YL212 expands Zai Lab’s lung cancer franchise and enriches its global oncology pipeline with a potential first-in-class ADC
SHANGHAI, China and CAMBRIDGE, Mass., April 27, 2023 (GLOBE NEWSWIRE) -- Zai Lab Limited (NASDAQ: ZLAB; HKEX: 9688) today announced a strategic partnership and exclusive worldwide license agreement with MediLink Therapeutics (MediLink). MediLink is an innovative drug development company focusing on next generation anti-body-drug conjugates (ADCs) and related technologies. Through this collaboration, we have expanded our lung cancer franchise and global oncology pipeline with YL212, a novel DLL3 ADC program.
YL212 is an innovative DLL3 ADC discovered by using MediLink’s proprietary TAMLIN® platform. TAMLIN® is a next generation ADC platform designed to leverage the tumor microenvironment to overcome the challenges in current ADC drugs. DLL3 is an inhibitor of the Notch ligand that is overexpressed in small cell lung cancer (SCLC) and neuroendocrine tumors. YL212 has demonstrated an encouraging preclinical profile, and our teams will work diligently together to advance it into clinical studies.
Under the terms of the agreement, MediLink will be eligible to receive certain upfront fees and development and sales-based milestone payments as well as tiered royalties on global annual net sales and potential third-party sublicensing payments. Zai Lab will be responsible for all the development and commercialization activities globally.
“We are excited to collaborate with MediLink on this program. We will leverage our capabilities to advance the global development of YL212,” said Rafael G. Amado, M.D., President, Head of Global Oncology Research and Development at Zai Lab. “This collaboration demonstrates our continued focus on developing cancer therapies including ADC drugs, further enriching our global oncology pipeline. It also complements our existing strong lung cancer portfolio. YL212 is advancing rapidly to the clinical stage, and we look forward to testing this compound in patients with limited therapeutic options.”
“With a strong track record of developing and commercializing other first- and best-in-class therapeutics in oncology, Zai Lab is an ideal partner for MediLink on this project,” said Liang Xiao, PhD, COO at MediLink. “This partnership is a great validation of our technology and capabilities. We are glad to collaborate with Zai Lab and look forward to bringing this innovative therapy to patients worldwide.”
About Zai Lab in ADC
Zai Lab is building a portfolio of potential first- and/or best-in-class ADCs. In addition to YL212, the company obtained exclusive rights in Greater China to TIVDAK (tisotumab vedotin) last year. TIVDAK is the first and only tissue factor ADC approved for recurrent or metastatic cervical cancer patients with disease progression on or after chemotherapy. At the 2023 American Association of Cancer Research (AACR) Annual Meeting, encouraging efficacy results from the innovaTV 207 Phase 2 study of TIVDAK were reported in patients with recurrent or metastatic head and neck squamous cell cancer.
About Zai Lab’s Lung Cancer Franchise
There are more than 2.2 million new cases of lung cancer globally in 2020.1 Lung cancer is the leading cause of cancer death, accounting for about one-fifth of all cancer deaths.1 Zai Lab has established a broad and differentiated portfolio for the treatment of lung cancer.
As of today, our targeted therapies in development cover approximately 70% of all newly diagnosed NSCLC patients in China. The assets in late-stage development include:
- KRAZATI® (adagrasib, KRASG12C): a highly selective and potent oral small-molecule inhibitor of KRASG12C, that has been granted accelerated approval by the U.S. Food and Drug Administration (FDA) for adult patients with KRASG12C-mutated locally advanced or metastatic NSCLC who have received at least one prior systemic therapy. Adagrasib has shown clinically to be a Central Nervous System (CNS) penetrant and continues to be evaluated as monotherapy and in combination with other anti-cancer therapies in patients with advanced KRASG12C-mutated solid tumors.
- Repotrectinib (ROS1/NTRK): a potential best-in-class, next-generation ROS1/NTRK inhibitor with differentiated duration of response for patients with ROS1-positive first-line NSCLC. Repotrectinib has been granted three Breakthrough Therapy Designations (BTDs) from the FDA and three BTDs from China’s National Medical Products Administration. Repotrectinib is being studied in the registrational Phase I/II TRIDENT-1 study.
Other targeted therapies in clinical development for the treatment of lung cancer include zipalertinib (EGFR exon 20 insertion), ZL-2313 (BLU-945, EGFR) and elzovantinib (MET).
In addition, Tumor Treating Fields (TTFields) is an innovative therapy that can be added to cancer treatment modalities in approved indications and demonstrates enhanced effects across solid tumor types, including NSCLC. LUNAR, which is a pivotal study for patients with stage 4 NSCLC who progressed during or after platinum-based therapy, met its primary endpoint, demonstrating a statistically significant and clinically meaningful improvement in overall survival.
About Small Cell Lung Cancer (SCLC) and Neuroendocrine Tumors
SCLC and neuroendocrine tumors are diseases with significant unmet medical needs globally. There are over 300,000 SCLC annual incidences globally.1 More than 88% of SCLC patients overexpress DLL3 and could benefit from targeted therapeutic agents.2 In addition, DLL3 is a promising target highly expressed in several tumors with neuroendocrine features. There are approximately 171,000 people living with neuroendocrine tumors in the United States, and the numbers are continuing to increase, but the treatment options remain limited.3
