A Study to Evaluate the Efficacy of VVD-133214 in Combination With Pembrolizumab Compared With Pembrolizumab Alone in Participants With Advanced Cancer of the Colon or Rectum
Eastern Cooperative Oncology Group (ECOG) performance-status score of 0 or 1
Have a known microsatellite instability (MSI) and/or deficient mismatch repair (dMMR) tumor status confirmed per local standard of care (SoC), and have histologically or cytologically documented advanced (unresectable and/or metastatic) colorectal adenocarcinoma (CRC)
No prior systemic treatment for metastatic disease and not amenable to curative resection
Participants must have documented MSI and/or dMMR tumor status determined as part of the routine diagnostic workup in a certified laboratory
Availability of formaldehyde-fixed paraffin-embedded (FFPE) archival tumor tissue for submission to Sponsor/central laboratory for retrospective central testing including a copy of a redacted pathology report if available
Presence of measurable disease according to RECIST v1.1
Adequate hematologic and end-organ function, defined using laboratory results obtained within 14 days prior to first dose of study treatment
Females of childbearing potential must have negative serum pregnancy test before starting study treatment
You may not be if
Prior systemic treatment for advanced CRC. Participants may have received prior adjuvant chemotherapy as long as disease progression occurred at least 12 months after the last dose of adjuvant treatment
Prior treatment with adjuvant immunotherapy (e.g., anti-PD-1, anti-PD-L1, anti-PD-L2 agent, or anti-CTLA-4 agent, or any other antibody or drug specifically targeting T cell co-stimulation or immune checkpoint pathways, including prior therapy with anti-tumor vaccines or other immuno-stimulatory antitumor agents, etc.)
Known active or uncontrolled central nervous system (CNS) or brain metastases (progressing or requiring anticonvulsants or corticosteroids for symptomatic control) and/or carcinomatous meningitis
Patients with active or history of autoimmune disease or immune deficiency that has required treatment in past 2 years
History of malignancy other than CRC, within 5 years prior to screening. Participants with Lynch syndrome are not excluded.
Participants requiring treatment with systemic immunosuppressive medication (such as corticosteroids) within 2 weeks prior to initiation of study treatment, or anticipation of need for systemic immunosuppressive medication during study treatment
Participants with active hepatitis B, hepatitis C or HIV
Participants with known Werner Syndrome (WRN)
Prior treatment with any WRN helicase inhibitor
