The ASCO (Free ASCO Whitepaper) Annual Meeting showcases cutting-edge research in clinical oncology and advanced cancer therapies and is the world’s largest gathering of the clinical oncology community. This year marks Ascentage Pharma’s ninth consecutive appearance at ASCO (Free ASCO Whitepaper). A total of six studies involving three of the Company’s key assets were selected for presentation, including three rapid oral presentations.

The data presented demonstrated preliminary antitumor activity and a manageable tolerability profile of alrizomadlin in pediatric solid tumors. Results showed that alrizomadlin monotherapy demonstrated initial clinical benefit in pediatric rhabdomyosarcoma (RMS), with one pediatric patient achieving a complete response (CR). In combination with investigational selective Bcl-2 inhibitor lisaftoclax, encouraging antitumor activity was observed, with an objective response rate (ORR) of 23.5% among 17 response-evaluable patients, including one complete response in a patient with Ewing sarcoma and three partial responses (PRs). In terms of safety, alrizomadlin, either as monotherapy or in combination with lisaftoclax, demonstrated a manageable safety profile in pediatric patients with solid tumors.

Alrizomadlin is an orally administered, highly selective MDM2-p53 inhibitor independently developed by Ascentage Pharma. It is the first investigational agent of its class to enter clinical development in China and has global first-in-class potential. By blocking the MDM2-p53 protein-protein interaction, alrizomadlin restores the tumor suppressor activity of p53 and induces apoptosis in tumor cells. Recently, alrizomadlin was officially included by the Center for Drug Evaluation (CDE) of China’s National Medical Products Administration (NMPA) in the Pilot Program for the Support of Anti-tumor Drugs R&D for Kids, also known as the "SPARK Plan," for development in pediatric solid tumors including neuroblastoma, rhabdomyosarcoma, and Ewing sarcoma.

Professor Yizhuo Zhang, principal investigator of the study from the Department of Pediatric Oncology at Sun Yat-sen University Cancer Center, said: "Relapsed/refractory pediatric sarcomas are associated with extremely poor prognosis and substantial unmet medical needs. The data presented at the ASCO (Free ASCO Whitepaper) meeting demonstrated a favorable tolerability profile and promising anti-tumor effect for alrizomadlin both as monotherapy and in combination with lisaftoclax, with the complete response (CR) cases being particularly encouraging. As a key candidate included in the SPARK Plan, alrizomadlin has the potential to become a first-in-class therapy, address unmet medical needs, and bring new hope for long-term survival to pediatric patients."

Professor Yi Zhang, investigator of the study from the Department of Pediatrics at Beijing Tongren Hospital, Capital Medical University, said: "Treatment options for pediatric solid tumors, especially advanced soft-tissue sarcomas, remain very limited. The clinical data generated by the alrizomadlin combination regimen are therefore particularly meaningful. This apoptosis pathway-targeting therapy demonstrated favorable tolerability and encouraging objective response rates, further supporting the therapeutic potential of dual-target combination approaches in refractory pediatric tumors and providing valuable direction for future precision drug development in pediatric oncology."

Yifan Zhai, MD, Chief Medical Officer of Ascentage Pharma, said: "Pediatric solid tumors continue to represent an area of significant unmet medical need. The data presented at ASCO (Free ASCO Whitepaper) mark our first presentation of alrizomadlin clinical data in pediatric solid tumor patients and demonstrated encouraging preliminary clinical benefit and tolerability. Importantly, alrizomadlin has already been included by the CDE in the SPARK Plan for potential development in multiple pediatric solid tumors. The data presented provide initial clinical evidence supporting this development strategy. We will continue to advance the related clinical studies with the goal of bringing new treatment options to pediatric patients in urgent need."

Key highlights from the study presented at the 2026 ASCO (Free ASCO Whitepaper) Annual Meeting are as follows:

Alrizomadlin (APG-115) alone or in combination with Lisaftoclax (APG-2575) for the treatment of pediatric patients with relapsed/metastatic rhabdomyosarcoma (RMS) or other soft-tissue sarcomas (STSs)
Abstract #: 10012
Presentation Type: Rapid Oral Presentation
Session Title: Pediatric Oncology II
First Author: Yizhuo Zhang, MD, Department of Pediatric Oncology, Sun Yat-sen University Cancer Center, State Key Laboratory of Oncology in South China, Collaborative Innovation Center for Cancer Medicine
Key Highlights:

Research Background: This multicenter clinical trial conducted in China evaluated the safety and preliminary efficacy of alrizomadlin (APG-115) as monotherapy or in combination with lisaftoclax in heavily pretreated pediatric patients with relapsed/metastatic RMS, Ewing sarcoma (EWS), neuroblastoma (NB), and other solid tumors.
Efficacy Data: In the monotherapy arm, 1 patient with refractory RMS achieved CR. In the combination arm, among 17 response-evaluable pediatric patients with relapsed/refractory solid tumors, the ORR was 23.5%, including 1 CR in a patient with EWS, as well as PRs in 2 patients with RMS and 1 patient with NB. The disease control rate (DCR) was 70.6%.
Safety Data: No dose-limiting toxicities (DLTs) were observed in either the monotherapy or combination arm. Adverse events were primarily gastrointestinal and hematologic, with few serious adverse events and no treatment-related deaths or discontinuations.
Conclusion: The regimen demonstrated a manageable safety profile and preliminary antitumor activity in pediatric solid tumors, supporting further investigation.

* Alrizomadlin is currently under investigation and has not yet been approved by the US FDA.

The oral presentation of these data is taking place at the 2026 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting being held May 29 – June 2, 2026, in Chicago (Abstract #LBA7000. Session: Oral Abstract Session – Hematologic Malignancies – Lymphoma and Chronic Lymphocytic Leukemia. May 30, 4:00 – 7:00 p.m. ET [3:00 – 6:00 p.m. CDT]) with simultaneous publication in The Lancet*.

"The Phase 3 frontMIND results mark a potential inflection point in the treatment of patients with previously untreated, high-risk DLBCL and HGBL, where outcomes have remained largely unchanged for decades," said Steven Stein, M.D., Executive Vice President, Chief Medical Officer and Head of Late-stage Development, Incyte. "These findings support Tafa-Len-R-CHOP as a potential new standard of care option in the first-line treatment of DLBCL, with benefit observed across both cell-of-origin (COO) molecular subtypes, and we look forward to advancing our global regulatory filings as we seek to bring this option to patients."

The results build on previously reported topline data indicating the trial met its primary endpoint of progression-free survival (PFS) by investigator assessment.

The data demonstrate that Tafa-Len-R-CHOP resulted in a statistically significant and clinically meaningful improvement in PFS, with a 25% reduction in risk of disease progression or death among patients treated with Tafa-Len-R-CHOP compared with R-CHOP alone (HR 0.75 [P=0.0194]; 95% CI, 0.59–0.96; median follow-up of 35.2 months).

A PFS increase of 8.2% was seen at 2 years (71.1% with Tafa-Len-R-CHOP vs 62.9% with R-CHOP).
A PFS increase of 6.6% was seen at 3 years (67.3% with Tafa-Len-R-CHOP vs 60.7% with R-CHOP).
Additionally, point estimates suggested trends toward PFS advantage with Tafa-Len-R-CHOP are broadly consistent across prespecified subgroups, including patients with centrally confirmed lymphoma subtypes and across COO molecular subtypes (ABC [Activated B-cell-like] and GCB [Germinal Center B-cell-like]).
Treatment with Tafa-Len-R-CHOP also significantly improved the key secondary endpoint of event-free survival (EFS) compared to R-CHOP alone (HR 0.79 [P=0.0260] 95% CI, 0.64-0.97; median follow-up of 35.4 months). Additionally, interim overall survival (OS) analysis demonstrated a positive trend toward improvement (HR=0.85 [P=0.2703] 95% CI, 0.63–1.14, median follow-up of 35.9 months), with final analysis planned after additional follow-up.

"For years, R-CHOP has remained the standard first-line therapy for DLBCL, yet nearly 40% of patients experience disease progression or relapse after initial treatment, underscoring the need for innovation," said Dr. Georg Lenz, University Hospital Münster and principal investigator of the frontMIND study. "The frontMIND study shows that adding tafasitamab and lenalidomide to R-CHOP improved outcomes, including in patients with high-risk disease, who have historically faced poor prognoses and limited treatment options. These results suggest that this regimen could help broaden the first-line treatment options for this patient population."

Tafa-Len-R-CHOP was generally well tolerated, and safety was consistent with the expected safety profile of adding Tafa-Len to R-CHOP.

The most common treatment-emergent adverse events (TEAEs) in the Tafa-Len-R-CHOP group were neutropenia (70.7%), anemia (46.3%) and peripheral neuropathy (40.6%). Any grade TEAEs were similar in both treatment arms (98.6% vs 97.1%). More Grade ≥3 TEAEs occurred with Tafa-Len-R-CHOP (86.7%) vs R-CHOP alone (76.1%). The most common Grade 3 TEAEs in the Tafa-Len-R-CHOP group were anemia (22.8%), thrombocytopenia (13.1%) and neutropenia (12.4%). The most common Grade 3 TEAEs with R-CHOP alone were anemia (15.9%), febrile neutropenia (8.7%) and thrombocytopenia (6.7%).

Importantly, the incremental safety events observed with Tafa-Len-R-CHOP were well managed and did not interfere with the delivery of the R-CHOP backbone. Rates of TEAEs leading to discontinuation of all study treatment were similar between the two groups (5.2% for Tafa-Len-R-CHOP and 5.4% for R-CHOP alone). Although a higher rate of fatal TEAEs was observed with Tafa-Len-R-CHOP (5.9% vs 3.8% with R-CHOP), there were fewer overall deaths with Tafa-Len-R-CHOP (82 [18.5%]) compared to R-CHOP (97 [21.7%]), consistent with the positive trend observed in OS.

The frontMIND data support the submission of global regulatory applications for tafasitamab and lenalidomide in addition to R-CHOP for previously untreated DLBCL.

About Diffuse Large B-cell Lymphoma (DLBCL)
Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin lymphoma (NHL) in adults worldwide, representing 40% of all cases.1 It is characterized as an aggressive, fast-growing type of lymphoma that can emerge in lymph nodes or extranodal sites such as the gastrointestinal tract, skin and brain.2 Each year, approximately 24,000 people in the U.S. and up to 36,000 people in Europe are diagnosed with DLBCL.3,4 With about 40% of these patients not responding to initial therapy or relapsing thereafter,5,6 there is a high medical need for new, effective therapies, particularly for high-risk patients.

About frontMIND
The frontMIND trial (NCT04824092) is a randomized, double-blind, placebo-controlled, global Phase 3 study in patients with previously untreated high-risk diffuse large B-cell lymphoma (DLBCL) and high-grade B-cell lymphoma (HGBL).

The study enrolled 899 adults (≥18 to ≤80 years) and is evaluating the efficacy and safety of tafasitamab and lenalidomide added to R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone) compared with R-CHOP alone.

The primary endpoint of the study is investigator-assessed progression-free survival (PFS) using the Lugano 2014 criteria. Key secondary endpoints include event-free survival (EFS) by investigator assessment and overall survival (OS).

NUBEQA is indicated in the U.S. for the treatment of adult patients with metastatic castration-sensitive prostate cancer (mCSPC) both with and without docetaxel, and for the treatment of adult patients with non-metastatic castration-resistant prostate cancer (nmCRPC).1

The trial met its primary endpoint, with median cognitive change from baseline to 24 weeks in maximally changed cognitive domain (MCCD) measuring -15.8% (-38.8, -2.6) for NUBEQA compared to -36.1% (-59.3, -16.7) for enzalutamide (p=0.009) in patients with advanced prostate cancer.2 Individual cognitive domain scores increased with NUBEQA, while scores remained stable or showed mild decline with enzalutamide.2 Cognitive function was measured objectively across domains including executive function, working memory, visual memory and attention. The largest percentage change between NUBEQA and enzalutamide was observed in executive function and working memory. Executive function and working memory are primarily responsible for short term memory and management of tasks in the brain, such as following conversations, remembering directions or keeping track of information. Results were presented today as an oral abstract at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting (Abstract #5005; May 30, 2026. 4:24 – 4:36 PM CDT) in Chicago.

"When choosing treatment for advanced prostate cancer, physicians and patients increasingly consider not only survival and disease control, but also how treatment may affect the patient’s daily life, including cognitive function," said Alicia K. Morgans, MD, MPH, Medical Oncologist and Director of the Adult Survivorship Program at Dana-Farber Cancer Institute and Principal Investigator of the ARACOG trial. "Data such as these offer evidence that can help inform treatment discussions and support a more patient-focused approach to care."

"At Bayer, we are committed to supporting people living with prostate cancer by advancing innovative treatment options," said Dr. Frank Verholen, Global Medical & Evidence Lead for NUBEQA at Bayer. "Data have demonstrated that darolutamide does not have the same impact on the central nervous system as enzalutamide."

Secondary endpoints of ARACOG included comparison in rates of crossover, which was permitted at 12 or 24 weeks for significant pre-specified decline in cognitive testing or patient-reported outcome measures, or for central nervous system-associated adverse events, including falls.2 By 24 weeks, 32 patients in the NUBEQA arm and 33 patients in the enzalutamide arm were eligible for crossover.2 Of the 23 patients who crossed over, all had been randomized to enzalutamide and crossed over to NUBEQA, most commonly due to decline in objective (n=14) or subjective (n=11) cognitive testing.2 Patients qualified for cross-over based on worsening seen on objective or subjective cognitive tests. Longer-term follow-up of cognitive change and patient-reported outcome measure (PROM) analyses are ongoing.

Prostate cancer is the leading cancer diagnosis among men in the U.S.3 Around 313,780 men are diagnosed with prostate cancer each year in the U.S.3 By 2040, prostate cancer diagnoses are projected to increase to 2.9 million worldwide.4 For men with mCSPC, just over a third (~38%) will survive five years or more after diagnosis, and most progress to castration-resistant prostate cancer (CRPC), a condition with limited long-term survival. 5,6,7

About the ARACOG trial8

ARACOG (NCT04335682) is a U.S. prospective, randomized, open-label Phase II trial conducted by the Alliance for Clinical Trials in Oncology, evaluating objective and patient-reported cognitive and quality-of-life outcomes in patients with metastatic castration sensitive prostate cancer (mCSPC), metastatic castration-resistant prostate cancer (mCRPC) or non-metastatic castration-resistant prostate cancer (nmCRPC) treated with NUBEQA or enzalutamide.

Patients (N=111) were enrolled and randomized 1:1 to treatment with enzalutamide or NUBEQA. CANTAB, a validated computer-based platform evaluating five cognitive domains, was performed at baseline, 12, 24 and 48 weeks. The primary endpoint was the percent change in the maximally changed cognitive domain from baseline to 24 weeks and was compared between groups with the Wilcoxon rank sum statistic. Secondary endpoints included comparison of crossover rates. A study limitation was that crossover criteria included subjective outcomes in the context of an open-label trial. CANTAB is a research tool and not used for clinical diagnosis.

IMPORTANT SAFETY INFORMATION

Warnings & Precautions
Ischemic Heart Disease – Ischemic heart disease, including fatal cases, occurred in patients receiving NUBEQA.

In a pooled analysis of ARAMIS and ARANOTE, ischemic heart disease occurred in 3.4% of patients receiving NUBEQA and 2.2% receiving placebo, including Grade 3-4 events in 1.4% and 0.3%, respectively. Ischemic events led to death in 0.4% of patients receiving NUBEQA and 0.4% receiving placebo.

In ARASENS, ischemic heart disease occurred in 3.2% of patients receiving NUBEQA with docetaxel and 2% receiving placebo with docetaxel, including Grade 3-4 events in 1.3% and 1.1%, respectively. Ischemic events led to death in 0.3% of patients receiving NUBEQA with docetaxel and 0% receiving placebo with docetaxel.

Monitor for signs and symptoms of ischemic heart disease. Optimize management of cardiovascular risk factors, such as hypertension, diabetes, or dyslipidemia. Discontinue NUBEQA for Grade 3-4 ischemic heart disease.

Seizure – Seizure occurred in patients receiving NUBEQA.

In a pooled analysis of ARAMIS and ARANOTE, Grade 1-3 seizure occurred in 0.2% of patients receiving NUBEQA. Seizure occurred from 261 to 665 days after initiation of NUBEQA.

In ARASENS, seizure occurred in 0.8% of patients receiving NUBEQA with docetaxel, including two Grade 3 events. Seizure occurred from 38 to 1754 days after initiation of NUBEQA.

It is unknown whether anti-epileptic medications will prevent seizures with NUBEQA. Advise patients of the risk of developing a seizure while receiving NUBEQA and of engaging in any activity where sudden loss of consciousness could cause harm to themselves or others. Consider discontinuation of NUBEQA in patients who develop a seizure during treatment.

Embryo-Fetal Toxicity – The safety and efficacy of NUBEQA have not been established in females. NUBEQA can cause fetal harm and loss of pregnancy. Advise males with female partners of reproductive potential to use effective contraception during treatment with NUBEQA and for 1 week after the last dose.

Drug Interactions

Effect of Other Drugs on NUBEQA – Concomitant use of NUBEQA with a combined P-gp and strong or moderate CYP3A4 inducer decreases darolutamide exposure which may decrease NUBEQA activity. Avoid concomitant use of NUBEQA with combined P-gp and strong or moderate CYP3A4 inducers.

Concomitant use of NUBEQA with a combined P-gp and strong CYP3A4 inhibitor increases darolutamide exposure which may increase the risk of NUBEQA adverse reactions. Monitor patients more frequently for NUBEQA adverse reactions and modify NUBEQA dosage as needed.

Effects of NUBEQA on Other Drugs – NUBEQA is an inhibitor of BCRP transporter. Concomitant use of NUBEQA increases the AUC and Cmax of BCRP substrates, which may increase the risk of BCRP substrate-related toxicities. Avoid concomitant use with drugs that are BCRP substrates where possible. If used together, monitor patients more frequently for adverse reactions, and consider dose reduction of the BCRP substrate drug.

NUBEQA is an inhibitor of OATP1B1 and OATP1B3 transporters. Concomitant use of NUBEQA may increase the plasma concentrations of OATP1B1 or OATP1B3 substrates. Monitor patients more frequently for adverse reactions of these drugs and consider dose reduction while patients are taking NUBEQA.

Review the Prescribing Information of drugs that are BCRP, OATP1B1, and OATP1B3 substrates when used concomitantly with NUBEQA.

For important risk and use information about NUBEQA, please see the accompanying full Prescribing Information.

Fourteen additional patients have been dosed since first clinical data were reported at the American Society of Hematology (ASH) (Free ASH Whitepaper) 2025 Annual Meeting, bringing the total number of patients dosed to 18. The interim data presented at ASCO (Free ASCO Whitepaper) demonstrate a 100% overall response rate (ORR) and minimal residual disease (MRD)-negative bone marrow at one month post treatment in all evaluable patients.

Additional highlights of the updated data presented today:

First patient treated remains in deep, ongoing MRD-negative response beyond 10 months
Six patients with ≥ 4 months of follow up include 4 stringent complete response (sCR) and 2 very good partial response (VGPR), all with ongoing MRD-negative bone marrows
Robust generation and sustained persistence of CAR-T cells in the peripheral blood and bone marrow exceeding what is typically seen with ex vivo CAR-T therapies
Continued favorable safety and tolerability profiles; safety review committee has approved outpatient infusion
16 of 18 patients experienced cytokine release syndrome (CRS); all were Grade 1-2
One Grade 1 and one Grade 3 immune effector-cell associated neurotoxicity syndrome (ICANS) event; Grade 3 event was limited to 3 days
No delayed neurotoxicity observed
Cytopenias and Grade 3-4 infections were notably limited
No infusion-related reactions (IRRs) following dexamethasone premedication implementation
"The clinical data presented today at ASCO (Free ASCO Whitepaper) strengthens our conviction that the iGPS platform has the potential to transform the treatment experience and outcomes for patients with serious hematologic malignancies," said Kevin Friedman, Ph.D., Chief Executive Officer and Founder of Kelonia. "This expanded patient cohort continues to provide clear clinical validation of KLN-1010 and our platform. Durable and deep responses were achieved without the need for preparative chemotherapy or complex CAR-T cell manufacturing that impact patient access and treatment timelines. Combined with a safety profile consistent with traditional CAR-T therapies in multiple myeloma, we are seeing growing evidence for the potential of KLN-1010 to democratize CAR-T treatment of multiple myeloma."

"Early data from Kelonia’s lead in vivo CAR-T program continues to demonstrate highly encouraging responses in additional patients, with the benefit of extended follow-up revealing a consistent pattern of strong clinical responses over time, and a continued favorable safety profile," said ASCO (Free ASCO Whitepaper) Presenter and inMMyCAR investigator, Professor Joy Ho, MBBS, D.Phil, Royal Prince Alfred Hospital, Sydney, Australia. "The persistent generation of CAR-T cells observed across the expanded cohort reinforces the potential of KLN-1010 to make a meaningful difference for multiple myeloma patients."

Eli Lilly and Company’s proposed acquisition of Kelonia Therapeutics announced in April 2026 is pending transaction close.

About KLN-1010

KLN-1010, which has received Fast Track designation from the U.S. Food and Drug Administration (FDA), is an investigational in vivo gene therapy that generates anti-BCMA CAR-T cells, targeting the BCMA protein expressed on the surface of multiple myeloma cells. Unlike traditional CAR-T treatments, KLN-1010 is administered to patients via direct infusion and is designed to generate durable CAR-T cells inside the body after a single dose, potentially eliminating the need for long wait times to receive treatment. This may overcome several limitations faced by current CAR-T approaches, including limited access to treatment and the requirement of preconditioning chemotherapy.

About inMMyCAR

inMMyCAR is a Phase 1, open-label, dose-escalation clinical trial designed to assess the safety, tolerability, pharmacology and preliminary efficacy of a single dose of KLN-1010 in up to 40 patients. The primary endpoints are incidence and severity of treatment-emergent adverse events (TEAEs), including dose limiting toxicities (DLTs), and to establish the recommended Phase 2 dose of KLN-1010. Additional information and study site information may be found on clinicaltrials.gov (NCT07075185).

About Relapsed and Refractory Multiple Myeloma

Multiple myeloma is a hematologic malignancy characterized by the proliferation of plasma cells in the bone marrow, leading to bone destruction, anemia, renal dysfunction, and immunosuppression. It is driven by complex genetic and epigenetic alterations that promote malignant cell survival and resistance to apoptosis. Relapsed and refractory multiple myeloma is characterized by clonal evolution, drug resistance, and increased disease heterogeneity, heightening the need for accessible, personalized therapeutic strategies.
