Conditions

Rheumatoid Arthritis

Brief summary

A clinical study to investigate the safety of mavrilimumab, an antibody being developed for the treatment of moderate to severe rheumatoid arthritis, an inflammatory condition that affects the joints.

Detailed description

Despite the therapeutic improvements with recent biologic agents approved for rheumatoid arthritis (RA), there is still a significant unmet medical need for the treatment of subjects with this chronic disease to achieve a faster, more complete response, and higher rates of remission. This study is an open-label extension study for subjects who have participated in one of the qualifying development program studies with mavrilimumab. Participation in this study will allow these subjects to continue to receive long-term treatment with mavrilimumab. The data from this study will provide an evaluation of the long-term safety of mavrilimumab in adult subjects with RA. In addition, long-term exploratory efficacy outcomes such as joint damage and disability will be evaluated.

Interventions

Participants will receive 100 mg mavrilimumab once in every 2 weeks (Q2W) subcutaneously for up to 3 years

A serious adverse event (SAE) was an AE resulting in any of following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. TEAEs were defined as AEs with onset date after the first dose of mavrilimumab 100 mg.

Number of Participants With Clinically Meaningful Change in Borg Dyspnea Score Considered as an AEFrom Week 0 to Week 132 at specified time pointsBorg dyspnea score was a validated participant reported outcome assessing participant's perceived difficulty in breathing (dyspnea). The score ranges from 0 (nothing at all) to 10 (maximal difficulty). Higher scores indicated greater difficulty in breathing.

Number of Participants With Treatment-Emergent Adverse Events (TEAEs) and Treatment-Emergent Serious Adverse Events (TESAEs)

An adverse event (AE) was any untoward medical occurrence attributed to study drug in a participant who received investigational product. A serious adverse event (SAE) was an AE resulting in any of following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. TEAEs were defined as AEs with onset date after the first dose of mavrilimumab 100 mg.

Time frame: From the start of study drug administration up to 12 weeks after the last dose of study drug (approximately up to 3 years)

Population: The As-treated Population included participants who received at least one dose of mavrilimumab 100 mg Q2W.

Number of Participants With Vital Sign Abnormalities Reported as Treatment-Emergent Adverse Events (TEAEs)

Vital sign assessments included blood pressure, pulse rate, temperature, weight and respiration rate. Vital sign abnormalities recorded as TEAEs were reported. TEAEs were defined as AEs with onset date after the first dose of mavrilimumab 100 mg.

Time frame: From the start of study drug administration in the study up to 12 weeks after the last dose of study drug (approximately up to 3 years)

Population: The As-treated Population included participants who received at least one dose of mavrilimumab 100 mg Q2W.

Oxygen Saturation Levels by Pulse Oximetry

Oxygen saturation measured by pulse oximetry which measures the concentration of oxygen in the blood.

Time frame: From Week 0 to Week 132 at specified time points

Population: The As-treated Population included participants who received at least one dose of mavrilimumab 100 mg Q2W. Here 'n' represents those participants who were evaluable for this measure at given time points.
