Early Phase Study to Assess Efficacy and Safety of AZD9567 Versus Prednisolone in Patients With Rheumatoid Arthritis

Rheumatoid Arthritis Clinical Trial

Official title: A Phase 2a, Randomised, Double-blind, Parallel Study to Assess the Efficacy, Safety and Tolerability of AZD9567 Compared to Prednisolone 20 mg in Patients With Active Rheumatoid Arthritis (RA)

Status Completed

Clinical Trial Summary

This is a phase 2a study to be run in 2-3 countries in European Union involving 5-6 sites. It will enroll approximately 80 patients to ensure 40 randomized with active rheumatoid arthritis. The treatment period is 2 weeks and total study duration per patient is approximately 1 month. The study drugs are AZD9567 40 mg (an oral SGRM) and the comparator is prednisolone 20mg. The primary endpoint is DAS28 including evaluation of 28 joints and C-reactive protein. Safety parameters will also be evaluated and a biomarker program is included for future research.

Clinical Trial Description

This randomized double blind with double dummy technique phase 2a study will be run in 2-3 EU countries, most likely Sweden, Denmark and The Netherlands involving 5-6 sites. It is estimated that 80-100 patients have to be enrolled to ensure the randomization target of 40. The study population is patients with rheumatoid arthritis on stable treatment with conventional disease-modifying anti-rheumatic drugs (DMARDs) with an active flare. It is a two-arm parallel study and the randomization ratio is 1:1 to the two weeks of once daily treatment of 40 mg of AZD9567 and 20 mg prednisolone.

The primary objective is to assess the efficacy of AZD9567 40 mg, compared to prednisolone 20 mg in patients with active rheumatoid arthritis in spite of stable treatment with conventional and/or s.c/i.v. biological DMARDs and the primary variable is change from baseline in 28 joint Disease Activity Score using CRP (DAS28 - CRP). As secondary variables swollen and tenderness of 66-68 joints and safety variables are also included. For exploratively purposes there is also a biomarker program, collecting blood samples for future research. ;
