    Exclusion Criteria:

    1.

Patients with unresectable or metastatic melanoma BRAF V600 mutation-positive eligible to Vemurafenib cannot be enrolled in first line, unless they refuse this treatment. 3. Patients eligible for Ipilimumab treatment, cannot be enrolled unless they refuse this treatment. 4. Patients who have had chemotherapy or radiotherapy within 4 weeks prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier. 5. Participation in another clinical trial with any investigational agents within 30 days prior to study screening. 6. Patients with known progressing and/or symptomatic brain metastases. 7. Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements (on physician's judgment). 8. Other known malignant neoplastic diseases in the patient's medical history with a disease-free interval of less than 3 years (except for previously treated basal cell carcinoma and in situ carcinoma of the uterine cervix); 9. Any contraindication to undergo leukapheresis as evaluated by transfusionist (e.g. severe anemia, piastrinopenia, oral anticoagulant therapy).

NCT01973322
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

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. Short Title/Acronym: ABSIDE (ABScopal effect-Interferon alpha-DEndritic cells) Protocol Code IRST172.02 Phase: phase II clinical trial Study Design: Randomized selection design, proof of principle study Study Duration: 36 months Study Center(s): Monocentric (IRCCS IRST Meldola) Objectives: Primary objectives 1. Safety assessments: to determine the safety of the autologous tumor lysate loaded DC vaccine in combination with IFN-alfa and/or radiotherapy in patients with advanced melanoma. 2. Clinical objective: to select the regimen that has the best immune related Disease Control Rate (irDCR) in the different external immunostimulant conditions utilized in combinations with autologous tumor lysate loaded DC vaccine. 3. Immunological objective: to compare between the different treatment arms the immunologic efficacy, defined as the proportion of subjects developing positive DTH to ATL and/or KLH, combined with quantification of tumor antigen-specific circulating immune effectors performed by IFNalfa-ELISPOT analysis at the base line and after at least 4 immunizations, if DTH analysis will not detect differences in terms of immunologic efficacy between the different arms. 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.
Statistical Methodology: The RANDOMIZED SELECTION DESIGN was chosen basing on the assumption that immunotherapy is expected to be effective only in patients showing efficient induction of antitumor immune responses ("targeted endpoint"), allowing to reduce the number of patients required to evaluate the potential efficacy of an experimental treatment. The Steinberg and Venzon approach will be employed to select one among different treatment arms as being worthy of further evaluation. This method requires that an adequate gap in the number of responses among different arms be observed in order to limit the probability that the selected arm is actually inferior by more than an indifferent amount. Assuming an error probability of selecting inferior arm pW =10%, with 6 patients per arm, regardless of proportion of irOR expected in each arm, the gap of 2, the largest minimal difference in the number of irOR which must be observed in order to select the arm with the higher number of irOR, provides that difference between highest probability of response and the maximum on the remaining arms is 15%. Therefore, outcomes of at least 4/6 versus the maximum on the remaining 3 arms of 2/6, at least 5/6 versus the maximum on the remaining 3 arms of 3/6 and so forth will lead to selection the most promising arm on the basis of irOR. with an error probability of 10% Otherwise no treatment arm could be considered better than others.
