FOLFOX and Bevacizumab in Combination With Botensilimab and Balstilimab (3B-FOLFOX) for the Treatment of Microsatellite Stable (MSS) Metastatic Colorectal Cancer (NCT05627635)
🩺 Plain-English Summary (8th-Grade Level)
This phase I/II trial tests the safety, side effects, best dose, and efficacy of FOLFOX and bevacizumab in combination with botensilimab and balstilimab (3B-FOLFOX) in treating patients with microsatellite stable (MSS) colorectal cancer that has spread from where it first started (primary site) to other places in the body (metastatic). Chemotherapy drugs, such as FOLFOX, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Bevacizumab is in a class of medications called antiangiogenic agents. It works by stopping the formation of blood vessels that bring oxygen and nutrients to tumor. This may slow the growth and spread of tumor. Balstilimab and botensilimab are in a class of medications called monoclonal antibodies. They bind to proteins, called PD-L1 and CTLA-4, which is found on some types of tumor cells. These PD-1 and CTLA-4 proteins are known to affect the body's defense mechanism to identify and fight against tumor cells. The combination of these drugs may lead to improved disease control and outcomes in patients with MSS metastatic colorectal cancer.

Usually NOT eligible if any of the following apply:
- Exclusion Criteria:
- Prior immunotherapy
- Patients with a condition requiring systemic treatment with either corticosteroids (\> 10 mg daily prednisone equivalent) within 14 days or another immunosuppressive medication within 30 days of the first dose of study treatment. Inhaled or topical steroids, and adrenal replacement steroid doses \> 10 mg daily prednisone equivalent, are permitted in the absence of active autoimmune disease

- Active autoimmune disease or history of autoimmune disease that required systemic treatment within 2 years before starting treatment, i.e., with use of disease-modifying agents or immunosuppressive drugs
- Uncontrolled hypertension, defined as systolic blood pressure (SBP) \>150, diastolic blood pressure (DBP) \> 90
- History of acute thrombotic venous events in the last 30 days before enrollment. If within 30 days, the patient should be on anticoagulants and without symptoms
- Clinically significant (i.e., active) cardiovascular disease: cerebral vascular accident/stroke or myocardial infarction within 12 months of enrollment, unstable angina, congestive heart failure (New York Heart Association class \>= III), or serious uncontrolled cardiac arrhythmia requiring medication
- Obstructive bowel symptoms related to unresected primary or carcinomatosis
- Any persistent toxicities (Common Terminology Criteria for Adverse Events \[CTCAE\] grade \>= 2) from prior cancer therapy, excluding endocrinopathies stable on medication, stable neuropathy that is grade 1 or less, and alopecia
