Phase I trial

Phase I trial (pronunciation: /feɪz wʌn traɪəl/) is the first step in testing a new treatment in humans. These studies test the best way to give a new treatment (for example, by mouth, intravenous infusion, or injection) and the best dose. The dose is usually increased a little at a time in order to find the highest dose that does not cause harmful side effects.
