Study summary

A Feasibility Study to Evaluate Safety and Probable Benefit of the Eclipse XL1 System for Distraction Enterogenesis in Adult and Pediatric Patients with Short Bowel Syndrome

Read the detailed description

This clinical investigation is a study to evaluate safety and probable benefit of the Eclipse XL1 System in pediatric and adult subjects with short bowel syndrome. This study is a single arm study and will enroll subjects ages 3 months to 65 years old at up to 10 study sites in the United States. This study will be open label; treatment allocation will be known by the subjects, the Principal Investigator and his medical staff. Recruitment is expected to occur over the course of 24-36 months.

Device placement will be administered during a standalone procedure or a previously planned procedure that is otherwise needed by the study subject. Subjects may receive up to 2 devices at one time and/or have multiple procedures over time based on clinical necessity Study objectives will be monitored by reviewing patient nutrition, weight, and stool assessment data. The study device will also monitored by radiographic examination to confirm location of the device and assess the safety and probable benefit of distraction enterogenesis until the device is removed or passes out of the intestine naturally. Patients will be followed while the study device is in situ and at 3 and 6 months post device passing or removal. Subjects may or may not be discharged from the hospital while participating in the study, and investigators may recommend that a subject stay in-patient for a portion or the entire length of study, depending on subject health.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Subject has short bowel syndrome, defined as 50% or less of expected bowel length based on subject age and/or height, and measured at the time of the subject's prior intestinal resection.
  • Minimum residual bowel length of 3 cm.
  • Male or female patients aged 3 mo to 65 years inclusive
  • The subject, parent or legal guardian of the subject is able to read, understand, and is willing to provide .
  • The subject or parent or legal guardian of the patient is able to understand the requirements of the study and is willing to bring the subject to all clinic visits and complete all study related procedures (as determined by the investigator).

Exclusion criteria

Exclusion Criteria:

  • Ultra-short bowel syndrome defined as less than 3 cm of bowel length.
  • Diagnosed Inflammatory bowel disease-unclassified (not Crohn's or ulcerative colitis)
  • Evidence of active or prior Crohn's disease.
  • Primary intestinal failure (i.e., without loss or resection of intestinal tissue).
  • Coagulopathy, as defined by > 1.4 or \< 100.
  • Known status including, but not limited to, individuals who have undergone organ transplantation, chemotherapy or radiotherapy within the past 12 months, who have leukopenia, who are positive for the (HIV) or whose immune status makes the subject a poor candidate for clinical trial participation in the opinion of the Investigator.
  • Subject is determined by the investigator to be unsuitable for participation in this trial for any reason.
Terms in these criteria, in plain language(6)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

INR, PT and aPTT (clotting tests)

Blood tests of how long blood takes to clot. The INR is the prothrombin time (PT) put on a common scale; about 1 is usual for someone not taking a blood thinner.

Criteria often make an exception for people on a blood thinner such as warfarin, whose INR is raised on purpose.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

    Eclipse XL1 Coil Treatment Group

    All subjects will be assigned to the XL1 Coil treatment group.

    Device: Distraction Enterogenesis in Adult Patients with Short Bowel Syndrome

Interventions

  • DeviceDistraction Enterogenesis in Adult Patients with Short Bowel Syndrome

    The surgeon verifies the intestinal diameter and selects the appropriate device diameter size. The device is introduced into the lumen of the intestine and advanced about 5-10cm. The surgeon uses 4-0 chromic sutures placed in the seromuscular layer to secure the XL1 Coil within the intestine. The surgeon places metal clips on proximal and distal sutures and in the mesentery adjacent to the XL1 Coil ends to mark the location for radiologic evaluation. The surgeon releases the XL1 Coil and closes the enterotomy.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Sep 2023 (actual). Primary completion is estimated for Mar 2028, 53 months after the start.

Of 24 interventional studies with no phase under Short Bowel Syndrome, half reached primary completion within 22 months of starting (the median), counting those still running; a quarter within 19 and three quarters within 59. This study's planned 53 months is above that.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 12, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
