Clinical Trial Summary

This study was an observational cohort study to investigate the efficacy predictors of fuquinitinib combined with anti-PD-1 monoclonal antibody for third-line treatment and above in Chinese patients with advanced colorectal cancer.

Description:

Patients with histologically confirmed metastatic or unresectable MSS/MSI-L/pMMR colorectal adenocarcinoma refractory to or intolerant of fluorouracil, oxaliplatin and irinotecan based systemic treatment, were enrolled in the study. All patients will receive a third line therapy with fruquintinib and anti-PD-1 antibody. Clinical and radiographic assessment will be performed regularly. Patients will be treated until disease progression, untolerable toxicity or withdrawal of consent.

• Known brain or CNS metastases.

• Patients with any active autoimmune disease or a documented history of autoimmune disease within 4 weeks prior to enrollment.

• Prior allogeneic bone marrow transplantation or prior solid organ transplantation.

• Uncontrolled malignant ascites.

• Clinically significant cardiovascular diseases, including but not limited to acute myocardial infarction, severe / unstable angina pectoris or coronary artery bypass grafting within 6 months before enrollment; Congestive heart failure, New York Heart Association (NYHA) grade > 2; ventricular arrhythmia requiring drug treatment; LVEF (left ventricular ejection fraction) < 50%.
