This post hoc analysis evaluated tildrakizumab efficacy, durability of response, and safety in patients with moderate to severe chronic psoriasis with vs without metabolic syndrome (MetS) using pooled data from 2 phase 3, double-blind, randomized, placebo-controlled studies (reSURFACE 1 [NCT01722331] and 2 [NCT01729754]). Patients with vs without MetS had higher prevalence of pre-existing cardiovascular disease and diabetes and higher median baseline weight and body mass index (BMI). Six (4.1%) patients with MetS (n=5 tildrakizumab 100 mg; n=1 tildrakizumab 200 mg) and 25 (4.5%) patients without MetS (n=12 tildrakizumab 100 mg; n=13 tildrakizumab 200 mg) did not complete the study. Percentages of patients with ≥75% improvement on the Psorasis Area and Severity Index (PASI 75 responders) at weeks 12 and 52 were comparable between patients with and without MetS for both tildrakizumab doses. Percentages of PASI 90 and PASI 100 responders through week 52 were similar regardless of MetS status for both tildrakizumab doses. Tildrakizumab efficacy through week 52 was maintained comparably in patients with and without MetS. Reductions in mean PASI from baseline were similar regardless of MetS status for both tildrakizumab doses. Percentages of patients with ≥1 serious adverse event (AE) and those with ≥1 serious infection were similar in patients with and without MetS. The most common serious AEs for patients with vs without MetS were gastrointestinal and cardiac disorders following tildrakizumab 100 mg and injury / procedural complications and nervous system disorders following tildrakizumab 200 mg. Fatal AEs occurred in 2 patients with MetS (both tildrakizumab 100 mg) and 2 patients without MetS (1 per tildrakizumab dose). Infection was the most commonly reported treatment-emergent AE (TEAE). Incidence was similar in patients with and without MetS receiving tildrakizumab 100 mg and numerically higher in patients with vs without MetS receiving tildrakizumab 200 mg. Incidence of cardiovascular events did not vary by MetS status, and there were no reports of diabetes worsening after treatment. Weight increases through week 28 were limited (~1 kg on average) in patients with and without MetS across both tildrakizumab doses. Exposure-adjusted rates of tier 1 TEAEs were comparable across doses regardless of MetS status. These post hoc analyses were not powered for statistical analyses based on MetS status, and populations were not matched for smoking history and other potential co-factors. Although abdominal obesity is more highly correlated with MetS risk factors relative to BMI, the latter was used as abdominal obesity data were not collected. Sample sizes for patients with MetS were relatively small; further evaluation of the effect of weight only on treatment efficacy and safety was not feasible because only 25 patients with BMI <30 kg/m2 met ≥3 criteria for MetS. Despite limitations, these results suggest efficacy, safety, and drug survival of tildrakizumab are comparable in patients with psoriasis regardless of MetS status.
