Vaccine Therapy in Treating Patients With Stage IV Melanoma

Phase 1
Completed
Conditions
Melanoma (Skin)
Interventions
Biological: MKC1106-MT
Registration Number
NCT00033228
Lead Sponsor
Mannkind Corporation
Brief Summary

RATIONALE: Vaccines may make the body build an immune response to kill tumor cells. Infusing the vaccine directly into a lymph node may cause a stronger immune response and kill more tumor cells.

PURPOSE: Phase I/II trial to study the effectiveness of vaccine therapy in treating patients who have stage IV melanoma.

Detailed Description

OBJECTIVES:

* Determine the maximum tolerated dose of intranodal Synchrovax SEM plasmid DNA vaccine in patients with stage IV melanoma.

* Determine the safety and tolerability of this drug in these patients.

* Determine the immunological response, as measured by changes in frequency of T cells specific against vaccine-encoded epitopes before and after treatment, in patients treated with this drug.

* Determine the clinical response, as measured by lactic dehydrogenase levels and radiologic assessment of lesions, in patients treated with this drug.

OUTLINE: This is a multicenter, dose-escalation study.

Patients receive Synchrovax SEM plasmid DNA vaccine by continuous intranodal infusion on days 1-4. Treatment repeats every 14 days for up to 4 courses in the absence of unacceptable toxicity. Patients with evidence of stable or responding disease are eligible for 4 additional courses of treatment.

Cohorts of 6 patients receive escalating doses of Synchrovax SEM plasmid DNA vaccine until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which at least 2 of 6 patients experience dose-limiting toxicity.

Patients are followed at 10 days after the last dose of study drug.

PROJECTED ACCRUAL: A total of 6-18 patients will be accrued for this study.

Cohort 1MKC1106-MTThe first cohort of 6 patients received 500 ug of Synchrovax SEM plasmid DNA vaccine. All patients were to be monitored for dose limiting toxicities DLTs) for a minimum of 2 weeks after their second infusion of vaccine on Day 15 before allowing patients to enroll at the next dose group. The decision to progress to the next dose group was to be based on occurrence of DLTs observed in 1 or fewer (\<33%) patients of a 6 patient cohort.
Cohort 2MKC1106-MTThe second cohort of 6 patients received 1000 ug of Synchrovax SEM plasmid DNA vaccine. All patients were to be monitored for dose limiting toxicities DLTs) for a minimum of 2 weeks after their second infusion of vaccine on Day 15 before allowing patients to enroll at the next dose group. The decision to progress to the next dose group was to be based on occurrence of DLTs observed in 1 or fewer (\<33%) patients of a 6 patient cohort.
Cohort 3MKC1106-MTThe third cohort of 6 patients received 1500 ug of Synchrovax SEM plasmid DNA vaccine. The maximum tolerated dose (MTD) was to be determined by the observation of DLT at each dose group.
Primary Outcome Measures
NameTimeMethod
The primary objective of the study was to evaluate the safety and tolerability of Synchrovax® pSEM Vaccine measured by the adverse event and severe adverse event profile.
Secondary Outcome Measures
NameTimeMethod
The secondary objective of the study was to determine the immunological response of patients as measured by tetramer assay and to assess clinical response by LDH levels and radiological assessment of lesions.
