Study Description

Brief Summary:

The study will evaluate the efficacy and safety of envelizumab in combination with sovalteinib in the treatment of treated bile duct cancer, and explore treatment options to improve patient survival, while the study will attempt to explore the characteristics of the population benefiting from the treatment, and construct a preliminary efficacy prediction model by detecting markers in blood to provide a theoretical basis for implementing precise treatment.

Outcome Measures

Primary Outcome Measures :

1. ORR [ Time Frame: through disease progression, an average of 6 months ]
   Proportion of patients whose tumors shrink by a certain amount and remain for a certain period of time

Secondary Outcome Measures :

1. DoR [ Time Frame: through disease progression, an average of 6 months ]
   The time from the first evaluation of the tumor as CR or PR to the first evaluation of PD (Progressive Disease) or death from any cause
2. DCR [ Time Frame: through disease progression, an average of 6 months ]
   Time from the start of the first evaluation of the tumor as CR, PR or SD to the first evaluation of PD (Progressive Disease) or death from any cause
3. PFS [ Time Frame: through disease progression, an average of 1 6 months ]
   Time from treatment initiation to first tumor progression or death
4. OS [ Time Frame: through patient death, an average of 1 year ]
   Time from the start of treatment to death from any cause

Exclusion Criteria:
