For Etanercept Nonresponders, Switch or Escalate?

LISBON – Switching to adalimumab in psoriasis patients who are not responding adequately to etanercept is significantly more cost effective than escalating the etanercept dose, an analysis has shown.

During the first 6 months following the decision to either switch or escalate, 372 etaner cept (Enbrel) dose escalators incurred an adjusted average of $2,451 more in incremental total health care costs than the $12,943 average in 728 patients who instead switched to adalimumab (Humira), Dr. Kim A. Papp reported at the annual congress of the European Academy of Dermatology and Venereology.

Driving the markedly higher total costs in the etanercept dose escalation group was their significantly greater utilization of both inpatient and outpatient services, including urgent care. Also, psoriasis drug costs, which accounted for 75% of total health care costs, were significantly lower in the group that switched to adalimumab. The cost of adalimumab over the course of 6 months averaged an adjusted $1,573 less per patient than etanercept therapy, according to Dr. Papp, director of research at Probity Medical Research in Waterloo, Ont.

Subjects for this analysis were drawn from the MarketScan and Ingenix Impact National Managed Care databases. All participants were etanercept-treated psoriasis patients with full health care utilization and cost data accessible for the 6 months immediately before the escalate or switch decision and for 6 months afterward.

The two groups had nearly identical total health care costs during the baseline first 6 months: an average of $11,264 in patients prior to etanercept dose escalation, compared with $11,628 in those who went on to switch to adalimumab. The two groups were similar in age, sex, and comorbidities. However, the switchers appeared to have more severe psoriasis. They had a greater prevalence of psoriatic arthritis. Moreover, during the baseline period, they had significantly more outpatient visits, and 41% of them used antimicrobial medications, compared with 33% in the dose escalation group. These potential confounders were adjusted for in the analysis.

This switch or escalate decision point is a common but underappreciated aspect of etanercept therapy. Prior studies have established that 30%-50% of psoriasis patients placed on etanercept require a dosing increase during the first year of therapy, according to Dr. Papp.

This study was funded by Abbott Laboratories. Dr. Papp disclosed that he serves as an adviser to Abbott as well as numerous other pharmaceutical companies funding psoriasis research.
