Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.
|Eligible Ages||18 Years and Over|
- - Age >18 years - Patient with high-grade glioma considered for external beam radiotherapy (15 fractions or more) with or without Temozolamide, or patients with brain metastases considered for fractionated LINAC-based external beam radiotherapy (5 fractions or more) as primary or adjuvant treatment.
- - No contraindications to MRI - No other medical conditions deemed by the PI to make patient ineligible for the study (i.e. claustrophobia, confusion, delirium).
Exclusion Criteria:- None
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.
|University Health Network, Toronto|
The person who is responsible for the scientific and technical direction of the entire clinical study.
|Principal Investigator Affiliation||N/A|
Category of organization(s) involved as sponsor (and collaborator) supporting the trial.
|Overall Status||Not yet recruiting|
The disease, disorder, syndrome, illness, or injury that is being studied.
All patients referred for radiotherapy have had a previous diagnostic imaging study (CT-scan or more commonly MRI) showing the disease at the central nervous system (CNS). Moreover, after surgical biopsy or resection, many Centers perform repeated post-operative imaging. Despite all prior imaging, when radiotherapy treatment is decided, all patients undergo another imaging study (CT simulation [CT-sim]) in which patient's head is placed in a reproducible position, and endure a moulding procedure to create a personalized plastic mask for securing the patient's head in a fixed position during the CT acquisition, and reproduced at the subsequent radiation treatment sessions. Typical wait times between moulding, CT-sim and the first radiation treatment is 3-7 days. If a method would be available to accurately recreate the patient's position during diagnostic imaging and reproduce it during radiation treatments without the need for a moulding session or CT-sim, the treatment process can be streamlined and wait times shortened for patients. Previous studies using 3D printing technology in radiotherapy (such as brachytherapy applicators) have shown that these employed materials are safe for use in clinical settings, and 3D printers can accurately produce devices of various shapes and sizes for clinical use. In this study, we propose a novel workflow in which patient's position at diagnostic imaging is reproduced with a 3D-printed patient-specific immobilization device, enabling the use of the same diagnostic imaging for planning purposes in lieu of dedicated simulation and moulding sessions, to decrease wait times for patients between diagnostic imaging and start of radiation treatment.
