What this trial studies

This interventional study aims to assess the efficacy and safety of nicotinamide supplementation in patients with rheumatoid arthritis who are already receiving conventional synthetic disease-modifying anti-rheumatic drugs. Participants will be randomly assigned to either a nicotinamide group, receiving a daily dose of 1000mg, or a control group, continuing their standard therapy. The study will evaluate clinical outcomes and disease activity through various assessments, including blood tests and disease activity scores, over a three-month period.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-65 with established rheumatoid arthritis and moderate to high disease activity.

Not a fit: Patients with hypersensitivity to nicotinamide, those on biologic therapies, or with significant liver or kidney impairment may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new adjunctive treatment option to improve the quality of life for patients with rheumatoid arthritis.

How similar studies have performed: While the use of nicotinamide in this context is relatively novel, previous studies have explored its benefits in other conditions, suggesting potential for success.
