New catheter lock may cut blockages in kids on long-term nutrition
NCT ID NCT05879835
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests if a 4% tetrasodium EDTA solution is better than the standard heparin lock at preventing central line blockages in children with intestinal failure who need long-term nutrition through a vein. About 124 children from multiple hospitals will take part. The goal is to reduce the need for extra procedures to fix blocked catheters and to see if it also lowers infection rates.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Patients managed by the intestinal rehabilitation program at one of the participating centers. 2. Diagnosis of intestinal failure defined as need for PN support for \>60 days in previous 74 days for primary intestinal disease (short bowel syndrome, primary motility disorder, mucosal enteropathy). 3. Expectation of the treating physician that the patient will require PN for at least 6 months following enrollment. 4. Age less than 18 years at diagnosis but greater than 4 weeks chronological age or 40 weeks estimated gestational age, whichever is greater. 5. Stable TPN cycling (4 hours off TPN minimum per day) enabling home TPN management 6. Presence of a tunneled central venous catheter (CVC), port-a-catheter, or peripherally inserted central catheter (PICC). 7. Clinical stability for at least 4 weeks and no acute medical comorbidities. 8. A minimum dwell time of 4 consecutive hours daily. 9. Care provider willing to provide informed consent to participate in the trial and willing to comply with randomization and study protocol. Exclusion Criteria: 1. A temporary CVC (jugular or femoral) or peripheral catheter. 2. Patients receiving long-term PN, but not due to a primary intestinal disorder (i.e., oncology patients or premature neonates on PN due to intestinal immaturity). 3. Known hypersensitivity, allergy, or reaction to EDTA. 4. Pregnancy or nursing mother. 5. Participation in another investigational device or drug trial within 30 days prior to enrollment (unless approved by the principal investigators of the trial). 6. Severe coagulopathy (platelets \<50,000, or INR \> 1.5). 7. Diagnosis of immunodeficiency disorder. 8. Unstable medical condition requiring hospital admission 9. Received antibiotic therapy for CLABSI within last 14 days.
