HAMPTON, NJ, USA I July 06, 2023 I Celldex Therapeutics, Inc. (NASDAQ:CLDX) today announced that the first patient has been dosed in the Company’s Phase 2 subcutaneous study of barzolvolimab in eosinophilic esophagitis (EoE). EoE is the most common type of eosinophilic gastrointestinal disease, a chronic inflammatory disease of the esophagus. Several studies have suggested that mast cells may be an important driver in this disease. Barzolvolimab is a humanized monoclonal antibody that specifically binds the receptor tyrosine kinase KIT with high specificity and potently inhibits its activity, which is required for the function and survival of the mast cell.
“There is a growing body of literature that suggests that eosinophilic esophagitis may be a misnomer for this difficult to treat disease and that other cell types, including mast cells, may play an important role in the disease process,” said Diane C. Young, M.D, Senior Vice President and Chief Medical Officer of Celldex Therapeutics. “This is further supported by the finding that mast cells are present in the biopsy tissue of some patients who continue to suffer from EoE even after eosinophils have been fully depleted. We look forward to exploring the role of our mast cell depleting agent, barzolvolimab, in this setting and believe learnings from this study may inform expanded development into other GI disorders in the future.”
The randomized, double-blind, placebo-controlled, parallel group Phase 2 study is evaluating the efficacy and safety profile of subcutaneous barzolvolimab in patients with active EoE. Approximately 60 patients will be randomly assigned on a 1:1 ratio to receive subcutaneous injections of barzolvolimab at 300 mg every 8 weeks or placebo during a 16-week placebo-controlled treatment phase. Patients then enter a 12-week active treatment phase, in which all patients will receive barzolvolimab 300 mg every 8 weeks. Patients then enter a follow-up phase for an additional 16 weeks. The primary endpoint of the study is reducing esophageal intraepithelial infiltration of mast cells as assessed by peak esophageal intraepithelial mast cell count. Secondary endpoints include the reduction of symptoms of dysphagia and esophageal intraepithelial infiltration of eosinophils and safety. When all clinical trial sites are open, the study will include approximately 60 clinical trial centers across 8 countries, including the United States.
EoE, the most common type of eosinophilic gastrointestinal disease, is a chronic inflammatory disease of the esophagus characterized by the infiltration of eosinophils. This chronic inflammation can result in trouble swallowing, chest pain, vomiting and impaction of food in the esophagus – a medical emergency. Currently, there are limited treatment options for EoE. Several studies have suggested that mast cells may be an important driver in the disease. Given the lack of effective therapies for EoE and barzolvolimab’s potential as a mast cell depleting agent, Celldex believes EoE is an important indication for study.

About Barzolvolimab
Barzolvolimab is a humanized monoclonal antibody that binds the receptor tyrosine kinase KIT with high specificity and potently inhibits its activity. KIT is expressed in a variety of cells, including mast cells, which mediate inflammatory responses such as hypersensitivity and allergic reactions. KIT signaling controls the differentiation, tissue recruitment, survival and activity of mast cells. In certain inflammatory diseases, such as chronic urticaria, mast cell activation plays a central role in the onset and progression of the disease.
About Celldex Therapeutics, Inc.
Celldex is a clinical stage biotechnology company dedicated to developing monoclonal and bispecific antibodies that address devastating diseases for which available treatments are inadequate. Our pipeline includes antibody-based therapeutics which have the ability to engage the human immune system and/or directly affect critical pathways to improve the lives of patients with inflammatory diseases and many forms of cancer.
