This registry will capture data on patients undergoing customized transurethral
ultrasound ablation (TULSA) as part of their routine clinical care. The aim of collecting
such data is to further evaluate real-world outcomes of safety and efficacy of this
treatment. The collection of this data is intended to form an evidence-base from which
conclusions can be drawn on how to optimize outcomes to improve patient care and QOL, and
further expand on knowledge of practice trends and treatment costs.
The primary safety objective is to estimate the rate of complications attributable to the
TULSA Procedure. The primary efficacy objective is estimating the proportion of patients
who are free from primary treatment failure after the TULSA Procedure.
Patients being offered TULSA Procedure will be invited to participate in the registry.
Patients who have already undergone TULSA will also be allowed to join the registry.
Hundreds to thousands of patients across sites in US, Canada and Europe will be followed
as per routine clinical care at 3 months, 6 months, 12 months, 2 years, 3 years, 4 years,
5 years and annually lifelong thereafter. Patients will remain active in the registry
until they voluntarily withdraw or die. At each visit, patients will complete a set of
questionnaires that is sent to them by email.
- Informed consent will be collected prior to enrolling the patient into the Registry.
- Initial baseline information will be collected (eg. demographics, medical history,
concomitant medication, prostate MRI, prostate biopsy, PSA, and QOL Questionnaires)
- TULSA Procedure treatment assessment and complications will be collected from clinic
records from treatment day. Optional financial tracking information may also be
collected if patient consents to this portion of the registry.
- At follow-up visits, a set of data points will be collected (eg. PSA, complications,
QoL Questionnaires, survival assessments, and optional financial tracking
information)
All Registry data will be collected and stored in an electronic database capture system
called Castor. Castor is validated and compliant with all applicable laws and
regulations, including ICH E6 GCP, 21 CFR Part 11, EU annex II, General Data Protection
Regulation (GDPR), HIPAA (US), ISO 9001 and ISO 27001. Only sites and sponsor personnel
will have access to the database. On site and/or remote study monitoring will be
undertaken to check source documents and accuracy of data entry. All reasonable methods
will be used to try to minimize missing data, however, some missing data is expected to
occur. No interpolation of missing data will occur. Standard descriptive statistics,
including the mean, standard deviation, median, range, proportion and frequency, will be
used throughout to summarize results. Measures will be presented, and 95% confidence
intervals will be constructed for selected measures, such as efficacy and safety. As a
primarily descriptive study, analyses will be performed at the p=0.05 level of
significance and exact analyses will be used wherever possible.
