A Multicenter Trial to Evaluate the Effects of Administration of Cyclophosphamide and Melanoma-Derived Helper Peptides on the Immunogenicity of a Class I MHC-Restricted Peptide-Based Vaccine in Participants With Resected Melanoma


OBJECTIVES:

Primary

- Determine the safety of adjuvant vaccine therapy comprising multi-epitope melanoma
peptides (MP) and multi-epitope melanoma helper peptides (MHP) emulsified in Montanide
ISA-51 in patients with resected stage IIB-IV melanoma.

- Determine the safety of administering cyclophosphamide before vaccination in these
patients.

- Compare the magnitude of immune response against vaccination comprising MP in
combination with either MHP or tetanus toxoid helper peptide (TET) emulsified in
Montanide ISA-51 with vs without cyclophosphamide in these patients.

Secondary

- Compare the response rate and persistence of immune responses in patients treated with
these regimens.

- Compare the magnitude of immune response against vaccination comprising TET or MHP with
vs without cyclophosphamide in these patients.

- Compare the response rate and persistence of immune response against vaccination
comprising TET or MHP with vs without cyclophosphamide in these patients.

- Determine the delayed-type hypersensitivity response to the peptide components of these
vaccines in these patients.

- Compare, preliminarily, disease-free survival of patients treated with these regimens.

OUTLINE: This is a randomized, open-label, multicenter study. Patients are stratified
according to HLA-type (HLA-A1 positive vs HLA-A2 positive, HLA-A1 negative, or -A3 negative
vs HLA-A3 positive, or -A1 negative) and participating center (University of Virginia [UVA]
vs non-UVA). Patients are randomized to 1 of 4 treatment arms.

- Arm I: Patients receive vaccine comprising multi-epitope melanoma peptides (MP) and
tetanus toxoid helper peptide emulsified in Montanide ISA-51 intradermally (ID) and
subcutaneously (SC) on days 1, 8, 15, 29, 36, 43, 85, 183, 274, and 365.

- Arm II: Patients receive cyclophosphamide IV over 30-60 minutes on day -4. Patients
then receive vaccine as in arm I.

- Arm III: Patients receive vaccine comprising MP and multi-epitope melanoma helper
peptides emulsified in Montanide ISA-51 ID and SC on days 1, 8, 15, 29, 36, 43, 85,
183, 274, and 365.

- Arm IV: Patients receive cyclophosphamide as in arm II. Patients then receive vaccine
as in arm III.

Treatment in all arms continues in the absence of disease progression or unacceptable
toxicity.

After completion of study treatment, patients are followed every 6 months for 2 years and
then annually thereafter.

PROJECTED ACCRUAL: A total of 173 patients will be accrued for this study within 2 years.
