A Phase II, Open-Label, Multicenter, Randomized Study of CDX-1401, a Dendritic Cell Targeting NY-ESO-1 Vaccine, in Patients With Malignant Melanoma Pre-treated With Recombinant CDX-301, a Recombinant Human Flt3 Ligand

This randomized phase II trial studies how well DEC-205/NY-ESO-1 fusion protein CDX-1401 (CDX-1401) and neoantigen-based melanoma-poly-ICLC vaccine (poly-ICLC) vaccine therapy work when given with or without recombinant flt3 ligand (CDX-301) in treating patients with stage IIB-IV melanoma. The cancer vaccine CDX-1401 attaches to a protein that is made in tumor cells. The vaccine helps the body recognize the tumor to fight the cancer. The CDX-301 vaccine may help the body make more of the tumor fighting cells, known as dendritic cells. The poly-ICLC vaccine stimulates the immune system and may help these dendritic cells mature so that they can recognize the tumor. It is not yet known whether CDX-1401 and poly-ICLC will work better with or without CDX-301 in treating melanoma.


     I. To determine whether the immune response to cancer/testis antigen 1B (NY-ESO-1) elicited by vaccination with CDX-1401 (anti-DEC205-NY-ESO-1 fusion protein vaccine) plus polyinosinic-polycytidylic acid stabilized with poly-L-lysine and carboxymethylcellulose (poly-ICLC) is substantially increased by prior expansion in the number of circulating dendritic cells (DC) by therapy with CDX-301 (fms-related tyrosine kinase 3 ligand [Flt3L]) (recombinant flt3 ligand).

     II. To determine whether the proportion of responders to NY-ESO-1 is > 50% when T cell responses are elicited by vaccination with CDX-1401 plus poly-ICLC in combination with CDX-301 (Flt3L) 75 mcg/kg/day administered prior to vaccination for 5 days in both of the first two vaccine cycles; and for 5 days in the first vaccine cycle only.


     I. To assess the effect of the vaccine regimen on immune responses to other ongoing and nascent antitumor response antigens associated with melanoma (e.g., PRAME, MAGE-A3, p53, and gp100) as well as memory viral responses (influenza A) and chronic viral responses (cytomegalovirus [CMV], Epstein-Barr virus [EBV]).

     II. To assess the effect of the vaccine regimen on the frequency and phenotypic character of peripheral blood mononuclear cell (PBMC) subsets including DCs, monocyte populations, T cells, and natural killer (NK) cells.

     III. To assess the safety, tolerability, and clinical efficacy of the vaccine regimens.

     OUTLINE: Patients are randomized to 1 of 4 treatment arms.

     ARM I: Patients receive recombinant flt3 ligand subcutaneously (SC) on days -7 to -1, 1-3, and 22-28 of course 1 and on days 1-3 of course 2 only; DEC-205/NY-ESO-1 fusion protein CDX-1401 SC or intradermally (ID) on day 1; and poly-ICLC SC on days 1 and 2. Treatment repeats every 28 days for 4 courses in the absence of disease progression or unacceptable toxicity.

     ARM II: Patients receive DEC-205/NY-ESO-1 fusion protein CDX-1401 and poly-ICLC as in Arm I. Treatment repeats every 28 days for 4 courses in the absence of disease progression or unacceptable toxicity.

     ARM III: Patients receive recombinant flt3 ligand SC on days -7 to -3 and 22-26 of course 1 only and DEC-205/NY-ESO-1 fusion protein CDX-1401 and poly-ICLC as in Arm I. Treatment repeats every 28 days for 4 courses in the absence of disease progression or unacceptable toxicity.

     ARM IV: Patients receive recombinant flt3 ligand SC on days -7 to -3 of course 1 only, and DEC-205/NY-ESO-1 fusion protein CDX-1401 and poly-ICLC as in Arm I. Treatment repeats every 28 days for 4 courses in the absence of disease progression or unacceptable toxicity.

     After completion of study treatment, patients are followed up at 4 and 12 weeks and then annually thereafter.
