BeiGene, Ltd. and Mirati Therapeutics have entered an exclusive license agreement for the development, manufacturing and commercialization of Mirati’s sitravatinib in Asia, Australia, and New Zealand. 

Mirati will retain exclusive rights for the development, manufacturing and commercialization of sitravatinib for the rest of world.

Sitravatinib is an investigational tyrosine kinase inhibitor that has demonstrated potent inhibition of receptor tyrosine kinases (RTKs), including TAM family receptors (TYRO3, Axl, MER), split family receptors (VEGFR2, KIT) and RET. It is being evaluated by Mirati as a single agent in a Phase 1b expansion trial in patients whose tumors harbor specific genetic alterations in non-small cell lung cancer (NSCLC) and other tumors types.  Sitravatinib has shown encouraging interim results in an ongoing Phase 2 trial in combination with nivolumab in NSCLC patients who have progressed after prior treatment with a checkpoint inhibitor.

“We are delighted to enter into this exclusive clinical development and commercialization agreement for sitravantinib and look forward to working with the experienced team at Mirati. Sitravatinib is an exciting compound that has demonstrated a unique tyrosine kinase inhibition profile and promising clinical activity both as a single agent and in combination with a checkpoint inhibitor in non-small cell lung cancer. This collaboration complements our portfolio and will allow us to investigate sitravatinib in combination with tislelizumab, our investigational anti-PD-1 antibody, in China and the rest of the licensed territory,” said John V. Oyler, Founder, chief executive officer, and chairman of BeiGene.

Under the agreement Mirati will receive an upfront cash payment of $10 million from BeiGene. Additionally, Mirati is eligible to receive up to $123 million of additional payments based upon the achievement of certain development, regulatory and sales milestones as well as significant royalties on future sales of sitravatinib in the licensed territory.
