EXHIBIT 99.1
Alvotech announces European launch of first-in-market biosimilar to Simponi® (golimumab) globally by partner Advanz Pharma
REYKJAVIK, Iceland, Dec. 22, 2025 (GLOBE NEWSWIRE) -- Alvotech (NASDAQ: ALVO), a global biotechnology company specializing in the development and manufacture of biosimilar medicines for patients worldwide, today announced that launches are underway in Europe for Gobivaz® (golimumab), Alvotech’s biosimilar to Simponi® (golimumab), also known as AVT05 (prefilled syringe and autoinjector). Gobivaz is the first marketed biosimilar to Simponi worldwide. It is being commercialized exclusively in Europe by Alvotech’s partner, Advanz Pharma Holdco Limited (“Advanz Pharma”).
In the United Kingdom, the introduction of Gobivaz is supported by a National Health Service (NHS) England tender award. This procurement decision provides a defined framework for adoption within NHS services and reflects the system’s focus on improving access to high quality biologic treatment options for immune mediated inflammatory diseases.
Availability across EEA markets will progress in line with national pricing and reimbursement processes.
“We welcome the introduction of Gobivaz into clinical practice across Europe following its approval as the first biosimilar to Simponi worldwide,” said Robert Wessman, Chairman and Chief Executive Officer of Alvotech. “Our biosimilar represents an important treatment option for patients, and the NHS England tender supports our aim of expanding the availability of high-quality biologic medicines.”
Approval of Gobivaz was supported by comprehensive analytical, pre-clinical and clinical studies that demonstrated biosimilarity to the reference product. Gobivaz is available in the same presentations and dosage forms as Simponi and is manufactured at Alvotech’s facility in Iceland.
