|Colorectal Cancer||Biological: PolyPEPI1018 CRC Vaccine||Phase 1 Phase 2|
This is a Phase I/II, open-label, single-arm, multicenter study to evaluate the safety, tolerability, immunogenicity and efficacy of a multiple subcutaneous injection of PolyPEPI1018 as an add-on immunotherapy to the standard-of-care maintenance therapy in approximately 15 subjects with metastatic colorectal cancer.
The first part of the study investigates the administration of a single vaccine dose during 12-week follow-up period on an outpatient basis. Screening is performed in parallel with the subject's completion of the standard-of-care first-line treatment and initiation of the standard-of-care maintenance treatment. A single dose of PolyPEPI1018 is administered after the subject initiates the maintenance regimen, and within 3 weeks after the eligibility CT scan was performed. Subjects are monitored every 3 weeks for 12 weeks.
The second part of the study investigates the administration of 3 vaccine doses (Weeks 0, 13, 26) then 12 weeks follow-up on an outpatient basis.

Experimental: PolyPEPI1018 CRC Vaccine
The vaccine contains 6 synthetic peptides mixed with the adjuvant Montanide™. The peptides were selected to induce T cell responses against 12 dominant epitopes from 7 cancer testis antigens (CTAs), which are the most frequently expressed CTAs in colorectal cancer. The 6 peptides were optimized to induce long lasting CRC specific T cell responses.

- Incidence of Treatment Related Adverse Events [ Time Frame: 21 days after each vaccinations ]Occurrence of at least 1 ≥Grade 4 local adverse event (AE) or 1 ≥Grade 3 systemic AE and/or signs/symptoms, lab toxicities, and/or clinical events that is probably or definitely related to study treatment
- Measure T cell responses [ Time Frame: 12 weeks ]To measure vaccine-induce T cell responses in each study subjects
- Prediction of T cell responses [ Time Frame: 21 days ]Predict vaccine-induced T cells in each study subject using the candidate CDx
- Measure objective tumor responses [ Time Frame: 12 weeks ]CT scans will be performed at screening and weeks 6,12 after each vaccination
