A Phase I Clinical Trial of mTOR Inhibition With Rapamycin for Enhancing Intranodal Dendritic Cell Vaccine Induced Anti-Tumor Immunity In Patients With NY-ESO-1 Expressing Solid Tumors
PRIMARY OBJECTIVES: I. Determine the safety of DC205-NY-ESO-1 vaccine (DEC-205-NY-ESO-1
fusion protein vaccine) with and without sirolimus. Toxicity as defined by the National
Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) Version 4.0.
SECONDARY OBJECTIVES: I. Assess the NY-ESO-1 specific cellular and humoral immunity:
peripheral blood NY-ESO-1 specific cluster of differentiation (CD)8+ and CD4+ T-cells;
peripheral blood NY-ESO-1 specific antibodies; peripheral blood frequency of
CD4+CD25+forkhead box P3 (FOXP3)+ regulatory T-cells. TERTIARY OBJECTIVES: I. Explore time
to disease progression. OUTLINE: Patients undergo standard collection of peripheral white
blood cells via leukapheresis over 90-240 minutes for vaccine preparation. Patients are
assigned sequentially to Cohorts 1a-1d. COHORT 1a: Patients receive intranodal
DEC-205-NY-ESO-1 fusion protein vaccine on days 1, 29, 57, and 113. COHORT 1b: Patients
receive DEC-205-NY-ESO-1 fusion protein vaccine as in Cohort 1a and sirolimus orally (PO) on
days 1-14, 29-42, and 57-70. COHORT 1c: Patients receive DEC-205-NY-ESO-1 fusion protein
vaccine as in Cohort 1a and sirolimus PO on days 15-28, 43-56, and 71-84. COHORT 1d:
Patients receive DEC-205-NY-ESO-1 fusion protein vaccine as in Cohort 1a and sirolimus PO on
days 1-84. COHORT 2: Patients receive treatment as in the Cohort (1a-1d) that is
determined to be safe and produces optimal immunological effects. After completion of study
treatment, patients are followed up at 30 days.
Interventional
Allocation: Non-Randomized, Endpoint Classification: Safety Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment
Safety of the DEC-205-NY-ESO-1 fusion protein vaccine, with and without sirolimus, as evaluated according to the NCI CTCAE scale version 4.0
The safe schedule of the combinatorial regimen is established at the dose before 2/6 patients experience dose-limiting toxicity. Estimated using a one-sided, 95%, exact binomial confidence interval (Clopper-Pearson).
