Cimzia, a medication used to treat autoimmune conditions, received its initial U.S. Food and Drug Administration (FDA) approval in October 2008 [1]. It is indicated for the treatment of moderate to severe active rheumatoid arthritis in adult patients who have had an inadequate response or intolerance to methotrexate [2].
When Else Has Cimzia Been Approved for Different Conditions?
The FDA has since expanded Cimzia's approval to cover other indications. In September 2013, it was approved for the treatment of adults with active ankylosing spondylitis (AS) who have had an inadequate response or intolerance to conventional therapy [3]. Further approval came in September 2016 for the treatment of active psoriatic arthritis (PsA) in adult patients who have had an inadequate response or intolerance to methotrexate or other disease-modifying antirheumatic drugs (DMARDs) [4]. Most recently, in January 2021, Cimzia received approval for the treatment of moderate to severe plaque psoriasis in adult patients who are candidates for systemic therapy or phototherapy [5].
What Are the Risks Associated with Cimzia?
Cimzia carries a boxed warning for serious infections and malignancy [6]. Common side effects include upper respiratory tract infections, rash, and urinary tract infections [2]. Patients should be monitored for signs of tuberculosis, as Cimzia can reactivate latent tuberculosis infections [6].
How Does Cimzia Work?
Cimzia is a tumor necrosis factor (TNF) inhibitor. TNF is a naturally occurring cytokine in the body that plays a role in inflammation. In certain autoimmune diseases, TNF is overproduced and contributes to inflammation and joint damage [7]. By binding to TNF, Cimzia neutralizes its activity, thereby reducing inflammation [7].
When Does Cimzia's Patent Protection End?
Patent protection timelines for pharmaceuticals can be complex, involving multiple patents covering different aspects of a drug, such as formulation, manufacturing, and method of use [8]. Information regarding specific patent expiry dates for Cimzia can be found through resources like DrugPatentWatch.com [8].
What Are the Treatment Costs for Cimzia?
The cost of Cimzia can vary significantly based on insurance coverage, dosage, and pharmacy. Patients and healthcare providers often explore financial assistance programs offered by the manufacturer or other organizations to help manage treatment expenses [9].
