NCT ID NCT07580196

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study looks at men with high-risk prostate cancer that appears on only one side of the prostate. During robotic surgery to remove the prostate, doctors will either remove lymph nodes from both sides of the pelvis or just the side with cancer. The goal is to see if removing fewer lymph nodes reduces side effects and recovery time without raising the risk of cancer coming back. About 820 men will take part.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 820 people

The number the study aims to enrol. It can still change while the study runs.

Started

Mar 2026

Expected to finish

Dec 2030

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Male patients aged 18 years or older * Histologically confirmed unilateral high-risk localized prostate cancer, defined by at least one of the following: ISUP Grade Group 4 or 5; suspicion of at least cT3a disease on multiparametric MRI and/or PSMA PET; or PSA greater than or equal to 20 ng/mL with a unilateral index lesion * Unilateral features of the index lesion defined by biopsy, multiparametric MRI, and PSMA PET * No PSMA PET-positive pelvic lymph nodes contralateral to the dominant side of the prostate cancer * No significant contralateral PSMA uptake on the non-dominant side, defined as lesions with PRIMARY score 3 to 5 * No contralateral index lesion on multiparametric MRI subsequently confirmed by prostate biopsy * No high-risk histology on the side contralateral to the dominant lesion, including ISUP Grade Group greater than 3 or unconventional prostate cancer histology * No frank extracapsular invasion or seminal vesicle invasion on the contralateral side * Up to two positive systematic cores with unfavorable intermediate-risk disease or up to four with favorable intermediate-risk disease are allowed on the contralateral side * A maximum of two pelvic PSMA-positive lymph nodes allowed on the dominant side * Clinically localized disease, defined as less than cT4 on multiparametric MRI and no distant metastases, including no retroperitoneal lymph nodes on PSMA PET * Life expectancy greater than 10 years according to physician judgment * Scheduled for robot-assisted radical prostatectomy and fit for surgery * Written informed consent provided Exclusion Criteria: * Any prostate cancer treatment prior to prostatectomy, including androgen deprivation therapy, neoadjuvant chemotherapy, radiotherapy, or focal ablative therapy * Prior active treatment for prostate cancer * Contralateral ISUP Grade Group 4 to 5 prostate cancer * Contralateral ISUP Grade Group 2 in more than 4 positive cores or ISUP Grade Group 3 in more than 2 positive cores * Contralateral cT3 disease on multiparametric MRI * N1 or M1 disease on PSMA PET or multiparametric MRI, except for up to two positive pelvic lymph nodes on the dominant side * No systematic prostate biopsies performed, with a minimum of 10 cores, and targeted biopsies when a target lesion is present * Other active malignancy * Contraindication to multiparametric MRI and/or PSMA PET * Inability to provide written informed consent * Age younger than 18 years * ASA score greater than 3 * Any contraindication to pelvic lymph node dissection * Severe psychiatric disease * Inadequate hematologic and/or coagulation function * Active infection * Any other serious medical, psychiatric, psychological, familial, or geographic condition that, in the judgment of the investigator, may interfere with staging, treatment, follow-up, compliance, or increase treatment-related risk * Patients with prior malignancy treated with curative intent are eligible only with mandatory approval by the local multidisciplinary tumor board
