Timeline
Interventions
A loading dose of 100 mg (or placebo) for three (3) days will be given. Following that three-day period, a dose of 20 mg/day will be maintained throughout the remainder of the study. This dose may be decreased to 10 mg/day at the discretion of the treating physician if minor toxicities occur (e.g., diarrhea, liver enzyme elevations
Methotrexate: dosing starts at 10mg/week (4 tabs/wk). If total remission (according to ACR criteria found in Appendix II) has not been achieved and the labs are acceptable at the 8-week evaluation, the dose increased to 15 mg/week (6 tabs/wk);at the 16-week evaluation, the dose increased to 20 mg/week (8 tabs/wk). This dose will remain stable until the end of the study. Sulfasalazine: dosing will start at 500 mg bid (1000 mg/day). This dose will remain steady until the 24-week evaluation. If total remission has not been achieved by this time and the labs remain acceptable,dose will be increased to 1000 mg bid (2000 mg/day) Hydroxychloroquine: dosing will be started and maintained throughout the study at 200 mg bid (400 mg/day).
Leflunomide: dose of 100 mg (or placebo) for three (3) days. Followed by a dose of 20 mg/day will be maintained throughout the remainder of the study. dose may be decreased to 10 mg/day at the discretion of the treating physician if minor toxicities occur Sulfasalazine: dosing will start at 500 mg bid (1000 mg/day). This dose will remain steady until the 24-week evaluation. If total remission has not been achieved by this time and the labs remain acceptable, dose will be increased to 1000 mg bid (2000 mg/day) Hydroxychloroquine: dosing will be started and maintained throughout the study at 200 mg bid (400 mg/day).
