A Study of Precemtabart Tocentecan With or Without Bevacizumab Compared to Trifluridine/Tipiracil Plus Bevacizumab in Participants With Previously Treated Metastatic Colorectal Cancer (PROCEADE-CRC-03)

This study aims to address the unmet medical need of participants with metastatic colorectal cancer (mCRC) who have previously been treated with irinotecan, oxaliplatin, a fluoropyrimidine, and bevacizumab, by demonstrating an overall survival prolongation with precemtabart tocentecan (Precem-TcT) as single agent or Precem-TcT in combination with bevacizumab compared to trifluoride/tipiracil (FTD-TPI) plus bevacizumab.

Inclusion Criteria: * Participants with documented histopathological diagnosis of metastatic colorectal cancer, who were intolerant to, or whose disease was refractory to, or progressed after standard systemic therapies and no more than 2 previous systemic treatment regimens in the metastatic setting. * Participants must have received and progressed on no more than 2 previous systemic treatment regimens in the metastatic setting * Eastern Cooperative Oncology Group (ECOG) performance status less than equal to 1 * Participants must be able to swallow oral tablets, and to comply with the study requirements for all scheduled evaluations * Other protocol defined inclusion criteria may apply Exclusion Criteria: * If Adverse Events related to previous therapies have not recovered to less than Grade 1 by National Cancer Institute - Common Terminology Criteria for Adverse Events version 6.0 * Participant has a history of additional malignancy within 3 years before randomization * Participants with known brain metastases * Abdominal fistula, gastrointestinal perforation, or intra-abdominal abscess within the past 6 months prior to randomization * Participants with ileus of more than Grade 1, or chronic inflammatory bowel disease (example ulcerative colitis, Crohn's disease) and/or bowel obstruction, or participants with chronic gastrointestinal disorders that, in the Investigator's opinion, might significantly interfere with proper absorption of the study treatments * Other protocol defined exclusion criteria may apply
