Prescribing Information

Protect the central line
with demonstrated safety

Safety comparable with the standard of care (SOC) (heparin)

This was demonstrated across a large and diverse chronic HD-CVC patient population reflective of real-world patients in the US.1,2

In LOCK-IT-1001:

The safety of DefenCath
was evaluated in797 patients(398 DefenCath vs 399 heparin control)

over a mean duration of

173 days(range, 4 to 863 days)

Adverse reactions were similar between DefenCath® (taurolidine and heparin) catheter lock solution and heparin control1

Serious adverse reactions occurred in 40% (159/398) of patients receiving DefenCath as a CLS and 42% (167/399) of patients receiving heparin as a CLS.1 Adverse reactions leading to death occurred in 5% (18/398) patients in the DefenCath arm and 5% (21/399) of patients in the heparin arm.1

Common adverse reactions1:

Adverse reactions were reported in 79% (314/398) of patients using DefenCath and 79% (315/399) of patients using heparin control.

Loss of catheter patency occurred more frequently with DefenCath than heparin (16% vs. 12%, respectively), including higher rates of thrombolytic agent use (12% vs. 8%, respectively).

Discontinuations1:

Adverse reactions leading to discontinuation of study drug occurred in 17% (69/398) of patients in the DefenCath arm and 18% (72/399) of patients in the heparin arm.

Selected adverse reactions occurring in ≥2% of patients receiving DefenCath or
heparin control1

IMPORTANT SAFETY INFORMATION (cont'd)

CONTRAINDICATIONS

DefenCath is contraindicated in patients with:

  • Known heparin-induced thrombocytopenia (HIT).
  • Known hypersensitivity to taurolidine, heparin or the citrate excipient (components of DefenCath), or pork products.

WARNINGS AND PRECAUTIONS

  • Heparin-Induced Thrombocytopenia (HIT): HIT was reported in patients using heparin, a component of DefenCath, as a catheter lock solution. If HIT occurs, discontinue DefenCath and institute appropriate supportive measures.
  • Drug Hypersensitivity: Drug hypersensitivity reactions have been reported in patients using heparin, a component of DefenCath, as a catheter lock solution. If a hypersensitivity reaction occurs, discontinue DefenCath and institute appropriate supportive measures.

ADVERSE REACTIONS

The most frequently reported adverse reactions occurring in ≥2% of patients using DefenCath as a CLS were hemodialysis catheter malfunction, hemorrhage/bleeding, nausea, vomiting, dizziness, musculoskeletal chest pain, and thrombocytopenia.
