European Medicines Agency Confirms Acceptance of Marketing Application for AVT03, a Proposed Biosimilar to Prolia® and Xgeva®

Alvotech (NASDAQ: ALVO), a global biotech company specializing in the development and manufacture of biosimilar medicines for patients worldwide, announced today that the European Medicines Agency (EMA) has accepted a Marketing Authorization Application for AVT03, a proposed biosimilar candidate to Prolia® and Xgeva® (denosumab).

"EMA acceptance marks an important step towards making AVT03 available to patients and caregivers in Europe,” said Joseph McClellan, Chief Scientific Officer of Alvotech. "Successful progression in the development of multiple biosimilar candidates demonstrates how Alvotech is able to leverage its end-to-end biosimilars platform in support of broader access to affordable biologic medicines.”

Alvotech develops and manufactures AVT03. STADA Arzneimittel AG and Dr. Reddy’s Laboratories SA, have entered into agreements with Alvotech for the commercialization of AVT03, each partner with semi-exclusive commercial rights in Europe, including Switzerland and the UK.

In July 2024, Alvotech announced positive topline results from a confirmatory patient study for AVT03. The AVT03-GL-C01 study, which met its primary endpoints, demonstrated clinical similarity of AVT03 to Prolia in terms of efficacy, safety, immunogenicity, and pharmacokinetics (PK) in 532 postmenopausal women with osteoporosis. Primary endpoints were also met in both the AVT03-GL-P01 study, which assessed the PK, safety, and tolerability of AVT03 compared to Prolia in 209 healthy adult participants, and the AVT03-GL-P03 study that assessed the PK, safety, and tolerability of AVT03 compared to Xgeva in 208 healthy adult participants.

Prolia is indicated to treat osteoporosis in postmenopausal women and in men at increased risk of fracture; bone loss in men receiving treatment for prostate cancer that increases their risk of facture; and bone loss in adults at increased risk of fractures who are treated long term with oral or injected corticosteroids [1]. Xgeva is used to prevent bone complications in adults with advanced cancer that has spread to the bone, as well as to treat giant cell tumor of bone in adults and adolescents whose bones have fully developed [2].   

Across all indications, the European denosumab market is currently valued at approximately US$1 billion [3]. Biosimilar competition to Prolia and Xgeva could expand patient access considerably at the same or lower overall costs.

In 2019 the total direct cost of osteoporotic fractures in the European Union, Switzerland and UK, was estimated at US$63 billion, excluding the individual disease burden. An estimated 32 million individuals in Europe had osteoporosis, 80% of which were women, but 70% of women eligible for treatment did not receive osteoporosis treatment [4].

About AVT03 (denosumab) 
AVT03 is a human monoclonal antibody and a biosimilar candidate to Prolia® and Xgeva® (denosumab). Denosumab targets and binds with high affinity and specificity to the RANK ligand membrane protein, preventing the RANK ligand/RANK interaction from occurring, resulting in reduced osteoclast numbers and function, thereby decreasing bone resorption and cancer-induced bone destruction [1]. AVT03 is an investigational product and has not received regulatory approval in any country. Biosimilarity has not been established by regulatory authorities and is not claimed.
