The article describes general principles of evidence-based quality assessment research of a recombinant granulocyte colony stimulating factor preparation (G-CSF) under development as well as a confirmation of its similarity to reference preparation (authorized original preparation). Since the quality of biotech preparations is determined by the manufacturing process, when developing a biosimilar one should focus on the manufacturing process details, starting from the selection of the expression system, the composition of excipients, on to the methods of isolation and purification of recombinant protein. Recombinant protein should be characterized in more details, than the quality parameters of the original preparation, included in the specification of the substance or the preparation. Comparative studies include characterization of the active substance and the assessment of the quality of the finished product. The reference preparation in the development of a biosimilar G-CSF

The paper presents the data on safety and efficacy assessment of adjuvants and vaccines with adjuvants at the stages of development and preclinical studies based on international recommendations. The presence of an adjuvant in vaccine content ensures higher expressing and prolonged specific immunity. The origin and nature of adjuvants currently used for various vaccines are different. Adjuvants can be classified by origin, mechanism of action, physical and chemical properties. The finished vaccine may contain one or more adjuvants which can be intended for one antigen or a number of antigens in vaccine content. Antigen-adjuvant combination is a key part in the production of a vaccine with an adjuvant. Due to the diversity of adjuvant nature and their physical and chemical properties and mechanisms of action, as well as to antigens in adjuvant vaccines content, it is rather complicated to plan and to conduct preclinical studies. The present article describes various aspects of preclinical studies of adjuvants and vaccines with adjuvants based on the analysis of current guidelines and requirements.

The article provides the information on issues related to the clinical use of preparations of monoclonal antibodies (MAb), and the prospects for developing preparations based on modified MAbs. MAb preparations based on recombinant proteins show the consistency of physical and chemical properties as well as high specificity. New class of preparations based on MAbs show great potential of targeted therapeutic influence on important pathogenetic mechanisms of disease development. It has proved to be successful against severe chronic diseases such as autoimmune cancer, infectious and allergic diseases, as well as in transplantation for the treatment and prevention of transplant rejection. The development and manufacture of MAb preparations based on a whole immunoglobulin molecule, as well as preparations of modified antibodies with a specific set of functions associated with individual structural elements of the molecule is now possible due to genetic engineering and transgenic animals technologies. Preparations based on modified MAb can exist in

The analysis of patent and scientific literature on the production of biomedical cell-based products (BMCP) showed that the main patentable developments in this sphere are focused on organ and tissue recovery, preventing transplant rejection and characterization of cell line viability. The researchers have revealed recent tendency for replacing the clinical use of BMCP based on unmodified cells and human cell lines by their genetically modified derivatives. Several dozens of Western companies are the principal developers, holding key patents in this field. At the same time, the analysis of patent activity showed that the technology of BmCp reached its peak of the development in 2000-2010, but many issues related to their safety clinical practice has not been solved yet. The examples of the mentioned issues are low efficiency of implanted cell differentiation maintanance; the possibility of BMCP contamination with infectious agents; nonspecific immunosuppressive effect on recipient organism; poor control of gene expression in transplant cell lines differentiated in a target organ and some

Using the example of Herceptin (Roche) a method of assessing the antiproliferative activity of monoclonal antibodies using tetrazolium salt was developed. The method is based on spectrometric measurement of the level of formazan transformed by living cells from a water soluble salt XTT. The level of formazan is proportional to the number of viable cells. The technique was in terms of specificity, calibration curve, accuracy and precision.

The article presents an analysis of 522 cases of complications after BCG vaccination, i.e. post-vaccinal osteomyelitis, based on pharmacovigilance data obtained between 2001 and 2012. A detailed study of ill children revealed no clinical manifestations (severe bacterial, viral or fungal infections, repeat bacterial infections of respiratory tract, paraproctitis, chronic eczema etc) suggesting primary or secondary immunodeficiency. All of the 135 children who were vaccinated with measles, mumps and rubella vaccine and all of the 315 children who were vaccinated with live polio vaccine had no complications in the post-vaccinal period.
