PD-1 inhibitor

Sun Yat-sen University · Phase 3 active Small molecule

PD-1 inhibitor is a PD-1 inhibitor Small molecule drug developed by Sun Yat-sen University. It is currently in Phase 3 development for Metastatic non-small cell lung cancer, PD-L1 positive, Metastatic melanoma, Renal cell carcinoma. Also known as: Toripalimab, Camrelizumab, Camrelizumab (AiRuiKa™)、Toripalimab、Pembrolizumab(Keytruda), PD-1 immune checkpoint blockades.

PD-1 inhibitors block the PD-1 receptor on T cells, preventing the PD-L1 ligand from inhibiting T cell activation.

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

Mechanism of action

This blockade allows T cells to recognize and attack cancer cells more effectively. PD-1 inhibitors have been shown to be effective in various types of cancer, including non-small cell lung cancer, melanoma, and kidney cancer. By blocking the PD-1 receptor, PD-1 inhibitors can enhance the body's immune response against cancer cells.
