Adverse Reactions
6.1 Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
Bleeding
In 6010 patients undergoing PCI treated in the REPLACE-2 trial, Angiomax patients exhibited statistically significantly lower rates of bleeding, transfusions, and thrombocytopenia as noted in Table 2.

In 4312 patients undergoing PTCA for treatment of unstable angina in 2 randomized, double-blind studies comparing Angiomax to heparin, Angiomax patients exhibited lower rates of major bleeding and lower requirements for blood transfusions. The incidence of major bleeding is presented in Table 3. The incidence of major bleeding was lower in the Angiomax group than in the heparin group.

Serious, non-bleeding adverse events were experienced in 2% of 2161 Angiomax-treated patients and 2% of 2151 heparin-treated patients. The following individual serious non-bleeding adverse events were rare (>0.1% to <1%) and similar in incidence between Angiomax- and heparin-treated patients. These events are listed by body system: Body as a Whole: fever, infection, sepsis; Cardiovascular: hypotension, syncope, vascular anomaly, ventricular fibrillation; Nervous: cerebral ischemia, confusion, facial paralysis; Respiratory: lung edema; Urogenital: kidney failure, oliguria. In the BAT trial, there was no causality assessment for adverse events.
6.2 Immunogenicity/Re-Exposure
In in vitro studies, Angiomax exhibited no platelet aggregation response against sera from patients with a history of HIT/HITTS.
Among 494 subjects who received Angiomax in clinical trials and were tested for antibodies, 2 subjects had treatment-emergent positive bivalirudin antibody tests. Neither subject demonstrated clinical evidence of allergic or anaphylactic reactions and repeat testing was not performed. Nine additional patients who had initial positive tests were negative on repeat testing.
6.3 Postmarketing Experience
Because postmarketing adverse 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.
The following adverse reactions have been identified during postapproval use of Angiomax: fatal bleeding; hypersensitivity and allergic reactions including reports of anaphylaxis; lack of anticoagulant effect; thrombus formation during PCI with and without intracoronary brachytherapy, including reports of fatal outcomes.[1]
