The US Food and Drug Administration has approved a new drug for the treatment of eosinophilic esophagitis (EoE), a chronic, immune-mediated inflammatory disease that can cause difficulty swallowing and affect individuals of any age. The drug, Eohilia, is an oral suspension of budesonide which was developed by Takeda Pharmaceutical Co Ltd and shown to be effective in two trials of adult and paediatric patients. The drug was compared with a placebo and administered for a period of 12 weeks. The first study enrolled patients 11 to 56 years of age and the second, 11 to 42 years of age.
