The medical community has been closely monitoring the development and approval of biosimilar drugs, which have the potential to offer more accessible treatment options for patients. Among these, the biosimilar adalimumab-aqvh (Yusimry; Coherus Biosciences) has garnered significant attention due to its biosimilarity to the reference drug adalimumab (Humira; AbbVie). This article delves into various aspects of this development, focusing on the study that confirmed their biosimilarity, and addresses some of the most common questions and outlines related to this topic.
What Makes Yusimry a Biosimilar to Humira?
Physiochemical and Functional Similarities
The study under discussion used state-of-the-art physiochemical and functional assays to compare Yusimry and Humira. It involved analyzing 17 independent lots of Yusimry and 43 lots of Humira. The structural data showed identical amino acid sequences and disulfide structures in both drugs. Although there were minor differences in some components like terminal galactorse or sialic acid, the majority of quantitative similarity criteria were met. This included size variants and charge variants, which are crucial in determining the efficacy of such biologics.
The Importance of Similar Mechanism of Action
For a biosimilar to be effectively used in place of its reference product, it must have a similar mechanism of action. In the case of Yusimry and Humira, all primary mechanisms of action criteria were met, barring some exceptions in FcγRIIIa (an Fc gamma receptor) binding in two lots of Yusimry. This similarity in mechanism of action is pivotal in ensuring that the biosimilar can be expected to perform similarly in clinical settings.
How Does Yusimry Compare to Humira in Clinical Efficacy?
Clinical Trials and Predictions
While the physical and chemical comparisons are foundational, the true test of a biosimilar lies in its clinical efficacy and safety. The study predicts that Yusimry, due to its high similarity with Humira, will show similar efficacy and safety outcomes in future clinical trials. This prediction is based on the minor differences in physicochemical attributes not affecting the functional activity of the biosimilar.
Impact on Treatment Options
The introduction of Yusimry as a biosimilar to Humira is significant, particularly for patients suffering from immune and rheumatic conditions. With its approval for conditions like plaque psoriasis, rheumatoid arthritis, and Crohn’s disease, among others, Yusimry offers a potentially more accessible treatment option due to the generally lower cost of biosimilars compared to their reference products.
What Are the Implications of Yusimry’s Approval for the Pharmaceutical Industry?
Market Dynamics and Competition
The entry of Yusimry into the market, along with other adalimumab biosimilars, marks a significant shift in the biologics market. It introduces competition, which can lead to more affordable pricing and increased accessibility for patients. The partnership of Coherus Biosciences with the Mark Cuban Cost Plus Drug Company and the subsequent legal challenges also highlight the complex dynamics in the pharmaceutical industry regarding biosimilars.
The approval process of Yusimry sheds light on the regulatory framework for biosimilars. The comprehensive analysis and stringent criteria that biosimilars must meet to gain approval ensure that these drugs are as safe and effective as their reference products. This has implications for future biosimilar approvals and the standards they must meet.
The study’s findings on the biosimilarity between Yusimry and Humira are a testament to the advancements in biopharmaceuticals. While further clinical trials are necessary to fully understand the implications of these findings, the preliminary data is promising. It paves the way for more biosimilar drugs to enter the market, potentially transforming treatment landscapes for various conditions.

What is a Biosimilar?
A biosimilar is a biologic medical product highly similar to another already approved biological medicine, known as the reference medicine. Biosimilars are rigorously tested to ensure their safety and efficacy are comparable to the reference product.
How are Biosimilars Different from Generic Drugs?
Biosimilars differ from generic drugs in their complexity and manufacturing process. While generics are almost identical copies of small molecule drugs, biosimilars are similar but not identical to complex biologic drugs due to natural variability and complex manufacturing processes.
What Conditions is Yusimry Approved to Treat?
Yusimry is approved to treat plaque psoriasis, psoriatic arthritis, rheumatoid arthritis, juvenile idiopathic arthritis, ankylosing spondylitis, Crohn’s disease, and ulcerative colitis.
How Does Yusimry Compare to Humira in Terms of Safety?
Based on the study, Yusimry is expected to have similar safety and efficacy outcomes as Humira. However, ongoing and future clinical trials are necessary for a comprehensive understanding.
Can Yusimry be Used as a Direct Substitute for Humira?
While Yusimry is a biosimilar to Humira and is expected to perform similarly, the decision to use it as a substitute should be made by healthcare professionals considering individual patient needs.
What are the Potential Benefits of Using Yusimry Over Humira?
The main benefit of using Yusimry over Humira could be cost-related, as biosimilars are generally less expensive. However, individual efficacy and tolerance should also be considered.
What Does the Approval of Yusimry Indicate About the Future of Biosimilars?
The approval of Yusimry indicates a growing acceptance and trust in biosimilars, suggesting a future where more such alternatives are available, potentially lowering treatment costs and increasing accessibility.
