Официальное название

A Randomized, Open-label, Multicenter Phase III Clinical Study of JMT101 in Combination With Irinotecan in Third-line and Beyond Treatment of Metastatic Colorectal Cancer

Обзор

This is a randomized, open-label, multicenter, phase III clinical study. The aim is to evaluate the efficacy of JMT101 in combination with irinotecan in the third-line and beyond treatment of Metastatic Colorectal Cancer.

Подробное описание

This trial is conducted in patients with refractory metastatic colorectal cancer that has progressed after second-line or higher standard therapy. Eligible patients are randomized into two arms in a 1:1 ratio to receive JMT101 in combination with irinotecan or standard of care until disease progression, unacceptable toxicity or withdrawal of consent by the patient.

Вмешательства

• Препарат JMT101
  JMT101, 6 mg/kg, administered by IV infusion once every two weeks (one treatment cycle is 4 weeks).
• Препарат Irinotecan
  Irinotecan, 180mg/m\^2, administered by IV infusion once every two weeks (one treatment cycle is 4 weeks).
• Препарат Regorafenib
  Regorafenib, 160 mg, taken orally once daily for the first 21 days of each 28-day cycle.
