In recent years, biotechnologically derived peptide- and protein-based drugs have developed into mainstream therapeutic agents. Peptide and protein drugs, as well as oligonucleotides and DNA, now constitute a substantial portion of the compounds under preclinical and clinical development in the global pharmaceutical industry. The pharmacokinetic and pharmacodynamic properties of a biotech drug determine the relationship between administered dose, resulting systemic exposure, and subsequent pharmacologic response. Pharmacokinetics, and pharmacodynamics are, therefore, frequently crucial determinants of a drug's efficacy and safety, and their evaluation is an important component during the preclinical and clinical development of a drug candidate. However, pharmacokinetic and exposure/response evaluations for peptides and protein therapeutics are frequently complicated by their similarity to endogenous peptides and proteins as well as protein nutrients. In addition, pharmacokinetic/pharmacodynamic (PK/PD) correlations for biotech drugs are frequently convoluted by their close interaction with endogenous substances and physiologic regulatory feedback mechanisms. Extensive use of pharmacokinetic and exposure/response concepts in all phases of drug development has, in the past, been identified as a crucial factor for the success of a scientifically driven, evidence-based, and hence accelerated drug development process. Thus, PK/PD concepts are likely to continue and expand their role as a fundamental factor in the successful development of biotechnologically derived drug products in the future.
