FDA Approves First Interchangeable Biosimilar for Humira

According to the FDA’s press release, “The U.S. Food and Drug Administration approved the first interchangeable biosimilar product to treat certain inflammatory diseases. Cyltezo (adalimumab-adbm), originally approved in August 2017, is both biosimilar to, and interchangeable with (may be substituted for),  its reference product Humira (adalimumab) for Cyltezo’s approved uses. Cyltezo is the second interchangeable biosimilar product approved by the agency and the first interchangeable monoclonal antibody. Once on the market, approved biosimilar and interchangeable biosimilar products can play a role in facilitating access to treatments for many serious health conditions.” 

Furthermore, “The FDA granted approval of Cyltezo to Boehringer Ingelheim on October 15, 2021. To date, the FDA has approved 31 biosimilar products, including two interchangeable products, for a variety of health conditions.”

This is an exciting announcement by the FDA, as competitors to the originator now have a viable path forward to make market inroads.

FDA Approves First Interchangeable Biosimilar

The U.S. Food and Drug Administration (FDA) has “approved the first interchangeable biosimilar insulin product, indicated to improve glycemic control in adults and pediatric patients with Type 1 diabetes mellitus and in adults with Type 2 diabetes mellitus. Semglee (insulin glargine-yfgn) is both biosimilar to, and interchangeable with (can be substituted for), its reference product Lantus (insulin glargine), a long-acting insulin analog. Semglee (insulin glargine-yfgn) is the first interchangeable biosimilar product approved in the U.S. for the treatment of diabetes. Approval of these insulin products can provide patients with additional safe, high-quality and potentially cost-effective options for treating diabetes.

Biological products include medications for treating many serious illnesses and chronic health conditions, including diabetes. A biosimilar is a biological product that is highly similar to, and has no clinically meaningful differences from, a biological product already approved by the FDA (also called the reference product). This means you can expect the same safety and effectiveness from the biosimilar as you would the reference product.

An interchangeable biosimilar product may be substituted for the reference product without the intervention of the prescriber. The substitution may occur at the pharmacy, a practice commonly called “pharmacy-level substitution”—much like how generic drugs are substituted for brand name drugs, subject to state pharmacy laws, which vary by state. Biosimilar and interchangeable biosimilar products have the potential to reduce health care costs, similar to how generic drugs have reduced costs. Biosimilars marketed in the U.S. typically have launched with initial list prices 15% to 35% lower than comparative list prices of the reference products.”
