LIMITED POPULATION: DEFENCATH is a combination of taurolidine, a thiadiazinane antimicrobial, and heparin, an anti-coagulant, indicated to reduce the incidence of catheter-related bloodstream infections (CRBSI) in adult patients with kidney failure receiving chronic hemodialysis (HD) through a central venous catheter (CVC). This drug is indicated for use in a limited and specific population of patients. ( 1 ) Limitations of Use The safety and effectiveness of DEFENCATH have not been established for use in populations other than adult patients with kidney failure receiving chronic HD through a CVC.

5 WARNINGS AND PRECAUTIONS Heparin-Induced Thrombocytopenia (HIT) : HIT was reported in Trial 1 at an incidence rate of 0.3% in patients using heparin, a component of DEFENCATH as a CLS. If HIT occurs, discontinue DEFENCATH and institute appropriate supportive measures. ( 5.1 ) Drug Hypersensitivity Reactions : Drug hypersensitivity reactions were reported in Trial 1 at an incidence rate of 0.5% in patients using heparin, a component of DEFENCATH, as a CLS. If a hypersensitivity reaction occurs,...

Overview of the Safety Evaluation of DEFENCATH The safety of DEFENCATH was evaluated in a single, active-controlled, double-blind, randomized Phase 3 trial, LOCK-IT-100 (referred to as Trial 1), in adult patients with kidney failure receiving chronic HD through a CVC. In Trial 1, the safety population was comprised of 797 patients with 398 patients using DEFENCATH as a CLS and 399 using heparin as a CLS. Patients used DEFENCATH as a CLS for a mean duration of 173 days, and a range of 4 to 863 days. The mean age of the patients in Trial 1 was 61 years, 58% of patients identified as male (42% patients identified as female), 63% of patients identified as white and 30% identified as black or African-American. Patients with diabetes at baseline accounted for 70% of patients and the mean body mass index (BMI) of patients in the study was 30. The majority of patients (68%) had been receiving HD for 12 months or less. The location of the CVC was the jugular vein in 92% of patients. Serious Adverse Reactions and Adverse Reactions Leading to Discontinuation In Trial 1, 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. Adverse reactions leading to death occurred in 5% (18/398) of patients in the DEFENCATH arm and 5% (21/399) of patients in the heparin arm. 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. Common Adverse Reactions In Trial 1, adverse reactions were reported in 79% (314/398) of patients using DEFENCATH as a CLS and 79% (315/399) of patients using heparin. Table 1 lists selected adverse reactions occurring in โฅ2% of patients using DEFENCATH or heparin in Trial 1.

Overall, a total of 236 patients in the DEFENCATH arm and 225 patients in the heparin arm had a catheter removal for any reason, including loss of catheter patency. 28 (7) 26 (7) Catheter Removal without Thrombolytic Agent Use 17 (4) 15 (4) Other Adverse Reactions Clinically significant adverse reactions that occurred in fewer than 1% of patients receiving DEFENCATH in Trial 1 are listed below: Metabolism and Nutrition Disorders: Hypocalcemia Nervous System Disorders: Dysgeusia 6.2 Postmarketing Experience The following adverse reaction has been identified during the use of a taurolidine and heparin containing CLS outside of the United States. Because this reaction is reported from a population of uncertain size, it is not always possible to reliably estimate its frequency or establish a causal relationship to drug exposure.
