Study Summary

This trial is testing a new drug, dupilumab, to see if it is safe and effective in treating adults with chronic pruritus of unknown origin (CPUO). The trial has two parts, study A and study B. In both parts, participants will use a non-sedative antihistamine and an emollient for 4 weeks before starting the trial medication. In study A, participants will be treated with dupilumab or placebo for 24 weeks, followed by a 12-week follow-up period. In study B, participants will be treated with dupilumab or placebo for 12 weeks, followed by a 12

Who is the study for?
Adults aged 18-90 with severe, chronic itching of unknown origin that affects at least two body areas (legs, arms, or trunk) and have not found relief from previous treatments. Participants must score 'severe' on itch severity scales and be in good health otherwise. Those with certain infections, immune deficiencies, severe kidney failure, hypersensitivity to antihistamines or a history of cancer within the last five years are excluded.Check my eligibility
What is being tested?
The trial is testing Dupilumab's effectiveness for treating chronic itching without a known cause over a period of either 12 or 24 weeks. It involves two parallel studies where participants also use non-sedative antihistamines and moisturizers. They're randomly assigned to receive either Dupilumab or a placebo in addition to their current regimen.See study design
What are the potential side effects?
While specific side effects for this trial aren't listed here, common side effects of Dupilumab may include injection site reactions (like redness), eye inflammation or irritation, cold sores in your mouth or throat area.
