Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 100
Healthy volunteers: no

Brief summary:
This was a Phase III, randomized, double-blind, placebo-controlled study that was conducted at 24 centers in the United States and Canada. 100 adult and pediatric patients with dysfunctional central venous catheters (CVCs) were randomly assigned in a 1:1 ratio to receive an initial dose of either placebo (Arm A) or tenecteplase (Arm B).

Detailed description:

Arms:
arm 1: None arm 2: None

Interventions: intervention 1: placebo intervention 2: tenecteplase
Intervention descriptions: intervention 1: 2 mL of placebo instilled into lumen of dysfunctional CVC. Patients weighing ≥ 30 kg received 2-mL instillations of study drug (i.e., 2 mg of placebo). Patients weighing \< 30 kg received instillations of study drug equal to 110% of the internal lumen volume of the dysfunctional CVC. This dose was rounded to the nearest 0.1 mL and should not have exceeded 2 mL (2 mg). intervention 2: 2 mL of reconstituted lyophilized tenecteplase instilled into lumen of dysfunctional CVC. Patients weighing ≥ 30 kg received 2-mL instillations of study drug (i.e., 2 mg of tenecteplase). Patients weighing \< 30 kg received instillations of study drug equal to 110% of the internal lumen volume of the dysfunctional CVC. This dose was rounded to the nearest 0.1 mL and should not have exceeded 2 mL (2 mg).
