Yescarta® CAR T-Cell Therapy Quadruples Median Event-Free Survival Duration Over Standard of Care in Second-Line Relapsed or Refractory Large B-Cell Lymphoma

Landmark ZUMA-7 Trial Is First and Largest Randomized CAR T Study and the Only Study to Present Two-Year Event-Free Survival Data

ZUMA-7 Patient-Reported Outcomes Analysis Shows Yescarta Significantly Improves Quality of Life With Patients Returning to Baseline Faster With CAR T-Cell Therapy Than Current Standard of Care

These Data Demonstrate Yescarta as Potential New Standard of Care if Approved By Regulators

Kite, a Gilead Company (Nasdaq: GILD), today announced results from the primary analysis of ZUMA-7, a global Phase 3 study evaluating Yescarta® (axicabtagene ciloleucel) as a one-time infusion, in a head-to-head study against standard of care (SOC) for adults with large B-cell lymphoma (LBCL) who relapsed or were refractory to first-line treatment. Yescarta was evaluated against the current SOC which is a multi-step process intended to culminate in a stem cell transplant. ZUMA-7 was initiated in 2017 and is the first and largest Phase 3 randomized study of any CAR T-cell therapy in the second-line setting, enrolling 359 patients in 77 centers around the world. ZUMA-7 is considered a landmark trial for being the only study to reach the clinically meaningful two-year follow-up milestone. The findings were featured in the American Society of Hematology (ASH) press briefing today at their 63rd ASH Annual Meeting & Exposition and in a simultaneous publication in the New England Journal of Medicine (NEJM). The data will also be presented in full at the ASH plenary session on Sunday, December 12 (Abstract #2).

ZUMA-7 Global Phase 3 Clinical Trial Sites (Graphic: Business Wire)

With a median follow-up of over two years, the study met the primary endpoint of event-free survival (EFS; hazard ratio 0.398; 95% CI: 0.308-0.514, P<0.0001). Yescarta demonstrated a 2.5 fold increase in patients who were alive at two years and did not require the need for additional cancer treatment or experienced cancer progression (40.5% vs. 16.3%) and a four-fold greater median EFS (8.3 mo. vs. 2.0 mo.) compared to SOC. These statistically significant and clinically meaningful results were not confounded by any bridging chemotherapy. Improvements in EFS with Yescarta were consistent across key patient subgroups, including the elderly (HR: 0.276 [95% CI: 0.164-0.465]), primary refractory disease (HR: 0.426 [95% CI: 0.319-0.570]), high-grade B-cell lymphoma including double-hit and triple-hit lymphoma (HGBL; HR: 0.285 [95% CI: 0.137-0.593]), and double expressor lymphoma (HR: 0.424 [95% CI: 0.268-0.671]).

“The majority of patients with relapsed/refractory LBCL do not achieve long-term remission with currently available treatments and as we saw in this trial, are often not able to complete the multi-step process that culminates in a transplant,” said Frederick L. Locke, MD, ZUMA-7 Lead Principal Investigator and Co-Leader of the Immuno-Oncology Program at Moffitt Cancer Center, Tampa, Florida. “The results of ZUMA-7 are remarkable and represent a paradigm shift in the way that we should treat patients with LBCL in the second-line setting.”

Globally, LBCL is the most common type of non-Hodgkin lymphoma (NHL). In the United States, more than 18,000 people are diagnosed with LBCL each year. About 30-40% of patients with LBCL will need second-line treatment as their cancer will either relapse (return) or become refractory (not respond) to initial treatment. SOC therapy with curative intent for this patient population is a multi-step process intended to lead to a stem cell transplant as definitive treatment. The process starts with chemoimmunotherapy, and if a patient responds and can tolerate further treatment, they move on to high-dose chemotherapy (HDT) followed by a stem cell transplant (ASCT). Unfortunately, many patients do not advance through this lengthy process for a variety of reasons including lack of response to second-line chemotherapy, treatment complications or further disease progression.

In ZUMA-7, nearly three times as many patients randomized to Yescarta ultimately received the definitive CAR T-cell therapy treatment (94%) versus those randomized to SOC (36%) who received HDT+ASCT. Among randomized patients, overall response (ORR) and complete response (CR) rates were also higher with Yescarta (ORR: 83% vs. 50%, odds ratio: 5.31 [95% CI: 3.1-8.9; P<0.0001]; CR rate: 65% vs. 32%). Median overall survival (OS), evaluated as a preplanned interim analysis, favored Yescarta compared to SOC (not reached vs. 35.1 months, respectively). The primary analysis of OS will occur at approximately 210 deaths.

In a separate ZUMA-7 analysis of patient-reported outcomes (PROs) which will also be shared in an ASH oral presentation on December 12 (Abstract #430), patients receiving Yescarta and eligible for the PROs portion of the study (n=165) showed significant and clinically meaningful improvements in quality of life (QoL) at Day 100 compared with those who received SOC (n=131) using a prespecified analysis for three PRO domains (EORTC QLQ-C30 Physical Functioning, EORTC QLQ-C30 Global Health Status/QOL, and EQ-5D-5L visual analog scale [VAS]). The data also suggest faster recovery to pretreatment QoL for patients treated with Yescarta versus SOC.

“Beyond the poor prognosis, patients with relapsed or refractory LBCL also face substantially decreased quality of life with chemotherapy and stem cell transplant treatments,” said Mahmoud Elsawy, MD, MSc, ZUMA-7 Investigator and Medical Director of Immune Effector Cell Therapy Program at Queen Elizabeth II Health Sciences Centre and Assistant Professor at Dalhouse University, Halifax, NS, Canada. “With the primary results of ZUMA-7, we see that axicabtagene ciloleucel offers superior clinical outcomes, and with the PRO analysis we also have support that it provides a better quality of life for these patients. Giving patients not just more but also better quality time is always our goal.”

In the ZUMA-7 trial, Yescarta had a manageable safety profile that was consistent with previous studies. Among the 170 Yescarta-treated patients evaluable for safety, Grade ≥3 cytokine release syndrome (CRS) and neurologic events were observed in 6% and 21% of patients, respectively. No Grade 5 CRS or neurologic events occurred. In the SOC arm, 83% of patients had high grade events, mostly cytopenias (low blood counts).

Global regulatory filings to expand the indication for Yescarta to include second-line relapsed or refractory LBCL based on the ZUMA-7 data are currently underway. The U.S. Food and Drug Administration (FDA) has accepted the supplemental Biologics License Application (sBLA) and granted Priority Review designation to Yescarta for this patient population with a target action date under the Prescription Drug User Fee Act (PDUFA) of April 1, 2022. Regulatory submissions have also been filed with other global health authorities, including the European Medicines Agency (EMA).

“The ZUMA-7 trial demonstrates the power of CAR T-cell therapy when used earlier in the course of treatment and for the first time shows the promise of CAR T to replace a standard of care that has been in place for decades,” said Frank Neumann, MD, PhD, Kite’s Global Head of Clinical Development. “Kite is the world’s leading company dedicated exclusively to cell therapy, and we are committed to continuing to conduct groundbreaking research like the ZUMA-7 study to bring the hope of survival to more patients through this technology.”

About ZUMA-7 Study Design

ZUMA-7 is a randomized, open-label, global, multicenter, Phase 3 study evaluating the safety and efficacy of Yescarta versus current standard of care (SOC) for second-line therapy (platinum-based salvage combination chemoimmunotherapy regimen followed by high-dose therapy [HDT] and autologous stem cell transplant [ASCT] in those who respond to salvage chemotherapy) in adult patients with relapsed or refractory LBCL within 12 months of first-line therapy. In the study, 359 patients in 77 centers around the world were randomized (1:1) to receive a single infusion of Yescarta or current SOC second-line therapy. The primary endpoint is event free survival (EFS) as determined by blinded central review, and defined as the time from randomization to the earliest date of disease progression per Lugano Classification, commencement of new lymphoma therapy, or death from any cause. Key secondary endpoints include objective response rate (ORR) and overall survival (OS). Additional secondary endpoints include patient reported outcomes (PROs) and safety.

About Yescarta

Please see full Prescribing Information, including BOXED WARNING and Medication Guide.

Yescarta is a CD19-directed genetically modified autologous T cell immunotherapy currently indicated for the treatment of:

  • Adult patients with relapsed or refractory large B-cell lymphoma after two or more lines of systemic therapy, including diffuse large B-cell lymphoma (DLBCL) not otherwise specified, primary mediastinal large B-cell lymphoma, high grade B-cell lymphoma, and DLBCL arising from follicular lymphoma.

    Limitations of Use: Yescarta is not indicated for the treatment of patients with primary central nervous system lymphoma.
  • Adult patients with relapsed or refractory follicular lymphoma (FL) after two or more lines of systemic therapy. This indication is approved under accelerated approval based on response rate. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trial(s).



  • Cytokine Release Syndrome (CRS), including fatal or life-threatening reactions, occurred in patients receiving Yescarta. Do not administer Yescarta to patients with active infection or inflammatory disorders. Treat severe or life-threatening CRS with tocilizumab or tocilizumab and corticosteroids.
  • Neurologic toxicities, including fatal or life-threatening reactions, occurred in patients receiving Yescarta, including concurrently with CRS or after CRS resolution. Monitor for neurologic toxicities after treatment with Yescarta. Provide supportive care and/or corticosteroids as needed.
  • Yescarta is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the Yescarta and Tecartus REMS Program.

CYTOKINE RELEASE SYNDROME (CRS), including fatal or life-threatening reactions, occurred. CRS occurred in 88% (224/254) of all patients with non-Hodgkin lymphoma (NHL), including Grade ≥3 in 10%. CRS occurred in 94% (101/108) of patients with large B-cell lymphoma (LBCL), including Grade ≥3 in 13%. Among patients with LBCL who died after receiving Yescarta, 4 had ongoing CRS events at the time of death. The median time to onset of CRS was 2 days (range: 1-12 days) and the median duration was 7 days (range: 2-58 days) for patients with LBCL. CRS occurred in 84% (123/146) of patients with indolent non-Hodgkin lymphoma (iNHL), including Grade ≥3 in 8% (11/146). Among patients with iNHL who died after receiving Yescarta, 1 patient had an ongoing CRS event at the time of death. The median time to onset of CRS was 4 days (range: 1-20 days) and median duration was 6 days (range: 1-27 days) for patients with iNHL. Key manifestations of CRS (≥10%) in all patients combined included fever (80%), hypotension (38%), tachycardia (29%), hypoxia (21%), chills (21%), and headache (13%). Serious events that may be associated with CRS include cardiac arrhythmias (including atrial fibrillation and ventricular tachycardia), cardiac arrest, cardiac failure, renal insufficiency, capillary leak syndrome, hypotension, hypoxia, multi-organ failure and hemophagocytic lymphohistiocytosis/macrophage activation syndrome. In a subsequent cohort of LBCL patients, tocilizumab and/or corticosteroids were administered for ongoing Grade 1 events. CRS occurred in 93% (38/41) of these patients and 2% (1/41) had Grade 3 CRS, with no patients experiencing a Grade 4 or 5 event. The median time to onset of CRS was 2 days (range: 1 to 8 days) and the median duration of CRS was 7 days (range: 2 to 16 days). Key manifestations of CRS (>5%) included pyrexia, hypotension, chills, headache, nausea, tachycardia, C-reactive protein increased, fatigue, hypoxia, and vomiting. Ensure that 2 doses of tocilizumab are available prior to Yescarta infusion. Following infusion, monitor patients for signs and symptoms of CRS at least daily for 7 days at the certified healthcare facility, and for 4 weeks thereafter. Counsel patients to seek immediate medical attention should signs or symptoms of CRS occur at any time. At the first sign of CRS, institute treatment with supportive care, tocilizumab, or tocilizumab and corticosteroids as indicated.

NEUROLOGIC TOXICITIES that were fatal or life-threatening occurred. Neurologic toxicities occurred in 81% (206/254) of all patients with NHL receiving Yescarta, including Grade ≥3 in 26%. Neurologic toxicities occurred in 87% (94/108) of patients with LBCL, including Grade ≥3 in 31%. The median time to onset was 4 days (range: 1-43 days) and the median duration was 17 days for patients with LBCL. Neurologic toxicities occurred in 77% (112/146) of patients with iNHL, including Grade ≥3 in 21%. The median time to onset was 6 days (range: 1-79 days) and the median duration was 16 days for patients with iNHL. 98% of all neurologic toxicities in patients with LBCL and 99% of all neurologic toxicities in patients with iNHL occurred within the first 8 weeks of Yescarta infusion. Neurologic toxicities occurred within the first 7 days of infusion for 89% of affected patients with LBCL and 74% of affected patients with iNHL. The most common neurologic toxicities (≥10%) in all patients combined included encephalopathy (53%), headache (45%), tremor (31%), dizziness (20%), delirium (16%), aphasia (15%), and insomnia (11%). Prolonged encephalopathy lasting up to 173 days was noted. Serious events, including leukoencephalopathy and seizures, as well as fatal and serious cases of cerebral edema, have occurred. In a subsequent cohort of LBCL patients who received corticosteroids at the onset of Grade 1 toxicities, neurologic toxicities occurred in 78% (32/41) of these patients and 20% (8/41) had Grade 3 neurologic toxicities with no patients experiencing a Grade 4 or 5 event. The median time to onset of neurologic toxicities was 6 days (range: 1-93 days) with a median duration of 8 days (range: 1-144 days). The most common neurologic toxicities were consistent with the overall LBCL population treated with Yescarta. Following Yescarta infusion, monitor patients for signs and symptoms of neurologic toxicities at least daily for 7 days at the certified healthcare facility, and for 4 weeks thereafter, and treat promptly.

REMS: Because of the risk of CRS and neurologic toxicities, Yescarta is available only through a restricted program called the Yescarta and Tecartus REMS Program which requires that: Healthcare facilities that dispense and administer Yescarta must be enrolled and comply with the REMS requirements and must have on-site, immediate access to a minimum of 2 doses of tocilizumab for each patient for infusion within 2 hours after Yescarta infusion, if needed for treatment of CRS. Certified healthcare facilities must ensure that healthcare providers who prescribe, dispense, or administer Yescarta are trained about the management of CRS and neurologic toxicities. Further information is available at or 1-844-454-KITE (5483).

HYPERSENSITIVITY REACTIONS: Allergic reactions, including serious hypersensitivity reactions or anaphylaxis, may occur with the infusion of Yescarta.

SERIOUS INFECTIONS: Severe or life-threatening infections occurred. Infections (all grades) occurred in 47% (119/254) of all patients with NHL. Grade ≥3 infections occurred in 19% of patients, Grade ≥3 infections with an unspecified pathogen occurred in 15%, bacterial infections in 5%, viral infections in 2%, and fungal infections in 1%. Yescarta should not be administered to patients with clinically significant active systemic infections. Monitor patients for signs and symptoms of infection before and after infusion and treat appropriately. Administer prophylactic anti-microbials according to local guidelines. Febrile neutropenia was observed in 40% of all patients with NHL and 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. In immunosuppressed patients, including those who have received Yescarta, life-threatening and fatal opportunistic infections including disseminated fungal infections (e.g., candida sepsis and aspergillus infections) and viral reactivation (e.g., human herpes virus-6 [HHV-6] encephalitis and JC virus progressive multifocal leukoencephalopathy [PML]) have been reported. The possibility of HHV-6 encephalitis and PML should be considered in immunosuppressed patients with neurologic events and appropriate diagnostic evaluations should be performed. 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. Perform screening for HBV, HCV, and HIV in accordance with clinical guidelines before collection of cells for manufacturing.

PROLONGED CYTOPENIAS: Patients may exhibit cytopenias for several weeks following lymphodepleting chemotherapy and Yescarta infusion. Grade ≥3 cytopenias not resolved by Day 30 following Yescarta infusion occurred in 30% of all patients with NHL and included neutropenia (22%), thrombocytopenia (13%), and anemia (5%). Monitor blood counts after infusion.

HYPOGAMMAGLOBULINEMIA and B-cell aplasia can occur. Hypogammaglobulinemia occurred in 17% of all patients with NHL. Monitor immunoglobulin levels after treatment and manage using infection precautions, antibiotic prophylaxis, and immunoglobulin replacement. The safety of immunization with live viral vaccines during or following Yescarta 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 Yescarta treatment, and until immune recovery following treatment.

SECONDARY MALIGNANCIES may develop. Monitor life-long for secondary malignancies. In the event that one occurs, contact Kite at 1-844-454-KITE (5483) to obtain instructions on patient samples to collect for testing.

EFFECTS ON ABILITY TO DRIVE AND USE MACHINES: Due to the potential for neurologic events, including altered mental status or seizures, patients are at risk for altered or decreased consciousness or coordination in the 8 weeks following Yescarta infusion. Advise patients to refrain from driving and engaging in hazardous occupations or activities, such as operating heavy or potentially dangerous machinery, during this initial period.

ADVERSE REACTIONS: The most common adverse reactions (incidence ≥20%) in patients with LBCL included CRS, fever, hypotension, encephalopathy, tachycardia, fatigue, headache, decreased appetite, chills, diarrhea, febrile neutropenia, infections with pathogen unspecified, nausea, hypoxia, tremor, cough, vomiting, dizziness, constipation, and cardiac arrhythmias. The most common non-laboratory adverse reactions (incidence ≥20%) in patients with iNHL included fever, CRS, hypotension, encephalopathy, fatigue, headache, infections with pathogen unspecified, tachycardia, febrile neutropenia, musculoskeletal pain, nausea, tremor, chills, diarrhea, constipation, decreased appetite, cough, vomiting, hypoxia, arrhythmia, and dizziness.
