Effect of Roflumilast and Desloratadine as Add-On Therapy in Patients With Rheumatoid Arthritis
Clinical Study to Compare the Possible Efficacy and Safety of Roflumilast and Desloratadine as Adjuvant Therapy for Rheumatoid Arthritis
Source: ClinicalTrials.gov · Last updated 12 May 2026
Brief summary (registry, in English)
Rheumatoid arthritis is a chronic inflammatory disease that causes joint pain, swelling, and disability. Although standard disease-modifying antirheumatic drugs (DMARDs) are effective for many patients, some individuals continue to experience active disease and inflammation. The aim of this study is to evaluate the effectiveness and safety of adding either roflumilast or desloratadine to standard DMARD therapy in patients with rheumatoid arthritis. Participants will be randomly assigned to receive either roflumilast, desloratadine, or placebo in addition to their usual treatment. The study will assess changes in disease activity, inflammatory biomarkers, and patient-reported outcomes over a three-month follow-up period. The results of this study may help identify new add-on treatment options to improve disease control in patients with rheumatoid arthritis.
