This research study is investigating a new type of personalized neoantigen vaccine, NeoVax, plus Montanide® in combination with Ipilimumab (Yervoy™) and Nivolumab (Opdivo®) as a possible treatment for cutaneous melanoma.
The drugs involved in this study are:
Full description
This is a Phase I clinical trial to assess the safety of an investigational personalized neoantigen vaccine, NeoVax, consisting of personalized neoantigen peptides and Hiltonol® plus Montanide®, in combination with Nivolumab and Ipilimumab. The study also seeks to define the appropriate dose of investigational Ipilimumab administered subcutaneously (under the skin) to use for further studies. "Investigational" means that the combination is being studied. The FDA (the U.S. Food and Drug Administration) has not approved personalized neoantigen peptides, Hiltonol®, or Montanide® as a treatment for any disease. The combination is an investigational therapy being developed for use in the treatment of certain cancers. The FDA has approved Nivolumab (Opdivo®) and intravenous Ipilimumab (Yervoy™) as a treatment option for melanoma. Subcutaneous administration of Ipilimumab has not been approved by the FDA for treatment of melanoma.
It is known that melanoma cancers have mutations (changes in genetic material) that are specific to each 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 the proteins used in a vaccine may cause strong immune responses, which may help the body fight any tumor cells that could allow the melanoma to come back in the future.
In this study, melanoma cells will be obtained either by tumor surgery or tumor biopsy. The genetic material contained in the melanoma cells will be examined for the presence of tumor-specific mutations. This information will be used to prepare small protein fragments, which are called "peptides". Each NeoVax vaccine will consist of up to 20 peptides mixed with two drugs that activate the immune system called Poly-ICLC (Hiltonol®) and Montanide®.
A 5-patient dose escalation design will be implemented with up to three cohorts of patients. Each cohort of patients (5 patients/cohort) will begin treatment with Nivolumab (480 mg intravenously every 4 weeks). The NeoVax vaccine will be prepared during the initial 12 weeks of Nivolumab therapy. Any patient for whom vaccine cannot be made will be replaced within a cohort. Vaccine will be administered on weeks 12, 15, 18, and 21 with Hiltonol, Montanide, and concurrent Ipilimumab. The protocol specifies that the dose of Ipilimumab will begin at 2.5 mg per injection site. If the number of dose-limiting toxicities (DLTs) occurring within 7 weeks of NeoVax initiation is 0 or 1 (i.e., in no more than 20% of patients) the dose of Ipilimumab will be increased to 5 mg per injection site in the next cohort. If the number of DLTs is 2 or more, the dose of Ipilimumab will be decreased to 1.25 mg per injection site in the next cohort. The maximum tolerated dose (MTD) will be the highest dose of Ipilimumab in which the DLT rate is 20% or less.
Toxicities will be graded using the Common Terminology Criteria for Adverse Events Version 5.0 (CTCAE 5.0).
A DLT is defined as:
Health status assessments, including physical exams and blood chemistry, will be conducted every 4 weeks. Leukapheresis will occur at the time of enrollment, prior to administration of the first dose of NeoVax, and at week 20. For patients with unresectable melanoma, tumor biopsies will be obtained prior to the first dose of vaccine, at week 20, and at the time of disease progression. Vaccine site biopsies will be obtained at weeks 15 and 18 (i.e., at the times of the second and third vaccine administration).

Volunteers
Inclusion criteria
Participant is willing and able to give written informed consent
Participants must have histologically confirmed cutaneous melanoma 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 with mucosal or uveal melanoma are excluded.
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 4, 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:
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 with Ipilimumab, Nivolumab and Personalized Neoantigen vaccine + Montanide.
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 23 weeks (30 days plus the time required for Nivolumab to undergo five half-lives) 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.
Male participants should agree to use an adequate method of contraception starting with visit 1 through 31 weeks after the last dose of study therapy
Eligibility Criteria for Secondary Registration
ECOG performance status of 0 or 1
Screening laboratory values must meet the following criteria and should be obtained within 7 days prior to registration
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 with Ipilimumab, Nivolumab and Personalized Neoantigen vaccine + Montanide.
