Turning Point Therapeutics and Zai Lab Announce Exclusive License Agreement for Repotrectinib in Greater China
SHANGHAI,July 8,2020 -- Turning Point Therapeutics,Inc.(NASDAQ: TPTX),a precision oncology company developing next-generation therapies that target genetic drivers of cancer,andZai Lab(NASDAQ: ZLAB),an innovative commercial-stage biopharmaceutical company,today announced an exclusive license agreement for the development and commercialization of Turning Point's lead drug candidate,repotrectinib,inGreater China,which includes mainlandChina,Hong Kong,MacauandTaiwan.
Under the terms of the agreement,Zai Labwill obtain exclusive rights to develop and commercialize repotrectinib inGreater ChinaandTurning Point Therapeuticswill receive a$25 millionupfront payment,with potential to receive up to an additional$151 millionin development,regulatory and sales-based milestone payments. Turning Point will also be eligible to receive mid-to-high teen royalties based on annual net sales of repotrectinib inGreater China.
"With more than 700,000 newly diagnosed lung cancer patients every year inGreater China,and the development and commercialization capabilitiesZai Labhave shown over time in the region,we viewZai Labas the ideal partner to help expand the potential reach of repotrectinib," saidAthena Countouriotis,M.D.,President and Chief Executive Officer ofTurning Point Therapeutics. "Our collaboration withZai Labis a strategic step to potentially accelerate the development of repotrectinib in Greater China."
Zai Labanticipates opening additional sites for the TRIDENT-1 Phase 2 registrational clinical study of repotrectinib. The ongoing study is currently active in 11 countries globally and enrolling patients withROS1-positive advanced non-small cell lung cancer (NSCLC) andNTRK-positive solid tumors.
"We are very pleased to enter into this agreement withTurning Point Therapeutics. Repotrectinib is highly synergistic with Zai's existing pipeline and further strengthens our disease area strongholds across most common tumor types inChina,particularly in lung cancer. We are looking forward to bringing this potential best-in-class agent in the front-line setting and for patients previously treated with an approved tyrosine kinase inhibitor (TKI) where there are no approved targeted therapies," saidSamantha Du,Ph.D.,Founder,Chairwoman and Chief Executive Officer ofZai Lab.
"In China,there is only one approved targeted therapy for patients with advancedROS1-positive lung cancer and despite its efficacy,most patients eventually acquire resistance," said Dr.Lu Shun,Director ofChinese Lung Cancer Association. "The unmet need in theROS1-positive lung cancer patient population is significant. The preliminary clinical activity and safety data generated to date for repotrectinib represent a promising clinical profile. If approved,repotrectinib has the potential to be the standard of care forROS1-positive patients with advanced non-small cell lung cancer in China."
About Repotrectinib
Repotrectinib is an investigational next-generation TKI designed to effectively target ROS1 and TRK A/B/C with potential to treat TKI-naïve or -pretreated patients.ROS1rearrangement is estimated to be an oncogenic driver in approximately 2 to 3 percent of patients with advanced NSCLC inChina,and NTRK is estimated to be an oncogenic driver in approximately 0.5 percent of patients with other advanced solid tumors inChina.
Utilizing a22 July 2019data cut-off,data from the Phase 1 portion of TRIDENT-1 demonstrated the potential for repotrectinib to be best-in-class for the treatment ofROS1-positive advanced NSCLC in patients who were not previously treated with a TKI,with a 91 percent overall response rate by blinded independent central review,a median duration of response of 23.1 months,a median progression-free survival of 24.6 months,and a generally well-tolerated adverse-event profile.

AboutTurning Point Therapeutics Inc.
Turning Point Therapeuticsis 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,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 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 being studied in a Phase 1 trial of patients with advanced or metastatic solid tumors harboring genetic alterations inMET; TPX-0046,targeting RET and SRC,which is being studied in a Phase 1/2 trial of patients with advanced or metastatic solid tumors harboring genetic alterations inRET; and TPX-0131,a next-generation ALK inhibitor 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. For more information,visitwww.tptherapeutics.com.
