Primary Outcome Measures:
  • Restoration of central access device patency following one, two or three instillations of t-PA. [ Time Frame: within 180 minutes of administering the study drug ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Restoration of patency following instillation of 1 mg/mL (i.e., first instillation) [ Time Frame: within 60 minutes from the first instillation of study drug ] [ Designated as safety issue: No ]
  • Restoration of patency following instillation of 1 mg/mL (i.e., second instillation) [ Time Frame: within 60 minutes from the second instillation of study drug ] [ Designated as safety issue: No ]
  • Restoration of patency following instillation of 2 mg/mL (i.e., third instillation) [ Time Frame: within 60 minutes from the third instillation of study drug ] [ Designated as safety issue: No ]
  • The following safety outcome measure will be evaluated: • Major bleeding complications • Sepsis • Embolic events • All serious adverse events [ Time Frame: Within 14 days of study drug administration ] [ Designated as safety issue: Yes ]

  Eligibility

Ages Eligible for Study:   28 Weeks to 66 Weeks
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Ability to provide written informed consent by the parent or legal guardian and comply with study assessments for the full duration of the study
  • Hospitalized premature neonates (28- < 34 weeks CGA), term neonates (34 weeks-< 40 weeks CGA) and infants (> = 40 weeks to 6 months CGA).
  • Presence of central access device. All types of permanent and temporary catheters are eligible [e.g., central venous catheter (CVC), peripherally-inserted central catheter (PICC), umbilical arterial catheter (UAC), or umbilical venous catheter (UVC)] except hemodialysis catheters. The catheter must be properly inserted as evidenced by the ability to have used the catheter at least once for its intended purpose (i.e., to withdraw blood and/or infuse fluids)and documentation correct catheter placement radiographically within 48 hours of the catheter becoming non-patent.
  • Partial or total occlusion of at least one lumen of the catheter

Exclusion Criteria:

  • CGA > 66 weeks
  • Incorrect catheter placement or evidence of mechanical occlusion
  • Occlusion due to suspected drug precipitate
  • Active internal bleeding, involving intracranial or retroperitoneal sites, or the gastrointestinal, genitourinary, or respiratory tracts
  • Recent history (i.e., < 6 months) of intraventricular hemorrhage (IVH) or other active intracranial process that could predispose to intracranial bleeding
  • Superficial or surface bleeding, observed mainly at vascular puncture and access sites (e.g., venous cutdowns, arterial punctures) or site of recent surgical intervention
  • Any of the following known or suspected hemorrhagic events within the preceding 7 days or any other significant bleeding risk:

    • Gastrointestinal bleeding
    • Intra-ocular surgery
  • Any of the following known events or suspected hemorrhagic events within the preceding 48 hours

    • Major surgery (excluding central line placement)
    • Organ biopsy
    • Major trauma
  • Puncture of a non-compressible vessel within the previous 48 hours
  • Treatment with indomethacin within the previous 48 hours
  • Received any fibrinolytic agent within 24 hours of enrollment
  • Known risk for embolization, including history of left heart thrombus, mitral mitral stenosis with atrial fibrillation, acute pericarditis, and subacute bacterial endocarditis
  • Known hypersensitivity to alteplase or any component in the formulation of CathfloTM Activase®
  • Prior enrollment in the current study
  • Any other condition that the investigator believes would pose a significant hazard to the subject if the investigational therapy were initiated or the patient has a known condition for which bleeding constitutes a significant hazard
  • Participation in another simultaneous interventional medical investigation or trial
  • Documented or suspected catheter infection
  • Thrombocytopenia (i.e. platelet count < 20,000)
