Study summary

The primary objective of this open-label pilot study is to investigate whether an endoscopically placed lumen apposing metal stent is an effective alternative to surgery in patients that have a clear indication for reversal of their gastric bypass.

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

  • Group 1) patients needing any kind of parenteral nutritional support (eg. hypo- albuminemia, hypovitaminoses, mineral deficiencies,...) that can not be corrected by dietary intervention/oral supplementation
  • Group 2) patients with persistent invalidating symptomatic dumping syndrome despite optimal dietary intervention (typical complaints are headache, sweating, trembling, weakness and feeling hungry).
  • Group 3) patients with a marginal ulcers with stenosis of the gastrojejunostomy leading to feading difficulties.
  • Group 4) patients with F3 or F4 liver fibrosis and a tendency to decompensation after bypass surgery, as demonstrated by an increase in serum / and/or lowering of serum albumin.

Exclusion criteria

Exclusion Criteria:

  1. Uncorrectable coagulopathy
  2. Presence of significant portal hypertension as demonstrated by 2.1) the presence of esophageal and/or gastric varices AND/OR 2.2) a hepatic venous pressure gradient (if measured) equal to or more than 10mm Hg AND/OR 2.3) the combination of

    1. a count \<150000/µl AND
    2. liver stiffness measured by elastometry equal to or more than 20 kPa (Baveno guidelines).
  3. Pregnant women, breastfeeding women or women that can not assure adequate anticonception for the duration of the study (based on anamnesis).
  4. index less than 60
  5. Vulnerable patients
Terms in these criteria, in plain language(5)

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.

Relapsed and refractory

Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

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.

Karnofsky performance status (KPS)

A 0–100 scale of how well someone can carry out everyday activities. 100 is no complaints and no signs of illness; 70 is able to look after yourself but not to work or keep up normal activity; 50 is needing considerable help and frequent medical care.

Studies often ask for 60 or 70 and above. Your doctor gives the score.

Study arms

  • Experimental
    LAMS gastro-gastrostomy

    Device: The Hot AXIOS™ Stent and Electrocautery-Enhanced Delivery System

Interventions

  • DeviceThe Hot AXIOS™ Stent and Electrocautery-Enhanced Delivery System

    EUS-guided gastro-gastrostomy using the Hot Axios device: Using a therapeutic endoscopic ultrasound endoscope with a working channel of 3.7mm and under fluoroscopic control, the excluded stomach will be identified and punctured with a 19G needle. Contrast injection will confirm the good position of the needle in the excluded stomach. If needed, the excluded stomach will be filled with blue-stained aqua (5% indigocarmine) until a sufficient distension is obtained for placement of the lumen-apposing metal stent. A lumen-apposing metal stent with a diameter of 20mm will be used according to the manufacterers' instructions to create a gastrogastrostomy. Position will be checked with fluoroscopy.

What researchers measure

Primary outcomes

  1. clinical succes rate

    1. for patients needing parenteral support: the number of parenteral supplements over a 6-month timeframe. 2. for patients with symptomatic hypoglycemia: resolution of hypoglycemia- associated complaints + negative hypoglycemia-provocative testing (oral glucose tolerance test and/or mixed meal test) at 6 months post-intervention. 3. for patients with gastric outlet obstruction: resolution of gastric outlet obstruction- associated symptoms at 6 months post-intervention. 4. for patients with steatohepatitis and signs of liver failure: improvement of liver function (significant drop in bilirubin/INR; increase in serum albumin) at 6 months post-intervention.

    Time frame: 6 months

Secondary outcomes

  1. Technical success rate

    Correct placement of the lumen-apposing metal stent in the desired position, scored yes/no

    Time frame: 12 months

  2. Duration of the procedure

    time interval from scope introduction to successful deployment of the lumen-apposing metal stent.

    Time frame: 12 months

  3. Complication rate

    These include procedure-related complications such as bleeding, perforation, stent migration, peritonitis, reflux disease … Complications will be divided into early (within 24h) and late (after 24h but within 30 days) complications. The severity of each complication will be scored as followed: 1. mild: requiring admission or prolongation of planned admission \<3 days; 2. moderate: requiring prolongation of planned admission to 3-10 days; 3. severe: requiring prolongation of planned admission to more than 10 days or requiring surgery; 4. fatal: leading to death

    Time frame: 12 months

  4. Reintervention rate

    endoscopic and/or surgical, reason should be clearly mentioned: due to loss of stent patency, stent migration, side-effects,…

    Time frame: 12 months

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 Jan 2023 (actual). Primary completion is estimated for Oct 2027, 57 months after the start.

Of 169 non-industry interventional studies with no phase under Hypoglycemia, half reached primary completion within 18 months of starting (the median), counting those still running; a quarter within 8 and three quarters within 33. This study's planned 57 months is above that.

Counting every sponsor, half of 175 studies reached it within 17 months; a quarter within 7 and three quarters within 33.

How these figures are worked out, and which studies are left out of them.

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 Oct 8, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
