Statistical Consulting

One of the important steps in the medical devices, biologics and drug development process is the demonstration that it is safe to administer the product to humans for the first time (Phase I). The process is especially difficult because this demonstration of safety is most often limited to the use of preclinical in vitro and in vivo studies, including animal toxicology studies. In order to carry out this task, consideration must be given to the FDA regulatory process, the appropriate FDA and ICH guidance’s, general principles related to proper toxicology study design, specific safety considerations related to the biological product or drug class, additional safety concerns obtained from a careful scientific review of the pharmacodynamics and mechanism of action of the product, and an analysis of the risk-benefit issues associated with the product. The product development cannot proceed until preclinical toxicology study results that support safe administration of the product to humans are submitted to the FDA in a 510(k) or an IND. It is recommended this process involve continuous communication with the FDA, including a pre-IND meeting.
