Evaluating ozanimod for stable MS patients previously treated with anti-CD20 therapies

Prospective Evaluation of Sequencing From antiCD-20 Therapies to Ozanimod (COAST: CD20 and Ozanimod Sequencing Trial)

Phase 4 Interventional University of Colorado, Denver · NCT06529406

This study is testing if switching to a new medication called ozanimod can be a safe and effective option for stable multiple sclerosis patients who have been using anti-CD20 therapies.

What this trial studies

This multicenter, open-label, prospective study aims to assess the safety and efficacy of ozanimod as a de-escalation therapy for clinically stable patients with relapsing forms of multiple sclerosis who have been treated with anti-CD20 therapies. Over a period of 36 months, the study will compare outcomes of patients transitioning to ozanimod against those who continue their anti-CD20 treatment, utilizing a cohort of at least 500 patients from the Cleveland Clinic and the University of Colorado. Participants must have been stable without new disease activity for at least two years prior to the study.

Who should consider this trial

Good fit: Ideal candidates are adults diagnosed with relapsing forms of MS who have been stable without new inflammatory activity for at least two years and have been on anti-CD20 therapy for a minimum of two years.

Not a fit: Patients who have experienced new inflammatory disease activity or have not been on anti-CD20 therapy for the required duration may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a safer and effective treatment option for patients with relapsing multiple sclerosis by allowing them to transition from anti-CD20 therapies to ozanimod.

How similar studies have performed: While the approach of de-escalating therapy in MS is being explored, this specific evaluation of ozanimod following anti-CD20 therapies is relatively novel and has not been extensively tested in prior studies.
