Phase I Study of gp75 DNA Vaccine in Patients With AJCC Stage III and IV Melanoma
In Brief
A Phase 1 clinical trial evaluating gp75 DNA vaccine for Malignant Melanoma. Completed, enrolled 31 participants across 1 site.
Detailed Summary
Up to 24 patients with stage III or stage IV melanoma will be enrolled. Patients who are currently disease-free but at high risk for relapse are also eligible. Patients will receive vaccinations of gp75 at assigned dose levels. Patients who exhibit serologic and stable/clinical response are eligible to receive booster vaccinations. Patients will be evaluated for safety and efficacy throughout the duration of the study. In this study, the optimal biologically effective dose is defined as the lowest dose of gp75 that results in the production of anti-gp75 antibodies.

Timeline
Interventions
6 patients will be enrolled in each of the 5 vaccination groups. Patients in vaccination groups 1-3 will receive a total of 5(1 mL) vaccinations. Patients assigned to vaccination group 4 will receive a total of 5 (2.0 mL) vaccinations administered as 2 1 mL injections. Patients assigned to vaccination group 5 will receive a total of 5 (4.0 mL or 8.0 mg)vaccinations administered as 4 1 mL injections per vaccination treatment Patients will receive gp75 DNA vaccinations every 3 weeks for 5 vaccinations. Injection sites will be given intramuscularly and rotated for each dose using all 4 limbs with the exception of a site that had the removal of lymph nodes. Progression to next higher dose level will be based on the 5\* patient safely completing the 2nd vaccination at the lower dose level.
