MedicalResearch.com: What is the background for this study?
Response: Before 2009, etanercept (Enbrel
®), infliximab (Remicade
®), and adalimumab (Humira
®) were the only tumor necrosis factor (TNF) inhibitors approved by the FDA for rheumatoid arthritis. Subsequently, 3 therapies gained FDA approval: subcutaneous golimumab (Simponi
®) in April 2009, certolizumab pegol (Cimzia
®) in May 2009, and intravenous golimumab (Simponi Aria
®) in July 2013. All 6 agents are brand-name drugs.
Our study aimed to evaluate how the prices of existing TNF inhibitors (Enbrel
®, Remicade
® and Humira
®) changed in response to the market entry of new TNF inhibitors.
