Primary Outcome Measures
NameTimeMethod
Main Objective: To assess the efficacy and safety of dose regimens of ALX-0061 monotherapy administered s.c. to subjects with active RA;Secondary Objective: To assess the effects of ALX-0061 on quality of life, PK, PD, and immunogenicity of ALX 0061 and to explore potential dose regimens for ALX 0061 monotherapy, based on safety and efficacy, for further clinical development. <br><br>To obtain parallel descriptive information concerning the efficacy and safety of tocilizumab (TCZ) s.c. in the same clinical trial RA population.<br>;Primary end point(s): The proportion of subjects achieving an ACR20 response at Week 12.;Timepoint(s) of evaluation of this end point: Week 12
