The first-ever biosimilar of original medicine for osteoporosis treatment has been approved in the Russian Federation

The medicine will make the cutting-edge treatment more affordable for millions of Russians
Moscow, April 2025. — The Ministry of Health of Russia has granted marketing authorization for Forsedeno® (INN denosumab), the country’s first-ever biosimilar of the original targeted medicine used to treat osteoporosis. This average prevalence of this condition in Russia is 30% among subjects aged above 50 years. Petrovax Pharm is launching Forsedeno® in the Russian market and intends to supply the biosimilar at a lower price compared to the cost of a medicine containing the same active ingredient.
Osteoporosis is often called a «silent epidemic» because it can progress undetected for a long time. 14 million people in Russia suffer from osteoporosis[1], including 34% of women and 27% of men over 50 years of age[2], but the disease can occur in younger people. The disease destroys bone tissue and can result in severe fractures, loss of mobility and disability[2]. Treating osteoporosis with different medications, including denosumab, can increase bone mineral density and significantly reduce the risk of fractures[2].
Denosumab is a complete monoclonal human antibody that inhibits the RANKL activator receptor and prevents bone tissue degradation[2].
The rights to denosumab biosimilar in Russia were acquired by Petrovax Pharm based on a licensing agreement with AryoGen Pharmed (part of CinnaGen Group), outlining a subsequent full localization of production facilities. Comparable clinical efficacy of the denosumab biosimilar compared to the reference medicine Prolia was confirmed in a phase 3 multicenter, double-blind, randomized clinical study[3]. More than 50,000 osteoporosis patients have already received successful therapy with the biosimilar.
Reference information
Forsedeno® (INN denosumab) is a protein and essentially a complete human monoclonal antibody that inhibits the activity of RANKL (receptor activator of nuclear factor kappa-beta ligand), a key molecule in the formation of osteoclast — cells responsible for resorbing bone tissue during bone metabolism by dissolving its mineral component[3]. By blocking the activity of this protein, denosumab inhibits osteoclast formation, function and survival and thus reduces the intensity of bone resorption (degradation). This results in a rapid increase in bone mass in all parts of the skeleton and a decreased risk of vertebral and non-vertebral fractures.
The medicine Forsedeno® is available in prefilled syringes and is used to treat
— osteoporosis in postmenopausal women (postmenopausal osteoporosis) and osteoporosis in men at an increased risk of bone fractures;
— loss of bone mass due to decreased concentrations of testosterone due to surgery or the use of medicine products in men with prostate cancer;
— bone mass loss associated with long-term systemic glucocorticosteroid therapy in adult patients at an increased risk of fracture.
