Spondyloarthritis & psoriatic arthritis
Guselkumab provides sustained domain-specific and comprehensive efficacy using composite indices in patients with active psoriatic arthritis
Authors' conclusion
Treatment with guselkumab provided robust and sustained benefits across multiple PsA domains through 1 year, indicating that guselkumab is an effective therapy for the diverse manifestations of PsA.
Study context
- Population
- Patients with active PsADISCOVER-1 n = 381
- Comparison
- Guselkumab 100 mg Q4W or Q8W vs placebo
- Outcome
- Efficacy by composite indices:
- DAPSA
- Psoriatic Arthritis Disease Activity Score (PASDAS)
- Minimal disease activity (MDA)
- Very low disease activity (VLDA)
- Follow-up
- Through week 52
Methodological detailsplacebo-controlled, placebo crossover to guselkumab at week 24, non-responder imputation through week 52
- Placebo-controlled
- Placebo crossover to guselkumab at week 24
- Non-responder imputation through week 52
Pooled result
As reported in the abstract
DAPSA low disease activity (LDA) and remission, PASDAS LDA and VLDA, MDA, and VLDA · week 24
Greater proportions of guselkumab- than placebo-treated patients achieved each index
all unadjusted P < 0.05
