Ocrelizumab for Treating Patients with Primary Progressive Multiple Sclerosis: An Evidence Review Group Perspective of a NICE Single Technology Appraisal

AbstractOcrelizumab is indicated for relapsing remitting and primary progressive multiple sclerosis (RRMS and PPMS, respectively). In an appraisal undertaken by the National Institute for Health and Care Excellence (NICE), the company Roche presented the evidence for ocrelizumab used in patients with PPMS, which came from one single randomised controlled trial (RCT) comparing ocrelizumab versus placebo. Based on results from this trial, the licensed indication was restricted to patients with early PPMS in terms of disease duration and level of disability, and with imaging features characteristic of inflammatory activity. Overall, the Evidence Review Group (ERG) found that the RCT had a low risk of bias. In the post-hoc defined magnetic resonance imaging (MRI) active subgroup, matching the label indication, the risk of confirmed disability progression sustained for 12  weeks (CDP-12) was significantly delayed in the ocrelizumab group compared to placebo. However, considering the same risk with progression sustained for 24 weeks (CDP-24), which was deemed the most clinically relevant, the benefit from ocrelizumab did not reach statistical significance. In the sa me MRI active subgroup, benefits from ocrelizumab on functional outcomes and on health-related quality of life were not clearly demonstrated. A de novo Markov model was used to estimate the cost-effectiveness of ocrelizumab versus best supportive care (BSC) for treating patients with PPMS. Health st ates were defined ...
