The total safety data base is composed of 921 patients treated with ABELCET® (5 patients were enrolled twice and counted as separate patients), of whom 775 were treated with 5 mg/kg/day. Of these 775 patients, 194 patients were treated in four comparative studies; 25 were treated in open-label, non-comparative studies; and 556 patients were treated in an open-label, emergency-use program. Most had underlying hematologic neoplasms, and many were receiving multiple concomitant medications. Of the 556 patients treated with ABELCET®, 9% discontinued treatment due to adverse events regardless of presumed relationship to study drug.

In general, the adverse events most commonly reported with ABELCET® were transient chills and/or fever during infusion of the drug.

The following adverse events have also been reported in patients using ABELCET® in open-label, uncontrolled clinical studies. The causal association between these adverse events and ABELCET® is uncertain.
