In a recent Lhasa Limited webinar, experts from BfR (the German Federal Institute for Risk Assessment), Syngenta, and Lhasa came together to explore how in silico tools are being used to support genotoxicity assessments. The session delivered a thorough overview of how these advanced computational methods are applied in both regulatory and industry settings, focusing

The ICH M7(R2) Guideline (2023) continues to recommend the bacterial reverse mutation assay (Ames test), conducted in accordance with OECD 471, as a primary tool for assessing the mutagenic potential of pharmaceutical impurities, including nitrosamines. While the Ames test is generally predictive of rodent carcinogenicity, concerns remain about its sensitivity under standard conditions, particularly when

The use of in silico prediction systems has become an essential part of regulatory submissions when assessing the genotoxic potential of chemicals. Guidelines such as those from the EMA, US FDA, and ICH highlight their importance. Most notably, the ICH M7 guidance explicitly requires the application of two complementary quantitative/qualitative structure-activity relationship ((Q)SAR) systems to

For over four decades, at Lhasa Limited we have been developing scientific software solutions that enable scientists to make informed decisions on the safety of drugs, chemicals and cosmetics. Our journey advanced significantly with the creation of Derek Nexus, an in silico expert knowledge-based toxicity prediction tool. As regulatory landscapes evolved and the push for
