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 granulocyte-macrophage colony-stimulating factor (GM-CSF), interleukin-2 (IL-2), and 13-cis-retinoic acid (RA).
Treatment commenced within 95 days post autologous stem cell transplant in Study 1, within 210 days of autologous stem cell transplant in Study 2, and within 110 days of autologous stem cell transplant in Study
Study 1 In a randomized, open-label, multicenter study (Study 1), 134 patients received Unituxin in combination with GM-CSF, IL-2, and RA (Unituxin/RA group), including 109 randomized patients and 25 patients with biopsy-proven residual disease who were non-randomly assigned to receive Unituxin.
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.
Like all medications, Unituxin can cause side effects. However, not everyone who takes this medication will experience them. Many side effects are dose-dependent and may improve as your body adjusts to the medication. Others may require dose adjustment or medical attention.
