New Indication of Olverembatinib Included into China 2024 National Reimbursement Drug List

ROCKVILLE, Md. and SUZHOU, China, Nov. 28, 2024 /PRNewswire/ -- Ascentage Pharma (6855.HK), a global biopharmaceutical company engaged in discovering, developing and commercializing therapies to address global unmet medical needs primarily for malignancies, today announced that the new indication - adult patients with chronic-phase chronic myeloid leukemia (CML-CP) resistant and/or intolerant of first-and second-generation tyrosine kinase inhibitors (TKIs) - of its novel drug, olverembatinib (HQP1351), has been included into the China 2024 National Reimbursement Drug List (NRDL), effective January 1, 2025. This indication was added to the NRDL through the simple contract renewal process. The previously included indication of adult patients with CML-CP or accelerated-phase CML (CML-AP) harboring the T315I mutation will maintain its reimbursable status on the NRDL.

Olverembatinib is a novel drug developed by Ascentage Pharma with support from the National Major New Drug Development Program in China and the first third-generation BCR-ABL inhibitor approved by the China National Medical Products Administration (NMPA). As a novel drug, olverembatinib can effectively target BCR-ABL and a spectrum of BCR-ABL mutants, including the T315I mutation. In November 2021, olverembatinib received its first approval in China, thus became the first therapy approved for the treatment of T315I mutant CML in the country. In November 2023, olverembatinib was approved for the treatment of adult patients with CML-CP resistant and/or intolerant of first-and second-generation TKIs. Olverembatinib is being jointly commercialized in China by Ascentage Pharma and Innovent Biologics.

CML is a hematologic malignancy of the white blood cells. The introduction of BCR-ABL TKIs have significantly improved the management of CML. However, TKI resistance is still a global challenge for CML treatment. 20%-40% of patients fail to achieve desired treatment outcome due to resistance or intolerance to TKIs^1-3, thus leading to disease progression or even death. The successful renewal and the inclusion of additional indication of olverembatinib in the NRDL is expected to greatly improve the drug's accessibility, bringing benefit to more and a broader population of patients with CML in China.

"We are glad that the new indication of olverembatinib has been included into the NRDL through the simple contract renewal process," said Dr. Dajun Yang, Chairman and CEO of Ascentage Pharma. "This decision reaffirms the importance of olverembatinib as an innovative drug that has the potential to fulfill the urgent unmet needs and treatment gaps in CML. With its new indication included into the NRDL at the third anniversary of the initial approval in China, olverembatinib is positioned to bring renewed hope to more patients with CML, thereby helping countless families and communities. Moving forward, we will work actively to ensure the rapid rollout of the expanded insurance coverage. We are confident these efforts will make olverembatinib more accessible and affordable, ultimately allowing more patients and their families to benefit from this novel therapeutic as soon as possible."

About Olverembatinib

Developed by Ascentage Pharma, the novel drug olverembatinib is an orally-available third-generation tyrosine kinase inhibitor (TKI), and the first China-approved third-generation BCR-ABL inhibitor that can effectively target BCR-ABL and a spectrum of BCR-ABL mutants, including the T315I mutation. Olverembatinib, developed with support from the National Major New Drug Development Program in China, has also been granted Priority Review designations and Breakthrough Therapy designations by the Center for Drug Evaluation (CDE) of China National Medical Products Administration (NMPA).

At present, olverembatinib has been approved in China for the treatment of adult patients with TKI-resistant chronic-phase chronic myeloid leukemia (CML-CP) or accelerated-phase CML (CML-AP) harboring the T315I mutation; and adult patients with CML-CP resistant and/or intolerant of first-and second-generation TKIs.

In addition to CML, olverembatinib has also shown potential clinical benefits to patients with Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL). A global registrational Phase III study of olverembatinib in newly diagnosed patients with Ph+ ALL is currently underway, potentially paving the way for olverembatinib become the first China-approved TKI for the treatment of patients with Ph+ ALL in the first-line setting. In the area of solid tumors, olverembatinib is being evaluated in a global registrational Phase III study for the treatment of succinate dehydrogenase- (SDH-) deficient gastrointestinal stromal tumor (GIST) and has already been granted a Breakthrough Therapy designation by the China CDE.

As a novel drug, olverembatinib has received widespread interest from the global hematology community. The clinical results of olverembatinib have been selected for oral presentations at the American Society of Hematology (ASH) Annual Meetings for seven consecutive years. To date, olverembatinib has been granted four Orphan Drug Designations and a Fast Track Designation by the US Food and Drug Administration (FDA), and an Orphan Designation by the EMA of the EU. In February 2024, olverembatinib was cleared by the US FDA to enter a global registrational Phase III study.

In July 2021, Ascentage Pharma (6855.HK) and Innovent Biologics (1801.HK) reached the agreement regarding the joint development and commercialization of olverembatinib in China.

In June 2024, Ascentage Pharma and Takeda, a multinational pharmaceutical company, entered into an Exclusive Option Agreement for olverembatinib. If exercised, the Option would allow Takeda to license global rights to develop and commercialize olverembatinib in all territories outside of, among others, the mainland China, Hong Kong China, Macau China, and Taiwan China.
