Clinical Trial Title A Safety Run-In and Phase II Study Evaluating the Efficacy, Safety, and Impact on the Tumor Microenvironment of the Combination of Tocilizumab, Atezolizumab, and Fractionated Stereotactic Radiotherapy in Recurrent Glioblastoma
Trial Status Open to Enrollment
Start Date 01/24/2022
Location hospitals
Trial Type Cancer - Adult Oncology
Specific Condition Brain Tumor
Description This phase II trial studies the best dose and effect of tocilizumab in combination with atezolizumab and stereotactic radiation therapy in treating glioblastoma patients whose tumor has come back after initial treatment (recurrent). Tocilizumab is a monoclonal antibody that binds to receptors for a protein called interleukin-6 (IL-6), which is made by white blood cells and other cells in the body as well as certain types of cancer. This may help lower the body's immune response and reduce inflammation. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Fractionated stereotactic radiation therapy uses special equipment to precisely deliver multiple, smaller doses of radiation spread over several treatment sessions to the tumor. The goal of this study is to change a tumor that is unresponsive to cancer therapy into a more responsive one. Therapy with fractionated stereotactic radiotherapy in combination with tocilizumab may suppress the inhibitory effect of immune cells surrounding the tumor and consequently allow an immunotherapy treatment by atezolizumab to activate the immune response against the tumor. Combination therapy with tocilizumab, atezolizumab and fractionated stereotactic radiation therapy may shrink or stabilize the cancer better than radiation therapy alone in patients with recurrent glioblastoma.
Eligibility Criteria

Eligibility Criteria

  • Age ≥ 18 years.
  • Karnofsky performance status ≥70 within 14 days prior to registration.
  • Histopathologically proven diagnosis of glioblastoma, OR molecular diagnosis of glioblastoma
  • Unequivocal radiographic evidence of tumor progression by contrast-enhanced magnetic resonance imaging (MRI) scan within 21 days prior to registration

Ineligibility Criteria

  • Known somatic tumor mutation in IDH1 or IDH2 gene.
  • Known germline DNA repair defect (mismatch repair deficiency, POLE mutation, e.g.). If not previously completed, germline sequencing is not required to determine trial eligibility.
  • Prior bevacizumab therapy.
