ROCKVILLE,
Md. and SUZHOU, China, January 14, 2026—Ascentage Pharma Group International (NASDAQ: AAPG; HKEX: 6855), a global, commercial
stage, integrated biopharmaceutical company engaged in the discovery, development and commercialization of novel, differentiated therapies
to address unmet medical needs in cancer, announced that its Chairman and CEO, Dajun Yang, M.D., Ph.D., presented at the 44th Annual
J.P. Morgan Healthcare Conference. In the corporate presentation, Dr. Yang provided an overview of milestone achievements in 2025 and
outlined the Company’s global innovation strategy for 2026.
Dr.
Yang said, “The annual J.P. Morgan Healthcare Conference provides an important platform for us to engage with peers from around
the world and showcase our strategy and progress. For Ascentage Pharma, 2025 has been a critical year in which we accelerated our global
expansion, advancing product commercialization, global clinical development, and pipeline innovation. To date, we have built a powerful
engine for innovation in hematologic malignancies and solid tumors, harnessing a diverse range of mechanisms and synergies between core
components that include our commercialized products, late-stage programs in solid tumors, as well as our early-stage innovative therapies
that utilize our cutting-edge protein degradation technology. This multi-faceted global portfolio of products and clinical programs has
well positioned Ascentage Pharma for future challenges and laid a solid foundation for sustained growth. Entering 2026, Ascentage Pharma
is opening a new chapter on its global innovation strategy. We remain steadfastly committed to our mission of addressing unmet clinical
needs around the world, and accelerate the development of our promising innovative therapeutics for the benefit of patients worldwide.”
Dual-Engine
Driven by Two Core Products: Building a Global Hematologic Malignancy Treatment Landscape
The
Company’s two core products, the third-generation BCR-ABL inhibitor Olverembatinib and the Bcl-2 inhibitor Lisaftoclax, both achieved
significant progress in 2025 and represent main growth drivers for 2026. Together, they generate powerful “dual-engine” effects
that will drive the Company’s future growth and support the development of a global portfolio of innovative therapies covering
a broad range of hematologic malignancies.
Dr.
Yang continued, “In the past year, Ascentage Pharma has made progress across multiple clinical studies on its key drug candidates
globally, and presented data from these studies at prestigious international academic congresses. These data underscored the Company’s
potential in delivering clinical breakthroughs for challenging hematologic malignancies and the global competitiveness of its products.”
Developing
the Next-Generation BTK Degrader: Propelling Strategic Expansion of Global Innovative Pipeline
Achieving
breakthroughs in translational medicine and the development of a diverse pipeline, Ascentage Pharma has received an investigational new
drug (IND) clearance from the U.S. FDA for APG-3288, the first novel, highly potent and selective BTK degrader developed utilizing Ascentage
Pharma’s proprietary proteolysis-targeting chimera (PROTAC) technology platform. This clearance initiates Ascentage Pharma’s
clinical development in the field of targeted degradation and lays a strong foundation for future exploration of the combinatory potential
between APG-3288 and the Company’s existing proprietary small-molecule agents.
Adding
to the dual-engine effect generated by Olverembatinib and Lisaftoclax, other assets in the Company’s pipeline are also making rapid
progress, forming a portfolio of advancing programs. The Company’s other key clinical programs include:
APG-5918
(EED inhibitor): Preclinical data have shown therapeutic potential in hematologic malignancies (multiple myeloma and T-cell lymphoma)
and solid tumors (prostate cancer). For non-hematologic indications, the Company is conducting a Phase I study in patients with anemia
in China.
APG-2449
(FAK/ALK/ROS1 inhibitor): Has entered global registrational Phase III studies in non-small cell lung cancer (NSCLC), representing a major
breakthrough in the Company’s expansion into solid tumors.
Alrizomadlin
(APG-115; MDM2-p53 inhibitor): Currently being evaluated in a Phase II study and has shown clinical potential in solid tumors such as
adenoid cystic carcinoma (ACC).
Pelcitoclax
(APG-1252; Bcl-2/Bcl-xL inhibitor): Currently being evaluated in a Phase II study, having shown clinical potential in a range of tumor
types including EGFR-mutant NSCLC, relapsed/refractory non-Hodgkin lymphoma, ovarian cancer, and endometrial carcinoma.
Outlook
for 2026
In
the presentation, Dr. Yang touched on a number of potential milestones and catalysts expected in 2026.
In
global clinical development: Advance multiple registrational Phase III studies including GLORA, GLORA-4, POLARIS-1, and POLARIS-2.
In
commercialization: Continued growth in commercial sales, broader patient accessibility and coverage across 1,500 hospitals; Inclusion
in NRDL coverage of Lisaftoclax in China.
On
early-stage clinical programs: BTK Protein Degrader APG-3288 global Phase I PK, safety, tolerability, efficacy data, including U.S. and
China; Advancement of EED Inhibitor APG-5918 in oncology and anemia in the U.S. and China.
*Olverembatinib,
Lisaftoclax, Alrizomadlin, Pelcitoclax, APG-3288, APG-5918, and APG-2449 are currently under investigation and have not yet been approved
by the U.S. FDA.
About
Ascentage Pharma
Ascentage
Pharma Group International (NASDAQ: AAPG; HKEX: 6855) (“Ascentage Pharma” or the “Company”) is a global, commercial
stage, integrated biopharmaceutical company engaged in the discovery, development and commercialization of novel, differentiated therapies
to address unmet medical needs in cancer. The Company has built a rich pipeline of innovative drug products and candidates that includes
inhibitors targeting key proteins in the apoptotic pathway, such as Bcl-2 and MDM2-p53, as well as next-generation kinase inhibitors.
The
lead asset, Olverembatinib, is the first novel third-generation BCR-ABL1 inhibitor approved in China for the treatment of patients with
CML in chronic phase (CML-CP) with T315I mutations, CML in accelerated phase (CML-AP) with T315I mutations, and CML-CP that is resistant
or intolerant to first and second-generation TKIs. All indications are covered by the China National Reimbursement Drug List (NRDL).
The Company is currently conducting an FDA-cleared, global registrational Phase III trial, or POLARIS-2, of Olverembatinib for CML, as
well as global registrational Phase III trials for patients with newly diagnosed Ph+ ALL and SDH-deficient GIST patients.
The
Company’s second approved product, Lisaftoclax, is a novel Bcl-2 inhibitor for the treatment of various hematologic malignancies.
Lisaftoclax is being commercialized in China following National Medical Products Administration (NMPA) approval for the treatment of
adult patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) who have previously received at least one systemic
therapy including BTK inhibitors. The Company is currently conducting four global registrational Phase III trials: the FDA-cleared GLORA
study of Lisaftoclax in combination with BTK inhibitors in patients with CLL/SLL previously treated with BTK inhibitors for more than
12 months with suboptimal response; the GLORA-2 study in patients with newly diagnosed CLL/SLL; the GLORA-3 study in newly diagnosed,
elderly and unfit patients with acute myeloid leukemia (AML); and the GLORA-4 study in patients with newly diagnosed higher-risk myelodysplastic
