Drug: Poly ICLC
Biological: Recombinant Flt3 Ligand

Registration Number: NCT02129075

Lead Sponsor: National Cancer Institute (NCI)

Brief Summary: This phase II trial studies the effect of a vaccine called CDX-1401 given with or without a biologic drug called 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 biologic drug CDX-301 may help the body make more of the tumor fighting cells, known as dendritic cells. Another biologic drug, poly-ICLC, may stimulate the immune system and help these dendritic cells mature so that they can recognize the tumor. Giving CDX-301 may make the immune response to a combination of CDX-1401 and poly-ICLC better.

Detailed Description: PRIMARY OBJECTIVE:

I. To determine whether the immune response to NY-ESO-1 elicited by vaccination with DEC-205/NY-ESO-1 fusion protein CDX-1401 (CDX-1401) 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 recombinant Flt3 ligand (CDX-301) (fms-related tyrosine kinase 3 ligand \[Flt3L\]).

SECONDARY OBJECTIVES:

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 2 treatment arms.

ARM I: Patients receive recombinant Flt3 ligand (CDX-301) subcutaneously (SC) on days -7 to -1, 1-3, and 22-28 of cycle 1 and only on days 1-3 of cycle 2. Patients also receive CDX-1401 SC or intradermally (ID) on day 1 of each cycle and poly-ICLC SC on days 1-2 of each cycle. Treatment repeats every 28 days for 4 cycles in the absence of disease progression or unacceptable toxicity.

ARM II: Patients receive CDX-1401 and poly-ICLC as in Arm I. Treatment repeats every 28 days for 4 cycles 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.

Prior radiation, chemotherapy or biologics NOT allowed
Not currently receiving any anticancer therapy
Age >= 18 years
- Because no dosing or adverse event (AE) data are currently available on the use of CDX-1401 or CDX-301 in patients < 18 years of age, children are excluded from this study, but will be eligible for future pediatric trials.
Eastern Cooperative Oncology Group (ECOG) performance score of 0-1
Life expectancy of at least 6 months
Leukocytes >= 3,000/mcL
Absolute neutrophil count >= 1,000/mcL
Platelets >= 75,000/mcL

Total bilirubin < 1.5 x institutional upper limit of normal (bilirubin < 3 x institutional upper limit of normal for Gilbert's syndrome)
Aspartate aminotransferase (AST)(serum glutamic-oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT)(serum glutamate pyruvate transaminase [SGPT]) =< 2.5 x institutional upper limit of normal
Creatinine < 1.5 x institutional upper limit of normal OR creatinine clearance >= 60 mL/min/1.73 m^2 for patients with creatinine levels above institutional normal
The first six patients enrolled in the Flt3L arm of the study cannot be human immunodeficiency virus (HIV)-positive. After the evaluation of safety in the first 6 patients, HIV-positive patients with adequate immune function as evidenced by stable CD4 counts >= 350/mm^3 are allowed to participate if the following criteria are met:
- maintained on stable antiretroviral therapy with no significant drug interactions, and
- no recent history of acquired immunodeficiency syndrome (AIDS) indicator conditions (> 2 years from enrolling in trial), and
- physician providing patient's care for HIV must also approve of patient entering the study
Females of childbearing potential must have a negative pregnancy test within 7 days before the initiation of protocol therapy.
- The effects of CDX-1401 or CDX-301 on the developing human fetus are unknown. For this reason, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control or abstinence) before study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. Men treated or enrolled on this protocol must also agree to use adequate contraception before the study, for the duration of study participation, and 4 months after completion of CDX-1401 or CDX-301 administration.
- NOTE: Subjects are considered not of child-bearing potential if they are surgically sterile, they have undergone a hysterectomy, bilateral tubal ligation, or bilateral oophorectomy, or they are postmenopausal. Menopause is the age associated with complete cessation of menstrual cycles, menses, and implies the loss of reproductive potential. By a practical definition, it assumes menopause after 1 year without menses with an appropriate clinical profile at the appropriate age.
Ability to understand and the willingness to sign a written informed consent document

Exclusion Criteria

Patients who have had cytotoxic chemotherapy, radiotherapy, interferon (IFN), or ipilimumab before entering the study
Immunosuppressive therapy within 30 days prior to initiation of protocol therapy
Steroid therapy, or steroid therapy with more than 7 consecutive days of steroids within the prior 4 weeks
- The use of prednisone or equivalent < 0.125 mg/kg/day (absolute maximum of 10 mg/day) as replacement therapy is permitted
- Inhaled or topical corticosteroids are permitted
Patients who are receiving any other investigational agents
Current or history of systemic autoimmune disease requiring systemic therapy.
- NOTE: The following will not be exclusionary:

- NOTE: Patients with brain metastasis, after definitive therapy with surgery or stereotactic radiation and stable off steroids for >= 4 weeks, are eligible
Other invasive cancers that are clinically active
Pregnancy or nursing or unwilling to take adequate birth control during therapy
- NOTE: Pregnant women are excluded from this study because CDX-1401 or CDX-301 and poly-ICLC have an unknown potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with CDX-1401 or CDX-301, breastfeeding should be discontinued if the mother is treated with CDX-1401 or CDX-301 and poly-ICLC
History of allergic reactions attributed to compounds of similar chemical or biologic composition to CDX-1401 or CDX-301 or poly-ICLC
Prior organ allograft or allogeneic transplantation, if the transplanted tissue is still in place
