Official title
A Phase IIa/IIb Clinical Study of SHR-A1904 in Patients With Previous Systemic Treatment Failure, Positive CLDN18.2 Expression of Locally Advanced Unresectable or Recurrent Metastatic Biliary Tract Cancer
Overview
This is a multicenter, Phase 2 clinical trial to evaluate the efficacy and safety, PK and immunogenicity of SHR-A1904 in patients with advanced or metastatic biliary tract cancer (BTC). Patients will treat with SHR-A1904 until unacceptable toxicity or disease progression.
Interventions
- Drug SHR-A1904 for Injection
SHR-A1904 for injection, different doses.
Primary outcome measures
- Objective response rate (ORR) assessed by investigator. [Time frame: Until progression, assessed up to approximately 1 year.]
Secondary outcome measures (9)
- Disease control rate (DCR) assessed by investigator. [Time frame: Approximately 1 year.]
- Duration of objective tumor response (DoR) assessed by investigator. [Time frame: Approximately 1 year.]
- Time to response (TTR) assessed by investigator. [Time frame: Approximately 1 year.]
- Progression-free survival (PFS) assessed by investigator. [Time frame: Approximately 1 year.]
- Overall survival (OS). [Time frame: Approximately 2 years.]
- Adverse events (AEs). [Time frame: Until study completion, assessed up to approximately 1 year.]
- Serious adverse events (SAEs). [Time frame: Until study completion, assessed up to approximately 1 year.]
- Immunogenicity indicators of SHR-A1904: drug resistant antibody (ADA). [Time frame: Approximately 6 months.]
- Immunogenicity indicators of SHR-A1904: neutralizing antibody (NAb). [Time frame: Approximately 6 months.]
