About

This is an prospective, single-center, single-arm, Simon's two-stage design, phase IIa study for advanced/metastatic colorectal cancer (CRC) who had failed or were intolerant to standard treatment. This study aims to evaluate the safety and efficacy of mFOLFOX6 combined with dalpiciclib (SHR6390) in the treatment of advanced/metastatic colorectal cancer.

Full description

1. Primary study end point:

   To evaluate the safety and objective response rate (ORR) of mFOLFOX6 combined with dalpiciclib (SHR6390) in patients with advanced/metastatic colorectal cancer who had failed or were intolerant to standard treatment.

2. Secondary study end Point:

To evaluate the progression-free survival (PFS) and overall survival (OS) of mFOLFOX6 combined with dalpiciclib (SHR6390) in patients with advanced/metastatic colorectal cancer who had failed or were intolerant to standard treatment.

Enrollment: 18 estimated patients

Sex: All

Ages: 18 to 70 years old
