Stereotactic Radiosurgery With Nivolumab and Valproate in Patients With Recurrent Glioblastoma

26. mai 2017 oppdatert av: Benjamin Purow, MD, University of Virginia

A Pilot Study to Evaluate the Feasibility of the Combined Use of Stereotactic Radiosurgery With Nivolumab and Concurrent Valproate in Patients With Recurrent Glioblastoma

The purpose of this study is to evaluate the safety and feasibility of the immunotherapeutic agent nivolumab given in combination with gamma knife therapy and valproate in patients with recurrent glioblastoma, a common and lethal type of brain cancer.

Detaljert beskrivelse

Immune checkpoint inhibitors have the potential to treat a wide range of diverse cancers. Of particular interest to researchers is the PD-1 receptor-ligand interaction, a major pathway that many cancers hijack in order to suppress immune control. Anti-PD-1 antibodies such as nivolumab show a strong potential to treat many types of cancers including glioblastoma, the most common and most lethal brain cancer.

This study will examine a means of further focusing immune response on glioblastoma by combining stereotactic "gamma knife" radiosurgery with nivolumab. The rationale behind this intervention is that the radiation therapy will enhance immune response rate by providing additional tumor antigens from dying cells. Additionally, a study from investigators at Johns Hopkins indicates that histone deacetylase (HDAC) inhibitors may boost the anti-cancer efficacy of PD-1 antibodies like nivolumab. Valproate, a class I HDAC inhibitor, will be used concurrently with nivolumab with the goal of enhancing the effects of both the nivolumab and the radiotherapy.
