Understanding how apixaban is processed in patients with short bowel syndrome on long-term nutrition

Pharmacokinetics of Apixaban in Patients With Short Bowel Syndrome Requiring Long Term Parenteral Nutrition

Phase 4 Interventional Universitaire Ziekenhuizen KU Leuven · NCT04344717

This study is trying to see how well the blood thinner apixaban works in adults with short bowel syndrome who need long-term nutrition through an IV.

What this trial studies

This study investigates the pharmacokinetics of apixaban, an anticoagulant, in adult patients suffering from short bowel syndrome (SBS) who require long-term parenteral nutrition. It aims to determine how SBS affects the absorption and effectiveness of apixaban, which is crucial for managing anticoagulation in these patients. The study includes both single-dose and steady-state assessments of apixaban in patients with SBS and healthy controls. By comparing these groups, the research seeks to clarify the drug's behavior in a malabsorptive condition.

Who should consider this trial

Good fit: Ideal candidates include adults with short bowel syndrome on long-term parenteral nutrition who are naive to apixaban and other anticoagulants.

Not a fit: Patients under 18 years old or those who are not Dutch speaking may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved anticoagulation management for patients with short bowel syndrome.

How similar studies have performed: While studies on pharmacokinetics in similar conditions exist, this specific investigation into apixaban in SBS is novel and untested.

Inclusion criteria non-SBS single dose:

- healthy individuals without history of GI resections or other conditions associated with impaired absorption, who are apixaban- and vitamin K antagonist naive

Inclusion criteria non-SBS steady-state:

- patients without history of gastrointestinal resections or other conditions associated with impaired absorption (= controls), who are already taking apixaban 2,5 mg or 5 mg twice daily for ≥ 4 days
