Health authority | United States: Food and Drug Administration |
Study type | Interventional |
The purpose of this study is to estimate the effect of anakinra, 100 mg once daily (QD), on the development of an anti-tetanus antibody response in subjects with RA after vaccination with a tetanus and diphtheria toxoids injection. In addition, this study will evaluate the general safety profile of therapy with anakinra, 100 mg QD, in subjects with RA after vaccination with a tetanus and diphtheria toxoids injection.
