Zolbetuximab, sold under the brand name Vyloy, is a monoclonal antibody used for the treatment of gastric cancer. [4] It is a claudin 18.2-directed cytolytic antibody against isoform 2 of Claudin-18. [4] Zolbetuximab was developed by Ganymed Pharmaceuticals. [7] Astellas Pharma acquired the rights to zolbetuximab in December 2016, when it acquired Ganymed Pharmaceuticals. [8]
Zolbetuximab was approved for medical use in Japan in March 2024, [9] in the European Union in September 2024, [5] and in the United States in October 2024. [10] [11] The US Food and Drug Administration (FDA) considers it to be a first-in-class medication. [12]
Zolbetuximab is indicated in combination with fluoropyrimidine- and platinum-containing chemotherapy for the first-line treatment of adults with locally advanced unresectable or metastatic human epidermal growth factor receptor 2 (HER2)-negative gastric or gastroesophageal junction adenocarcinoma whose tumors are claudin (CLDN) 18.2 positive. [4] [5] [10]
The most common adverse reactions include nausea, vomiting, decreased appetite, weight loss, neutropenia (low levels of neutrophils, a type of white blood cell that fights infections), fever, hypoalbuminemia (low levels of albumin, a blood protein), and peripheral edema (swelling, especially of the ankles and feet). [5]
Other side effects include hypertension (high blood pressure), dyspepsia (indigestion), chills, salivary hypersecretion (excess production of saliva), infusion-related reactions and hypersensitivity (allergic reactions). [5]
Zolbetuximab has been tested in two phase III clinical trials for gastric cancer, SPOTLIGHT and GLOW. [13] [14] A combined analysis of the two trials confirmed that zolbetuximab, when added to chemotherapy, improved progression-free survival and overall survival for patients with HER2-negative, locally advanced unresectable or metastatic gastric or gastroesophageal junction adenocarcinoma whose tumors were positive for claudin 18.2. [15]
In Japan, zolbetuximab is approved for the treatment of people with CLDN18.2-positive, unresectable, advanced, or recurrent gastric cancer. [9] [16]
In July 2024, the Committee for Medicinal Products for Human Use of the European Medicines Agency adopted a positive opinion, recommending the granting of a marketing authorization for the medicinal product Vyloy, intended for the treatment of gastric or gastro-esophageal junction adenocarcinoma. [5] [17] The applicant for this medicinal product is Astellas Pharma Europe B.V. [5] Vyloy was authorized for medical use in the European Union in September 2024. [5] [6]
Zolbetuximab was approved for medical use in the United States in October 2024. [10] [11]
Zolbetuximab is the international nonproprietary name. [18]
Zolbetuximab is sold under the brand name Vyloy. [4]
