Summary

The purpose of this study is to evaluate the safety and efficacy of 3 different doses of belimumab, administered in addition to standard therapy, in patients with rheumatoid arthritis (RA).

Detailed description

The purpose of this study is to evaluate the safety and efficacy of three different doses of belimumab (1 mg/kg, 4 mg/kg, and 10 mg/kg), administered in addition to standard therapy, compared to placebo plus standard therapy in patients with RA. All patients were to be dosed on Days 0, 14, and 28, then every 28 days for the remainder of 24 weeks. Patients completing the 24-week period could enter a 24-week open-label extension; belimumab patients received the same dose or were switched to 10 mg/kg at the investigator's discretion and former placebo patients received belimumab 10 mg/kg.

Interventions

Type	Name	Description
DRUG	Placebo	Placebo IV plus standard therapy (SOC) for RA; placebo administered on Days 0, 14, 28, and every 28 days thereafter through 24 weeks in the double-blind period. In the open-label extension period, placebo patients who opted to participate received belimumab 10 mg/kg IV plus SOC every 28 days for an additional 24 weeks.
DRUG	Belimumab 1 mg/kg	Belimumab 1 mg/kg IV plus standard therapy (SOC) for RA; belimumab 1 mg/kg administered on Days 0, 14, 28, and every 28 days thereafter through 24 weeks in the double-blind period. In the open-label extension period, patients who opted to participate either continued on the same dose of belimumab or may have been switched to belimumab 10 mg/kg at the investigator's discretion for an additional 24 weeks.
DRUG	Belimumab 4 mg/kg	Belimumab 4 mg/kg IV plus standard therapy (SOC) for RA; belimumab 4 mg/kg administered on Days 0, 14, 28, and every 28 days thereafter through 24 weeks in the double-blind period. In the open-label extension period, patients who opted to participate either continued on the same dose of belimumab or may have been switched to belimumab 10 mg/kg at the investigator's discretion for an additional 24 weeks.
DRUG	Belimumab 10 mg/kg	Belimumab 10 mg/kg IV plus standard therapy (SOC) for RA; belimumab 10 mg/kg administered on Days 0, 14, 28, and every 28 days thereafter through 24 weeks in the double-blind period. In the open-label extension period, patients who opted to participate continued on the same dose of belimumab (10 mg/kg) for an additional 24 weeks.
