Black Box Warning
WARNING: NEUROLOGIC ADVERSE REACTIONS
See full prescribing information for complete Boxed Warning.
Neurologic Adverse Reactions
Severe neurologic adverse reactions have been reported with the use of ARRANON®. These adverse reactions have included altered mental states including severe somnolence, central nervous system effects including convulsions, and peripheral neuropathy ranging from numbness and paresthesias to motor weakness and paralysis. There have also been reports of adverse reactions associated with demyelination, and ascending peripheral neuropathies similar in appearance to Guillain-Barré syndrome.
Full recovery from these adverse reactions has not always occurred with cessation of therapy with ARRANON. * Close monitoring for neurologic adverse reactions is strongly recommended, and ARRANON should be discontinued for neurologic adverse reactions of NCI Common Toxicity Criteria Grade 2 or greater.

Neurologic Adverse Reactions
Severe neurologic adverse reactions have been reported with the use of ARRANON®. These adverse reactions have included altered mental states including severe somnolence, central nervous system effects including convulsions, and peripheral neuropathy ranging from numbness and paresthesias to motor weakness and paralysis. There have also been reports of adverse reactions associated with demyelination, and ascending peripheral neuropathies similar in appearance to Guillain-Barré syndrome.
Full recovery from these adverse reactions has not always occurred with cessation of therapy with ARRANON. * Close monitoring for neurologic adverse reactions is strongly recommended, and ARRANON should be discontinued for neurologic adverse reactions of NCI Common Toxicity Criteria Grade 2 or greater.
5.1 Neurologic Adverse Reactions
Neurotoxicity is the dose-limiting toxicity of nelarabine. Patients undergoing therapy with ARRANON should be closely observed for signs and symptoms of neurologic toxicity [see Boxed Warning, Dosage and Administration (2.2)]. Common signs and symptoms of nelarabine-related neurotoxicity include somnolence, confusion, convulsions, ataxia, paresthesias, and hypoesthesia. Severe neurologic toxicity can manifest as coma, status epilepticus, craniospinal demyelination, or ascending neuropathy similar in presentation to Guillain-Barré syndrome.
Patients treated previously or concurrently with intrathecal chemotherapy or previously with craniospinal irradiation may be at increased risk for neurologic adverse events.
5.2 Hematologic Adverse Reactions
Leukopenia, thrombocytopenia, anemia, and neutropenia, including febrile neutropenia, have been associated with nelarabine therapy. Complete blood counts including platelets should be monitored regularly [see Dosage and Administration (2.2), Adverse Reactions (6.1)].
5.3 Pregnancy
Pregnancy Category D
ARRANON can cause fetal harm when administered to a pregnant woman.
Nelarabine administered during the period of organogenesis caused increased incidences of fetal malformations, anomalies, and variations in rabbits (see Use in Specific Populations (8.1)].
There are no adequate and well-controlled studies of ARRANON in pregnant women. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus. Women of child-bearing potential should be advised to avoid becoming pregnant while receiving treatment with ARRANON.
5.4 Hyperuricemia
Patients receiving ARRANON should receive intravenous hydration according to standard medical practice for the management of hyperuricemia in patients at risk for tumor lysis syndrome. Consideration should be given to the use of allopurinol in patients at risk of hyperuricemia [see Dosage and Administration (2.4)].
5.5 Vaccinations
Administration of live vaccines to immunocompromised patients should be avoided.
Precautions
Description
Adverse Reactions
Clinical Trials Experience
The following serious adverse reactions are discussed in greater detail in other sections of the label:
Neurologic [see Boxed Warning, Warnings and Precautions (5.1)]
Hematologic [see Warnings and Precautions (5.2)]
Hyperuricemia [see Warnings and Precautions (5.4)]
6.1 Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared with rates in the clinical trials of another drug and may not reflect the rates observed in practice.
ARRANON was studied in 459 patients in Phase I and Phase II clinical trials.
Adults: The safety profile of ARRANON is based on data from 103 adult patients treated with the recommended dose and schedule in 2 studies: an adult T-cell acute lymphoblastic leukemia (T-ALL)/T-cell lymphoblastic lymphoma (T-LBL) trial and an adult chronic lymphocytic leukemia trial.
The most common adverse reactions in adults, regardless of causality, were fatigue; gastrointestinal (GI) disorders (nausea, diarrhea, vomiting, and constipation); hematologic disorders (anemia, neutropenia, and thrombocytopenia); respiratory disorders (cough and dyspnea); nervous system disorders (somnolence and dizziness); and pyrexia.
The most common adverse reactions in adults, by System Organ Class, regardless of causality, including severe or life-threatening adverse reactions (NCI Common Toxicity Criteria Grade 3 or Grade 4) and fatal adverse reactions (Grade 5) are shown in Table 1.

Administration and Monitoring
Administration
2.1 Recommended Dosage
This product is for intravenous use only.
The recommended duration of treatment for adult and pediatric patients has not been clearly established. In clinical trials, treatment was generally continued until there was evidence of disease progression, the patient experienced unacceptable toxicity, the patient became a candidate for bone marrow transplant, or the patient no longer continued to benefit from treatment.
Adult Dosage: The recommended adult dose of ARRANON is 1,500 mg/m² administered intravenously over 2 hours on Days 1, 3, and 5 repeated every 21 days. ARRANON is administered undiluted.
Pediatric Dosage: The recommended pediatric dose of ARRANON is 650 mg/m² administered intravenously over 1 hour daily for 5 consecutive days repeated every 21 days. ARRANON is administered undiluted.
2.2 Dosage Modification
Administration of ARRANON should be discontinued for neurologic adverse reactions of NCI Common Toxicity Criteria Grade 2 or greater. Dosage may be delayed for other toxicity including hematologic toxicity. [See Boxed Warning, Warnings and Precautions (5.1, 5.2).]
2.3 Adjustment of Dose in Special Populations
ARRANON has not been studied in patients with renal or hepatic dysfunction [see Use in Specific Populations (8.6, 8.7)]. No dose adjustment is recommended for patients with a creatinine clearance (CLcr) ≥50 mL/min [see Clinical Pharmacology (12.3)]. There are insufficient data to support a dose recommendation for patients with a CLcr <50 mL/min.
2.4 Prevention of Hyperuricemia
Appropriate measures (e.g., hydration, urine alkalinization, and prophylaxis with allopurinol) must be taken to prevent hyperuricemia [see Warnings and Precautions (5.4)].
2.5 Instructions for Handling, Preparation, and Administration
Handling: ARRANON is a cytotoxic agent. Caution should be used during handling and preparation. Use of gloves and other protective clothing to prevent skin contact is recommended. Proper aseptic technique should be used. Guidelines for proper handling and disposal of anticancer drugs have been published.1-4
Preparation and Administration: Do not dilute ARRANON prior to administration. The appropriate dose of ARRANON is transferred into polyvinylchloride (PVC) infusion bags or glass containers and administered as a 2-hour infusion in adult patients and as a 1-hour infusion in pediatric patients.
