Study Description

Brief Summary:

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

Condition or disease	Intervention/treatment	Phase
Pruritis	Drug: INCB039110	Phase 2

Detailed 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.

Study Design

• Study Type: Interventional (Clinical Trial)
• Actual Enrollment: 0 participants
• Intervention Model: Single Group Assignment
• Masking: None (Open Label)
• Primary Purpose: Treatment
• Official Title: Relieving Chronic Itch : Oral Medication
• Estimated Study Start Date: August 2018
• Actual Primary Completion Date: October 9, 2018
• Actual Study Completion Date: October 9, 2018

Arms and Interventions

Arm	Intervention/treatment
Experimental: INCB039110; INCN039110 400 mg QD for 20 weeks. Subjects without clinical response after four weeks will increase to 600mg QD.	Drug: INCB039110; All subjects will receive 400 mg PO QD for 12 weeks. If no clinical response after four weeks, dose will be increased to 600 mg PO QD. Total duration of subject participation will be six study visit over 20 weeks.

7. Use of any prohibited medications (see Section 5.8) within 14 days or 5 half-lives (whichever is longer) of the baseline visit

8. Current clinically significant cardiovascular, respiratory, neurologic, hepatic, hematopoietic, renal gastrointestinal, endocrine or metabolic dysfunction unless currently controlled and stable, including (but not limited to) the following:

   1. Positive for hepatitis C antibody test (anti-HCAbF) with detectable RNA
   2. Positive for hepatitis B surface antigen (HBsAg) or hepatitis B core antibody (HBcAb);
   3. Positive for HIV (DUO test, p24 antigen)
9. Active malignancy
10. Subjects with a history of malignancy, except for the following adequately treated, nonmetastatic malignancies: basal cell skin cancer, squamous cell carcinomas of the skin, or in situ cervical cancer
11. History (including family history) or current evidence of congenital long QT syndrome or known acquired QT prolongation
12. Exposure to any investigational medication, including placebo, within 60 days of the Baseline Visit
13. History of intolerance and/or hypersensitivity to medications similar to INCB039110 (e.g., Xeljanz)
14. Participation in a previous INCB39110 trial

15. Subjects with severely impaired liver function (Child-Pugh Class C) or end-stage renal disease on dialysis or at least 1 of the following:

    1. Serum creatinine > 1.5 mg/dL;
    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
18. Subjects taking potent systemic CYP3A4 inhibitors or fluconazole within 2 weeks or 5 half-lives, whichever is longer, before the baseline visit
