Summary

Title: Vaccination with autologous dendritic cells loaded with autologous tumor lysate or homogenate combined with immunomodulating radiotherapy and/or preleukapheresis IFN-alfa in patients with metastatic melanoma: a randomized "proof-of-principle" phase II study.

Study Design: Randomized selection design, proof of principle study Study Duration: 36 months Number of Subjects: 24 evaluable patients

Diagnosis and Main Inclusion Criteria: Patients with non resectable stage III or stage IV malignant melanoma carrying at least 2 measurable lesions, any line after 1st line Vemurafenib in patients carrying BRAF mutation-positive melanoma and/or ≥ 2nd line Ipilimumab.

Study Product, Dose, Route, Regimen and duration of administration:

Intradermal Autologous Dendritic Cell vaccine loaded with autologous tumor lysate or homogenate on weeks 1, 4 6 and 8 during induction phase, and every 4 weeks during maintenance phase up to a maximum of 14 vaccine doses (each dose followed by IL-2 3 MU day 2-6) COMBINED OR NOT WITH

* IFN-alfa 3 MU daily for 7 days before leukapheresis AND/OR
* Three daily doses of 8 Gy up to 12 Gy delivered to one metastatic field between vaccine doses 1 and 2 (optional to one additional field between doses 7 and 8) utilizing IMRT-IMAT techniques.

Conditions

  • Malignant Melanoma of Skin Stage III
  • Malignant Melanoma of Skin Stage IV

Interventions

OTHER

arm 1: DC Vaccine + RT

three daily doses of 8 Gy up to 12 Gy delivered to one non-index metastatic field between vaccine doses 1 and 2 (optional to one additional field between vaccine doses 7 and 8) utilizing IMRT-IMAT techniques

OTHER

arm 2: DC Vaccine + IFN-alfa

daily 3 MU subcutaneous IFN-alfa for 7 days before leukapheresis (day -15 to -9, and for 7 days before any other additional leukapheresis)

OTHER

arm 3: both arm 1 and 2 + RT

both 1 and 2 external immunostimulant conditions (Intradermal Autologous Dendritic Cell Vaccine + 3 single boosts of RT + IFN-alfa, 3 MU daily for 7 days before leukapheresis)

BIOLOGICAL

arm 4: DC Vaccine

neither 1 or 2 external immunostimulant conditions (only Intradermal Autologous Dendritic Cell Vaccine)
