May 2, 2022 updated by: Antti Kaipia, Tampere University Hospital

3D Versus Robot Assisted Laparoscopic Prostatectomy. A Prospective Randomized Non-inferiority Study.

A randomized, prospective study to compare the direct and indirect costs, functional and oncologic results of 3D laparoscopic and robot assisted radical prostatectomy procedures.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The direct and indirect costs, functional and oncologic results of robot assisted radical prostatectomy (RALP) are compared to those of 3D laparoscopic radical prostatectomy. The hypothesis of the study is that the functional and oncologic results of the two operative methods are equal, but the direct costs of RAPL are significantly higher. A randomized, prospective non-inferiority study will will enroll 280 patients randomized 1:1 to both operative approaches to test this hypothesis. The primary functional outcome measure is the proportion of patients with complete urinary continence (no protective pad use) at 12 months post operatively. Secondary functional outcome measure is the preservation erectile function at 12 months post operatively. Oncologic outcome measures are the proportion of patients with undetectable post operative prostate specific antigen levels and positive surgical margins at pathological examination. The direct and indirect costs of both operative approaches are recorded.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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.

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
Urinary continence
Time Frame: 12 months
Expanded Prostate Cancer Index Composite (EPIC) Short Form (EPIC-26), urinary domain score is used to assess the return of continence post operatively. The percentage of patients with no protective pad use at 12 months post operatively is the main outcome measure.
12 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Erectile function
Time Frame: 12 months
International Index of Erectile Function (IIEF-5) Questionnaire score is used to quantify the return of erectile function post operatively.
12 months
Prostate specific antigen
Time Frame: 12 months
Post operative prostate specific antigen levels.
12 months
Evaluation of surgical margins at pathologic examination.
Time Frame: up to 12 months
The oncological outcome is evaluated by the presence of cancerous tissue at the surgical margins of the specimen at pathologic examination.
up to 12 months

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.
