Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Patients who undergo maximum safe resection of intracranial neoplasm(s) AND implantation of GammaTiles.
- Willing and able to provide informed consent and to participate in all evaluations.
Exclusion criteria
- Inability to undergo pre-operative and post-operative imaging for disease and implant assessment.
- Major medical or psychiatric illness, which, in the investigator's opinion would prevent completion of treatment, ability to complete assessments at the time of enrollment, and/or interfere with follow ups.
- Subjects who, in the investigator's opinion, are unable to understand the protocol or to give informed consent, have a history of poor cooperation, noncompliance with medical treatment, or difficulty in returning for follow up care. A legally authorized representative may provide consent if the potential subject lacks the capacity to provide consent themselves.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
