Short Title/Acronym: ABSIDE (ABScopal effect-Interferon alpha-DEndritic cells)

Phase: phase II clinical trial

Study Design: Randomized selection design, proof of principle study

Study Duration: 36 months

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.
