Manually-curated safety data to support target prioritisation


Throughout the drug discovery and development process, target safety assessments help with understanding the role of the drug target in normal physiology and potential unintended adverse consequences and safety liabilities when modulating the target with a chemical compound or drug (Brennan, 2017).

To support target prioritisation, we have manually curated experimental data and insights from publications and other well-known sources of target safety and toxicity data, including the ToxCast, AOPWiki and PharmGKB (Open Targets downstream analysis of the toxicity datasets).

Safety data is available on the target profile page and can be accessed to provide a systematic view of potentially relevant target safety liabilities.

Computational pipelines and datasets

Target safety datasets are mapped to the correct Ensembl gene ID and ingested during our initial pipeline steps to enrich the target annotation object. The data is available for download as part of the target core annotation from our data download page.
