Chemotherapy Combined With Apatinib and PD-1 Antibody
- Conditions
- Gastric Cancer
- Interventions
- Drug: PD-1 antibody, paclitaxel or irinotecan, Apatinib mesylate
- Registration Number
- NCT05025033
- Brief Summary
The effective rate of second-line and later-line single-agent therapy for advanced gastric cancer is limited. This research plan aims to explore whether the combination of drugs can further improve the benefits of second-line and above therapies. Previous studies have shown that there is a significant synergistic effect between chemotherapy and PD-1 monoclonal antibody, or anti-angiogenic TKI drugs and PD-1 monoclonal antibody. This project is planned to be based on the classic chemotherapy drugs irinotecan or paclitaxel, combined with mesylate Apatinib and PD-1 monoclonal antibody, explore the effectiveness and safety of this three-drug combination regimen for the second-line and above treatment of advanced gastric cancer, in order to provide a better late-line treatment plan for patients with advanced gastric cancer.
- Detailed Description
This study is a prospective, single-center, single-arm phase II clinical study, which aims to explore the efficacy of PD-1 antibody combined with apatinib combined with chemotherapy as a second-line and above regimen in the treatment of advanced gastric cancer.The enrolled patients were patients with advanced inoperable gastric cancer or gastroesophageal junction adenocarcinoma who had advanced first-line fluorouracil combined with platinum or advanced second-line paclitaxel and irinotecan, with an ECOG PS of 0-1. Treatment plan: PD-1 antibody: 200mg intravenous drip every 3 weeks; Apatinib 250mg/day; Chemotherapy: Irinotecan 150mg/m2, intravenous drip every 2 weeks, or Paclitaxel 150mg/m2, intravenous drip, once every 3 weeks. An imaging evaluation is performed every 6-8 weeks. Monitor blood routine, blood biochemistry, electrocardiogram, urine routine, thyroid function, heart function according to clinical routine, and record adverse events. Primary observational endpoints: objective effective rate (ORR), progression-free survival time (PFS), secondary observational endpoints: overall survival time (OS), disease control rate (DCR) and safety, and dynamic monitoring of serum biomolecular markers for exploration study .
