Abstract

Dose reduction of biologics for psoriasis could contribute to lower drug exposure. This study evaluated a one-step, tightly controlled, biologic dose reduction strategy in a prospective daily practice cohort. In patients with psoriasis with low disease activity using adalimumab, etanercept or ustekinumab for at least 6 months, the dosing interval was prolonged with 33%. Patients could return to their normal dosing interval in case of disease flare. Of 108 eligible patients, 80 started dose reduction and were analysed. In total, 36/80 patients (45.0%) discontinued dose reduction after 19 months (95% confidence interval 14.9–23.1 months). Of 67 patients with 1-year follow-up, 45 (67.2%) still used the lower dose after 1 year. No serious adverse events related to dose reduction occurred. Cumulative dose and costs decreased by 22.7% during 1 year. In conclusion, a one-step tightly controlled dose reduction strategy for adalimumab, etanercept and ustekinumab has considerable potential to safely decrease biologic dosages in patients with psoriasis in daily practice.
