GARD approved for validation within the OECD

GARD, Senzagen´s in vitro assay for sensitization, has been included in the OECD Test Guideline Programme (TGP) work plan with the TGP No 4.106. The decision was made at the WNT National Coordinators Test guideline programme meeting in the end of April. The validation process for GARD will now be initiated.

SenzaGen’s test Genomic Allergen Rapid Detection (GARD) has been reviewed by all OECD WNT (The Working Group of the National Coordinators of the Test Guidelines Programme (WNT)) task force members and has been included in the Test Guideline Programme. This means that the process of formally validating GARD can begin. The purpose of the validation process is to show that GARD is a reproducible assay that can be use by external laboratories. The assay will be transferred externally to perform a so called “ring trial”.

 - This is a very important decision for the development of GARD as an international sensitization test and we are very confident we will have a successful ring trial. Even if our customers have been convinced by the quality of our test, it will make a big difference from a regulatory point of view when the test is validated, says Anki Malmborg Hager

The GARD test has been scientifically validated and has gone through successful in house validations prior to this with industrial partners. The test assay is based on a new innovative genomic technique which is argued to be the future of sensitization testing now that animal bans are more and more prevailing. As the chemical industry needs to find accurate and reliable tests, GARD will be an important player on the testing market once it has finalised its validation.

 - The OECD WNT representatives were very interested and positive to the GARD test and to include it in the TGP workplan. The representatives also look forward to receiving information regarding the formal validation, when these results are available. The demand is high for new alternative test methods and it has been an interesting journey as a representative for Swedish Chemicals Agency (Kemikalieinspektionen) to present GARD to OECD as it has such great potential. I am very much looking forward to follow the future for this test, says Henrik Appelgren, national coordinator at Kemikalieinspektionen.

Two external laboratories will now test GARD on several different chemicals to confirm that the test is reproducible. This process has started and final validation is expected within one year.

About Us

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 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 up to 90% reliability. This compares with the current predominant test method, experiments on mice, which has an accuracy of 70-75%. 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.
