Olverembatinib Granted Breakthrough Therapy Designation for the Treatment of Philadelphia Chromosome-Positive (Ph+) Acute Lymphoblastic Leukemia (ALL)
ROCKVILLE, Md. and SUZHOU, China, March 05, 2025 (GLOBE NEWSWIRE) -- Ascentage Pharma (NASDAQ: AAPG; HKEX: 6855), a global biopharmaceutical company engaged in discovering, developing, and commercializing therapies to address global unmet medical needs primarily for hematological malignancies, today announced that its drug, olverembatinib, has been granted a Breakthrough Therapy Designation (BTD) by the Center for Drug Evaluation (CDE) of China’s National Medical Products Administration (NMPA), for combination with low-intensity chemotherapy for the first-line treatment of newly-diagnosed patients with Philadelphia chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL).
This marks the third BTD granted to olverembatinib in China, with the first BTD granted in March 2021, for the treatment of patients with chronic-phase chronic myeloid leukemia (CML-CP) resistant and/or intolerant to first- and second-generation tyrosine kinase inhibitors (TKIs); and the second BTD granted in June 2023, for the treatment of patients with succinate dehydrogenase (SDH)-deficient gastrointestinal stromal tumor (GIST) who had received first-line treatment.
BTDs are commonly granted to innovative drugs or modified novel drugs that are intended for the prevention or treatment of serious life-threatening diseases and/or conditions that severely impact the quality of life for which there is no existing treatment or where sufficient evidence indicates advantages over currently available treatment options. Drugs that have been granted BTDs are prioritized by the CDE in communications, and in receiving guidance to advance the drug development progress. Furthermore, if the applicant meets the relevant conditions after evaluation, BTD-designated drugs will be eligible for Priority Review status and conditional approvals upon submission of China’s version of a New Drug Application (NDA). In conclusion, granting of BTDs effectively accelerates development and review of innovative drugs and modified novel drugs presenting significant clinical value or addressing urgent unmet clinical needs.
The incidence rate of ALL in China is approximately 0.69/100,000; and Ph+ ALL, accounting for 20%-30% of all ALL cases in adults, is more common in the elderly with poor tolerance to treatment1. Prior to the introduction of TKIs, a class of targeted small molecule compounds, the five-year overall survival (OS) rate of patients with Ph+ ALL treated with chemotherapy alone was below 20%2. The clinical adoption of TKIs has resulted in a new clinical paradigm for patients with Ph+ ALL. The first- and second-generation TKIs still present considerable limitations, including a high relapse rate, short disease-free survival and poor prognosis. Moreover, no TKI has yet been approved for the first-line treatment of Ph+ ALL in China, resulting in a huge unmet medical need in the field.
Ascentage Pharma’s approved drug, olverembatinib, is the first China-approved third-generation BCR-ABL inhibitor and it is being jointly commercialized in China by Ascentage Pharma and Innovent Biologics. To date, olverembatinib has been approved in China for the treatment of adult patients with TKI-resistant CML-CP or accelerated-phase CML (CML-AP) harboring the T315I mutation and adult patients with CML-CP resistant to and/or intolerant of first- and second-generation TKIs. All approved indications have been included into the China National Reimbursement Drug List (NRDL).
In July 2023, the CDE cleared a global registrational Phase III study of olverembatinib in combination with chemotherapy versus imatinib in combination with chemotherapy for the treatment of patients with naïve Ph+ ALL, paving the way for olverembatinib to potentially become the first TKI approved in China for the treatment of Ph+ ALL in the first-line setting.
Dr. Yifan Zhai, Chief Medical Officer of Ascentage Pharma, said, “We are much encouraged to have olverembatinib’s clinical value once again recognized by the regulatory authority in China. This BTD underscores the therapeutic potential and utility of olverembatinib in Ph+ ALL, a hematologic malignancy with dismal prognosis. Moving forward, we will strive to accelerate this clinical development program for olverembatinib and bring it to more patients as quickly as possible.”
