Tesaro, Inc., an oncology-focused biopharmaceutical company, and Zai Lab (Shanghai) Co.,Ltd., a biopharmaceutical company based in China, announced a collaboration to support the development and commercialization of niraparib for patients in China and the potential to advance two immuno-oncology programmes outside of China.This partnership reflects the commitment of both companies to develop novel therapeutic approaches for people living with cancer around the world.
Within this collaboration, Tesaro has granted to Zai Lab an exclusive license for the development of niraparib specifically for the China market, which includes an option for Tesaro to participate in the commercialization of niraparib in greater China. The companies will establish a joint steering committee to review and oversee all development and commercialization plans. In addition, Tesaro has the option to license two novel, discovery-stage immuno-oncology programmes from Zai Lab.
"Tesaro is devoted to providing transformative therapies for people bravely facing cancer, and this partnership will enable us to globalize our mission," said Lonnie Moulder, CEO of Tesaro. "The Zai Lab team has a track record of regulatory and development successes in China, and we are excited to work with them to quickly advance new treatment options for patients."
Samantha Du, chairman and CEO of Zai Lab, added, "We are delighted to partner with Tesaro, a leader in global oncology drug development. Ovarian and other cancer types that niraparib is being evaluated in are areas of large unmet medical need in China, with very limited treatment options. Our collaboration with Tesaro will bring this exciting new product candidate quickly to the Chinese patients, and we look forward to working with Tesaro."
In addition to an upfront payment, Tesaro will be eligible to receive milestone payments contingent upon Zai Lab achieving certain specified development and commercial goals. Should Tesaro elect not to participate in the commercialization of niraparib in China, Tesaro will be eligible to receive tiered, double-digit royalty payments on annual net sales from Zai Lab. Additional financial details were not disclosed.
Niraparib is an oral, once-daily PARP inhibitor that is currently being evaluated in four ongoing pivotal trials. Tesaro is building a robust niraparib franchise by assessing activity across multiple tumour types and by evaluating several potential combinations of niraparib with other therapeutics. The ongoing development program for niraparib includes a phase 3 trial in patients with recurrent ovarian cancer (the NOVA trial); a Phase 3 trial in patients with first-line ovarian cancer (the PRIMA trial); a registrational phase 2 treatment trial in patients with ovarian cancer (the QUADRA trial); and a phase 3 trial for the treatment of patients with BRCA-mutant breast cancer (the BRAVO trial). Several combination studies are also underway, including trials of niraparib plus pembrolizumab and bevacizumab. Janssen Biotech has licensed rights to develop and commercialize niraparib specifically for patients with prostate cancer worldwide, except in Japan.
