Zanidatamab data demonstrate clinical potential of novel bispecific antibody in HER2-targeted biliary tract and gastric cancers
Additional presentations, including a lurbinectedin oral presentation in small cell lung cancer (SCLC), underscore the strength of Jazz's solid tumor portfolio and the company's commitment to address difficult-to-treat tumors
"The compelling data being presented at ESMO by Jazz and partners, in particular for zanidatamab in biliary tract and gastric cancers, demonstrate the clinical potential of our solid tumor oncology development programs to raise the standard of care for some of the most difficult-to-treat cancers," said Rob Iannone, M.D., M.S.C.E., executive vice president, global head of research and development of Jazz Pharmaceuticals. "Through our expanding research in solid tumors – including targeted therapies and immuno-oncology – Jazz is advancing novel investigational therapies that target specific proteins like HER2 and important signaling pathways such as the RAS-RAF-MAPK pathway."
Notable presentations include:
- A poster presentation featuring progression-free survival (PFS) and duration of response (DoR) results from a Phase 1b/2 study of zanidatamab plus chemotherapy in combination with tislelizumab for the first-line treatment of HER2-positive gastric/gastroesophageal junction adenocarcinoma (G/GEJC). The study, sponsored by BeiGene, Ltd., showed zanidatamab plus chemotherapy and tislelizumab produced antitumor activity with a confirmed objective response rate (ORR) of
75.8% and median PFS of 16.7 months; and safety was consistent with previous findings.1 - A poster presentation featuring quality-of-life data from a Phase 2b study of zanidatamab for the second-line treatment of HER2-amplified biliary tract cancers (BTC), finding that patients with HER2-positive BTC who responded to zanidatamab reported improved health-related quality of life (HRQoL) compared with baseline. Overall, zanidatamab led to a meaningful clinical benefit, which may reduce disease burden and potentially result in improved patient HRQoL compared with baseline.2
- A mini oral presentation highlighting results of the Phase 1/2 LUPER study evaluating the efficacy of lurbinectedin in combination with pembrolizumab for the second-line treatment of small cell lung cancer (SCLC), which includes the following data: preliminary ORR of
46.4% , median DoR of 11.4 months, median PFS of 5.3 months and median OS of 11.1 months; the combination resulted in a manageable safety profile.3

About Zanidatamab
Zanidatamab is an investigational bispecific antibody that can simultaneously bind two non-overlapping epitopes of HER2, known as biparatopic binding. This unique design results in multiple mechanisms of action including dual HER2 signal blockade, increased binding and removal of HER2 protein from the cell surface, and potent effector function leading to encouraging antitumor activity in patients. Zanidatamab is being developed in multiple clinical trials as a targeted treatment option for patients with solid tumors that express HER2. Zanidatamab is being developed by Jazz and BeiGene, Ltd. (BeiGene) under license agreements from Zymeworks, which first developed the molecule.
The U.S. Food and Drug Administration (FDA) has granted Breakthrough Therapy designation for zanidatamab in patients with previously treated HER2 gene-amplified biliary tract cancers (BTC), and two Fast Track designations for zanidatamab: one as a single agent for refractory BTC and one in combination with standard of care chemotherapy for first-line gastroesophageal adenocarcinoma (GEA). Additionally, zanidatamab has received Orphan Drug designations from FDA for the treatment of BTC and GEA, as well as Orphan Drug designation from the European Medicines Agency for the treatment of gastric cancer. Zanidatamab was also granted Breakthrough Therapy designation from the Center for Drug Evaluation (CDE) in China.
About Zepzelca® (lurbinectedin)
Zepzelca is an alkylating drug that binds guanine residues within DNA. This triggers a cascade of events that can affect the activity of DNA binding proteins, including some transcription factors, and DNA repair pathways, resulting in disruption of the cell cycle and eventual cell death.4
The FDA approved Zepzelca under accelerated approval in June 2020 for the treatment of adult patients with metastatic SCLC with disease progression on or after platinum-based chemotherapy. The approval is based on overall response rate (ORR) and duration of response demonstrated in an open-label, monotherapy clinical study. In December 2021, Jazz and PharmaMar announced the initiation of LAGOON, a confirmatory Phase 3 clinical trial of Zepzelca for the treatment of patients with relapsed small cell lung cancer. If positive, LAGOON could confirm the benefit of Zepzelca in the treatment of small cell lung cancer (SCLC) when patients progress following 1L treatment with a platinum-based regimen and support full approval in the U.S.
Zepzelca is a prescription medicine used to treat adults with SCLC that has spread to other parts of the body (metastatic) and who have received treatment with chemotherapy that contains platinum, and it did not work or is no longer working. Zepzelca is approved based on response rate and how long the response lasted. Additional studies will further evaluate the benefit of Zepzelca for this use.

About JZP815
JZP815 is an investigational pan-RAF kinase inhibitor that was discovered and developed using state-of-the-art screening methodologies and medicinal chemistry. JZP815 targets specific components of the mitogen-activated protein kinase (MAPK) pathway that, when activated by oncogenic mutations, can be a frequent driver of human cancer. JZP815 potently inhibits both monomer- and dimer-driven RAF signaling (e.g., RAS-induced), prevents paradoxical pathway activation induced by BRAF selective inhibition, and is active against class 1, class 2, and class 3 BRAF mutants, as well as BRAF fusions and CRAF mutants. JZP815 is not currently approved for use anywhere in the world. JZP815 is part of Jazz's growing early-stage R&D pipeline focused on solid tumors and targeted therapy.
