December 1, 2020 updated by: PROCEPT BioRobotics

The UK POST WATERStudy: UK Post-market Waterjet Ablation Therapy for Endoscopic Resection of Prostate Tissue

A post-market, non-interventional, two-arm, long-term follow-up study of patients previously enrolled in the WATER Study (NCT02505919) - which was a prospective multi-centre randomized blinded study comparing Aquablation of the prostate with the AQUABEAM Robotic System with standard transurethral resection of the prostate (TURP) for the treatment of lower urinary tract symptoms (LUTS).

Detailed Description

The study is a post-market, non-interventional, two-arm, long-term follow-up study of patients previously enrolled in the WATER Study (NCT02505919) - which was a prospective multi-centre randomized blinded study comparing Aquablation of the prostate with the AQUABEAM Robotic System with standard transurethral resection of the prostate (TURP) for the treatment of lower urinary tract symptoms (LUTS). In POST WATER, up to 46 WATER Study subjects in the United Kingdom who were active on the study at 36 months will be invited to participate, across 3 clinical study sites in England and Wales. The study will consist of one follow-up time-point at 60 months (5 years) from the time of initial WATER Study treatment date.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

45 years to 85 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

N/A

Genders Eligible for Study

Male

Sampling Method

Non-Probability Sample

Study Population

The target patient population is subjects who were enrolled in the WATER Study (with symptomatic BPH) who were randomized to treatment with either the Aquablation procedure or TURP.

Description

Inclusion Criteria:

  1. Subject was randomized and received treatment in the WATER Study.
  2. Subject is mentally capable and willing to sign a study-specific informed consent form

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
WATER AQUABEAM Robotic System cohort
WATER Study subjects previously-treated with Aquablation of the prostate with the AQUABEAM Robotic System for lower urinary tract symptoms associated with BPH.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Long-term effectiveness as measured by IPSS at 60 months
Time Frame: 60 months following original surgical intervention
International Prostate Symptom Score at 60 months as compared to baseline
60 months following original surgical intervention
Long-term safety as measured by adverse events at 60 months
Time Frame: 60 months following original surgical intervention
The proportion of subjects with adverse events classified as Clavien-Dindo Grade 2 or higher or any grade 1 event resulting in persistent disability
60 months following original surgical intervention

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.

Study Major Dates

Study Start (ANTICIPATED)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
January 1, 2021

Primary Completion (ANTICIPATED)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
