U.S. FDA Approves Cyltezo® (adalimumab-adbm) as First Interchangeable Biosimilar with Humira®

RIDGEFIELD, Conn., Oct. 15, 2021 /PRNewswire/ -- Boehringer Ingelheim today announced the U.S. Food and Drug Administration (FDA) approved the supplemental Biologics License Application (sBLA) for Cyltezo® (adalimumab-adbm) as the first Interchangeable biosimilar with Humira® (adalimumab). The FDA originally approved Cyltezo® in 2017 for the treatment of multiple chronic inflammatory diseases and this latest approval designates it as Interchangeable across all of these indications.

"We are proud to be the company driving the advancement of biosimilars and delivering the first and only Interchangeable biosimilar with Humira®. It is a true milestone and an important step forward for broader adoption in the U.S. and for patient access to affordable medicines," said Thomas Seck, senior vice president, Medicine and Regulatory Affairs at Boehringer Ingelheim. "The Interchangeability status of Cyltezo® reinforces our goal of expanding overall treatment options and contributing to the quality and sustainability of the U.S. healthcare system."

A biosimilar is a biological medicine that is developed to be highly similar to an approved reference biologic, with no clinically meaningful differences in terms of safety, potency and purity. An Interchangeable biosimilar must first meet the high FDA standards of a biosimilar. Then, in order to achieve the interchangeable designation, the FDA requires an additional clinical study of multiple substitutions in patients, known as an Interchangeability study. This type of study shows how patients do when they are switched back and forth multiple times from a reference product to the Interchangeable biosimilar candidate. A biosimilar with an Interchangeable designation can be auto-substituted by a pharmacist for the reference product, with individual state laws controlling how and whether physicians will be notified.

"As the first Interchangeable biosimilar of Humira®, Cyltezo® (adalimumab-adbm), represents an important step toward bringing patients more affordable treatment options for complex, and often expensive, biologic reference products," said Martin Alan Menter, MD, chairman of the Division of Dermatology at Baylor University Medical Center. "This is incredibly important for patients, who can be confident that once available, citrate-free Cyltezo® has the same efficacy and safety as the originator medicine with the added benefit of cost savings."

The approval for Interchangeability was supported by positive data from Boehringer Ingelheim's Phase III randomized VOLTAIRE-X clinical trial and marks the first FDA approval for such a study. The VOLTAIRE-X trial studied the effects of multiple switches between Humira® and Cyltezo®. This additional study demonstrated that Cyltezo® is equivalent to Humira® with no meaningful clinical differences in pharmacokinetics, efficacy, immunogenicity, and safety between the switching and continuous treatment groups. The results were presented at the American Academy of Dermatology 2021 conference.

Cyltezo® is not commercially available in the U.S. at this time, but its commercial license will begin on July 1, 2023.

About Cyltezo®

Cyltezo® was approved by the U.S. Food and Drug Administration (FDA) in August 2017 for the treatment of multiple chronic inflammatory diseases including rheumatoid arthritis, psoriasis and Crohn's disease.

Patients treated with adalimumab products, including CYLTEZO, are at increased risk for developing serious infections that may lead to hospitalization or death. Most patients who developed these infections were taking concomitant immunosuppressants such as methotrexate or corticosteroids.

Discontinue CYLTEZO if a patient develops a serious infection or sepsis.

Reported infections include:

Carefully consider the risks and benefits of treatment with CYLTEZO prior to initiating therapy in patients: 1. with chronic or recurrent infection, 2. who have been exposed to TB, 3. with a history of opportunistic infection, 4. who resided in or traveled in regions where mycoses are endemic, 5. with underlying conditions that may predispose them to infection. Monitor patients closely for the development of signs and symptoms of infection during and after treatment with CYLTEZO, including the possible development of TB in patients who tested negative for latent TB infection prior to initiating therapy. 


Lymphoma and other malignancies, some fatal, have been reported in children and adolescent patients treated with TNF blockers including adalimumab products. Post-marketing cases of hepatosplenic T-cell lymphoma (HSTCL), a rare type of T-cell lymphoma, have been reported in patients treated with TNF blockers including adalimumab products. These cases have had a very aggressive disease course and have been fatal. The majority of reported TNF blocker cases have occurred in patients with Crohn's disease or ulcerative colitis and the majority were in adolescent and young adult males. Almost all these patients had received treatment with azathioprine or 6-mercaptopurine (6-MP) concomitantly with a TNF blocker at or prior to diagnosis. It is uncertain whether the occurrence of HSTCL is related to use of a TNF blocker or a TNF blocker in combination with these other immunosuppressants.
