Adverse Reactions

In the Phase II and III clinical studies, desirudin was administered to 2159 patients undergoing electivehip replacement surgery to determine the safety and efficacy of Iprivask in preventing VTE in this population. Below is the safety profile of the Iprivask 15 mg (q12h) regimen from these 5 multicenter clinical trials.

Hemorrhagic Events

The following rates of hemorrhagic events have been reported during clinical trials.

^a Includes hematomas which occurred at an incidence of 6% in the Iprivask and enoxaparin treatment groups and 5% in the heparin treatment group. ^b Bleeding complications were considered serious if perioperative transfusion requirements exceeded 5 units of whole blood or packed red cells, or if total transfusion requirements up to postoperative Day 6 inclusive exceeded 7 units of whole blood or packed red cells, or total blood loss up to postoperative Day 6 inclusive exceeded 3500 mL. _c Bleeding complications were considered major if the hemorrhage was: (1) overt and it produced a fall in hemoglobin of ≥2g/dL or if it lead to a transfusion of 2 or more units of whole or packed cells outside the perioperative period (the time from start of surgery until up to 12 hours after); (2) Retroperitoneal, intracranial, intraocular, intraspinal, or occurred in a major prosthetic joint.

Non-hemorrhagic Events

Non-hemorrhagic adverse events occurring at ≥2% incidence in patients treated with Iprivask 15 mg (q 12h) during electivehip replacement surgery and considered to be remotely, possibly, or probably related to desirudin are provided below. ==

^a Represents events reported while on treatment, excluding unrelated adverse events ^b All hemorrhages that occurred are included in ADVERSE REACTIONS, Hemorrhagic Events.

Related Adverse Events with a Frequency of <2% and >0.2% (in decreasing order of frequency): thrombosis, hypotension, leg edema, fever, decreased hemoglobin, hematuria, dizziness, epistaxis, vomiting, impaired healing, cerebrovascular disorder, leg pain, hematemesis.

Allergic Reactions. In clinical studies, allergic events were reported <2% overall and in 2% of patients who were administered 15 mg desirudin. (See PRECAUTIONS, General,Antibodies/ Re-exposure).

Post Marketing

In addition to adverse events reported from clinical trials the following adverse events have been identified during post approval use of Iprivask. These events were reported voluntarily from a population of unknown size and the frequency of occurrence cannot be determined precisely: rare reports of major hemorrhages, some of which were fatal, and anaphylactic/anaphylactoid reactions.
