Five-year safety of tildrakizumab in patients with moderate-to-severe psoriasis from two phase 3 trials (reSURFACE 1 and reSURFACE 2): number needed to harm for occurrence of adverse events of special interest.

Tildrakizumab demonstrated a favorable safety profile over 5 years with low rates of AESI, comparable to those of the PSOLAR. Consequently, the NNH for AESI with tildrakizumab were very high or negative due to lower event rates for tildrakizumab.
