More than 300 clinical trials are currently being carried out at the NCT. Every study is conducted according to an extensive inspection plan, also called a study protocol. The plan includes the duration of the trial, the criteria for the selection of the participants, necessary tests and procedures, which medication is administered in what dosage, as well as what the medical care following the study will look like.
Clinical trials take place in phases. Every phase serves to answer specific questions. Every new type of medication is usually tested in phases I to III before the responsible regulatory agencies deem it safe and effective. The studies also are conducted according to the principles of good clinical practice, as prescribed by the authorities for the safety of patients.
