Phase II.

This video explains the three main phases of clinical trials. Clinical trials to test new cancer treatments involve a series of steps, called phases. If a new treatment is successful in one phase, it will proceed to further testing in the next phase. During the early phases (phases 1 and 2 Clinical Study Phases Clinical studies, which test interventions in people, occur in several steps, known as phases. While each phase is designed to answer different research questions, studies in all phases evaluate the safety of the intervention.

Feb 15, 2015 · Phase I Study/ Clinical trial • The aim of a Phase I trial is to determine the maximum tolerated dose (MTD) of the new treatment. • The MTD is found by escalating the treatment dose until the dose-limiting toxicity (DLT) is reached.

Clinical trials may go so wrong that unplanned changes in the population studied, end points or analysis plan must be made [20]. Understanding the basis of clinical trial phases will help researchers plan and implement clinical study protocols and, by doing so, improve the number of therapies coming to market for patients. 2.
