Arm Description

This study will use two dose levels (a starting dose at level 1 and a second dose highest dose at level 2) of the VS-6766 and cetuximab regimen. If participants in group 1 don't experience severe negative side effects to the starting dose of the regimen, then more participants will be assigned to group 2 at a higher dose until the safest/ most tolerable dose is found. If participants show toxic side effects to the first pre-determined dose, the dose will be decreased to the next lower dose level. Group 1/ Dose Level 1: Participants in group 0 will receive the starting dose of study drugs (below): VS-6766 (2.4mg) orally twice a week cetuximab (500mg) via intravenous (IV) needle in vein every 2 weeks During phase 1, VS-6766 and cetuximab will be given in 28-day "cycles" (a period of time when participants receive study drugs). Participants in this portion of the study will receive 12 cycles of VS-6766 and cetuximab.

This study will use two dose levels (a starting dose at level 1 and a second dose highest dose at level 2) of the VS-6766 and cetuximab regimen. If participants in group 1 don't experience severe negative side effects to the starting dose of the regimen, then more participants will be assigned to group 2 at a higher dose until the safest/ most tolerable dose is found. If participants show toxic side effects to the first pre-determined dose, the dose will be decreased to the next lower dose level. Participants in group 2 will receive the second highest dose of study drugs (below): VS-6766 (3.4mg) orally twice a week cetuximab (500mg) via intravenous (IV) needle in vein every 2 weeks During phase 1, VS-6766 and cetuximab will be given in 28-day "cycles" (a period of time when participants receive study drugs). Participants in this portion of the study will receive 12 cycles of VS-6766 and cetuximab.

Participants in this group will received a lower dose of the VS6766 and cetuximab regimen. Inclusion in this group is optional and based on whether the participant reports serious side effects in response to a higher dose of the regimen. If participants are included in this group, they will receive: VS-6766 (2.4mg) orally twice a week cetuximab (400mg) via intravenous (IV) needle in vein every 2 weeks

Participants in this group will received the second lowest dose of the VS6766 and cetuximab regimen. Inclusion in this group is optional and based on whether the participant reports serious side effects in response to a higher dose of the regimen. If participants are included in this group, they will receive: VS-6766 (2.4mg) orally twice a week cetuximab (300mg) via intravenous (IV) needle in vein every 2 weeks

Participants in this arm will help test the efficacy of the VS-6766 and cetuximab dose established in phase 1 of the study. Participants will take the same two drugs ( VS-6766 and cetuximab) at the best tolerated dose that was found during the first phase of the study. Participants in this group will also keep a pill diary. This helps you keep track of when you take your pills. The study team at your doctor's office will show you how to use this diary. Each time you visit the clinic, you must bring the pill diary, any remaining pills, and the pill bottle.

Outcomes

Primary Outcome Measures

Phase I Primary Objective: Maximum Tolerated Dose (MTD) of VS-6766 combined with Cetuximab

Doctors leading the study will find the maximum tolerated dose by assessing the rate of serious side effects (known as "dose limiting toxicities") among participants according to the NCI Common Terminology Criteria (CTCAE) for Adverse Events Version 5.
Phase 2 Primary Objective: Objective Response Rate of Participants Who Take Phase I /MTD Dose of VS-6766 combined with Cetuximab
Objective response rate or participants who take the maximum tolerated dose (MTD) of VS-6766 combined with cetuximab that was established in phase 1 (the dose-finding portion) of the study. The objective response rate (how the participant's cancer responds to the study drugs) will be measured and assessed using the Response Evaluation Criteria in Solid Tumors (RECIST) v1.1.

Secondary Outcome Measures

Phase 1 Objective: The Number of Dose-Limiting Toxicities (Serious Side Effects) Reported Among Participants Taking VS-6766 and Cetuximab
The number of dose-limiting toxicities reported among participants who take VS-6766 and cetuximab at dose levels set by study doctor. Dose-limiting toxicities will be graded/measured using the Common Terminology Criteria for Adverse Events v. 5.0.
Phase 1 Objective: Frequency/ Type of Dose-Limiting Toxicities (Serious Side Effects) Reported Among Participants Taking VS-6766 and Cetuximab
The type of dose-limiting toxicities and their frequency reported among participants who take VS-6766 and cetuximab at dose levels set by study doctor. Dose-limiting toxicities will be graded/measured using the Common Terminology Criteria for Adverse Events v. 5.0.
Phase 2 Objective: Duration of Response
The date at which the participant's earliest best objective status is first noted to be either a complete response or partial response at the earliest date progression is documented, or death if no prior evidence of disease progression. Duration of response will be assessed according to clinical study records and statistical analysis of study data.
Phase 2 Objective: Progression-Free Survival (PFS)
The time from study entry to the first of either disease progression or death from any cause as determined by Response Evaluation In Solid Tumors Criteria 1.1 and statistical analysis of study data (Kaplan-Meier method).
Phase 2 Objective: Two-Month Progression-Free Survival
Two-month progression-free survival defined as the proportion of subjects who did not die nor progress with disease two months after starting therapy as assessed by clinical notes/ study records and statistical analysis of study data.
Phase 2 Objective: Overall Survival
The time from study entry until death from any cause according to clinical notes/study records.
Phase II Objective: Complete Response
Complete response for at least 4 months while on treatment as assessed by clinical notes/study records.
Phase II Objective: Partial Response
Partial response for at least 4 months while on treatment as assessed by clinical notes/study records.
Phase II Objective: Stable Disease

5. Study Description

Brief Summary
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.
Detailed Description
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.

Not have history of retinal pathology or evidence of visible retinal pathology that is considered a risk factor for RVO as measured by tonometry, or other significant ocular pathology, such as anatomical abnormalities that increase the risk for RVO Patients must not have history of corneal erosion (instability of corneal epithelium), corneal degeneration, active or recurrent keratitis, and other forms of serious ocular surface inflammatory conditions. Patients must not have history of retinal degenerative disease. Patient must not have presence of neurosensory retinal detachment, or neovascular macular degeneration on screening ophthalmologic exam. Patients with Impairment of gastrointestinal function or gastrointestinal disease (e.g., active ulcerative disease, uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome, small bowel resection) are excluded. Participants should not have history of bowel perforation or intestinal fistulas in the last 6 months. Participants with current Grade 3 or higher neuropathy are excluded. No prior allogeneic stem cell or solid organ transplantation. Women who are pregnant or breastfeeding are excluded. History of allergic reactions attributed to compounds of chemical or biologic composition similar to those of cetuximab, or if the patient had red meat allergy/tick bite history. The participant is on any medications that conflict with the drugs administered in study. Participants with known or suspected allergy or hypersensitivity to VS-6766 or any of the inactive ingredients which include, but is not limited to, hydroxypropylmethylcellulose, mannitol, magnesium stearate. If the participant has a history of allergic reactions attributed to compounds of chemical or biologic composition similar to those of cetuximab, or if the participant had red meat allergy/tick bite history they must be excluded. Chronic concomitant treatment with strong inhibitors of Cytochrome P450 3A4 (CYP3A4) is not allowed on this study. Patients on strong CYP3A4 inhibitors must discontinue the drug for 14 days prior to registration on the study. See Section 8.1.9 for more information. Chronic concomitant treatment with strong CYP3A4 inducers is not allowed. Patients must discontinue the drug 14 days prior to the start of study treatment. Participants must avoid grapefruit, grapefruit juice, St. John's Wort and other medications (with or without prescriptions), supplements, herbal remedies or foods that are strong inhibitors or inducers of CYP3A4 while on VS-6766.
