Outcome Measures

Primary Outcomes (2)

  • Changes in Numbers of Peptide-specific CD8+ T Cells (Post-vaccine Immune Response)

    Assessment of cellular immune activity may occur via the application of flow cytometry. Numbers of peptide-specific CD8+ T cells will be measured by flow cytometric-based intracellular cytokine or tetramer staining. Flow cytometric assays will include an examination of the influence of immunotherapy on the ability of subject T cells to exhibit phenotypic markers associated with cytolytic potential (e.g. IFN-y, IL-2, TNF-alpha, Granzyme B) after short-term stimulation by mutated peptide and p-HLA multimer staining. PBMC responses against a pool of known antigenic Cytomegalovirus, Epstein Barr Virus and Influenza epitopes will be evaluated in order to track general cellular immune competence during the study.

    Screening, Day 1, Day 43, Day 85. Also at following timepoints, which will vary by subject: 7-14 days after last vaccine; 30 days after last vaccine; every 3 months beginning 6 months since first vaccine until month 12.

  • Adverse Events Experienced by Subjects (i.e. Safety of DC Vaccine in Subjects With Surgically Resected Hypermutated CRC)

    Number of subjects who experienced adverse events. Detailed adverse event data is presented in the AE section.

Secondary Outcomes (1)

  • Percentage of CD8+ Cells in Primary Tumor Tissue

Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Pathologically-confirmed stage I and II hypermutated colorectal cancer (CRC)
  • Surgically resected disease
  • Male or female patients 18+ years of age
  • ECOG performance status 0-1
