In clinical development, clinical trials are usually conducted to collect data for evaluation of the efficacy and safety of test treatments under investigation. To provide accurate and reliable assessment, well-controlled clinical trials are necessarily conducted. Clinical trial process is a lengthy and costly process, which is necessary to ensure a fair and reliable assessment of the test treatment under investigation. Clinical trial process consists of protocol development, trial conduct, data collection, statistical analysis and reporting. In practice, however, some controversial issues are commonly encountered regardless the compliance of good clinical practice. These issues include, but are not limited to, (1) appropriate of hypotheses for drug evaluation, (2) the instability of classical sample size calculation, (3) integrity of randomization/blinding, (4) clinical strategy for endpoint selection, (5) impact of protocol amendments, (6) issue of multiplicity in clinical trials, (7) feasibility of adaptive design methods, (8) independence of data monitoring committee (DMC), (9) probability of success of clinical development, and (10) other commonly encountered controversial issues. In this presentation, these issues will be discussed. Recommendations regarding the resolutions of these issues are provided whenever possible.
