          3. Prior receipt of any biologic B-cell-depleting therapy.

          4. Receipt of any anti - tumor necrosis factor alpha (TNF-α) biologic agent < 8 weeks
             prior to screening.

          5. Receipt of any biologic disease-modifying anti-rheumatic drug (bDMARD) with a
             mechanism of action other than direct TNF-α blockade, < 12 weeks or < 5 half-lives of
             the drug prior to screening.

          6. Injectable corticosteroids or treatment with > 10 mg/day dose of oral prednisolone or
