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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests a new robotic system (Intilume) for removing early-stage rectal tumors through the body's natural openings, avoiding incisions. Ten adults with non-cancerous or early cancerous growths in the rectum will be treated. The goal is to see if the robot makes the procedure safer, easier, and more effective than current tools.

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 10 people

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

Expected to start

Apr 2026

An estimate. Start dates often move.

Expected to finish

Apr 2027

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 years and older

Sex

Anyone

Healthy volunteers

Not accepted

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

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

Inclusion Criteria: * Patients diagnosed with nonpedunculated early rectal neoplasms \>/= 2 cm in size in the rectum (\>/= 3 cm and \</= 18 cm from the anal verge) that are deemed not feasible for en bloc resection with conventional polypectomy or endoscopic mucosal resection (EMR) as judged by two experienced endoscopists * American Society of Anesthesiologists (ASA) grading I-III * Informed consent available Exclusion Criteria: * Presence of endoscopic signs of massive submucosal invasion (including excavated/depressed morphology, Kudo's pit pattern Type V, or Sano's capillary pattern Type IIIB) * Evidence of deep invasion on endorectal ultrasonography * Unfavorable histopathologic features on biopsy (mucinous cancer, poor differentiation, or gross submucosal invasion) * Patients with other synchronous colorectal neoplasms in addition to the index neoplasm that are indicated for surgical resection * Patients with recurrence from previous EMR or ESD * Patients with non-correctable coagulopathy * Patients with contraindications to general anesthesia * Vulnerable population (e.g., mentally disabled, pregnancy.)
