Breyanzi®: THE ONE with a safety profile in 3L+ MCL that builds on evidence seen in clinical trials and other lymphoma indications1

In both clinical trials and the real-world setting, most CRS and NT events occurred and resolved quickly.1,2

In pivotal clinical trials (N=702)1,2

Across clinical trials of Breyanzi (N=702), 54% of patients experienced Any Grade CRS and 3.2% of patients experienced Grade ≥3 CRS. Median time to onset of CRS was 5 (range: 1-63) days; median duration was 5 (range: 1-37) days1

Any Grade CRS occurred in 54% of patients. 1% of patients experienced Grade ≥3 CRS at onset.
5 median days to onset.
5 median days of duration. 98% of CRS events occurred within 2 weeks after infusion.

No Grade 5 CRS events in pivotal clinical trials2

In the real-world setting (N=877)2

Any Grade CRS occurred in 49% of patients. Grade ≥3 CRS occurred in 2.7% of patients.
4 median days to onset.
4 median days of duration. 97% of CRS events occurred within 2 weeks after infusion.

Analysis limitations: Real-world data outcomes should be interpreted with caution. Analyses not intended to be compared to controlled clinical trial data. Causality cannot be established based on real-world data. Results may not be generalizable to other disease states or cell therapy products.

CRS-related clinical trial details (N=702)1,3

  • 29.5% of patients received tocilizumab and/or corticosteroids
  • 1.7% used corticosteroids only
  • 14.5% used tocilizumab only
  • Prophylactic systemic corticosteroids were not used in Breyanzi trials
  • CRS resolved in 98% of patients with a median duration of 5 (range: 1-37) days
  • One patient had fatal CRS and 5 patients had ongoing CRS at the time of death
  • The most common manifestations of CRS (≥10%) included fever, hypotension, chills, tachycardia, hypoxia, and headache

Cytokine release syndrome warnings and precautions1

  • CRS, including fatal or life-threatening reactions, occurred following treatment with Breyanzi
  • Serious events that may be associated with CRS include cardiac arrhythmias (including atrial fibrillation and ventricular tachycardia), cardiac arrest, cardiac failure, diffuse alveolar damage, renal insufficiency, capillary leak syndrome, hypotension, hypoxia, and hemophagocytic lymphohistiocytosis/macrophage activation syndrome
  • Ensure that 2 doses of tocilizumab are available prior to infusion of Breyanzi
  • Monitor patients daily for at least 7 days following Breyanzi infusion for signs and symptoms of CRS. Instruct patients to remain within proximity of a healthcare facility for at least 2 weeks to monitor for signs and symptoms of CRS. At the first sign of CRS, institute treatment with supportive care, tocilizumab, or tocilizumab and corticosteroids as indicated
  • Counsel patients to seek immediate medical attention should signs or symptoms of CRS occur at any time

Study design2

  • Data from pivotal trials (TRANSCEND NHL 001, TRANSCEND CLL 004, TRANSFORM, PILOT, and TRANSCEND FL) included patients treated with Breyanzi for R/R LBCL, CLL/SLL, MCL, and FL; data from the Center for International Blood and Marrow Transplant Research (CIBMTR) Registry included patients who received Breyanzi for R/R LBCL and had ≥1 assessment after infusion
  • Objectives of the study were to report CRS and NT rate and timing in patients treated with Breyanzi in pivotal clinical trials across indications or in the real-world standard of care (SoC) setting to inform safety monitoring requirements
  • Outcomes were incidence, onset, grade, and duration of CRS and NT from pivotal trials and the CIBMTR Registry

In pivotal clinical trials (N=702)1,2

Across clinical trials of Breyanzi (N=702), 31% of patients experienced Any Grade NT and 10% of patients experienced Grade ≥3 NT. Median time to onset for NT was 8 (range: 1-63) days; median duration was 7 (range: 1-119) days1

Any Grade NT occurred in 31% of patients. 4.6% of patients experienced Grade ≥3 NT at onset. 8 median days to onset. 7 median days of duration. 88% of NT events occurred within 2 weeks after infusion.

No Grade 5 NT events in pivotal clinical trials2

In the real-world setting (N=877)2

Any Grade NT occurred in 27% of patients. Grade ≥3 NT occurred in 10% of patients. 6 median days to onset. 5.5 median days of duration. 95% of NT events occurred within 2 weeks after infusion.

Analysis limitations: Real-world data outcomes should be interpreted with caution. Analyses not intended to be compared to controlled clinical trial data. Causality cannot be established based on real-world data. Results may not be generalizable to other disease states or cell therapy products.

NT-related clinical trial details (N=702)1

  • NTs resolved in 88% of cases with a median duration of 7 (range: 1-119) days
  • 82% of patients with NT developed CRS
  • The most common NTs (≥5%) included encephalopathy, tremor, aphasia, delirium, and headache

Neurologic toxicities warnings and precautions1

  • NTs that were fatal or life-threatening, including immune effector cell-associated neurotoxicity syndrome (ICANS), occurred following treatment with Breyanzi. Serious events including cerebral edema and seizures occurred with Breyanzi. Fatal and serious cases of leukoencephalopathy, some attributable to fludarabine, also occurred
  • Monitor patients daily for at least 7 days following Breyanzi infusion for signs and symptoms of NTs and assess for other causes of neurological symptoms. Instruct patients to remain within proximity of a healthcare facility for at least 2 weeks to monitor for signs and symptoms of NT. Manage NT with supportive care and/or corticosteroid as needed
  • Counsel patients to seek immediate medical attention should signs or symptoms of NT occur at any time

The most common adverse reactions observed in TRANSCEND MCL Cohort (N=88)1

  • Serious adverse reactions occurred in 53% of patients. The most common nonlaboratory serious adverse reactions (>2%) were CRS, confusional state, fever, encephalopathy, mental status changes, pleural effusion, upper respiratory tract infection, and decreased appetite. Fatal adverse reactions occurred in 4.5% of patients
  • One patient with MCL who received 3 prior lines of therapy developed a fatal case of cryptococcal meningoencephalitis 35 days after treatment with Breyanzi
  • The most common nonlaboratory adverse reactions (≥20%) were CRS, fatigue, musculoskeletal pain, encephalopathy, edema, headache, and decreased appetite

In clinical trials of Breyanzi (N=702)1

  • Grade ≥3 infections occurred in 12% of patients. Infections of any grade were reported in 34% of patients
