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).
  • 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

This monoclonal antibody binds to the extracellular domain of the HER2/neu receptor, preventing it from interacting with its ligands and triggering downstream signaling pathways that promote cell growth and survival. By inhibiting these pathways, trastuzumab IV can help slow or stop the growth of HER2-positive cancer cells.
