Cetuximab/Erbitux

Bristol-Myers Squibb · Phase 3 active Small molecule ✓ Verified May 2026

Cetuximab/Erbitux is a EGFR inhibitor (monoclonal antibody) Small molecule drug developed by Bristol-Myers Squibb. It is currently in Phase 3 development for Metastatic colorectal cancer (KRAS wild-type), Head and neck squamous cell carcinoma, Non-small cell lung cancer (EGFR-expressing).

Cetuximab is a monoclonal antibody that blocks the epidermal growth factor receptor (EGFR) on cancer cells, preventing tumor growth and survival signals.

Cetuximab, also known as Erbitux, is an antibody that targets and inhibits the epidermal growth factor receptor (EGFR), a protein involved in cell growth and division. It is used to treat various types of cancer, including squamous cell carcinoma of the head and neck, non-small-cell lung carcinoma, and other lung cancers.

64.3% 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).
  • 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
    Bristol-Myers Squibb 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

Cetuximab binds to EGFR with high affinity, competitively inhibiting ligand binding and preventing receptor activation. This blocks downstream signaling pathways (MAPK and PI3K/AKT) that drive cell proliferation and survival. The antibody also recruits immune cells to mediate antibody-dependent cellular cytotoxicity (ADCC) against EGFR-expressing tumor cells.
