Phase 2
Completed
Conditions
Rheumatoid Arthritis
Psoriatic Arthritis
Ankylosing Spondylitis
Non-Radiographical Axial Spondyloarthritis
Interventions
Drug: Placebo
Drug: Standard of Care
Registration Number
NCT03926195
Lead Sponsor
Galapagos NV
Brief Summary

The primary objective of this study is to evaluate the effect of filgotinib on semen parameters in adult males with active rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, or non-radiographic axial spondyloarthritis.

Results of this study may be pooled with the results of a separate study being conducted in participants with inflammatory bowel disease (Protocol GS-US-418-4279; NCT03201445) with the same objective.

FilgotinibFilgotinibParticipants received filgotinib 200 milligrams (mg) tablet, orally, once daily up to Week 13 in the double-blind (DB) phase. At Week 13, participants who were arthritis responders, were unblinded and received open-label (OL) treatment filgotinib 200 mg, tablet, orally, once daily up to approximately 143 weeks (until Week 156) in the extension (EXT) phase and participants who were arthritis nonresponders discontinued blinded study drug and started standard of care (SOC) treatment in the EXT phase. Participants on DB treatment or OL filgotinib who entered the monitoring phase (if their sperm parameters met ≥50% decrease threshold in pre-specified semen parameters) discontinued the study drug and started SOC for up to 52 weeks.

PlaceboPlaceboParticipants received placebo (matched to filgotinib) tablet, orally, once daily up to Week 13 in the DB phase. At Week 13, participants were unblinded and started SOC treatment in the EXT phase for up to approximately 143 weeks (until Week 156). Participants who entered the monitoring phase (if their sperm parameters met ≥50% decrease threshold in pre-specified semen parameters) continued on SOC treatment.

Primary Outcome Measures
NameTimeMethod
Percentage of Participants With a ≥ 50% Decrease From Baseline in Sperm Concentration at Week 13Baseline to Week 13

Baseline for sperm/semen parameters was the mean of 2 evaluable semen samples at screening. The normal range for sperm concentration is ≥15 million sperms/mL.

Percentage change = (\[mean at Week 13 - baseline\] / baseline) × 100; value at Week 13 was the mean of 2 evaluable samples collected at Week 13.

Secondary Outcome Measures
NameTimeMethod
Change From Baseline in Sperm Total Motility at Week 13Baseline, Week 13

The normal range for sperm total motility is ≥40%.

Percentage of Participants With a ≥ 50% Decrease From Baseline in Sperm Concentration at Week 26Baseline to Week 26

Arthritis responder: For rheumatoid arthritis (RA), psoriatic arthritis (PsA), ankylosing spondylitis (AS), and non-radiographic axial spondyloarthritis (nrAxSpA), a participant with an improvement in the Physician's Global Assessment of Disease Activity (PhGADA) of at least 20% compared with baseline (Day 1) at the specified assessment time.

Arthritis nonresponder: For RA, PsA, AS, or nrAxSpA, a participant who did not fulfill the definition of arthritis responder at the specified assessment timepoint.

PhGADA: Physician measured the participant's disease severity on a visual analogue scale (VAS) ranged from 0 (no disease)-100 (worst disease) millimeters (mm).

Baseline value for sperm/semen parameters was the mean of 2 evaluable semen collections at the screening visit. The normal range for sperm concentration is ≥15 million sperms/mL.

Percentage change = (\[mean at Week 26 - baseline\] / baseline) × 100; value at Week 26 was the mean of 2 evaluable samples collected at Week 26.
