Suzhou Suncadia Biopharmaceuticals Co., Ltd. · Phase 3 active Small molecule Under review

SHR-A1811 for Injection is a Bispecific monoclonal antibody; dual checkpoint inhibitor Small molecule drug developed by Suzhou Suncadia Biopharmaceuticals Co., Ltd.. It is currently in Phase 3 development for Advanced or metastatic solid tumors (Phase 3 development). Also known as: SHR-A1811 group.

SHR-A1811 is a bispecific antibody that simultaneously engages two immune checkpoints to enhance anti-tumor T-cell responses.

SHR-A1811 for Injection is being studied in a Phase II clinical trial for the treatment of gynaecological malignancies. The exact mechanism of SHR-A1811 is unknown.

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

SHR-A1811 functions as a bispecific monoclonal antibody designed to target dual immune pathways, likely involving PD-1/PD-L1 and CTLA-4 or similar checkpoint axes. By blocking inhibitory signals on T cells through multiple mechanisms simultaneously, the drug aims to overcome tumor immune evasion and generate more potent anti-tumor immunity than single-checkpoint inhibitors alone.
