Number of Participants With Treatment-emergent Adverse Events Primary · From first dose of study drug up to end of study (week 19).

An adverse event (AE) is any untoward medical occurrence in a participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment, including any such occurrence (eg, sign, symptom, or diagnosis) or worsening of a pre-existing medical condition. A serious adverse event was defined as an adverse event that was fatal; was life threatening; required in-patient hospitalization or prolongation of existing hospitalization; resulted in persistent or significant disability/incapacity; was a congenital anomaly/birth defect; or other significant

The investigator reviewed laboratory test results and determined whether an abnormal value in an individual study participant represented a change from prestudy values and determined if changes were clinically significant. The number of participants with clinically significant changes in lab values at any time during the study is reported.

Samples were tested in a validated immunoassay for the presence of anti-brodalumab binding antibodies. Samples found to be positive for binding antibodies were further tested using a validated cell-based bioassay to determine if the antibodies were able to neutralize the activity of brodalumab.

Sponsor's own description

This Phase 1b/2a study will evaluate safety, tolerability pharmacokinetics (PK) and pharmacodynamics (PD) of brodalumab when administered in multiple subcutaneous (SC) and intravenous (IV) doses in patients with active rheumatoid arthritis (RA) in combination with a stable dose of disease modulating anti-rheumatic drugs (DMARDs). Part A is dose escalation (to assess safety \& tolerability), and Part B is dose expansion (to assess clinical efficacy) at the highest tolerated dose level of brodalumab from Part A.
