About us

HIV-NAT is affiliated with The Thai Red Cross AIDS Research Centre in Bangkok, Thailand, with the Kirby Institute for infection and immunity in society in Sydney, Australia, and with the Amsterdam Institute for Global Health and Development in Amsterdam, The Netherlands. Since 1996 our centre has been conducting clinical research in HIV, meeting international standards, and gaining vast experience in the coordination of multicentre trials in Thailand.

Co-directors of HIV-NAT in 1998

The vision of the HIV-NAT was conceived during a meeting between Professor Praphan Phanuphak, Professor Joep Lange and Professor David Cooper in November 1995. As the directors of HIV Research Centers in Bangkok, Amsterdam and Sydney respectively, these physicians had met previously at many international HIV conferences and meetings. In light of the ongoing HIV epidemic in Thailand, they discussed a need for more affordable HIV treatments in Thailand and other resource limited settings, and the reluctance on the part of the pharmaceutical companies and other sponsors to move HIV related clinical research to areas where HIV is most prevalent. They concluded that a multi-centre clinical research organization should be established in Thailand to address these issues. HIV-NAT was founded and the first study began enrolling patients in September 1996.

Over the last 20 years, HIV-NAT has grown into an internationally recognized research organization and its core research areas include pharmacokinetics of HIV therapy, co-infections with Hepatitis B, tuberculosis and HPV, new drug development and cohort and strategic studies.

HIV-NAT’s accomplishments and activities include, but are not limited to, the following:

  • The completion of 68 studies and the coordination of 60 studies that are currently running
  • The initiation and participation in studies which have influenced Thai and international HIV treatment guidelines. It has also expanded its research scope to include sexually transmitted infections and prevention
  • The Bangkok International Symposium on HIV Medicine is the largest meeting of its kind in South East Asia and has been convened by HIV-NAT every January for the past 21 years.
  • HIV-NAT has provided HIV care services to almost 1,500 adults and almost 250 children and adolescents since its inception in 1996
  • HIV-NAT actively participates in community outreach programs and charities, to serve HIV infected children and their families in Thailand.

HIV-NAT’s long term goal is to keep setting up and participating in HIV clinical research and to provide continuous clinical care for our patients.


To conduct HIV clinical research according to internationally accepted Good Clinical and Laboratory Practice and conduct clinical intervention studies that will yield answers to locally and regionally relevant research questions and to serve as a training center in the practical, ethical and scientific aspects of HIV care and clinical trials for healthcare workers in government or university teaching hospitals and other related organizations in the region.


  • HIV clinical trials (adults and pediatrics) including TB, HBV, HCV
  • Training in HIV medicine: Annual symposium and Gilead-sponsored regional training courses for Asia
  • Training in GCP and clinical trials
  • Post-graduate studies
  • One of the NIH-sponsored CTU sites (ACTG)
