Obecabtagene Autoleucel

1 INDICATION AND USAGE AUCATZYL is indicated for the treatment of adults with relapsed or refractory B-cell precursor acute lymphoblastic leukemia (ALL). AUCATZYL is a CD19-directed genetically modified autologous T cell immunotherapy indicated for the treatment of adults with relapsed or refractory B-cell precursor acute lymphoblastic leukemia (ALL) ( 1 ).

6 ADVERSE REACTIONS The most common (non-laboratory) adverse reactions (incidence ≥ 20%) are: CRS, infections - pathogen unspecified, musculoskeletal pain, viral infections, fever, nausea, bacterial infectious disorders, diarrhea, febrile neutropenia, ICANS, hypotension, pain, fatigue, headache, encephalopathy, and hemorrhage ( 6.1 ). To report SUSPECTED ADVERSE REACTIONS, contact Autolus Inc at toll-free phone 1-855-288-5227 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch ( 17 ). 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 the rates observed in practice.

8.1 Pregnancy Risk Summary There are limited available data with AUCATZYL use in pregnant women. In the FELIX study, one patient became pregnant 6 months following treatment with AUCATZYL. The patient had a premature delivery at 30 weeks of pregnancy. No animal reproductive and developmental toxicity studies have been conducted with AUCATZYL to assess whether AUCATZYL can cause fetal harm when administered to a pregnant woman. It is not known if AUCATZYL has the potential to be transferred to the fetus and cause fetal toxicity.

WARNING: CYTOKINE RELEASE SYNDROME, NEUROLOGIC TOXICITIES, and SECONDARY HEMATOLOGICAL MALIGNANCIES Cytokine Release Syndrome (CRS) occurred in patients receiving AUCATZYL. Do not administer AUCATZYL to patients with active infection or inflammatory disorders. Prior to administering AUCATZYL, ensure that healthcare providers have immediate access to medications and resuscitative equipment to manage CRS [see Dosage and Administration (2.2 , 2.3) , Warnings and Precautions (5.1) ]. 5 WARNINGS AND PRECAUTIONS Prolonged Cytopenias: Patients may exhibit Grade 3 or higher cytopenias for several weeks following AUCATZYL infusion. Monitor complete blood counts ( 5.3 ). Infections: Monitor patients for signs and symptoms of infection; treat appropriately ( 5.4 ). Hypogammaglobulinemia: Monitor and consider immunoglobulin replacement therapy ( 5.5 ). Hemophagocytic Lymphohistiocytosis/ Macrophage Activation Syndrome: Administer treatment per institutional standards ( 5.6 ). Hypersensitivity Reactions: Monitor for hypersensitivity reactions during infusion ( 5.7 ). Secondary Malignancies: T cell malignancies have occurred following treatment of hematologic malignancies with BCMA- and CD19-directed genetically modified autologous T cell immunotherapies. 4 CONTRAINDICATIONS None. None ( 4 ).
