The global movement for registration of clinical trials was first made public in September 2004 when the first simultaneous editorial was published in New England of Journal of Medicine and 10 other medical journals that were all members of International Committee of Medical Journal Editors. The aim of this movement was to increase transparency in the conduct of clinical trials particularly by pharmaceutical companies. The rationale was the ethical obligation of those who conduct clinical trial studies to reciprocate the altruistic action of patients and other participants of clinical trials that knowingly put themselves at risk for the sake of fellow patients and human beings. Later on World Health Organization adopted the initiative and the International Clinical Trial Registry Platform was formed along with a network of Primary Registries and the WHO portal to collect the 20 minimum items of Trial Registration Data Set (TRDS) in English from the network members.

  • Please create a new record for each trial. If what you are doing is part of a bigger trial please do not create more than one record for a single trial. Note that if your trial is part of your dissertations / PhD thesis, information related to the non-trial part of this should not be entered along with the trial record. On the other hand if one big trial has become the subject of more than one dissertation/phD thesis, the whole study should be registered as a single entity and trial slicing should be avoided
