Patients must have Stage II/Stage III rectal cancer or Stage II (high risk)/Stage III colon cancer per American Joint Committee on Cancer 2017 that has been surgically totally resected (R0 confirmed by pathology report). Stage II (high risk) colon cancer is defined as Stage II disease with any of the following risk factors for recurrence:
Patients must have detectable ctDNA prior to start of adjuvant chemotherapy (AdCTx) (except for the Biomarker Cohort).
• ctDNA assay must be performed through this trial or study BNT000-001 ctDNA screening protocol.
Patients must have an Eastern Cooperative Oncology Group Performance Status of 0-1.
Patients must have adequate hematologic, bone marrow and organ function as defined by the protocol.
Adequate tumor material in formalin-fixed paraffin embedded blocks or as sectioned tissue (only upon approval by sponsor) must be available (as described in the laboratory manual).
The patient has started a standard of care AdCTx preferably within 8 weeks but no later than 10 weeks post-surgery and has completed at least 3 months of treatment of a 3- or a 6-month course of chemotherapy (including rest days).
Exclusion criteria
Patients with uncontrolled intercurrent illness as defined by the protocol.
Diagnosed microsatellite instability high tumors.
Prior therapy with any of the following:
Toxicities from previous anti-cancer therapies that have not resolved to baseline levels or to Grade 1 or less except for alopecia and peripheral neuropathy.
Patients who developed metastatic disease during screening/receiving standard of care treatment (not applicable for Exploratory Cohort).
Patients with known past or current malignancy other than inclusion diagnosis, except for:
Patients with known allergies, hypersensitivity, or intolerance to RO7198457 or its excipients.
Patients who had major surgery (e.g., surgery requiring general anesthesia) within 4 weeks before screening, or will not have fully recovered from surgery, or have surgery planned during the time the patient are expected to participate in the trial.
Patients with positive serology for hepatitis B (unless immune due to vaccination or resolved natural infection or unless passive immunization due to immunoglobulin therapy):
Active Hepatitis C virus (HCV) infection; patients who have completed curative antiviral treatment with HCV viral load below the limit of quantification are allowed.
Patients who have a history of human immunodeficiency virus (HIV) antibody positivity, or tests positive for HIV at screening.
Patients who have had prior splenectomy.
