Active Comparator (erlotinib)

Pfizer · Phase 3 active Small molecule ✓ Verified May 2026

Active Comparator (erlotinib) is a EGFR tyrosine kinase inhibitor Small molecule drug developed by Pfizer. It is currently in Phase 3 development for Metastatic non-small cell lung cancer with EGFR mutations, Locally advanced or metastatic pancreatic cancer (in combination with gemcitabine).

Erlotinib is a tyrosine kinase inhibitor that blocks epidermal growth factor receptor (EGFR) signaling to inhibit cancer cell proliferation.

Erlotinib is a small molecule inhibitor of the epidermal growth factor receptor (EGFR) used to treat EGFR-positive non-small cell lung cancer. It is classified as an INHIBITOR and works by inhibiting the EGFR erbB1.

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

Erlotinib selectively inhibits the intracellular tyrosine kinase domain of EGFR, preventing autophosphorylation and downstream signaling through the MAPK and PI3K/AKT pathways. This leads to cell cycle arrest and apoptosis in EGFR-dependent tumors. It is particularly effective in non-small cell lung cancers harboring activating EGFR mutations.
