   Vaccine Administration

   description

   • Phase I: Beginning 9 weeks after completion of chemotherapy, patients receive autologous dendritic cell-adenovirus p53 vaccine subcutaneously (SC) on days 1, 14, and 28. Patients without PD may undergo repeat leukapheresis on day 49. Patients receive vaccine SC again on days 56, 84, and 112 in the absence of disease progression or unacceptable toxicity. Cohorts of 3-6 patients receive escalating doses of autologous dendritic cell-adenovirus p53 vaccine until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which at least 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. • Phase II: Patients receive autologous dendritic cell-adenovirus p53 vaccine at the MTD determined in phase I.

   Rate of Toxicity of the Ad-p53 DC Vaccine

   timeFrame

   4 years

   description

   To evaluate the toxicity of the Ad-p53 dendritic cell (DC) vaccine. While there is no expected toxicity from the Ad-p53 vaccine, there may be unforeseen adverse effects. Patients will be monitored for toxicity, particularly for evidence of autoimmunity. Complete blood counts (CBCs) to monitor for hematologic toxicity, serum creatinine to monitor for renal toxicity, liver function tests (LFTs) to monitor for hepatic toxicity, and a standard clinical toxicity will be performed every other week throughout the period of immunization. In addition, a medical history and physical examination will be performed on a monthly basis.
