The key clinical highlights of LBL-034

Safe escalation to 1200 μg/kg with no DLTs or MTD reached.
Adverse events impacting quality of life were predominantly Grade 1–2 and occurred mainly during Cycle 1, with markedly lower incidence thereafter. Taste, skin, and nail toxicities were infrequent and generally self-resolving.
Strong efficacy across dose levels 400–1200 μg/kg (n=40).
ORR reached 82.5%, with ≥CR at 52.5%, ≥VGPR at 72.5%, and MRD negativity at 80.0%.
At 800 μg/kg, ORR and ≥CR were 90.9% and 63.6%, respectively.
Robust activity in difficult-to-treat RRMM subgroups.
Extramedullary disease (EMD): ORR 75.0%, including two sCRs. At 1200 μg/kg, ORR in EMD patients reached 100%, with rapid EMD lesion regression observed.
Prior BCMA-treated patients: ORR 85.7%, with CR/sCR 57.1%.
Durable clinical benefit.
Across the 400–1200 μg/kg range, the 12-month PFS rate was 61.2% (median follow-up: 9.6 months). At 400 μg/kg (n=11), median follow-up reached 13.1 months, with a 12-month PFS rate of 56.8%.
Executive Commentary

Dr. Charles Cai, Chief Medical Officer of Leads Biolabs, stated:

"We are delighted that the strong efficacy and clinical potential of LBL-034 have been recognized by the international scientific community. A Phase II trial evaluating the safety and efficacy of LBL-034 with a RP2D at 1200 μg/kg in 4 populations, including 4L+RRMM, 2L+RRMM with EMD, 4L+RRMM with prior BCMA therapy, and R/R Plasma Cell Leukopenia (PCL) is currently ongoing. With our focused and efficient clinical development strategy, we aim to deliver new treatment options to patients with multiple myeloma, particularly those who are refractory or have extramedullary disease, as quickly as possible."

About LBL-034

LBL-034 is a bispecific T-cell engager (TCE) that targets both GPRC5D and CD3, developed using the Company’s proprietary LeadsBody platform. Designed with a 2:1 binding format—two sites for GPRC5D and one for CD3—LBL-034 can selectively target GPRC5D+ cancer cells, conditionally activate T cells, reduce the risk of cytokine release, minimize the risk of systemic toxicity, and lower the risk of T cell exhaustion, thereby exerting anti-tumor effects in an efficient, low-toxic, and long-term stable manner.

In preclinical studies, LBL-034 has demonstrated strong efficacy signals, comparable to or exceeding those of leading competitors. The molecule is currently being evaluated in a Phase I/II clinical trial for relapsed or refractory multiple myeloma (RRMM) in China. According to Frost & Sullivan, as of November 2024, LBL-034 is the second most clinically advanced GPRC5D-targeted CD3 T-cell engager globally. In October 2024, LBL-034 received Orphan Drug Designation (ODD) from the U.S. FDA for the treatment of multiple myeloma.

The ASH (Free ASH Whitepaper) 2025 dataset builds on the promising efficacy signals previously shared at ASCO (Free ASCO Whitepaper) [2] 2025, highlighting rapid, deep, and durable responses with a favorable safety profile and encouraging early overall survival. Notably, responses were strongest at the 10mg ICT01 dose, which has now been endorsed by the FDA for further development. In 2025, ICT01 also received Orphan Drug Designation from both the FDA[3] and EMA.

"ICT01 continues to demonstrate rapid and durable responses across AML subtypes. The updated ASH (Free ASH Whitepaper) data further strengthens our confidence in ICT01’s ability, when added to Aza-Ven, to deliver deep, lasting remissions that have the potential to translate into meaningful overall survival improvement for patients" said Stephan Braun, MD, PhD, Chief Medical Officer of ImCheck Therapeutics. "We see an early onset of complete remissions, consistently strong efficacy at the selected dose across molecular subtypes, and signs of durable responses even in adverse-risk patients. These findings together with the encouraging early survival signal create a compelling case as we advance toward late-stage development."

Key Highlights:
Patient population: At the data cut-off on October 6, 2025, 57 patients aged 51 to 87 had been enrolled. Of these, 41 received 10 mg ICT01 and 16 received 75 mg ICT01, each in combination with Aza-Ven.
Rapid responses: More than 90% of patients treated with ICT01 (10 mg) achieved CRc4 as their best response already by end of Cycle 2.
Broad molecular activity: The 10 mg dose selected for future studies produced higher CR/CRc rates across molecular subtypes, including favorable-, intermediate-, and adverse-risk AML (e.g., TP53-mutated) versus the 75 mg dose.
Durability emerging: At a median follow-up of 10.8 months median DoR[5] was not yet reached for the 10 mg ICT01 dose.
Early survival signal: A 12-month OS[6] rate of 62% was observed, which is numerically higher than the ~54% reported for the Aza-Ven regimen in recent Phase 3 trials.
Favorable benefit–risk profile: Safety of the novel triplet regimen ICT01-Aza-Ven remains well manageable, with a 30-day mortality rate of 4%, and no deaths attributed to ICT01.
Regulatory momentum: ICT01 received Orphan Drug Designation from both FDA and EMA. The 10 mg ICT01 dose has been endorsed by FDA for further clinical development of the triplet regimen.
"ImCheck has in hand the alignment of strong clinical activity, a favorable safety profile, Orphan Drug Designations on both sides of the Atlantic, and now a clear regulatory-endorsed dose for ICT01 for accelerated late-stage development," added Pierre d’Epenoux, Chief Executive Officer of ImCheck Therapeutics. "These results arrive at a transformative moment for ImCheck, following the announced acquisition agreement with Ipsen. We remain deeply grateful to the patients, investigators, and our team for bringing ICT01 to this important inflection point."

SELLAS Life Sciences Presents Positive Phase 2 Data of SLS009 in Combination with AZA/VEN in Relapsed/Refractory AML-MR at ASH 2025

On December 7, 2025 SELLAS Life Sciences Group, Inc. (NASDAQ: SLS) ("SELLAS’’ or the "Company"), a late-stage clinical biopharmaceutical company focused on the development of novel therapies for a broad range of cancer indications, reported that clinical data from its ongoing Phase 2 study of SLS009, a highly selective CDK9 inhibitor, in combination with azacitidine (AZA) and venetoclax (VEN) for the treatment of patients with relapsed or refractory (R/R) acute myeloid leukemia (AML) with myelodysplastic syndrome-related changes (AML-MR) after prior VEN-based treatment were presented today at the 67th American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting and Exposition, being held December 6 – 9, 2025, in Orlando, Florida.

In this Phase 2 expansion study, R/R AML-MR patients (N = 35 evaluable) were studied in three separate cohorts (cohorts 3-5) who were previously treated with VEN-based regimens and either relapsed and/or were refractory to VEN and were then treated with SLS009 plus AZA/VEN. The median age of participating patients was 69 years, and 98% of patients had ELN adverse-risk AML, with the most frequent mutations being ASXL1, RUNX1, TP53, and SRSF2.

SLS009 in combination with AZA/VEN demonstrated clinically meaningful activity in patients with R/R AML-MR, and among the 35 evaluable patients, the overall response rate (CR+CRi+MLFS) was 46%, including 29% achieving CR/CRi. Patients harboring ASXL1 or TP53 mutations achieved response rates of 48% (19% CR/CRi) and 57% (29% CR/CRi), respectively. The median overall survival (mOS) was exceedingly higher than the expected 2.6 months in this R/R AML patient population, and in the least pretreated cohort, mOS reached 8.9 months. Across all cohorts, patients with one prior line of therapy experienced the greatest benefit, with a 58% response rate and mOS not yet reached. No dose-limiting toxicities (DLTs) or treatment-related deaths were observed, and the combination was well tolerated.

"These results further reinforce the therapeutic potential of SLS009 to overcome resistance to venetoclax-based regimens by suppressing the expression of MCL-1, a key mechanism of resistance to BCL-2 inhibition in AML," said Dr. Dragan Cicic, Senior Vice President and Chief Development Officer of SELLAS. "The combination of SLS009 with azacitidine and venetoclax demonstrates encouraging activity in a heavily pretreated population with adverse-risk AML-MR, including those harboring ASXL1 and TP53 mutations. We are particularly encouraged by the strong responses in patients with limited prior therapy and look forward to expanding this combination regimen into newly diagnosed AML with high-risk features."

Sonrotoclax Data at ASH 2025 Confirm Foundational Potential Across B-cell Malignancies

On December 7, 2025 BeOne Medicines Ltd. (Nasdaq: ONC; HKEX: 06160; SSE: 688235), a global oncology company, reported new data on sonrotoclax, a next-generation investigational BCL2 inhibitor, demonstrating meaningful clinical benefit as monotherapy and in combination across B-cell malignancies. These data were featured at the 67th American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting & Exposition in Orlando, Florida. The five presentations highlight durable responses in heavily pretreated patients with relapsed/refractory (R/R) mantle cell lymphoma (MCL) and additional studies showing deep, rapid, and sustained undetectable minimal residual disease (uMRD) rates with sonrotoclax-based combinations in patients with treatment-naive chronic lymphocytic leukemia (CLL), highlighting the foundational potential of this medicine.

"The data we’re presenting at ASH (Free ASH Whitepaper) 2025 are redefining what physicians can expect from sonrotoclax as a next-generation BCL2 inhibitor," said Amit Agarwal, M.D., Ph.D., Chief Medical Officer, Hematology, BeOne. "Our data demonstrates that sonrotoclax has succeeded where others have failed, achieving deep and durable responses as a monotherapy in both R/R CLL and MCL and notably fast kinetics as a combination therapy in treatment-naïve CLL. With these results, we believe sonrotoclax will become a foundational medicine in B-cell malignancies, potentially transforming outcomes for patients worldwide."

Sonrotoclax could become the first BCL2 inhibitor indicated for R/R MCL in the U.S., based on data showing an overall response rate (ORR) of 52.4%. (Oral Presentation: 663; December 7 from 5:00-5:15 PM EST)

In this Phase 1/2, global, multicenter, single-arm, open-label study (NCT05471843), ORR by IRC was 52.4% (95% CI, 42.4-62.4) with a complete response (CR) rate of 15.5% (95% CI, 9.1-24.0) in patients with R/R MCL post-treatment with anti-CD20 therapy and a BTK inhibitor treated with 320 mg of sonrotoclax (n=103). Notably, ORR by IRC benefit was consistent across patients with high-risk disease subtypes, including patients with TP53 mutation, a key prognostic marker for MCL. In this patient group, ORR by IRC was 59.1% (95% CI, 36.3-79.3).

At a median study follow-up of 14.2 months (range, 0.3-24.9 months), the median duration of response (DOR) by IRC was 15.8 months (95% CI, 7.4 months-NE) and has yet to reach full maturity. The median time to response (TTR) was 1.9 months (range 1.6-6.5 months), and the median progression-free survival (PFS) was 6.5 months (95% CI: 4.0-10.4).

Treatment with sonrotoclax monotherapy was generally well tolerated, and adverse events were manageable. The most common grade ≥3 treatment-emergent adverse events (TEAEs) in greater than 10% of patients were neutropenia (19.1%), infections (16.5%), and pneumonia (10.4%).

These data are under Priority Review by the U.S Food and Drug Administration for potential accelerated approval.

"Achieving deep and durable responses in relapsed or refractory mantle cell lymphoma after BTK inhibitor therapy has been a long-standing challenge," said Michael Wang, M.D., Professor, Department of Lymphoma and Myeloma, The University of Texas MD Anderson Cancer Center, and presenting author of the study. "In this analysis, sonrotoclax monotherapy demonstrated meaningful and lasting responses in heavily pretreated patients, including those with high-risk disease. These findings are highly encouraging and suggest this next-generation BCL2 inhibitor could play a foundational role in improving outcomes for patients with limited treatment options."

Sonrotoclax combinations demonstrate fast responses with unmatched uMRD rates and notably better kinetics than current options

BGB-11417-101 (NCT04277637) is an ongoing, phase 1/1b, dose-escalation/expansion study in patients with B-cell malignancies. Results presented at ASH (Free ASH Whitepaper) showcase data from sonrotoclax combinations in patients with treatment-naive (TN) CLL/SLL. Notable highlights include:

Sonrotoclax plus zanubrutinib (Poster Presentation: 3891)
In 135 efficacy-evaluable patients, ORR was 100%, with CR/CR with incomplete count recovery (CRi) in 55% of the 320-mg cohort. Median TTR was 2.6 months (range, 1.5-10.8 months).
At 48 weeks of combination treatment, the uMRD4 rate in the 320-mg cohort was 91% and uMRD rates continue to increase over time, with 98% of patients achieving uMRD4 by 96 weeks.
Median time from the initiation of the combination to uMRD4 was 4.5 months.
With a median study follow-up of 30.9 months, no progression events have been observed in the 320-mg cohort, including in the 40% of patients (34 patients) who had electively discontinued treatment.
The combination was generally well tolerated, with no TEAEs leading to death, or clinical or laboratory tumor lysis syndrome (TLS).
Sonrotoclax plus obinutuzumab (Oral Presentation: 793)
In the 320 mg efficacy-evaluable cohort (n=30), the ORR was 93%, with CR/CRi in 43% of patients.
The median time from reaching sonrotoclax target dose to uMRD was 2.3 months (range, 1.4-5.6 months) in the 320-mg cohort.
The combination was generally well tolerated, with no sonrotoclax discontinuations or deaths due to TEAEs.
Updated efficacy and safety data will be presented on Monday, December 8, 10:30 AM–10:45 AM EST.
Sonrotoclax plus zanubrutinib and obinutuzumab (Poster Presentation: 3890)
In 15 efficacy-evaluable patients, the ORR was 100%, with a CR/CRi rate of 40%.
Of the MRD-evaluable patients (n=10), 100% achieved uMRD4, discontinued treatment as mandated by the protocol, and remain in remission; 80% of patients achieved uMRD6.
With a median study follow-up of approximately 18.0 months, no PFS events have occurred.
The combination was generally well tolerated, and no deaths or discontinuations of any study drug due to TEAEs were observed.
Sonrotoclax monotherapy achieves an ORR by IRC of 76%, with a CR/CRi of 19%, in patients with R/R CLL/SLL, demonstrating rapid and deep responses (Poster Presentation: 5666)

BGB-11417-202 (NCT05479994) is an open-label, phase 2, and a potential registrational study evaluating the efficacy and safety of sonrotoclax in 100 heavily pretreated patients with R/R CLL/SLL. At a median follow-up of 14.4 months (range, 0.2-27.5 months), primary analysis results show:

Similar ORR and CR responses were seen in patients with unmutated IGHV, del(17p) and/or TP53 mutation, and BTK mutation. Median TTR was 3.7 months (range, 1.3-11.1 months).
The best blood uMRD rate was 49.0% (n=49/100). Median time to blood uMRD4 was 5.8 months (range, 3-12 months).
Sonrotoclax monotherapy was well tolerated, and toxicities were manageable and no clinical TLS occurred.
Updated data from the abstract will be presented on Monday, December 8, 6:00-8:00 PM EST. Additionally, these data are under review by China’s National Medical Products Administration (NMPA) for potential accelerated approval.

About Mantle Cell Lymphoma

Mantle cell lymphoma (MCL) is a rare subtype of aggressive B-cell non-Hodgkin lymphoma (NHL)1 that develops in B-cells located in the mantle zone of the lymph nodes. MCL accounts for approximately 5% of all NHL cases globally2, affecting an estimated 28,000 people3. MCL is often diagnosed at advanced stages4 and nearly all MCL patients will eventually develop refractory or relapsed (R/R) disease.5 The five-year survival rate for MCL is approximately 50%, reflecting the urgent need for new therapeutic options.6

About Chronic Lymphocytic Leukemia

Chronic lymphocytic leukemia (CLL) is a life-threatening cancer of adults. It is a type of mature B-cell malignancy in which abnormal leukemic B lymphocytes (a type of white blood cells) arise from the bone marrow and flood peripheral blood, bone marrow, and lymphoid tissues.7,8 CLL is the most common type of leukemia in adults, accounting for about one-third of new cases.2,9

About Sonrotoclax (BGB-11417)

Sonrotoclax is a next-generation and potentially best-in-class investigational B-cell lymphoma 2 (BCL2) inhibitor with a unique pharmacokinetic and pharmacodynamic profile. Laboratory studies during early drug development have shown that sonrotoclax is a highly potent and specific BCL2 inhibitor with a short half-life and no drug accumulation. Sonrotoclax has shown promising clinical activity across a range of B-cell malignancies and is in development as a monotherapy and in combination with other therapeutics, including BRUKINSA. Notably, in early clinical trials, sonrotoclax plus BRUKINSA has demonstrated rapid and unprecedented rates of undetectable minimal residual disease (uMRD) in treatment-naïve patients with CLL. To date, more than 2,200 patients have been enrolled across the broad sonrotoclax global development program.

The U.S. Food and Drug Administration (FDA) granted Breakthrough Therapy Designation (BTD) for sonrotoclax for the treatment of adult patients with relapsed or refractory (R/R) mantle cell lymphoma (MCL). In addition, the FDA has granted sonrotoclax Fast Track Designation for MCL and Waldenström macroglobulinemia, as well as Orphan Drug Designation for the treatment of adult patients with MCL, WM, multiple myeloma, acute myeloid leukemia, and myelodysplastic syndrome.

The information provided in this press release is intended for a global audience.

Yescarta® Delivers Consistent Safety, Efficacy, and Quality of Life Benefits Across Broad Range of Relapsed/Refractory Large B-cell Lymphoma Patients in New Analysis at ASH 2025

On December 7, 2025 Kite, a Gilead Company (Nasdaq: GILD), reported a new analysis demonstrating that second-line Yescarta (axicabtagene ciloleucel) therapy offers consistent benefits in patients with relapsed/refractory large B-cell lymphoma (R/R LBCL), even among those ineligible for the previous standard of care, high-dose chemotherapy followed by an autologous stem cell transplant (ASCT).

Results were shared from the combined analysis of four-year data from the landmark ZUMA-7 Phase 3 pivotal study of Yescarta for R/R LBCL and two-year data from the Phase 2 ALYCANTE study, designed by French collaborative group LYSA and sponsored by LYSARC, for transplant-ineligible patients. The findings were presented (Abstract #3714) during the 67th American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting and Exposition.

"Patients with large B-cell lymphoma who are ineligible for stem cell transplants face limited treatment options and poor outcomes due to age, co-morbidities and other factors," said Professor Roch Houot, Head of Haematology Department, University Hospital of Rennes, France and coordinator of the ALYCANTE study. "This analysis reinforces that Yescarta should be considered earlier in a patient’s treatment paradigm given its curative potential as a one-time treatment and further establishes CAR T as the new standard of care for second-line treatment of large B-cell lymphoma."

The efficacy analyses included 178 and 69 patients from the ZUMA-7 and ALYCANTE trials, respectively.

After two years:

Overall survival (OS) rate, meaning the percentage of patients in the trials who were still alive, was 64.9% in the pooled analysis, 62.8% in ZUMA-7, and 70.8% in ALYCANTE. Historically, the prognosis for R/R LBCL was very poor; prior to the introduction of new therapies like CAR Ts, the two-year survival rate was only about 20%.
Event-free survival (EFS) rate, meaning the percentage of patients who were still alive and had not seen their disease worsen or experienced other major complications, was 45.2% in the pooled analysis, 45.4% in ZUMA-7, and 44.7% in ALYCANTE.
Progression-free survival (PFS) rate, meaning the percentage of patients who were still living without their disease getting worse, was 47.4% in the pooled analysis, 47.6% in ZUMA-7, and 46.8% in ALYCANTE.
Additionally:

After three months, 55.6% of the patients in the pooled analysis showed a complete metabolic response (CMR), meaning their disease was barely, if at all, detectable. CMR was 51.2% in ZUMA-7 and 67.7% in ALYCANTE.
After one year after treatment, overall response rate (ORR), meaning patients saw their cancer significantly shrink or completely disappear, was 46.6% in the pooled analysis, 46.5% in ZUMA-7, and 46.8% in ALYCANTE.
For those patients who responded well to treatment, 61% saw that positive response continue after a full year. Pooled 12-month duration of response (DOR) was 61.0%, 60.6% in ZUMA-7, and 62.1% in ALYCANTE.
In the safety analysis, which included 170 ZUMA-7 and 62 ALYCANTE Yescarta-infused patients, safety outcomes were comparable between the two studies. The incidence of grade ≥3 treatment-emergent adverse events (TEAEs) was similar between the ZUMA-7 and ALYCANTE patients, 91.2% and 88.7% respectively, with a pooled incidence of 90.5%. Pooled incidence of grade ≥3 neurologic events, neutropenias, and anemia were 19.8% (ZUMA-7 21.2%, ALYCANTE 16.1%), 64.7% (ZUMA-7 70.0%, ALYCANTE 50.0%), and 27.6% (ZUMA-7 30.0%, ALYCANTE 21.0%), respectively.

Across both studies, patients generally experienced similar long-term improvements in their quality of life after initial treatment challenges. At Day 50 after treatment, patients in both trials showed a transient decline (-7.2 in ZUMA-7 and -6.3 in ALYCANTE) for EORTC QLQ-C30 global health status, and -12.9 for physical function in both. However, patients in ALYCANTE reported a meaningful improvement in their overall well-being (EQ-5D-5L VAS) by Day 100 (+9.9), while ZUMA-7 patients reached a similar meaningful improvement (+9.9) at Day 150, which continued through Month 12. By month 24, both ALYCANTE and ZUMA-7 showed continued improvements of global health status.

"This analysis offers compelling evidence of Yescarta’s consistent, durable efficacy and safety profile across a broad range of patients, including those with difficult-to-treat relapsed or refractory disease who historically faced very limited options and a poor prognosis," said Gallia Levy, MD, PhD, Senior Vice President and Global Head of Development, Kite. "These robust data further reinforce Yescarta’s potential as a treatment with curative intent, reflecting Kite’s deep commitment to transforming patient outcomes."

About LBCL

Globally, LBCL is the most common type of non-Hodgkin lymphoma. 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.

About ALYCANTE Study

ALYCANTE (NCT04531046) is a Phase 2 study evaluating the efficacy and safety of Yescarta in patients with R/R LBCL after one prior line of therapy who were deemed ineligible for high-dose chemotherapy and ASCT, sponsored by the LYSA/LYSARC collaborative group. The primary endpoint was the complete metabolic response at three months from Yescarta infusion. The study was funded by Kite, a Gilead Company, and carried out with Yescarta manufactured by Kite.

About LYSA and LYSARC

The Lymphoma Study Association (LYSA) is an independent, multidisciplinary network and an international leader in clinical lymphoma and CLL/WM research. With over 500 experts and a network of 90 centers across France, Belgium, and Portugal, it conducts clinical trials ranging from early-stage treatment evaluation to the development of new therapeutic strategies.

The Lymphoma Academic Research Organization (LYSARC), based in France, is the largest European academic organization dedicated to clinical lymphoma and CLL/WM research.

It manages and coordinates numerous clinical trials (phases 1 to 4) each year, as well as non-interventional and data reuse studies. LYSARC is a key research expert, leading innovative projects on an international scale.

About ZUMA-7 Study

Based on the primary efficacy endpoint results of ZUMA-7, the U.S. Food & Drug Administration approved Yescarta as initial treatment of R/R LBCL in April 2022. The EU granted approval in October 2022, followed by approvals in several other countries including Australia, Canada, Great Britain, Israel, Japan and Switzerland.

ZUMA-7 is a randomized, open-label, global, multicenter, Phase 3 study evaluating the safety and efficacy of Yescarta versus standard of care (SOC) for second-line therapy in adult patients with relapsed or refractory LBCL within 12 months of first-line therapy. The SOC for initial treatment of R/R LBCL has been a multi-step process involving platinum-based salvage combination chemotherapy regimen, and for responders, HDT and ASCT. In the study, 359 patients in 77 centers around the world were randomized (1:1) to receive a single infusion of Yescarta or SOC second-line treatment. The primary endpoint was 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 and OS. Additional secondary endpoints included 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.

U.S. IMPORTANT SAFETY INFORMATION

BOXED WARNING: CYTOKINE RELEASE SYNDROME, NEUROLOGIC TOXICITIES, and SECONDARY HEMATOLOGICAL MALIGNANCIES

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.
T cell malignancies have occurred following treatment of hematologic malignancies with BCMA- and CD19-directed genetically modified autologous T cell immunotherapies, including YESCARTA.
CYTOKINE RELEASE SYNDROME (CRS)

CRS, including fatal or life-threatening reactions, occurred following treatment with YESCARTA. CRS occurred in 90% (379/422) of patients with non-Hodgkin lymphoma (NHL), including ≥ Grade 3 CRS 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 CRS 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 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 (HLH/MAS).

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.

Confirm that 2 doses of tocilizumab are available prior to infusion of YESCARTA. Monitor patients at least daily for 7 days following infusion for signs and symptoms of CRS. Monitor patients for signs or symptoms of CRS for 2 weeks after infusion. 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 (ICANS) that were fatal or life-threatening occurred following treatment with YESCARTA. Neurologic toxicities occurred in 78% (330/422) of 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 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 in 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 higher grade of neurologic toxicities or prolongation of neurologic toxicities, delay the onset, and decrease the duration of CRS.

Monitor patients for signs and symptoms of neurologic toxicities following infusion at least daily for 7 days; and for 2 weeks thereafter and treat promptly. Advise patients to avoid driving for at least 2 weeks following infusion.

HYPERSENSITIVITY REACTIONS

Allergic reactions may occur with the infusion of YESCARTA. Serious hypersensitivity reactions, including anaphylaxis, may be due to dimethyl sulfoxide (DMSO) or residual gentamicin in YESCARTA.

SERIOUS INFECTIONS

Severe or life-threatening infections occurred after YESCARTA infusion. Infections (all grades) occurred in 45% of patients with NHL. Grade 3 or higher 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 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, has occurred in patients treated with drugs directed against B cells, including YESCARTA. Perform screening for HBV, HCV, and HIV and management 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 or higher 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 in patients receiving YESCARTA. 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

Patients treated with YESCARTA 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 YESCARTA. Mature T cell malignancies, including CAR-positive tumors, may present as soon as weeks following infusion, and may include fatal outcomes.

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