Brief Summary:

This research study is studying the drugs called NeoVax (a new type of personalized neoantigen vaccine) in combination with CDX-301 and Nivolumab as a possible treatment for melanoma.

The names of the study drugs involved in this study are:

  • Personalized Neoantigen peptides (which combined with poly-ICLC make the vaccine NeoVax)
  • Poly-ICLC (Hiltonol)
  • CDX-301
  • Nivolumab (Opdivo)

Condition or disease Intervention/treatment Phase
Melanoma Metastatic Melanoma Drug: CDX-301 Biological: NEOVAX Drug: Nivolumab Phase 1

Detailed Description:

The purpose of this Phase I study is to determine if it is possible to safely administer a personalized neoantigen vaccine (NeoVax) in combination with the study drug CDX-301 and Nivolumab against melanoma by using information gained from specific characteristics of someone's own melanoma. The study will also be determining what the appropriate dose of CDX-301 to be given in combination with NeoVax and Nivolumab.

The FDA (the U.S. Food and Drug Administration) has not approved personalized neoantigen peptides, poly-ICLC , or CDX-301 as a treatment for any disease.

The FDA has approved Nivolumab as a treatment option for metastatic melanoma.

It is known that melanoma cancers have mutations (changes in genetic material) that are specific to an individual patient and tumor. These mutations can cause the tumor cells to produce proteins that appear very different from the body's own cells.It is possible that these proteins used in a vaccine may induce strong immune responses, which may help someone's body fight any tumor cells that could cause the melanoma to come back in the future.

The personalized Neovax vaccine will be made of protein fragments, called peptides, from an individual's mutated melanoma tumor cells mixed with Poly-ICLC. Poly-ICLC is a drug that binds proteins on the surface of certain immune cells and helps to activate the immune system.

CDX-301 is a drug involved in regulating the activity and proliferation of a type of cell named dendritic cell. Dendritic cells are key in enhancing the activation of the immune system in response to the NeoVax vaccine, so the immune system has a better chance to recognize the tumor cells and attack them.

Nivolumab is an antibody that prevents cancer cells from suppressing one's immune response so that their body can attack and kill the cancer.

The research study procedures include: screening for eligibility and study treatment including evaluations and follow up visits.

Participants will receive study treatment for as long as they do not have serious side effects and their disease does not get worse for a maximum of 2 years and will be followed for 5 years since study therapy initiation

It is expected that about 20 people will take part in this research study

Celldex Therapeutics is supporting this research by providing CDX-301.

Criteria

Inclusion Criteria:

Eligibility to participate will be assessed at two timepoints: prior to initial core needle/surgical biopsy (Initial Registration) and prior to the first vaccination (Secondary Registration).

  • Eligibility Criteria for Initial Registration

    • Participant is willing and able to give written informed consent
    • Participants must have histologically confirmed cutaneous melanoma (mucosal melanoma or uveal melanoma are excluded) that is unresectable stage III or stage IV; at least one site of disease must be resectable, partially-resectable, or amenable to core biopsies to provide tumor tissue for sequence analysis
    • Participants must have measurable disease by RECIST v1.1 that has not been treated with local therapy within the last 12 months of study treatment. The measurable lesion and the lesion used for surgical or core biopsies can be identical as long as it remains measurable after biopsy
    • Age ≥ 18 years
    • ECOG performance status of 0 or 1
    • Recovered from all toxicities associated with prior treatment, to acceptable baseline status (as to Lab toxicity see below limits for inclusion) or a National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 5.0, Grade of 0 or 1, except for toxicities not considered a safety risk, such as alopecia or vitiligo
    • Participants must have normal organ and marrow function as defined below:

      • WBC ≥3,000/µL
      • ANC ≥1,500/µL
      • Platelets ≥100,000/µL
      • Hemoglobin ˃ 9.0 g/dL
      • Total Bilirubin ≤ 1.5 x ULN (except subjects with Gilbert Syndrome, who can have total bilirubin < 3.0 mg/dL)
      • AST(SGOT)/ALT(SGPT) ≤ 3 x ULN
      • Creatinine ≤ 1.5 x ULN OR
      • Creatinine clearance ≥40 mL/min/1.73 m2 for participants with creatinine levels above institutional normal (if using the Cockcroft-Gault formula below):

Female CrCl = (140 - age in years) x weight in kg x 0.85 72 x serum creatinine in mg/dL

Male CrCl = (140 - age in years) x weight in kg x 1.00 72 x serum creatinine in mg/dL

  • Women of childbearing potential (WOCBP) should have a negative serum pregnancy test (minimum sensitivity 25 IU/L or equivalent units of HCG) within 24 hours prior to the start of Nivolumab, because the effects of NeoVax plus Montanide and Nivolumab on the developing human fetus are unknown
  • Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with study agents, breastfeeding should be discontinued if the mother is treated Nivolumab, Personalized Neoantigen vaccine, and CDX-301
  • Female participants enrolled in the study, who are not free from menses for >2 years, post hysterectomy / oophorectomy, or surgically sterilized, should be willing to use either 2 adequate barrier methods or a barrier method plus a hormonal method of contraception to prevent pregnancy or to abstain from sexual activity throughout the study, starting with visit 1 through 5 months after the last dose of study therapy. Approved contraceptive methods include for example: intra uterine device, diaphragm with spermicide, cervical cap with spermicide, male condoms, or female condom with spermicide. Spermicides alone are not an acceptable method of contraception. 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.The investigational product will be permanently discontinued in an appropriate manner.
  • Male participants should agree to use an adequate method of contraception starting with visit 1 through 7 months after the last dose of study therapy

Exclusion Criteria:

  • Prior immunotherapy for metastatic melanoma except anti-CTLA-4. Patients who have received PD-1 inhibition therapy as adjuvant therapy and stopped receiving PD-1 inhibition for a period of ≥ 6 months before starting treatment with Nivolumab are allowed to participate.
