Summary

The purpose of this study is to evaluate the safety and effectiveness of Tumor Associated Peptide Antigen (TAPA) pulsed dendritic cell (DC) vaccines in the treatment of progressive and/or refractory hematologic malignancies (HM). We hypothesize that treatment of patients with relapsed and/or refractory HM, without available potentially curative treatment options, and whose neoplastic cells express at least one (1) TAPA of a defined panel of TAPAs, using low-dose cyclophosphamide (CYP) followed by an autologous, monocyte-derived, TAPA-pulsed DC vaccine and low-dose granulocyte macrophage colony stimulating factor (GM-CSF), will result in TAPA-specific T-cell responses without significant toxicities. We also hypothesize CD4+ T-cell and CD8+ T-cell responses generated against specific TAPAs may translate into clinical antitumor activity.

Conditions

Interventions

BIOLOGICAL

TAPA-pulsed DC vaccine

A cycle of low-dose cyclophosphamide (100mg/day) by mouth for 5 days starting seven 7 days prior to the DC vaccine cycle to reduce Treg activity. Low-dose cyclophosphamide will be taken every 14 days for six 6 cycles. A total of 6 vaccines containing 1 x 10\^7 TAPA-pulsed DC will be administered SQ every 14 days. The DC vaccine is given on Day 1 of the DCV cycle plus low-dose GM-CSF 50mcg/day SQ x 5 days (Day 1 to Day 4). GM-CSF is administered for 5 days to increase monocyte production and dendritic cell precursors to optimize immune responses.
