Filter by:This is a prospective case-control study. This study is expected to last for approximately 12 months, comprised of 4-8 weeks of enrollment period, 28 days of treatment and 6 months of follow up. The enrollment will be completed prior to the beginning of initial treatment. The study will be closed when 10 subjects have completed the study. The recruitment will be carried out with a sample at convenience.
The early clinical development paradigm for chemotherapeutic agents has significantly influenced the development of therapeutic cancer vaccines. However, there are major differences between these two classes of therapeutics that have important implications for early clinical development. Specifically, the phase 1 concept of dose escalation to find a maximum-tolerated dose does not apply to most therapeutic cancer vaccines. Most therapeutic cancer vaccines are associated with minimal toxicity at a range that is feasible to manufacture or administer, and there is little reason to believe that the maximum-tolerated dose is the most effective dose. In a recent article from the biostatistics literature, Simon et al. write that "the initial clinical trial of many new vaccines will not be a toxicity or dose-ranging trial but rather will involve administration of a fixed dose of vaccine … in most cases the dose selected will be based on preclinical findings or practical considerations. Using several dose levels in the initial study to find the minimal active dose or to characterize the dose-activity relationship is generally not realistic". Consistent with these recommendations, the general philosophy of the phase 1 clinical trial is to facilitate a prompt preliminary evaluation of the safety and immunogenicity of the personalized synthetic long peptide vaccine strategy. The proposed clinical trial will test a fixed dose of vaccine. There is considerable experience with the synthetic long peptide vaccine platform. The synthetic long peptide vaccine platform has an excellent safety profile, and the optimal dose appears to be based on practical considerations (solubility of the peptide). The dose to be tested in the proposed clinical trial is consistent with other similar cancer vaccine trials that have been recently completed or are currently ongoing. The sample size (n=10-20) will provide a reasonably reliable estimate of the safety and immunogenicity of the vaccine.
The study investigates valproic acid added to radiation and temozolomide therapy (standard of care) for progressive or recurrent pediatric brain tumors.
