Brief Summary:

Seropositive Rheumatoid arthritis (RA) is characterized by autoantibodies that develop prior to clinical onset, allowing identification of individuals at risk for disease development. In a unique program in Stockholm, seropositive individuals presenting with musculoskeletal complains are currently identified and followed-up in a dedicated outpatient clinical program. Despite significant disease burden and increased sick leave among these individuals, we lack today any therapeutic and preventive measures.

We aim to (1). establish a nation-wide health program, (2). develop an algorithm for disease risk estimation and (3). test a novel strategy to delay and/or prevent disease onset in seropositive at risk individuals with musculoskeletal complains. We will perform a multicentre randomised study to treat autoantibody-positive individuals at risk for developing RA presenting with pain (Population), by repurposing of bisphosphonates (Intervention) as compared to placebo (Control) to treat pain (primary Outcome) and delay/prevent RA development during 1-year follow-up (secondary Outcome)

Seropositive Muskuloskeletal Complaints Drug: Zoledronic Acid Drug: Placebo Phase 4

Detailed Description:

we have recently identified a novel disease-triggering pathogenic mechanism in autoantibody-positive individuals consisting in a bone-mediated induction of pain by autoantibodies. We hypothesize that specific targeting of this new mechanism, rather than using therapies developed for already established disease (where other mechanisms are active), will be able to treat pain with arthralgia and halt disease progression in seropositive at-risk individuals.

We will address this hypothesis by repurposing of bisphosphonates, currently used in clinical practice in both RA patients as well as in many individuals at risk for RA (mainly women in post-menopausal age). We will perform a multi centre, prospective, randomised, double-blind and placebo-controlled study with 2 parallel groups.

Patients will be randomised 1:1 to receive either one infusion aclasta (5 mg zolendronic acid, n=40) or placebo (n=40). The primary outcome is the VAS pain score and the study is powered to detect a 20% difference in the primary endpoint between the active and the control arm. The study is powered to detect a 20-percentage point difference in proportions between the control and the treated group. Subjects may withdraw from the trial at any time at their own or the investigators request for safety reasons.
