Jazz Pharmaceuticals Advances Zanidatamab for Biliary Tract Cancer
Jazz Pharmaceuticals Gains Positive Opinion for Zanidatamab
Jazz Pharmaceuticals plc (Nasdaq: JAZZ) has made significant strides towards addressing a critical need in cancer care. The Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has issued a positive opinion recommending the conditional marketing authorization for zanidatamab. This groundbreaking treatment is aimed at adults suffering from unresectable locally advanced or metastatic HER2-positive biliary tract cancer (BTC), a disease characterized by poor prognosis.
Importance of CHMP's Recommendation
Robert Iannone, MD, M.S.C.E., the executive vice president and chief medical officer at Jazz Pharmaceuticals, expressed optimism regarding this development. As he noted, the positive CHMP opinion is a crucial advancement for patients and healthcare providers confronting the challenges posed by HER2-positive biliary tract cancers, which are rare yet aggressive. If this therapy receives formal approval, it would represent the first HER2-targeted treatment authorized for use in this difficult-to-treat cancer cohort in the European Union (EU).
Clinical Trial Insights
The recommendation from CHMP is supported by the results of the Phase 2b HERIZON-BTC-01 trial. This trial evaluated the efficacy of zanidatamab among previously treated patients suffering from inoperable, advanced, or metastatic HER2-positive biliary tract cancer. Given that biliary tract cancers represent less than 1% of all human cancers yet are on the rise, new treatment options like zanidatamab are incredibly essential.
The Burden of Biliary Tract Cancer
Biliary tract cancers, which include conditions such as cholangiocarcinoma and gallbladder cancer, are often diagnosed at more advanced stages. This delay occurs partly because the early symptoms of the disease can be vague and indistinct, limiting the possibility of curative surgeries and effective treatment. Historically, chemotherapy and immunotherapy have been the primary treatment modalities, but disease progression remains common, highlighting the urgent need for innovative therapies like those being developed by Jazz Pharmaceuticals.
Understanding HER2 and Its Implications
Research has shown that HER2 overexpression in biliary tract cancer is associated with a distinct molecular subtype that correlates with poorer patient outcomes compared to HER2-negative forms of cancer. Despite this, there are currently no approved HER2-targeting treatments in the EU, making the development of zanidatamab particularly timely and significant.
Next Steps in the Approval Process
The CHMP recommendation is now in the hands of the European Commission, which will review the evidence and decide on the approval for zanidatamab’s conditional marketing authorization across the EU and member states. If granted, it would pave the way for improved treatment options for patients suffering from this tumultuous disease.
About Zanidatamab
Zanidatamab is a dual HER2-targeted bispecific antibody. It works by binding to the extracellular domains of the HER2 receptor, leading to effective internalization and a reduction of receptor levels on the cell surface. These actions, combined with its ability to induce mechanisms such as complement-dependent cytotoxicity and antibody-dependent cellular cytotoxicity, result in significant tumor growth inhibition.
Jazz Pharmaceuticals' Mission

The company has a broad portfolio that spans sleep disorders, epilepsy, and an increasing number of cancer treatments. With a mission rooted in patient care and scientific innovation, Jazz continues to lead advancements in oncology and neuroscience.
