SIDE EFFECTS

Safety information was available for 52 patients with relapsed or refractory APL who participated in clinical trials of TRISENOX (arsenic trioxide injection) . Forty patients in the Phase 2 study received the recommended dose of 0.15 mg/kg of which 28 completed both induction and consolidation treatment cycles. An additional 12 patients with relapsed or refractory APL received doses generally similar to the recommended dose. Most patients experienced some drug-related toxicity, most commonly leukocytosis, gastrointestinal (nausea, vomiting, diarrhea, and abdominal pain), fatigue, edema, hyperglycemia, dyspnea, cough, rash or itching, headaches, and dizziness. These adverse effects have not been observed to be permanent or irreversible nor do they usually require interruption of therapy.

Serious adverse events (SAEs), grade 3 or 4 according to version 2 of the NCI Common Toxicity Criteria, were common. Those SAEs attributed to TRISENOX (arsenic trioxide injection) in the Phase 2 study of 40 patients with refractory or relapsed APL included APL differentiation syndrome (n=3), hyperleukocytosis (n=3), QTc interval ≥ 500 msec (n=16, 1 with torsade de pointes), atrial dysrhythmias (n=2), and hyperglycemia (n=2).

The following table describes the adverse events that were observed in patients between the ages of 5 - 73 years treated for APL with TRISENOX (arsenic trioxide injection) at the recommended dose at a rate of 5% or more. Similar adverse event profiles were seen in the other patient populations who received TRISENOX (arsenic trioxide injection) .

Adverse Events (any grade) Occurring in ≥ 5% of 40 Patients with APL who Received TRISENOX (arsenic trioxide) injection at a dose of 0.15 mg/kg/day

The following additional adverse events were reported as related to TRISENOX (arsenic trioxide injection) treatment in 13 pediatric patients (defined as ages 4 through 20): gastrointestinal (dysphagia, mucosal inflammation/stomatitis, oropharyngeal pain, caecitis), metabolic and nutrition disorders (hyponatremia, hypoalbuminemia, hypophosphatemia, and lipase increased), cardiac failure congestive, respiratory (acute respiratory distress syndrome, lung infiltration, pneumonitis, pulmonary edema, respiratory distress, capillary leak syndrome), neuralgia, and enuresis. Pulmonary edema (n=l) and caecitis (n=l) were considered serious reactions.

Post-Marketing Experience

The following reactions have been reported from clinical trials and/or world-wide post-marketing surveillance. Because they are reported from a population of unknown size, precise estimates of frequency cannot be made.

Cardiac disorders: ventricular extrasystoles in association with QT prolongation, and ventricular tachycardia in association with QT prolongation

Nervous system disorders: peripheral neuropathy

Hematologic disorders: pancytopenia

Respiratory, thoracic, and mediastinal disorders: A differentiation syndrome, like retinoic acid syndrome, has been reported with the use of TRISENOX (arsenic trioxide injection) for the treatment of malignancies other than APL. See BOXED WARNING.

DRUG INTERACTIONS

No formal assessments of pharmacokinetic drug-drug interactions between TRISENOX (arsenic trioxide injection) and other agents have been conducted. Caution is advised when TRISENOX (arsenic trioxide injection) is coadministered with other medications that can prolong the QT interval (e.g., certain antiarrhythmics or thioridazine) or lead to electrolyte abnormalities (such as diuretics or amphotericin B).
