Network meta-analysis comparing the efficacy of biologic treatments for achieving complete resolution of nail psoriasis

Background Nail psoriasis (NP) is common and of high importance in patients with psoriasis. Complete resolution of NP at week 24-26 is an unambiguous nail outcome accessible for indirect treatment comparison of biologics. Objective To evaluate the comparative efficacy of approved biologics in achieving complete resolution of NP at week 24-26. Methods A network meta-analysis (NMA) was conducted to indirectly compare the efficacy of six biologics in achieving complete resolution of NP at week 24-26 in patients with moderate-to-severe psoriasis and concomitant NP. Complete resolution of NP was defined as a score of zero on the Nail Psoriasis Severity Index (NAPSI), modified NAPSI (mNAPSI) or Physician's Global Assessment of Fingernails (PGA-F). Results The probability of achieving complete resolution of NP was highest for ixekizumab (46.5%; 95% credibility interval [CrI] 35.1-58.0; Surface Under the Cumulative RAnking curve [SUCRA] 97%), followed by brodalumab (37.0%; 17.0-61.0; 79%), adalimumab (28.3%; 24.4-32.4; 62%), guselkumab (27.7%; 21.1-35.1; 58%), ustekinumab (20.8%; 10.2-35.2; 37%), and infliximab (0.8%; 0.0-8.9; 17%). Conclusion In patients with moderate-to-severe psoriasis and concomitant NP, ixekizumab has the greatest likelihood among approved biologics of achieving complete resolution of NP at week 24-26. Findings should be interpreted carefully because of inherent study limitations.
