Safety Study of a Helper Peptide Vaccine Plus Adjuvant Combinations for the Treatment of Melanoma

Stopped early · Phase 1/Phase 2

Conditions studied: Melanoma

In brief

This study evaluates whether it is safe to administer a peptide vaccine in combination with different adjuvants. Adjuvants are substances that may boost immune responses vaccines. In this study, the adjuvants are Montanide ISA-51, polyICLC and cyclophosphamide. This study will also evaluate the effects of the combination of the peptide vaccine and the adjuvants on the immune system. The investigators will monitor these effects by performing tests in the laboratory on participants' blood, a lymph node, and tissue from the sites of vaccination.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Part 1 only: Participants with stage IIB, IIC, III, or IV melanoma at original diagnosis or at restaging after recurrence. Patients with high-risk stage IIA melanoma (by DecisionDx Melanoma test, Castle Biosciences, Inc,;Friendswood, TX) also may be eligible. These participants may have had cutaneous, uveal, mucosal primary melanoma, or an unknown primary melanoma. Diagnosis of melanoma must be confirmed by cytological or histological examination. Staging of cutaneous melanoma will be based on version 7 AJCC staging system.
• Part 2 only: Patients with a diagnosis of stage IIIB-IV melanoma with one or more tumor deposits accessible for biopsy and/or excision. These participants may have had cutaneous, uveal, mucosal primary melanoma, or an unknown primary melanoma. Diagnosis of melanoma must be confirmed by cytological or histological examination. Staging of cutaneous melanoma will be based on version 7 AJCC staging system.
• Patients must have adequate cutaneous, subcutaneous, soft tissue, or nodal metastases of melanoma readily accessible for biopsy
• Participants will be required to have radiological studies to rule out radiologically evident disease. Required studies include:
• Chest CT scan,
• Abdominal and pelvic CT scan, and
• Head CT scan or MRI
• PET/CT fusion scan may replace scans of the chest, abdomen, and pelvis.
• Participants who have had brain metastases will be eligible if all of the following are true:
• Each brain metastasis must have been completely removed by surgery or each unresected brain metastasis must have been treated with stereotactic radiosurgery.
• There has been no evident growth of any brain metastasis since the most recent treatment.
• No brain metastasis is > 2 cm in diameter at the time of registration.
• The most recent surgical resections or gamma-knife therapy for malignant melanoma must have been completed ≥ 1 week and for Part 1, ≤ 6 months prior to registration.
• All participants must have:
• ECOG performance status of 0 or 1 (Appendix 3)
• Ability and willingness to give informed consent
• Laboratory parameters as follows:
• ANC > 1000/mm3
• Platelets > 100,000/mm3
• Hgb > 9 g/dL
• HgbA1c ≤ 7.5%
• Hepatic:
• AST and ALT ≤ 2.5 x upper limits of normal (ULN)
• Bilirubin ≤ 2.5 x ULN (except in patients with Gilbert's disease, where bilirubin to 4x ULN is allowed)
• Alkaline phosphatase ≤ 2.5 x ULN

You may not qualify if…

• 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
• High doses of systemic corticosteroids, with the following qualifications and exceptions:
• In patients with adrenal or pituitary insufficiency replacement steroid doses are allowed; however, daily doses of 10 mg or more of prednisone (or equivalent) per day administered parenterally or orally are not allowed in patients with normal adrenal and pituitary function.
• Inhaled steroids (e.g.: Advair®, Flovent®, Azmacort®) are permitted at low doses (less than 500 mcg fluticasone per day, or equivalent) (76,77).
• Topical, nasal, and intra-articular corticosteroids are acceptable.
• Growth factors (e.g. Procrit®, Aranesp®, Neulasta®)
• Interleukins (e.g. Proleukin®)
• Any investigational medication
• Targeted therapies specific for mutated BRAF or for MEK
• Participants who are currently receiving nitrosoureas or who have received this therapy within the preceding 6 weeks
• Participants who are currently receiving a checkpoint molecule blockade therapy, or who have received this therapy within the preceding 12 weeks.
• 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 of childbearing potential must have a negative pregnancy test (urinary or serum beta-HCG) obtained within 2 weeks prior to registration. Males and females must agree, in the consent form, to use effective birth control methods during the course of vaccination.
• 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 (Appendix 4).
• Participants with uncontrolled diabetes, defined as having a HgbA1c ≥ 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. The following will not be exclusionary:
• The presence of laboratory evidence of autoimmune disease (e.g. positive ANA titer) without symptoms
• Clinical evidence of vitiligo
