GammaTile Therapy | STaRT
GammaTile Therapy is a safe and effective Surgically Targeted Radiation Therapy (STaRT) that begins working immediately at the time of brain tumor removal.
FDA-cleared for treating recurrent brain tumors, including meningiomas, metastases, high-grade gliomas, and glioblastomas
Extends survival and delays tumor recurrence for patients with recurrent brain tumors
Patients receive radiation treatment while going about their daily lives
Extended Local Recurrence-Free and Overall Survival
In a clinical study, GammaTile Therapy gave the average patient approximately 10 extra months without a local recurrence with extended overall survival.
Taken as a whole group (across all tumor types in the clinical study), patients who received surgery plus GammaTile Therapy had an approximately 2X improvement in median time to tumor recurrence compared to their most recent prior treatment.[1.*]
The median time to surgical-site brain tumor recurrence was 19.9 months, a 9.7-month improvement across all tumor types in the clinical study.[1.*]
* Tumor types in the clinical study were high-grade gliomas, meningiomas, and brain metastases.
~2X IMPROVEMENT ACROSS ALL
TUMOR TYPES IN THE STUDY
Median local control (LC) after GammaTile Therapy vs prior treatment was 12.0 vs 9.5 months for high-grade glioma (HGG) patients (HR 0.6, p = .13) and 48.8 vs 23.3 months (HR 0.24, p = .01) for meningioma patients. For the metastasis patients, the median LC has not been reached vs 5.1 months with prior treatment (HR .07, p = 0.02). The median overall survival (OS) was 12.0 months for HGG patients, 12.0 months for the brain metastasis patients, and 49.2 months for the meningioma patients.
