PF-02341066

Pfizer · Phase 3 active Small molecule ✓ Verified Jun 2026

PF-02341066 is a ALK/ROS1 tyrosine kinase inhibitor Small molecule drug developed by Pfizer. It is currently in Phase 3 development for ALK-positive non-small cell lung cancer, ROS1-positive non-small cell lung cancer. Also known as: cMET inhibitor, Crizotinib, crizotinib.

PF-02341066 is a tyrosine kinase inhibitor that targets ALK (anaplastic lymphoma kinase) and ROS1 to block aberrant signaling in cancer cells.

PF-02341066 is a medication studied in clinical trials for the treatment of Non Small Cell Lung Cancer, Lung Cancer, Adenocarcinoma, NSCLC, and Carcinoma. It is a C-MET inhibitor, as indicated by its use in combination with a PAN-HER inhibitor in a Phase 1 clinical trial.

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
    Pfizer 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

The drug inhibits ALK and ROS1 receptor tyrosine kinases, which are frequently dysregulated in certain cancers through gene fusions or mutations. By blocking these kinases, PF-02341066 prevents downstream signaling that drives cancer cell proliferation and survival. This mechanism is particularly effective in ALK-positive and ROS1-positive non-small cell lung cancers.
