WHO clinical trials portal
The world health organization (WHO) search portal for clinical trials, from multiple databases.
The Clinical Trials Search Portal provides access to a central database containing the trial registration data sets provided by registries from around the world (including Japan, South Americas, etc). It also provides links to the full original records. The interface is not very comfortable since there is no way of filtering the results you get once you finished the search.
Type of information: Clinical Trials
