Abstract
The entry of the biological medicinal products (BMPs) in the clinical practice more than 10 years ago raised complex regulatory issues as well as significant pharmacoeconomic concerns, because the costs of treatment is higher than the costs of the conventional products. The “data exclusivity” of BMPs expired and biosimilar medicinal products (BSMPs) are available on the market. The market share of BSMPs is expected to increase gradually and lead to cost reductions of biological treatment.
Aim:
To analyze the availability, affordability and drug utilization of BSMPs containing monoclonal antibodies in Bulgaria.
Materials and methods:
Retrospective study of the public data from EMA, National Council on Prices and Reimbursement and National Health Insurance Fund for 2015–2019. Descriptive statistical analysis was performed.
Results and Discussion:
On the ЕU level, BSMPs with Marketing Authorization are Adalimumab, Infliximab, Rituximab, Bevacizumab and Trastuzumab. In the Bulgarian Positive Drug List, there are 12 BSMPs with the same INN, excluding Bevacizumab. The total cost of BMPs is 691 673 158 BGN – the share of BSMPs is 34 139 639 BGN (4.7%). The access of BSMPs in Bulgaria is still very limited. BSMPs are available with the lower price, but the reference products are the preferred treatment. The reason for this could be the lack of national standards for the switching/interchangeability of BMPs with BSMPs, and the prescribers distrust of the so-called replacement therapies and aggressive drug promotion to the healthcare professionals are also of great importance.
