Bilastine Updosing - Characterization of Underlying Mechanisms (BUCUM)

May 30, 2012 updated by: Karoline Krause, Charite University, Berlin, Germany

Double-blind, Triple Cross-over, Placebo-controlled Study to Assess the Efficacy, Mechanisms, and Safety of Treatment With Bilastine 20 mg, 40 mg and 80 mg in Cold Contact Urticaria (CCU)

This is a double-blind, triple cross-over, placebo-controlled study to assess the efficacy, mechanisms, and safety of treatment with the antihistamine bilastine in patients with cold contact urticaria (CCU).

Efficacy is primarily assessed by a change in critical stimulation time thresholds (CSTT) and critical temperature thresholds (CTT) after treatment with different dosages of bilastine (20 mg, 40 mg, 80 mg). Following a baseline period of 2-4 weeks, patients are randomized to either group A or group B. In group A they are given bilastine 20 mg, 40 mg, placebo and bilastine 80 mg for 7 days each followed by a 14-day washout period at a time. In group B they are given bilastine 80 mg, placebo, 40 mg and 20 mg for 7 days each followed by a 14-day washout period at a time. CSTT and CTT testings are performed at each of 6 visits, skin microdialysis for the assessment of mast cell mediators is performed at V2, V3 and V6. Visits for investigator's assessments are scheduled at day -14 to -28, day 0, day 7, day 28, day 49, and day 70. Overall a max. of 20 subjects with cold contact urticaria will be enrolled.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All
