Breyanzi is specifically indicated for:
- adult patients with large B-cell lymphoma (LBCL), including diffuse large B-cell lymphoma (DLBCL) not otherwise specified (including DLBCL arising from indolent lymphoma), high-grade B-cell lymphoma, primary mediastinal large B-cell lymphoma, and follicular lymphoma grade 3B, who have:
- refractory disease to first-line chemoimmunotherapy or relapse within 12 months of first-line chemoimmunotherapy; or
- refractory disease to first-line chemoimmunotherapy or relapse after first-line chemoimmunotherapy and are not eligible for hematopoietic stem cell transplantation (HSCT) due to comorbidities or age; or
- relapsed or refractory disease after two or more lines of systemic therapy
- Adult patients with relapsed or refractory chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) who have received at least 2 prior lines of therapy, including a Bruton tyrosine kinase (BTK) inhibitor and a B-cell lymphoma 2 (BCL-2) inhibitor.
- Adult patients with relapsed or refractory follicular lymphoma (FL) who have received 2 or more prior lines of systemic therapy
- 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.
Dosing/Administration
Breyanzi is supplied as a single dose suspension for intravenous administration. A single dose of Breyanzi contains 50 to 110 × 106 CAR-positive viable T cells (consisting of 1:1 CAR-positive viable T cells of the CD8 and CD4 components), with each component supplied separately in one to four single-dose vial.
- The dose range for LBCL after two or more lines of therapy is 50 to 110 × 106 CAR-positive viable T cells
- The dose range for LBCL after one line of therapy and CLL or SLL is 90 to 110 × 106 CAR-positive viable T cells
- The dose range for MCL is a single dose containing 90 to 110 x 106 CAR-positive viable T cells
Breyanzi is for autologous use only. The patient’s identity must match the patient identifiers on the Breyanzi cartons, vials and syringe labels. Do not infuse Breyanzi if the information on the patient-specific labels does not match the intended patient.
- Preparing the Patient for Breyanzi: Confirm the availability of Breyanzi before starting lymphodepleting chemotherapy.
- Pretreatment: Administer the lymphodepleting chemotherapy regimen before infusion of Breyanzi: fludarabine 30 mg/m2 /day intravenously (IV), and cyclophosphamide 300 mg/m2 /day IV for 3 days. See the prescribing information for fludarabine and cyclophosphamide for information on dose adjustment in renal impairment. Infuse Breyanzi 2 to 7 days after completion of lymphodepleting chemotherapy. Delay the infusion of Breyanzi if the patient has unresolved serious adverse events from preceding chemotherapies, active uncontrolled infection, or active graft-versus-host disease (GVHD).
- Premedication: To minimize the risk of infusion reactions, pre-medicate the patient with acetaminophen (650 mg orally) and diphenhydramine (25-50 mg, IV or orally), or another H1-antihistamine, 30 to 60 minutes prior to treatment with Breyanzi. Avoid prophylactic use of systemic corticosteroids, as they may interfere with the activity of Breyanzi.
Please refer to the drug label for specific directions in the preparation and infusion of Breyanzi administration.
Mechanism of Action
Breyanzi (lisocabtagene maraleucel; liso-cel) is a CD19-directed genetically modified autologous cell immunotherapy administered as a defined composition to reduce variability in CD8-positive and CD4-positive T cell dose. The CAR is comprised of an FMC63 monoclonal antibody-derived single chain variable fragment (scFv), IgG4 hinge region, CD28 transmembrane domain, 4-1BB (CD137) costimulatory domain, and CD3 zeta activation domain. CD3 zeta signaling is critical for initiating activation and antitumor activity, while 4-1BB (CD137) signaling enhances the expansion T cell and persistence of BREYANZI. CAR binding to CD19 expressed on the cell surface of tumor and normal B cells induces activation and proliferation of CAR T cells, release of pro-inflammatory cytokines, and cytotoxic killing of target cells.
Side Effects
Adverse effects associated with the use of Breyanzi may include, but are not limited to, the following:
- fatigue
- cytokine release syndrome
- musculoskeletal pain
- nausea
- headache
- encephalopathy
- infections (pathogen unspecified)
- decreased appetite
- diarrhea
- hypotension
- tachycardia
- dizziness
- cough
- constipation
- abdominal pain
- vomiting
- edema
The Breyanzi drug label comes with the following Black Box Warning: CYTOKINE RELEASE SYNDROME and NEUROLOGIC TOXICITIES: 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. Breyanzi is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the Breyanzi REMS.
Indication 1 - for patients with relapsed or refractory large B-cell lymphoma after one or more lines of systemic therapy
approved February 2021
Clinical Trial Results
The FDA approval of Breyanzi was based on data from the TRANSCEND NHL 001, an open-label, multicenter, single-arm trial in adult patients with relapsed or refractory large B-cell non-Hodgkin lymphoma after at least 2 lines of therapy. In the study, 192 patients were treated with Breyanzi at the dose of 50 to 110 x 106 CAR-positive viable T cells and evaluated for efficacy. Of these patients, 73% achieved a response, including 54% who had minimal or no detectable lymphoma remaining following treatment and 19% who achieved a partial response. Median duration of response was 16.7 months in all responders, and for patients who achieved a CR, median duration of response was not reached; for patients with a best response of PR, median duration of response was 1.4 months. Of 104 patients treated with Breyanzi who achieved a best overall response of CR, 65% had remission lasting at least six months and 62% had remission lasting at least nine months.
The approval of the expanded first-line indications for Breyanzi is based on results from the pivotal Phase 3 TRANSFORM study in which adults with LBCL that was primary refractory or relapsed within 12 months of front-line therapy were randomized to receive Breyanzi or standard therapy consisting of salvage immunochemotherapy, and if responsive, high-dose chemotherapy and HSCT. The trial included patients with diverse histologic subtypes and high-risk features, and offered a patient-centric design, allowing for bridging immunochemotherapy in the Breyanziarm for disease control. Results from the TRANSFORM study showed, Breyanzi (n=92) more than quadrupled median EFS compared to standard therapy (n=92) (10.1 months vs. 2.3 months. The majority of patients achieved a CR with Breyanzi compared to less than half with standard therapy (66% vs. 39%) with median duration of CR not reached in the Breyanzi arm. Results also showed Breyanzi more than doubled PFS versus standard therapy (median PFS: 14.8 months vs. 5.7 months. In the study, nearly all patients (97%) in the Breyanzi arm received treatment versus less than half (47%) of patients who completed high-dose chemotherapy and autologous HSCT in the standard therapy arm.
Indication 2 - for adult patients with relapsed or refractory chronic lymphocytic leukemia or small lymphocytic lymphoma
approved March of 2024
Clinical Trial Results
The FDA granted accelerated approval or the treatment of adult patients with relapsed or refractory chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) who have received at least 2 prior lines of therapy including, a Bruton tyrosine kinase (BTK) inhibitor and a B-cell lymphoma 2 (BCL-2) inhibitor 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).
The Phase 1/2 open-label, single-arm TRANSCEND CLL 004 study was the first pivotal multicenter trial to evaluate a CAR T cell therapy in patients with relapsed or refractory CLL or SLL. The CR rate associated with Breyanzi treatment was 20%. Among patients who achieved a CR, median duration of response was not reached at the time of data cutoff. Among all responders (ORR = 45%) median duration of response was 35.3 months. High rates of minimal residual disease (MRD) negative status were observed across patients treated with Breyanzi who achieved a CR, with an MRD-negativity rate of 100% in the blood and 92.3% in the bone marrow.
Indication 3 - adult patients with relapsed or refractory follicular lymphoma (FL) who have received 2 or more prior lines of systemic therapy
approved May of 2024
Clinical Trial Results
The FDA approval was based on the Phase 2 TRANSCEND FL study. 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%. The complete response (CR) rate was 73.4% and required a negative bone marrow biopsy for confirmation. Responses were rapid and durable with a median time to response of one month and median duration of response (DOR) not reached, with 80.9% of responders remaining in response at 12 months, and 77.1% of responders remaining in response at 18 months.
Indication 4 - adult patients with relapsed or refractory mantle cell lymphoma (MCL) who have received at least two prior lines of systemic therapy
approved May of 2024
Clinical Trial Results
Clinical Trial Results
The FDA approval of Breyanzi for adults 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 was based on results from the MCL cohort of TRANSCEND NHL 001. In patients treated with Breyanzi and evaluated for efficacy (n=68), 85.3% responded to treatment, with 67.6% 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 and median duration of response of 13.3 months with a median follow-up of 22.2 months. More than half of responders remained in response at 12 months, and 38.8% of responders remained in response at 18 months. Results from the primary analysis (n=83; DL1 + DL2) showed an overall response rate of 83.1% and a CR rate of 72.3%. Median duration of response was 15.7 months and progression-free survival was 15.3 months.
