Lhasa Limited release Acrostic: A revolutionary read-across tool for assessing nitrosamine carcinogenicity

Lhasa Limited is pleased to announce the release of Acrostic, a cutting-edge read-across tool designed to enhance decision-making in establishing acceptable intake (AI) limits for novel and untested nitrosamines.

In line with the risk-based safety assessment framework issued by regulatory authorities such as the European Medicines Agency (EMA), the US Food and Drug Administration (FDA), and Health Canada, Acrostic serves as a valuable resource to support and document the read-across assessments recommended in this guidance, which yield compound-relevant AI limits for nitrosamines with suitable analogues, complementing the CPCA approach.

Leveraging a comprehensive set of data and expert knowledge, including relevant assay data, toxicophore knowledge, and physico-chemical properties, Acrostic assembles this information into a logical and intuitive workflow for surrogate selection. This enables users to robustly and confidently assign a carcinogenic potency value to target compounds.

Dr. Adrian Fowkes, Director of Science at Lhasa is excited about the launch, stating “Acrostic represents a significant advancement in risk assessment methodologies through its purposeful workflows for evaluating nitrosamine carcinogenicity. We believe Acrostic will play a pivotal role in supporting regulatory compliance and ensuring the safety of pharmaceuticals and other chemical products.”
