A Study Investigating the Efficacy and Safety of LBL-007 Plus Tislelizumab in Combination With Bevacizumab Plus Fluoropyrimidine Versus Bevacizumab Plus Fluoropyrimidine in Participants With Unresectable or Metastatic Colorectal Cancer
Unresectable or Metastatic Microsatellite Stable/Mismatch Repair Proficient Colorectal Cancer
About this trial
This is an interventional treatment trial for Unresectable or Metastatic Microsatellite Stable/Mismatch Repair Proficient Colorectal Cancer focused on measuring Colorectal Cancer, Microsatellite Stable, Mismatch Repair Proficient, Maintenance Therapy
Eligibility Criteria
Inclusion Criteria: Participant must have measurable disease as defined per RECIST version 1.1 Has a histologically confirmed colorectal adenocarcinoma with metastatic or unresectable disease (Stage IV as defined by American Joint Committee on Cancer [AJCC] 8th edition) No prior systemic therapy for colorectal cancer (CRC) in the metastatic setting except for the induction treatment of first-line therapy. Note: Local regional treatment performed during induction systemic treatment is allowed Participants who have completed the first-line induction treatment, with an overall response of stable disease or better Exclusion Criteria: Participants whose disease has become resectable at the investigator's discretion during or after induction treatment are not eligible Induction treatment initiated less than 6 months from completion of any prior neoadjuvant or adjuvant chemotherapy or radiotherapy which occurred later Participants who have been treated with anti-epidermal growth factor receptor (EGFR) antibody in the induction treatment Any prior therapy targeting T-cell stimulation or checkpoint pathways Participants with B-raf proto-oncogene, serine/threonine kinase (BRAF)V600E mutations Have locally or centrally confirmed microsatellite instability-high (MSI-H) by polymerase chain reaction (PCR) method or dMMR by immunohistochemistry (IHC) method Note: Other protocol defined criteria may apply.
