Clinical Trials Registries

Clinical trial registration is one of the essential steps in the process of research planning and design. Clinical trial registries were found to reduce the publication bias related to clinical research. The WHO International Clinical Trials Registry Platform was established to allow search within the clinical trial registries included in the WHO Registry Network. This network recognize the following national and regional registries:

  • Australian New Zealand Clinical Trials Registry (ANZCTR)
  • Brazilian Clinical Trials Registry (ReBec)
  • Chinese Clinical Trial Registry (ChiCTR)
  • Clinical Research Information Service (CRiS), Republic of Korea
  • Clinical Trials Registry – India (CTRI)
  • Cuban Public Registry of Clinical Trials(RPCEC)
  • EU Clinical Trials Register (EU-CTR)
  • German Clinical Trials Register (DRKS)
  • Iranian Registry of Clinical Trials (IRCT)
  • ISRCTN
  • Japan Primary Registries Network (JPRN)
  • Lebanese Clinical Trials Registry (LBCTR)
  • Thai Clinical Trials Registry (TCTR)
  • The Netherlands National Trial Register (NTR)
  • Pan African Clinical Trial Registry (PACTR)
  • Peruvian Clinical Trial Registry (REPEC)
  • Sri Lanka Clinical Trials Registry (SLCTR)
    The value of clinical trial registration goes beyond being a trials record. The Sri Lanka Clinical Trials Registry was launched in 2006. Its contribution to the research community in Sri Lanka was credited (Ranawaka and Goonaratna, 2009). A regional clinical trials registry that can be used by researchers in African Arab countries is the Pan-African Clinical Trials Registry. The registry was praised for its role to facilitate the trial registration by African researchers. In addition, it helped to present the landscape of the clinical research agenda in the continent (Abrams and Siegfried, 2010).
    In almost all Arab countries, researchers can only register their work in other trial registries including the Pan-African Clinical Trials Registry and US Clinicaltrials.gov (Zeeneldin and Taha, 2016). The only Arab clinical trials registry is the Lebanese Clinical Trials Registry (LBCTR).
    PABRA plans to launch the Pan-Arab Clinical Trials Registry in the near future. Be ready.
