Basic Information

• Recruitment Status: UNKNOWN
• Clinical Phase: PHASE2
• Total Enrollment: 70 participants
• Study Classification: INTERVENTIONAL

Brief Summary

This is a prospective, Single arm Phase II trial. Patients were eligible to participate when they had histological or cytological confirmed metastatic colorectal adenocarcinoma Non-MSI(microsatellite instability)-high and TMB(tumor mutational burden)-High.

Patients had to have received at least a second-line standard therapy, including fluoropyrimidine, oxaliplatin, or irinotecan-based regimens and VEGF(vascular endothelial growth factor) inhibitors and to have disease progression within 3 months after the last administration of the last standard therapy or to have stopped such therapy due to unacceptable toxicities. Pre-treatment with anti-EGFR(epidermal growth factor receptor) were mandatory if RAS(Rat sarcoma virus) wild and left side .

Patients who met the eligibility criteria took fruquintinib plus Sintilimab until disease progression, death, unacceptable toxicity, withdrawal of consent by the patient, or decision by the treating physician that discontinuation would be in the patient's best interest. The primary study endpoint was PFS(progression free survival) rate at 6 months.

Eligibility Criteria

Inclusion Criteria

1. Fully understand the study and signed the Informed Consent Form (ICF) out of their own will;

2. Histologically or cytologically diagnosed with metastasis colorectal adenocarcinoma CRC (Phase IV)

3. MSS or MSI-low, MSI was assessed per local guidelines (immunohistochemistry and/or polymerase chain reaction [PCR]) prior to screening. Tumor samples with instability in 0 or 1 marker were identified as microsatellite-stable and MSI-low, respectively.

Failed therapies are defined as the occurance of PD or intolerable toxicities during the treatment or within 3 months after the last dose.

6. Subject must not receive any systematically anti-tumor therapies during the last 4 weeks, and never receive any vascular endothelial growth factor (VEGFR) inhibitor or Immune checkpoint blockade.
