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).
  • Oncology Phase 3 boost +3.0pp
    Oncology Phase 3 trials have higher approval rates (~61%) than the cross-industry average due to clearer endpoints and FDA oncology pathway.
  • 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.

Mechanism of action

Rituximab targets CD20, a surface antigen expressed on B lymphocytes. By binding to CD20, the antibody facilitates B cell depletion through antibody-dependent cellular cytotoxicity (ADCC), complement-dependent cytotoxicity (CDC), and direct induction of apoptosis. This B cell depletion reduces autoimmune activity in autoimmune diseases and eliminates malignant B cells in lymphomas.
