Introduction: Ozanimod (OZA) is a highly selective sphingosine 1-phosphate (S1P) receptor 1 and 5 modulator approved for the treatment (tx) of moderately to severely active ulcerative colitis (UC) or relapsing multiple sclerosis (RMS). A prior analysis of clinical trial data showed that long-term tx with OZA was well tolerated across 2715 patient-years (PY) of exposure in patients (pts) with UC and 11,732 PY of exposure in pts with RMS. This analysis provides a pooled safety evaluation of OZA in pts with moderately to severely active UC or RMS with additional OZA exposure.
Methods: Pooled data in pts with UC who received OZA in phase 2 (NCT01647516), phase 3 (NCT02435592), and respective open-label extension (OLE; NCT02531126) trials were examined from December 2, 2015, through November 17, 2023. Data in pts with RMS who received OZA in an OLE trial (NCT02576717) after enrolling from phase 1–3 trials were examined from October 16, 2015, through April 7, 2023. Outcomes included treatment-emergent adverse events (TEAEs) and laboratory abnormalities.
Results: Total OZA exposure was 3479 PY in 1158 pts with UC and 12,663 PY in 2494 pts with RMS (16,142 PY in 3652 pts total). TEAEs, serious TEAEs, TEAEs leading to tx discontinuation, and TEAEs of interest in the UC, RMS, and combined UC + RMS populations are reported in the Table. Exposure-adjusted incidence rates (EAIRs) of most TEAEs of interest were low and similar across populations. The most common TEAEs as reported by investigators were lymphopenia (13.0%, EAIR 48.8/1000 PY) and COVID-19 (10.2%, EAIR 36.3/1000 PY) in pts with UC and nasopharyngitis (21.3%, EAIR 49.6/1000 PY) and headache (17.1%, EAIR 38.3/1000 PY) in pts with RMS. Absolute lymphocyte count < 200 cells/µl occurred in 6.8% of pts with UC and 14.8% of pts with RMS during OLE trials but were not temporally associated with serious or opportunistic infections. Most liver enzyme elevations during OLE trials were transient and resolved without tx interruption; no serious hepatic events or Hy’s law cases occurred. There were 5 deaths (0.4%) in UC pts and 15 deaths (0.6%) in RMS pts.
Discussion: Long-term exposure to OZA evaluated over 16,000 PYs in clinical trials continues to be well tolerated in pts with moderately to severely active UC or RMS. These data confirm the established safety profile of OZA, a once-daily oral advanced therapy, with high selectivity for S1P receptors 1 and 5.
