Ocrevus has some effect at reducing disability progression within about 12 weeks; however, it may take at least 6 months or possibly longer for the full effects to be seen. Trials of up to 96 weeks (almost 2 years) duration have shown that:
- The number of patients with disability progression was significantly lower with Ocrevus compared with REBIF (interferon beta-1a) at 12 weeks (9.1% of those prescribed Ocrevus vs. 13.6% of those prescribed REBIF), and 24 weeks (6.9% vs. 10.5%)
- 82% to 83% of people taking Ocrevus were relapse-free after 24 weeks compared to 71% to 72% of those taking REBIF
- People taking Ocrevus had 46% to 47% fewer relapses a year than people prescribed REBIF.
