Summary
This open-label, randomized, cross-over study evaluated the effect of tocilizumab (TCZ) on
the pharmacokinetics and pharmacodynamics of a common oral contraceptive (OC) in female
patients with active rheumatoid arthritis (RA) and in healthy female volunteers of child
bearing age. The RA patients received OC in combination with TCZ, whereas the healthy
volunteers received OC only. The RA patients received OC in 3 cycles of 21 days each; TCZ 8
mg/kg was administered once as an intravenous infusion on the first day of Cycle 2. The
healthy volunteers received OC for only one 21-day cycle.
