Condition(s) targeted: Dysfunctional Central Venous Access Devices (CVADS)

Intervention: Cathflo Activase (Alteplase) (Drug)

Phase: Phase 4

Status: Completed

Sponsored by: Genentech, Inc.

Official(s) and/or principal investigator(s):
Martha Blaney, PharmD, Study Director, Affiliation: Genentech, Inc.


This was a Phase IV, open-label, single-arm, multicenter trial that was to be conducted at ~60 sites in the United States. Approximately 300 pediatric subjects with dysfunctional CVADs (including catheters with valves, multiple lumens, umbilical catheters, and implanted ports) were to be treated with up to two serially instilled doses of Cathflo Activase.

Clinical Details

Official title: Cathflo Activase (Alteplase) Pediatric Study (CAPS)

Study design: Primary Purpose: Treatment

Primary outcome: To evaluate the safety, as measured by the incidence of intracranial hemorrhage during the treatment with Cathflo Activase, in restoring function to dysfunctional CVADs in pediatric populations.

Secondary outcome: To estimate the rate of restoration of function to dysfunctional CVADs following administration of up to two instillations of Cathflo Activase.


Minimum age: N/A. Maximum age: 17 Years. Gender(s): Both.


Inclusion Criteria: Subjects had to meet the following inclusion criteria to be eligible for study entry:

- Less than 17 years of age

- For subjects who weighed < 10 kg, inability to withdraw 1 mL of blood from the CVAD

- Selected study catheter implanted specifically for hemodialysis

- Evidence of mechanical, non-thrombotic occlusion of the CVAD (e. g., kink in the CVAD

or suture constricting the catheter)

- Previous enrollment in this study

- Use of fibrinolytic agent (e. g., alteplase, reteplase, tenecteplase, urokinase,

streptokinase) within 24 hours of enrollment

- At high risk for bleeding events, embolic complications (i. e., recent pulmonary

embolism, deep vein thrombosis, endarterectomy, clinically significant right-to-left shunt) in the opinion of the investigator, or with known condition for which bleeding constituted a significant hazard

- Known hypersensitivity to alteplase or any component of the formulation
