IL15 Dendritic Cell Vaccine for Patients With Resected Stage III (A, B or C) or Stage IV Melanoma

Phase 1

Completed

• Conditions: Malignant Melanoma Stage IV; Malignant Melanoma Stage III
• Interventions: Biological: IL15-DC Vaccine

• Registration Number: NCT01189383
• Lead Sponsor: Baylor Research Institute

Brief Summary

The purpose of the study is to gather data on feasibility as well as immune and clinical efficacy of of a dendritic cell vaccine using IL15 in patients with resected stage III or stage IV melanoma

Detailed Description

IL15 is a T cell growth factor that pre-clinical data overwhelmingly suggests could have a very important role in cancer immunotherapy. A desirable property for a dendritic cell vaccine directed against cancer is the ability to efficiently prime naïve, tumor associated antigen specific T cells into potent CTLs. Results of studies in healthy volunteers have shown that IL15 DCs are particularly efficient at priming functional melanoma specific CD8+ T cells. The use of IL15 in the manufacture of the DC vaccine could result in an improved immunotherapy product.

Arm && Interventions

Group	Intervention	Description
IL15-DC Vaccine	IL15-DC Vaccine	Approximately 9 x 10\^6 DCs will be injected (subcutaneously)total per vaccination visit. Patients will receive four vaccinations at weeks 0, 4, 8 and 12.At each scheduled vaccination the patient will receive a total of 3 injections, i.e., 3 mL injections at each of 3 anatomical locations.Injection sites are in upper and lower extremities. Subsequent DC injections will be rotated to different locations on the upper and lower extremities.
