Modified Melanoma Vaccine for High Risk or Low Residual Disease Patients

• Status: Unknown status
• Trial end date: 2019-04-01
• Target enrollment: 0
• Participant gender: All

Summary

This study is designed for patients who had malignant melanoma and, following tumor removal, are now free of disease, or have only very minor residual disease, and are at a very high risk of disease recurrence. These patients will be treated with the A2/4-1BBL melanoma vaccine, a compatible melanoma cell line that has been engineered to express a molecule termed 4-1BBL, which enhances the chances of the cell line to be recognized by the patient's immune system, and to induce its stimulation. The hypothesis that drives the study states that the immune response against the cell line will also be effective against the residual tumor that may still be present in the body.

3. Metastatic melanoma AJCC stage III (nodal involvement, N1-3a,b) post-surgical removal of lymph nodes.

4. Metastatic melanoma AJCC stage IV, completely resected.

5. Non-resectable metastatic melanoma of low burden disease and normal LDH who have undergone at least two treatment lines, including chemotherapy (DTIC, temodal, taxanes, platinum compounds), anti-CTLA-4 (ipilimumab) and B-RAF inhibitor if harboring the V600E BRAF mutation in their tumor.

6. Non cutaneous malignant melanoma of respective stages including uveal and mucosal melanoma.

7. Melanoma can be of either mutant or wild-type B-RAF.

9. No active cardio-respiratory disease.

10. Not pregnant or nursing. Women must take contraceptives during the treatment period.Hematocrit >25% and WBC >3000.

11. Informed consent of the patient.

Exclusion Criteria:

1. Administration of cytotoxic drugs or extensive radiotherapy less than 28 days prior to protocol administration.

2. Active brain metastases requiring corticosteroids.
