• Conditions: Gastric Cancer
• Interventions: Drug: Irinotecan Hydrochloride Liposome Injection

• Registration Number: NCT06499610
• Lead Sponsor: First Affiliated Hospital Xi'an Jiaotong University

Brief Summary

This study is a single-arm, single-center, exploratory clinical study. It is expected that 44 patients with advanced gastric and gastroesophageal junction adenocarcinoma with first-line treatment failure will be included to receive irinotecan liposomes combined with cindilizumab and renvalatinib. The study unit is the First Affiliated Hospital of Xi'an Jiaotong University. The study included screening period (28 days), treatment period (6 cycles), and follow-up period. Subjects signed the informed consent and underwent baseline examination during the screening period, patients meeting the exclusion criteria entered the treatment period, and all subjects completed the protocol to observe safety, tolerability and efficacy. The same subject received only one dosing schedule during the study period. The follow-up period begins after the end of the treatment period.

Detailed Description

This study is an exploratory clinical study. It is expected to include 44 patients with second-line advanced gastric and gastroesophageal junction adenocarcinoma, all treated with irinotecan liposome combined with cindilizumab and lunvatinib.

The dosing regimen of irinotecan liplex injection was 70 mg / m2, cindilizmab 200mg, and valatinib 8-12mg (dose determined by body weight), every 3 weeks, every 2 treatment cycles (every 6 weeks). The subject is scheduled to receive 6 cycles of treatment, or develop intolerable toxicity, or terminate the study for other reasons.

The study included screening period (within 28 days), treatment period (6 cycles) and follow-up period. Subjects signed the informed consent and underwent baseline examination during the screening period, patients meeting the exclusion criteria entered the treatment period, and all subjects completed the protocol to observe safety, tolerability and efficacy. The same subject received only one dosing schedule during the study period. The follow-up period begins after the end of the treatment period.
