Effect of Roflumilast and Desloratadine as Add-On Therapy in Patients With Rheumatoid Arthritis

8. maj 2026 opdateret af: Amira Fawzy Mohamed Mashaly, Horus University

Clinical Study to Compare the Possible Efficacy and Safety of Roflumilast and Desloratadine as Adjuvant Therapy for Rheumatoid Arthritis

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.

Detaljeret beskrivelse

Rheumatoid arthritis (RA) is a systemic autoimmune disease characterized by chronic synovial inflammation, progressive joint destruction, and impaired quality of life. Despite the availability of conventional disease-modifying antirheumatic drugs (DMARDs), a subset of patients continues to have persistent disease activity and inflammatory burden.

Phosphodiesterase-4 inhibitors and antihistamines have demonstrated potential anti-inflammatory and immunomodulatory effects that may be beneficial in rheumatoid arthritis. Roflumilast, a selective phosphodiesterase-4 inhibitor, reduces the production of pro-inflammatory cytokines, while desloratadine has been shown to exhibit additional anti-inflammatory properties beyond its antihistaminic effect.

This randomized, double-blind, placebo-controlled clinical trial is designed to evaluate the efficacy and safety of roflumilast or desloratadine as add-on therapy to standard DMARD treatment in patients with rheumatoid arthritis. Eligible participants will be randomized into three parallel groups to receive either roflumilast, desloratadine, or placebo for a duration of three months.

Clinical assessments will include evaluation of disease activity scores, inflammatory biomarkers, and patient-reported outcomes. Safety and tolerability will be monitored throughout the study period. The findings of this study may provide evidence for novel adjunctive therapeutic strategies in the management of rheumatoid arthritis.

Hvad måler undersøgelsen?

Primære resultatmål

Resultatmål
Foranstaltningsbeskrivelse
Tidsramme
Change in Disease Activity Score (DAS28)
Tidsramme: Baseline to 12 weeks
Disease activity will be assessed using the Disease Activity Score in 28 joints (DAS28), which is a composite index ranging from 0 to approximately 9.4. Higher DAS28 scores indicate greater disease activity. The primary outcome is the change in DAS28 score from baseline to 12 weeks.
Baseline to 12 weeks

Sekundære resultatmål
