Multicenter StudyImprovement of hemodialysis catheter function with tenecteplase: a phase III, open-label study: TROPICS 4.
Hemodialysis (HD) catheters are prone to thrombotic occlusion. We evaluated tenecteplase, a thrombolytic, for the treatment of dysfunctional HD catheters. Patients with tunneled HD catheters and blood flow rate (BFR) <300 mL/min received open-label tenecteplase (2 mg/lumen) for a 1 h intracatheter dwell. ⋯ Reported targeted adverse events included five catheter-related bloodstream infections and one thrombosis. No intracranial hemorrhage, major bleeding, embolic events, or catheter-related complications were reported. Tenecteplase administered as a 1 h or 1 h plus extended dwell was associated with improved HD catheter function in the TROPICS 4 trial.
