For Healthcare Providers
Right treatment. Right time. Right place.
GammaTile Therapy is a Surgically Targeted Radiation Therapy
(STaRT) that provides immediate, dose-intense treatment at completion of resection. By getting a head STaRT on fighting the tumor, resection plus GammaTile Therapy extends local
recurrence-free survival with minimal complications, reduced patient burden, and assured compliance.
~2X IMPROVEMENT ACROSS ALL
TUMOR TYPES IN THE STUDY
Outcomes & Safety
GammaTile Therapy extends local recurrence-free survival vs previous standard of care treatment.
Significantly improves outcomes by approximately 2X
across all tumor types in the study
Median time to same-site recurrence was 19.9 months, a 9.7-month improvement across all tumor types
~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.
EXTENDED OVERALL SURVIVAL: RECURRENT HGG[1-3]
Excellent safety profile – designed to limit radiation changes in healthy tissue[1,4-8,*]
*Defined as common terminology criteria for adverse events (CTCAE), Grade 3–5 possibly or probably related to GammaTile Therapy placement occurring at any time during follow-up.
GammaTile Therapy is a safe and effective, Surgically Targeted Radiation Therapy (STaRT) for patients with recurrent brain tumors
Extends local recurrence-free survival with minimal complications
Reduces patient burden and preserves quality of life
Facilitates favorable reimbursement (CMS craniotomy code ICD-10 MS-DRG 023)
Clinical efficacy, immediacy, and efficiency
Enables immediate treatment at resection with no additional hospital stay
Integrates into the surgical workflow for procedural ease and speed
Takes approximately 5 minutes to complete tile placement
Simplifies care with 100% "built-in" compliance and no special inpatient precautions or contraindications with systemic therapies
How It Works. An Eloquent Solution.
GammaTile Therapy targets tumor cells while preserving brain tissue. Surgically guided treatment of the local radiation dose to the operative bed optimizes the therapeutic margin while minimizing complications.
Structural offset of the radiation source from the brain tissue prevents harmful direct seed-to-tissue contact and enables intraoperative adjustment.
Enhanced local control and optimized efficacy
50% of the therapeutic dose is delivered within the first
10 days after surgery, which helps prevent residual tumor cells from replicating
88% of the therapeutic dose is delivered within 30 days, with more than 95% of the dose delivered by 6 weeks
A favorable depth-dose profile optimizes local
Bioresorbable, conformable collagen tile preserves healthy tissue
Provides a structural offset of the radiation source from normal brain tissue
Enforces uniform radiation-source spacing, both within a single tile and between multiple tiles
Minimizes local hot and cold spots
Facilitates rapid, accurate placement to deliver a predictable radiation dose
“What I like about GammaTile is that they’re taking a radiation technology that already exists and making it safer and easier to deliver…Should be equally effective and faster to implant after tumor surgery…[It’s] better for patients (less anesthesia time) and safer for the staff (less exposure in the operating room).”
