Abstract
AIM: We describe our experience of the first 10 years at the Sri Lanka Clinical Trials Registry (SLCTR). METHODS: We analyzed all trial records of the SLCTR over the study period. We collected information regarding trial characteristics and completeness of data entry in the SLCTR data set. RESULTS: During the study period, 210 trials (63% of all applications) were registered with the SLCTR. The number of registered trials showed an increasing trend over the years. All trial registrations had complete entries for all the data fields studied. Only 17.6% of the trials were registered retrospectively. All the registered trials were interventional studies, and the majority (87.6%) were randomized controlled trials. A significant proportion of trials (28.6%) were on noncommunicable diseases, and 12.4% were on pregnancy and its outcomes. Several trials (9.5%) were international collaborative studies. A majority of the Principal Investigators (70.9%) were affiliated to a university. Most of the studies (41.9%) were self-funded by the investigators. Details of ethics review committee approval were available for 96.7% of registered trials. Over a third of the registered trials (37.1%) had completed recruitment at the time of analysis. A majority of the trials (72.8%) had updated trial data since registration. CONCLUSIONS: There is a steady increase in the number of trials registered at the SLCTR. Complete entries for all the data fields were seen in all trial registrations. The SLCTR has made a positive contribution to the emergence of a healthy clinical research environment in Sri Lanka.
