In this cohort study of patients with treated psoriasis or PsA, we used MarketScan (2014– 2018) to estimate rates of herpes zoster, hepatitis C (HepC) and tuberculosis (TB) with apremilast compared to other systemic treatments.Materials and Methods: Patients were exposed from first apremilast [APR], DMARD, TNF-inhibitor [TNF], IL-inhibitor [IL], or corticosteroids [CS] prescription after March 21, 2014. Study exposures were APR, DMARDs only, TNF-only, IL-only, CS-only, DMARDs+CS, TNF+DMARDs and/or CS, IL+DMARDs and/or CS. Cases had treated herpes zoster, HepC, or TB event. We calculated incidence rates (IRs) [95% confidence intervals] per 1000 patient-years.Results: The study population included 131,604 patients. For herpes zoster (N=2271), IRs were highest for users of DMARDs+CS (12.5 [9.8– 15.7]), CS-only (12.5 [10.4– 14.1]), and TNF+DMARDs and/or CS (11.9 [10.6– 13.4]), compared with DMARDs only (9.9 [8.7– 11.2]). IRs were lowest for users of IL-only (6.7 [5.8– 7.8]) and APR (7.0 [5.8– 8.4]). IRs of HepC (N=150) and TB (N=81) were low and between-treatment differences were not significant.Conclusion: Rates of herpes zoster varied by treatment: highest among those who received polytherapy, lowest in users of apremilast only. IRs for HepC and TB were low for all exposures.Keywords: apremilast, psoriasis, psoriatic arthritis, herpes zoster, hepatitis C, tuberculosis
