Zai Lab Partners with Amgen to Evaluate Lung Cancer Therapy
- Global Clinical Trial Collaboration: On April 1, Zai Lab entered into a global clinical trial collaboration with Amgen to evaluate a combination therapy for extensive-stage small cell lung cancer, showcasing strategic synergy in oncology treatment between the two companies.
- Dual-Targeting Strategy: The study will combine Zai Lab's zocilurtatug pelitecan with Amgen's IMDELLTRA, aiming to enhance clinical responses and address potential resistance pathways through complementary mechanisms, thereby improving survival chances for patients.
- Clinical Trial Progress: Zocilurtatug pelitecan has demonstrated a high response rate and a tolerable safety profile in heavily pretreated SCLC patients, indicating its therapeutic potential, especially with FDA orphan drug and fast track designations.
- New Treatment Paradigm: By combining the first-ever approved DLL3-targeting bispecific therapy, Zai Lab and Amgen aim to establish a new treatment paradigm for one of the most aggressive and lethal forms of solid tumors.
