Monoclonal antibodyTargetAuthorDesignStudy populationDosePrimary outcome
DupilumabIL-4RαDellon et al. [18]Placebo-controlled, phase 3 RCTn 240 (adolescents and adults)300 mg s.c. every week or every 2 weeks or placebo

At week 24 histologic remission (≤ 6 eosinophils per HPF) and the change from baseline in the DSQ score

DupilumabIL-4RαHirano et al. [19]Placebo-controlled, phase 2 RCTn 47 (adults)300 mg or placebo weekly

At week 10 change from baseline in SDI, PRO score; histologic features of EoE (peak esophageal intraepithelial eosinophil count and EoE histologic scores)

Dectrekumab (QAX576)IL-13Rothenberg et al. [20]Placebo-controlled, phase 2 RCTn 23 (adults)6 mg/kg monthly or placeboAt week 12 responder rate for a greater than 75% decrease in peak eosinophil counts
Cendakimab (RPC4046)IL-13Hirano et al. [21]Placebo-controlled, phase 2 RCTn 99 (adults)180 mg, 360 mg, or placebo weeklyAt week 16 change in mean esophageal eosinophil count in the 5 HPFs
MepolizumabIL-5Strauman et al. [24]Placebo-controlled, phase 2 RCTn 11 (adults)750 mg × 2 or placebo weekly, followed by 2 more infusions of 1,500 mg of drug or placebo in lack of histological responseReduce peak esophageal eosinophilia to < 5 eos/HPF as assessed by histology in adults with active EoE
MepolizumabIL-5Assa’ad et al. [25]Phase 2 RCTn 59 (children)3 infusions of 0.55, 2.5, or 10 mg/kg monthly

At week 12 proportion of patients

with a peak esophageal intraepithelial eosinophil count of < 5 per HPF; safety, tolerability, pharmacokinetics

ReslizumabIL-5Spergel et al. [26]Placebo-controlled, phase 2 RCTn 227 (children and adolescents)4 infusions of 1, 2, or 3 mg/kg monthly or placeboAt week 15 changes in peak esophageal eosinophil count and in the physician’s global assessment score
OmalizumabIgEClayton et al. [29]Placebo-controlled, phase 2 RCTn 30 (adolescents and adults)0.016 mg/kg per IgE every 2–4 weeks

At week 12 decrease in esophageal

eosinophil content
