The data, presented in a rapid oral presentation (Abstract #8012) at the 2026 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting, support the clinical potential of CAR-T cell therapy in solid tumors.

Additionally, new analyses from the CARTITUDE program were presented, further highlighting sustained clinical benefit and a consistent safety profile for CARVYKTI (ciltacabtagene autoleucel; cilta-cel) in multiple myeloma.

"The data presented at ASCO (Free ASCO Whitepaper) underscores the progress of our next-generation pipeline and the meaningful impact that CARVYKTI continues to deliver to patients," said Ying Huang, Ph.D., Chief Executive Officer of Legend Biotech. "LB2102 marks an early step in expanding CAR-T cell therapy into solid tumors, addressing the unique challenges where current treatment options are limited and early data show promising clinical activity in difficult-to-treat cancers. At the same time, CARVYKTI continues to demonstrate durable efficacy and a consistent safety profile, reinforcing its role as a transformative therapy for multiple myeloma and supporting our leadership in cell therapy."

LB2102: Early Evidence of Clinical Activity Observed in Solid Tumors

Early Phase 1 results from the ongoing study of LB2102 demonstrate encouraging anti-tumor activity and a manageable safety profile in patients with relapsed or refractory (R/R) SCLC or LCNEC, a population characterized by advanced disease and limited treatment options.

LB2102 is an investigational DLL3-targeted autologous CAR-T cell therapy with dnTGFBR2 Armor engineered to enhance activity by overcoming immunosuppressive signaling within the tumor microenvironment.

Efficacy Results

Objective response rate (ORR): 20% (4/20)
Disease control rate (DCR): 70% (14/20)
At dose level ≥3:
ORR: 28.6%
DCR: 78.6%
Median duration of disease control: 6.1 months
Median duration of response: 6.5 months
Ongoing responses were observed in 2 patients at data cutoff
Safety Results

No dose-limiting toxicities or treatment-related deaths
Cytokine release syndrome (CRS) occurred in 30% of patients (all Grade ≤2)
Immune effector cell-associated neurotoxicity syndrome (ICANS) occurred in 15% of patients (two Grade 1 and one Grade 3)
Most Grade ≥3 adverse events were hematologic and co-attributed to lymphodepletion
"Patients with relapsed or refractory SCLC or LCNEC have historically had very limited treatment options and poor outcomes," said Zhonglin Hao, M.D., Ph.D., Professor of Medicine and Cancer Biology, Director, Thoracic Oncology Program, University of Kentucky Markey Cancer Center. "Durable disease control and responses at higher dose levels with LB2102 are encouraging, particularly alongside a manageable safety profile. These findings support continued evaluation of CAR-T approaches in solid tumors, where effective therapies remain limited."‡

LB2102 represents part of the Company’s broader strategy to expand CAR-T therapies beyond hematologic malignancies and into solid tumors. In November 2023, Legend Biotech’s subsidiary, Legend Biotech Ireland Limited, entered into a license agreement with Novartis Pharma AG (the Novartis Agreement), granting Novartis an exclusive worldwide license to develop, manufacture, and commercialize certain Legend Biotech CAR-T cell therapies targeting DLL3.

Under the Novartis Agreement, Legend Biotech is responsible for conducting the current Phase 1 clinical trial of LB2102 in the United States, while Novartis is responsible for conducting all other development, manufacturing, and commercialization for the licensed products, including LB2102.

CARVYKTI: Ongoing Clinical Data in Multiple Myeloma

New analyses from the CARTITUDE program continue to demonstrate sustained clinical benefit and consistent safety profile of CARVYKTI in patients with multiple myeloma.

In the CARTITUDE-4 subgroup analysis (Abstract #7536), progression-free survival and overall survival benefits were observed across both high-risk and standard-risk cytogenetic populations among patients who responded to bridging therapy, with 30-month OS rates greaterthan 85%.No cases of immune effector cell (IEC)–associated Parkinsonism were reported.

In a separate multi-study analysis (Abstract #7533), a low incidence (1.2%) of IEC-associated enterocolitis (IEC-EC) was observed, further characterizing this uncommon adverse event and reinforcing the overall favorable benefit-risk profile of CARVYKTI.

CARVYKTI is the first and only BCMA-targeted CAR-T cell therapy approved for the treatment of patients with multiple myeloma who have had at least one prior line of therapy. Globally, CARVYKTI is now commercially available in 18 countries and has been used to treat more than 10,000 patients to date.

CARVYKTI IMPORTANT SAFETY INFORMATION

WARNING: CYTOKINE RELEASE SYNDROME, NEUROLOGIC TOXICITIES, HLH/MAS, PROLONGED and RECURRENT CYTOPENIA, and SECONDARY HEMATOLOGICAL MALIGNANCIES

Cytokine Release Syndrome (CRS), including fatal or life-threatening reactions, occurred in patients following treatment with CARVYKTI. Do not administer CARVYKTI to patients with active infection or inflammatory disorders. Treat severe or life-threatening CRS with tocilizumab or tocilizumab and corticosteroids.

Immune Effector Cell-associated Neurotoxicity Syndrome (ICANS), which may be fatal or life-threatening, occurred following treatment with CARVYKTI, including before CRS onset, concurrently with CRS, after CRS resolution, or in the absence of CRS.

Hemophagocytic Lymphohistiocytosis/Macrophage Activation Syndrome (HLH/MAS), including fatal and life-threatening reactions, occurred in patients following treatment with CARVYKTI. HLH/MAS can occur with CRS or neurologic toxicities.

Prolonged and/or recurrent cytopenias with bleeding and infection and requirement for stem cell transplantation for hematopoietic recovery occurred following treatment with CARVYKTI.

Immune Effector Cell-associated Enterocolitis (IEC-EC), including fatal or life-threatening reactions, occurred following treatment with CARVYKTI.

Secondary hematological malignancies, including myelodysplastic syndrome and acute myeloid leukemia, have occurred in patients following treatment with CARVYKTI. T-cell malignancies have occurred following treatment of hematologic malignancies with BCMA- and CD19-directed genetically modified autologous T-cell immunotherapies, including CARVYKTI.
WARNINGS AND PRECAUTIONS

INCREASED EARLY MORTALITY – In CARTITUDE-4, a (1:1) randomized controlled trial, there was a numerically higher percentage of early deaths in patients randomized to the CARVYKTI treatment arm compared to the control arm. Among patients with deaths occurring within the first 10 months from randomization, a greater proportion (29/208; 14%) occurred in the CARVYKTI arm compared to (25/211; 12%) in the control arm. Of the 29 deaths that occurred in the CARVYKTI arm within the first 10 months of randomization, 10 deaths occurred prior to CARVYKTI infusion, and 19 deaths occurred after CARVYKTI infusion. Of the 10 deaths that occurred prior to CARVYKTI infusion, all occurred due to disease progression, and none occurred due to adverse events. Of the 19 deaths that occurred after CARVYKTI infusion, 3 occurred due to disease progression, and 16 occurred due to adverse events. The most common adverse events were due to infection (n=12).

CYTOKINE RELEASE SYNDROME (CRS), including fatal or life-threatening reactions, occurred following treatment with CARVYKTI. Among patients receiving CARVYKTI for RRMM in the CARTITUDE-1 & -4 studies (N=285), CRS occurred in 84% (238/285), including ≥ Grade 3 CRS (ASTCT 2019) in 4% (11/285) of patients. Median time to onset of CRS, any grade, was 7 days (range: 1 to 23 days). CRS resolved in 82% with a median duration of 4 days (range: 1 to 97 days). The most common manifestations of CRS in all patients combined (≥10%) included fever (84%), hypotension (29%) and aspartate aminotransferase increased (11%). Serious events that may be associated with CRS include pyrexia, hemophagocytic lymphohistiocytosis, respiratory failure, disseminated intravascular coagulation, capillary leak syndrome, and supraventricular and ventricular tachycardia. CRS occurred in 78% of patients in CARTITUDE-4 (3% Grade 3 to 4) and in 95% of patients in CARTITUDE-1 (4% Grade 3 to 4).

Identify CRS based on clinical presentation. Evaluate for and treat other causes of fever, hypoxia, and hypotension. CRS has been reported to be associated with findings of HLH/MAS, and the physiology of the syndromes may overlap. HLH/MAS is a potentially life-threatening condition. In patients with progressive symptoms of CRS or refractory CRS despite treatment, evaluate for evidence of HLH/MAS.

Confirm that a minimum of 2 doses of tocilizumab are available prior to infusion of CARVYKTI.

Of the 285 patients who received CARVYKTI in clinical trials, 53% (150/285) patients received tocilizumab; 35% (100/285) received a single dose, while 18% (50/285) received more than 1 dose of tocilizumab. Overall, 14% (39/285) of patients received at least 1 dose of corticosteroids for treatment of CRS.

Monitor patients at least daily for 7 days following CARVYKTI infusion for signs and symptoms of CRS. Monitor patients for signs or symptoms of CRS for at least 2 weeks after infusion. At the first sign of CRS, immediately institute treatment with supportive care, tocilizumab, or tocilizumab and corticosteroids.

Counsel patients to seek immediate medical attention should signs or symptoms of CRS occur at any time.

NEUROLOGIC TOXICITIES, which may be severe, life-threatening, or fatal, occurred following treatment with CARVYKTI. Neurologic toxicities included ICANS, neurologic toxicity with signs and symptoms of Parkinsonism, GBS, immune mediated myelitis, peripheral neuropathies, and cranial nerve palsies. Counsel patients on the signs and symptoms of these neurologic toxicities, and on the delayed nature of onset of some of these toxicities. Instruct patients to seek immediate medical attention for further assessment and management if signs or symptoms of any of these neurologic toxicities occur at any time.

Among patients receiving CARVYKTI in the CARTITUDE-1 & 4 studies for RRMM, one or more neurologic toxicities occurred in 24% (69/285), including ≥ Grade 3 cases in 7% (19/285) of patients. Median time to onset was 10 days (range: 1 to 101) with 63/69 (91%) of cases developing by 30 days. Neurologic toxicities resolved in 72% (50/69) of patients with a median duration to resolution of 23 days (range: 1 to 544). Of patients developing neurotoxicity, 96% (66/69) also developed CRS. Subtypes of neurologic toxicities included ICANS in 13%, peripheral neuropathy in 7%, cranial nerve palsy in 7%, parkinsonism in 3%, and immune mediated myelitis in 0.4% of the patients.

Immune Effector Cell-Associated Neurotoxicity Syndrome (ICANS): Patients receiving CARVYKTI may experience fatal or life-threatening ICANS following treatment with CARVYKTI, including before CRS onset, concurrently with CRS, after CRS resolution, or in the absence of CRS.

Among patients receiving CARVYKTI in the CARTITUDE-1 & -4 studies, ICANS occurred in 13% (36/285), including Grade ≥3 in 2% (6/285) of the patients. Median time to onset of ICANS was 8 days (range: 1 to 28 days). ICANS resolved in 30 of 36 (83%) of patients, with a median time to resolution of 3 days (range: 1 to 143 days). Median duration of ICANS was 6 days (range: 1 to 1229 days) in all patients, including those with ongoing neurologic events at the time of death or data cutoff. Of patients with ICANS, 97% (35/36) had CRS. The onset of ICANS occurred during CRS in 69% of patients, before and after the onset of CRS in 14% of patients, respectively.

Immune Effector Cell-associated Neurotoxicity Syndrome occurred in 7% of patients in CARTITUDE-4 (0.5% Grade 3) and in 23% of patients in CARTITUDE-1 (3% Grade 3). The most frequent (≥2%) manifestations of ICANS included encephalopathy (12%), aphasia (4%), headache (3%), motor dysfunction (3%), ataxia (2%), and sleep disorder (2%).

Monitor patients at least daily for 7 days following CARVYKTI infusion for signs and symptoms of ICANS. Rule out other causes of ICANS symptoms. Monitor patients for signs or symptoms of ICANS for at least 2 weeks after infusion and treat promptly. Neurologic toxicity should be managed with supportive care and/or corticosteroids as needed. Advise patients to avoid driving for at least 2 weeks following infusion.

Parkinsonism: Neurologic toxicity with parkinsonism has been reported in clinical trials of CARVYKTI. Among patients receiving CARVYKTI in the CARTITUDE-1 & -4 studies, parkinsonism occurred in 3% (8/285), including Grade ≥3 in 2% (5/285) of the patients. Median time to onset of parkinsonism was 56 days (range: 14 to 914 days). Parkinsonism resolved in 1 of 8 (13%) of patients with a median time to resolution of 523 days. Median duration of parkinsonism was 243.5 days (range: 62 to 720 days) in all patients, including those with ongoing neurologic events at the time of death or data cutoff. The onset of parkinsonism occurred after CRS for all patients and after ICANS for 6 patients.

Parkinsonism occurred in 1% of patients in CARTITUDE-4 (no Grade 3 to 4) and in 6% of patients in CARTITUDE-1 (4% Grade 3 to 4).

Manifestations of parkinsonism included movement disorders, cognitive impairment, and personality changes. Monitor patients for signs and symptoms of parkinsonism that may be delayed in onset and managed with supportive care measures. There is limited efficacy information with medications used for the treatment of Parkinson’s disease for the improvement or resolution of parkinsonism symptoms following CARVYKTI treatment.

Guillain-Barré Syndrome: A fatal outcome following GBS occurred following treatment with CARVYKTI despite treatment with intravenous immunoglobulins. Symptoms reported include those consistent with Miller-Fisher variant of GBS, encephalopathy, motor weakness, speech disturbances, and polyradiculoneuritis.

Monitor for GBS. Evaluate patients presenting with peripheral neuropathy for GBS. Consider treatment of GBS with supportive care measures and in conjunction with immunoglobulins and plasma exchange, depending on severity of GBS.

Immune Mediated Myelitis: Grade 3 myelitis occurred 25 days following treatment with CARVYKTI in CARTITUDE-4 in a patient who received CARVYKTI as subsequent therapy. Symptoms reported included hypoesthesia of the lower extremities and the lower abdomen with impaired sphincter control. Symptoms improved with the use of corticosteroids and intravenous immune globulin. Myelitis was ongoing at the time of death from other cause.

Peripheral Neuropathy occurred following treatment with CARVYKTI. Among patients receiving CARVYKTI in the CARTITUDE-1 & -4 studies, peripheral neuropathy occurred in 7% (21/285), including Grade ≥3 in 1% (3/285) of the patients. Median time to onset of peripheral neuropathy was 57 days (range: 1 to 914 days). Peripheral neuropathy resolved in 11 of 21 (52%) of patients with a median time to resolution of 58 days (range: 1 to 215 days). Median duration of peripheral neuropathy was 149.5 days (range: 1 to 692 days) in all patients, including those with ongoing neurologic events at the time of death or data cutoff.

Peripheral neuropathies occurred in 7% of patients in CARTITUDE-4 (0.5% Grade 3 to 4) and in 7% of patients in CARTITUDE-1 (2% Grade 3 to 4). Monitor patients for signs and symptoms of peripheral neuropathies. Patients who experience peripheral neuropathy may also experience cranial nerve palsies or GBS.

Cranial Nerve Palsies occurred following treatment with CARVYKTI. Among patients receiving CARVYKTI in the CARTITUDE-1 & -4 studies, cranial nerve palsies occurred in 7% (19/285), including Grade ≥3 in 1% (1/285) of the patients. Median time to onset of cranial nerve palsies was 21 days (range: 17 to 101 days). Cranial nerve palsies resolved in 17 of 19 (89%) of patients with a median time to resolution of 66 days (range: 1 to 209 days). Median duration of cranial nerve palsies was 70 days (range: 1 to 262 days) in all patients, including those with ongoing neurologic events at the time of death or data cutoff. Cranial nerve palsies occurred in 9% of patients in CARTITUDE-4 (1% Grade 3 to 4) and in 3% of patients in CARTITUDE-1 (1% Grade 3 to 4).

The most frequent cranial nerve affected was the 7th cranial nerve. Additionally, cranial nerves III, V, and VI have been reported to be affected.

Monitor patients for signs and symptoms of cranial nerve palsies. Consider management with systemic corticosteroids, depending on the severity and progression of signs and symptoms.

HEMOPHAGOCYTIC LYMPHOHISTIOCYTOSIS (HLH)/MACROPHAGE ACTIVATION SYNDROME (MAS): Among patients receiving CARVYKTI in the CARTITUDE-1 & -4 studies, HLH/MAS occurred in 1% (3/285) of patients. All events of HLH/MAS had onset within 99 days of receiving CARVYKTI, with a median onset of 10 days (range: 8 to 99 days), and all occurred in the setting of ongoing or worsening CRS. The manifestations of HLH/MAS included hyperferritinemia, hypotension, hypoxia with diffuse alveolar damage, coagulopathy and hemorrhage, cytopenia, and multi-organ dysfunction, including renal dysfunction and respiratory failure.

Patients who develop HLH/MAS have an increased risk of severe bleeding. Monitor hematologic parameters in patients with HLH/MAS and transfuse per institutional guidelines. Fatal cases of HLH/MAS occurred following treatment with CARVYKTI.

HLH is a life-threatening condition with a high mortality rate if not recognized and treated early. Treatment of HLH/MAS should be administered per institutional standards.

PROLONGED AND RECURRENT CYTOPENIAS: Patients may exhibit prolonged and recurrent cytopenias following lymphodepleting chemotherapy and CARVYKTI infusion.

Among patients receiving CARVYKTI in the CARTITUDE-1 & -4 studies, Grade 3 or higher cytopenias not resolved by Day 30 following CARVYKTI infusion occurred in 62% (176/285) of the patients and included thrombocytopenia 33% (94/285), neutropenia 27% (76/285), lymphopenia 24% (67/285), and anemia 2% (6/285). After Day 60 following CARVYKTI infusion, 22%, 20%, 5%, and 6% of patients had a recurrence of Grade 3 or 4 lymphopenia, neutropenia, thrombocytopenia, and anemia, respectively, after initial recovery of their Grade 3 or 4 cytopenia. Seventy-seven percent (219/285) of patients had one, two, or three or more recurrences of Grade 3 or 4 cytopenias after initial recovery of Grade 3 or 4 cytopenia. Sixteen and 25 patients had Grade 3 or 4 neutropenia and thrombocytopenia, respectively, at the time of death.

Monitor blood counts prior to and after CARVYKTI infusion. Manage cytopenias with growth factors and blood product transfusion support according to local institutional guidelines.

INFECTIONS: CARVYKTI should not be administered to patients with active infection or inflammatory disorders. Severe, life-threatening, or fatal infections occurred in patients after CARVYKTI infusion.

Among patients receiving CARVYKTI in the CARTITUDE-1 & -4 studies, infections occurred in 57% (163/285), including Grade ≥3 in 24% (69/285) of patients. Grade 3 or 4 infections with an unspecified pathogen occurred in 12%, viral infections in 6%, bacterial infections in 5%, and fungal infections in 1% of patients. Overall, 5% (13/285) of patients had Grade 5 infections, 2.5% of which were due to COVID-19. Patients treated with CARVYKTI had an increased rate of fatal COVID-19 infections compared to the standard therapy arm.

Monitor patients for signs and symptoms of infection before and after CARVYKTI infusion and treat patients appropriately. Administer prophylactic, pre-emptive, and/or therapeutic antimicrobials according to the standard institutional guidelines. Febrile neutropenia was observed in 5% of patients after CARVYKTI infusion 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. Counsel patients on the importance of prevention measures. Follow institutional guidelines for the vaccination and management of immunocompromised patients with COVID-19.

Viral Reactivation: Hepatitis B virus (HBV) reactivation, in some cases resulting in fulminant hepatitis, hepatic failure, and death, can occur in patients with hypogammaglobulinemia. Perform screening for Cytomegalovirus (CMV), HBV, hepatitis C virus (HCV), and human immunodeficiency virus (HIV) or any other infectious agents if clinically indicated in accordance with clinical guidelines before collection of cells for manufacturing. Consider antiviral therapy to prevent viral reactivation per local institutional guidelines/clinical practice.

Reactivation of John Cunningham (JC) virus, leading to progressive multifocal leukoencephalopathy (PML), including cases with fatal outcomes, have been reported following treatment. Perform appropriate diagnostic evaluations in patients with neurological adverse events.

HYPOGAMMAGLOBULINEMIA: can occur in patients receiving treatment with CARVYKTI. Among patients receiving CARVYKTI in the CARTITUDE-1 & -4 studies, hypogammaglobulinemia adverse event was reported in 36% (102/285) of patients; laboratory IgG levels fell below 500 mg/dL after infusion in 93% (265/285) of patients. Hypogammaglobulinemia either as an adverse reaction or laboratory IgG level below 500 mg/dL after infusion occurred in 94% (267/285) of patients treated. Fifty-six percent (161/285) of patients received intravenous immunoglobulin (IVIG) post CARVYKTI for either an adverse reaction or prophylaxis.

Monitor immunoglobulin levels after treatment with CARVYKTI and administer IVIG for IgG <400 mg/dL. Manage per local institutional guidelines, including infection precautions and antibiotic or antiviral prophylaxis.

Use of Live Vaccines: The safety of immunization with live viral vaccines during or following CARVYKTI 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 CARVYKTI treatment, and until immune recovery following treatment with CARVYKTI.

HYPERSENSITIVITY REACTIONS occurred following treatment with CARVYKTI. Among patients receiving CARVYKTI in the CARTITUDE-1 & -4 studies, hypersensitivity reactions occurred in 5% (13/285), all of which were ≤2 Grade. Manifestations of hypersensitivity reactions included flushing, chest discomfort, tachycardia, wheezing, tremor, burning sensation, non-cardiac chest pain, and pyrexia.

Serious hypersensitivity reactions, including anaphylaxis, may be due to the dimethyl sulfoxide (DMSO) in CARVYKTI. Patients should be carefully monitored for 2 hours after infusion for signs and symptoms of severe reaction. Treat promptly and manage patients appropriately according to the severity of the hypersensitivity reaction.

IMMUNE EFFECTOR CELL-ASSOCIATED ENTERCOLITIS (IEC-EC) has occurred in patients treated with CARVYKTI. Manifestations include severe or prolonged diarrhea, abdominal pain, and weight loss requiring parenteral nutrition. IEC-EC has been associated with fatal outcome from perforation or sepsis. Manage according to institutional guidelines, including referral to gastroenterology and infectious disease specialists.

In cases of refractory IEC-EC, consider additional workup to exclude alternative etiologies, including T-cell lymphoma of the GI tract, which has been reported in the post marketing setting.

SECONDARY MALIGNANCIES: Patients treated with CARVYKTI may develop secondary malignancies. Among patients receiving CARVYKTI in the CARTITUDE-1 & -4 studies, myeloid neoplasms occurred in 5% (13/285) of patients (9 cases of myelodysplastic syndrome, 3 cases of acute myeloid leukemia, and 1 case of myelodysplastic syndrome followed by acute myeloid leukemia). The median time to onset of myeloid neoplasms was 447 days (range: 56 to 870 days) after treatment with CARVYKTI. Ten of these 13 patients died following the development of myeloid neoplasms; 2 of the 13 cases of myeloid neoplasm occurred after initiation of subsequent antimyeloma therapy. Cases of myelodysplastic syndrome and acute myeloid leukemia have also been reported in the post marketing setting. T-cell malignancies have occurred following treatment of hematologic malignancies with BCMA- and CD19-directed genetically modified autologous T-cell immunotherapies, including CARVYKTI. Mature T-cell malignancies, including CAR-positive tumors, may present as soon as weeks following infusions, and may include fatal outcomes.

Monitor lifelong for secondary malignancies. In the event that a secondary malignancy occurs, contact Janssen Biotech, Inc., at 1-800-526-7736 for reporting and to obtain instructions on collection of patient samples.

ABOUT CARVYKTI (CILTACABTAGENE AUTOLEUCEL; CILTA-CEL)
Ciltacabtagene autoleucel is a BCMA-directed, genetically modified autologous T-cell immunotherapy, which involves reprogramming a patient’s own T-cells with a transgene encoding a chimeric antigen receptor (CAR) that identifies and eliminates cells that express BCMA. The cilta-cel CAR protein features two BCMA-targeting single-domain antibodies designed to confer high avidity against human BCMA. Upon binding to BCMA-expressing cells, the CAR promotes T-cell activation, expansion, and elimination of target cells.i

In December 2017, Legend Biotech entered into an exclusive worldwide license and collaboration agreement with Janssen Biotech, Inc., a Johnson & Johnson company, to develop and commercialize cilta-cel. In February 2022, cilta-cel was approved by the U.S. Food and Drug Administration (FDA) under the brand name CARVYKTI for the treatment of adults with relapsed or refractory multiple myeloma. In April 2024, cilta-cel was approved for the second-line treatment of patients with relapsed/refractory myeloma who have received at least one prior line of therapy, including a proteasome inhibitor, an immunomodulatory agent, and are refractory to lenalidomide.

In May 2022, the European Commission (EC) granted conditional marketing authorization of CARVYKTI for the treatment of adults with relapsed and refractory multiple myeloma. In September 2022, Japan’s Ministry of Health, Labour and Welfare (MHLW) approved CARVYKTI. Cilta-cel was granted Breakthrough Therapy Designation in the U.S. in December 2019 and in China in August 2020. In addition, cilta-cel received a PRIority MEdicines (PRIME) designation from the European Commission in April 2019. Cilta-cel also received Orphan Drug Designation from the U.S. FDA in February 2019, from the European Commission in February 2020, and from the Pharmaceuticals and Medicinal Devices Agency (PMDA) in Japan in June 2020. In March 2022, the European Medicines Agency’s Committee for Orphan Medicinal Products recommended by consensus that the orphan designation for cilta-cel be maintained on the basis of clinical data demonstrating improved and sustained complete response rates following treatment.

ABOUT MULTIPLE MYELOMA
Multiple myeloma is an incurable blood cancer that starts in the bone marrow and is characterized by an excessive proliferation of plasma cells.ii In 2024, it is estimated that more than 35,000 people will be diagnosed with multiple myeloma, and more than 12,000 people will die from the disease in the U.S.iii While some patients with multiple myeloma initially have no symptoms, most patients are diagnosed due to symptoms that can include bone problems, low blood counts, calcium elevation, kidney problems, or infections.iv

ABOUT CARTITUDE-4

Christina Coughlin, CEO of Avacta, commented:

"Today’s data further underscores our confidence in both our Gen One product faridoxorubicin (AVA6000) and our pre|CISION technology to significantly improve treatment options for cancer patients.

"We are particularly encouraged by signs of efficacy in patients with salivary gland cancers (SGC and the consistency of these data from Phase 1a and 1b support the potential for this agent to move to later stage trials. The excellent safety profile was further demonstrated by the absence of severe cardiac toxicity and lifting of the lifetime maximum, following careful analysis of drug concentration versus effect on the heart.

"We look forward to presenting further data updates from this trial later in June, at the BIO International Convention."

Faridoxorubicin demonstrates favorable safety and consistent efficacy in Phase 1a and the Phase 1b SGC expansion cohort: At the recommended dose for expansion (RDE) of 310 mg/m2, faridoxorubicin (AVA6000) demonstrated a safety profile consistent with that seen earlier during Phase 1a dose escalation, when comparing grade 3/4 adverse events. The rates of toxicities remain lower than those historically observed with conventional doxorubicin, despite the RDE representing a dose level that is nearly three times the maximum tolerated dose of conventional doxorubicin level (75 mg/m2).

Efficacy among patients in the SGC expansion cohort also remained consistent, with multiple confirmed responses (four partial responses and nine minor responses observed among 38 evaluable patients). The disease control rate remains consistent at 92% (35/38 with best response of stable disease or response). Nine patients are continuing treatment, and a further 11 patients remain in follow up for disease progression.

PK and exposure-response data lead to lifting of lifetime maximum exposure: Active doxorubicin is released following dosing with faridoxorubicin, as is cleaved from the inert drug by the FAP enzyme in the tumor microenvironment (TME). Only a small fraction of the active payload subsequently enters the circulation and reaches other organs, including the heart, with a delay and at lower concentrations. This contrasts with the profile seen with conventional doxorubicin dosed intravenously, which delivers high systemic concentrations from the outset. Here, released doxorubicin is rapidly distributed, and eliminated more slowly, consistent with the known PK of conventional doxorubicin.

Preliminary Population PK (PopPK) modeling demonstrates that the sharp systemic Cmax peaks, which are typical with conventional doxorubicin dosing, are eliminated with AVA6000. AVA6000 dosing results in higher clearance and larger central volume of distribution for released doxorubicin, compared with conventional doxorubicin. This shows that released doxorubicin enters plasma gradually following FAP-mediated cleavage in the TME.

There were no severe cardiac toxicity events reported and only minimal changes in left ventricular function (as measured by left ventricular ejection fraction, LVEF) observed in the 111 patients dosed to date, even with a subset of patients having reached the (protocol-defined) lifetime maximum exposure of 550 mg/m2. Only four patients (<4%) reported significant reductions in LVEF and no cardiomyopathy events of any grade were observed.

Due to limited evidence of cardiac toxicity, an exposure-response analysis was conducted to assess the relationship between exposure to released doxorubicin and changes in LVEF on a per-patient basis. This analysis found no meaningful relationship between the LVEF changes and released doxorubicin exposure, suggesting that the cardiac toxicity observed with conventional dosing of doxorubicin is not observed with released doxorubicin from faridoxorubicin. This supported removal of the lifetime maximum limit of dosing. The Company received Health Authority agreement with this conclusion and hence the limit was removed from the study protocol earlier this year.

The study continues to enroll patients and Avacta plans to present further data on the AVA6000 program at BIO International Convention, taking place June 22-25, 2026 in San Diego, CA, USA.

As previously reported at ENETS 2025, the Phase 3 COMPETE trial met its primary endpoint, with 177Lu-edotreotide (ITM-11) demonstrating clinically and statistically significant improvement in progression-free survival compared to everolimus (23.9 vs. 14.1 months; p=0.022). Results from a prospective dosimetry sub-study of COMPETE were presented at EANM 2025. Data, which included one of the largest prospective dosimetry datasets ever generated in a Phase 3 radiopharmaceutical trial, demonstrated that 177Lu-edotreotide (ITM-11) delivered targeted radiation to tumors while maintaining healthy organ exposure well below established safety thresholds. Building on this dataset, investigators applied PBMS NLMEM modeling to evaluate whether accurate individualized dose estimates for kidneys and tumors could be achieved from a single imaging session.

"Individualized dosimetry has long been recognized as clinically valuable in radiopharmaceutical therapy, but widespread implementation has been limited by the complexity and burden of repeated imaging procedures," said Dr. Deni Hardiansyah, co-author and associate professor at the University of Indonesia. "These findings demonstrate that a population-based modeling approach may enable accurate dosimetry estimates using substantially fewer imaging timepoints, supporting more practical integration into routine clinical practice."

The analysis utilized dosimetry data from patients treated with 177Lu-edotreotide in the Phase 3 COMPETE trial, including planar and SPECT/CT imaging data collected from 207 kidney datasets and 154 tumor datasets. Investigators evaluated the accuracy of PBMS NLMEM-derived single-timepoint dosimetry estimates compared with established Madsen and Hänscheid approaches.

Key findings included:

The PBMS NLMEM approach accurately estimated absorbed doses for both kidneys and tumors using a single imaging timepoint, achieving mean absolute percentage error (MAPE) values of 3–20% for kidney dosimetry across evaluated timepoints
PBMS NLMEM outperformed comparator single-timepoint dosimetry methods with respect to MAPE and R20 for kidney absorbed dose estimation across all evaluated timepoints
Findings suggest individualized dosimetry may be achievable with just one scan approximately six hours after treatment, offering an alternative for centers with limited imaging capacity and potentially expanding the routine use of personalized dosimetry
"These data build on the extensive dosimetry dataset generated through the COMPETE trial and reflect ITM’s continued commitment to advancing precision radiopharmaceutical therapy," said Dr. Celine Wilke, chief medical officer of ITM. "The possibility of accurate, same-day dosimetry from a single scan may help reduce patient burden and workflow complexity, as well as reduce inter-center disparities, making personalized dosimetry practical for a far broader range of clinical settings."

About the COMPETE Trial
The COMPETE trial (NCT03049189) evaluated 177Lu-edotreotide (ITM-11), a proprietary, synthetic, targeted radiotherapeutic investigational agent compared to everolimus, a targeted molecular therapy, in patients with inoperable, progressive Grade 1 or Grade 2 gastroenteropancreatic neuroendocrine tumors (GEP-NETs). This trial met its primary endpoint, with 177Lu-edotreotide demonstrating clinically and statistically significant improvement in progression-free survival (PFS) compared to everolimus. 177Lu-edotreotide is an investigational product pending review by the U.S. Food and Drug Administration (FDA) and is not approved by any regulatory authority for the safety and/or efficacy of any intended use. It is also being evaluated in COMPOSE, a Phase 3 study in patients with well-differentiated, aggressive Grade 2 or Grade 3, somatostatin receptor (SSTR)-positive GEP-NETs.

"The consistency of the survival benefit, the depth and durability of responses, and the favorable safety profile observed across studies with both gemcitabine/Abraxane and FOLFIRINOX continue to underscore the broad clinical promise of elraglusib in combination with established chemotherapy regimens," said Daniel Schmitt, President & Chief Executive Officer of Actuate. "We believe these data further strengthen the positioning of elraglusib as a potentially differentiated backbone therapy and expand future development opportunities in key patient populations across multiple combination settings. The potential to combine with RAS/RAF/MEK inhibitors in patients where those therapies would be appropriate, along with significant survival benefit in patients without those molecular mutations, speaks to the broad therapeutic potential of elraglusib. Looking ahead, the planned addition of our oral formulation should enable broader combination strategies, greater dosing flexibility, and expanded clinical and commercial potential."

Title: Post-hoc efficacy and biomarker analysis of elraglusib plus gemcitabine/nab-paclitaxel versus chemotherapy alone in metastatic pancreatic ductal adenocarcinoma

First Author: Devalingam Mahalingam, MD, PhD, Gastrointestinal Oncologist and Professor of Medicine at Northwestern University Feinberg School of Medicine

A comprehensive post-hoc efficacy and biomarker analysis of the randomized Phase 2 1801 Part 3B study showed that elraglusib plus gemcitabine/nab-paclitaxel (GnP), compared with GnP alone, provided meaningful clinical benefit across multiple patient subgroups in previously untreated mPDAC.

Key Findings from the Analysis

Striking survival advantages of elraglusib/GnP vs GnP alone were observed in patients with wild-type (WT) tumor genomics:
Patients with KRAS WT treated with elraglusib/GnP achieved a mOS of 16.9 vs 10.1 months (p<0.001), a nearly 7-month improvement.
This survival advantage was consistent across key tumor suppressor gene subgroups analyzed:
TP53 WT: 13.4 vs 7.6 months, (p=0.002)
CDKN2A WT: 10.4 vs 7.6 months, (p=0.002)
SMAD4 WT: 10.1 vs 7.1 months, (p=0.003)
Positive OS trends were observed in both the intent-to-treat (ITT) and modified intent-to-treat (mITT) populations treated with elraglusib plus GnP versus GnP alone.
In a landmark analysis of patients completing at least one treatment cycle, mOS was approximately 12.5 months in the elraglusib/GnP arm compared with 8.5 months in the GnP control arm, with a near doubling of the one-year survival rate versus GnP alone.
Exploratory subgroup analyses demonstrated improved OS in patients treated with elraglusib/GnP vs GnP who had:
ECOG performance status of 0 (12.2 vs 8.0 months; p=0.007)
Baseline albumin ≥3 g/dL (10.8 vs 7.6 months; p=0.02)
Baseline CA19-9 <8000 U/mL (12.2 vs 7.8 months; p=0.01)
Lower tumor grade (Grade 1+2, 14.3 vs 7.8 months, p=0.005)
Lower tumor mutational burden, lower circulating tumor DNA (ctDNA) fraction, and lower tumor grade were correlated with improved survival outcomes only in elraglusib/GnP-treated patients, providing a foundation for prospective patient selection in future studies.
Title: A Phase II Study of FOLFIRINOX (FFX) Combined with the Glycogen Synthase Kinase-3 Beta (GSK-3β) Inhibitor Elraglusib (ELRA) and the Transforming Growth
Factor-β (TGF-β) Inhibitor Losartan (LOS) in Patients with Untreated Metastatic Pancreatic Ductal Adenocarcinoma (mPDAC)

First Author: Priyadarshini Pathak, Mass General Brigham Cancer Institute, Boston, USA

The Phase 2 study evaluated elraglusib in combination with FFX and losartan (LOS) across four treatment arms in a first-line population of patients with mPDAC.

Key Findings

Arms incorporating elraglusib demonstrated meaningful improvement: elraglusib/FFX and elraglusib/FFX+LOS each achieved mOS of 9.8 months and mPFS of 6.0 and 6.5 months, respectively, vs 7.7 months and PFS of 5.1 with FFX alone.
A subset of patients in elraglusib combination arms demonstrated deep and durable responses, with ongoing biomarker analyses evaluating features associated with long-term benefit.
The combination was generally well tolerated. Grade 3 or higher treatment-related adverse events occurred in 34.7% of patients, with the most common being diarrhea, fatigue, hypokalemia, and decreased platelet count, a profile consistent with the known toxicities of FOLFIRINOX, further supporting the tolerability of elraglusib.
