Clinical Trial Application


Clinical trials are investigations in humans intended to discover or verify the effects of one or more Investigational Medicinal Products (IMPs). Requirements for the conduct of clinical trials in the EU are provided for in the Clinical Trials Directive Directive 2001/20/EC(1)which requires that any medicinal products/drugs in Phase I - IV of development must undergo a clinical trial.

Prior to the start of a clinical trial anywhere in the EU, a Clinical Trial Application (CTA) must be submitted to the appropriate Member State and approval granted before your study can commence.

Although the Clinical Trials Directive has gone some way to harmonising the rules for the approval of an EU clinical trial, there are often issues with regards to some Member States requiring additional data, timeline adherence and differences of opinion on the adequacy of CTA data.
