6 Adverse Reactions

Newly added subsection:

6.2 Postmarketing Experience

The following adverse reactions have been identified during post approval use of argatroban. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

  •  Anaphylaxis

The following adverse reaction is also discussed in other sections of the labeling.

  • Risk of Hemorrhage

Reaction(s) has replaced event(s) throughout section.

8 Use in Specific Populations

8.1 Pregnancy

PLLR conversion; please refer to label for complete information.

8.2 Lactation

Risk Summary

PLLR conversion; additions and/or revisions underlined:

There are not data on the presence of argatroban in human milk, or its effects on mild production. Argatroban is present in rat milk. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Argatroban and any potential adverse effects on the breastfed infant from Argatroban or from the underlying maternal condition.

8.4 Pediatric Use

Additions and/or revisions underlined:

… Major bleeding occurred among two patients; one patient experienced an intracranial hemorrhage after 4 days of argatroban therapy in the setting of sepsis and thrombocytopenia and another patient experienced an intracranial hemorrhage after receiving argatroban for greater than 14 days. The study findings did not establish the safe and effective use of argatroban in pediatric patients and the dosing of 1 mcg/kg/min was not supported by the pharmacokinetic data described below.

Pediatric Pharmacokinetics (PK) and Pharmacodynamics (PD)

PK parameters of argatroban were characterized in population PK/PD analysis model with sparse data from 5 seriously ill pediatric patients. Argatroban clearance in these seriously ill pediatric patients (0.16 L/hr/kg) was 50% lower compared to argatroban clearance in healthy adults (0.31 L/hr/kg).

These PK/PD analysis models based on a goal of aPTT prolongation of 1.5 to 3 times the baseline value and avoidance of an aPTT greater than 100 seconds for seriously ill pediatric patients with HIT/HITTS who require an alternative to heparin suggested the following:

  • For patients with normal hepatic function, a starting infusion rate of 0.75 mcg/kg/min may have comparable aPTT responses as a starting dose of 2 mcg/kg/min in healthy adults. Additionally, based on an evaluation of aPTT every two hours, increasing the dosage by 0.1 to 0.25 mcg/kg/min could achieve additional aPTT responses.

  • For patients with hepatic impairment a starting infusion rate of 0.2 mcg/kg/min with increasing dosing by increments of 0.05 mcg/kg/min may have comparable argatroban exposure as expected with adult doses.

The safety and effectiveness of argatroban with the above dosing have not been adequately assessed in pediatric patients and the safety and effectiveness of argatroban is not established in pediatric patients. In addition, the described dosage did not take into account multiple factors that could affect the dosage such as current aPTT, target aPTT, and the clinical status of the patient.
