General

In clinical trials, 2514 patients were treated with this drug. In comparative trials, serious side effects related to infection were reported more often in patients treated with this drug (7%) versus comparators (6%), with sepsis/septic shock reported in 2% and 1% of patients treated with this drug and comparator drugs, respectively. The most common side effects were nausea and vomiting which usually occurred within the first 2 days of therapy and were of mild or moderate severity. This drug was discontinued due to side effects in 7% of patients (compared to 6% for all comparators). Discontinuation was most often due to nausea (1%) and vomiting (1%) inpatients treated with this drug and nausea (less than 1%) in comparator-treated patients.

In all 13 phase 3 and 4 trials that included a comparator, death occurred in 4% and 3% of patients receiving this drug and comparator drugs, respectively. The cause of this imbalance has not been determined. In general, deaths resulted from worsening infection, complications of infection, or underlying comorbidities.^[Ref]
