Describes the nature of a clinical study. Types include: Observational study — observes people and measures outcomes without affecting results. Interventional study clinical trial — studies new tests, treatments, drugs, surgical procedures or devices. Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best. In the later phase phase 3, researchers study whether the treatment works better than the current standard therapy. They also compare the safety of the new treatment with that of current treatments. Phase 3 trials include large numbers of people to make sure that the result is valid.

Eosinophilic esophagitis EoE is a benign, chronic disorder of the esophagus characterized by intermittent solid food dysphagia and impaction, as well as chest pain and heartburn. Left untreated, this disorder is also associated with esophageal remodeling and stricture formation. Current guidelines recommend performing endoscopic biopsy to obtain four to six tissue samples from the esophageal mucosa to confirm diagnosis. A positive diagnosis is defined by eosinophilic infiltration of at least 15 eosinophils eos per high-power field HPF. Treatment of EoE is directed at reducing inflammation and reversing esophageal fibrosis that develops as a result of long-term inflammatory activity. Commonly used treatment options for EoE include dietary, pharmacologic and endoscopic intervention, each of which has known advantages and disadvantages. Given that dietary therapy actually prevents esophageal inflammation, is associated with lower costs and has fewer known side effects than currently available pharmacologic and endoscopic interventions, this approach is gaining gradual acceptance as a treatment for EoE in both children and adults.
