About this study

This is a Phase 3 prospective, randomized, superiority, open-label, multi-site study. The overview of this study is as follows: * A Screening/Baseline Period of 21 days. During this time, patients will be randomized into a 1:2 allocation of Arm A:Arm B. * A Perioperative/Operative Phase where patients will undergo tumor resection (Arm A) or tumor resection plus GammaTile implantation (Arm B). * An EBRT Prior to Start Period. This occurs within 10 business days prior to EBRT and Concurrent TMZ Phase. * An EBRT and Concurrent TMZ Phase, which will begin 30 ±10 days post-surgery. EBRT (30 fractions) and TMZ will be administered up to 5 days a week for 6 weeks in Arm A, and EBRT (20 fractions) and TMZ will be administered for up to 5 days a week for 4 weeks in Arm B. TMZ will be administered at a dose of 75 mg/m2/day orally for each Arm. * An Adjuvant TMZ Phase, which begins 28 ±7 days following the EBRT and Concurrent TMZ Phase, and is comprised of six 28-day cycles. TMZ (150-200 mg/m2/day orally) will be administered for the first 5 days of each 28-day cycle for each Arm. Tumor treating fields are allowed but are not mandated during this phase. Up to 6 additional cycles (for a total of 12) can be completed at the discretion of the Investigator. * An Early Discontinuation/Follow-Up Phase will occur 28 ±7 days after completion of Cycle 6 of the Adjuvant TMZ Phase, regardless of the total number of cycles completed or any delays in cycle start. If fewer than six cycles are comple…
