About the study

This is a Phase 1, open-label, 3-period, single-sequence, crossover study to evaluate potential effects of olokizumab on pharmacokinetics (PK) of selected CYP450 substrates in subjects with Rheumatoid Arthritis (RA).

Who can take part?

You may be eligible to participate in the study if you meet the following criteria:

Inclusion criteria
  1. ICF) 2. Female subjects of non-child bearing potential must be: - Surgically sterile (i.e. bilateral tubal ligation or removal of both ovaries and/or uterus at least 6 months prior to first dosing), or - Naturally postmenopausal (spontaneous cessation of
  2. menses) for at least 24 consecutive months prior to first dosing, with a follicle stimulating hormone level at screening of ≥40 mIU/mL. 3. Body mass index of 18 kg/m2 to 29.9 kg/m2, inclusive, and body weight of 60 kg to 110 kg, inclusive, if male, and 50 kg to 100 kg, inclusive, if female. 4.

  4. 2010) for at least 12 weeks prior to Screening. If the subject was previously diagnosed according to ACR 1987 criteria, the Investigator may classify the subject per ACR 2010 retrospectively, based on medical history, and using available source data 5. Must have received Methotrexate (MTX), sulfasalazine, or hydroxychloroquine for at least 12 weeks prior to Day 1 and in stable dose for at least 6 weeks prior to Day 1 without significant Adverse events (AEs).

No significant side effects based on the Investigator's judgment should be observed during treatment by these agents. The maximum allowed doses of sulfasalazine and hydroxychloroquine are: 1. Sulfasalazine: 3 g per day 2. Hydroxychloroquine: 400 mg per day Note: The doses should remain stable and not be changed from the time of signing the ICF until the end of the treatment period (EOT, Day 29). 6. Subjects must have an increased CRP at Screening (of ≥1.2 × ULN).
