Clinical Trial Summary

This study evaluates the effect of twice daily dose of INCB39110 in the treatment of itch in adults.

Description:

Chronic idiopathic itch accompanies low-grade skin inflammation. These inflammatory features are associated with cytokine production which signal through the common JAK1-STAT pathway. It is therefore theorized that a selective JAK1 inhibitor such as INCB039110 may provide relief of itch symptom.

2. Alanine aminotransferase or aspartate aminotransferase = 1.5 × upper limit of normal

16. Anyone affiliated with the site or sponsor and/or anyone who may consent under duress

17. Any other sound medical reason as determined by the Investigator including any condition which may lead to an unfavorable risk-benefit of study participation, may interfere with study compliance or may confound study results
