  • Il presente studio riporta una revisione globale relativa alla sicurezza di ixekizumab nei pazienti adulti con psoriasi moderata-severa fino a 5 anni di utilizzo.
  • Il profilo di sicurezza a lungo termine di ixekizumab è in linea con quanto riportato in precedenza e non sono stati riportati eventi avversi inaspettati.


We report a comprehensive summary of the safety outcomes in adult patients with moderate-to-severe psoriasis with up to 5 years of exposure to ixekizumab.

Long-term safety of the IL-17A antagonist ixekizumab was assessed from 17 randomized trials. Treatment-emergent adverse events (TEAEs)-adjusted incidence rates (IRs) per 100 patient-years (PY) within 1-year time periods through 19 March 2021 were calculated for all patients treated with at least one dose of ixekizumab. Reported cases of major adverse cerebro-cardiovascular events (MACE) and inflammatory bowel disease (IBD) were adjudicated.

A total of 6892 adult patients with a cumulative exposure of 18,025.7 PY were included. The IRs per 100 PY for any TEAE and serious adverse events (AEs) were 32.5 and 5.4. IR of discontinuation because of AE was 2.9. A total of 36 deaths were reported. IR of serious infections was low (1.3). There were no confirmed cases of reactivation of tuberculosis (TB). IR of Candida infections (IR 1.9) was low; most cases of Candida were localized, and no systemic cases were reported. IRs of injection site reactions and allergic/hypersensitivity were 5.9 and 5.6, respectively. No confirmed cases of anaphylaxis were observed. IRs were low for malignancies, depression, cytopenia, and MACE (all ≤1.2). IBD events were uncommon, although a total of 31 patients (IR 0.2) had confirmed IBD (ulcerative colitis, n = 18; Crohn disease, n = 13). Across safety topics, IRs decreased or remained constant over time.

The long-term safety profile for ixekizumab is consistent with that previously reported in patients with psoriasis. No new or unexpected safety events were detected.
