Bristol Myers Squibb’s CAR T Cell Therapy Breyanzi Approved by the U.S. Food and Drug Administration for Relapsed or Refractory Follicular Lymphoma

Bristol Myers Squibb (NYSE: BMY) today announced the U.S. Food and Drug Administration (FDA) has granted accelerated approval for Breyanzi ® (lisocabtagene maraleucel; liso-cel), a CD19-directed chimeric antigen receptor (CAR) T cell therapy, for the treatment of adult patients with relapsed or refractory follicular lymphoma (FL) who have received two or more prior lines of systemic therapy. This indication is approved under accelerated approval based on response rate and duration of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trial(s). Breyanzi is also now included in the National Comprehensive Cancer Network (NCCN®) Clinical Practice Guidelines in Oncology (NCCN Guidelines®) for B-cell Lymphomas as a Category 2A recommendation for third-line and subsequent therapy for relapsed or refractory FL.*

In relapsed or refractory FL, Breyanzi is delivered as a one-time infusion** with a single dose containing 90 to 110 x 106 CAR-positive viable T cells. Please see the Important Safety Information section below, including Boxed WARNINGS for Breyanzi regarding Cytokine Release Syndrome (CRS), Neurologic Toxicities, and Secondary Hematological Malignancies.

“Breyanzi is a cornerstone of our cell therapy portfolio, providing a differentiated profile across a wide array of B-cell malignancies,” said Bryan Campbell, senior vice president, Head of Commercial, Cell Therapy, Bristol Myers Squibb. “Today’s approval of Breyanzi for relapsed or refractory FL provides an option with potential for lasting remission in a one-time infusion and a safety profile that allows for administration and monitoring in both the inpatient and outpatient setting in an increasing number of certified treatment centers in the U.S.”

Historically, FL has been considered an incurable disease, and patients frequently relapse following front-line therapy, with prognosis worsening after each subsequent relapse. Despite advances in treatment, there remains an unmet need for additional options that offer treatment-free intervals with durable, complete responses.

The Phase 2 TRANSCEND FL study included the largest primary analysis set of patients with relapsed or refractory FL of a clinical trial evaluating a CAR T cell therapy in this patient population. Based on the U.S. Prescribing Information (USPI), in patients treated with Breyanzi in the third-line plus setting and included in the primary efficacy analysis set (n=94), the overall response rate (ORR) was 95.7% (95% CI: 89.5-98.8). ORR was defined as the percentage of patients achieving a partial or complete response per Lugano criteria as assessed by an Independent Review Committee (IRC). The complete response (CR) rate was 73.4% (95% CI: 63.3-82.0) and required a negative bone marrow biopsy for confirmation. Responses were rapid and durable with a median time to response of one month (range: 0.6-3.3) and median duration of response (DOR) not reached (95% CI: 18.04-NR), with 80.9% of responders remaining in response at 12 months, and 77.1% of responders remaining in response at 18 months. Results from the primary analysis of TRANSCEND FL presented at the 2023 International Conference on Malignant Lymphoma showed an ORR of 97% (95% CI: 91.6-99.4; one-sided p<0.0001) in efficacy evaluable patients (n=101), with 94% of patients achieving a CR (95% CI: 87.5-97.8; one-sided p<0.0001).

“In the treatment of relapsed or refractory follicular lymphoma, patients often cycle through treatments with typically shorter responses with each new line of therapy. Those who have experienced early disease progression have notably poor prognosis,” said M. Lia Palomba, M.D., TRANSCEND investigator and lymphoma and cell therapy specialist, Memorial Sloan Kettering Cancer Center. “The FDA approval of liso-cel for patients with relapsed or refractory FL is an important advancement in addressing an ongoing unmet need in the FL treatment paradigm, providing patients a new option that has shown remarkably high response rates and an established safety profile.”

Breyanzi has exhibited a consistent safety profile and across clinical trials, any grade cytokine release syndrome (CRS) occurred in 53% of patients, including Grade >3 CRS in 4% of patients. The median time to onset was 5 days (range: 1 to 63 days). Any grade neurologic events (NEs) occurred in 31% of patients, with Grade >3 NEs occurring in 10% of patients. The median time to onset of NEs was 8 days (range: 1 to 63 days). The safety profile of Breyanzi allows for the option of outpatient treatment and management of patients. Patients in the TRANSCEND FL study were treated in the inpatient and outpatient setting.

“The lymphoma community has felt an urgent need for advancements in the treatment of relapsed or refractory follicular lymphoma,” said Meghan Gutierrez, chief executive officer, Lymphoma Research Foundation. “The approval of Breyanzi offers patients a new and meaningful treatment option that provides hope for lasting remission, and we are grateful to those who have contributed to this exciting milestone for patients.”

Bristol Myers Squibb offers various programs and resources to address the needs of patients and caregivers, and provides support that allows for access to therapies, including Breyanzi. Bristol Myers Squibb also supports the patient and physician treatment experience by providing Cell Therapy 360, a digital service platform, which optimizes access to relevant information, manufacturing updates, and patient and caregiver support.

TRANSCEND FL (NCT04245839) is an open-label, global, multicenter, Phase 2, single-arm study to determine the efficacy and safety of Breyanzi in patients with relapsed or refractory indolent B-cell non-Hodgkin lymphoma, including follicular lymphoma. The primary outcome measure is overall response rate, including best overall response of complete response or partial response as determined by an Independent Review Committee. Secondary outcome measures include complete response rate, duration of response, progression-free survival, and safety.

About FL

Follicular lymphoma (FL) is the second most common form of non-Hodgkin lymphoma (NHL) and the most common subtype of indolent NHL, accounting for 20 to 30 percent of all NHL cases. The average age of diagnosis for FL is 65 years of age. FL develops when white blood cells cluster together to form lumps in a person’s lymph nodes or organs. It is characterized by periods of remission and relapse, and the disease becomes more difficult to treat after relapse or disease progression.

About Breyanzi

Breyanzi is a CD19-directed CAR T cell therapy with a 4-1BB costimulatory domain, which enhances the expansion and persistence of the CAR T cells. Breyanzi is made from a patient’s own T cells, which are collected and genetically reengineered to become CAR T cells that are then delivered via infusion as a one-time treatment.

Breyanzi is approved in the U.S. for the treatment of relapsed or refractory large B-cell lymphoma (LBCL) after at least one prior line of therapy and received accelerated approval for the treatment of relapsed or refractory chronic lymphocytic leukemia or small lymphocytic lymphoma after at least two prior lines of therapy. Breyanzi is also approved in Japan, the European Union (EU), and Switzerland for the second-line treatment or relapsed or refractory LBCL, and in Japan, the European Union, Switzerland, the UK and Canada for relapsed and refractory LBCL after two or more lines of systemic therapy.

Bristol Myers Squibb’s clinical development program for Breyanzi includes clinical studies in other types of lymphoma. For more information, visit

Limitations of Use: Breyanzi is not indicated for the treatment of patients with primary central nervous system lymphoma.

Important Safety Information


Cytokine Release Syndrome (CRS)

Cytokine release syndrome (CRS), including fatal or life-threatening reactions, occurred following treatment with Breyanzi. In clinical trials of Breyanzi which enrolled a total of 614 patients with non-Hodgkin lymphoma (NHL), CRS occurred in 53% of patients, including Grade 3 or higher CRS in 4% of patients. The median time to onset was 5 days (range: 1 to 63 days). CRS resolved in 98% of patients with median duration of 5 days (range: 1 to 37 days). The most common manifestations of CRS (>10%) were fever, hypotension, tachycardia, chills, hypoxia and headache.

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 (HLH/MAS).

Ensure that 2 doses of tocilizumab are available prior to infusion of Breyanzi.

Neurologic Toxicities

Neurologic toxicities 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.

In clinical trials of Breyanzi, CAR T cell-associated neurologic toxicities occurred in 31% of patients, including > Grade 3 cases in 10% of patients. The median time to onset of neurotoxicity was 8 days (range: 1 to 63 days). Neurologic toxicities resolved in 87% of patients with a median duration of 8 days (range: 1 to 119 days). Of patients developing neurotoxicity, 81% also developed CRS.

The most common neurologic toxicities (≥ 5%) included encephalopathy, tremor, aphasia, headache, dizziness, and delirium.

CRS and Neurologic Toxicities Monitoring

Monitor patients daily for at least 7 days following Breyanzi infusion at a REMS-certified healthcare facility for signs and symptoms of CRS and neurologic toxicities and assess for other causes of neurological symptoms. Monitor patients for signs and symptoms of CRS and neurologic toxicities for at least 4 weeks after infusion and treat promptly. At the first sign of CRS, institute treatment with supportive care, tocilizumab, or tocilizumab and corticosteroids as indicated. Manage neurologic toxicity with supportive care and/or corticosteroid as needed. Counsel patients to seek immediate medical attention should signs or symptoms of CRS or neurologic toxicity occur at any time.

Breyanzi REMS

Because of the risk of CRS and neurologic toxicities, Breyanzi is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the Breyanzi REMS. The required components of the Breyanzi REMS are:

Hypersensitivity Reactions

Allergic reactions may occur with the infusion of Breyanzi. Serious hypersensitivity reactions, including anaphylaxis, may be due to dimethyl sulfoxide (DMSO).

Serious Infections

Severe infections, including life-threatening or fatal infections, have occurred in patients after Breyanzi infusion. In clinical trials of Breyanzi, infections of any grade occurred in 33% of patients, with Grade 3 or higher infections occurring in 12% of all patients. Grade 3 or higher infections with an unspecified pathogen occurred in 7%, bacterial infections in 4%, viral infections in 2%, and fungal infections in 0.7% of patients. One patient who received four prior lines of therapy developed a fatal case of John Cunningham (JC) virus progressive multifocal leukoencephalopathy four months after treatment with Breyanzi.

Febrile neutropenia developed after Breyanzi infusion in 8% of patients. Febrile neutropenia may be concurrent with CRS. In the event of febrile neutropenia, evaluate for infection and manage with broad spectrum antibiotics, fluids, and other supportive care as medically indicated.

Monitor patients for signs and symptoms of infection before and after Breyanzi administration and treat appropriately. Administer prophylactic antimicrobials according to standard institutional guidelines. Avoid administration of Breyanzi in patients with clinically significant, active systemic infections.

Viral reactivation: Hepatitis B virus (HBV) reactivation, in some cases resulting in fulminant hepatitis, hepatic failure, and death, can occur in patients treated with drugs directed against B cells. In clinical trials of Breyanzi, 26 of 29 patients with prior history of HBV were treated with concurrent antiviral suppressive therapy. Perform screening for HBV, HCV, and HIV in accordance with clinical guidelines before collection of cells for manufacturing. In patients with prior history of HBV, consider concurrent antiviral suppressive therapy to prevent HBV reactivation per standard guidelines.

Prolonged Cytopenias

Patients may exhibit cytopenias not resolved for several weeks following lymphodepleting chemotherapy and Breyanzi infusion. In clinical trials of Breyanzi, Grade 3 or higher cytopenias persisted at Day 29 following Breyanzi infusion in 34% of patients, and included thrombocytopenia in 24%, neutropenia in 22%, and anemia in 7% of patients. Monitor complete blood counts prior to and after Breyanzi administration.


B-cell aplasia and hypogammaglobulinemia can occur in patients receiving treatment with Breyanzi. In clinical trials of Breyanzi, hypogammaglobulinemia was reported as an adverse reaction in 10% of patients. Hypogammaglobulinemia, either as an adverse reaction or laboratory IgG level below 500 mg/dL after infusion, was reported in 29% of patients. Monitor immunoglobulin levels after treatment with Breyanzi and manage using infection precautions, antibiotic prophylaxis, and immunoglobulin replacement as clinically indicated.

Live vaccines: The safety of immunization with live viral vaccines during or following Breyanzi treatment has not been studied. Vaccination with live virus vaccines is not recommended for at least 6 weeks prior to the start of lymphodepleting chemotherapy, during Breyanzi treatment, and until immune recovery following treatment with Breyanzi.

Secondary Malignancies

Patients treated with Breyanzi may develop secondary malignancies. T cell malignancies have occurred following treatment of hematologic malignancies with BCMA- and CD19-directed genetically modified autologous T cell immunotherapies, including Breyanzi. Mature T cell malignancies, including CAR-positive tumors, may present as soon as weeks following infusion, and may include fatal outcomes. Monitor lifelong for secondary malignancies. In the event that a secondary malignancy occurs, contact Bristol Myers Squibb at 1-888-805-4555 for reporting and to obtain instructions on collection of patient samples for testing.

Effects on Ability to Drive and Use Machines

Due to the potential for neurologic events, including altered mental status or seizures, patients receiving Breyanzi are at risk for developing altered or decreased consciousness or impaired coordination in the 8 weeks following Breyanzi administration. Advise patients to refrain from driving and engaging in hazardous occupations or activities, such as operating heavy or potentially dangerous machinery, for at least 8 weeks.

Immune Effector Cell-Associated Hemophagocytic Lymphohistiocytosis-Like Syndrome (IEC-HS)

Immune Effector Cell-Associated Hemophagocytic Lymphohistiocytosis (IEC-HS), including fatal or life-threatening reactions, occurred following treatment with Breyanzi. Three of 89 (3%) safety evaluable patients with R/R CLL/SLL developed IEC-HS. Time to onset of IEC-HS ranged from 7 to 18 days. Two of the 3 patients developed IEC-HS in the setting of ongoing CRS and 1 in the setting of ongoing neurotoxicity. IEC-HS was fatal in 2 of 3 patients. One patient had fatal IEC-HS and one had ongoing IEC-HS at time of death. IEC-HS is a life-threatening condition with a high mortality rate if not recognized and treated early. Treatment of IEC-HS should be administered per current practice guidelines.
