About

Ocrevus Zunovo implementation, feasibility, acceptability, patient satisfaction, treatment persistence, and impact on MS disease outcomes will be analyzed in this mixed methods study. This study will incorporate clinical data and questionnaire results from MS patients who take Ocrevus Zunovo as well as qualitative interviews with MS patients, family members, and other individuals involved in Ocrevus Zunovo treatment. The purpose of this study is to synthesize implementation strategies that improve patient access to high-efficacy MS therapies in real-world settings.

Full description

Patients with MS who are clinically seen at the Northwestern Memorial Hospital system and are eligible for Ocrevus Zunovo (OZ) initiation may enroll in this study. OZ will be administered by the clinical infusion center.

The study will enroll 50 OZ-treated MS patients over the course of 15-18 months, at approximately 4 patients per month. Participants will each be surveyed and followed at three main timepoints: (1) enrollment, as close as possible to the time of first OZ dosing, (2) 6 months of follow up, and (3) 12 months of follow up.

The study will also conduct 100 semi-structured interviews, where facilitators and barriers will be recorded by patients, relevant stakeholders in their care and insurance billing, administrators, and clinical staff members.
