In a 76-week, randomized controlled trial, patients received 100 mg LJP 394 or placebo weekly for 16 weeks followed by three 12-week treatment cycles of 50 mg LJP 394 or placebo weekly each separated by eight-week periods when no therapy was administered. Health-related quality of life (HRQOL) was assessed using SF-36 at baseline, 16 weeks and every 12 weeks thereafter. Analyses populations included intent to treat (ITT) (n = 179) and patients with high-affinity anti-dsDNA antibody binding (HA): 157/179; 85% active, 90% placebo. In the ITT population, there were improvements in role emotional (RE) (+7.3 versus -8.2), social functioning (SF) (+4.3 versus +0.7), and role physical (RP) (+11.3 versus +6.0) domains in the active treatment group when compared with placebo, with similar changes observed in the HA population. In 37 patients with data pre- and post-renal flares, those receiving LJP 394 reported stabilization or improvement in all but one domain compared with deterioration in all domains with placebo. Changes in RE domain scores following a flare differed by 22.7 points between the two treatment groups, favouring LJP 394 treatment.

Patients receiving LJP 394 reported stable or improved HRQOL with active treatment following renal flares compared with deterioration in placebo. Differences between treatment groups in RE and SF domains are clinically important and were replicated irrespective of the protocol population analysed.
