Assays contributing to infectious disease therapies

Recent events force the question: What is the best plan to reduce the burden of infectious disease globally through vaccination and prevention? IQVIA Laboratories has long been at the forefront, aiding in the development of new vaccines faster and with better methodologies in partnership with premier organizations focused on this task. We continue to commit to prioritizing a swift response to global threats to public health through innovation, collaboration, and action.

  • Our partner, the Coalition for Epidemic Preparedness Innovations (CEPI), has established a global network of laboratories transferring viral functional methods and reagents worldwide for rapid vaccine development. Their goal is to reduce the threat of future outbreaks and enable equitable access to lifesaving vaccines.
  • Another partner, the Bill & Melinda Gates Foundation, also aims to reduce health inequities through new tools and strategies that reduce infectious diseases, such as HIV, malaria, and pneumonia. In addition, they invest in deep technical expertise and novel platforms for vaccine development to accelerate innovation for better, faster, and affordable vaccines.
  • To ensure the limited resources for infectious disease research are put to best use, the WHO lists diseases that currently pose the greatest public health risk, such as SARS-CoV-2 (part of our collaboration efforts), Crimean-Congo hemorrhagic fever, Ebola virus disease, and Lassa fever.
  • Reducing food-borne bacterial infections is an urgent concern across the globe. Targeting specific serotypes of pathogens such as Campylobacter, Cyclospora, Listeria, Salmonella, Shiga toxin-producing Escherichia coli (STEC), Shigella, Vibrio, and Yersinia is one way to better understand outbreaks and prevention.

This capacity allows us to scale rapidly and helps control batch-to-batch variations of assay materials— crucial factors in maintaining operational excellence, high quality data, and world class science for our clients.

Integrated Vaccine Platforms

Challenges to develop suitable assays and tests increase when vaccine development is accelerated in response to emerging infectious disease threats. At IQVIA Laboratories, we develop custom assays relevant to the disease state which is further adapted as the disease evolves. This progressive approach provides an early prediction of how the vaccine translates later phase clinical trials. A successful vaccine project requires not only an experienced partner who understands the complexity presented in the research, but one that also has the capability to scale operations.

Our end-to-end translational support for your vaccine and immunotherapy programs ranges from lead compound selection to post-market registration. In addition, our innovative and fit-for-purpose working models are ideal for evaluating the efficacy and immunogenicity of your vaccine candidates needed for regulatory approvals.

Viral Functional Assays

  • Plaque Reduction Neutralization Tests (PRNT) and microPRNT – Neutralizing antibodies promote the elimination of pathogenic viruses from the body and play a vital role in antiviral response. The gold standard for determining antibody efficacy is virus neutralization. The ability to rapidly monitor the neutralizing response is crucial for the development of efficient vaccines and drugs. The microPRNT assay can be utilized for high-throughput and small volume assay conditions.  Results from this assay quantifies the number of Plaque Forming Units (PFU), which measures the reduction of PFU compared to each well report out the level of neutralization.

  • Neutralization and Microneutralization – The principle of the neutralization assay is the same as the PRNT. The readout of this test does not count the Plaque Forming Unit (PFU) as the endpoint, instead, the level of infectivity is indirectly measured by the survival of cells or utilizing reporter genes in virus such as luciferase or GFP.

  • Psuedo-particle Neutralization (PNA) – Pseudo-particles are replication-deficient viruses. These viruses can be modified to harbor the key glycoprotein from highly infectious virus and a reporter (luciferase or fluorescent protein) that can be used in the assay instead of the live virus. Infectivity of the virus can be quantified based on the reporter readout. PNA assays can be performed with lower biocontainment (Biosafety Level 2 facilities) and are a safer alternative to using live infective pathogens. Neutralizing activities are measured by the level of reporter gene expressed (luciferase or GFP) in multi-well plate readers that improves accuracy and objectivity as compared to manual plaque counting.

  • Hemagglutination Inhibition (HAI) – Many viruses such as influenza viruses are capable of inducing hemagglutination. HAI test is useful to assess functional antibody induction following an infection or vaccination.  Measurement of antibody response pre- and post-vaccination is required to understand vaccine-induced immunity.

Bacterial Functional Assays

Our functional antibody assays for bacteria include complex assays such as:

  • Serum Bactericidal (SBA) – SBA assays are used to measure the level of antibody in the serum required to kill a bacterium through complement activation.

  • Opsonophagocytic (OPA) – OPA assays quantify the amount of serum antibody required to opsonize bacteria and undergo phagocytosis in the presence of complement proteins. The proportion of phagocytic cells that engulf the bacteria is measured using automated image analysis systems.

Immunochemistry Ligand Binding Assays

  • ELISA – Enables 384 or 96-well colorimetric-mediated readouts to detect and quantify peptides, proteins, and antibodies.

  • AlphaLISA – This is a no-wash alternative to ELISA that is designed to detect a variety of samples using a simple all-in-one-well protocol. This assay requires significantly lower sample volumes (about 5 µL of sample per well) as compared to a conventional ELISA. AlphaLISA reduces hands-on steps and total assay times than ELISAs. AlphaLISA assays offer economies that increase throughput and easily automate without loss of sensitivity.

  • Meso Scale Discovery (MSD) – For highly sensitive detection of specific binding, SULFO-TAG™ antibodies are electrochemiluminescence (ECL) based system in 96-well plates. SULFO-TAG™ illuminates upon stimulation with an electrical current, allowing for amplification of signals, allowing the user to validate bindings using low concentrations of the substrate, thus allowing the user to do larger screens.

  • Luminex – Luminex uses a bead-based approach to assays. This allows them to create multiplexed assays, with beads recognizing different targets. A simple streptavidin-biotin system is then used to detect captured analytes with biotinylated antibodies. Using this analyte agonistic technology allows the Luminex platform to characterize antigens with minor interference from other antigens. In turn, the cauterization of the immune response for each antigen is more accurate, ultimately allowing the user to determine the identity of neutralizing antibodies facilitating protective immunity. This combination of ease of use and more accurate antigen screening is important when developing new vaccines dominated by combination and multivalent vaccine development platforms.

Molecular Biology

The molecular biology platform performs PCR-based assays to support vaccine studies. Our qPCR and RT-qPCR assays are used for quantification of the vaccine candidate particles (genome copies) in the samples to support viral shedding studies.

  • qPCR
  • RT-qPCR

Cell-Mediated Immunity Assays

Vaccine development and evaluations require highly sensitive and quantitative methods that can measure a broad range of molecules such as cytokines, antigenic and cellular markers. Our cellular assays include the following:

ELISpot – Enzyme-linked immunosorbent spot (ELISpot) is a highly flexible and versatile assay that can be adapted to multiple readout formats. ELISpot assays are quantitative and measure key cellular functions of immune system cells. They are useful for assessing both adaptive (humoral) and innate (cell-mediated) immune responses to a vaccine.

  • Humoral Responses (B-Cell)
  • Detection of Antibody Secreting Cells (ASC) – IgG/IgA
  • Detection of memory B-cells
  • Cell-Mediated Immune Responses (T-Cell)
  • Cytokine quantification
  • Vaccine efficacy (IFN-γ)
  • Quantify immune responses (Th1/Th2)
  • Perforin & Granzyme B
  • Cytotoxic T-cell responses

Flow Cytometry

In order to identify mediators of short- and/or long-term immunity, a robust method of identification, sorting, and characterization is needed.
