A Vaccine (PolyPEPI1018 Vaccine) and TAS-102 for the Treatment of Metastatic Colorectal Cancer

Brief Summary
This phase Ib trial studies the safety and side effects of a vaccine (PolyPEPI1018 vaccine) in combination with TAS-102 in treating patients with colorectal that has spread to other parts of the body (metastatic). PolyPEPI1018 peptide vaccine is used to immunize against proteins present on the surface of tumor cells. This vaccine can activate the body's immune cells, called T cells. T cells fight infections and can also kill cancer cells. TAS-102 may help block the formation of growths that may become cancer. Giving PolyPEPI1018 and TAS-102 may kill more tumor cells in patients with metastatic colorectal cancer.

Outcome Measures
Primary Outcomes (1)
Incidence of adverse events (AE)
The occurrence of at least 1 Grade 4 local AE or 1 Grade 3+ systemic AE during the first cycle of treatment. Evaluable patients are patients who are eligible, consented, received at least 50% of their expected cycle 1 trifluridine and tipiracil hydrochloride treatment, and received at least one dose of the PolyPEPI1018 Vaccine. The final local or systemic AE rate point estimate and corresponding 95% confidence interval will be reported.
Up to 1 year
Secondary Outcomes (4)
Overall response rate (ORR)
Up to 1 year
Duration of response (DoR)
Up to 1 year
Overall survival (OS)
From registration to death from any cause, assessed up to 1 year
Progression free survival (PFS)
From registration to progression or death from any cause, whichever happens first, assessed up to 1 year
Study Arms (1)
Treatment (PolyPEPI1018, TAS-102)
EXPERIMENTALPatients receive PolyPEPI1018 SC at 4 injection sites on days 1 and 15 and trifluridine and tipiracil hydrochloride PO BID on days 1-5 and 8-15. Treatment repeats every 28 days for up to 7 cycles in the absence of disease progression or unacceptable toxicity.
