Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The FRONTIER Study is a prospective, interventional, single-arm, multi-center, study to assess the safety and technical feasibility of TheraSphere GBM in patients with recurrent GBM.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Glioblastoma (GBM) is a highly aggressive brain cancer with a grave prognosis, resulting in \<7% of patients surviving to five years post-diagnosis. External beam radiotherapy (EBRT) is currently a mainstay treatment for GBM; however, the dose delivered is limited by side effects. The targeted radiotherapy of the TheraSphere GBM Y-90 Glass Microsphere System (TheraSphere GBM) has promising potential to provide GBM patients with reduced side effects compared to external beam radiotherapy as well as a more effective treatment for this catastrophic disease.

The TheraSphere GBM device utilized in the FRONTIER trial is an yttrium-90 (Y-90) glass microsphere therapy for selective internal radiation therapy (endovascular radiotherapy) in recurrent GBM patients. The TheraSphere GBM treatment utilizes intra-arterial delivery and takes advantage of blood flow and direct tumor delivery. Treatment can be delivered by specific placement of a catheter close to the tumor through known angiographic techniques currently utilized by neuro-endovascular or interventional radiology physicians. Angiographic evaluation prior to treatment allows identification of tumor feeding arteries and definition of the treatment volume. TheraSphere GBM could achieve a high tumor response rate based on delivery of a tumor absorbed dose that is not currently possible with EBRT.

In consideration of the potential benefit of a more localized, targeted treatment with a reduced side effect profile compared to other treatment options, and the potential impact on patients' quality of life for this devastating disease, this First-in-Human Early Feasibility Study (EFS) of the TheraSphere GBM Y-90 Glass Microsphere System for the treatment of recurrent GBM is being conducted.

Intervention Model

PARALLEL

The TheraSphere GBM Y-90 Glass Microsphere System (TheraSphere GBM) is an yttrium-90 (Y-90) glass microsphere therapy for selective internal radiation therapy (endovascular radiotherapy) in recurrent GBM patients. Groups A, B, and C will be enrolled concurrently. Up to 26 subjects will be enrolled in Groups A and C. Four subjects will be enrolled in Group B. Up to 6 subjects will be enrolled in Group D.

Enrollment in Group D will not begin until the FDA approves an IDE supplement including all data through the primary safety endpoint from the four Group B subjects, as well as any available data from the Group A and C subjects at the time of submission.
