Provide scientific design, operational delivery and interpretation of toxicology studies required for Heptares development candidates derived from either internal drug discovery or by in-licensing.

Provide expert understanding of evolving methodologies in the assessment of drug toxicity and their application to development.

Reports to: Head, Preclinical Development

Key Responsibilities:

To act as a Nonclinical Safety/Toxicology Project representative to lead the scientific and operational design, conduct, implementation, and analysis of nonclinical toxicology programmes including general toxicology, safety pharmacology, reproductive toxicology and genetic toxicology, to support the progression of Heptares programs into clinical Phase I, II and beyond to NDA.

Develop and apply detailed understanding of issues in determining the safety impacts of compounds with novel pharmacology.

Engage with project teams and pharmacology to assist the prediction, interpretation and impact of PKPD modelling, toxicology findings, arising in nonclinical toxicology studies.

Work with Discovery to build the project appropriate screening cascade for the detection of possible safety risks of potential discovery candidates. Advise on, or manage, specific follow up studies.

Engage with other Preclinical Development lines, CROs and external experts regarding conduct and interpretation of both regulatory and bespoke nonclinical safety studies.

Ensure CROs are identified, selected and proactively managed, including GLP compliance, to meet the company’s objectives.

Communicate project status, progress, and potential impediments to the Head, Preclinical Development
