Zai Lab Secures Exclusive Right to Develop and Commercialize TPX-0022, Turning Point’s MET/SRC/CSF1R Inhibitor, in Greater China
Turning Point to Receive $25 Million Upfront, with Up to Approximately $336 Million in Potential Milestone Payments and Royalties
SAN DIEGO and SHANGHAI and SAN FRANCISCO, Jan. 11, 2021 (GLOBE NEWSWIRE) -- Turning Point Therapeutics, Inc. (NASDAQ: TPTX), a precision oncology company developing next-generation therapies that target genetic drivers of cancer, and Zai Lab (NASDAQ: ZLAB; HKEX: 9688), an innovative commercial-stage biopharmaceutical company, today announced an expansion of their collaboration.
Under the terms of the new agreement, Zai Lab will obtain exclusive rights to develop and commercialize TPX-0022, Turning Point’s MET, SRC and CSF1R inhibitor, in Greater China, which includes mainland China, Hong Kong, Macau and Taiwan. Turning Point will receive a $25 million upfront payment, with up to approximately $336 million in potential development, regulatory and sales-based milestone payments. Turning Point will also be eligible to receive mid-teen- to low-twenty-percent royalties based on annual net sales of TPX-0022 in Greater China. In addition, Turning Point will have the right of first negotiation to develop and commercialize an oncology drug candidate discovered by Zai Lab.
This agreement builds on Zai Lab and Turning Point’s existing relationship under the exclusive licensing agreement announced by the companies in July 2020, under which Zai Lab gained the exclusive right to develop and commercialize Turning Point’s lead drug candidate, repotrectinib, in Greater China.
“The higher incidence of MET-driven cancers – particularly in gastric and lung cancer – in Asian countries led us to initiate the development of TPX-0022 in Greater China following our encouraging initial data from the Phase 1 SHIELD-1 study,” said Athena Countouriotis, M.D., president and chief executive officer of Turning Point. “We have great confidence in Zai Lab as our partner to advance this important drug candidate in a key region of the world. Zai Lab also has a promising discovery pipeline and we are pleased to receive the right of first negotiation for a drug candidate from Zai’s discovery pipeline.”
Dr. Samantha Du, Founder, Chairperson and Chief Executive Officer of Zai Lab, said, “Turning Point has assembled a formidable pipeline of next-generation oncology target therapies, and we are very pleased to broaden our global collaboration and strategic partnership. We believe TPX-0022 is a promising drug candidate that is also highly synergistic with our portfolio in gastric and lung cancer.”
Jin Li, M.D., Professor, Chairman of Chinese Society of Clinical Oncology Foundation and Director of Department of Oncology, Tongji University Shanghai East Hospital said, “The initial safety and efficacy data for TPX-0022 are promising, and its novel mechanism to target MET, SRC and CSF1R encourages us to investigate its therapeutic potential further. We are particularly interested in the early but promising findings in patients with MET-driven gastric cancer and look forward to advancing the study of TPX-0022 in this area of high unmet need in China.”
Initial data from the SHIELD-1 study reported in a late-breaker oral presentation at the EORTC-NCI-AACR symposium highlighted preliminary clinical activity, including objective responses across multiple tumor types and a generally tolerable safety profile.
TPX-0022 is an orally bioavailable multi-targeted kinase inhibitor with a novel three-dimensional macrocyclic structure that inhibits the MET, CSF1R (colony stimulating factor 1 receptor) and SRC kinases. TPX-0022 has completed IND-enabling studies and cleared its IND. During the second half of 2019, Turning Point initiated the SHIELD-1 Phase 1 clinical trial of TPX-0022 for the treatment of advanced or metastatic solid tumors with abnormal MET/HGF or CSF1R/SCF1R signaling.
MET is a receptor tyrosine kinase that binds with high affinity to hepatocyte growth factor (HGF). MET alterations, including point mutations, amplifications, fusions, exon 14 skipping, and the generation of HGF-MET autocrine loops have been reported in many cancers. MET amplification has been detected in up to 20 percent of non-small cell lung cancer patients with EGFR mutations who acquired resistance to Iressa (gefitinib), Tarceva (erlotinib) or Tagrisso (osimertinib) treatment. SRC is a kinase involved in the MET signaling pathway. Inhibition of SRC has the potential to reduce or abolish the upregulation of HGF. Targeting CSF1R leads to the modulation of tumor-associated macrophages (TAMs), a type of immune cell that suppresses the T-cell mediated anti-tumor immune response, which is a promising therapeutic strategy for TPX-0022 as a single agent or in combination with standard of care chemotherapy and immunotherapy in various solid tumors.
About Turning Point Therapeutics Inc.
Turning Point Therapeutics is a clinical-stage precision oncology company with a pipeline of internally discovered investigational drugs designed to address key limitations of existing cancer therapies. The company’s lead drug candidate, repotrectinib, is a next-generation kinase inhibitor targeting the ROS1 and TRK oncogenic drivers of non-small cell lung cancer and advanced solid tumors. Repotrectinib, which is being studied in a registrational Phase 2 study called TRIDENT-1 in adults and a Phase 1/2 study in pediatric patients, has shown antitumor activity and durable responses among kinase inhibitor treatment-naïve and pre-treated patients. The company’s pipeline of drug candidates also includes TPX-0022, targeting MET, CSF1R and SRC, which is in a Phase 1 study called SHIELD-1 in patients with advanced or metastatic solid tumors harboring genetic alterations in MET; RET-inhibitor TPX-0046, which is in a Phase 1/2 study of patients with advanced or metastatic solid tumors harboring genetic alterations in RET; and ALK-inhibitor TPX-0131, which is in IND-enabling studies. Turning Point’s next-generation kinase inhibitors are designed to bind to their targets with greater precision and affinity than existing therapies, with a novel, compact structure that has demonstrated an ability to potentially overcome treatment resistance common with other kinase inhibitors. The company is driven to develop therapies that mark a turning point for patients in their cancer treatment.
