To evaluate the long-term efficacy and safety of tildrakizumab treatment for patients with moderate-to-severe psoriasis for up to 148 weeks. Pooled analysis from two double-blind, randomized controlled trials: re 1 and re 2. Efficacy was assessed for responders (≥ 75% improvement in Psoriasis Area and Severity Index; 75) and partial responders ( 50-75) to tildrakizumab 100 mg and 200 mg at week 28 who were maintained on the same dose (administered every 12 weeks), and for partial responders or nonresponders ( < 50) to etanercept 50 mg at week 28 who, after a 4-week washout, were switched to tildrakizumab 200 mg (administered at weeks 32 and 36, and every 12 weeks thereafter). Safety was assessed in the all-patients-as-treated population. Three different methods of imputing missing data were used: nonresponder imputation (), multiple imputation and observed cases. The Clinicaltrials.gov numbers are 01722331 (re 1) and 01729754 (re 2). At week 148 (), 72·6%, 53·8% and 28·9% of tildrakizumab 100-mg responders and 80·2%, 59·9% and 32·6% of tildrakizumab 200-mg responders had 75, 90 and 100 responses, respectively. For partial responders to tildrakizumab 100 mg and 200 mg, the proportions of patients achieving 75, 90 and 100 responses were 32·5%, 25·0% and 10·0%; and 47·1%, 27·5% and 12·8%, respectively. For patients who were partial responders or nonresponders to etanercept, the proportions of patients achieving 75, 90 and 100 responses were 66·9%, 43·8% and 14·9% at week 148. Rates of discontinuations due to adverse events [tildrakizumab 100 mg: 1·7 per 100 patient-years (s); tildrakizumab 200 mg: 1·2 per 100 s] and exposure-adjusted rates of serious adverse events (5·9 per 100 s; 5·5 per 100 s), severe infections (1·1 per 100 s; 1·1 per 100 s), malignancies (0·6 per 100 s; 0·4 per 100 s) and major adverse cardiovascular events (0·4 per 100 s; 0·5 per 100 s) were low. Tildrakizumab was well tolerated and efficacy was well maintained in week 28 responders who continued tildrakizumab treatment through 3 years, or improved among etanercept partial responders or nonresponders who switched to tildrakizumab.
