What is eosinophilic esophagitis?

Eosinophilic esophagitis (EoE) is a chronic, immune-mediated disease that affects the esophagus, the tube that connects the mouth to the stomach. It is characterized by the accumulation of eosinophils, a type of white blood cell, in the esophagus. These cells are typically involved in allergic reactions and inflammation, and their presence in the esophagus leads to inflammation and damage to the esophageal lining. 

Ongoing research and a promising pipeline of targeted therapies are fueling innovation and market expansion. Despite challenges such as limited disease understanding and a relatively small patient population, the market shows strong growth potential as more effective therapies enter the market, driving demand and advancing patient care in this evolving therapeutic area.

Eosinophilic Esophagitis Market is expected to be driven by the rising incidence and prevalence of eosinophilic esophagitis and advancements in diagnosis and early detection.

Which regions have the highest prevalence of eosinophilic esophagitis?

• North America

• Europe

• Asia-Pacific

• Latin America

• Rest of the World

     North America as the market leader.

How is EoE diagnosed?

Endoscopy, biopsy, and clinical examination are used in the diagnosis of eosinophilic esophagitis (EoE). First, doctors evaluate symptoms such as chronic heartburn, food impaction, and difficulty swallowing. To visually examine the esophagus for indications of constriction, rings, or inflammation, an upper endoscopy is carried out. The esophagus lining is then biopsied several times to look for the hallmark of EoE, an increased number of eosinophils (a type of white blood cell), under a microscope. Eliminating other potential causes of esophageal eosinophilia, such as infections or acid reflux, is another step in the diagnosis process.

What are the most common symptoms of EoE?

The symptoms of eosinophilic esophagitis (EoE) vary depending on the age of the patient. Common symptoms in children include poor growth, vomiting, abdominal pain, and trouble feeding. Food impaction, or food becoming lodged in the esophagus, chest pain that doesn't go away with antacids, and dysphagia, or trouble swallowing, are the conditions that patients experience more often as they age. Additionally, a lot of adults and teenagers complain of chronic heartburn or sensations similar to acid reflux that don't go away with standard GERD therapies. Chronic esophageal inflammation, which is usually verified by endoscopy and biopsy, frequently coexists with these symptoms.

What factors are driving the growth of the EoE market?

• Rising Prevalence and Incidence: Globally, the number of eosinophilic esophagitis patients is rising due to increased awareness and reporting of the illness, which is growing the patient base and driving market demand.

• Advancements in Diagnosis and Early Detection: Better patient outcomes and prompt treatment are made possible by earlier and more accurate identification made possible by improved diagnostic instruments and methodologies.

• Pipeline of Novel Therapies: A strong pipeline of innovative and targeted therapies under development is driving market growth by addressing unmet medical needs and offering more effective treatment options.

Recent Developments

• November 2024: The European Medicines Agency (EMA) approved Dupixent as the first treatment for young children with eosinophilic esophagitis in the European Union, marking a significant advancement for pediatric patients.
  
  

• February 2024: The U.S. Food and Drug Administration (FDA) granted approval to EOHILIA, the first and only FDA-approved oral therapy for patients aged 11 years and older with eosinophilic esophagitis.
  
  

• February 2024: The FDA expanded the indication for Dupixent, developed by Regeneron and Sanofi, to include children with eosinophilic esophagitis, broadening access to this targeted biologic therapy.

Market Challenges

• Limited Understanding of Disease Pathophysiology: The development of highly focused and curative medicines is hampered by the incomplete understanding of the underlying mechanisms of eosinophilic esophagitis, despite increasing study.

• Limited Patient Pool: Because EoE is an uncommon condition, only a small number of people have been diagnosed. This can limit market potential and the commercial viability of innovative treatments, particularly in areas with lesser diagnostic skills and awareness.
