Questions about this trial
What is this clinical trial studying?
An observational study of PRP, run by Harrison, Theodore, M.D..
The full registered description is in the About this study section and the official record.

Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 24 Jul 2025. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Theodore E Harrison, MD (+1 250-655-4178, teh@rejuvacare.org), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Platelet yield (time frame: 5 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Jul 2025.
