A Phase 1b/2 Study of VS-6766 and Cetuximab in Patients With Advanced KRAS Mutated Colorectal Cancer
Doctors leading this study hope to learn about the safety of combining the study drug VS-6766 with another drug called cetuximab in colorectal cancer. This study is for individuals who have advanced colorectal cancer and their cancer has progressed while getting previous treatment or individuals who cannot take/tolerate previous treatments. If you choose to participate, your time in this research will last up to 24 months.
The purpose of this research is to gather information on the safety and effectiveness of
VS-6766 in combination with cetuximab. Doctors leading this study want to find out if
combining two medications (cetuximab and VS-6766) is better or worse than the usual approach
for the treatment of colorectal cancer. The usual approach for treating colorectal cancer
after it progresses involves chemotherapies like Fluorouracil (5-FU), oxaliplatin, irinotecan
and possibly a medication like bevacizumab. This study will instead combine cetuximab and
VS-6766 to find out if the two medications can help people living with advanced colorectal
cancers with certain mutations (differences) called KRAS mutations.

Inclusion Criteria:
- Must be able to show documentation of disease: Participants must have metastatic colorectal adenocarcinoma with kirsten rat sarcoma viral oncogene homolog (KRAS) mutations, detected by any Clinical Laboratory Improvement Amendments-certified method (tumor or ct-DNA), for which curable treatment modalities are not an option.
- Participants with the following KRAS mutations can be included in the study. These eligible KRAS mutations will be confirmed by the Study Chair, Dr. Shergill. Please contact Dr. Shergill for all other mutations that you feel may benefit from this treatment.
- Must have measurable disease per Response Evaluation Criteria in Solid Tumors (RECIST 1.1).
- Must have had progression of disease on 5-FU or capecitabine, oxaliplatin, irinotecan and bevacizumab therapy or must have a scientifically justifiable reason for not having had these therapies prior to trial. If participant has high levels of MicroSatellite Instability (MSI-H), they must have had recommended immunotherapy agent(s) i.e anti- programmed death ligand 1 (L)1 with or without anti-CTLA4 agents.
- Must have not had any treatment with prior MEK (mitogen-activated protein kinase kinase) inhibitor, anti-EGFR (antineoplastic epidermal growth factor receptor), KRAS, SOS1 ( Son of sevenless 1) and SHP2 (Src homology-2 domain-containing protein tyrosine phosphatase-2) inhibitor therapy.
- Participants should not have had chemotherapy, radiotherapy, or major surgery within 2 weeks prior to entering the study.
- Participants should not be receiving any other study agents concurrently with the study drugs.
- Not pregnant and not nursing, because this study involves an investigational agent whose genotoxic, mutagenic and teratogenic effects on the developing fetus and newborn are unknown. Therefore, for women of childbearing potential only, a negative pregnancy test done ≤ 7 days prior to registration is required. Negative serum pregnancy test is required for all female patients of child bearing potential within 7 days of cycle 1 day. All patients should agree to use highly effective method of contraceptive: female patient up to 2 months after 30 days of the last dose and male pts up to 90 days of the last dose.
- Must be 18 years old or older.
- Must have Eastern Cooperative Oncology Group Performance status of 0-1
- Must meet required clinical laboratory values set by study doctor to show participant's health and organ function meets requirements to be in study.
- Must have adequate cardiac function as clinically confirmed by study doctor.
- Participants with human immunodeficiency virus (HIV)-infected who are on effective anti-retroviral therapy with undetectable viral load within 6 months are eligible for this trial.
- For participants with a history of chronic hepatitis B virus infection, the hepatitis B virus (HBV) viral load must be undetectable on suppressive therapy, if indicated.
- Participants with a history of hepatitis C (HCV) infection must have been treated and cured. For participants with HCV infection who are currently on treatment, they are eligible if they have an undetectable HCV viral load.
- Participants with known untreated Central Nervous System (CNS) metastases are excluded. Patients with a history of CNS metastases are permitted to enroll if they have been treated, and systemic steroids have been tapered to physiologic doses (10 milligrams (mg) or less of prednisone or equivalent), and CNS disease has been stable for a minimum of one month on imaging and clinically. Exceptions for participants with asymptomatic sub-centimeter metastases that, in the opinion of the treating investigator, do not require intervention may be possible following discussion and agreement with the overall Study Chair.
Exclusion criteria:
- Participants with uncontrolled intercurrent illness including, but not limited to: ongoing or active infection requiring systemic treatment, symptomatic congestive heart failure, cardiac arrhythmia, psychiatric illness/social situations that would limit compliance with study requirements, hypertension, defined as systolic blood pressure > 160 mmHg despite medical management, myocardial infarction, unstable angina, coronary artery bypass grafting, coronary angioplasty, or stenting < 12 months prior to screening.
- Participants with clinically relevant coronary artery disease or history of myocardial infarction in last 12 months or high risk of uncontrolled arrhythmia or uncontrolled cardiac insufficiency, or those with uncontrolled or poorly controlled hypertension (>180 millimeters of mercury (mmHg) systolic or >130 mmHG diastolic pressures) may not receive cetuximab.
- Participants with history of corrected QT interval (QTc) prolongation, Brugada syndrome, known history of QTc prolongation, or Torsades de Pointes.
