Takeda Signs Option Agreement with Ascentage Pharma to Enter into Exclusive Global License for Olverembatinib, a Third-Generation BCR-ABL Tyrosine Kinase Inhibitor (TKI)

− Takeda to Receive Exclusive Option to License Global Rights to Olverembatinib in All Territories Outside of Mainland China, Hong Kong, Macau, Taiwan and Russia

− Olverembatinib Has the Potential to Address Significant Unmet Need for Patients with Chronic Myeloid Leukemia Following Treatment with Currently Approved TKIs

− Ascentage Pharma to Advance Late-Stage Clinical Development of Olverembatinib Prior to Potential Exercise of the Option to License

Takeda (TSE:4502/NYSE:TAK) today announced the signing of an option agreement with Ascentage Pharma to enter into an exclusive license agreement for olverembatinib, an oral, potentially best-in-class, third-generation BCR-ABL tyrosine kinase inhibitor (TKI), which is currently in development for chronic myeloid leukemia (CML) and other hematological cancers. If exercised, the option would allow Takeda to license global rights to develop and commercialize olverembatinib in all territories outside of mainland China, Hong Kong, Macau, Taiwan and Russia.

Despite the impact TKIs have had in the treatment of patients with CML, there remains significant unmet need for patients whose disease is resistant or refractory to these therapies or who develop hard-to-treat mutations following these treatments.

“Takeda has a long history of driving important treatment advances for patients, particularly those with hematological cancers facing treatment gaps,” said Teresa Bitetti, president of the Global Oncology Business Unit at Takeda. “We are highly encouraged by the promising results olverembatinib has shown in the clinic to date and excited to have the opportunity to potentially further develop and deliver it to patients with chronic myeloid leukemia and other hematological cancers. This agreement aligns with our goal to support the advancement of both internal and external innovation to best serve patients.”

As part of the agreement, Ascentage Pharma will continue to be solely responsible for all clinical development of olverembatinib prior to potential exercise of the option to license. Olverembatinib is currently approved and marketed in China for the treatment of adult patients with TKI-resistant chronic-phase CML (CP-CML) or accelerated-phase CML (AP-CML) harboring the T315I mutation and in adult patients with CP-CML resistant to and/or intolerant of first- and second-generation TKIs.

"We are thrilled to enter into this agreement with Takeda, which would allow us to leverage the global commercial expertise of an organization with a proven track record and global oncology footprint to potentially broaden the impact olverembatinib could have on patients in need around the world,” said Dr. Dajun Yang, Chairman and CEO of Ascentage Pharma. “We have seen the impact olverembatinib has had on patients with CML in China and look forward to progressing development of olverembatinib in POLARIS-2, the global registrational Phase 3 study in previously treated adult patients with CP-CML with or without the T315I mutation.”

Under the terms of this agreement, Ascentage Pharma will receive an option payment of $100 million upon signing of the exclusive option to license agreement and will be eligible for an option exercise fee and additional potential milestone and royalty payments if Takeda exercises the option to license olverembatinib, with the exercise of the option being subject to customary regulatory approvals. Additionally, Ascentage Pharma will receive a minority equity investment from Takeda.
