A Multipeptide Vaccine Plus Toll-Like Receptor Agonists in Melanoma Patients

Completed · Phase 1

Conditions studied: Melanoma

In brief

The purpose of this study is to learn the effects an experimental vaccine (MELITAC 12.1) combined with other substances called lipopolysaccharide (LPS; endotoxin), polyICLC, and Montanide ISA-51. The LPS, polyICLC, and Montanide ISA-51 are included with the vaccine to test whether they have an effect on the MELITAC 12.1 vaccine. The study will also look at whether the experimental vaccine and these drugs cause any changes to the immune system.

Who can join

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

You may qualify if…

• Histologically or cytologically proven melanoma that meets one of the following two criteria:
• Stage IIB-IV melanoma rendered clinically free of disease by surgery, other therapy, or spontaneous remission within 6 months prior to registration.
• Stage III or IV melanoma with disease. Patients may be eligible if there are definite or equivocal findings of persistent or metastatic disease as long as those findings do not meet RECIST criteria for measurable disease.
• Patients with brain metastases may be eligible if all of the following are true:
• The total number of brain metastases ever is less than or equal to 3.
• The brain metastases have been completely removed by surgery or have been treated completely by stereotactic radiotherapy. Stereotactic radiotherapy, such as gamma knife, can be used up to 1 week prior to study entry.
• There has been no evident growth of any brain metastasis since treatment.
• No treated brain metastasis is greater than 2 cm in diameter at the time of protocol entry.
• Patients must have at least two intact axillary and/or inguinal lymph node basins.
• All patients must have:
• ECOG performance status of 0 or 1.
• Ability and willingness to give informed consent.
• Laboratory parameters as follows:
• HLA-A1, A2, A3, -A11, or -A31
• ANC > 1000/mm3
• Platelets > 100,000/mm3
• Hgb ≥ 9 g/dL
• AST and ALT ≤ 2.5 x upper limits of normal (ULN)
• Bilirubin ≤ 2.5 x ULN
• Alkaline Phosphatase ≤ 2.5 x ULN
• Creatinine ≤ 1.5 x ULN
• HIV negative
• Hepatitis C negative
• HGBA1C level of < 7%

You may not qualify if…

• Patients who have had brain metastases, unless they meet inclusion criteria
• Patients who are currently receiving systemic cytotoxic chemotherapy, radiation, or other experimental therapy, or who have received this therapy within the preceding 4 weeks. Gamma knife or stereotactic radiosurgery may be administered within the prior 4 weeks, but must not be administered less than one week prior to study enrollment. Patients who are currently receiving nitrosoureas or who have received this therapy within the preceding 6 weeks.
• Patients with clinically detectable melanoma deemed likely by the investigator to require intervention during the first 12 weeks of the study that would require premature discontinuation.
• Patients with known or suspected allergies to any component of the vaccine.
• Patients receiving the following medications at study entry or within the preceding 4 weeks are excluded:
• Agents with putative immunomodulating activity (with the exception of non-steroidal anti-inflammatory agents and topical steroids
• Allergy desensitization injections.
• Systemic corticosteroids, administered parenterally or orally. Inhaled steroids (e.g. Advair®, Flovent®, Azmacort®) are not permitted. Topical corticosteroids are acceptable, including steroids with very low solubility administered nasally for local effects only (e.g. Nasonex®).
• Any growth factors (e.g. GM-CSF, G-CSF, erythropoietin).
• Interferon therapy.
• Interleukin-2 or other interleukins.
• Toll-like receptor agonists, including imiquimod or resiquimod.
• Prior melanoma vaccinations may be an exclusion criterion in some circumstances:
• Patients who have recurred or progressed either after or during administration of a melanoma vaccine may be eligible to enroll 12 weeks following their last vaccination.
• Patients may have been vaccinated previously with peptide vaccines (except that they may not have been vaccinated with peptides included in MELITAC 12.1 or MELITAC 12.6)
• Patients may have been vaccinated with protein, DNA, or cell-based vaccines that include the proteins from which these peptides are derived.
• Other investigational drugs or investigational therapy if the patient is currently taking those drugs/therapy, or if they have received the drugs/therapy within 1 month.
• Pregnancy or the possibility of becoming pregnant during vaccine administration. Women must also not be breast feeding.
• Patients in whom there is a medical contraindication or potential problem in complying with the requirements of the protocol, in the opinion of the investigator.
• Patients classified as having Class III or IV heart disease according to the New York Heart Association
• Body weight < 110 lbs
• No active or prior autoimmune disorders requiring cytotoxic or immunosuppressive therapy, or autoimmune disorders with visceral involvement. The following will not be exclusionary:
• The presence of laboratory evidence of autoimmune disease (e.g. positive ANA titer) without associated symptoms
• Clinical evidence of vitiligo
• Other forms of depigmenting illness
