Kineret (Anakinra), in Adult Patients With Colchicine-Resistant Familial Mediterranean Fever (FMF)
Recruitment status was Recruiting
FMF is the most common periodic fever with a worldwide patient population estimated as 150,000, mainly located in the Eastern Mediterranean basin. colchicine is the established therapy of choice ,however, around 20.000 patients worldwide fail to respond or cannot tolerate therapeutic doses, thereby suffering from recurrent debilitating, severe, painful attacks of peritonitis, pleuritis and synovitis and are at risk to die from reactive amyloidosis .Mutation-induced reduction in pyrin/ marenostrin activity is thought to underlie the disease by leading to NALP3 inflammasome activation ,and thereby to IL-1β related burst of inflammation.
The IL-1 receptor antagonist Kineret (Anakinra), seems to be the most appropriate response to the uncontrolled IL-1β elevation. Indeed, an increasing number of reports over the last few years indicate a good response to Kineret (Anakinra), in colchicine-resistant FMF ,also in children ,however, no controlled study has thoroughly evaluated the efficacy and safety of this treatment.
The study aims to run at the FMF centre in Sheba Medical Center, covering more than 10,000 patients. The study will evaluate the effect of recombinant IL-1 receptor antagonist, Kineret (Anakinra), on the frequency of FMF attacks in patients that, despite maximum tolerable dose of colchicine, present with more than one attack per month.
The study is designed as a randomised, placebo-controlled, double-blind study. 50 patients will be randomised to treatment with either Kineret (Anakinra), or placebo treatment for 4 months.

|Official Title:||A Randomized Placebo-Controlled Study of the Efficacy and Safety of Kineret (Anakinra), in Adult Patients With Colchicine-Resistant Familial Mediterranean Fever|
- Number of patients with less than a mean of one FMF attack per month [ Time Frame: 4 months ] [ Designated as safety issue: No ]Total number of FMF attacks in abdominal, thoracic, skin or joint locations during the observational period (4 months) as recorded in the patient diary, devided by 4 for each patient will result in number of attacks per one month. The number of patients with less than 1 attack per month will be compared between the 2 study groups
- Number of serious adverse events [ Time Frame: 4 months ] [ Designated as safety issue: Yes ]
Secondary endpoint is defined as total number of serious adverse events per 4 months in each study group. SAE is defined as an adverse event that meets one or more of the following criteria/outcomes:
- Life-threatening (i.e., at immediate risk of death)
- In-patient hospitalization or prolongation of existing hospitalization
- Persistent or significant disability/incapacity
- Congenital anomaly/birth defect

|Estimated Primary Completion Date:||December 2014 (Final data collection date for primary outcome measure)|
Placebo Comparator: Vehicle
•Patients randomized to placebo will receive syringes identical to active drug (100 mg prefilled syringes for subcutaneous injection) filled with drug vehicle
Experimental: Kineret (Anakinra)
Patients randomized to active drug will receive Kineret (Anakinra), 100 mg prefilled syringes for subcutaneous injection, once a day for 4 months. The syringes will arrive relabeled from the supplier (SOBI) to Sheba Medical Center. They will be stored at the PI's store room in a temperature controlled refrigerator.
