Phase 2
- Conditions
- Advanced Pancreatic Cancer
- Interventions
- Registration Number
- NCT05298020
- Brief Summary
This is a single-arm, open-label, exploratory study to evaluate efficacy and safety of envafolimab combined with endostar and nab-paclitaxel plus gemcitabine for first-line treatment of advanced pancreatic cancer.
- Detailed Description
This study is a prospective, open-label, single-arm, exploratory clinical study.
Recruited 20 subjects who met the inclusion criteria and received Endostar+Envofolimab+Nab-paclitaxel/Gemcitabine (AG regimen) chemotherapy according to the study plan. Treatment duration and dose can be adjusted according to patient tolerance until disease progression or intolerable toxicity, or other conditions determined by the investigator. During the trial, the efficacy indicators and safety indicators were observed.
