Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of Beleodaq may not reflect the rates observed in practice.

Adverse Reactions In Patients With Peripheral T-Cell Lymphoma

The safety of Beleodaq was evaluated in 129 patients with relapsed or refractory PTCL in the single arm clinical trial in which patients were administered Beleodaq at a dosage of 1,000 mg/m² administered over 30 minutes by IV infusion once daily on Days 1-5 of a 21-day cycle. The median duration of treatment was 2 cycles (range 1 – 33 cycles).

The most common adverse reactions observed in the trial of patients with relapsed or refractory PTCL treated with Beleodaq were nausea, fatigue, pyrexia, anemia, and vomitin. Table 2 summarizes the adverse reactions regardless of causality from the trial in patients with relapsed or refractory PTCL.

Serious Adverse Reactions

Sixty-one patients (47.3%) experienced serious adverse reactions while taking Beleodaq or within 30 days after their last dose of Beleodaq. The most common serious adverse reactions (> 2%) were pneumonia, pyrexia, infection, anemia, increased creatinine, thrombocytopenia, and multi-organ failure.

One treatment-related death associated with hepatic failure was reported in the trial. One patient with baseline hyperuricemia and bulky disease experienced Grade 4 tumor lysis syndrome during the first cycle of treatment and died due to multi-organ failure. A treatment-related death from ventricular fibrillation was reported in another monotherapy clinical trial with Beleodaq. ECG analysis did not identify QTc prolongation.

Discontinuations Due To Adverse Reactions

Twenty-five patients (19.4%) discontinued treatment with Beleodaq due to adverse reactions. The adverse reactions reported most frequently as the reason for discontinuation of treatment included anemia, febrile neutropenia, fatigue, and multi-organ failure.

Dosage Modifications Due To Adverse Reactions

In the trial, dosage adjustments due to adverse reactions occurred in 12% of Beleodaq-treated patients.
