What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests a new robotic tool called the EndoR Surgical System for removing early-stage colorectal lesions. The goal is to see if it can make the procedure safer and more effective than current methods. Six adults aged 18 to 85 with superficial colorectal lesions will take part. The system aims to give surgeons better control and precision, which may reduce complications like bleeding or perforation.

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 6 people

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

Started

Jan 2026

Expected to finish

Jun 2028

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.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 to 85 years

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Show the full entry requirements

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

Inclusion Criteria: * Aged between 18 and 85. * Patient with superficial colorectal lesions, scheduled for endoscopic submucosal dissection (ESD). According to the European Society of Gastrointestinal Endoscopy (ESGE) and the Japan Gastroenterological Endoscopy Society (JGES) guidelines for colorectal ESD: i. Lesions for which en bloc resection with snare EMR would be difficult to apply; ii. Mucosal tumors with submucosal fibrosis; iii. Sporadic tumors in conditions of chronic inflammation; iv. Local residual or recurrent early carcinomas after endoscopic resection. Exclusion Criteria: * No informed consent available. * Carcinoma of colon or rectum with invasion to submucosa or beyond. * Evidence of distant metastasis. * Another active malignancy present. * Pregnant. * Patients are unfit for general anesthesia. * The target lesion that could not be reached by the endoscopic platform. * Have been recruited in another clinical trial.
