOUCHSTONE is a Phase 2, multicenter, randomized, double-blind, placebo-controlled, parallel-group study to evaluate the clinical efficacy and safety of induction therapy with RPC1063 in 199 patients with moderately to severely active ulcerative colitis. Participants who completed the induction period and were responders at Week 8 continued to receive the same dose of ozanimod during the maintenance period up to Week 32.

  • In controlled and uncontrolled UC studies, the majority (96%) of patients with ALT >3X ULN continued treatment with ZEPOSIA, with values returning to <3X ULN within ~2-4 weeks1
  • The overall discontinuation rate because of elevations in hepatic enzymes was 0.4% in patients treated with ZEPOSIA 0.92 mg and none in patients who received placebo in the controlled UC studies1
  • Patients who develop symptoms suggestive of hepatic dysfunction, such as unexplained nausea, vomiting, abdominal pain, fatigue, anorexia, or jaundice and/or dark urine, should have hepatic enzymes checked, and ZEPOSIA should be discontinued if significant liver injury is confirmed1

In controlled clinical trials with ZEPOSIA, mean lymphocyte counts decreased to approximately 45% of baseline at 3 months (approximate mean blood lymphocyte counts 0.8 x 109/L), and low lymphocyte counts were maintained during treatment with ZEPOSIA.1

  • The proportion of patients treated with ZEPOSIA with lymphocytes less than 0.2 x 109/L was 2.0% in UC Study 1 and Study 3 (phase 2) and 2.3% in UC Study 21
  • These values generally returned to greater than 0.2 x 109/L while patients remained on treatment with ZEPOSIA1
  • After discontinuing treatment, the median time for peripheral blood lymphocytes to return to the normal range was approximately 30 days1
    • Approximately 80% to 90% of patients were in the normal range within 3 months1

    • Most patients (98.3%; n=59) returned to ALC ≥0.2 x 109/L at the time of the analysis; 89.8% returned to ≥0.2 x 109/L while continuing treatment with ZEPOSIA15
  • kPatients may be included in both placebo and ZEPOSIA treatment groups. The total count in the placebo group includes 227 patients who were treated with ZEPOSIA in the induction period and were re-randomized to placebo in the maintenance period of TRUE NORTH.15

  • Safety outcomes were analyzed using descriptive statistics on pooled data from all controlled and uncontrolled UC trials: participants from 32-week TOUCHSTONE trialo (phase 2), 52-week TRUE NORTH trial (phase 3), and the respective open-label extension trials17
  • Median treatment duration in weeks for ZEPOSIA 0.92 mg and placebo was 65.79 and 17.21, respectively17
  • TEAEs identified in the pooled data from all controlled and uncontrolled UC trials were consistent with the controlled UC trials17
  • mTotal patient-years equals the sum of the number of years on study contributed by each patient from time of first dose per treatment group in the pool to last date on study per treatment group in the pool. The algorithm for the last date on study is dependent on patient disposition and whether the patient enrolled into an extension study.17
  • nIncidence rate per 100 patient-years, calculated as number of patients/PY x 100 for specific SOC category or PT subcategory. Analysis was based on the treatment group to which a patient was assigned when the event occurred, including patients who were re-randomized to placebo.17
