Nonclinical Support for FDA Regulatory Documents & Submissions

Pharmaceutical and biotechnology companies often face challenges when preparing to submit drug applications for regulatory approval. Nonclinical development for regulatory documents and submissions requires extensive knowledge and expertise to efficiently bring medications to the market. Exponent scientists within the Center for Toxicology and Mechanistic Biology provide the highest quality technical, regulatory, and safety assessment services to assist our clients with issues related to pharmaceutical and biotechnology products, with a particular focus on nonclinical development and regulatory support.

About Nonclinical Safety Assessments

Nonclinical safety assessment begins with careful study design, involves the management of laboratory testing, and requires careful analysis of toxicity, safety pharmacology, and toxicokinetic data. Additionally, studies done to support an investigational or new drug application must comply with regulatory guidelines to demonstrate both the safety and efficacy of the drug. Due to the time- and cost-intensive nature of developing these types of data, it is prudent to maximize the value of the research and development dollars spent by strategizing ways to streamline studies, reduce expenses, and ensure that useful data are generated the first time around without the need for additional studies. Further, when a questionable finding arises in a nonclinical study, additional research may be required to resolve the clinical relevance of the finding.
