Muckle-Wells Syndrome clinical trials

A Pilot Study of XOMA 052 in Familial Cold Autoinflammatory Syndrome / Muckle-Wells Syndrome and Behcet's Disease

Background: - Autoinflammatory diseases are illnesses that produce episodes of inflammation such as fever, rash, or joint swelling. Some of these diseases can be treated with medications that block the body's reaction to a protein called IL-1, which may be part of the cause of the inflammation. IL-1 blocking agents are very helpful in treating autoinflammatory diseases and have become the standard of care for treatment for some of these diseases. However, more research is needed on related diseases that may be treated with new and currently used IL-1 blocking agents. - XOMA 052 is an experimental drug that is currently being tested as a possible treatment for type 2 diabetes. Initial studies have shown that XOMA 052 neutralizes a specific kind of IL-1, and is also active against certain indicators of inflammation. Researchers are interested in determining whether XOMA 052 can be used to treat autoinflammatory and related diseases. Objectives: - To determine the effectiveness of XOMA 052 as a treatment for inflammation in adults with the autoinflammatory diseases Familial Cold Autoinflammatory Syndrome (FCAS)/Muckle-Wells Syndrome (MWS) and Behcet's Disease. Eligibility: - FCAS/ MWS: Individuals at least 18 years of age who have a known history of the typical disease. - Behcet's Disease: Individuals at least 18 years of age who have evidence of active disease, such as oral or genital ulcers or eye disease. Design: FCAS/MWS Participants - Participants will have an overnight evaluation of their disease, including optional tests (e.g., eye or skin exams). Participants who currently take medications to treat their symptoms will stop taking the medication and will be monitored by study researchers. At the first flare of symptoms, participants will begin to receive XOMA 052. - Participants will have further tests on days 3, 7, and 10 after the initial dose of XOMA 052. If the disease remains under good control, participants will have a clinical exam every 5 days for up to 10 weeks until another disease flare occurs (determined either by symptoms or by inflammation observed in laboratory studies). If the disease is not well controlled with the initial dose of XOMA 052, participants will have additional doses starting at day 7 until either the disease is controlled or researchers determine that the medication is not effective. - Participants will have the option to continue XOMA 052 treatments for up to 1 year.
