Effects of Intravenous Golimumab on Health-Related Quality of Life in Patients With Psoriatic Arthritis: 24-Week Results of the GO-VIBRANT Trial.

OBJECTIVES

Evaluate the effects of intravenous golimumab 2 mg/kg on multiple domains of health-related quality of life (HRQoL) in adult patients with active psoriatic arthritis (PsA).

METHODS

In this phase III, randomized, double-blinded, placebo-controlled study, adults with active PsA were randomized in a 1:1 ratio to receive intravenous (IV) infusions of placebo (n = 239) or golimumab 2 mg/kg (n = 241) at weeks 0, 4, 12, and 20. Physical function was assessed using the Health Assessment Questionnaire-Disability Index (HAQ-DI). HRQoL was assessed using the 36-item Short-Form Health Survey Physical and Mental Component Summary (SF-36 PCS/MCS) scores, the Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue, EQ VAS, and the Dermatology Life Quality Index (DLQI).

RESULTS

Patients in the golimumab group had greater mean changes from baseline in HAQ-DI compared with placebo at weeks 8 (-0.52 vs -0.10), 14 (-0.60 vs -0.12), and 24 (-0.63 vs -0.14). Mean improvements from baseline in SF-36 PCS (8.0 vs 1.7), SF-36 MCS (5.0 vs 1.2), EQ VAS (17.2 vs 3.7), FACIT-Fatigue (7.9 vs 2.0), and DLQI (-7.2 vs -1.7) were also greater in the golimumab group versus placebo at week 8 and were maintained or increased through week 24. Greater proportions of golimumab-treated patients had improvements greater than or equal to the minimal clinically important difference (MCID) for HAQ-DI, SF-36 PCS/MCS, EQ VAS, FACIT-Fatigue, and DLQI scores at weeks 14 and 24.

CONCLUSION

Improvements in HRQoL were greater in the IV golimumab group compared with placebo and were evident at week 8 and sustained through week 24.
