Study Endpoints

Primary Endpoints

Number of Participants With Any Treatment-emergent Adverse Event (TEAE)
up to Week 10

An AE is defined as any untoward medical occurrence in a participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable or unintended sign (including a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product. A TEAE is defined as an adverse event (AE) with an onset after the first dose of study drug or an existing event that worsened after the first dose during the study.

Number of Participants With Any ≥Grade 3 TEAE
up to Week 10

An AE is defined as any untoward medical occurrence in a participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable or unintended sign (including a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product. A TEAE is defined as an adverse event (AE) with an onset after the first dose of study drug or an existing event that worsened after the first dose during the study. AEs were graded for severity using the the Common Terminology Criteria for Adverse Events, version 5.0 (CTCAE v.5). CTCAE grades were scored as: Grade 1 = mild; Grade 2 = moderate; Grade 3 = severe or medically significant; Grade 4 = life threatening; Grade 5 = death related to the AE.

Number of Participants With Clinically Meaningful Changes From Baseline in Vital Signs
up to Week 10

Clinical meaningfulness was determined by the investigator.

Number of Participants With Clinically Meaningful Changes From Baseline in Electrocardiograms (ECGs )
up to Week 10

Clinical meaningfulness was determined by the investigator.

Number of Participants With Clinically Meaningful Changes From Baseline in Clinical Hematology, Chemistry, or Coagulation Parameters
up to Week 10

Clinical meaningfulness was determined by the investigator.

Safety and tolerability of EP262
Measured from Day 1 to End of Study or Early Termination (up to 12 weeks)

Frequently asked questions about EP262

What is EP262 used for?

EP262 is an investigational oral small molecule being developed for inflammatory skin conditions, specifically atopic dermatitis and chronic inducible urticaria. It is in Phase 2 clinical development and has not been approved by the FDA. Incyte Corporation is evaluating it as a potential treatment for these dermatologic indications.

What does EP262 target?

EP262 targets MRGPRX2, a G protein-coupled receptor. By targeting this receptor, EP262 is designed to modulate mast cell activation, which is relevant to inflammatory skin conditions such as atopic dermatitis and chronic inducible urticaria.

Who is developing EP262?

EP262 is being developed by Incyte Corporation, which trades on the Nasdaq under the ticker INCY. Incyte is the sponsor of the clinical trials evaluating EP262 in atopic dermatitis and chronic inducible urticaria.

What phase is EP262 in?

EP262 is in Phase 2 clinical development. A Phase 2a trial in atopic dermatitis has been completed, and a Phase 1b trial in chronic inducible urticaria has also been completed. EP262 is investigational and has not been approved by the FDA.

What clinical trials is EP262 in?

EP262 has been studied in two completed trials: NCT06144424, a Phase 2a randomized, double-blind, placebo-controlled study in atopic dermatitis, and NCT06050928, a Phase 1b open-label study in chronic inducible urticaria. Both trials enrolled adults and were conducted in multiple countries.

Is EP262 the same as Oral EP262?

Yes, Oral EP262 is another name for EP262. Both refer to the same investigational small molecule developed by Incyte Corporation for atopic dermatitis and chronic inducible urticaria.
