Rhea-AI Summary

Kite, a Gilead Company (Nasdaq: GILD) Announces FDA Approval for Yescarta Label Update Demonstrating Superior Overall Survival in Patients with Relapsed/Refractory Large B-cell Lymphoma

Insights

Medical Research Analyst

The FDA's approval of a label update for Yescarta, based on the ZUMA-7 study's findings, represents a significant advancement in the treatment of relapsed or refractory large B-cell lymphoma (R/R LBCL). This update is not merely incremental; it reflects a 27.4% reduction in the risk of death compared to the standard of care (SOC), which is a substantial improvement in overall survival (OS) rates. The 39-month OS rates show a relative 38% improvement for patients treated with Yescarta.

From a medical standpoint, the transition from a multi-step SOC that culminates in autologous stem cell transplant (ASCT) to a single infusion of Yescarta simplifies the treatment regimen. This is particularly noteworthy given that less than 40% of patients typically complete the SOC process, while 94% of patients randomized to Yescarta in the study received treatment. This could lead to a paradigm shift in the second-line treatment of R/R LBCL, potentially establishing Yescarta as the new SOC.

The label update not only has the potential to affect patient outcomes but also carries implications for Kite's business performance. The enhanced efficacy of Yescarta could lead to increased adoption and market share, potentially impacting Gilead's revenue and positioning in the oncology market. Investors and stakeholders should monitor adoption rates and payer coverage decisions as indicators of the drug's commercial success.

Oncology Doctor

Yescarta's label expansion to include overall survival data is a milestone in oncology, particularly for R/R LBCL, where treatment options have been limited. The statistically significant improvement in OS is clinically meaningful, as it suggests a higher likelihood of long-term remission for patients. The fact that over half of the SOC arm received cell therapy off protocol and Yescarta still demonstrated superior outcomes is noteworthy.

Understanding the clinical context, autologous stem cell transplant has been a cornerstone in the treatment of aggressive lymphomas, but its complexity and the physical toll it takes on patients mean that many are unable to complete the treatment. Yescarta's one-time infusion offers a less invasive and potentially more accessible treatment option, which could lead to better patient adherence and outcomes.

For healthcare providers, the updated label reinforces confidence in prescribing Yescarta as a second-line therapy. However, the cost of treatment, insurance coverage and the need for specialized centers capable of administering CAR T-cell therapies like Yescarta are factors that could affect its widespread adoption.

Healthcare Industry Analyst

With the European Medicines Agency's recent approval of the Summary of Product Characteristics (SmPC) update and the FDA's label update for Yescarta, there is a clear indication of regulatory confidence in the treatment's efficacy. The landmark Phase 3 ZUMA-7 study serves as a robust foundation for these updates and may influence oncology treatment guidelines globally.

The business implications for Kite, a Gilead Company, are substantial. As the first and only treatment to demonstrate such a survival benefit in nearly three decades, Yescarta has the potential to capture a significant share of the R/R LBCL treatment market. The competitive landscape will likely respond, with other companies either seeking to develop competing therapies or potentially entering into partnerships or licensing agreements with Kite.

Investors should consider the long-term growth potential of Yescarta, factoring in the addressable patient population, pricing strategies and the potential for expansion into additional indications. The cost-effectiveness of the therapy, in comparison to the traditional multi-step treatment process, may also become a focal point in discussions with payers and healthcare providers.

-- Yescarta is the First and Only Treatment in Nearly 30 Years to Demonstrate Superior Overall Survival for Patients with Relapsed/Refractory Large B-cell Lymphoma Versus Standard of Care as Second-Line Treatment With Curative Intent* --

SANTA MONICA, Calif.--(BUSINESS WIRE)-- Kite, a Gilead Company (Nasdaq: GILD), today announced that the U.S. Food and Drug Administration (FDA) has approved a label update for Yescarta^® (axicabtagene ciloleucel) to include the overall survival (OS) primary analysis from the landmark Phase 3 ZUMA-7 study showing a statistically significant improvement for Yescarta in OS versus standard of care (SOC) as second-line treatment with curative intent for patients with relapsed or refractory large B-cell lymphoma (R/R LBCL) within 12 months of completion of first-line therapy.

The label update is based on results from the ZUMA-7 study which demonstrated a 27.4% reduction in the risk of death with Yescarta versus SOC, a relative 38% improvement in OS. With an estimated median follow up of 46.7 months overall, the primary analysis of OS showed a statistically significant improvement in the Yescarta arm compared to the standard therapy arm, despite more than half of patients (57%) in the SOC arm subsequently receiving cell therapy off protocol. The estimated 39-month OS rates were 55.9% in the Yescarta arm and 46% in the SOC arm.

“This U.S. label update for Yescarta is an important step to reinforce healthcare provider confidence to treat eligible patients with Yescarta, immediately following progression or relapse in large B-cell lymphoma,” said Frank Neumann, MD, PhD, Senior Vice President and Global Head of Clinical Development, Kite. “Our ZUMA-7 overall survival analysis proves that when given as second-line therapy, Yescarta is even more effective in improving patient survival than standard of care treatment. Coupled with our rapid and reliable manufacturing, it is our hope to provide patients a chance to live longer lives.”

SOC therapy for this patient population has historically been a multi-step process expected to end with stem-cell transplant. 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 autologous stem cell transplant (ASCT). Despite this being the prior SOC, less than 40% of patients who started this multi-step process made it through to complete stem cell transplant, compared with 94% of patients randomized to Yescarta in the ZUMA-7 study who received a one-time Yescarta infusion.

Underscoring the Significance for Patients

As the first and only treatment in nearly 30 years to improve survival for patients with R/R LBCL in this setting, Yescarta can potentially change the standard of care for these patients who previously had limited options for long-term remission.

“Lymphoma Research Foundation has continuously supported efforts for the development of new treatments in large B-cell lymphoma with the shared goal of finding a cure,” said Meghan Gutierrez, Chief Executive Officer, Lymphoma Research Foundation. “We applaud Kite for bringing the oncology community one step closer to eradicating large B-cell lymphoma and offering new hope to patients.”

In November 2023, the European Medicines Agency approved an update to the Summary of Product Characteristics (SmPC) to include the ZUMA-7 overall survival analysis.

About ZUMA-7 Study

ZUMA-7 is a randomized, open-label, global, multicenter, Phase 3 study evaluating the safety and efficacy of Yescarta versus SOC for initial treatment of adult patients with R/R 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 prior SOC second-line treatment. The primary endpoint is 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 OS. Additional secondary endpoints include patient reported outcomes (PROs) and safety. Per hierarchical testing of primary and key secondary endpoints and group sequential testing of OS, an interim analysis of OS occurred at the time of the primary EFS analysis. The prespecified primary OS analysis was to be conducted after 210 deaths or no later than five years after the first patient was randomized.

Yescarta demonstrated a 2.5-fold increase in patients who were alive at two years and did not experience cancer progression or require the need for additional cancer treatment (40.5% vs. 16.3%) and a four-fold greater median EFS (8.3 mo. vs. 2.0 mo.) compared to SOC (hazard ratio 0.398; 95% CI: 0.308-0.514, P<0.0001). In addition to being the largest and longest study of its kind, ZUMA-7 study participants on the Yescarta arm did not receive additional bridging chemotherapy that could have potentially confounded results.

Nearly three times as many patients randomized to Yescarta ultimately received the definitive CAR T-cell therapy treatment (94%) versus those randomized to SOC (35%) who received on-protocol HDT+ASCT. More patients responded to Yescarta (ORR: 83% vs. 50%, odds ratio: 5.31 [95% CI: 3.1-8.9; P<0.0001) and achieved a complete response (CR) with Yescarta (CR rate: 65% vs. 32%) than with SOC. At the time of the primary EFS analysis, more than half of patients in the SOC arm subsequently received Yescarta off study.

In the study, Yescarta had a safety profile that was consistent with previous studies. Among the 168 Yescarta-treated patients evaluable for safety, Grade ≥3 cytokine release syndrome (CRS) and neurologic events were observed in 7% and 25% of patients, respectively. In the SOC arm, 83% of patients had high grade events, mostly cytopenias (low blood counts).

The Yescarta U.S. Prescribing Information has a BOXED WARNING for the risks of CRS and neurologic toxicities, and Yescarta is approved with a Risk Evaluation and Mitigation Strategy (REMS) due to these risks; see below for Important Safety Information.

About Large B-Cell Lymphoma (LBCL)

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.

U.S. IMPORTANT SAFETY INFORMATION

BOXED WARNING: CYTOKINE RELEASE SYNDROME AND NEUROLOGIC TOXICITIES

• 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)

CRS, including fatal or life-threatening reactions, occurred. CRS occurred in 90% (379/422) of patients with non-Hodgkin lymphoma (NHL), including ≥ Grade 3 in 9%. CRS occurred in 93% (256/276) of patients with large B-cell lymphoma (LBCL), including ≥ Grade 3 in 9%. Among patients with LBCL who died after receiving YESCARTA, 4 had ongoing CRS events at the time of death. For patients with LBCL in ZUMA-1, the median time to onset of CRS was 2 days following infusion (range: 1-12 days) and the median duration was 7 days (range: 2-58 days). For patients with LBCL in ZUMA-7, the median time to onset of CRS was 3 days following infusion (range: 1-10 days) and the median duration was 7 days (range: 2-43 days). CRS occurred in 84% (123/146) of patients with indolent non-Hodgkin lymphoma (iNHL) in ZUMA-5, including ≥ Grade 3 in 8%. 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 the median duration was 6 days (range: 1-27 days) for patients with iNHL.

Key manifestations of CRS (≥ 10%) in all patients combined included fever (85%), hypotension (40%), tachycardia (32%), chills (22%), hypoxia (20%), headache (15%), and fatigue (12%). Serious events that may be associated with CRS include cardiac arrhythmias (including atrial fibrillation and ventricular tachycardia), renal insufficiency, cardiac failure, respiratory failure, cardiac arrest, capillary leak syndrome, multi-organ failure, and hemophagocytic lymphohistiocytosis/macrophage activation syndrome.

The impact of tocilizumab and/or corticosteroids on the incidence and severity of CRS was assessed in 2 subsequent cohorts of LBCL patients in ZUMA-1. Among patients who received tocilizumab and/or corticosteroids for ongoing Grade 1 events, CRS occurred in 93% (38/41), including 2% (1/41) with Grade 3 CRS; no patients experienced a Grade 4 or 5 event. The median time to onset of CRS was 2 days (range: 1-8 days) and the median duration of CRS was 7 days (range: 2-16 days). Prophylactic treatment with corticosteroids was administered to a cohort of 39 patients for 3 days beginning on the day of infusion of YESCARTA. Thirty-one of the 39 patients (79%) developed CRS and were managed with tocilizumab and/or therapeutic doses of corticosteroids with no patients developing ≥ Grade 3 CRS. The median time to onset of CRS was 5 days (range: 1-15 days) and the median duration of CRS was 4 days (range: 1-10 days). Although there is no known mechanistic explanation, consider the risk and benefits of prophylactic corticosteroids in the context of pre-existing comorbidities for the individual patient and the potential for the risk of Grade 4 and prolonged neurologic toxicities.

Ensure that 2 doses of tocilizumab are available prior to YESCARTA 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

Neurologic toxicities (including immune effector cell-associated neurotoxicity syndrome) that were fatal or life-threatening occurred. Neurologic toxicities occurred in 78% (330/422) of all patients with NHL receiving YESCARTA, including ≥ Grade 3 in 25%. Neurologic toxicities occurred in 87% (94/108) of patients with LBCL in ZUMA-1, including ≥ Grade 3 in 31% and in 74% (124/168) of patients in ZUMA-7 including ≥ Grade 3 in 25%. The median time to onset was 4 days (range: 1-43 days) and the median duration was 17 days for patients with LBCL in ZUMA-1. The median time to onset for neurologic toxicity was 5 days (range:1- 133 days) and the median duration was 15 days in patients with LBCL in ZUMA-7. 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. Ninety-eight percent 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 87% of affected patients with LBCL and 74% of affected patients with iNHL.

The most common neurologic toxicities (≥ 10%) in all patients combined included encephalopathy (50%), headache (43%), tremor (29%), dizziness (21%), aphasia (17%), delirium (15%), and insomnia (10%). Prolonged encephalopathy lasting up to 173 days was noted. Serious events, including aphasia, leukoencephalopathy, dysarthria, lethargy, and seizures occurred. Fatal and serious cases of cerebral edema and encephalopathy, including late-onset encephalopathy, have occurred.

The impact of tocilizumab and/or corticosteroids on the incidence and severity of neurologic toxicities was assessed in 2 subsequent cohorts of LBCL patients in ZUMA-1. Among patients who received corticosteroids at the onset of Grade 1 toxicities, neurologic toxicities occurred in 78% (32/41), and 20% (8/41) had Grade 3 neurologic toxicities; no patients experienced 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). Prophylactic treatment with corticosteroids was administered to a cohort of 39 patients for 3 days beginning on the day of infusion of YESCARTA. Of those patients, 85% (33/39) developed neurologic toxicities, 8% (3/39) developed Grade 3, and 5% (2/39) developed Grade 4 neurologic toxicities. The median time to onset of neurologic toxicities was 6 days (range: 1-274 days) with a median duration of 12 days (range: 1-107 days). Prophylactic corticosteroids for management of CRS and neurologic toxicities may result in a higher grade of neurologic toxicities or prolongation of neurologic toxicities, delay the onset of and decrease the duration of CRS.

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 in the management of CRS and neurologic toxicities. Further information is available at www.YescartaTecartusREMS.com 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 45% of patients with NHL; ≥ Grade 3 infections occurred in 17% of patients, including ≥ Grade 3 infections with an unspecified pathogen in 12%, bacterial infections in 5%, viral infections in 3%, 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 antimicrobials according to local guidelines.

Febrile neutropenia was observed in 36% 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, including YESCARTA. 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 39% of all patients with NHL and included neutropenia (33%), thrombocytopenia (13%), and anemia (8%). Monitor blood counts after infusion.

HYPOGAMMAGLOBULINEMIA

B-cell aplasia and hypogammaglobulinemia can occur. Hypogammaglobulinemia was reported as an adverse reaction in 14% 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

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 non-laboratory adverse reactions (incidence ≥ 20%) in patients with LBCL in ZUMA-7 included fever, CRS, fatigue, hypotension, encephalopathy, tachycardia, diarrhea, headache, musculoskeletal pain, nausea, febrile neutropenia, chills, cough, infection with an unspecified pathogen, dizziness, tremor, decreased appetite, edema, hypoxia, abdominal pain, aphasia, constipation, and vomiting.
