  Purpose
This study will assess the safety and effectiveness of intratumoral plasmid interleukin-12 DNA injection (pIL-12) with electroporation (EP) in malignant melanoma. Intratumoral pIL-12 EP is a gene therapy approach to directly induce a pro-inflammatory response within a tumor to initiate and/or enhance anti-tumor immunity.

Condition Intervention Phase
Melanoma Biological: Plasmid INTERLEUKIN-12 Device: Intratumoral Electroporation Phase 2

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Multicenter Phase II Trial of Intratumoral pIL-12 Electroporation in Advanced Stage Cutaneous and in Transit Malignant Melanoma

Arms Assigned Interventions
Experimental: Main Study
Plasmid interleukin-12 followed by intratumoral electroporation (pIL-12 EP). Treatment cycles consisting of 3 treatments over 1 week period, repeated at 3-month intervals until disease progression or unacceptable toxicity for up to 1 year.
Biological: Plasmid INTERLEUKIN-12
Patients will receive intratumoral injection(s) of pIL-12.
Other Name: pIL-12
Device: Intratumoral Electroporation
Immediately following intratumoral injection of pIL-12, electroporation will follow by electrical discharge around the tumor site using the OMS system.
Other Name: EP
Experimental: Addendum Study
Plasmid interleukin-12 followed by intratumoral electroporation (pIL-12 EP). Treatment cycles occur every 6 weeks and two treatment regimens will be explored: Regimen A [treatment on days 1, 8 and 15] -or- Regimen B [treatment on days 1, 5, and 8] and repeated up to 9 treatment cycles (1 year) until disease progression or unacceptable toxicity.
Biological: Plasmid INTERLEUKIN-12
Patients will receive intratumoral injection(s) of pIL-12.
Other Name: pIL-12
Device: Intratumoral Electroporation
Immediately following intratumoral injection of pIL-12, electroporation will follow by electrical discharge around the tumor site using the OMS system.
Other Name: EP

Detailed Description:

Plasmid IL-12 (pIL-12) at a concentration of 0.5 mg/mL will be injected intratumorally at a dose volume of ¼ of the calculated lesion volume and a dose volume per lesion of 0.1 mL for lesions of volume < 0.4 cm3. Six pulses at field strengths of (E+) of 1500 V/cm and pulse width of 100 μs at 1-second intervals will be administered using the OMS to each previously injected tumor.

Two treatment regimens will be explored:

Regimen A: Treatment on Days 1, 8 and 15 every 6 weeks Regimen B: Treatment on Days 1, 5 and 8 every 6 weeks. Lesions will be treated on either Regimen A or Regimen B. Subsequent cycles may be given at 6-week intervals, for up to 9 treatment cycles in total.
