NCT ID NCT07606521

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This Phase 1 trial will test PB018, a biosimilar to the MS drug Ocrevus, in 222 people with multiple sclerosis. The study compares how the body processes PB018 versus Ocrevus and checks for safety. Participants will receive either PB018 or Ocrevus, but neither they nor their doctors will know which one. The goal is to see if PB018 behaves similarly in the body, which could lead to a more affordable treatment option.

Active substance

PB018 (a biosimilar to ocrelizumab)

What this could lead to

If successful, PB018 could offer a more affordable treatment option for multiple sclerosis, similar to Ocrevus.

What could go wrong

This is an early Phase 1 trial focused on drug levels and safety, not on effectiveness. The biosimilar may not work as well or have different side effects than Ocrevus.
