24 Weeks Double-blind Randomized Placebo-controlled Trial to Evaluate Efficacy, PK, Safety of LOU064 in Adolescents (12 - <18) With CSU and Inadequate Response to H1-antihistamine Followed by Optional 3 Years Open-label Extension and an Optional 3 Years Safety Long-term Treatment-free Follow-up
NCT05677451 · View on ClinicalTrials.gov ↗
Study Summary
The purpose of this trial is: 1. to assess the efficacy, pharmacokinetics, and safety of remibrutinib vs. placebo in adolescents from 12 to \< 18 years of age suffering from chronic spontaneous urticaria inadequately controlled by H1-antihistamines 2. to collect long-term efficacy, safety and tolerability data on remibrutinib in adolescents after having completed 24 weeks of treatment 3. to collect safety data in this population for up to three years after the last dose of study treatment

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT05677451
The ClinicalTrials.gov registry entry for NCT05677451 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 100 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Novartis Pharmaceuticals, which has 792 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 Chronic Spontaneous Urticaria appearing as the primary indexed condition, and to 2 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: NCT05677451 reports 20 study locations spanning 17 distinct geographic areas — top geographies include Buenos Aires, California, Florida. 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.
