5 WARNINGS AND PRECAUTIONS

5.1 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 (Lee grading system1) 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%) included fever, hypotension, chills, tachycardia, 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) [see Adverse Reactions (6.1)].

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

Monitor patients daily for at least 7 days following BREYANZI infusion at a REMS-certified healthcare facility for signs and symptoms of CRS. Monitor patients for signs or symptoms of CRS for at least 4 weeks after infusion. At the first sign of CRS, institute treatment with supportive care, tocilizumab, or tocilizumab and corticosteroids as indicated [see Dosage and Administration (2.3)].

Counsel patients to seek immediate medical attention should signs or symptoms of CRS occur at any time [see Patient Counseling Information (17)].

5.2 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, delirium, and headache.

Monitor patients daily for at least 7 days following BREYANZI infusion at a REMS-certified healthcare facility for signs and symptoms of neurologic toxicities and assess for other causes of neurological symptoms. Monitor patients for signs or symptoms of neurologic toxicities for at least 4 weeks after infusion and treat promptly. Manage neurologic toxicity with supportive care and/or corticosteroid as needed [see Dosage and Administration (2.3)].

Counsel patients to seek immediate medical attention should signs or symptoms of neurologic toxicity occur at any time [see Patient Counseling Information (17)].

5.3 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 [see Boxed Warning and Warnings and Precautions (5.1, 5.2)]. The required components of the BREYANZI REMS are:

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

• •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.

5.4 Hypersensitivity Reactions

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

5.5 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 occurred 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 with FL, 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. One patient with MCL, who received three 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.

5.6 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.

5.7 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.

SPL UNCLASSIFIED SECTION

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.

5.8 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 [see Boxed Warning, Adverse Reactions (6.2), Patient Counseling Information (17)].  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.

5.9 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.

5.10 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.

The median age was 62 years (range: 23 to 80 years), 38 % were female, and ECOG performance status was 0 in 61% and 1 in 39% of patients; 56% were White, 3% were Black, 9% were Asian; 5% were Hispanic and 69% were non-Hispanic.

Serious adverse reactions occurred in 26% of patients. The most common nonlaboratory serious adverse reactions (> 2%) were CRS, aphasia, febrile neutropenia, fever, and tremor.

Table 12 presents selected nonlaboratory adverse reactions reported in patients treated with BREYANZI, and Table 13 describes selected new or worsening Grade 3 or 4 laboratory abnormalities.

The most common nonlaboratory adverse reactions (≥ 20%) were CRS, headache, musculoskeletal pain, fatigue, constipation, and fever.

Other clinically important adverse reactions in < 10% of patients included the following:

Grade 4 laboratory abnormalities in ≥ 10% of patients were lymphocyte count decreased  (78%), neutrophil count decreased (61%), white blood cell decreased (41%), and platelet count decreased (11%).

Relapsed or Refractory MCL

TRANSCEND-MCL Cohort

The safety of BREYANZI was evaluated in the TRANSCEND Study-MCL Cohort, in which 88 adult patients with relapsed or refractory MCL received a single dose of CAR-positive viable T cells [see Clinical Studies (14.4)]. Patients with a history of CNS disorders (such as seizures or cerebrovascular ischemia) or autoimmune disease requiring systemic immunosuppression were ineligible. The trial required left ventricular ejection fraction ≥ 40%, adequate oxygen saturation on room air with ≤ Grade 1 dyspnea, ALT ≤ 5 x ULN, total bilirubin < 2.0 mg/dL, creatinine clearance > 30 mL/min, and adequate bone marrow function to receive lymphodepleting chemotherapy. The median age of the study population was 69 years (range: 36 to 86 years); 76% were male, 88% were White, 6% were Asian and 2.3% were Black. Four percent were Hispanic, and 92% were non-Hispanic. The ECOG performance status at screening was 0 in 54% of patients, and 1 in 46% of patients.

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.

Table 14 presents selected nonlaboratory adverse reactions reported in patients treated with BREYANZI, and Table 15 describes selected new or worsening Grade 3 or 4 laboratory abnormalities.

The most common nonlaboratory adverse reactions (≥ 20%) were CRS, fatigue, musculoskeletal pain, encephalopathy, edema, headache, and decreased appetite.

Other clinically important adverse reactions in < 10% of patients included the following:

Grade 4 laboratory abnormalities in ≥ 10% of patients were lymphocyte count decreased (84%), neutrophil count decreased (52%), white blood cell decreased (52%), and platelet count decreased (22%).

• •Respiratory, thoracic, and mediastinal disorders: Dyspnea (8%)
• •Vascular disorders: Thrombosis (8%), hypertension (7%)

6.2 Postmarketing Experience

Because adverse events to marketed products are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to product exposure.

The following adverse events have been identified during postmarketing use of BREYANZI.

Nervous System Disorder: Immune effector cell-associated neurotoxicity syndrome (ICANS).

Neoplasms: T cell malignancies

7 DRUG INTERACTIONS

7.1 Drug-Laboratory Test Interactions

HIV and the lentivirus used to make BREYANZI have limited, short spans of identical genetic material (RNA). Therefore, some commercial HIV nucleic acid tests may yield false-positive results in patients who have received BREYANZI.

8 USE IN SPECIFIC POPULATIONS

8.1 Pregnancy

SPL UNCLASSIFIED SECTION

Risk Summary

There are no available data with BREYANZI use in pregnant women. No animal reproductive and developmental toxicity studies have been conducted with BREYANZI to assess whether it can cause fetal harm when administered to a pregnant woman.

It is not known if BREYANZI has the potential to be transferred to the fetus. Based on the mechanism of action, if the transduced cells cross the placenta, they may cause fetal toxicity, including B-cell lymphocytopenia and hypogammaglobulinemia. Therefore, BREYANZI is not recommended for women who are pregnant, and pregnancy after BREYANZI infusion should be discussed with the treating physician.

In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

8.2 Lactation

SPL UNCLASSIFIED SECTION

Risk Summary

There is no information regarding the presence of BREYANZI in human milk, the effect on the breastfed infant, and the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for BREYANZI and any potential adverse effects on the breastfed infant from BREYANZI or from the underlying maternal condition.

8.3 Females and Males of Reproductive Potential

SPL UNCLASSIFIED SECTION

Pregnancy Testing

Pregnancy status of females with reproductive potential should be verified. Sexually active females of reproductive potential should have a pregnancy test prior to starting treatment with BREYANZI.

In clinical trials of BREYANZI, 111 (41%) of 268 patients with two or more prior lines of therapy for LBCL, and 89 (59%) of 150 patients with one prior line of therapy for LBCL, were 65 years of age or older; 27 (10%) and 28 (19%) were 75 years of age or older, respectively. In patients with CLL/SLL, 51 (57%) of 89 were 65 years of age or older, and 9 (10%) were 75 years of age or older. In patients with FL, 42 (39%) of 107 were 65 years of age or older, and 10 (9%) were 75 years of age or older. In patients with MCL, 64 (73%) of 88 patients were 65 years of age or older, and 18 (21%) were 75 years of age or older. No clinically important differences in safety or effectiveness of BREYANZI were observed between patients aged ≥ 65 and younger patients.

11 DESCRIPTION

BREYANZI (lisocabtagene maraleucel) is a CD19-directed genetically modified autologous T cell immunotherapy administered as a defined composition of CAR-positive viable T cells (consisting of CD8 and CD4 components). The CAR is comprised of the 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. In addition, BREYANZI includes a nonfunctional truncated epidermal growth factor receptor (EGFRt) that is co-expressed on the cell surface with the CD19-specific CAR.

BREYANZI is a T cell product. BREYANZI is prepared from the patient’s T cells, which are obtained via a standard leukapheresis procedure. The purified CD8-positive and CD4-positive T cells are separately activated and transduced with the replication-incompetent lentiviral vector containing the anti-CD19 CAR transgene. The transduced T cells are expanded in cell culture, washed, formulated into a suspension, and cryopreserved as separate CD8 and CD4 component vials that together constitute a single dose of BREYANZI. The product must pass a sterility test before release for shipping as a frozen suspension in patient-specific vials. The product is thawed prior to administration [see Dosage and Administration (2.2) and How Supplied/Storage and Handling (16)].

The BREYANZI formulation contains 75% (v/v) Cryostor® CS10 [containing 7.5% dimethylsulfoxide (v/v)], 24% (v/v) Multiple Electrolytes for Injection, Type 1, 1% (v/v) of 25% albumin (human).

12 CLINICAL PHARMACOLOGY

12.1 Mechanism of Action

BREYANZI 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 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.

12.2 Pharmacodynamics

Following BREYANZI infusion, pharmacodynamic responses were evaluated over a 4-week period by measuring transient elevation of soluble biomarkers such as cytokines, chemokines, and other molecules. Peak elevation of soluble biomarkers was observed within the first 14 days after BREYANZI infusion and returned to baseline levels within 28 days.

B-cell aplasia, defined as CD19+ B cells comprising less than 3% of peripheral blood lymphocytes, is an on-target effect of BREYANZI. B-cell aplasia was observed in the majority of patients for up to 1 year following BREYANZI infusion.

12.3 Pharmacokinetics

Following infusion, BREYANZI exhibited an initial expansion followed by a bi-exponential decline.

Relapsed or Refractory LBCL

The median time of maximal expansion in peripheral blood occurred 10-12 days after infusion. BREYANZI was present in peripheral blood for an estimated median of 12.1 months (range: 0.1+ to 24.2+ months).

Among patients who received two or more prior lines of therapy for LBCL (TRANSCEND), responders (N=135) had a 2.3-fold higher median Cmax than nonresponders (N=37) (35,335 vs. 15,527 copies/µg). Responders had a 1.8-fold higher median AUC0-28d than nonresponders (273,552 vs. 155,240 day*copies/µg).

Patients < 65 years old (N=142) had a 3.1-fold and 2.3-fold higher median Cmax and AUC0-28d, respectively, compared to patients ≥ 65 years old (N=96). Sex, race, ethnicity, and body weight did not show clear relationships to Cmax and AUC0-28d.

Relapsed or Refractory CLL/SLL

The median time of maximal expansion in peripheral blood occurred 14 days after infusion. BREYANZI was present in peripheral blood for an estimated median of 12.0 months (range: 0.1+ to 30.1+ months).

Among patients who received prior therapy for CLL/SLL (TRANSCEND-CLL), responders (N=27) had a 2.0-fold higher median Cmax than nonresponders (N=25) (99,559 vs. 48,948 copies/µg). Responders had a 1.9-fold higher median AUC0-28d than nonresponders (793,893 vs. 408,307 day*copies/µg).

Relapsed or Refractory FL

The median time of maximal expansion in peripheral blood occurred 10 days after infusion. Median Cmax and AUC0-28d are 30,530 copies/µg and 253,400 day*copies/µg, respectively. BREYANZI was present in peripheral blood for an estimated median of 12.0 months (range: 0.3+ to 24.0+ months).

Relapsed or Refractory MCL

The median time of maximal expansion in peripheral blood occurred 10 days after infusion. Median Cmax and AUC0-28d were 30,968 copies/µg and 375,006 day*copies/µg, respectively. BREYANZI was present in peripheral blood for an estimated median of 17.9 months (range: 0.1+ to 24.2+ months).

Patients receiving medications for CRS and/or neurologic toxicities

In general, patients with higher CAR-T cell expansion tended to have higher rates of CRS and neurologic toxicities. Some patients required tocilizumab and/or corticosteroids for the management of CRS or neurologic toxicities [see Dosage and Administration (2.3)]. BREYANZI continued to expand and persist in patients who received tocilizumab and/or corticosteroids treatment. In TRANSCEND, patients treated with tocilizumab (N=49) had a 3.6-fold and 3.7-fold higher median Cmax and AUC0-28d of BREYANZI, respectively, compared to patients who did not receive tocilizumab (N=189). Similarly, patients who received corticosteroids (N=50) had a 3.8-fold and 3.7-fold higher median Cmax and AUC0‑28d of BREYANZI, respectively, compared to patients who did not receive corticosteroids (N=188).

12.6 Immunogenicity

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. Pre-existing anti-product antibodies were detected in 11% (28/261) in TRANSCEND, 1% (1/89) in TRANSFORM, 0% (0/51) in PILOT, 2% (2/86) in TRANSCEND-CLL, 2% (2/102) in TRANSCEND-FL, and 13% (11/87) in TRANSCEND-MCL Cohort of patients. Treatment-induced or treatment-boosted anti-product antibodies were detected in 11% (27/257) in TRANSCEND, 1% (1/89) in TRANSFORM, 2% (1/49) in PILOT, 7% (6/84) in TRANSCEND-CLL, 18% (18/100) in TRANSCEND-FL, and 18% (15/85) in TRANSCEND-MCL Cohort 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.

13 NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

No carcinogenicity or genotoxicity studies have been conducted with BREYANZI. No studies have been conducted to evaluate the effects of BREYANZI on fertility. In vitro studies with BREYANZI manufactured from healthy donors and patients showed no evidence for transformation and/or immortalization and no preferential integration near genes associated with oncogenic transformation.

14 CLINICAL STUDIES

14.1 Relapsed or Refractory Large B-Cell Lymphoma

Relapsed or Refractory LBCL After One Line of Therapy

TRANSFORM

A randomized, open-label, multicenter trial evaluated the efficacy of BREYANZI in adult patients with relapsed or refractory LBCL after first-line chemoimmunotherapy (TRANSFORM; NCT03575351). Patients had not yet received treatment for relapsed or refractory lymphoma, were potential candidates for autologous HSCT, and were required to have primary refractory disease or relapse within 12 months from complete response (CR) to initial chemoimmunotherapy. Eligibility criteria required adequate organ function and blood counts for HSCT.

In total, 184 patients were randomized in a 1:1 ratio to receive a single infusion of BREYANZI (planned dose, 100 × 106 CAR-positive viable T cells) or to receive standard therapy consisting of 3 cycles of chemoimmunotherapy followed by high-dose therapy and autologous HSCT in patients who attained CR or PR. All patients underwent leukapheresis prior to randomization.

Patients randomized to BREYANZI were to receive lymphodepleting chemotherapy consisting of fludarabine 30 mg/m2/day and cyclophosphamide 300 mg/m2/day concurrently for 3 days followed by BREYANZI infusion 2 to 7 days after completion of lymphodepleting chemotherapy. Bridging chemotherapy was permitted between leukapheresis and the start of lymphodepleting chemotherapy. BREYANZI was administered in the inpatient (79%) and outpatient (21%) setting.

In the overall study population, the median age was 59 years (range: 20 to 75 years), 57% were male, 59% were White, 10% were Asian, and 4% were Black. Diagnoses included de novo DLBCL NOS (55%), high-grade B-cell lymphoma (23%), primary mediastinal large B-cell lymphoma (10%), and DLBCL arising from indolent lymphoma (8%). Of these patients, 73% had primary refractory disease to last therapy and 27% had relapsed disease within 12 months of achieving CR to first-line therapy.

Of 92 patients randomized to receive BREYANZI, 89 (97%) received BREYANZI. The median time from leukapheresis to product availability was 26 days (range: 19 to 84 days), and the median time from leukapheresis to product infusion was 36 days (range: 25 to 91 days). Fifty-eight (63%) patients received bridging therapy. One patient received a nonconforming product (manufacturing failure; 1.1%).

Of the 92 patients randomized to receive standard therapy, 91 started treatment and 43 (47%) received high-dose therapy and HSCT. The most common reason for not receiving HSCT was lack of efficacy of the salvage chemotherapy.

The primary efficacy measure was event-free survival (EFS) as determined by an independent review committee (IRC). Other efficacy measures included progression-free survival. Efficacy is summarized in Table 16 and Figure 1. The estimated 1-year EFS was 45% [95% CI: 29, 59] in the BREYANZI arm and 24% [95% CI: 14, 35] in the standard therapy arm.

Of the 92 patients in the BREYANZI arm, the estimated median duration of response (DOR) was not reached (95% CI: 7.9 months, NR) in patients who achieved CR (N=61) and 2.3 months (95% CI: 2.1, NR) in patients who achieved a best response of PR (N=18).

An interim analysis of overall survival was conducted at the time of the primary EFS analysis. The interim analysis of overall survival did not meet the criteria for statistical significance. Forty-six patients randomized to the standard therapy arm (50%) subsequently received BREYANZI on protocol.

PILOT

The efficacy of BREYANZI was evaluated in a single-arm, open-label, multicenter trial (PILOT; NCT03483103) in transplant-ineligible patients with relapsed or refractory LBCL after one line of chemoimmunotherapy. The study enrolled patients who were not eligible for high-dose therapy and autologous HSCT due to organ function or age, while also having adequate organ function for CAR-T cell therapy. The study required at least one of the following criteria: age ≥ 70 years, adjusted diffusing capacity of the lung for carbon monoxide (DLCO) ≤ 60%; LVEF < 50%; creatinine clearance < 60mL/min; AST or ALT greater than 2 × ULN, or ECOG performance status of 2. The planned dose of BREYANZI was 100 × 106 CAR-positive viable T cells. Bridging therapy for disease control was permitted between leukapheresis and the start of lymphodepleting chemotherapy. Of the 61 patients treated with BREYANZI, 32 (53%) received bridging therapy.

BREYANZI was administered 2 to 7 days following completion of lymphodepleting chemotherapy. The lymphodepleting chemotherapy regimen consisted of fludarabine 30 mg/m2/day and cyclophosphamide 300 mg/m2/day concurrently for 3 days. BREYANZI was administered in the inpatient (67%) and outpatient (33%) setting.

Of 74 patients who underwent leukapheresis, 61 (82%) received BREYANZI and comprise the main efficacy population; 1 (1.4%) received CAR-positive T cells that did not meet the product specifications for BREYANZI (manufacturing failure); and 12 (16%) did not receive CAR-positive T cells for other reasons.

Of the 61 patients who received BREYANZI, the median age was 74 years (range: 53 to 84 years), 61% were male, 89% were White, 3% were Asian, and 2% were Black. Diagnoses included de novo DLBCL NOS (51%), high-grade B-cell lymphoma (33%), and DLBCL arising from follicular lymphoma (15%). Of these patients, 53% had primary refractory disease, 23% had relapse within 12 months of completing first-line therapy, and 25% had relapse >12 months after first-line therapy.

Efficacy was based on CR rate and DOR, as determined by an independent review committee (IRC) using 2014 Lugano criteria (Tables 17 and 18). The median time to CR was 1 month (range 0.8 to 6.9 months).

Relapsed or Refractory LBCL After Two or More Lines of Therapy

TRANSCEND

The efficacy of BREYANZI was evaluated in an open-label, multicenter, single-arm trial (TRANSCEND; NCT02631044) in adult patients with relapsed or refractory large B-cell non-Hodgkin lymphoma after at least 2 lines of therapy. The study included patients with ECOG performance status ≤ 2, prior autologous and/or allogeneic HSCT, and secondary CNS lymphoma involvement. The study excluded patients with a creatinine clearance of less than 30 mL/min, ALT > 5 times the ULN, or LVEF < 40%. There was no prespecified threshold for blood counts; patients were eligible to enroll if they were assessed by the investigator to have adequate bone marrow function to receive lymphodepleting chemotherapy. Bridging therapy for disease control was permitted between apheresis and the start of lymphodepleting chemotherapy, including intrathecal chemotherapy or radiation therapy for treatment of CNS involvement with lymphoma.

BREYANZI was administered 2 to 7 days following completion of lymphodepleting chemotherapy. The lymphodepleting chemotherapy regimen consisted of fludarabine 30 mg/m2/day and cyclophosphamide 300 mg/m2/day concurrently for 3 days. BREYANZI was administered in the inpatient and outpatient setting.

Of 299 patients who underwent leukapheresis for whom BREYANZI was manufactured in the dose range of 50 to 110 × 106 CAR-positive viable T cells:

Of the 192 patients in the main efficacy population, the median age was 63 years (range: 18 to 86 years), 69% were male, 84% were White, 6% were Black, and 4.7% were Asian. The median number of prior therapies was 3 (range: 1 to 8). Diagnoses were de novo DLBCL (53%), DLBCL transformed from indolent lymphoma (25%), high-grade B-cell lymphoma (14%), primary mediastinal large B-cell lymphoma (7%), follicular lymphoma, grade 3B (1.0%). Of these patients, 64% had disease refractory to last therapy, 53% had primary refractory disease, 37% had prior HSCT and 2.6% had CNS involvement.

Efficacy was based on CR rate and DOR, as determined by an IRC using 2014 Lugano criteria (Tables 19 and 20). The median time to first response (CR or partial response [PR]) was 1.0 month (range: 0.7 to 8.9 months). The median time to first CR was 1.0 month (range 0.8 to 12.5 months). Of the 104 patients who achieved CR, 23 initially had stable disease (6 patients) or PR (17 patients), with a median time to improvement of 2.2 months (range: 0.7 to 11.6 months).

Response durations were longer in patients who achieved a CR, as compared to patients with a best response of PR (Table 20). Of the 104 patients who achieved CR, 68 (65%) had remission lasting at least 6 months and 64 (62%) had remission lasting at least 9 months.

Of the 287 patients who underwent leukapheresis and had radiographically evaluable disease, 27 additional patients achieved a response, apart from the responses noted in Table 19. The IRC-assessed overall response rate in the leukapheresed population (n=287) was 59% (95% CI: 53, 64), with a CR rate of 43% (95% CI: 37, 49) and PR rate of 15% (95% CI: 11, 20). These efficacy results include responses that may have been contributed solely by bridging therapy, responses after receipt of product outside of the intended dose range, and responses to product that did not meet release specifications.

• •44 (15%) did not receive CAR-positive T cells either due to manufacturing failures (n=2), death (n=29), disease complications (n=6), or other reasons (n=7).
• •204 (68%) received BREYANZI in the intended dose range, of whom 192 were evaluable for efficacy (main efficacy population); 12 were not evaluable due to absence of PET positive disease at study baseline or after bridging therapy.
• •51 (17%) either received BREYANZI outside of the intended dose range (n=26) or received CAR-positive T cells that did not meet the product specifications for BREYANZI (manufacturing failures; n=25).

14.2 Relapsed or Refractory Chronic Lymphocytic Lymphoma or Small Lymphocytic Lymphoma

TRANSCEND-CLL

The efficacy of BREYANZI was evaluated in a phase 1/2, open-label, multicenter, single-arm trial (TRANSCEND-CLL; NCT03331198) in adult patients with R/R CLL or SLL who had received at least 2 prior lines of therapy including a BTK inhibitor and a BCL-2 inhibitor. Patients with del(17p), complex karyotype, and unmutated immunoglobulin heavy chain variable region (IGHV) were included in the study. The study enrolled patients with ECOG performance status of ≤ 1. The study excluded patients with a creatinine clearance of less than 30 mL/min, ALT > 5 times the ULN (except for subjects with leukemic infiltration of the liver), or LVEF < 40%. There was no prespecified threshold for blood counts; patients were eligible to enroll if they were assessed by the investigator to have adequate bone marrow function to receive lymphodepleting chemotherapy. The planned dose of BREYANZI was 100 × 106 CAR-positive viable T cells. Bridging therapy for disease control was permitted between apheresis and the start of lymphodepleting chemotherapy.

Of the 89 patients, BREYANZI was administered 2 to 11 days following completion of lymphodepleting chemotherapy. The lymphodepleting chemotherapy regimen consisted of fludarabine 30 mg/m2/day and cyclophosphamide 300 mg/m2/day concurrently for 3 days. BREYANZI was administered in the inpatient (88%) and outpatient (12%) settings.

Of 113 patients who underwent leukapheresis, 94 received BREYANZI. Of the 94, 84 received BREYANZI at 90 to 111 × 106 CAR-positive T cells and 10 received a cell-dose outside of this dose range; 3 received CAR-positive T cells that did not meet the product specifications for BREYANZI (manufacturing failure); and 16 other patients did not receive BREYANZI for other reasons.

The median time from leukapheresis to product availability was 24 days (range: 19 to 84 days), and the median time from leukapheresis to product infusion was 36 days (range: 28 to 384 days). Of the 89 patients treated with BREYANZI, 69 (78%) received bridging therapy.

Patients had measurable disease present before BREYANZI administration based on IRC assessment. Nineteen of 84 patients were not evaluable for efficacy (13 patients did not have baseline disease assessments performed after completion of bridging therapy, 1 patient lacked measurable disease, and 5 had Richter’s transformation). Of the 65 efficacy-evaluable patients, the median age was 66 years (range: 49 to 82 years), 68% were male, 80% were White, 3% were Black, 1% were Asian. Two‑percent were Hispanic and 89% were non-Hispanic. Eighty-three percent of patients had at least one high risk genetic attribute including 43% del(17p), 45% TP53 mutation, 45% unmutated IGHV, and 62% with complex karyotype. Fifty-one percent of the patients had bulky disease. The median number of prior therapies was 5 (range: 2 to 12). All 65 patients were exposed to a BTK inhibitor, of which 88% were refractory, 1.5% were relapsed, and 11% were intolerant. Of 65 patients who received a BCL-2 inhibitor, 92% were refractory, none relapsed, and 6% were intolerant. A total of 83% had disease refractory to last therapy.

Efficacy was based on ORR (including CR and PR) and DOR as determined by an IRC using 2018 International Workshop CLL (iwCLL) criteria (Tables 21 and 22). The median time to first response (CR or PR) was 1.1 months (range: 0.8 to 17.4 months). The median time to first CR was 3.0 months (range 1.1 to 17.9 months).

Minimal residual disease (MRD) negative status was defined as less than one CLL cell per 104 leukocytes using ClonoSEQ, a next generation sequencing assay (NGS) at any time post infusion (MRD‑negativity rate). There was no statistical testing of MRD-negativity rate. In patients who achieved CR, the MRD-negativity rate was 100% (13/13, 95% CI: 75.3, 100) in peripheral blood and 92.3% (12/13, 95% CI: 64, 99.8) in the bone marrow.

14.3 Relapsed or Refractory Follicular Lymphoma

TRANSCEND-FL

The efficacy of BREYANZI was evaluated in a Phase 2, open-label, multicenter, single-arm trial (TRANSCEND‑FL; NCT04245839) in adult patients with relapsed or refractory FL after two or more lines of systemic therapy (including an anti-CD20 antibody and an alkylating agent). The study enrolled patients with ECOG performance status of ≤ 1. The study excluded patients with a creatinine clearance of ≤ 30 mL/min, ALT > 5 times the ULN, or LVEF < 40%. There was no prespecified threshold for blood counts; patients were eligible to enroll if they were assessed by the investigator to have adequate bone marrow function to receive lymphodepleting chemotherapy. The planned dose of BREYANZI was 100 × 106 CAR-positive viable T cells. Bridging therapy for disease control was permitted between apheresis and the start of lymphodepleting chemotherapy.

A single dose of BREYANZI was administered 2 to 7 days following completion of lymphodepleting chemotherapy. The lymphodepleting chemotherapy regimen consisted of fludarabine 30 mg/m2/day and cyclophosphamide 300 mg/m2/day concurrently for 3 days. Six percent of patients were treated with BREYANZI in outpatient setting.

Of 114 patients who underwent leukapheresis, 107 received BREYANZI and the median dose administered was 100.02 x 106 CAR-positive viable T-cells (range: 93.4 to 109.2 x 106 CAR-positive viable T cells).The primary efficacy analysis included 94 patients who had PET-positive disease at study baseline or confirmation of PET-positive disease after bridging therapy, received conforming product in intended dose range and had at least 9 months of follow up from the date of first response.

The median time from leukapheresis to product availability was 29 days (range: 20 to 55 days), and the median time from leukapheresis to product infusion was 50 days (range: 31 to 313 days). Of the 107 patients treated with BREYANZI, 40 (40%) received bridging therapy.

The median age was 63 years (range: 23 to 80 years), 62% were male, ECOG performance status was 0 in 63% and 1 in 37% of patients; 55% were White, 3% were Black, 9% were Asian; 5% were Hispanic and 69% were non-Hispanic. The median number of prior systemic therapies was 3 (range: 2 to 10), with 46% receiving 2 prior lines, 22% receiving 3 prior lines and 32% receiving ≥ 4 prior lines. Twenty percent had received rituximab with lenalidomide, 25% had received a PI3K inhibitor, and 29% of patients had prior autologous HSCT. Eighty-nine percentage patients had Stage III-IV disease at study entry, 29% had bulky disease, 64% had progression within 6 months of the most recent regimen, and 50% had progression within 24 months of initial diagnosis (POD24).

Efficacy was based on ORR, defined as the percentage of patients with a best overall response (BOR) of CR or PR after BREYANZI infusion and duration of response as determined by an IRC (Tables 23 and 24). The median time to first response (CR or PR) was 1.0 month (range: 0.6 to 3.3 months). The median time to first CR was 3.0 months (range 0.6 to 18.0 months).

14.4 Relapsed or Refractory Mantle Cell Lymphoma

TRANSCEND-MCL Cohort

The efficacy of BREYANZI was evaluated in an open-label, multicenter, single-arm trial (TRANSCEND-MCL Cohort; NCT02631044) in adult patients with relapsed or refractory MCL who had received at least two prior lines of therapy including a BTK inhibitor, an alkylating agent, and an anti-CD20 agent. The study included patients with ECOG performance status of ≤ 1, prior autologous and/or allogeneic HSCT, and secondary CNS lymphoma involvement. The study excluded patients with a creatinine clearance ≤ 30 mL/min, alanine aminotransferase > 5 times the upper limit of normal or left ventricular ejection fraction (LVEF) < 40%. There was no prespecified threshold for blood counts; patients were eligible to enroll if they were assessed by the investigator to have adequate bone marrow function to receive lymphodepleting chemotherapy. The planned dose of BREYANZI was 100 × 106 CAR-positive viable T cells. Bridging therapy for disease control was permitted between apheresis and the start of lymphodepleting chemotherapy.

BREYANZI was administered 2 to 7 days following completion of lymphodepleting chemotherapy. The lymphodepleting chemotherapy regimen consisted of fludarabine 30 mg/m2/day and cyclophosphamide 300 mg/m2/day concurrently for 3 days. BREYANZI was administered in the inpatient (85%) and outpatient (15%) setting.

Of 89 patients who underwent leukapheresis, 71 received BREYANZI and the median dose administered was 99.8 x 106 CAR-positive viable T cells (range: 90 to 103 x 106 CAR-positive viable T cells). The primary efficacy analysis included a total of 68 patients with MCL who received at least 2 prior lines of therapy including a BTK inhibitor, had PET-positive disease at study baseline or after bridging therapy, received conforming product in the intended dose range, and had at least 6 months of follow up from the date of first response.

The median time from leukapheresis to product availability was 24 days (range: 17 to 80 days), and the median time from leukapheresis to product infusion was 36 days (range: 28 to 489 days). Of the 68 patients in the main efficacy population, 44 (65%) received bridging therapy.

The median age was 69 years (range: 36 to 86 years); 75% were male, ECOG performance status was 0 in 57% and 1 in 43% of patients; 87% were White, 1.5% were Black, 6% were Asian; 6% were Hispanic and 91% were non-Hispanic. The median number of prior therapies was 3 (range: 2 to 11) and 32% had received prior HSCT. Twenty-nine percent of patients had blastoid morphology and 10% had CNS lymphoma involvement at baseline. Sixty-nine percent of patients had disease refractory to their last therapy for MCL, defined as best response of partial response (PR), stable disease (SD), or progressive disease (PD) to last systemic or HSCT treatment with curative intent. All 68 patients were exposed to BTK inhibitor, of which 56% were refractory, defined as any response to prior BTK inhibitor that was less than PR.

Efficacy was based on ORR, defined as the percentage of patients with BOR of either CR or PR after BREYANZI infusion, as determined by an IRC using 2014 Lugano classification. Other efficacy measures included complete response rate and DOR, as determined by IRC (Tables 25 and Table 26).

Both the median time to first response (CR or PR) and the median time to first CR were 1 month (range: 0.7 to 3 months).

16 HOW SUPPLIED/STORAGE AND HANDLING

BREYANZI consists of genetically modified autologous T cells, supplied in vials as separate frozen suspensions of each CD8 component (NDC 73153-901-08) and CD4 component (NDC 73153-902-04). Each CD8 or CD4 component is packed in a carton containing up to 4 vials, depending upon the concentration of the cryopreserved drug product CAR-positive viable T cells. The cartons for each CD8 component and CD4 component are in an outer carton (NDC 73153-900-01). BREYANZI is shipped directly to the cell lab or clinical pharmacy associated with the infusion center in the vapor phase of a liquid nitrogen shipper. A Release for Infusion (RFI) Certificate for each component and patient-specific syringe labels are affixed inside the shipper.

• •Confirm patient identity upon receipt.
• •Store vials in the vapor phase of liquid nitrogen (less than or equal to minus 130°C) in a temperature-monitored system.
• •Thaw BREYANZI prior to infusion [see Dosage and Administration (2.2)].

17 PATIENT COUNSELING INFORMATION

Advise the patient to read the FDA-approved patient labeling (Medication Guide).

Ensure that patients understand the risk (11%) of manufacturing failure. In case of a manufacturing failure, a second manufacturing of BREYANZI may be attempted. While the patient awaits the product, additional bridging therapy (not the lymphodepletion) may be necessary. This bridging therapy may be associated with adverse events during the pre-infusion period, which could delay or prevent the administration of BREYANZI.

Advise patients that they will be monitored daily for at least 7 days following the BREYANZI infusion at a REMS-certified healthcare facility and instruct patients to remain within 2 hours of a REMS-certified healthcare facility for at least 4 weeks following the infusion.

Prior to infusion, advise patients of the following risks:

Advise patients of the need to:

• •Cytokine Release Syndrome (CRS) – Signs and symptoms of CRS (fever, chills, hypotension, tachycardia, hypoxia, and fatigue). Counsel patients to seek immediate medical attention should signs or symptoms of CRS occur at any time [see Warnings and Precautions (5.1) and Adverse Reactions (6.1)].
• •Neurologic Toxicities – Signs or symptoms associated with neurologic events including encephalopathy, confusion, decreased consciousness, speech disorders, tremor, and seizures. Counsel patients to seek immediate medical attention should signs or symptoms of neurologic toxicity occur at any time [see Warnings and Precautions (5.2) and Adverse Reactions (6.1)].
• •Serious Infections – Signs or symptoms associated with infection [see Warnings and Precautions (5.5) and Adverse Reactions (6.1)].
• •Prolonged Cytopenias – Signs or symptoms associated with bone marrow suppression including neutropenia, anemia, thrombocytopenia, or febrile neutropenia [see Warnings and Precautions (5.6) and Adverse Reactions (6.1)].
• •Secondary Malignancies: Secondary malignancies, including T cell malignancies, have occurred [see Boxed Warning, Warnings and Precautions (5.8), Adverse Reactions (6.2)].
