Alvotech announces a positive results from a pharmacokinetic similarity study for AVT04, a proposed biosimilar to Stelara®

Results from pharmacokinetic (PK) similarity study demonstrate bioequivalence of AVT04 (ustekinumab) to the reference product Stelara®

Alvotech Holdings S.A. (“Alvotech”), a global biotech company focused solely on the development and manufacture of biosimilar medicines for patients worldwide, today announced positive top-line results from a pharmacokinetic (PK) study for AVT04, Alvotech’s proposed biosimilar to Stelara® (ustekinumab).

The PK similarity study (AVT04-GL-101) utilized a single dose, 3-arm, parallel design to compare pharmacokinetics, safety, tolerability, and immunogenicity of a single 45mg/0.5mL subcutaneous dose of AVT04, with US-licensed Stelara®, as well as EU-approved Stelara®. The study results demonstrated bioequivalence between AVT04 and the reference products.

We are delighted at the continued progress of our pipeline of biosimilar candidates. This continued progress demonstrates the strength of Alvotech’s purpose-built biosimilar platform.

Ustekinumab is a human IgG1k monoclonal antibody that binds with specificity to the p40 protein subunit used by both the interleukin-12 and interleukin-23 cytokines. Stelara® is prescribed to treat a variety of inflammatory conditions including psoriatic arthritis, Crohn’s disease, ulcerative colitis, and plaque psoriasis. In 2021, Stelara’s worldwide net sales exceeded US$9 billion, making it one of the highest grossing biologic medicines. Teva Pharmaceuticals, a U.S. affiliate of Teva Pharmaceutical Industries Ltd. (NYSE and TASE: TEVA) is the exclusive strategic partner for the commercialization of AVT04 in the United States. STADA is Alvotech’s exclusive strategic partner for AVT04 for the European market.

We are pleased with the successful outcome of the AVT04 PK similarity study and the continued progress of our overall pipeline. We expect the results from our confirmatory efficacy and safety study for AVT04 before the end of the 2nd quarter.
