A Study of Tenecteplase for Restoration of Function in Dysfunctional Central Venous Access Catheters - Full Text View

Sponsor:	Genentech
Information provided by:	Genentech
ClinicalTrials.gov Identifier:	NCT00395876

Purpose

This is a Phase III, randomized, double-blind, placebo-controlled study that will be conducted at approximately 25 centers in the United States and Canada. Approximately 100 adult and pediatric subjects with dysfunctional CVA catheters will be randomly assigned in a 1:1 ratio to receive an initial dose of either placebo (Arm A) or tenecteplase (Arm B).

Criteria

Inclusion Criteria:

Clinically stable, in the opinion of the investigator
CVA catheter occlusion
Able to have fluids infused at the volume necessary to instill study drug into the CVA catheter

Exclusion Criteria:

Able to have 3 mL of blood (subjects weighing ≥ 10 kg) or 1 mL of blood (subjects weighing < 10 kg) withdrawn from the selected study CVA catheter following subject repositioning
Selected study CVA catheter inserted < 2 days prior to treatment
Selected study CVA catheter known to be dysfunctional for > 7 days
Selected study CVA catheter implanted specifically for HD
Use of a power injector on the selected study CVA catheter during the study
Evidence of mechanical, non-thrombotic occlusion of the selected study CVA catheter (e.g., kink in the catheter or suture constricting the catheter)
Previously treated in this study or any tenecteplase catheter clearance trial
Use of any investigational drug or therapy within 28 days prior to treatment
Use of a fibrinolytic agent (e.g., alteplase, tenecteplase, reteplase, or urokinase) within 24 hours prior to treatment
Known to be pregnant or breastfeeding at screening
CVA catheter with known or suspected infection
History of any intracranial hemorrhage, aneurysm, or arteriovenous malformation
Use of heparin (unfractionated or low molecular weight) within 24 hours prior to treatment, except for use of intermittent or low-dose, continuous infusion of heparin to maintain catheter or vessel patency
Use of warfarin within 7 days prior to treatment, except for low-dose warfarin used for prophylaxis
Initiation of or increase in dose of Plavix(R) (clopidogrel bisulfate) within 7 days prior to treatment
At high risk for bleeding events or embolic complications (i.e., recent pulmonary embolus, deep vein thrombosis, endarterectomy, or clinically significant right-to-left shunt) in the opinion of the investigator, or with known condition for which bleeding constitutes a significant hazard
Known hypersensitivity to tenecteplase or any component of the formulation
