Clinical Trial Registry – India (CTRI) is a repository for information regarding the clinical trials that are conducted in India. The Clinical Trials Registry- India (CTRI), hosted at the ICMR’s National Institute of Medical Statistics (http://nims-icmr.nic.in), is a free and online public record system for registration of clinical trials being conducted in India that was launched on 20th July 2007 (www.ctri.nic.in). Initiated as a voluntary measure, since 15th June 2009, trial registration in the CTRI has been made mandatory by the Drugs Controller General (India) (DCGI) (www.cdsco.nic.in).
Today, any researcher who plans to conduct a trial involving human participants, of any intervention such as drugs, surgical procedures, preventive measures, lifestyle modifications, devices, educational or behavioral treatment, rehabilitation strategies as well as trials being conducted in the purview of the Department of AYUSH (http://indianmedicine.nic.in/) is expected to register the trial in the CTRI before enrollment of the first participant. Trial registration involves public declaration and identification of trial investigators, sponsors, interventions, patient population etc before the enrollment of the first patient. Submission of Ethics approval and DCGI approval (if applicable) is essential for trial registration in the CTRI. Multi-country trials, where India is a participating country, which have been registered in an international registry, are also expected to be registered in the CTRI. In the CTRI, details of Indian investigators, trial sites, Indian target sample size and date of enrollment are captured. After a trial is registered, trialists are expected to regularly update the trial status or other aspects as the case may be. After a trial is registered, all updates and changes will be recorded and available for public display.
Being a Primary Register of the International Clinical Trials Registry Platform (ICTRP) (http://www.who.int/ictrp/search/en/), registered trials are freely searchable both from the WHO’s search portal, the ICTRP as well as from the CTRI (www.ctri.nic.in).
Trials registered in CTRI will be monitored to ensure increasing voluntary disclosure of all items in the register. These items have been selected in order to:
Improve transparency and accountability: By disclosing all required details of the protocol of trials, public confidence in clinical trials is likely to be enhanced.
Improve the internal validity of trials: Empirical research has shown that some aspect of the methods of the trial are particularly important to produce reliable results by minimizing biases, confounders and the effects of chance or coincidence. These include the method of random sequence generation, adequate concealment of allocation of participants to interventions, adequate blinding of participants, investigators and outcome assessors, and inclusion of all participants’ results. The CTRI hopes that these items, though not mandatory at present, will be disclosed by all registrants, as incorporating such elements at the protocol stage is likely to increase the internal validity of the trial and also increase the chances of publication in a high impact journal that endorses the ICMJE requirement of reporting trials in accordance with the CONSORT statement.
Conform to accepted ethical standards: The Indian Council of Medical Research through its Bio-ethics initiative has developed ethical guidelines for the conduct of trials and for ethics committees. Clearance by local ethics committees is mandatory for all clinical trials and the CTRI hopes that making disclosure of ethical clearance a mandatory field for registration, it will lead to better links with the ICMR’s bio-ethics initiative.
Reporting of all relevant results of registered trials: The CTRI is working with the WHO ICTRP to ensure that results of all trials registered with the CTRI are adequately reported and publicly available.
