Effect of Interleukin-1 Receptor Antagonist on Inhalation of 20,000 EU Clinical Ctr Reference Endotoxin in Normal Volunteers (Kintox)
The investigators want to see if healthy people who are given 2 doses of a medication called anakinra, which is used to treat moderate to severe rheumatoid arthritis, (RA) and then exposed to a form of air pollution, called Endotoxin, have less inflammation with the medication. Endotoxin is believed to be one of the causes of asthma attacks.

|Official Title:||A Study of the Effect of Interleukin-1 Receptor Antagonist on Inhalation of 20,000 EU Clinical Center Reference Endotoxin in Normal Volunteers|
- blockade of IL-1 β will suppress neutrophil response to challenge with 20,000 EU CCRE [ Time Frame: 6 hours after inhalation of CCRE ] [ Designated as safety issue: Yes ]The primary endpoints for this study will be a) safety assessments of anakinra with CCRE inhalation and b) the post CCRE challenge percentage of neutrophils (%PMN) in airway sputum during the anakinra treatment period compared to the placebo treatment period.
|Study Start Date:||October 2011|
|Study Completion Date:||July 2013|
|Primary Completion Date:||July 2013 (Final data collection date for primary outcome measure)|
Active Comparator: Anakinra
All subjects will undergo 2 CCRE challenges. Each subject will be given either anakinra or placebo prior to CCRE challenge
Active treatment will consist of 2 doses of 1 mg/kg up to 100 mg of anakinra SQ injection.
Placebo Comparator: Placebo
Normal saline injection
Injection of NS
