Switching to Ozanimod for Relapsing Remitting Multiple Sclerosis

SWITCH - ITA A Multicentre, Single Country, Prospective Non Interventional Observational Study to Describe the Switching From a First- or Second-line Disease Modifying Therapy (DMT) to Ozanimod, in Relapsing Remitting Multiple Sclerosis (RRMS) Patients Treated According to Clinical Practice.

Bristol-Myers Squibb · NCT05658601

This study looks at why people with relapsing remitting multiple sclerosis switch to a new medication called ozanimod and how it affects their condition.

What this trial studies

This study aims to describe the reasons and circumstances under which patients with Relapsing Remitting Multiple Sclerosis (RRMS) switch from their current first or second-line Disease Modifying Therapy (DMT) to ozanimod. Participants must have made this switch between 4 and 12 weeks prior to enrollment and have undergone an MRI within the last three months. The study will collect data on therapy changes and disease progression to better understand the impact of ozanimod in this patient population.

Who should consider this trial

Good fit: Ideal candidates for this study are patients diagnosed with RRMS who have recently switched to ozanimod from another DMT.

Not a fit: Patients with clinical forms of MS other than RRMS or those who have contraindications to ozanimod will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into the effectiveness and reasons for switching to ozanimod, potentially improving treatment strategies for RRMS patients.

How similar studies have performed: While there may be studies on DMT switching, this specific observational approach focusing on ozanimod is relatively novel.
