A Clinical Trial to Evaluate a Melanoma Helper Peptide Vaccine Plus Dabrafenib and Trametinib

Study Purpose

This study evaluates whether it is safe to administer a helper peptide vaccine with dabrafenib and trametinib. This study will also evaluate the effects of the combination of the peptide vaccine and dabrafenib and trametinib on the immune system. We will monitor these effects by performing tests in the laboratory on participants' blood and tumor samples.

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

More Inclusion & Exclusion Criteria

Inclusion Criteria:

These participants may have had cutaneous, uveal, mucosal primary melanoma, or an unknown primary melanoma. Staging must be confirmed by cytological or histological examination. Staging of cutaneous melanoma will be based on the revised AJCC 8th Edition staging system (Appendix 2) 66.

Patients known to have Gilbert's disease may be eligible with AST and ALT up to 5 x ULN.
  • - Bilirubin up to 2.5 x ULN - Alkaline phosphatase up to 2.5 x ULN.
  • - Creatinine up to 1.5 x ULN - Age 18 years or older at registration - Participants must have at least two intact (undissected) axillary and/or inguinal lymph node basins

    Exclusion Criteria:

    - Participants who have received the following medications or treatments at any time within 4 weeks of registration: - • Chemotherapy - Interferon (e.g. Intron-A®) - Radiation therapy (Stereotactic radiotherapy, such as gamma knife, can be used ≥ 1 week and ≤ 6 months prior to registration) - Allergy desensitization injections - Corticosteroids, administered transdermally, parenterally or orally.
Inhaled steroids (e.g.: Advair®, Flovent®, Azmacort®) are not permitted. Topical corticosteroids are acceptable.
  • - Growth factors (e.g. Procrit®, Aranesp®, Neulasta®) - Interleukins (e.g. Proleukin®) - Any investigational medication - HIV positivity or evidence of active Hepatitis C virus.
  • - Participants who are currently receiving nitrosoureas or who have received this therapy 6 weeks prior to registration - Participants who are currently receiving a checkpoint molecule blockade therapy, or who have received this therapy within 3weeks prior to registration.
  • - Participants with known or suspected allergies to any component of the vaccine.
  • - Participants may not have been vaccinated previously with any of the synthetic peptides included in this protocol.
Participants who have received vaccinations containing agents other than the synthetic peptides included in this protocol and have recurred during or after administration of the vaccine will be eligible to enroll 12 weeks following their last vaccination.
  • - Pregnancy.
  • - Female participants must not be breastfeeding - Participants in whom there is a medical contraindication or potential problem in complying with the requirements of the protocol in the opinion of the investigator.
  • - Participants classified according to the New York Heart Association classification as having Class III or IV heart disease.
  • - Participants with uncontrolled diabetes, defined as having a HgB-A1c greater than 7.5%.
  • - Participants must not have had prior autoimmune disorders requiring cytotoxic or immunosuppressive therapy, or autoimmune disorders with visceral involvement.
Participants with an active autoimmune disorder requiring these therapies are also excluded.
  • - Participants who have another cancer diagnosis, except that the following diagnoses will be allowed: - squamous cell cancer of the skin without known metastasis - basal cell cancer of the skin without known metastasis - carcinoma in situ of the breast (DCIS or LCIS) - carcinoma in situ of the cervix - any cancer without distant metastasis that has been treated successfully, without evidence of recurrence or metastasis for over 3 years - Participants with known addiction to alcohol or drugs who are actively taking those agents, or participants with recent (within 1 year of registration) or ongoing illicit IV drug use.
  • - Body weight < 110 pounds - Participants with a known history of glucose-6-phosphate dehydrogenase deficiency.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT02382549
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Arms & Interventions

Arms

Experimental: 6MHP and dabrafenib and trametinib

The vaccine drug product, 6MHP, consists of 6 class II MHC-restricted peptides derived from melanoma proteins. Each vaccine consists of 200 mcg of each of the six peptides. An aqueous solution of vaccine is mixed 1/1 with Montanide ISA-51 to form water-in-oil emulsions. Vaccines are administered days 1, 8, 15, 36, 57, 78. All peptide vaccines are administered intradermally and subcutaneously. Dabrafenib is a small molecular BRAF inhibitor and will be administered in accordance with the prescribing information: 150 mg orally twice daily taken at least 1 hour before or at least 2 hours after a meal; the doses will be approximately 12 hours apart. Trametinib is a small molecular MEK1 and MEK2 inhibitor and will be administered in accordance with the prescribing information: 2 mg orally once daily taken at least 1 hour before or at least 2 hours after a meal. The medication will be taken at the same time each day with either the morning or evening dose of dabrafenib.
