Clinical Trials
Experimental treatment studies on patients are recognised as clinical trials. Clinical trials are usually studies of the safety and/or effectiveness of new drugs being tested on human patients.

All clinical trials or studies are divided into different phases:
Phase I trials usually disclose a group including only a small number of people and test how new drugs or procedures should be administered.
Phase II trials provide information prior to apply about whether or not a new drug or procedure works and demonstrate about safety and benefit.
Phase III trials compare promising new drugs or procedures with the current standard treatment. Large numbers of people from across the nation usually hunt down to participate in Phase III trials and receive either the new treatment or the standard treatment.
