Trial Outcomes & Findings for An Open-Label Extension Study Assessing the Long-Term Efficacy and Safety of ALX-0061 in Subjects With Rheumatoid Arthritis (NCT NCT02518620)

NCT ID: NCT02518620

Last Updated: 2019-07-30

Results Overview

ACR 20 response is defined as: * 20% improvement in tender joint count (TJC; 68 joints) relative to Week 0 AND * 20% improvement in swollen joint count (SJC; 66 joints) relative to Week 0 AND * 20% improvement in 3 of the following 5 areas relative to Week 0: * Subject's Assessment of Pain (100 mm - visual analogue scale \[VAS\]) * Subject's Global Assessment of Disease Activity (VASPA) * Physician's Global Assessment of Disease Activity (VASPHA) * Subject's assessment of physical function as measured by Health Assessment Questionnaire-Disability Index (HAQ-DI) * C-reactive protein (CRP) level ACR20 responses were measured at Weeks 0, 12, 24, 36, 48, 60, 72, 84, 96, and 104 and Weeks 0, 12, 48, and 104 reported.

Participant Flow

A total of 406 subjects was enrolled at 56 sites located in Europe (48 sites, 333 subjects) and Latin America (8 sites, 73 subjects). Consent was obtained from the first subject on 13 July 2015; the last subject completed the final visit on 23 August 2018.

A total of 472 subjects completed the entire treatment and assessment period of the preceding Phase IIb studies (placebo and ALX-0061 treatment arms only). Of these, 406 subjects were enrolled in this study. All screened subjects were included in the Intent-to-observe (ITO) Population. Overall, 405 subjects were included in the Safety Population.
