boxed warning
WARNING: SERIOUS INFUSION REACTIONS AND NEUROTOXICITY WARNING: SERIOUS INFUSION REACTIONS AND NEUROTOXICITY See full prescribing information for complete boxed warning. Infusion Reactions: Life-threatening infusion adverse reactions occur with Unituxin. Administer required prehydration and premedication. Immediately interrupt for severe infusion reactions and permanently discontinue for anaphylaxis [see Dosage and Administration (2.2 , 2.3) and Warnings and Precautions (5.1) ] . Neurotoxicity: Unituxin causes severe neuropathic pain. Administer intravenous opioid prior to, during, and for 2 hours following completion of the Unituxin infusion. Severe peripheral sensory neuropathy ranged from 2% to 9% in patients with neuroblastoma. Severe peripheral motor neuropathy has also been reported. Discontinue for severe unresponsive pain, severe sensory neuropathy, and moderate to severe peripheral motor neuropathy [see Dosage and Administration (2.2 , 2.3) and Warnings and Precautions (5.2) ] . Infusion Reactions Serious and potentially life-threatening infusion reactions occurred in 26% of patients treated with Unituxin. Administer required prehydration and premedication including antihistamines prior to each Unituxin infusion. Monitor patients closely for signs and symptoms of an infusion reaction during and for at least four hours following completion of each Unituxin infusion. Immediately interrupt Unituxin for severe infusion reactions and permanently discontinue Unituxin for anaphylaxis ( 2.2, 2.3, 5.1 ). Neurotoxicity Unituxin causes serious neurologic adverse reactions including severe neuropathic pain and peripheral neuropathy. Severe neuropathic pain occurs in the majority of patients. Administer intravenous opioid prior to, during, and for 2 hours following completion of the Unituxin infusion. In clinical studies of patients with high-risk neuroblastoma, Grade 3 peripheral sensory neuropathy occurred in 2% to 9% of patients. In clinical studies of Unituxin and related GD2-binding antibodies, severe motor neuropathy has occurred. Resolution of motor neuropathy did not occur in all cases. Discontinue Unituxin for severe unresponsive pain, severe sensory neuropathy, and moderate to severe peripheral motor neuropathy ( 2.2, 2.3, 5.2 ).

warnings and cautions
5 WARNINGS AND PRECAUTIONS Neurological Disorders of the Eye: Interrupt Unituxin for dilated pupil with sluggish light reflex or other visual disturbances and permanently discontinue Unituxin for recurrent eye disorders or loss of vision. ( 5.2 ) Prolonged Urinary Retention and Transverse Myelitis: Permanently discontinue Unituxin and institute supportive care. ( 5.2 ) Reversible Posterior Leukoencephalopathy Syndrome (RPLS): Permanently discontinue Unituxin and institute supportive care for signs and symptoms of RPLS. ( 5.2 ) Capillary Leak Syndrome and Hypotension: Administer required prehydration and monitor patients closely during treatment. Depending upon severity, manage by interruption, infusion rate reduction, or permanent discontinuation. ( 5.3 , 5.4 ) Infection: Interrupt until resolution of systemic infection. ( 5.5 ) Bone Marrow Suppression: Monitor peripheral blood counts during Unituxin therapy. ( 5.6 ) Electrolyte Abnormalities: Monitor serum electrolytes closely. ( 5.7 ) Atypical Hemolytic Uremic Syndrome: Permanently discontinue Unituxin and institute supportive management. ( 5.8 ) Embryo-Fetal Toxicity: May cause fetal harm. Advise females of reproductive potential of potential risk to a fetus and to use effective contraception. ( 5.9 , 8.1 , 8.3 ) 5.1 Serious Infusion Reactions Serious infusion reactions requiring urgent intervention, including blood pressure support, bronchodilator therapy, corticosteroids, infusion rate reduction, infusion interruption, or permanent discontinuation of Unituxin, included facial and upper airway edema, dyspnea, bronchospasm, stridor, urticaria, and hypotension. Infusion reactions generally occurred during or within 24 hours of completing the Unituxin infusion. Due to overlapping signs and symptoms, it was not possible to distinguish between infusion reactions and hypersensitivity reactions in some cases. In Study 1, Severe (Grade 3 or 4) infusion reactions occurred in 35 (26%) patients in the Unituxin/13-cis-retinoic acid (RA) group compared to 1 (1%) patient receiving RA alone. Severe urticaria occurred in 17 (13%) patients in the Unituxin/RA group but did not occur in the RA group. Serious adverse reactions consistent with anaphylaxis and resulting in permanent discontinuation of Unituxin occurred in 2 (1%) patients in the Unituxin/RA group. Additionally, 1 (0.1%) patient had multiple cardiac arrests ...

6 ADVERSE REACTIONS The following adverse reactions are discussed in greater detail in other sections of the labeling: Serious Infusion Reactions [see Boxed Warning and Warnings and Precautions (5.1) ] Neurotoxicity, including Pain, Peripheral Neuropathy, Neurological Disorders of the Eye, Prolonged Urinary Retention, Transverse Myelitis, and Reversible Posterior Leukoencephalopathy Syndrome [see Boxed Warning and Warnings and Precautions (5.2) ] Capillary Leak Syndrome [see Warnings and Precautions (5.3) ] Hypotension [see Warnings and Precautions (5.4) ] Infection [see Warnings and Precautions (5.5) ] Bone Marrow Suppression [see Warnings and Precautions (5.6) ] Electrolyte Abnormalities [see Warnings and Precautions (5.7) ] Atypical Hemolytic Uremic Syndrome [see Warnings and Precautions (5.8) ] Embryo-Fetal Toxicity [see Warnings and Precautions (5.9) ] The most common adverse drug reactions (≥25%) are pain, pyrexia, thrombocytopenia, lymphopenia, infusion reactions, hypotension, hyponatremia, increased alanine aminotransferase, anemia, vomiting, diarrhea, hypokalemia, capillary leak syndrome, neutropenia, urticaria, hypoalbuminemia, increased aspartate aminotransferase, and hypocalcemia. ( 5 , 6.1 ) The most common serious adverse reactions (≥5%) are infections, infusion reactions, hypokalemia, hypotension, pain, fever, and capillary leak syndrome. ( 5 , 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact United Therapeutics Corp. at 1-866-458-6479 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 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 to rates in the clinical trials of another drug and may not reflect rates observed in clinical practice. The data described below reflect exposure to Unituxin at the recommended dose and schedule in 1021 patients with high-risk neuroblastoma enrolled in an open-label, randomized (Study 1), or single-arm clinical trials (Study 2 and Study 3). Prior to enrollment, patients received therapy consisting of induction combination chemotherapy, maximum feasible surgical resection, myeloablative consolidation chemotherapy followed by autologous stem cell transplant, and radiation therapy to residual soft tissue disease. Patients received Unituxin in combination with granulo...
