Brief Summary

This is a fifteen-month open label, Phase IIa clinical trial is being conducted to assess the tolerability, safety and efficacy of a medication called Tocilizumab (Actemra®) in patients with polymyalgia rheumatica (PMR).

Detailed Description

This fifteen-month open label, Phase IIa clinical trial is being conducted to assess the tolerability, safety and efficacy of a medication called Tocilizumab (Actemra®) in patients with polymyalgia rheumatica (PMR). The typical symptoms of PMR are muscle pain and stiffness in the shoulder, neck or hip region. Steroids have traditionally been used to treat this condition with great success, although long courses of steroids, up to 2 years in many cases, are often required. This can result in many unwanted side effects including diabetes, high blood pressure, heart disease, cataracts, weak bones with fractures, weak muscles, skin bruising, difficulty sleeping and mood disturbances. In this trial, the steroid dosage will be decreased much more quickly than what is done in routine clinical practice; there is an expectation that steroid therapy will be withdrawn within six months.

Tocilizumab is a medication already on the market that has been FDA approved in the US and Japan for the treatment of rheumatoid arthritis, and in Japan it is also approved for certain types of juvenile idiopathic arthritis (which is like rheumatoid arthritis in children) and Castleman's disease (which is a rare disease that causes enlarged lymph nodes). It is not FDA approved to treat polymyalgia rheumatica at this time. In this study, it will be given as an intravenous infusion once a month for a treatment period of one year. Experiments done on the blood of patients with PMR show one particular cytokine or small molecule that circulates throughout the body, interleukin-6, to be elevated in this disease. Tocilizumab is a medication that is designed to specifically block this cytokine. The co-primary endpoints for this study include efficacy, as well as evaluations of safety and tolerability.

• Efficacy will be defined by the proportion of patients in Disease Remission (DR) off corticosteroids, without relapse or recurrence, at six months from trial entry
• Safety and tolerability of Tocilizumab will be evaluated during the fifteen-month study period by the monitoring of adverse events and immunogenicity surveillance

Disease Remission (DR) will be defined as the disappearance of signs and symptoms of polymyalgia rheumatica (aching and stiffness of the shoulder, hip girdle, or both) with normalization of erythrocyte sedimentation rate (ESR<30 mm/hr) and c-reactive protein (CRP ≤1.0 mg/dl), unless elevation of ESR and/or CRP are attributable to causes other than PMR (i.e., infection).

Conditions

Polymyalgia Rheumatica (PMR)

Study Design

• Allocation Method: NA
• Intervention Model: SINGLE_GROUP
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

Tocilizumab

This is a single-arm study. All subjects will receive the active study treatment for 12 months, and will then be evaluated for 3 months of long-term follow-up.

Group Type: EXPERIMENTAL

Tocilizumab

Intervention Type: DRUG

Tocilizumab is a humanized anti-interleukin-6 receptor antibody that has been FDA approved for the treatment of rheumatoid arthritis (RA). This molecule binds to the IL-6 binding site of human IL-6 receptor, and competitively inhibits IL-6 signaling.
