6 ADVERSE REACTIONS
The most clinically significant adverse reactions are anaphylaxis, infection, thrombocytopenia, leukopenia, arthralgia, edema, bradycardia, and abnormal renal and liver function tests.
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 clinical practice.
The safety of ATGAM has been evaluated in 367 patients with renal transplant and 109 patients with aplastic anemia.
The renal transplantation and aplastic anemia patients received a similar dosing regimen, and these data were pooled to obtain the frequencies listed in Tables 1 and 2 below.
The most commonly reported adverse reactions (occurring in greater than 10% of patients) are pyrexia, chills, rash, thrombocytopenia, leukopenia and arthralgia.
|(N = 476)|
|Abdominal pain upper||2.7|
|Infusion site pain||2.1|
|Arteriovenous fistula thrombosis||1.3|
|Liver function test abnormal||1.0|
|(N = 476)|
|Renal function test abnormal||0.6|
|Renal artery thrombosis||0.2|
|Iliac vein occlusion||0.2|
|Toxic epidermal necrolysis||0.2|
6.2 Post-Marketing Experience
The following adverse reactions have been identified during post approval use of ATGAM. Because 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.
