Seagen and Zai Lab Announce Regional Strategic Collaboration and License Agreement for TIVDAK® (tisotumab vedotin-tftv)

Zai Lab Limited
Zai Lab Limited

-- Zai Lab Obtains Exclusive Rights to Develop and Commercialize TIVDAK, an FDA-approved First-in-Class Antibody-Drug Conjugate (ADC), in Mainland China, Hong Kong, Macau, and Taiwan --

-- Zai Lab will Leverage its Leadership in Women’s Cancer in China to Commercialize and Expand Patient Access to TIVDAK --

-- Collaboration Supports Regional Patient Enrollment for InnovaTV 301, a Global Phase 3 Trial of TIVDAK in Patients with Recurrent or Metastatic Cervical Cancer --

SHANGHAI and CAMBRIDGE, Mass. and BOTHELL, Wash., Sept. 27, 2022 (GLOBE NEWSWIRE) -- Zai Lab Limited (Nasdaq: ZLAB; HKEX: 9688), a patient-focused, innovative, commercial-stage global biopharmaceutical company, and Seagen Inc. (Nasdaq: SGEN), a world leader and pioneer in antibody-drug conjugate (ADC) therapies today announced an exclusive collaboration and license agreement for the development and commercialization of TIVDAK® (tisotumab vedotin-tftv) in mainland China, Hong Kong, Macau, and Taiwan. TIVDAK is the first and only ADC approved in the U.S. for the treatment of adult patients with recurrent or metastatic cervical cancer with disease progression on or after chemotherapy.

Under the terms of the agreement, Seagen will receive an upfront payment of $30 million, as well as development, regulatory, and commercial milestone payments, and tiered royalties on net sales of TIVDAK in the Zai Lab territory. Based on the existing TIVDAK co-development and co-commercialization collaboration between Seagen and Genmab (Nasdaq: GMAB), all upfront, milestone payments, and royalties will be shared 50/50 with Genmab.

In 2021, the U.S. Food and Drug Administration (FDA) granted accelerated approval for TIVDAK for the treatment of adult patients with recurrent or metastatic cervical cancer with disease progression on or after chemotherapy. As verification and description of clinical benefit in the U.S., and to support further global regulatory applications, a confirmatory phase 3 open-label, randomized, global clinical trial, innovaTV 301, is ongoing.

“This agreement enables us to leverage Zai Lab’s strong expertise in developing and commercializing innovative medicines in the licensed territory,” said Natasha Hernday, EVP Corporate Development and Alliance Management, Seagen. “We are delighted to collaborate with Zai Lab, including on the phase 3 innovaTV 301 trial, an important component of expanding the availability of TIVDAK to recurrent or metastatic cervical cancer patients around the world. TIVDAK is also under evaluation and development in early trials for first-line cervical cancer and certain other solid tumors.”

“Zai Lab has a significant presence treating women’s cancers in China, and TIVDAK is an important addition to our oncology commercial portfolio. Treatments for cervical cancer remain a significant unmet need in China with approximately 110,000 new cases annually 1, and currently there are few effective therapeutic options available,” said William Liang, Chief Commercial Officer, President of Greater China at Zai Lab. “We look forward to this collaboration with Seagen to make TIVDAK available for patients in China as we expand our oncology portfolio.”

“Following progression on first-line standard of care therapy, there are limited treatment options, and chemotherapy has low objective response rates with poor outcomes,” said Dr. Lingying Wu, Director of the Department of Gynecologic Oncology, National Cancer Center / National Clinical Research Center for Cancer / Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College. “This represents one of the biggest challenges faced by gynecologic oncologists with significant unmet needs for new therapies. We believe TIVDAK could become an important treatment option for patients with cervical cancer in China, as it demonstrated clinically meaningful, durable responses with a tolerable safety profile.”

About Cervical Cancer in China
Cervical cancer remains one of the leading causes of cancer death in women in China and globally. An estimated 110,000 new cases of cervical cancer occur annually in China1. Treatment options are limited for patients with recurrent or metastatic cervical cancer with disease progression on or after chemotherapy. TIVDAK is currently not approved in this region and is well positioned to provide a new option for previously treated advanced cervical cancer patients who currently have limited treatment options and poor outcomes.

About TIVDAK (tisotumab vedotin-tftv)
TIVDAK (tisotumab vedotin-tftv) is an ADC composed of Genmab’s human monoclonal antibody directed to tissue factor (TF) and Seagen’s ADC technology that utilizes a protease-cleavable linker that covalently attaches the microtubule-disrupting agent monomethyl auristatin E (MMAE) to the antibody. Nonclinical data suggests that the anticancer activity of TIVDAK is due to the binding of the ADC to TF expressing cancer cells, followed by internalization of the ADC-TF complex, and release of MMAE via proteolytic cleavage. MMAE disrupts the microtubule network of actively dividing cells, leading to cell cycle arrest and apoptotic cell death. In vitro, TIVDAK also mediates antibody-dependent cellular phagocytosis and antibody-dependent cellular cytotoxicity.
