Ocrelizumab IV

Hoffmann-La Roche · Phase 3 active Small molecule Under review Quality 0/100

Ocrelizumab IV is a CD20-targeting monoclonal antibody Small molecule drug developed by Hoffmann-La Roche. It is currently in Phase 3 development for Relapsing-remitting multiple sclerosis (RRMS), Primary progressive multiple sclerosis (PPMS). Also known as: RO4964913.

Ocrelizumab is a monoclonal antibody that depletes B cells by binding to CD20, reducing autoimmune-mediated inflammation.

Ocrelizumab IV is an antibody that binds to the B-lymphocyte antigen CD20, classified as a BINDING AGENT. It is used to treat conditions such as Relapsing-Remitting Multiple Sclerosis, Primary Progressive Multiple Sclerosis, and Rheumatoid Arthritis, among others.

Likelihood of approval
62.3% vs 58.3% industry baseline
If approved by FDA: likely 2028–2030
Steps remaining: NDA/BLA submission
Confidence: High
Why this estimate
  • Baseline phase 3 → approval rate +58.3pp
    Industry-wide phase 3 drugs reach approval ~58.3% of the time (BIO/Informa 2023 industry benchmark across all therapeutic areas).
  • Immunology slight uplift +1.0pp
    Mature endpoint landscape (ACR, DAS28, PASI) makes immunology approvals slightly more predictable.
  • Big-pharma sponsor +3.0pp
    Hoffmann-La Roche is a top-20 pharma sponsor — historical approval rates run ~3pp above average due to scale, regulatory experience, and trial-design quality.
Predicted approval windows by jurisdiction (conditional on FDA approval)

Mechanism of action

Ocrelizumab targets CD20, a surface antigen expressed on B cells, leading to B cell depletion through antibody-dependent cellular cytotoxicity (ADCC) and direct induction of apoptosis. By eliminating B cells, the drug reduces the production of autoimmune antibodies and pro-inflammatory cytokines, thereby suppressing the autoimmune response underlying multiple sclerosis and other B cell-driven conditions.
