Short Gut SyndromePhase 2NCT04604275
Functional Sucrase Deficiency in Short Bowel Syndrome Patients With Intestinal Failure
A Phase 2 study testing Sucrase in people with Short Gut Syndrome, run by University of Miami at 2 sites in United States.
Trial summary
Short gut syndrome with intestinal failure patients may have decreased production of disaccharidases, like sucrase, an enzyme responsible for digesting sugar in foods. This can happen due to loss of bowel length from surgery or from loss of cellular function in the intestines due to use of parenteral nutrition… Read more about this study

About this study
Short gut syndrome with intestinal failure patients may have decreased production of disaccharidases, like sucrase, an enzyme responsible for digesting sugar in foods. This can happen due to loss of bowel length from surgery or from loss of cellular function in the intestines due to use of parenteral nutrition intravenously. Therefore, patients with these conditions may not be able to digest sucrose (sugar) fully. Patients might experience abdominal distension/pain, vomiting and diarrhea when sugar is taken in orally or through the g-tube, which can limit patients' ability to increase oral or g-tube feeds in short gut syndrome patients with intestinal failure.
In patients with short gut syndrome and intestinal failure, the administration of exogenous sucrase (enzyme) may improve sucrose (sugar) digestion and thus the ability to tolerate more oral or g-tube feeds.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
SucraseDrug
1 mL (8,500 I.U.) (one full measuring scoop or 28 drops) per meal or snack for patients up to 15 kg in body weight. 2 mL (17,000 I.U.) for patients over 15kg in body weight. Dosage is 1 or 2 mL (8,500 to 17,000 I.U.) taken orally or by g-tube with each meal or snack diluted in water, milk, or infant formula.
PlaceboOther
1 mL of placebo per meal or snack for patients up to 15 kg in body weight. 2 mL of placebo per meal of snack for patients above 15kg in body weight. Dosage is 1 or 2 mL of placebo taken orally or by g-tube with each meal or snack diluted in water, milk, or infant formula.
| Study group | Role | What they receive |
|---|---|---|
| Sucrase intervention followed by placebo | Experimental | Participants in this arm will receive sucrase for 4 weeks followed by wash out of 1 week with no drug administered then 4 weeks of placebo. Receives: Drug: Sucrase; Other: Placebo |
| Placebo followed by sucrase intervention | Experimental | Participants in this arm will receive placebo for 4 weeks followed by wash out of 1 week with no drug administered then 4 weeks of sucrase. Receives: Drug: Sucrase; Other: Placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Carbohydrate Malabsorption
Degree of carbohydrate malabsorption will be assessed by decrease in number of stools per day.
Measured: baseline, 9 weeks
Change in Carbohydrate Malabsorption as Measured by Patient Symptom Survey
Degree of carbohydrate malabsorption will be assessed by change in patient symptomatology by change in score on patient symptom survey.
The survey has range from 0-52 with higher score being worse symptoms and lower being better.
Measured: baseline, 9 weeks
Change in Carbohydrate Malabsorption as Measured by Growth Velocity
Carbohydrate malabsorption will be measured by increase in growth velocity in kg/week
Measured: baseline, 9 weeks
Change in Carbohydrate Malabsorption as Measured by Enteral Nutrition Tolerance
Carbohydrate malabsorption will be measured by ability to advance enteral nutrition in ml/day
Measured: baseline, 9 weeks
Secondary outcomes (3)
Change in Digestion
Change in digestion will be measured by change in abdominal distension/girth measured in cm
Measured: baseline, 9 weeks
Change in Digestion as Measured by Amount of Emesis
Change in digestion will be assessed by number of emesis per day
Measured: baseline, 9 weeks
Change in Digestion as Measured by Stool Consistency
Change in digestion will be assessed as a change in stool consistency from liquid (7) to solid(1) using Bristol stool chart
Measured: baseline, 9 weeks

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Short gut syndrome with intestinal failure patients may have decreased production of disaccharidases, like sucrase, an enzyme responsible for digesting sugar in foods. This can happen due to loss of bowel length from surgery or from loss of cellular function in the intestines due to use of parenteral nutrition intravenously. Therefore, patients with these conditions may not be able to digest sucrose (sugar) fully. Patients might experience abdominal distension/pain, vomiting and diarrhea when sugar is taken in orally or through the g-tube, which can limit patients' ability to increase oral or g-tube feeds in short gut syndrome patients with intestinal failure.
In patients with short gut syndrome and intestinal failure, the administration of exogenous sucrase (enzyme) may improve sucrose (sugar) digestion and thus the ability to tolerate more oral or g-tube feeds.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Sucrase in people with Short Gut Syndrome, run by University of Miami at 2 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 1 Oct 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 1 Oct 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in Carbohydrate Malabsorption (time frame: baseline, 9 weeks). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Oct 2025.
