Brief summary

* Participants suffering from active rheumatoid arthritis who had an inadequate response to methotrexate were evaluated for improvement of disease activity (efficacy) when taking GLPG0634 as monotherapy (3 different doses - 50 milligram (mg), 100 mg and 200 mg once daily) or matching placebo for 24 weeks. * During the course of the study, patients were also examined for any side effects that could occur (safety and tolerability), and the amount of GLPG0634 present in the blood (Pharmacokinetics) as well as the effects of GLPG0634 on disease- and mechanism of action-related parameters in the blood (Pharmacodynamics) were determined. Also, the effects of different doses of GLPG0634 administration on participants' disability, fatigue and quality of life were evaluated.

Detailed description

* Treatment duration was 24 weeks in total. * However, at Week 12, all participants on placebo and the participants on the 50 mg dose who had not achieved 20% improvement in swollen joint count (SJC66) and tender joint count (TJC68) were assigned (automatically via interactive web response system (IWRS)) to 100 mg once daily (QD) in a blinded fashion and continued treatment until Week 24. * Participants in the other groups maintained their randomized treatment until Week 24.

MeasureTime frameDescription
Percentage of Participants Achieving an American College of Rheumatology (ACR) 20 Response at Week 12Week 12The American College of Rheumatology (ACR) response is a measurement of improvement in multiple disease assessment criteria. The ACR20 response is defined as: 1) ≥ 20% improvement from baseline in SJC66, and 2) ≥ 20% improvement from baseline in tender TJC68, and 3) ≥ 20% improvement from baseline in at least 3 of the following 5 items: 1. Pain visual analog scale (VAS) (taken from the Health Assessment Questionnaire - Disability Index \[HAQ-DI\]), 2. Patient's Global Assessment of Disease Activity VAS, 3. Physician's Global Assessment of Disease Activity VAS, 4. Total HAQ-DI score, and 5. CRP. Non-responder imputation was used (ie, to impute a missing response, the participant was assumed to be a non-responder).

ACR N% Improvement (ACR-N) Response at Weeks 1, 2, 4, 8, 12, and 24Weeks 1, 2, 4, 8, 12, and 24The ACR-N is the smallest percentage improvement in swollen and tender joints and the median of the remaining 5 core parameters, and is expected to be more sensitive to change than the ACR20, ACR50 or ACR70. It is a number varying between 0 and 100, with higher numbers indicating less severity of symptoms. Last observation carried forward (LOCF) algorithm was used (ie, to impute a missing value, the last preceding nonmissing value was used).

Change From Baseline in Simplified Disease Activity Index (SDAI) at Weeks 1, 2, 4, 8, 12, and 24Baseline and Weeks 1, 2, 4, 8, 12, and 24The SDAI is the numerical sum of 5 outcome parameters: TJC28, SJC28, Patient Global Assessment of Disease Activity (in cm), Physician's Global Assessment of Disease Activity (in cm), and CRP (mg/dL). The SDAI was categorized as follows: • High disease activity: SDAI \> 26 • Moderate disease activity: 11 to 26 • Low disease activity: 3.3 to 11 • Remission: ≤ 3.3. LOCF algorithm was used. The SDAI total score ranges from 0 to approximately 86. All placebo participants switched to GLPG0634 treatment at Week 12 and were not included in the analysis of Week 24.
Change From Baseline in Clinical Disease Activity Index (CDAI) at Weeks 1, 2, 4, 8, 12, and 24Baseline and Weeks 1, 2, 4, 8, 12, and 24The CDAI is the SDAI modified to exclude CRP and is the sum of the 4 outcome parameters: TJC28, SJC28, Patient Global Assessment of Disease Activity (in cm), and Physician's Global Assessment of Disease Activity (in cm). The CDAI was be categorized as follows: • High disease activity: \> 22 • Moderate disease activity: 10 to 22 • Mild disease activity: 2.8 to 10 • Remission: ≤ 2.8. LOCF algorithm was used.

The larger the participant's response to the questions (with the exception of 2 negatively stated that are scored reversely), the greater the fatigue. The sum of all responses resulted in the FACIT-Fatigue score for a total possible score of 0 (worse score) to 52 (better score), with a higher score indicating a better quality of life. LOCF algorithm was used. All placebo participants switched to GLPG0634 treatment at Week 12 and were not included in the analysis of Week 24.
Change From Baseline in Quality of Life Using the Short Form-36 (SF-36) Scores at Weeks 4, 12, and 24Baseline and Weeks 4, 12, and 24The SF-36 is a 36-item questionnaire measuring 8 domains (physical functioning, role physical, bodily pain, general health, vitality, social functioning, role emotional, and mental health). Each domain score ranges from 0 (worst) to 100 (best), with higher scores reflecting better health-related functional status. Two summary scale scores were computed based on weighted combinations of the 8 domain scores: the Physical Component Summary (PCS) and the Mental Component Summary (MCS). LOCF algorithm was used. All placebo participants switched to GLPG0634 treatment at Week 12 and were not included in the analysis of Week 24.
Percentage of Participants Achieving ACR/EULAR Remission at Weeks 2, 4, 8, 12, and 24Weeks 4, 8, 12, and 24A participant's disease activity status can be defined as being in remission when scores on the TJC28, SJC28, CRP (actual value in mg/dL) and Patient Global Assessment of Disease Activity (cm) are all ≤ 1. Non-responder imputation was used. All placebo participants switched to GLPG0634 treatment at Week 12 and were not included in the analysis of Week 24.

Change From Baseline in Quality of Life Using the Functional Assessment of Chronic Illness Therapy (FACIT) at Weeks 4, 12, and 24

FACIT-Fatigue scale is a 13-item questionnaire, each scored on a 5-point scale: 0 (Not at all) to 4 (Very much). The larger the participant's response to the questions (with the exception of 2 negatively stated that are scored reversely), the greater the fatigue. The sum of all responses resulted in the FACIT-Fatigue score for a total possible score of 0 (worse score) to 52 (better score), with a higher score indicating a better quality of life. LOCF algorithm was used. All placebo participants switched to GLPG0634 treatment at Week 12 and were not included in the analysis of Week 24.

Time frame: Baseline and Weeks 4, 12, and 24

Population: ITT population with available data were analyzed. Participants who switched treatment at Week 12 were handled as if they discontinued at Week 12. All placebo participants switched to GLPG0634 treatment at Week 12 and were not included in the analysis of Week 24.

Change From Baseline in Quality of Life Using the Short Form-36 (SF-36) Scores at Weeks 4, 12, and 24

The SF-36 is a 36-item questionnaire measuring 8 domains (physical functioning, role physical, bodily pain, general health, vitality, social functioning, role emotional, and mental health). Each domain score ranges from 0 (worst) to 100 (best), with higher scores reflecting better health-related functional status. Two summary scale scores were computed based on weighted combinations of the 8 domain scores: the Physical Component Summary (PCS) and the Mental Component Summary (MCS). LOCF algorithm was used. All placebo participants switched to GLPG0634 treatment at Week 12 and were not included in the analysis of Week 24.

Time frame: Baseline and Weeks 4, 12, and 24

Population: ITT population with available data were analyzed. Participants who switched treatment at Week 12 were handled as if they discontinued at Week 12.

Change From Baseline in Simplified Disease Activity Index (SDAI) at Weeks 1, 2, 4, 8, 12, and 24

The SDAI is the numerical sum of 5 outcome parameters: TJC28, SJC28, Patient Global Assessment of Disease Activity (in cm), Physician's Global Assessment of Disease Activity (in cm), and CRP (mg/dL). The SDAI was categorized as follows: • High disease activity: SDAI \> 26 • Moderate disease activity: 11 to 26 • Low disease activity: 3.3 to 11 • Remission: ≤ 3.3. LOCF algorithm was used. The SDAI total score ranges from 0 to approximately 86. All placebo participants switched to GLPG0634 treatment at Week 12 and were not included in the analysis of Week 24.

Time frame: Baseline and Weeks 1, 2, 4, 8, 12, and 24
