The following adverse reactions are described elsewhere in the labeling:

  • Cytokine Release Syndrome [see WARNINGS AND PRECAUTIONS]
  • Neurologic Toxicities [see WARNINGS AND PRECAUTIONS]

  • Hypogammaglobulinemia [see WARNINGS AND PRECAUTIONS]

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.

The safety data described in this section reflect exposure to BREYANZI in the TRANSCEND study, in which 268 adult patients with R/R large B-cell lymphoma received a flat dose of CAR-positive viable T cells [see Clinical Studies]. Patients with a history of CNS disorders (such as seizures or cerebrovascular ischemia) or autoimmune disease requiring systemic immunosuppression were ineligible. The median duration of follow-up was 9 months. The median age of the study population was 63 years (range: 18 to 86 years); 65% were male. The Eastern Cooperative Oncology Group (ECOG) performance status at screening was 0 in 41% of patients, 1 in 58% of patients, and 2 in 1.5% of patients.

Serious adverse reactions occurred in 46% of patients. The most common nonlaboratory, serious adverse reactions (> 2%) were CRS, encephalopathy, sepsis, febrile neutropenia, aphasia, pneumonia, fever, hypotension, dizziness, and delirium. Fatal adverse reactions occurred in 4% of patients.

Table 3 presents the adverse reactions reported in at least 10% of patients treated with BREYANZI, and Table 4 describes the laboratory abnormalities of Grade 3 or 4 that occurred in at least 10% of patients.

The most common nonlaboratory adverse reactions of any grade (≥ 20%) were fatigue, CRS, musculoskeletal pain, nausea, headache, encephalopathy, infections (pathogen unspecified), decreased appetite, diarrhea, hypotension, tachycardia, dizziness, cough, constipation, abdominal pain, vomiting, and edema.

BREYANZI has the potential to induce anti-product antibodies. The immunogenicity of BREYANZI has been evaluated using an electrochemiluminescence (ECL) immunoassay for the detection of binding antibodies against the extracellular CD19-binding domain of BREYANZI. Preexisting anti-product antibodies were detected in 11% (28/261) of patients. Treatment-induced or treatment-boosted anti-product antibodies were detected in 11% (27/257) of patients. Due to the small number of patients who had anti-product antibodies, the relationship between anti-product antibody status and efficacy, safety, or pharmacokinetics was not conclusive.
