Core Responsibilities

Primary Functions

Design, propose, and implement comprehensive nonclinical safety assessment strategies and testing programs for development candidates from discovery through post-market support.
Act as the lead toxicology representative on multidisciplinary project teams, providing expert scientific input and strategic guidance on all safety-related matters.
Critically evaluate, interpret, and summarize complex data from a wide range of toxicology studies, including general, genetic, developmental, and reproductive toxicology (DART).
Author and meticulously review the toxicology and nonclinical safety sections of global regulatory submissions, such as INDs, CTAs, NDAs, BLAs, and annual reports.
Select, qualify, and manage relationships with Contract Research Organizations (CROs), including protocol development, negotiation of study designs, and active study monitoring.
Conduct thorough human health risk assessments for a variety of substances, including impurities, leachables, extractables, and excipients, to ensure product safety.
Prepare clear and concise toxicological evaluations and position papers to address specific safety concerns or to support product claims and regulatory inquiries.
Serve as the Study Monitor for outsourced GLP and non-GLP toxicology studies, ensuring scientific integrity, protocol adherence, and compliance with international guidelines.
Analyze and integrate data from toxicology, pharmacology, and DMPK (toxicokinetic) studies to build a comprehensive understanding of a compound's safety profile.
Develop and defend scientifically-based rationales for dose selection in first-in-human (FIH) clinical trials, based on all available nonclinical data.
Proactively identify potential safety liabilities and develop and execute de-risking strategies to mitigate them early in the development process.
Respond effectively to toxicology-related questions and information requests from global health authorities (e.g., FDA, EMA) during review cycles.
Author and maintain critical safety documents, including the Investigator's Brochure (IB) and nonclinical components of product labeling.
Stay abreast of emerging toxicological sciences, new methodologies (including in vitro and in silico models), and evolving global regulatory landscapes and guidelines.
Present nonclinical safety findings and strategies to internal governance bodies, senior management, and external partners.
Participate in pathology peer reviews to ensure the accurate interpretation and reporting of histopathological findings from toxicology studies.
Provide expert toxicology support for due diligence evaluations of potential in-licensing opportunities or corporate acquisitions.

Secondary Functions

Mentor and provide scientific guidance to junior toxicologists and team members to foster their professional development.
Contribute to the continuous improvement of internal processes, standard operating procedures (SOPs), and best practices within the toxicology function.
Collaborate with cross-functional partners in chemistry, manufacturing, and controls (CMC) to address safety issues related to the manufacturing process.
Participate in scientific conferences and industry working groups, representing the organization and contributing to the broader scientific community.
