Clinical Trial Applications (CTAs) For Global Countries

Banner with Title


Clinical Trial Application (CTA) is a Regulatory dossier that is submitted to the Health Authority of the country, in which a sponsor would like to conduct clinical trials with Investigational Medicinal Products or with approved drugs to explore new indications. To obtain clinical trial authorization, a CTA application must be submitted with all the required documentation as per the regulations of the competent national Health Authority of a country. Clinical Trial regulations and safety reporting requirements for clinical trials vary from country to country across the globe. Every country has its own Regulatory framework and enforcement to authorize and monitor clinical trials.

In case of the US FDA, clinical trial applications are submitted in the form of Investigational New Drug applications (IND), whereas for MHRA (UK) and the EU Member States, such requirements include submission of Investigational Medicinal Product Dossier (IMPD) along with Clinical Trial Authorization application. For Canada and most of the world countries, clinical trial authorization application is commonly referred as Clinical Trial Application.

In general, a clinical trial application contains information on quality, safety & efficacy (or proposed therapeutic uses) of Investigational Drug. The level of CMC (Chemistry, Manufacturing and Controls) and safety/efficacy data requirements will vary based on the phase of clinical trial conducted (i.e., Phase I, Phase II, Phase III). Once submitted, CTA shall be reviewed by the respective Health Authority. Upon satisfactory review and evaluation of the information submitted in a CTA, the sponsor will receive a formal authorization from the Health Authorities to conduct proposed clinical trials. Regulatory requirements with respect to different phases of clinical trials and the type of study population are divergent in different countries in the world.

General challenges in conducting clinical trials are planning of clinical trials, CTA/IMPD/IND preparation and submission as per the country-specific regulations. In case of global clinical trials (trials in multiple countries), integration of the Regulatory process (CTA applications submission in multiple countries) with clinical material manufacturing/supply logistics & engagement with clinical trial sites is very crucial and requires prior experience and thorough knowledge on CTA filing process in each country.

Also, the right Clinical Trial Management System (CTMS) with Clinical Data Management Systems (CDMS) is essential to effectively conduct clinical trials and for clinical data management from multiple trials/sites.
