Scientific title | Prospective, randomised, double-blind, placebo-controlled clinical trial with hydroxychloroquine (HCQ) in patients with inflammatory osteoarthritis (OA) of the hands |
Study acronym | OA Treat |
Study objectives | Osteoarthritis (OA) is a heterogeneous group of conditions with a disturbed integrity of articular cartilage and changes in the underlying bone. The pathogenesis of OA is multifactorial and involves a complex interplay of genetic, metabolic, biochemical, and biomechanical factors with variable components of inflammation. The disease, as one of the most prevalent musculoskeletal diseases, leads to pain in and around the affected joints and to swelling, stiffness, deformity, and gradual loss of function. It is not just a disease of elderly people, but also affects the younger working age population. Hydroxychloroquine (HCQ) is a disease modifying anti-rheumatic drug (DMARD) that in clinical practice is also used for inflammatory OA and has been employed for the treatment of various rheumatic and dermatologic diseases. Current research has further enhanced our understanding of the pharmacologic mechanisms of action of these drugs involving inhibition of endosomal toll - like receptor (TLR) signalling, which limits B cells and dendritic cell activation. Three studies of HCQ in OA, including one abstract and one letter are available. Most studies show that currently a wide variety of outcome measures are used in rather small patient populations. Despite initial indications for a good effect of HCQ, there has been no randomized, double-blind, and placebo-controlled trial in a larger patient group. In the European League Against Rheumatism (EULAR) evidence based recommendations for the management of hand OA HCQ was not included as a therapeutic option, apparently because of the currently missing randomized clinical trials. The aim of the proposed study is to investigate the efficacy of HCQ by clinical and radiological outcome compared to placebo in patients with severe and refractory inflammatory hand OA. |

Phase | Phase III |
Drug / device / biological / vaccine name(s) | Hydroxychloroquine |
Primary outcome measure | 1. Australian-Canadian OA Index (AUSCAN, German version) for pain, and hand disability as co-primary clinical outcome at week 52 2. Radiographic co-primary endpoint: Radiographic progression assessed by the Kallman Score at week 52 |
Secondary outcome measures | 1. Efficacy of HCQ with respect to AUSCAN at week 26 to patients global assessment of disease activity, patients assessment of stiffness, and physicians global assessment of disease activity at week 26, 52 2. To compare pain, functioning, disability, quality of life, patient-acceptable symptoms and health (HAQ, SF-36, SACRAH, FiHOA, AUSCAN, Backman score, etc.) week 0, 26, 52 3. To assess and to compare the inflammatory status using the following parameters: joint pain and joint swelling, night pain, morning stiffness, local erythema/redness, CRP - and ESR - levels from baseline to week 26, 52 4. To compare cumulative dosage of consumption per week of standard therapy (NSAIDs, COXibs) 5. Assessment of safety: Safety and tolerability of HCQ with reports on adverse event (AE) and serious advere event (SAE) 6. The eye examination will be performed by an ophthalmologist (baseline and every 6 months) |
