Brief Summary:
The purpose of this study is determine safety and effectiveness of Neutrolin, a catheter lock solution, for prevention of central venous catheter associated bloodstream infection in hemodialysis patients.

Condition or disease Intervention/treatment Phase
Kidney Failure, Chronic Catheter-Related Infections Drug: Neutrolin Drug: Heparin Phase 3

Detailed Description:

The objective of this study is to demonstrate the efficacy and safety of Neutrolin® as a catheter lock solution (CLS) on prevention of catheter-related bloodstream infection (CRBSI), and the incidence of treatment-emergent adverse events in subjects receiving hemodialysis (HD) for the treatment of End Stage Renal Disease (ESRD) when compared with heparin 4,000 USP Units/4mL (1,000 USP Units/mL).

This is a randomized, double-blind, active control, parallel-arm, multicenter study. Six hundred and thirty two subjects will be randomized in a 1:1 ratio to receive either Neutrolin® or the active control heparin (Heparin sodium USP 1,000 units/mL, Benzyl alcohol 9.45 mg/mL and Sodium chloride 9.0 mg/mL) as a CLS.

Approximately 632 randomized subjects are planned for this trial. In this study, one-half of the subjects (316 subjects) will receive Neutrolin as a study drug and the other half will receive heparin 4,000 USP Units/4mL (1,000 USP Units/mL) with benzyl alcohol preservative as a comparator. Subjects will be assigned in a 1:1 ratio using permuted blocks without additional stratification for both groups.

The primary objective of this study is to demonstrate the effectiveness of Neutrolin® as a CLS in ESRD subjects undergoing HD treatment using a permanent, cuffed, tunneled silicone or polyurethane HD catheter. The study will evaluate whether Neutrolin® is superior to the active control heparin by documenting the time to CRBSI and consequently delaying the time until the occurrence of CRBSI.

Arm Intervention/treatment
Experimental: Neutrolin arm
Neutrolin: Neutrolin will be added to the central venous catheter after dialysis as a lock solution
Drug: Neutrolin
Neutrolin® will be instilled into central venous HD catheters at the discontinuation of all dialysis sessions and will be withdrawn prior to the initiation of the next dialysis session
Other Name: 1.35% taurolidine, 3.5% citrate, heparin 1,000 USP Units/mL

Active Comparator: Heparin arm
Heparin: Heparin will be added to the central venous catheter after dialysis as a lock solution
Drug: Heparin
Heparin will be instilled into central venous HD catheters at the discontinuation of all dialysis sessions and will be withdrawn prior to the initiation of the next dialysis session
Other Name: Heparin Sodium

Primary Outcome Measures :
  1. Occurrence of catheter related bloodstream infection [ Time Frame: 18 months (data will be collected at the time event occurs) ]

Secondary Outcome Measures :
  1. Catheter Patency: Loss of catheter patency following enrollment in the study. Catheter Removal: Catheter removal for any reason. [ Time Frame: 18 months ]
    Loss of catheter patency is defined as required use of a tissue plasminogen activating factor (tPA) or removal of catheter due to dysfunction.

Other Outcome Measures:
  1. Biofilm Analysis: The analysis will aim to determine if endoluminal bacterial colonization is present, identify the species and quantify the thickness of the biofilm. [ Time Frame: 18 months ]

Inclusion Criteria:

  1. Subject has ESRD and undergoes chronic HD at least two times per week
  2. Subject has a HD catheter that has demonstrated the ability to achieve a minimum blood flow of at least 250 mL/min for at least two consecutive dialysis sessions blood flow to enable successful HD
  3. The HD catheter is implanted with the tip in a jugular or subclavian vein
  4. The subject is not expected to expire within 180 days

  6. The subject (or the legal guardian) understands the nature of the study and provides written informed consent prior to the study enrollment
  7. The subject is willing to comply with specified follow-up evaluations and prescribed dialysis therapy and
  8. If female and of childbearing potential, the subject must have a negative pregnancy test at the screening visit (i.e., subject is not pregnant); not be lactating; and use an acceptable method of contraception, including abstinence, a barrier method (diaphragm or condom), Depo-Provera, or hormonal contraceptive (oral, implant, ring, patch) for the duration of the study. (NOTE: The subject must have used the chosen method of birth control for at least 1 month/cycle prior to enrollment into the study).

Exclusion Criteria:

  5. Subjects using any type of antimicrobial-coated or heparin-coated catheter
  6. Documented chronic bleeding diathesis, active or recurrent bleeding within 1 month prior to randomization
  7. Documented history of an atrial thrombus or known hypercoagulable state
  8. Subjects with open, non-healing skin ulcers
