PRIMARY OBJECTIVES:
I. To establish whether the combination of peptide-loaded autologous alpha dendritic cell (DC)1 vaccines and tumor-selective chemokine modulation with interferon (IFN) alpha, rintatolimod, and celecoxib improves the overall survival (OS) in histocompatibility antigen (HLA)-A2+ subjects with chemo-refractory metastatic colorectal cancer (mCRC) compared to the historical control of the best supportive care.
SECONDARY OBJECTIVES:
I. To estimate the immune-related objective response rate (irORR) and the immune-related progression-free survival (irPFS) in HLA-A2+ subjects with chemo-refractory mCRC treated with the combination of peptide-loaded autologous alpha DC1 vaccines and tumor-selective chemokine modulation with celecoxib, IFN alpha and rintatolimod.
II. To estimate the changes of cluster of differentiation (CD)8+ tumor infiltrating lymphocytes (CTLs) in paired tumor tissues collected at pre- and post-treatment.
III. To estimate the changes of tumor microenvironment in paired tumor tissues collected at pre- and post-treatment.
OUTLINE:
Patients receive celecoxib orally (PO) once daily (QD), recombinant interferon alfa-2b (IFN alpha-2b) intravenously (IV) over 20 minutes, and rintatolimod IV over 120 to 150 minutes on days 1-3. Beginning course 2, patients also receive alpha-type-1-polarized dendritic cell vaccine (alpha DC1) intranodally (IN) and intradermally (ID) on day 1. Courses repeat every 21 days for up to 4 courses in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3 months for up to 3 years.
