Experimental: Vigil™
Patients will receive 1 x 10^7 cells (Group A) via intradermal injection for a minimum of 4 doses and a maximum of 12 doses (vaccine) starting post-surgery Week 4-8 (C1W1D1) and continuing C1W3D1, C2W3D1, then every 28 days.

Biological: Vigil™ Vaccine
Patients will receive 1 x 10^7 cells (Group A) or placebo (Group B) via intradermal injection for a minimum of 5 doses and a maximum of 12 doses starting post-surgery Week 4-8 (C1W1D1) and continuing C1W3D1, C2W3D1, then every 28 days.

- Immune Analysis in Tumor Biopsy and Blood (Part 1) [ Time Frame: Up to 12 months ]To evaluate and correlate Tumor Infiltrating Lymphocytes (TIL) in initial excised tumor and Enzyme-Linked ImmunoSorbent Spot (ELISPOT) responses to Vigil™ vaccine in blood of patients with CLM.
- Percent of Patients Who Progressed After Treatment (Part 2) [ Time Frame: 24 months ]Response rate will also be evaluated in this study using the Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST) (unidimensional measurement) of the tumor lesions are used in the RECIST criteria.The response in patients with measurable disease will be reported using standard outcome measures for clinical trials: complete response (CR), partial response (PR), stable disease (SD) and progressive disease (PD). Any response to treatment (either PR or CR) requires two confirmatory staging at least 4 weeks apart. Patients will be evaluable for tumor response if measurable disease is present.
- Percent of Patients Who Survived After Treatment (Part 2) [ Time Frame: 24 months ]To determine and compare the overall survival rate in patients with CLM following resection +/- ablation with curative intent treated with sandwich or adjuvant chemotherapy and Vigil™ vaccine versus sandwich or adjuvant chemotherapy and placebo and compare with historical data.
- Enzyme-Linked ImmunoSorbent Spot (ELISPOT) (Part 1) [ Time Frame: Baseline, End of Treatment (30 days after last dose) up to 12 months ]To determine if subjects will have a positive (defined as >10 ELISPOTS from baseline) immune response to Vigil. Blood was collected to compare ELISPOT results from baseline until 30 days after last dose.
- Number of Alive Subjects (Part 1) [ Time Frame: 24 Months ]For Part 1, this was to determine the overall survival rate in patients with CLM following resection +/= ablation with curative intent treated with adjuvant chemotherapy and Vigil™ by following these patients up to 24 months.
