简要总结
Dose escalation clinical trial: To explore the dose limiting toxicity (DLT) of irinotecan liposome injection combined with oxaliplatin +5-FU/LV+ bevacizumab in first-line treatment of patients with advanced metastatic colorectal cancer, and to estimate the maximum tolerated dose (MTD) of combined administration.
Expansion clinical trial: To evaluate the safety and efficacy of irinotecan liposome injection combined with oxaliplatin +5-FU/LV+ bevacizumab or cetuximab in first-line treatment of patients with advanced metastatic colorectal cancer. Exploratory analysis of ctDNA changes and genetic mutations in patients at baseline.
详细描述
This is a dose escalation and expansion study to evaluate the safety and efficacy of irinotecan liposome injection in patients with first-line treatment for metastatic colorectal cancer. In the dose escalation phase, patients will be treated with a combination regimen of irinotecan liposome injection at doses of 60mg/m2, 70mg/m2, and 80mg/m2, and 9 to 18 eligible patients are expected to be enrolled. In the expansion phase, approximately 60 patients will receive combination therapy with irinotecan liposome RP2D dose and exploratory analysis of genetic mutations at baseline and ctDNA changes during treatment.
