Virus Clearance Validation

Virus safety is one of the top concerns of biopharmaceuticals and pharmaceutical manufacturers. It needs to select clean raw materials, test and remove viruses in various production steps. Removal is the only way to prevent contamination by accidental viruses, so a reliable removal process with proper verification is essential to ensure patient safety. Alfa Chemistry can provide virus removal verification services to support biopharmaceutical companies to successfully remove viruses.

Our service provides virus spike research for purification technology, as well as expert consultation on process design and optimization. This enables biopharmaceutical manufacturers to optimize their processes and increase the potential for successful completion of GLP studies.

Why Is Virus Clearance Research So Important?

Every virus safety strategy is based on three pillars: selection of appropriate raw materials, testing of intermediate samples during production, and removal/inactivation of viral contaminants. The latter is verified by virus removal studies, which is an important part of the manufacturer's strategy to ensure product safety.

  • Patient Safety

The ultimate goal of clearing the virus is patient safety. In the worst case, the consequences of virus contamination may occur.

  • Regulatory Requirements

Virus Clearance is a regulatory requirement to ensure patient safety. To ensure that the manufacturer’s purification process can cope with unexpected situations, regulatory agencies implement three basic principles of virus safety: selection, testing, and reduction.

  • Virus Reduction

Virus clearance methods require personalized, scalable, and flexible process solutions based on different technology platforms. Our unique orthogonal virus clearance technology is characterized by virus retention filtration and membrane chromatography to clear viruses, as well as low pH virus inactivation.

How Is a Virus Clearance Validation Study Structured?

Virus clearance research can be subdivided into three stages: pre-research, main research, and report. During the cleanup study, we deliberately incorporated the purified virus stock into the starting material of the unit operation. It is necessary to select a reduced manufacturing environment model that meets the customer's process conditions.

Five basic steps of virus clearance verification research

Five basic steps of virus clearance verification research

  • According to customer requirements, research will be planned and designed
  • Customer product spike determination of the total viral load in the starting material
  • Perform a scaled-down virus removal step(s) for sample analysis
  • Determine the total viral load in the part containing the product and therefore calculate the log reduction
  • Results captured in the evaluation and creation of the verification report
