Efficacy and Safety of Subcutaneous Dupilumab for the Treatment of Adult Participants With Chronic Pruritus of Unknown Origin (CPUO) (LIBERTY-CPUO-CHIC)
NCT05263206 · View on ClinicalTrials.gov ↗
Study Summary
The main objective of the study is to assess efficacy and safety of dupilumab given up to 24 weeks in adults with CPUO. This is a master protocol which includes 2 parallel-treatment, double-blind, 2- arm Phase 3 staggered studies of similar design (Study A and Study B) in male and female participants aged 18 to 90 years with CPUO. Study B design was to be adapted based on the results of Study A. For both Study A and B, after an up-to-4-week screening period, participants with severe pruritus (worst-itch numerical rating scale \[WI-NRS ≥7) will enter a 4-week run-in period and will be treated with a non-sedative antihistamine and an emollient (moisturizer). Participants with severe pruritus (WI-NRS ≥7) at baseline will be randomized (1:1) to be treated for 24 weeks with either dupilumab or matching placebo in addition to their non-sedative antihistamine and emollient regimen. The treatment period for both study A and B will be followed by a 12-week follow-up period.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT05263206
The ClinicalTrials.gov registry entry for NCT05263206 describes a study currently listed as recruiting. It is categorized as Phase 3, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 284 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Sanofi, which has 275 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Pruritus appearing as the primary indexed condition, and to 3 interventions — of which Placebo is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT05263206 reports 20 study locations spanning 15 distinct geographic areas — top geographies include California, Florida, Georgia. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
