Interventions
|
This is a single escalating dose placebo-controlled randomised clinical trial of the efficacy of BiP administered intravenously for the treatment of patients with active rheumatoid arthritis have failed methotrexate therapy.
There are four treatment groups. In each treatment group six patients will be randomly allocated to active treatment and two to placebo. Patients will receive only a single dose. Escalation to the next highest dose will only take place four weeks after safety evaluation from the last visit of the last patient in the previous group. The doses of BiP to be administered are 1, 2.5, 10 or 100 mg per patient. Patients will be monitored closely during the first 24 hours after infusion in a clinical research facility. They will thereafter be reviewed for safety and efficacy at weekly intervals up to four weeks.

|
Primary outcome measure(s)
|
The primary endpoint will be safety. A close watch will be kept on side-effects and in particular serious adverse events. The side-effects will be monitored by a safety committee consisting of two rheumatologists with expertise in this area but who are in no way connected to the trial.
The primary and secondary endpoints will be measured prior to the intravenous infusion, at the end of 24 hours and weekly thereafter to the fourth week.
|
|
Secondary outcome measure(s)
|
1. Clinical efficacy as measured by the Americal College of Rheumatology (ACR) 20, ACR 50 and ACR 70 response criteria and the European League Against Rheumatism Disease Activity Score (EULAR DAS28)
2. Immunological measurements of immune responses such as T-cell proliferation to tuberculin Purified Protein Derivative (PPD), Phytohaemagglutinin (PHA) and BiP; the development of regulatory T-cells; and cytokine production.
The primary and secondary endpoints will be measured prior to the intravenous infusion, at the end of 24 hours and weekly thereafter to the fourth week.
