Summary

Cold contact urticaria (CCU) is a frequent form of physical urticaria that is characterized by the development of wheal and flare type skin reactions due to the release of histamine and other proinflammatory mast cell mediators following exposure of the skin to cold. Typically, symptoms occur within minutes after cold contact, including exposure to cold air, liquids or objects and are limited to cold exposed skin areas.

The investigators postulate that there is an overlap between acquired cold urticaria and cold-induced autoinflammatory syndromes, and that cold urticaria patients unresponsive to antihistamines will benefit from IL-1 targeting treatment strategies.

This study will evaluate the efficacy and safety of the IL-1 transfusion protein rilonacept in patients with cold contact urticaria who could not be successfully treated with first-line medication such as antihistamines.

This is a double-blind placebo-controlled parallel group phase II study of the efficacy and safety of rilonacept in subjects with CCU. A total of 20 patients will be included by the Urticaria specialty clinics of ACC. The total duration of the study course for each patient is 14 weeks and is divided in:

1. Screening period (2 weeks, days -14-0)
2. Placebo-controlled double-blind phase (Part A, 6 weeks, days 0-42)
3. Open label phase (Part B, 6 weeks, days 42-84) All eligible patients will be randomized (1:1 randomization) to one of two groups: 1) Rilonacept 160mg/week or 2) Placebo, and will receive the respective dose subcutaneously. Following the placebo-controlled double-blind phase patients will enter the open-label phase and receive rilonacept open-label treatment (160mg or 320mg depending on treatment response during part A).
