Immune checkpoint inhibitors in patients with pre-existing psoriasis: safety and efficacy

Abstract: BackgroundImmune checkpoint inhibitors (ICIs) are approved to treat multiple cancers. Retrospective analyses demonstrate acceptable safety of ICIs in most patients with autoimmune disease, although disease exacerbation may occur. Psoriasis vulgaris is a common, immune-mediated disease, and outcomes of ICI treatment in patients with psoriasis are not well described. Thus we sought to define the safety profile and effectiveness of ICIs in patients with pre-existing psoriasis.MethodsIn this retrospective cohort s… Show more

“…Patients with pre-existing autoimmune disorders are largely excluded from clinical trials, and their long-term outcomes are not well described. Data from a number of studies suggest that these patients have similar or slightly higher rates of classic irAEs, and similar antitumour responses compared with those of individuals without autoimmune disease, although these patients also have high incidences of autoimmune flares (20–25%) 142 145 . In our anecdotal experience, any autoimmune disease flares will usually improve following treatment discontinuation, although the long-term outcomes in these patients need to be studied in more detail.…”

“…High grade psoriasiform DAEs to anti-CTLA-4 and anti-PD-1/PD-L1 blockade have been widely reported in the literature ( 53 56 ). In FAERS, 152 cases of psoriasiform DAEs have been recorded in association with pembrolizumab, 40 with ipilimumab, 243 with nivolumab, 57 with atezolizumab, 5 with avelumab, 24 with durvalumab, and 4 with cemiplimab.…”

“…Seven patients experienced grade 3–4 psoriasiform DAEs and 16 (21%) required systemic therapy. Of the 15 patients with pre-existing psoriatic arthritis prior to ICB, 6 experienced arthritis flares ( 56 ). Notably, progression-free survival was significantly longer in patients who experienced a psoriasis flare compared to those who did not (39 vs. 8.7 months, p = 0.049) ( 56 ).…”

“…Ein Absetzen der ICI-Therapie war in 7 % erforderlich. Die Dauer bis zur Tumorprogression war bei Patienten mit Zunahme der Psoriasisaktivität fast 5-fach länger [25]. In einer anderen Serie wurde eine Aktivitätszunahme vorbestehender Autoimmunerkrankungen in 28 % sowie das Auftreten zusätzlicher Autoimmunerkrankungen in 21 % beobachtet.…”
