Background: The introduction of biological agents has considerably changed the treatment of moderate to severe psoriasis. So far only limited data on their cost-effectiveness exist. Objective: Determination of the cost-effectiveness of biologicals from a German third payer's perspective, assessed over a 12-week period. Methods: Efficacies of the biologicals were determined by a literature review. Treatment modalities were taken from the European S3 psoriasis guideline. Costs were calculated on the basis of the German physicians' fee schedule. Cost-effectiveness was determined and a sensitivity analysis performed. Results: Infliximab at a dose of 3 mg/kg was the most cost-effective agent, directly followed by adalimumab, infliximab 5 mg/kg and ustekinumab. The least cost-effective agent was etanercept 2 × 50 mg/week. Sensitivity analysis showed considerable overlap of the cost-effectiveness ratios. Conclusion: Under the conditions of the German health care system, biological agents for psoriasis differ in their cost-effectiveness ratios. Differences are small, however. A major limitation of the study is the short time horizon of 12 weeks.
