Dual biologic therapy for the treatment of rheumatic diseases and asthma: a case series

Abstract

Objective: Combination biological therapies are being considered increasingly for patients with multiple co-morbidities requiring biologics. There are limited data available on this approach, and concerns remain about the possible risk of adverse events, particularly infection.
Methods: We present three patients on dual biologics for rheumatic disease and asthma. The biologic combinations used were etanercept and mepolizumab, infliximab and omalizumab, and etanercept and omalizumab. The time on combination biologic therapies ranged from 24 to 36 months. Patients were monitored for any serious adverse events.
Results: All three patients were able to tolerate combined biologic therapies, with no serious adverse events. All three patients gained improvement in their rheumatic and asthma disease control, with reduction in disease activity scores and reduction in steroid usage.
Conclusion: The decision to start dual biologic therapy should be considered carefully, on a case-by-case basis. The number of patients who are on combination biological therapy is small, and data are sparse. Real-world data are needed to examine the long-term benefits and risks of different forms of combination biologic therapies.
