Upon reflection of this demand, the term exploratory clinical trial (see Subchapter 4.3) was coined, with a variety of synonyms such as physiological study and nonregulatory trial. Pathophysiological processes in conjunction with a new compound seems to be essential for the proper profiling of a new compound, even for the identification of a disease treatable by this compound. In addition to early pharmacokinetic data, understanding the mode of action, biomarker quality, or This was the background for so-called phase 0 studies in which early orientation about human pharmacokinetics could be found, for example, by microdosing (see Subchapter 4.3). Therefore, early human experience with new compounds appeared as one of main strategies to cope with that challenge, and that experience was not fully achieved by the regulatory set of mandatory studies.

Late attrition of projects is costly and time-consuming, and the need to reduce it has been the major driver behind the hype about translational medicine in industry. This somewhat idealistic linear sequence of clinical trials has grave limitations in drug development it would be fine if the success of a novel compound were granted in all cases, which, however, is not true for 99% of all projects on new compounds (see Chapter 1). Phase IV describes data from studies performed after market approval, which may be mandated by authorities to extend approval beyond preset time frames. In phase III (so-called pivotal trial), all previous data are corroborated and, thereby, finally safety and efficacy of a new drug in the given patient population are established this is the ultimate prerequisite for market approval. In phase IIa, the very important dose-finding for clinically relevantĮffects is mandatory in phase IIb, doses are applied to patients to prove efficacy and safety at a basic level (so-called proof-ofconcept). In phase II, efficacy and safety are tested in a smaller group of patients (up to 400). This is normally done using single ascending doses and multiple ascending doses studies with major interest in plasma levels, route of excretion, metabolites, and parameters of distribution.

Phase I mainly looks at pharmacokinetics in healthy volunteers (if possible exceptions for “toxic” drugs, e.g., in oncology, which have to be explored in patients for ethical reasons) to determine the fate of the drug in the human body. Typically-as described earlier-such “regulatory” trials (meaning they are demanded by authorities) are allocated to three (four) phases of clinical development. Combining Regulatory and Exploratory Trials =Regulatory authorities have issued clear guidances about the clinical studies that are necessary to support market approval of a new drug.
