SUMMARY
- The company cannot recommend any practices, procedures, or usage that deviate from the approved labeling.
- A post-hoc analysis of DISCOVER-2 study assessed the 52-week efficacy and safety outcomes of TREMFYA in adult patients with active psoriatic arthritis (PsA)1
- During a study, a brief description of the use of TREMFYA in a patient with active PsA and comorbid nonalcoholic fatty liver disease (NAFLD) was reported.
CLINICAL DATA
Phase 3 Study
McInnes et al (2021)1 evaluated efficacy and safety results through 52 weeks from the DISCOVER-2, a phase 3, randomized, multicenter, doubleblind, placebo-controlled study analyzing the use of TREMFYA in biologic-naïve adult patients with active PsA.
DISCOVER-2 Study Design2,3

Abbreviations: CASPAR, Classification Criteria for Psoriatic Arthritis; CRP, Creactive protein; DMARD, disease-modifying antirheumatic drug; EE, early escape; NSAID, nonsteroidal anti-inflammatory drug; PsO, psoriasis; R, randomized; SC, subcutaneously; q4w, every 4 weeks; q8w, every 8 weeks.
a238 patients in the placebo group crossed over to guselkumab q4w; 8 patients received placebo only before study drug discontinuation.
bPatients were eligible to initiate/increase background medications if there was <5% improvement from baseline in tender and swollen joint counts at week 16.
- Patients were allowed to receive concomitant stable doses of nonbiologic disease-modifying antirheumatic drugs (DMARDs) (methotrexate ≤25 mg/week, sulfasalazine
≤3 g/day, hydroxychloroquine ≤400 mg/day, or leflunomide ≤20 mg/day), oral glucocorticoids ≤10 mg/day of prednisone or equivalent dose, and nonsteroidal anti-inflammatory drugs (NSAIDs), or other analgesics.1-3 - During the study, a case of grade 1 alanine aminotransferase (ALT) elevation (>1 to 3 times of the upper limit of normal [ULN]) was reported in a patient with a history of NAFLD who switched from placebo to TREMFYA every 4 weeks and discontinued TREMFYA after week 52.1
