ROCKVILLE, Md. and SUZHOU, China, April 7, 2024 /PRNewswire/ -- Ascentage Pharma (6855.HK), a global biopharmaceutical company engaged in developing novel therapies for cancer, age-related diseases, and chronic hepatitis B (CHB), announced today that it releases the latest results from three preclinical studies of its novel drug candidates olverembatinib, MDM2-p53 inhibitor alrizomadlin (R&D Code: APG-115), FAK/ALK/ROS1 tyrosine kinase inhibitor APG-2449, and embryonic ectoderm development (EED) inhibitor APG-5918, at the 2024 American Association of Cancer Research Annual Meeting (AACR 2024). This year's AACR annual meeting will be held from April 5-10 2024, in San Diego, California, USA. "We are pleased to present the preclinical research data of four assets in our pipeline at the AACR 2024. The results provided essential support for the potential clinical development and therapeutic combinations of these compounds in SDH-deficient neoplasms, prostate cancer, and ovarian cancer," said Dr. Yifan Zhai, Chief Medical Officer of Ascentage Pharma. "Moving forward, we will continue to advance these programs toward the clinical stage in order to bring more treatment options to patients in need." The details of these three preclinical studies are as follows: Olverembatinib, a novel multikinase inhibitor, demonstrates superior antitumor activity in succinate dehydrogenase (SDH)-deficient neoplasms Abstract#: 1971 Time: Monday April 8, 2024, 9:00 AM - 12:30 PM (Pacific Time) Introduction: Succinate dehydrogenase (SDH) – deficient (dSDH) neoplasms are identified by the loss of immunohistochemical expression of SDHB due to the bi-allelic inactivation of any of the four components of mitochondrial SDH complex (SDH A-D). Succinate accumulation, due to SDH deficiency, is involved in tumorigenesis of different types of cancers including gastrointestinal stromal tumor (GIST), paraganglioma, pheochromocytoma, renal cell carcinoma, pituitary adenomas, and pancreatic neuroendocrine tumors. The prognosis of patients with dSDH neoplasia, especially GIST, is poor and approved tyrosine kinase inhibitors (TKIs) have limited efficacy. There is a high unmet medical need for these patients. Olverembatinib, a novel multi-kinase inhibitor, targets a broad spectrum of kinases and has demonstrated promising efficacy in dSDH GIST patients in an ongoing phase I clinical trial. In this study, we assessed antitumor effects of olverembatinib in preclinical models of dSDH cancers and dSDH GIST primary tumor cells, and explored potential mechanisms of action. Conclusions: Olverembatinib showed superior anti-tumor activity in dSDH cell lines in vitro and human dSDH GIST primary tumor cells ex vivo. Olverembatinib, as a multi-target kinase inhibitor, exerted antitumor effects by modulating multiple signaling pathways including hypoxia, angiogenesis, apoptosis, proliferation, and survival, which are involved in tumorigenesis of dSDH cancers. Olverembatinib demonstrated more potent in vivo antitumor activity in mice bearing PC12#5F7 (SDHB KD) xenograft tumors than other TKIs. Western blot analysis in tumor tissues collected from mice further confirmed the modulation of the signal pathways by olverembatinib observed in cell lines. In summary, the results provide a rationale for future clinical development of olverembatinib in dSDH cancers. Embryonic ectoderm development (EED) inhibitor APG-5918 (EEDi-5273) and MDM2 inhibitor alrizomadlin (APG-115) synergistically inhibit tumor growth in preclinical models of prostate cancer (PCa) Abstract#: 3223 Time: Monday April 8, 2024, 1:30 PM - 5:00 PM (Pacific Time) Introduction: Prostate cancer (PCa) is one of the most frequently diagnosed malignancies among elderly males. Androgen deprivation therapy (ADT) with or without androgen receptor (AR) inhibitors is widely used as initial treatment for advanced PCa. However, most ADT-treated patients eventually develop castration-resistant prostate cancer (CRPC), which is in urgent need of novel therapies. Polycomb repressive complexes 2 (PRC2) dysregulation is common in PCa and correlates with poor prognosis. PRC2 mediates histone H3 lysine 27 tri-methylation (H3K27me3), a repressive epigenetic marker for gene transcription. embryonic ectoderm development (EED), a PRC2 core component, is crucial for histone methyltransferase activity through direct binding to H3K27me3. MDM2, a negative regulator of the tumor suppressor p53, is frequently amplified or overexpressed in PCa, and associated with poor clinical outcomes and metastasis. The aim of this study was to evaluate antitumor activity and molecular mechanisms of the investigational, clinical-stage EED inhibitor APG-5918/EEDi-5273 and MDM2 selective inhibitor alrizomadlin (APG-115) in PCa preclinical models Conclusions: In PCa preclinical models, the combination of APG-5918 and alrizomadlin synergistically inhibited cellular proliferation and induced cellular apoptosis. APG-5918 in combination with alrizomadlin synergistically enhanced antitumor activity in PCa xenograft models in vivo. Mechanistically, PD analysis revealed that APG-5918 downregulated the oncogenic DNA methylation factors (UHRF1, DNMT1) and histone methylation marker H3K27me3. Alrizomadlin markedly downregulated UHRF1 and DNMT1, and upregulated p53 and p21 expression. Combined treatment further enhanced downregulation of DNMT1, UHRF1, cell cycle pathway proteins (pRb, CDK6), antiapoptotic protein MCL-1, and synergistically increased cleavage of PARP-1, a marker of apoptosis. Therefore, the findings provide a scientific rationale for future clinical development of APG-5918 and alrizomadlin to treat patients with PCa. APG-2449, a novel focal adhesion kinase (FAK) inhibitor, inhibits metastasis and enhances the antitumor efficacy of PEGylated liposome doxorubicin (PLD) in epithelial ovarian cancer (EOC) Abstract#: 4569 Time: Tuesday April 9, 2024, 9:00 AM - 12:30 PM (Pacific Time) Introduction: Ovarian cancer is among the leading causes of cancer-related death in women, and most cases are diagnosed at later stages with distant metastasis. FAK overexpression or activation occurs in a substantial proportion of epithelial ovarian cancers (EOCs) and is predictive of poor clinical outcomes. FAK plays an important role in cell migration and chemoresistance, rendering FAK inhibition a promising treatment approach to reduce metastasis of tumor cells and sensitize them to chemotherapy. FAK is therefore emerging as a potential treatment target. The aim of this study was to evaluate the antitumor efficacy of investigational APG-2449, a novel FAK inhibitor, combined with PLD, a commonly used chemotherapy, in relapsed or refractory ovarian cancer. Conclusions: APG-2449 combined with doxorubicin showed synergistic antiproliferative effects in both platinum-resistant and platinum-sensitive ovarian cancer cell lines. FAK inhibition via APG-2449 alone attenuated migration of ovarian cancer cells in a dose-dependent manner. APG-2449 in combination with PLD showed enhanced antitumor activity in platinum-resistant OVCAR-3 ovarian cancer CDX model. The combination regimen prolonged ascites-free and survival times in the ID8-Luc peritoneal syngeneic model. These promising results support the future clinical development of this combination treatment for ovarian cancer.

Expanded indication for this one-time infusion will provide more patients with a potential period away from their multiple myeloma treatment as early as first relapse Approval is based on results from the Phase 3 CARTITUDE-4 study, in which treatment with CARVYKTI® in 1-3 prior lines of therapy reduced the risk of disease progression or death by 59 percent compared to standard therapies HORSHAM, Pa., April 5, 2024 /PRNewswire/ -- Johnson & Johnson (NYSE: JNJ) announced today that the U.S. Food and Drug Administration (FDA) has approved CARVYKTI® (ciltacabtagene autoleucel; cilta-cel) for the treatment of adult patients with relapsed or refractory multiple myeloma who have received at least one prior line of therapy, including a proteasome inhibitor and an immunomodulatory agent, and are refractory to lenalidomide.1 With this approval, CARVYKTI® becomes the first and only B-cell maturation antigen (BCMA)-targeted therapy approved for the treatment of patients with multiple myeloma as early as first relapse. FDA approval is based on positive results from the Phase 3 CARTITUDE-4 study, which demonstrated that the earlier use of CARVYKTI® reduced the risk of disease progression or death by 59 percent compared to standard therapies—pomalidomide, bortezomib and dexamethasone (PVd) or daratumumab, pomalidomide and dexamethasone (DPd)—in adults with relapsed and lenalidomide-refractory multiple myeloma who received one to three prior lines of therapy.1 The study, which was presented at the 2023 American Society of Clinical Oncology (ASCO) Annual Meeting and published in The New England Journal of Medicine, also included and reported key secondary results such as overall response (OR) and overall survival (OS).1 "CARVYKTI demonstrated remarkable efficacy as a personalized, one-time infusion in the earlier treatment of relapsed/refractory multiple myeloma as shown through the CARTITUDE-4 study results," said Binod Dhakal, M.D., Associate Professor, Medical College of Wisconsin, Division of Hematology and Oncology.* "With this approval, I'm excited for patients who may have the opportunity for a treatment-free period for their multiple myeloma as early as first relapse, with the hope of eliminating the burden of having to be on continuous treatment while living with this challenging disease." More than 35,000 estimated new cases of multiple myeloma, an incurable blood cancer, will be diagnosed in 2024 in the United States.2 Real-world studies show that only an estimated 15 percent of patients initially diagnosed with multiple myeloma are able to start a 5th line of therapy.3 With this new indication, more patients will be able to access this innovative treatment. "This milestone underscores our commitment to improve outcomes for patients and transform the treatment of multiple myeloma with CARVYKTI," said Jordan Schecter, M.D., Vice President, Disease Area Leader, Multiple Myeloma, Johnson & Johnson Innovative Medicine. "We are proud to bring an important, highly effective immunotherapy that has demonstrated a favorable benefit/risk profile to physicians and patients for the earlier treatment of relapsed/refractory multiple myeloma, and we look forward to building on this latest milestone as we continue to focus on our ultimate goal of delivering a cure for multiple myeloma." CARVYKTI® is a cell therapy that works by harnessing a patient's immune system, or T cells, to fight the disease. Treatment requires extensive training, preparation, and certification to ensure a positive experience for patients. Since initial approval in February 2022, Johnson & Johnson has made significant advances in manufacturing to rapidly scale CARVYKTI® production. "We understand the urgency for patients in need of CARVYKTI, and we have been making considerable progress in increasing supply and availability in anticipation of this milestone approval," said Tyrone Brewer, President, U.S. Hematology, Johnson & Johnson Innovative Medicine. "We more than doubled manufacturing of CARVYKTI in 2023, we are striving to double again in 2024, and we will continue to invest in our capacity so we can provide this critical therapy to as many patients as possible." The safety profile for CARVYKTI® includes a boxed warning for Cytokine Release Syndrome (CRS), Immune Effector Cell-Associated Neurotoxicity Syndrome (ICANS), Parkinsonism and Guillain-Barre syndrome and their associated complications, Hemophagocytic Lymphohistiocytosis/Macrophage Activation Syndrome (HLH/MAS), Prolonged and Recurrent Cytopenias and Secondary Malignancies including myelodysplastic syndrome, acute myeloid leukemia and T-cell malignancies.1 Warnings and Precautions include Increased Early Mortality, Hypogammaglobulinemia, Infections, Hypersensitivity Reactions and Effects on Ability to Drive and Use Machines.1 The most common nonlaboratory adverse reactions (incidence greater than 20 percent) are pyrexia, cytokine release syndrome, hypogammaglobulinemia, hypotension, musculoskeletal pain, fatigue, infections-pathogen unspecified, cough, chills, diarrhea, nausea, encephalopathy, decreased appetite, upper respiratory tract infection, headache, tachycardia, dizziness, dyspnea, edema, viral infections, coagulopathy, constipation, and vomiting.1The most common Grade 3 or 4 laboratory adverse reactions (incidence greater than or equal to 50 percent) include lymphopenia, neutropenia, white blood cell decreased, thrombocytopenia, and anemia.1 About CARTITUDE-4 CARTITUDE-4 (NCT04181827) is the first international, randomized, open-label Phase 3 study evaluating the efficacy and safety of cilta-cel versus pomalidomide, bortezomib and dexamethasone (PVd) or daratumumab, pomalidomide and dexamethasone (DPd) in adult patients with relapsed and lenalidomide-refractory multiple myeloma who received one to three prior lines of therapy.4 Results were presented at the 2023 American Society of Clinical Oncology (ASCO) Annual Meeting and published in The New England Journal of Medicine. About CARVYKTI ® (ciltacabtagene autoleucel; cilta-cel) CARVYKTI® (cilta-cel) received U.S. Food and Drug Administration approval in February 2022 for the treatment of adults with relapsed or refractory multiple myeloma after four or more prior lines of therapy, including a proteasome inhibitor, an immunomodulatory agent, and an anti-CD38 monoclonal antibody.1 CARVYKTI® is now approved in the U.S. for the second-line treatment of adult patients with relapsed or refractory myeloma who have received at least one prior line of therapy including a proteasome inhibitor, an immunomodulatory agent, and who are refractory to lenalidomide. In addition to a unanimous (11 to 0) FDA Oncologic Drugs Advisory Committee (ODAC) recommendation in support of this new indication, in March 2024, the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) recommended the approval of a Type II variation for CARVYKTI® for the treatment of adults with relapsed and refractory multiple myeloma who have received at least one prior therapy, including an immunomodulatory agent and a proteasome inhibitor, have demonstrated disease progression on the last therapy, and are refractory to lenalidomide. In September 2022, Japan's Ministry of Health, Labour and Welfare (MHLW) approved CARVYKTI® for the treatment of adults with relapsed or refractory multiple myeloma in patients that have no history of CAR-positive T cell infusion therapy targeting BCMA and who have received three or more lines of therapies, including an immunomodulatory agent, a proteasome inhibitor and an anti-CD38 monoclonal antibody, and in whom multiple myeloma has not responded to or has relapsed following the most recent therapy. CARVYKTI® is a BCMA-directed, genetically modified autologous T-cell immunotherapy, which involves reprogramming a patient's own T-cells with a transgene encoding chimeric antigen receptor (CAR) that directs the CAR positive T cells to eliminate cells that express BCMA. BCMA is primarily expressed on the surface of malignant multiple myeloma B-lineage cells, as well as late-stage B cells and plasma cells. The CARVYKTI® CAR protein features two BCMA-targeting single domains 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. In December 2017, Janssen Biotech, Inc., a Johnson & Johnson company, entered into an exclusive worldwide license and collaboration agreement with Legend Biotech USA, Inc. to develop and commercialize CARVYKTI®.

About Multiple Myeloma Multiple myeloma is an incurable blood cancer that affects a type of white blood cell called plasma cells, which are found in the bone marrow.5 In multiple myeloma, these plasma cells change, spread rapidly and replace normal cells in the bone marrow with tumors.6 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.2 While some people diagnosed with multiple myeloma initially have no symptoms, most patients are diagnosed due to symptoms that can include bone fracture or pain, low red blood cell counts, tiredness, high calcium levels, kidney problems, or infections.7,8 INDICATIONS AND USAGE CARVYKTI® (ciltacabtagene autoleucel) is a B-cell maturation antigen (BCMA)-directed genetically modified autologous T cell immunotherapy indicated for the treatment of adult patients with relapsed or refractory multiple myeloma, who have received at least 1 prior line of therapy, including a proteasome inhibitor and an immunomodulatory agent, and are refractory to lenalidomide. IMPORTANT SAFETY INFORMATION 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 (ASCT 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. Ensure that a minimum of two 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 one dose of corticosteroids for treatment of CRS. Monitor patients at least daily for 10 days following CARVYKTI® infusion at a REMS-certified healthcare facility for signs and symptoms of CRS. Monitor patients for signs or symptoms of CRS for at least 4 weeks after infusion. At the first sign of CRS, 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 cut off. 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 10 days following CARVYKTI® infusion at the REMS-certified healthcare facility for signs and symptoms of ICANS. Rule out other causes of ICANS symptoms. Monitor patients for signs or symptoms of ICANS for at least 4 weeks after infusion and treat promptly. Neurologic toxicity should be managed with supportive care and/or corticosteroids as needed. 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 cut off. 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 cut off. 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 cut off. 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. CARVYKTI® REMS: Because of the risk of CRS and neurologic toxicities, CARVYKTI® is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the CARVYKTI® REMS. Further information is available at or 1-844-672-0067. 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. 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 500mg/dl after infusion in 93% (265/285) of patients. Hypogammaglobulinemia either as an adverse reaction or laboratory IgG level below 500mg/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 ≤Grade 2. 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. 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 life-long for secondary malignancies.

SHANGHAI and HONG KONG, April 5, 2024 /PRNewswire/ -- Antengene Corporation Limited ( " Antengene " , SEHK: 6996.HK), a leading innovative, commercial-stage global biopharmaceutical company dedicated to discovering, developing and commercializing first-in-class and/or best-in-class medicines for cancer, today announced the presentation of four preclinical posters at the 2024 American Association for Cancer Research Annual Meeting (AACR 2024), taking place from April 5th to April 10th at the San Diego Convention Center in San Diego, California, the United States. The posters showcased four of Antengene's high-potential emerging programs, including ATG-042, tracking to a H1 2025 IND filing; ATG-022, in Phase II dose expansion studies in China and Australia; AnTenGagerTM platform, Antengene's proprietary T-cell engager (TCE) platform; and ATG-102, which could be the first IND candidate from AnTenGagerTM platform. ATG-042, an oral small molecule MTAPnull-selective PRMT5 inhibitor holding the promise as a best-in-class drug. Study results showed that ATG-042 has the potential to elegantly target tumor cells while sparing healthy cells, with an attractive developability profile. ATG-022 is an Claudin 18.2 antibody-drug conjugate. The detailed updated data of the Claudin 18.2 (CLDN18.2) companion diagnostic antibody candidate for ATG-022 showed that the antibody has higher sensitivity compared to commercially available kits. AnTenGagerTM, Antengene's proprietary TCE platform with the ability to induce target-dependent T-cell activation, has potent anti-tumor effects and lower risk of cytokine release syndrome (CRS). ATG-102, a LILRB4 x CD3 TCE, is being developed for the treatment of acute myeloid leukemia (AML). Details of the posters: ATG-042 (MTAPnull-selective PRMT5 Inhibitor) Title: Preclinical characterization of ATG-042, a novel MTAPnull-selective PRMT5 inhibitor Abstract: 4592 Session Category: Experimental and Molecular Therapeutics Session Title: HDAC and Methyltransferase Inhibitors Date: April 9, 2024 Time: 9:00 AM - 12:30 PM (Pacific Time) 12:00 AM - 3:30 AM, April 10, 2024 (Beijing Time) Location: Poster Section 24 This preclinical study was designed to test the in vitro/in vivo efficacy, and preclinical pharmacokinetic (PK) properties of ATG-042. According to the results, ATG-042 demonstrated a potent and selective inhibitory effect on the proliferation of MTAP knockout cells, showed high permeability, good metabolic stability, a low risk of drug-drug interaction (DDI), and high oral bioavailability. Importantly, ATG-042 demonstrated good brain penetrability. In CDX models, ATG-042 also potently and selectively inhibited tumor growth without inducing weight loss. These data suggest that ATG-042 is an orally administered, MTAPnull-selective PRMT5 inhibitor with potent efficacy against MTAP-null tumors, as well as demonstrating good tolerability and favorable preclinical PK profiles. Companion Diagnostic Antibody for ATG-022 (Claudin 18.2 ADC) Title: Development of a novel companion diagnostic immunohistochemistry antibody for Claudin 18.2-targeted therapies Abstract: 1032 Session Category: Clinical Research Session Title: Diagnostic Biomarkers 1 Date: April 7, 2024 Time: 1:30 PM - 5:00 PM (Pacific Time) 4:30 AM - 8:00 AM, April 8, 2024 (Beijing Time) Location: Poster Section 42 Despite the substantial correlation between the expression of CLDN18.2 and the efficacy of therapies targeting CLDN18.2, no companion diagnostic (CDx) antibodies specific to CLDN18.2 have been approved to date. This poster presents the discovery and validation of a novel, highly sensitive immunohistochemistry (IHC) antibody that selectively identifies CLDN18.2. According these data, the monoclonal antibody (mAb) clone 43F11 showed positive cell surface IHC staining on CLDN18.2-expressing cells following fixation but demonstrated no staining on CLDN18.1-expressing cells. Moreover, the 43F11 antibody accurately identified the expression level of CLDN18.2 in an IHC assay, utilizing tumor tissues and patient-derived xenograft (PDX) samples with predetermined expression levels of CLDN18.2. When compared to the commercially available IHC antibody EPR19202, the 43F11 antibody demonstrated greater sensitivity, enabling positive staining on cancer tissues with significantly lower expression levels of CLDN18.2. These data suggest that the 43F11 antibody possesses superior sensitivity compared to the benchmark antibody and has the potential to serve as an effective patient stratification tool. AnTenGager TM Platform Title: AnTenGagerTM, a novel "2+1" T cell engager platform, enables conditional T cell activation with reduced risk of CRS Abstract: 6343 Session Category: Clinical Research Session Title: Antibodies 2 Date: April 9, 2024 Time: 1:30 PM - 5:00 PM (Pacific Time) 4:30 AM - 8:00 AM, April 10, 2024 (Beijing Time) Location: Poster Section 41 This poster presents an in-depth overview of the design and mechanism of action for the proprietary AnTenGagerTM T cell engager (TCE) platform. These TCEs are specifically designed to produce an anti-cancer effect with a lower risk of systemic CD3 activation and cytokine release syndrome (CRS), potentially paving the way for use in solid tumors. AnTenGagers TCE constructs are designed to induce cytotoxicity by forming a T cell receptor (TCR)-independent immune synapse. AnTenGagers do this by simultaneously binding tumor associated antigens (TAAs) on cancer cells and specific conformational epitopes on CD3+ T-cells. Presented data show that AnTenGagers are able to effectively bind to specific CD3 confirmational epitopes and demonstrate higher cytotoxicity compared to benchmark compounds. AnTenGagers are compatible with a range of TAAs, and that AnTenGagers have improved cytotoxicity compared to benchmark compounds, as demonstrated in cellular assays and a murine myeloma model. Data from the murine models also showed that AnTenGagers resulted in significantly lower concentrations of pro-inflammatory cytokines, further supporting a lower risk of CRS. AnTenGagers also have good "developability" properties based on good stability under stress conditions. Together, these data support the potential for AnTenGagers to be used in solid tumors, based on their ability to simultaneously bind TAAs and specific CD3+ confirmational epitopes, resulting in higher TAA-dependent cytotoxicity compared to benchmarks and the reduced risk of CRS, opening the door to a broad new class of cancer therapies. ATG-102 (LILRB4 x CD3 T Cell Engager) Title: ATG-102, a novel LILRB4 x CD3 T cell engager, targeting two non-overlapping epitopes of LILRB4, for the treatment of monocytic AML Abstract: 2372 Session Category: Clinical Research Session Title: Antibodies 1 Date: April 8, 2024 Time: 9:00 AM - 12:30 PM (Pacific Time) 12:00 AM - 3:30 AM, April 9, 2024 (Beijing Time) Location: Poster Section 38 The use of TCEs to treat AML (acute myeloid leukemia) has been limited the difficulty in identifying specific antigens that are expressed on AML and leukemic stem cells but not normal hematopoietic stem cells. The preferential expression of LILRB4 on M4/M5 subtype acute myeloid leukemia (AML) cells renders it a highly attractive target for the treatment of AML. These data show that an AnTenGagerTM based TCE, which binds to two distinct epitopes of the LILRB4 receptor, can induce potent T-cell dependent cellular cytotoxicity (TDCC) to produce potent anti-tumor efficacy in vitro and in vivo. The poster outlines the design and structural characteristics of ATG-102 comprised of two LILRB4 epitopes and an anti-CD3 single chain fragment variable (scFv) inserted in the hinge region on one of the LILRB4 heavy chains. Characterization data include: -Binding epitope and affinity studies showing that ATG-102 binds to the target TAA epitopes as well as conformational CD3 epitopes. -T cell binding and T-cell dependent cytotoxicity assays show that compared to the benchmark, ATG-102 demonstrated less non-specific T cell binding or activation, whilst inducing more potent TDCC against LILRB4+cells and enhanced in vivo anti-AML efficacy. These data highlight the structural characteristics of ATG-102 and demonstrate potent in vitro and in vivo anti-tumor efficacy which support further clinical evaluation of ATG-102.
