U.S. Food and Drug Administration Approves Bristol Myers Squibb’s Breyanzi as a New CAR T Cell Therapy for Relapsed or Refractory Mantle Cell Lymphoma

Bristol Myers Squibb (NYSE: BMY) today announced the U.S. Food and Drug Administration (FDA) has granted 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 mantle cell lymphoma (MCL) who have received at least two prior lines of systemic therapy, including a Bruton tyrosine kinase (BTK) inhibitor. This FDA approval marks the fourth distinct subtype of non-Hodgkin lymphoma for which Breyanzi is approved, making it the CAR T cell therapy available to treat the broadest array of B-cell malignancies. In relapsed or refractory MCL, 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.

“With Breyanzi, we are delivering on the promise of cell therapy by offering a definitive treatment option for some of the most difficult-to-treat lymphomas,” said Bryan Campbell, senior vice president, Head of Commercial, Cell Therapy, Bristol Myers Squibb. “We are proud of the advances we are making to bring our differentiated CAR T cell therapy to the most patients across indications and lines of therapy to ensure treatment options that provide improved outcomes are available when most needed.”

MCL is a rare but aggressive form of non-Hodgkin lymphoma, and many patients relapse or become resistant to frontline therapies. Currently, MCL is considered an incurable disease, and response rates and duration of response tend to decrease with each additional relapse.

“There have been few advances in the treatment of relapsed or refractory MCL, and prognosis worsens for patients after each subsequent relapse, often leaving them with high disease burden and difficulty achieving deep and durable responses,” said Michael Wang, M.D., lead investigator and Puddin Clarke Endowed Professor, Department of Lymphoma and Myeloma, Division of Cancer Medicine, University of Texas MD Anderson Cancer Center, Houston, Texas. “The approval of Breyanzi offers an important new CAR T treatment option with high rates of lasting responses and a consistent safety profile, which is critically important for these patients who currently have limited options to treat this aggressive disease.”

The approval of Breyanzi is based on results from the MCL cohort of TRANSCEND NHL 001, which enrolled adults with relapsed or refractory MCL who had previously received at least two or more prior lines of therapy, including a BTK inhibitor. Based on the U.S. Prescribing Information (USPI), in patients treated with Breyanzi and evaluated for efficacy (n=68), 85.3% (95% CI: 74.6-92.7) responded to treatment, with 67.6% (95% CI: 55.2-78.5) achieving a complete response (CR). Responses were assessed per the 2014 Lugano classification and required bone marrow biopsy to confirm CR. Responses were rapid and durable with a median time to response of one month (range: 0.7-3) and median duration of response of 13.3 months (95% CI: 6.0-23.3) with a median follow-up of 22.2 months (95% CI: 16.7-22.8). More than half (51.4%; 95% CI: 37.5-63.7) of responders remained in response at 12 months, and 38.8% (95% CI: 25-52.4) of responders remained in response at 18 months. Results from the primary analysis published in the Journal of Clinical Oncology (JCO) (n=83; DL1 + DL2) showed an overall response rate of 83.1% (95% CI: 73.3-90.5) and a CR rate of 72.3% (95% CI: 61.4 to 81.6). Median duration of response was 15.7 months (95% CI: 6.2 to 24.0) and progression-free survival was 15.3 months (95% CI: 6.6 to 24.9).

Breyanzi has exhibited a consistent safety profile across clinical trials (n=702) with any grade cytokine release syndrome (CRS) occurring in 54% of patients, including Grade >3 CRS in 3.2% of patients. The median time to onset was 5 days (range: 1 to 63 days). Any grade neurologic events (NEs) were reported in 31% of patients, including Grade >3 in 10% of patients. The median time to onset of NEs was 8 days (range: 1 to 63 days). NEs resolved in 88% of patients with a median duration of 7 days (range: 1 to 119 days). The safety profile of Breyanzi allows for the option of outpatient treatment and management of patients. Breyanzi was administered in the inpatient and outpatient setting in the MCL cohort of TRANSCEND NHL 001.

“The approval of Breyanzi brings a new CAR T cell therapy option to patients battling relapsed or refractory MCL,” said Meghan Gutierrez, chief executive officer, Lymphoma Research Foundation. “Each advance in treatment represents important progress in improving outcomes for patients, and this news builds upon this progress with a new potentially transformative treatment where there are currently limited options. We are thankful for the families and the researchers involved in making this approval a reality for those living with this disease.”

To support this additional indication for Breyanzi, Bristol Myers Squibb has made continuous investments to increase manufacturing capacity and is prepared to meet demand for Breyanzi.

Breyanzi is broadly covered by commercial and government insurance programs in the U.S. 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.

*Treatment process includes leukapheresis, manufacturing, administration and adverse event monitoring.

About TRANSCEND NHL 001

TRANSCEND NHL 001 (NCT02631044) is an open-label, multicenter, pivotal, Phase 1, single-arm, seamless-design study to determine the safety, pharmacokinetics and antitumor activity of Breyanzi in patients with relapsed or refractory B-cell non-Hodgkin lymphoma, including diffuse large B-cell lymphoma, high-grade B-cell lymphoma, primary mediastinal B-cell lymphoma, follicular lymphoma Grade 3B and mantle cell lymphoma. The primary outcome measures are treatment-related adverse events, dose-limiting toxicities and overall response rate. Secondary outcome measures include complete response rate, duration of response, and progression-free survival.

About MCL

Mantle cell lymphoma (MCL) is an aggressive, rare form of non-Hodgkin lymphoma (NHL), representing roughly 3% of all NHL cases. MCL originates from cells in the “mantle zone” of the lymph node. MCL occurs more frequently in older adults with an average age at diagnosis in the mid-60s, and it is more often found in males than in females. In MCL, relapse after initial treatment is common, and for most, the disease eventually progresses or returns.

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 has 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, and relapsed or refractory follicular lymphoma in the third-line plus setting. Breyanzi is also approved in Japan, the European Union (EU), and Switzerland for the second-line treatment of relapsed or refractory LBCL, and in Japan, the EU, 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 clinicaltrials.gov.

Important Safety Information

WARNING: CYTOKINE RELEASE SYNDROME, NEUROLOGIC TOXICITIES, AND SECONDARY HEMATOLOGICAL MALIGNANCIES

  • Cytokine Release Syndrome (CRS), including fatal or life-threatening reactions, occurred in patients receiving Breyanzi. Do not administer Breyanzi to patients with active infection or inflammatory disorders. Treat severe or life-threatening CRS with tocilizumab with or without corticosteroids.
  • Neurologic toxicities, including fatal or life-threatening reactions, occurred in patients receiving Breyanzi, including concurrently with CRS, after CRS resolution, or in the absence of CRS. Monitor for neurologic events after treatment with Breyanzi. Provide supportive care and/or corticosteroids as needed.
  • T cell malignancies have occurred following treatment of hematologic malignancies with BCMA- and CD19-directed genetically modified autologous T cell immunotherapies, including Breyanzi.
  • Breyanzi is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the Breyanzi REMS.

Cytokine Release Syndrome

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 702 patients with non-Hodgkin lymphoma (NHL), CRS occurred in 54% of patients, including ≥ Grade 3 CRS in 3.2% of patients. The median time to onset was 5 days (range: 1 to 63 days). CRS resolved in 98% of patients with a median duration of 5 days (range: 1 to 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%) 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 88% of patients with a median duration of 7 days (range: 1 to 119 days). Of patients developing neurotoxicity, 82% 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:

  • Healthcare facilities that dispense and administer Breyanzi must be enrolled and comply with the REMS requirements.
  • Certified healthcare facilities must have on-site, immediate access to tocilizumab.
  • Ensure that a minimum of 2 doses of tocilizumab are available for each patient for infusion within 2 hours after Breyanzi infusion, if needed for treatment of CRS.

Further information is available at www.BreyanziREMS.com, or contact Bristol-Myers Squibb at 1-866-340-7332.

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 34% 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 3.7%, viral infections in 2%, and fungal infections in 0.7% of patients. One patient who received 4 prior lines of therapy developed a fatal case of John Cunningham (JC) virus progressive multifocal leukoencephalopathy 4 months after treatment with Breyanzi. One patient who received 3 prior lines of therapy developed a fatal case of cryptococcal meningoencephalitis 35 days 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, 35 of 38 patients with a 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 35% of patients, and included thrombocytopenia in 25%, neutropenia in 22%, and anemia in 6% of patients. Monitor complete blood counts prior to and after Breyanzi administration.

Hypogammaglobulinemia

B-cell aplasia and hypogammaglobulinemia can occur in patients receiving 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 30% 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-Like Syndrome (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.

Adverse Reactions

The most common adverse reaction(s) (incidence ≥30%) in:

  • LBCL are fever, cytokine release syndrome, fatigue, musculoskeletal pain, and nausea. The most common Grade 3-4 laboratory abnormalities include lymphocyte count decrease, neutrophil count decrease, platelet count decrease, and hemoglobin decrease.
  • CLL/SLL are cytokine release syndrome, encephalopathy, fatigue, musculoskeletal pain, nausea, edema, and diarrhea. The most common Grade 3-4 laboratory abnormalities include neutrophil count decrease, white blood cell decrease, hemoglobin decrease, platelet count decrease, and lymphocyte count decrease.
  • FL is cytokine release syndrome. The most common Grade 3-4 laboratory abnormalities include lymphocyte count decrease, neutrophil count decrease, and white blood cell decrease.
  • MCL are cytokine release syndrome, fatigue, musculoskeletal pain, and encephalopathy. The most common Grade 3-4 laboratory abnormalities include neutrophil count decrease, white blood cell decrease, and platelet count decrease.
