Chia Tai Tianqing Pharmaceutical Group Co., Ltd. · Phase 3 active Small molecule ✓ Verified May 2026

TQ-B3139 is a Tyrosine kinase inhibitor Small molecule drug developed by Chia Tai Tianqing Pharmaceutical Group Co., Ltd.. It is currently in Phase 3 development for Solid tumors (specific indications under investigation in Phase 3).

TQ-B3139 is a tyrosine kinase inhibitor that targets multiple kinases involved in cancer cell proliferation and survival.

TQ-B3139 is a small molecule being studied as a potential treatment for various types of cancer, including non-small cell lung cancer and advanced solid tumors. It is being investigated in a clinical trial, NCT04398940, in combination with crizotinib for MET-altered advanced non-small cell lung cancer.

Likelihood of approval
61.3% 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.
Predicted approval windows by jurisdiction (conditional on FDA approval)
Regulator Country Likely year Lag vs FDA
FDA US 2028–2030
EMA EU 2029–2031 +0.7 yr
MHRA GB 2029–2031 +0.7 yr
