Study Details

This is a Phase 2b, outpatient, randomized, double-blinded (with a single-blind extension), placebo-controlled, dose-ranging, parallel-group study of baricitinib (LY3009104) in Japanese participants with active rheumatoid arthritis (RA) on background methotrexate (MTX) therapy. Baricitinib will be orally administered once a day with background methotrexate \[6 to 16 milligrams (mg)/week\] therapy for 12 weeks in the double-blind treatment period (1, 2, 4 or 8 mg/day, or placebo), and for 52 weeks in the single-blind extension period (4 or 8 mg/day).

Arms

  • Placebo Comparator: Placebo
    2 placebo capsules administered orally once daily for 12 weeks. Participants who complete this treatment arm will be randomized in a 1:1 ratio to either the 4-mg baricitinib or 8-mg baricitinib arms. Participants rerandomized to 8-mg baricitinib arm at Week12 will switch to 4-mg baricitinib once a day after the approval of protocol amendment (d) and will receive that switched dose until Week 64. The dosage form changed from capsule in treatment period (up to Week 12) to tablet in extension period (Week 13 to 64) per protocol amendment (b).
  • Experimental: 1-mg Baricitinib (LY3009104)
    1 x 1-mg baricitinib capsule + 1 identical placebo capsule, both administered orally once daily for 12 weeks. Participants who complete this treatment arm will be randomized in a 1:1 ratio to either the 4-mg baricitinib or 8-mg baricitinib arms. Participants rerandomized to 8-mg baricitinib arm at Week 12 will switch to 4-mg baricitinib once a day after the approval of protocol amendment (d) and will receive that switched dose until Week 64. The dosage form changed from capsule in treatment period (up to Week 12) to tablet in extension period (Week 13 to 64) per protocol amendment (b).
  • Experimental: 2-mg Baricitinib (LY3009104)
    2 x 1-mg baricitinib capsules administered orally once daily for 12 weeks. Participants who complete this treatment arm will be randomized in a 1:1 ratio to either the 4-mg baricitinib or 8-mg baricitinib arms. Participants rerandomized to 8-mg baricitinib arm at Week 12 will switch to 4-mg baricitinib once a day after the approval of protocol amendment (d) and will receive that switched dose until Week 64. The dosage form changed from capsule in treatment period (up to Week 12) to tablet in extension period (Week 13 to 64) per protocol amendment (b).
  • Experimental: 4-mg Baricitinib (LY3009104)
    1 x 4-mg baricitinib capsule + 1 identical placebo capsule, both administered orally once daily for 12 weeks. Participants who complete this 12-week period will remain on this treatment regimen in tablet form.
  • Experimental: 8-mg Baricitinib (LY3009104)
    2 x 4-mg baricitinib capsules administered orally once daily for 12 weeks. Participants who complete this 12-week period will remain on this treatment regimen in tablet form. Participants taking 8-mg baricitinib tablet form will switch to 4-mg baricitinib once a day after the approval of protocol amendment (d) and will receive that switched dose until Week 64.
