To improve drug development outcomes, it is important to review when preclinical pharmacodynamic and safety models have successfully predicted human responses and when they have not. In a recent issue of the BJP, Bugelski and Martin examined the concordance between preclinical and human data for biopharmaceuticals targeted to cell-surface proteins. The cases are interesting and several trends emerge. The pharmacodynamics of biopharmaceuticals in non-human primates is largely predictive; the use of surrogates in rodents may be similarly predictive, allowing for more conservative use of non-human primates. While overall concordance of preclinical toxicology data and clinical safety was poor, this is largely a reflection of the immunomodulatory biology of the majority of the biopharmaceuticals evaluated. The examples show that adverse effects in animals that were the result of direct and/or exaggerated pharmacology were modelled well, but that specific infections or other indirect outcomes of immunomodulation, along with cytokine-related events, were not modelled well in preclinical studies.
