If currently not using LEF, must not have received for at least 12 weeks before first administration of study agent. a. If using MTX, the route of administration and dose must be stable and the dose must be ≤25 mg/week. b. If receiving SSZ, the dose must be ≤ 3g/day. c. If receiving HCQ, the dose must be ≤400 mg/day. d. If receiving LEF, the dose must be ≤20 mg/day. 8.
