BACKGROUND: The oral administration of drug ß-D-mannuronic acid (M2000) showed a potent therapeutic effect in phase I/II study in rheumatoid arthritis (RA) patients. Here, our aim is to assess the efficacy and safety of this new drug in RA patients under a multinational, randomized placebo-controlled phase III clinical trial. METHOD: Patients (n = 288) with active disease at baseline and inadequate response to conventional drugs were randomly allocated to three groups; (1) receiving mannuronic acid at a dose of two capsules (500 mg) per day orally for 12 weeks, (2) placebo-controlled, and (3) conventional. The primary endpoints were the America College of Rheumatology 20 response (ACR20), 28-joint disease activity score (DAS28) and Modified Health Assessment Questionnaire-Disability Index (M-HAQ-DI). In addition, the participants were followed-up for safety assessment. RESULTS: In this phase III trial, after 12 weeks of treatment, there was a significant reduction in ACR20 between mannuronic-treated patients compared to placebo and conventional groups. Moreover, there was a similar significant improvement for DAS28 following mannuronic therapy. The statistical analysis showed a significant reduction in the swollen and tender joint count in mannuronic-treated patients compared with the placebo group. On the other side, mannuronic acid showed no-to-very low adverse events in comparison to placebo. CONCLUSION: The results of this multinational, phase III clinical trial provided a potent evidence base for the use of ß-D-mannuronic acid as a new highly safe and efficient drug in the treatment of RA.
