Improvement 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.

Darbepoetin alfa administration to achieve and maintain target hemoglobin levels for 1 year in patients with chronic kidney disease.

Objective: To assess the efficacy and safety of every-other-week darbepoetin alfa therapy in treating anemia and maintaining hemoglobin levels for 1 year in patients with chronic kidney disease (CKD) who were not undergoing dialysis and who had not previously received erythropolesis-stimulating proteins (ESPs).

Patients And Methods: This multicenter 52-week study (evaluation period, weeks 20-32), a subanalysis of the Simplify the Treatment of Anemia with Aranesp study, enrolled patients with CKD who were not receiving dialysis (creatinine clearance < or =70 mL/min or estimated glomerular filtration rate [GFR] < or =60 mL/min). Patients evaluated in this analysis were not receiving ESPs, had hemoglobin concentrations less than 11 g/dL, and had transferrin saturation of 20% or higher during screening.
