What this trial studies

This observational study aims to investigate the wearing-off effects associated with anti-CD20 therapies, specifically ocrelizumab (OCR) and ofatumumab (OMB), in patients with Multiple Sclerosis (MS). Participants will be surveyed at four different time points during their treatment cycles to assess various MS symptoms, including fatigue, mobility, pain, depression, and cognition. The study will also evaluate the impact of worsening MS symptoms on patients' health-related quality of life and work productivity using validated scales. The goal is to better understand the prevalence and nature of these wearing-off effects in MS patients.

Who should consider this trial

Good fit: Ideal candidates are adults aged 21 and older with a self-reported diagnosis of relapsing or secondary progressive Multiple Sclerosis who have been on OCR or OMB for the specified duration.

Not a fit: Patients currently participating in other clinical trials involving MS drugs may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into managing wearing-off effects in MS patients, potentially improving their quality of life.

How similar studies have performed: While the specific focus on wearing-off effects in this context may be novel, there have been other studies examining the efficacy of anti-CD20 therapies in MS, indicating a growing interest in this area.
