Study of Peptide Vaccination With Tumor Associated Antigens Mixed With Montanide in Patients With CNS Tumors
This is an open-label, single arm study evaluating a multi-peptide (tumor-associated antigens)/Montanide vaccine in patients < 21 years of age with recurrent or refractory CNS tumors. The study primarily evaluates the safety of this regimen. Secondarily, immunogenicity and anti-tumor effects will be assessed.
The primary aim is to evaluate the safety of subcutaneous injections of tumor associated antigens (TAA) mixed with Montanide ISA-51VG in patients with recurrent or refractory brain tumors.
The secondary aims are to evaluate cellular immune responses induced in patients after subcutaneous injection of TAA mixed with Montanide ISA-51VG and to document tumor response in patients with measurable disease or time to progression in patients without measurable disease following subcutaneous injection of TAA mixed with Montanide ISA-51VG.

Montanide is an oil-based immunoadjuvant similar to Incomplete Freund´s Adjuvant, which is commonly used in combination with peptide vaccines. Although its precise mode of action is not known, it acts to enhance the immune response to vaccination. It has a depot effect that depending on the type of emulsion will release the antigen slowly from the injection site.
Other Name: Montanide ISA-51 VG
