Effects of Vaccinations With HLA-A2-Restricted Glioma Antigen-Peptides in Combination With Poly-ICLC for Adults With High-Risk WHO Grade II Astrocytomas and Oligo-Astrocytomas

Summary

This is a pilot vaccine study in adults with either WHO grade II astrocytoma, oligoastrocytoma or oligodendroglioma. The purpose of this study is test the safety and efficacy of an experimental tumor vaccine made from peptides and Montanide ISA-51 in combination with the study drug Poly-ICLC. Poly-ICLC, manufactured by Oncovir, Inc., has already been received and generally well tolerated by subjects in earlier studies and has been shown to decrease the size of brain tumors in some cases. The immunological and safety data will be used to decide whether a larger study of clinical efficacy is warranted in each of two patient cohorts.

Detailed description

All patients on the study will be followed for a minimum of 2 years, so that the actual 2-year overall survival (OS) and progression-free survival (PFS) rates can be determined in an exploratory manner.

Conditions

• Astrocytoma
• Oligo-Astrocytoma
• Glioma

Interventions

Type	Name	Description
BIOLOGICAL	GAA/TT-peptide vaccine and poly-ICLC	Participants will be treated with subcutaneous injections of GAA/TT-vaccines on Weeks 0, 3, 6, 9, 12, 15, 18 and 21. I.m. poly-ICLC will be administered (20 mg/kg i.m.) on the day of, and on day 4 after each vaccine (e.g. if the vaccine is administered on Thursday, poly-ICLC will be administered on the day of vaccine and the following Monday). Each vaccine will be administered within 2 hours before or after the i.m. poly-ICLC administration.
