Study Details

This is open label, multicentre, single arm, pilot study of upfront nivolumab in patients with RRD-glioblastoma with favorable immune/genomic biomarkers. The purpose of the study is to use upfront immune checkpoint inhibitor (ICI) to delay/avoid radiation for patients with RRD-glioblastoma with favorable clinical (Gross total resection (GTR) or near total resection (NTR)) and biological (RRD, hypermutation, immune activation) biomarkers. At progression, patients will be undergoing surgery/biopsy and will get a combination of radiation + ICI followed by maintenance ICI. This model will allow us to additionally study the evolution tumor in response to ICI. The study will have two domains.

Arms

  • Active Comparator: Domain 1 - Upfront ICI
    Initially 12 eligible patients will be enrolled for upfront ICI. At 12 week assessment if \>6 patients have response (NO radiation for recurrence/progression), an additional 6 patients will be enrolled for upfront ICI. All patients will be assessed at 12 weeks from the start of ICI. If 6 or fewer patients have response (NO radiation for progression/recurrence), no more patients will be recruited to this domain.
  • Active Comparator: Domain 2 - Radiation + ICI → maintenance ICI
    All the patients experiencing tumor progression on domain 1 will be eligible for domain 2 and will receive a combination of radiation and nivolumab followed by maintenance nivolumab for 2 years. To be eligible for domain 2 post recurrence patients will need surgery/biopsy at recurrence. If 6 RRD-glioblastoma will recur/progress at 12 weeks on domain 1 then 8 additional eligible patients may be directly enrolled in domain 2.

Primary Outcome Measure

To evaluate Radiation-free survival (RFS) from start of immunotherapy [ Time Frame: 2 years ]
