Trial FAQ

  • Which treatment will I receive after brain tumor removal surgery?
    All clinical trial participants will receive both GammaTile® Therapy and the Stupp protocol.
  • What is the Stupp protocol?
    Named after its founder, the Stupp protocol consists of external beam radiation therapy (EBRT) and oral chemotherapy with Temodar®, also called temozolomide, or TMZ.[1] EBRT is delivered to the brain tumor or the area where the brain tumor was removed. Radiation and chemotherapy are combined to optimize treatment results.[1]
  • Will receiving 2 radiation therapies be too much radiation for me?
    No, the total radiation administered in this clinical trial from both GammaTile Therapy and EBRT is within standard radiation treatment levels.
  • Can I participate if I am receiving other therapies?
    In many cases, yes. Previous or ongoing treatment with chemotherapy, targeted therapeutics, and immunotherapy is permitted, though it must comply with the specific clinical trial guidelines.
  • Will participating in this clinical trial delay my surgery?
    Participation may not delay your tumor removal surgery, but you must qualify and enroll about a week before your surgery. That’s why you should contact your participating hospital as soon as possible if you wish to enroll in this clinical trial.
  • I’ve scheduled my surgery already—is it too late to participate in this clinical trial?
    If your surgery has been scheduled at a GESTALT Clinical Trial–participating hospital and it’s about a week away, you may still be able to participate in the clinical trial. Please contact the GESTALT Clinical Team ASAP to schedule an appointment. If your surgery is scheduled at a nonparticipating hospital, you may be eligible for a second opinion at a GESTALT Clinical Trial–participating hospital before your surgery.
  • Can I receive additional investigational drugs if I join this clinical trial?
    Possibly, depending on the investigational drug, the clinical trial, and its exclusions. Please discuss this with your GESTALT Clinical Team and your medical care team.
  • Will I receive the same treatments that other patients like me receive outside of the clinical trial?
    Yes, the Stupp protocol standard of care is commonly used for patients with glioblastomas. In addition, you will receive FDA-cleared GammaTile Therapy. Further you will have the added benefit of the GESTALT Clinical Team closely overseeing your care.
  • Will my health insurance cover my treatments if I participate?
    Health insurance usually covers the cost of these FDA-cleared treatments. The GESTALT Clinical Team will confirm your insurance coverage before your enrollment.
  • Will I be paid to participate?
    Clinical trial participants at some, but not all, participating hospitals may be paid up to $50 per clinical trial visit. Ask your GESTALT Clinical Team for details.
  • How do I enroll in the clinical trial?
    Prior to your brain tumor removal surgery: Schedule an appointment with the GESTALT Clinical Team to confirm that you qualify for the clinical trial and to take the screening tests. Sign the informed consent form. Take a pregnancy test if you are a female of childbearing age. Answer a questionnaire about your quality of life. Take some brain function assessments. Next, the GESTALT Clinical Team will schedule your surgery, and you will be on track to receive your treatments. The first follow-up visit will be 28 +3 days after the start of cycle 4 of adjuvant temozolomide. Follow-up visit frequency will be: Every 2 months +14 days for the first year Every 4 months +21 days from 13 months after the first day of the last TMZ cycle At 36 months from surgery
