Clinical Trial Summary

The purpose of this study is to determine the safety and tolerability of PVX-410, (a cancer vaccine), treatment regimen for patients with smoldering multiple myeloma as a single agent and in combination with lenalidomide.

Description:

This is a dose escalation, phase 1/2a study to assess the safety and tolerability of PVX-410, (a multi-peptide cancer vaccine), treatment regimen in patients with smoldering multiple myeloma as a single agent and in combination with lenalidomide.. Approximately 22 patients will receive six (6) bi-weekly, subcutaneous injections of PVX-410 for a total of twelve (12) weeks of treatment. Safety will be monitored throughout the study. Tolerability, immunogenicity and clinical response will also be measured as described in the protocol.
