Biologics have revolutionized the treatment for severe chronic illness and rare diseases. They represent the fastest growing segment in the pharmaceutical industry. However due to high of innovator biologics, the alternate options such as biosimilars have emerged. The impending patent cliff, rising healthcare costs and increasing awareness of biosimilars among physicians are crucial factors which will drive biosimilar uptake in future. Europe has demonstrated its faith in biosimilar treatment and EMA has approved several biosimilars since 2006. Over the years, Ukraine has been a favourable market for branded generics and its evolving regulatory landscape for biosimilar approval is an indication of its preparedness to embrace biosimilars. The current survey attempts to assess the awareness of the biosimilars among Ukrainian physicians.
The last couple of decades were characterized by rapid developments in biotechnology with similar biological medicines frequently replacing conventional methods of treating the long-lasting and chronic diseases. Biosimilars are considered to be amongst the most promising frontiers in pharmacotherapy projected to reach $25 billion in global sales by 2020 . The role of biosimilars is also buttressed by rising healthcare costs, impending patent cliff and increasing awareness amid key stakeholders . The attributes of biosimilars propels more and more countries to revise their national policies in order to make the low-cost biologics a reality today. Ukraine is one of those economies that have recently opened the doors to biologics as a new generation treatment of complex diseases.
Unlike the developed economies, the pharmaceutical market of Ukraine is characterized by the significant dominance of branded generics . However, biosimilars are not considered as generics due to their molecular structure, specificity in manufacturing process and requirement for the additional data to prove similarity with the reference product. Ukraine has special marketing authorization provisions for biosimilars and it differs from that of the standard generic drug authorization . Notably, due to cost-effectiveness and proven attributes of the biosimilars in comparison to the innovator product, these products will serve as the accessible options for the physicians.
Today, there are over 300 biological medicines registered in Ukraine, and the number of biosimilar clinical trials is constantly increasing . Teva’s filgrastim biosimilar was launched in Ukraine prior to 2015 . Other biosimilars developed by foreign players are trying to enter the nascent segment of the biologics market. In this context, biopharmaceutical companies, like Sandoz (etanercept biosimilar) , Boehringer Ingelheim (rituximab biosimilar) , Samsung Bioepis (etanercept biosimilar) , Biocad (rituximab biosimilar) , and Celltrion (trastuzumab biosimilar)  have included Ukraine amid their large multinational clinical trials on biosimilars.
The Ministry of Health of Ukraine (MOH) is the regulatory authority that conducts state registration of the medicinal products (including biosimilars) in accordance with the recommendations of ‘The State Expert Center’. In Ukraine, MOH imposes a special requirement to submit additional data when applying for the registration of the biosimilars. Post expiry of the patent protection of the innovator product, the biosimilar applicant has to provide the following materials for registration of the biosimilar:
• Information on pharmaceutical, chemical and biological data, supplemented with bioequivalence and bioavailability data
• Toxicological, pre-clinical and relevant clinical data
• Information pertaining to the identification studies of the biosimilar product
• Clinical data for the biosimilar product for each of the claimed indication in case the reference product is approved for more than one therapeutic indication
In Ukraine, the issue of allowing the biosimilars in the market is regulated by the legislators or government authorities in the assembly. In January 2013, the Ministry of Health of Ukraine (MOH) has amended the Order of MOH No.426 for the registration of biosimilars. The registration process involves stringent requirements to prove the biosimilarity in terms of safety, efficacy and quality as compared to innovators. Also in July 2013, the Ukraine MOH has approved the Order No.582 to provide special guidelines on biosimilars. These special guidelines provide the requirements to address the proof of biosimilarity, manufacturing, analytical procedures and bio-activity of the biosimilar drug in comparison with the reference product .
In addition, the attractiveness of Ukraine for biosimilar manufacturers is strengthened by the tangible progress in the regulatory space. With an eye on the biosimilar guidelines in development, the Cabinet of Ministries has recently initiated changes in the Law “On Medicines”, developing new requirements to biosimilar registration dossiers to elucidate the procedure of proving bioequivalence, safety and efficacy vis-à-vis reference medicines . Furthermore, the focus of the Ukrainian legislators on the national policies to optimize healthcare costs will drive biosimilars uptake in future.
Other factors empowering biotech companies to introduce their biosimilars in Ukraine is the rising healthcare expenditure and the associated need for affordable treatment. Ukraine’s healthcare system is a mix of public and private systems, with public expenditure accounting for 57% of the total healthcare costs, and out-of-pocket funding constituting ~93% of the total private healthcare expenditure . Since the price for novel biologics in Ukraine is comparatively higher than that in the Western Europe, the Ukrainian government expresses its interest in collaborating with biosimilar manufacturers to reduce treatment costs and address the unmet medical needs . Notably, Farmak JSC was the first Ukrainian biotech company to demonstrably prove the cost advantage of biosimilars, introducing its own “replicas” of Lilly France’s Humulin (Farmasulin H) at 69% discount, Sanofi-Aventis’ Clexane (Flenox) at 70% lower price, and Johnson and Johnson’s Eprex (Epovitan) at 94% discount .
Despite of the favourable transformation processes for biosimilars, till now the uptake of these medicines among Ukrainian physicians remained limited, due to poor clinical experience and the novelty of a “biosimilar” concept. This has predefined our endeavour to understand the current level of awareness, acceptance and adoption of similar biological medicines among physicians from different therapeutic areas.
The study aims at understanding the levels of awareness of biosimilars among Ukrainian clinicians in five therapeutic areas (endocrinology, oncology, nephrology, immunology and rheumatology) to outline the development of this segment in Ukraine.
1. Study population: Based on the study objective, we have conducted a closed fixed response interview among 82 physicians in five therapeutic areas: endocrinology, oncology, nephrology, immunology and rheumatology (Figure 1).
2. Study Location:
• Berdychiv, Chernyakhiv, Chudniv, Korosten, Malyn, Novograd-Volynsk, Kyiv and Vinnitsa and Zhytomyr.
3. Sampling technique:
• Randomized sampling technique.
• Majority of samples were collected from Zhytomyr, Vinnitsa, Kyiv region due to relatively high demand for biologics and favourable marketing condition.

o Question (1-3): The purpose of the first three questions was to determine the percentage of patients undergoing treatment with biologics, or eligible for this therapy
o Question 4 enabled us to estimate the level of awareness on biosimilars among the studied population
o Question 5 helped us to identify the most prominent sources of information on similar biological medicine
o Question 6 was aimed at measuring the probability to prescribe biosimilars
o Question 7 enabled us to identify the key motives to prescribe similar biological medicines
o Question 8 enabled us to understand an anticipated price difference between biosimilars and reference biologics
The data from the interviews was recorded and analysed on a spread sheet, and graphically represented in the forms of charts. The result is described in this section with analysis of critical questions to meet the study objectives (Figures 2-6).
Despite of attractiveness of the Ukrainian low-cost biologics market, the study suggests low to medium levels of biosimilar awareness among practitioners in five therapeutic areas. Also, the exposure towards recent developments in biosimilar monoclonal antibodies is also limited which was evident from the analysed responses of immunologists and oncologists. Among those specialists who expressed their willingness to prescribe, are also strong advocates of affordable prices to address the need for low cost biologics. This suggests that biosimilar manufacturers need to spend more effort to educate physicians and address their concern not only pertaining to safety and efficacy but also the cost effectiveness of biosimilars. Unless the above issues are not resolved, it would be difficult to obtain physician’s acceptance in Ukraine to prescribe biosimilars.
