SenzaGen and AstraZeneca initiate technology development collaboration

SenzaGen has signed a collaboration agreement with the global biopharmaceutical  company AstraZeneca. The collaboration focuses on  testing and development of SenzaGen’s sensitization test GARDair, in order to distinguish between allergens and irritants in the respiratory tract. The goal is the validation of in vitro toxicological tests that could be applied to the discovery of new treatments for respiratory diseases without respiratory tract irritancy as a side effect.

 

The collaboration means that SenzaGen will use its leading technology platform GARD, with the help of AstraZeneca’s well-documented substance libraries, to develop a new genomic signature to distinguish allergens from irritants in the respiratory tract, something which is not possible today with in vitro methods. GARD examines and finds allergens in chemicals and medicines through a unique technology in accordance with the international 3Rs principle, Reduce, Replace and Refine, as an alternative to animal testing.

“During our research and drug discovery activities, it is important to be able to identify and mitigate potential toxicological issues as early as possible, to ensure our novel candidate drugs have the right safety profile for patients. This requires in vitro toxicological methods that are properly validated for their predictivity of clinical toxicity and that are compatible with integration into the drug discovery process. By combining SenzaGen’s technological expertise and our experience with inhaled compounds, we aim to develop a novel method to investigate whether novel drug-like molecules induce similar genomic signatures as known respiratory irritants. That could ultimately be applied to steer away from a potential irritancy hazard and enable the discovery of safer drugs for patients’” says Jorrit Hornberg, Director of Discovery Safety at AstraZeneca Gothenburg.

With this new agreement SenzaGen is initiating yet another important development collaboration with the pharmaceutical industry. SenzaGen’s focus is on introducing its tests into the pharmaceutical industry and on striving to demonstrate that there are safer and more accurate tests than those that use animals.

“This collaboration with AstraZeneca is a milestone for SenzaGen. It shows that leading pharmaceutical companies see the potential of next-generation testing and that this testing has considerable industrial value. Furthermore, the collaboration will provide SenzaGen with valuable knowledge and will help to refine and develop our GARD test for further commercial opportunities,”says Anki Malmborg Hager, CEO of SenzaGen.

The research project will run for 12 to 18 months and is in collaboration with AstraZeneca Gothenburg, contributing to the EU Horizon 2020 project granted to SenzaGen for the development of in vitro respiratory sensitization test.

About GARD
GARD is a group of tests for assessing chemical skin sensitizers. The tests make use of genetic biomarkers for more than 200 genes which cover the entire immune reaction and are relevant to predicting the risk of hypersensitivity. The tests have 90% reliability. This compares with the current predominant test method, experiments on mice, which has a reliability rating of 72%. SenzaGen’s tests are also capable of measuring the potency of a substance’s allergenic properties. Consequently GARD tests provide a much more comprehensive basis for determining whether a substance should be classified as an allergen than current testing methods.

About SenzaGen
SenzaGen makes it possible to replace animal experiments with in vitro genetic testing to determine the allergenicity of the chemicals we come into contact with in our daily lives, such as for example in cosmetics, pharmaceuticals, food products and dyes. The company’s patented tests are the most reliable on the market and provide more information than traditional evaluation methods. We ourselves sell the tests in Sweden and the USA, and we sell through partners in several other countries. Over the next few years the company will expand geographically, make alliances with more distribution partners and launch further unique tests. SenzaGen has its headquarters in Lund in Sweden and a subsidiary in San Francisco, USA. For more information visit www.senzagen.com.

SenzaGen introduces GARDpotency – a unique method for measuring the allergenicity of chemical substances

SenzaGen AB announces today the start of pilot sales of GARDpotency, the first animal-free method of analysis that can provide invaluable information on the allergenic potency of a chemical substance. GARDpotency is a unique complement to the previously launched test method GARDskin.

For a long time there has been huge demand from government and industry to be able to quantify the strength of chemicals’ allergenicity. SenzaGen’s new in vitro test method GARDpotency makes this possible for the first time. Quantitative information is a requirement of REACH, the EU chemicals regulation, and is of great help to companies that develop new cosmetics, pharmaceuticals and food products. Until now all testing for potency classification has been carried out on animals.

As a first step in the launch of GARDpotency, SenzaGen will present the test method for potential customers in connection with the Society of Toxicology’s annual conference 12-16 March 2017 in Baltimore, USA. The technology behind GARDpotency has been developed by a research group at Lund University. At the conference, which brings together around 6,500 toxicologists from more than 60 countries, the research team will present two scientific papers describing GARDpotency as well as new application areas for GARDskin. Summaries of the research results will soon be made available and will also be available on the SenzaGen website after the scientific publications are published.

“We see great market potential for GARDpotency. It is already possible to determine if a chemical can cause allergies, but there is a significant additional need among both manufacturers and regulatory bodies to be able to quantify how strong the allergenic effect is. Until now no animal-free testing has been available and we are extremely proud to be the first to offer this to the chemicals industry” says SenzaGen’s CEO, Anki Malmborg Hager.

GARDskin is scientifically validated and has been approved for validation in accordance with OECD requirements on allergy tests. The test provides greater than 90 percent accuracy in the classification of allergenic substances.

Summary

Chemical hypersensitivity is an immunological response towards foreign substances, commonly referred to as sensitizers, which gives rise primarily to the clinical symptoms known as allergic contact dermatitis. For the purpose of mitigating risks associated with consumer products, chemicals are screened for sensitizing effects. Historically, such predictive screenings have been performed using animal models. However, due to industrial and regulatory demand, animal models for the purpose of sensitization assessment are being replaced by animalfree testing methods, a global trend that is spreading across industries and market segments. To meet this demand, the Genomic Allergen Rapid Detection (GARD) assay was developed. GARD is a novel, cell-based assay that utilizes the innate recognition of xenobiotic substances by dendritic cells, as measured by a multivariate readout of genomic biomarkers. Following cellular stimulation, chemicals are classified as sensitizers or non-sensitizers based on induced transcriptional profiles. Recently, a number of animal-free methods were comparatively evaluated by Cosmetic Europe, using a coherent and blinded test panel of reference chemicals with human and local lymph node assay data, comprising a wide range of sensitizers and non-sensitizers. In this paper, the outcome of the GARD assay is presented. It was demonstrated that GARD is a highly functional assay with a predictive performance of 83% in this Cosmetics Europe dataset. The average accumulated predictive accuracy of GARD across independent datasets was 86%, for skin sensitization hazard. Keywords: GARD, sensitization, in vitro, predictive accuracy, alternative methods
