Medicare patients have low adherence to biologic drug therapy for psoriasis

About half of Medicare patients who start taking biologic therapies for moderate to severe plaque psoriasis stop within a year, according to a new study. Previous studies have found similar results among the privately insured in the United States. The new study is the first to explore this issue among the elderly and disabled who are covered under Medicare. Lack of data in this population has been a major research gap, given that such patients are often underrepresented in clinical trials.
