SUZHOU, China, and ROCKVILLE, Md., Nov. 2, 2023 /PRNewswire/ -- Ascentage Pharma (6855.HK), a global biopharmaceutical company engaged in developing novel therapies for cancer, chronic hepatitis B (CHB), and age-related diseases, announced today that results from three clinical studies of lisaftoclax (APG-2575), a key candidate drug in the Company's pipeline, have been selected for presentations at the 65th American Society of Hematology (ASH) Annual Meeting, marking the second consecutive year in which clinical results of lisaftoclax were selected. This year, results from multiple clinical studies on two of Ascentage Pharma's lead drug candidates (olverembatinib and lisaftoclax) have been selected for presentations at the ASH Annual Meeting. Developed by Ascentage Pharma, lisaftoclax is an orally available Bcl-2 inhibitor with a wide therapeutic window in multiple hematologic malignancies and solid tumors. The investigational clinical data of lisaftoclax in patients with chronic lymphocytic leukemia (CLL), to be presented at the ASH Annual Meeting this year, once again demonstrate the drug's efficacy and favorable tolerability in patients with CLL who were heavily pretreated and had prior exposure to BTK inhibitors. In two other abstracts on lisaftoclax, results were disclosed from clinical studies of the drug as a single agent and in combination regimens in multiple hematologic malignancies, including relapsed/refractory (R/R) multiple myeloma (MM) and acute myeloid leukemia (AML). The ASH Annual Meeting is one of the largest gatherings of the international hematology community, bringing together the latest and most cutting-edge scientific research in the pathogenesis and clinical treatment of hematologic diseases. The 65th ASH Annual Meeting will take place on December 9-12, 2023, both online and in-person, in San Diego, CA (United States). "Lisaftoclax is the first Bcl-2 inhibitor in China and the second globally that has demonstrated promising efficacy. Clinical results to be presented at the ASH Annual Meeting this year further validate the drug's potential as an alternative treatment option for a number of hematologic malignancies, including R/R CLL," said Dr. Yifan Zhai, Chief Medical Officer of Ascentage Pharma. "In addition, we will also present data of a few more clinical studies that will underscore our broad progress in new drug discovery and clinical development. Moving forward, we will continue to expeditiously advance our clinical development programs globally for the benefit of patients in China and around the world."

Chronic Lymphocytic Leukemia: Clinical and Epidemiological: Poster I Time : Saturday, December 9, 2023, 5:30 PM - 7:30 PM (Pacific Time) / Sunday, December 10, 2023, 9:30 AM – 11:30 AM (Beijing Time) Highlights: This abstract reported updated data from long-term follow-ups in two Phase 1b/2 studies of lisaftoclax (APG-2575-CN001 [NCT03913949] and APG-2575-CC101 [NCT04494503]) in patients with CLL. In the 2 studies, lisaftoclax was administered orally once daily in 28-day cycles, in 100 mg, 200 mg, 400 mg, 600 mg, and 800 mg dose cohorts. Under close monitoring for prevention and early detection of tumor lysis syndrome (TLS), patients were treated (with a daily dose ramp-up schedule) until disease progression, intolerable toxicity, death, or any other reason for termination. As of April 27, 2023, a total of 47 patients with CLL were enrolled. The median (range) duration of follow-up was 14.06 (0.70-30.2) months. The median (range) age was 58 (34-80) years. At enrolment, 53.2% of patients were in Rai stage III/IV, and 48.9% of patients were in Binet stage C. 44.7% of patients had received ≥3 lines of treatment; 66.0% of patients had received ≥2 lines of treatment; 23.4% of patients were treated with Bruton tyrosine kinase inhibitors (BTKis); and 55.3% were treated with a CD20 monoclonal antibody. 68.1% (32) of patients discontinued the study due to disease progression (51.1%), consent withdrawal (6.4%), adverse events (AEs) (2.1%), investigator's decision (2.1%), poor compliance (2.1%), protocol deviation (2.1%), and other reasons (2.1%). The overall response rate (ORR) in patients with CLL was 73.3% (33/45), and the complete response (CR)/incomplete hematological recovery (Cri) rate was 24.4% (11/45). In total, 76.6% (36) of patients experienced grade ≥3 treatment-emergent adverse events (TEAEs); 27.7% (13) experienced serious AEs (SAEs). Treatment-related adverse events (TRAEs) were observed in 95.7% (45) of patients, of whom 68.1% (32) experienced grade ≥3 TRAEs and 14.9% (7) experienced SAEs. One incident of TLS was reported. Conclusions: Lisaftoclax demonstrated significant efficacy and favorable tolerability in patients with CLL who were heavily pretreated and had prior exposure to BTKis. Safety and Efficacy of Lisaftoclax (APG-2575), a Novel BCL-2 Inhibitor (BCL-2i), in Relapsed or Refractory (R/R) or Treatment-Naïve (TN) Patients (Pts) with Acute Myeloid leukemia (AML), Myelodysplastic Syndrome (MDS), or Other Myeloid Neoplasms Format: Poster Presentation Abstract: #2925 Session: 616. Acute Myeloid Leukemias: Investigational Therapies, Excluding Transplantation and Cellular Immunotherapies: Poster II Time : December 10, 2023, Sunday, 6:00 PM – 8:00 PM (Pacific Time) / December 11, 2023, Monday, 10:00 AM – 12:00 PM (Beijing Time) Highlights: This multicenter, open-label, Phase 1 study in China evaluated the efficacy and safety of lisaftoclax alone or combined with azacitidine (AZA) or homoharringtonine (HHT) in patients with treatment-naïve or R/R AML, MDS, or other myeloid neoplasms. Trial design: In part one, lisaftoclax as a single agent was orally administered once daily at 200, 400, 600, or 800 mg, using a "3+3" dose escalation design. In part two, patients with R/R AML, mixed-phenotype acute leukemia (MPAL), blastic plasmacytoid dendritic cell neoplasm (BPDCN), or chronic myelomonocytic leukemia (CMML) were enrolled in Cohorts A, B, and C; while patients with higher-risk MDS were enrolled in Cohort D; and older or chemotherapy-ineligible (unfit) patients with treatment-naïve AML were enrolled in Cohort E. Lisaftoclax was administered orally once daily in 28-day cycles (or 14-day cycles for patients with MDS). A daily ramp-up schedule was adopted to prevent TLS. Cohort A was treated with lisaftoclax combined with low-dose HHT (1 mg daily on days [d] 1-14); Cohort B was treated with lisaftoclax combined with standard-dose HHT (2 mg/m2 daily on d1-7); Cohort C, D, E were treated with lisaftoclax combined with AZA (75 mg/m2 daily on d1-7). Dose-limiting toxicity (DLT) was assessed during the first cycle. As of July 19, 2023, a total of 115 patients were enrolled, including 89 patients with AML (64 R/R; 25 TN older/unfit), 22 with MDS (7 R/R MDS; 15 TN MDS), 2 MPAL, 1 CMML, and 1 BPDCN. A total of 13 patients received lisaftoclax monotherapy and 102 patients received combination regimens. Efficacy results: In patients treated with lisaftoclax monotherapy, the ORR and composite remission rate (CRc=complete remission [CR] + CR with incomplete blood count recovery [CRi]) were each 8.3% (1/12). Lisaftoclax at 600 mg and 800 mg were chosen as exploratory doses for combination therapies. Among the 21 efficacy evaluable patients with TN AML in Cohort E, the ORR and CRc were 71.4% and 47.6%, respectively. Among the 36 efficacy evaluable patients with R/R AML or myeloid neoplasm in Cohort C, the ORR and CRc were 75.0% and 44.4%, respectively. The progression-free survival (PFS) was 10.22 months. Among patients in Cohort B, the ORR and CRc were both 75.0%. Among patients in Cohort D, the ORR was 70.0%, the CR/marrow CR rate was 60.0%。 Safety results: Common TEAEs included hematologic toxicity, electrolyte imbalances, and diarrhea. No TLS was reported during the study and dose-limiting toxicities (DLTs; pneumonia, respiratory failure, and heart failure) were observed in 1 patient in Cohort C. 13 patients who received lisaftoclax monotherapy experienced TEAEs and grade ≥3 TEAEs, and 4 (30.8%) patients experienced SAEs. In patients treated with lisaftoclax combined with HHT, 12 (85.7%) experienced TEAEs and grade ≥3 TEAEs, and 2 (14.3%) experienced SAEs. In the 75 patients treated with lisaftoclax combined with AZA, 100% of patients experienced TEAEs, including 55 (73.3%) who experienced grade ≥3 TEAEs and 18 (24.0%) SAEs. Increased systemic exposure of lisaftoclax was discerned as the dosage escalated from 200 mg to 800 mg. Compared to lisaftoclax monotherapy, no significant difference was observed in the pharmacokinetic profile of lisaftoclax combined with AZA or HHT. Conclusions: Lisaftoclax, in monotherapy or combination regimens, showed encouraging efficacy and favorable tolerability profiles in patients with R/R AML or MDS and older/unfit patients with TN AML. First Report on the Effects of Lisaftoclax (APG-2575 ） in Combination with Novel Therapeutic Regimens in Patients with Relapsed or Refractory Multiple Myeloma (R/R MM ） or Immunoglobulin Light-Chain (Amyloid Light-Chain [AL] ） Amyloidosis Format: Poster Presentation Abstract: #2016 Session: 653. Multiple Myeloma: Prospective Therapeutic Trials: Poster I Time: December 9, 2023, Saturday, 5:30 PM – 7:30 PM (Pacific Time) / December 10, 2023, Sunday, 9:30 AM – 11:30 AM (Beijing Time) Highlights: This multicenter study was designed to evaluate the safety and efficacy of lisaftoclax combination regimens in patients with R/R MM or R/R AL amyloidosis. This study has three treatment arms that included Arm A: lisaftoclax combined with pomalidomide and dexamethasone in patients with R/R MM; Arm B: lisaftoclax combined with daratumumab, lenalidomide, and dexamethasone in patients with R/R MM; and Arm C: lisaftoclax combined with pomalidomide and dexamethasone in patients with R/R amyloidosis. Lisaftoclax was administered orally once daily (QD) at 5 dose levels (400 mg, 600 mg, 800 mg, 1,000 mg, and 1,200 mg) without ramp-up in 28-day cycles. Pomalidomide, daratumumab, and lenalidomide were administered per label use. Dexamethasone 40 mg (20 mg for patients aged >75 years) was administered on Days 1, 8, 15, and 22 of 28-day cycles. As of July 3, 2023, a total of 30 patients were enrolled. Among them, 22, 3, and 5 patients were enrolled into Arms A, B, and C, respectively. 66.7% of patients were male and the median (range) age was 70.5 (24-88) years. All patients were previously exposed to multiple lines of treatment, with a median (range) line of prior therapies of 4 (1-19). 18 patients were triple-class-exposed, including 7 who had received pomalidomide and 3 who harbored the t(11;14) chromosomal abnormality. Safety results: A total of 19 patients experienced lisaftoclax treatment related AEs, including nausea (16.7%), neutropenia (16.7%); thrombocytopenia, leukopenia, abdominal distension, constipation, or diarrhea (6.7% each). A total of 7 patients experienced grade ≥3 TRAEs, including neutropenia (10.0%), febrile neutropenia (3.3%), iron deficiency anemia (3.3%), thrombocytopenia (3.3%), prolonged electrocardiogram QT interval (3.3%), and acute kidney injury (3.3%). Two patients experienced lisaftoclax-related SAEs, including 1 acute kidney injury and 1 febrile neutropenia. Efficacy results: In Arm A, 21 patients with R/R MM were efficacy evaluable, with an ORR (partial response [PR] + very good partial response [VGPR]) of 66.7%. In Arm B, 1 patient with R/R MM achieved PR and another achieved VGPR. In Arm C, 3 patients with R/R amyloidosis achieved a hematologic VGPR. The ORR was 60% and 1 patient experience organ function improvement. Conclusions: Lisaftoclax combination regimens were well tolerated and demonstrated potent antitumor activity in patients with R/R MM and R/R amyloidosis. * Lisaftoclax (APG-2575) is an investigational drug that has not been approved in any country and region.

About Epcoritamab Epcoritamab is an investigational IgG1-bispecific antibody created using Genmab's proprietary DuoBody technology. Genmab's DuoBody-CD3 technology is designed to direct cytotoxic T cells selectively to elicit an immune response towards target cell types. Epcoritamab is designed to simultaneously bind to CD3 on T cells and CD20 on B-cells and induces T cell mediated killing of CD20+ cells.i Epcoritamab was developed with selective, silencing mutations that may limit systemic, non-specific activity.ii CD20 is expressed on B-cells and a clinically validated therapeutic target in many B-cell malignancies, including diffuse large B-cell lymphoma, follicular lymphoma, mantle cell lymphoma and chronic lymphocytic leukemia.iii,iv Epcoritamab is being co-developed by Genmab and AbbVie as part of the companies’ broad oncology collaboration. About Tisotumab Vedotin Tisotumab vedotin-tftv (TIVDAK®) is an antibody-drug conjugate (ADC) composed of Genmab’s human monoclonal antibody directed to tissue factor (TF) and Seagen’s ADC technology that utilizes a protease-cleavable linker that covalently attaches the microtubule-disrupting agent monomethyl auristatin E (MMAE) to the antibody. Nonclinical data suggests that the anticancer activity of tisotumab vedotin is due to the binding of the ADC to TF expressing cancer cells, followed by internalization of the ADC-TF complex, and release of MMAE via proteolytic cleavage. MMAE disrupts the microtubule network of actively dividing cells, leading to cell cycle arrest and apoptotic cell death. In vitro, tisotumab vedotin also mediates antibody-dependent cellular phagocytosis and antibody-dependent cellular cytotoxicity. In September 2021, the U.S. Food and Drug Administration granted accelerated approval for tisotumab vedotin-tftv (TIVDAK) in adult patients with previously treated recurrent or metastatic cervical cancer with disease progression on or after chemotherapy, making it the first and only approved ADC for these patients. The ongoing clinical trial InnovaTV 301, an open label, randomized, global trial, is intended as the confirmatory trial for use in verifying and describing the clinical benefit and as support for US and global regulatory applications. TIVDAK (tisotumab vedotin-tftv) U.S Indication & Important Safety Information TIVDAK is indicated for the treatment of adult patients with recurrent or metastatic cervical cancer with disease progression on or after chemotherapy. This indication is approved under accelerated approval based on tumor response rate and durability of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trials. Important Safety Information BOXED WARNING: OCULAR TOXICITY TIVDAK caused changes in the corneal epithelium and conjunctiva resulting in changes in vision, including severe vision loss, and corneal ulceration. Conduct an ophthalmic exam at baseline, prior to each dose, and as clinically indicated. Adhere to premedication and required eye care before, during, and after infusion. Withhold TIVDAK until improvement and resume, reduce the dose, or permanently discontinue, based on severity. Warnings and Precautions Ocular Adverse Reactions occurred in 60% of patients with cervical cancer treated with TIVDAK across clinical trials. The most common were conjunctival adverse reactions (40%), dry eye (29%), corneal adverse reactions (21%), and blepharitis (8%). Grade 3 ocular adverse reactions occurred in 3.8 % of patients, including severe ulcerative keratitis in 3.2% of patients. One patient experienced ulcerative keratitis with perforation requiring corneal transplantation. Cases of symblepharon were reported in patients with other tumor types treated with TIVDAK at the recommended dose. In innovaTV 204, 4% of patients experienced visual acuity changes to 20/50 or worse including 1% of patients who experienced a visual acuity change to 20/200. Of the patients who experienced decreased visual acuity to 20/50 or worse, 75% resolved, including the patient who experienced decreased visual acuity to 20/200. Refer patients to an eye care provider for an ophthalmic exam including visual acuity and slit lamp exam at baseline, prior to each dose, and as clinically indicated. Adhere to premedication and required eye care to reduce the risk of ocular adverse reactions. Promptly refer patients to an eye care provider for any new or worsening ocular signs and symptoms. Withhold dose, reduce the dose, or permanently discontinue TIVDAK based on the severity of the adverse reaction. Peripheral Neuropathy (PN) occurred in 42% of cervical cancer patients treated with TIVDAK across clinical trials; 8% of patients experienced Grade 3 PN. PN adverse reactions included peripheral neuropathy (20%), peripheral sensory neuropathy (11%), peripheral sensorimotor neuropathy (5%), motor neuropathy (3%), muscular weakness (3%), and demyelinating peripheral polyneuropathy (1%). One patient with another tumor type treated with TIVDAK at the recommended dose developed Guillain- Barre syndrome. Monitor patients for signs and symptoms of neuropathy. For new or worsening PN, withhold, dose reduce, or permanently discontinue TIVDAK based on the severity of PN. Hemorrhage occurred in 62% of cervical cancer patients treated with TIVDAK across clinical trials. The most common all grade hemorrhage adverse reactions were epistaxis (44%), hematuria (10%), and vaginal hemorrhage (10%). Grade 3 hemorrhage occurred in 5% of patients. Monitor patients for signs and symptoms of hemorrhage. For patients experiencing pulmonary or CNS hemorrhage, permanently discontinue TIVDAK. For Grade ≥2 hemorrhage in any other location, withhold until bleeding has resolved, blood hemoglobin is stable, there is no bleeding diathesis that could increase the risk of continuing therapy, and there is no anatomical or pathologic condition that can increase the risk of hemorrhage recurrence. After resolution, either resume treatment or permanently discontinue TIVDAK. Pneumonitis: Severe, life-threatening, or fatal pneumonitis can occur in patients treated with antibody-drug conjugates containing vedotin, including TIVDAK. Among patients with cervical cancer treated with TIVDAK across clinical trials, 2 patients (1.3%) experienced pneumonitis, including 1 patient who had a fatal outcome. Monitor patients for pulmonary symptoms of pneumonitis. Infectious, neoplastic, and other causes for symptoms should be excluded through appropriate investigations. Withhold TIVDAK for patients who develop persistent or recurrent Grade 2 pneumonitis and consider dose reduction. Permanently discontinue TIVDAK in all patients with Grade 3 or 4 pneumonitis. Embryo-Fetal Toxicity: TIVDAK can cause fetal harm when administered to a pregnant woman. Advise patients of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with TIVDAK and for 2 months after the last dose. Advise male patients with female partners of reproductive potential to use effective contraception during treatment with TIVDAK and for 4 months after the last dose. Adverse Reactions In the innovaTV 204 clinical trial (n=101), serious adverse reactions occurred in 43% of patients; the most common (≥3%) were ileus (6%), hemorrhage (5%), pneumonia (4%), PN, sepsis, constipation, and pyrexia (each 3%). Fatal adverse reactions occurred in 4% of patients who received TIVDAK, including septic shock, pneumonitis, sudden death, and multisystem organ failure (each 1%). Adverse reactions leading to permanent discontinuation occurred in 13% of patients receiving TIVDAK; the most common (≥3%) were PN (5%) and corneal adverse reactions (4%). Adverse reactions leading to dose interruption occurred in 47% of patients; the most common (≥3%) were PN (8%), conjunctival adverse reactions (4%), and hemorrhage (4%). Adverse reactions leading to dose reduction occurred in 23% of patients; the most common (≥3%) were conjunctival adverse reactions (9%) and corneal adverse reactions (8%). The most common (≥25%) adverse reactions, including laboratory abnormalities, were hemoglobin decreased (52%), fatigue (50%), lymphocytes decreased (42%), nausea (41%), PN (39%), alopecia (39%), epistaxis (39%), conjunctival adverse reactions (37%), hemorrhage (32%), leukocytes decreased (30%), creatinine increased (29%), dry eye (29%), prothrombin international normalized ratio increased (26%), activated partial thromboplastin time prolonged (26%), diarrhea (25%), and rash (25%). Drug interactions Strong CYP3A4 Inhibitors: Concomitant use with strong CYP3A4 inhibitors may increase unconjugated monomethyl auristatin E (MMAE) exposure, which may increase the risk of TIVDAK adverse reactions. Closely monitor patients for TIVDAK adverse reactions. Use in Specific Populations Moderate or Severe Hepatic Impairment: MMAE exposure and adverse reactions are increased. Avoid use. Lactation: Advise lactating women not to breastfeed during TIVDAK treatment and for at least 3 weeks after the last dose.
