University of Nebraska91 enrolled

Overview

The purpose of this study is to determine if a combination of methotrexate and minocycline works better than methotrexate alone in early Rheumatoid Arthritis

The purpose of this study is to determine if a combination of methotrexate and minocycline works better than methotrexate alone in early Rheumatoid Arthritis (RA). Specific aims of this study are: A. To demonstrate that the combination of minocycline and methotrexate is well tolerated when used in the first year of RA. B. To compare the efficacy of the combination of minocycline and methotrexate with methotrexate and placebo therapy in early sero-positive RA patients.

Combination of Minocycline and MTX or MTX aloneDRUG

Methotrexate Dosing: 1)initial dose of methotrexate for all patients will be 10 mg/week. 2)2 month: dose of MTX will remain at 10 mg/week if full remission criteria are met; otherwise, increased to 15 mg/week. 3)4 month: dose of MTX will remain at its current level if full remission criteria are met; otherwise, be increased to 20 mg/week. 4)6, 8 and 10 month: If the patient has fallen below full remission criteria and is not already receiving the maximum dose of 20 mg/week,dose will be increased to 20 mg/week. If the patient meets ACR 50 criteria prednisone will be tapered by 1mg/month 5)12 month evaluation: End of the blinded portion of the study. minocycline dosage 200 mg

Time frame: 48 weeks

Secondary Outcomes

Comparison of combination therapy versus methotrexate alone, Composite Index
