ALVO Alvontech

Alvotech and STADA are strengthening their existing strategic alliance for high-quality, cost-effective biosimilars by extending their partnership to cover AVT03, a clinical-stage biosimilar candidate referencing the Prolia®/Xgeva® (denosumab) medicines for osteoporosis and cancer-related bone loss respectively.

Under the terms of the agreement, Alvotech will be responsible for development and manufacturing at its state-of-the-art facility in Reykjavik, Iceland. STADA will become marketing authorization holder, upon approval of AVT03, and will assume semi-exclusive commercial rights in Europe, including Switzerland and the UK, as well as exclusive commercial rights in selected countries in Central Asia and the Middle East.

In parallel with the commercial agreement for AVT03, the two partners have agreed to extend STADA’s commercial rights to biosimilars to Humira® (adalimumab) and Stelara® (ustekinumab) to Commonwealth of Independent States (CIS) countries in Central Asia. Alvotech will also regain commercial rights from STADA to AVT06, a proposed biosimilar to Eylea® (aflibercept).

STADA’s Global Specialty Head, Bryan Kim, commented: “As European market leader with our teriparatide osteoporosis treatment, Movymia®, STADA sees a major opportunity to offer patients and clinicians a further treatment with denosumab. With a strong presence in oncology among our six currently marketed biosimilars, broadening our alliance with Alvotech enables us to direct our resources efficiently and effectively.”

Anil Okay, Chief Commercial Officer of Alvotech, remarked: “We look forward to continuing to work with STADA on increasing patient availability of more affordable biologics in the denosumab market, as we have already done with our citrate-free, high-concentration biosimilar to Humira®. This expansion of our commercial alliance further validates Alvotech’s unique focus on biosimilar development and manufacturing, strong end-to-end capability and expertise.”

Denosumab is a human monoclonal IgG2 antibody that targets the protein RANKL, which is essential for the formation, function and survival of osteoclasts, the cell type responsible for bone resorption. Increased osteoclast activity stimulated by RANKL is a key mediator of bone destruction in metastatic bone disease. Denosumab binds to RANKL with high affinity and specificity, preventing the interaction between RANKL and RANK. This leads to a reduction in osteoclast numbers and function, and a decrease in bone resorption and cancer-induced bone destruction.

An estimated 32 million Europeans, equating to 5.6% of the continent’s total population aged 50 years and older, had osteoporosis in 20192. Of these Europeans, around four in five, or 25.5 million, were female. The International Osteoporosis Foundation (IOF) calculates the total direct cost in 2019 of osteoporotic fractures in the 27 European Union member states, Switzerland and the UK at €56.9 billion (US$61.9 billion).

About AVT03AVT03 is a biosimilar candidate for Prolia® and Xgeva® (denosumab), medicines for osteoporosis and bone cancer, respectively. Denosumab is a human monoclonal IgG2 antibody that targets the protein RANKL, which is essential for the formation, function and survival of osteoclasts, the cell type responsible for bone resorption. 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.
