Types of Preclinical Safety Studies • Repeat Dose Toxicity • Animal models •Small molecules – two species (one rodent, one non-rodent) •Biologics – may require only one species if only one relevant species can be identified • Should mimic as closely as possible the planned clinical design •Route •Duration •Schedule

these two doses should be chosen for the high dose group in preclinical toxicity studies unless there is a justification for using a lower dose (e.g., maximum feasible dose).

toxicity profiles across species, including human. Toxicities are easily predicted, monitored, and are reversible. Dose-response for toxicity is not steep. The NOAEL upon which the HED is based was determined in longer-term nonclinical studies; this assumes that toxicities are cumulative and were not observed early in the longer-term studies.

Toxicity . Desired . Efficacy (eg ED 90) Acceptable . Toxicity (Normally the ‘ No observed adverse effect level ’ or NOAEL) Safety Margin . Aim of Preclinical Testing is to Determine Safety Margins . Safety margin (SM) calculation: Exposure at the NOAEL = SM . Predicted exposure required for clinical efficacy
