Viral Clearance Market Industry Insights & Analysis 2020 | Growth Market Reports

1. Viral Clearance Market Industry Insights & Analysis 2020 What exactly is viral clearance? The development of drugs or biological processes involves the usage of human and animal tissues/proteins. These proteins or tissues may contain viruses that can be deadly or can threaten human life. Thus, to ensure that the biological product is safe to use, elimination of virus contamination is crucial. The process of virus removal or virus inactivation is called viral clearance. Viral clearance is usually performed before phase I and phase II clinical trials. The total virus clearance validation is done before rolling out the Phase III clinical trials. To achieve the risk-free biological product, there are certain procedures that need to be followed which depends on the method chosen It’s recommended that there should be two significant steps involved in the removal or inactivation of the virus. During the early phase, the tests must be performed on enveloped viruses such as herpes and non-enveloped virus such as parvovirus. The first step in the procedure involves inactivation/removal by a chemical method and the other step includes removal by a physical setup. If viral contamination is not done properly, it can affect the raw materials, bioreactor contamination, and downstream processing in the biopharmaceutical industry. The rising prevalence of viruses such as HIV, hepatitis A, and Parvovirus B19, among others has surged the importance of viral safety. For instance, according to the study by the World Health Organization (WHO), the prevalence of Parvovirus B19 was witnessed to be 1 in 1,000-7,000 donors while for Hepatitis B it was 1 in 10,000 donors. safety. for viral 3 Viral Removal Methods/Procedures That Are Used in the Pharmaceutical Industry 1.Precipitation: This method is usually considered effective against viruses such as HAV and parvovirus B19. As compared to other methods, precipitation is difficult to model. During the process, the protein concentration, pH, and temperature are to be recorded for successful viral removal. Furthermore, the degree of contamination with supernatant should also be considered. Small and medium enterprise usually uses PEG precipitation virus kit owing to its inexpensive and time-saving nature. Some common chemical compounds that are used during precipitation are ethanol, polyethylene, and acetone. 2.Chromatography: Chromatography is used in the virus purification of protein as it can be effectively used for viruses such as parvovirus B19 and HAV. In this method, virus removal depends on the choice of buffers, proteins, and resins. Under the umbrella of the chromatography method, there are various types of methods such as ion exchange, affinity, and mixed- mode. Amongst all, the ionic exchange has been considered as an effective method. Few

Solvent/detergent has turned out to be the well- established method as it uses simple equipment and has high process recovery. The solvents and detergents being used in the market are tri-(n-butyl) phosphate (TNBP) and Triton-X compounds. After the inactivation, solvents and detergents should be removed. This method is not feasible for the removal of non-enveloped viruses. During the process, reagent concentration levels should be observed for the successful viral inactivation. 2.Pasteurization: One of the advantages of this method that it inactivates both enveloped and non-enveloped viruses. Along with this, it uses simple equipment which makes it feasible in the biopharma industry. Few protein stabilizers utilized during the process are sodium caprylate, caprylic acid, and acetyl tryptophan chemical compounds. During the process, temperature homogeneity and duration should be taken into consideration. 3.pH Treatment: Low pH and high pH are the two type of treatment which depends on the type of virus. For instance, low pH inactivation is used for the monoclonal antibody purification process while high pH inactivation is used for certain types of enveloped and non- enveloped viruses. Currently, low pH treatment is the most common viral clearance method. In this method, the equipment used are easily available and simple. The vital parameters that need to be observed are time, pH, and temperature. There are other methods such as irradiation, microwave heating, terminal dry heating, Ultraviolet-C (UVC) & high-temperature short time (HTST), and vapor heating, among others which are not
