5. Warnings and Precautions
⚠ Boxed Warning
CYTOKINE RELEASE SYNDROME (CRS): Fatal or life-threatening CRS occurred. Do not administer to patients with active infection or inflammatory disorders. Treat severe or life-threatening CRS with tocilizumab or tocilizumab and corticosteroids. NEUROLOGIC TOXICITIES: Fatal or life-threatening neurologic toxicities occurred. Monitor for and treat promptly. HEMOPHAGOCYTIC LYMPHOHISTIOCYTOSIS/MACROPHAGE ACTIVATION SYNDROME (HLH/MAS): Has occurred in patients. Overlapping symptoms with CRS. Treat promptly.
  • Cytokine Release Syndrome: Occurred in 93% of patients (9% Grade ≥3). Median onset: 2 days (range 1-12). Manage with tocilizumab ± corticosteroids.
  • Neurologic Toxicities (ICANS): Occurred in 64% (24% Grade ≥3). Including encephalopathy, aphasia, tremor, delirium, seizures, cerebral edema. Median onset: 5 days.
  • HLH/MAS: Potentially fatal. Monitor for and treat promptly.
  • Prolonged Cytopenias: Patients may exhibit cytopenias for several weeks. Grade 3+ cytopenias not resolved by Day 30: neutropenia (33%), thrombocytopenia (18%), anemia (12%).
  • Serious Infections: Fatal and life-threatening infections reported. Monitor and treat.
  • Hypogammaglobulinemia: Occurred in 14%. Monitor immunoglobulin levels and manage.
  • Secondary Malignancies: Including myeloid neoplasms and T-cell malignancies.

12. Clinical Pharmacology
Mechanism of Action

Axicabtagene ciloleucel is a CD19-directed genetically modified autologous T-cell immunotherapy. Patient T cells are collected via leukapheresis and genetically modified ex vivo using a retroviral vector to express a chimeric antigen receptor (CAR) comprising an anti-CD19 single-chain variable fragment (scFv) linked to CD28 costimulatory and CD3-zeta signaling domains. Upon infusion and engagement with CD19-expressing cells, the CAR T cells activate, proliferate, and eliminate CD19-positive target cells through direct cytotoxicity and cytokine release.

Pharmacokinetics

Peak CAR T-cell expansion: median 8-15 days post-infusion. CAR T cells detectable in blood for 6+ months (though declining). CD28 costimulatory domain drives rapid initial expansion. Higher Cmax correlated with Grade 3+ CRS and response.
