6.1 Adverse Reactions in Clinical Trials 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.
The data described below reflect exposure to Azacitidine for Injection in 443 MDS patients from 4 clinical studies.
Study 1 was a supportive-care controlled trial (subcutaneous administration), Studies 2 and 3 were single arm studies (one with subcutaneous administration and one with intravenous administration), and Study 4 was an international randomized trial (subcutaneous administration) [ see Clinical Studies (14) ].
In Studies 1, 2 and 3, a total of 268 patients were exposed to Azacitidine for Injection, including 116 exposed for 6 cycles (approximately 6 months) or more and 60 exposed for greater than 12 cycles (approximately one year).
Azacitidine for Injection was studied primarily in supportive-care controlled and uncontrolled trials (n=150 and n=118, respectively).
The population in the subcutaneous studies (n=220) was 23 to 92 years old (mean 66.4 years), 68% male, and 94% white, and had MDS or AML.
The population in the intravenous study (n=48) was 35 to 81 years old (mean 63.1 years), 65% male, and 100% white.
Most patients received average daily doses between 50 and 100 mg/m 2 .
In Study 4, a total of 175 patients with higher-risk MDS (primarily RAEB and RAEB-T subtypes) were exposed to Azacitidine for Injection.
Of these patients, 119 were exposed for 6 or more cycles, and 63 for at least 12 cycles.
The mean age of this population was 68.1 years (ranging from 42 to 83 years), 74% were male, and 99% were white.
Most patients received daily Azacitidine for Injection doses of 75 mg/m 2 .
Table 1 presents adverse reactions occurring in at least 5% of patients treated with Azacitidine for Injection (subcutaneous) in Studies 1 and 2.
It is important to note that duration of exposure was longer for the Azacitidine for Injection-treated group than for the observation group: patients received Azacitidine for Injection for a mean of 11.4 months while mean time in the observation arm was 6.1 months.

Adverse reactions that tended to be more pronounced during the first 1 to 2 cycles of subcutaneous treatment compared with later cycles included thrombocytopenia, neutropenia, anemia, nausea, vomiting, injection site erythema/pain/bruising/reaction, constipation, petechiae, dizziness, anxiety, hypokalemia, and insomnia.
There did not appear to be any adverse reactions that increased in frequency over the course of treatment.
Overall, adverse reactions were qualitatively similar between the intravenous and subcutaneous studies.
Adverse reactions that appeared to be specifically associated with the intravenous route of administration included infusion site reactions (e.g.
erythema or pain) and catheter site reactions (e.g.
infection, erythema, or hemorrhage).
In clinical studies of either subcutaneous or intravenous Azacitidine for Injection, the following serious adverse reactions occurring at a rate of < 5% (and not described in Tables 1 or 2) were reported: Blood and lymphatic system disorders: agranulocytosis, bone marrow failure, pancytopenia splenomegaly.
