Treatment of Early Rheumatoid Arthritis: Minocycline in Combination With Methotrexate Versus Methotrexate Alone

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

Study Overview

Detailed Description

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.

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
