contraception, as defined in the study restriction section. If necessary, women of
non-child bearing potential (i.e. post-menopausal or surgically sterile e.g. tubal
ligation or hysterectomy or bilateral oophorectomy) will be confirmed. Postmenopausal

Summary
Brief summary
This is a randomized, double-blinded, placebo-controlled adaptive, dose finding study to
investigate the safety, tolerability, PK, PD and efficacy of single and repeat intravenous
infusions of GSK315243A in patients with active rheumatoid arthritis. The study is divided
into 2 parts: Part A is an adaptive, dose finding phase which will provide safety,
tolerability, PK and PD on single intravenous infusions. Part B is a repeat dose phase which
will provide safety, tolerability, PK, PD and efficacy following repeat intravenous infusions
of a selected dose level.
