Indirect inhibition by heparin requires the presence of AT, the actual inhibitor.
Indirect Versus Direct Thrombin Inhibition
ANGIOMAX® (bivalirudin) inhibits thrombin directly with high affinity and specificity.
ANGIOMAX provides rapid, effective thrombin inhibition to prevent thrombosis and thrombin-mediated platelet effects.
AT=antithrombin.Hirsh J et al. Chest. 2001;119(1 suppl):64S-94S.Weitz JI et al. Thromb Res. 2002;106:V275-V284.

Clot Burden in ACS
• Many ACS patients already have significant clot burden– 94% of patients with UA have angioscopic-evident clot
– Only 13% of clots are identified by angiography
Brummel KE et al. Blood. 2002;100:148-152.White CJ et al. In: Textbook of Interventional Cardiology. 2003:873-891.
T=red, globular mass of thrombus (clot); UA=unstable angina; W=guidewire within the lumen.
• Clot contains activated platelets and active thrombin, which continues to activate and recruit more platelets – 96% of thrombin is still being generated after the clot is visible

Heparin (long strand) binds to other plasma proteins (colored molecules) and platelets, reducing the availability of heparin to bind to AT.
Heparin-binding proteins are elevated in ACS.
Heparin Binds to Plasma Proteins; ANGIOMAX® (bivalirudin) Binds Specifically to Thrombin
ANGIOMAX (bright blue) binds onlyto thrombin (orange).
ANGIOMAX is not neutralized by other plasma proteins or platelets; it remains fully active near thrombus.
ACS=acute coronary syndromes.
Hirsh J et al. Chest. 2001;119(suppl 1):64S-94S.Weitz JI et al. Thromb Res. 2002;106:V275-V284.Wittkowsky AK. Pharmacotherapy. 2002;22(6 Pt 2):97S-104S.
10
Heparin is neutralized by PF4, which is present in high concentrations near vascular injury.
Thrombin continues activating platelets.
PF4/heparin complex antibodies activate platelets, causing thrombocytopenia as well as HIT/TS.
ANGIOMAX® (bivalirudin) does not bind to PF4, and remains fully active.
There is no risk of HIT/TS or other thrombotic events associated with PF4/heparin antibodies.
Consequences of Nonspecific Binding
HIT/TS=heparin-induced thrombocytopenia thrombosis syndrome; PF4=platelet factor 4.Weitz JI et al. Thromb Res. 2002;106:V275-V284.Williams RT et al. Circulation. 2003;107:2307-2312.
11
Heparin Increases Platelet Activation
Heparin makes platelets more reactive to activation by other agonists such as ADP. Heparin binds to the platelet GP IIb/IIIa receptor.
Given the various ways heparin increases platelet activation, its use may actually increase the need for antiplatelet agents.
ADP=adenosine diphosphate.Becker R et al. J Invasive Cardiol. 2003;(suppl):1-15. Sobel M et al. J Vasc Surg. 2001;33:587-594.Xiao Z et al. Circulation. 1998;97:251-256.

Return to Hemostasis—Safety Advantage
ANGIOMAX® (bivalirudin) is cleaved by thrombin, allowing thrombin to quickly recover hemostatic activity upon discontinuation of ANGIOMAX.2
The natural reversibility and the short, 25-minute half-life may explain the significantly lower bleeding rates seen in clinical trials.3
When heparin dissociates from cells/proteins, there can be an anticoagulant effect even when it's not needed. This may explain the prolonged bleeding risk after discontinuation of heparin.1

ANGIOMAX® (bivalirudin)—Unique Mechanism of Action Overcomes the Limitations of Heparin
• Direct thrombin inhibitor that is reversible via thrombin yielding a 25-minute half-life– Heparin requires antithrombin to be able to deactivate thrombin
• Inhibits clot-bound and circulating thrombin– Heparin fails to effectively inhibit clot-bound thrombin
• Inhibits thrombin-mediated platelet aggregation and does not activate platelets– Heparin activates platelets
• Provides predictable pharmacology and linear pharmacokinetics– Heparin is unpredictable and has nonlinear pharmacokinetics
18
SYNERGY: Switching Between Heparins
• SYNERGY overall primary end point results– No difference in the composite of death/MI with enoxaparin
compared with UFH
– Significant increase in bleeding (TIMI major) with enoxaparin compared with UFH
• Patients who crossed over after randomization from UFH to enoxaparin or vice versa had– Increased rates of death/MI at 30 days compared with those who
did not cross over
– More bleeding complications (transfusions)

MI=myocardial infarction; TIMI=Thrombosis in Myocardial Infarction.

SYNERGY: Switching Between Heparins
• The SYNERGY trial suggested that changing therapies between UFH and enoxaparin (or vice versa) resulted in an increased risk of bleeding
• Do these findings apply to ANGIOMAX® (bivalirudin)? Is it better to switch to ANGIOMAX or stay on consistent heparin therapy?
22
Evidence to Support Switching to ANGIOMAX® (bivalirudin)• BAT analysis (Bittl)
– Evaluate switching in era of conservative management
– Switching to ANGIOMAX improved ischemic and bleeding outcomes
– Improvements more profound in higher risk strata
• SWITCH study (Waksman)– Impact (safety) of switching, relative to last enoxaparin dose
– Switching outcomes consistent with other ANGIOMAX trials
• REPLACE-2 analysis (Gibson)– Data in patients undergoing PCI
– Switching to ANGIOMAX associated with improved bleeding outcomes
• ACUITY analysis (White)– Data in ACS patients undergoing PCI
– Switching to ANGIOMAX yielded improved bleeding outcomes

Additional ConsiderationsANGIOMAX® (bivalirudin) Important Safety Information, Dosing and Administration
53
Important Safety Information
• ANGIOMAX® (bivalirudin) with provisional use of GP IIb/IIIa inhibitor is indicated for use as an anticoagulant in patients undergoing percutaneous coronary intervention (PCI), and in patients with or at risk for heparin-induced thrombocytopenia and thrombosis syndrome (HIT/HITTS) undergoing PCI
• ANGIOMAX is intended for use with aspirin and has been studied only in patients receiving concomitant aspirin
• ANGIOMAX is contraindicated in patients with active major bleeding or hypersensitivity to ANGIOMAX or its components
• The most common (≥10%) adverse events for ANGIOMAX were back pain, pain, nausea, headache, and hypotension
• An unexplained fall in blood pressure or hematocrit, or any unexplained symptom, should lead to serious consideration of a hemorrhagic event and cessation of ANGIOMAX administration
ANGIOMAX (bivalirudin) [prescribing information]; December 6, 2005.
54
Dosing and Administration
• The recommended dose for ANGIOMAX® (bivalirudin) is an intravenous (IV) bolus of 0.75 mg/kg
• This should be followed by an infusion of 1.75 mg/kg/hour for the duration of the PCI procedure or up to 4 hours per physician discretion
• After the 4 hours of the initial infusion, an additional infusion may be initiated at a rate of 0.2 mg/kg/hour for up to 20 hours, if needed
• If the low-rate infusion is used after the initial infusion, a lower concentration bag of 0.5 mg/mL should be prepared. See Prescribing information for diluting instructions
• Special precaution: It is important to note that the pre-PCI ANGIOMAX dose for patients with acute coronary syndromes in the ACUITY trial is not an approved dose and is much lower than the approved PCI dose discussed in these instructions
ANGIOMAX (bivalirudin) [prescribing information]; December 6, 2005.
55
Special Population: Patients With Renal Impairment• No reduction in the bolus dose of ANGIOMAX® (bivalirudin) is needed
• The infusion dose may need to be reduced– Severe renal impairment (CrCl <30 mL/minute): reduction in the infusion rate
to 1.0 mg/kg/hour should be considered
– On hemodialysis: infusion should be reduced to 0.25 mg/kg/hour
• Standard infusion dose for patients with normal to moderate renal impairment (CrCl ≥30 mL/minute)
• Anticoagulation status should be monitored in patients with renal impairment
ANGIOMAX (bivalirudin) [prescribing information]; December 6, 2005.
56
ANGIOMAX® (bivalirudin) in PCI
• ANGIOMAX improves bleeding outcomes while preserving ischemic suppression for UA/NSTEMI patients undergoing PCI even if the patients are switched from UFH or enoxaparin to ANGIOMAX
• Consistent results in low-, moderate-, and high-risk patients
