Post-trial access to tested interventions: the views of IRB/REC chair, investigators, and research participants in a multinational HIV/AIDS study.

Controversy exists regarding an ethical requirement to make products proven effective in research available after the trial. Little is known about the views of several stakeholders. Phone or self-administered questionnaires were completed by 65 IRB/REC chairs, 117 investigators, and 500 research participants in a multinational HIV trial to assess their views about posttrial access to interventions proven effective in the study. A total of 83% of research participants, 29% of IRB/REC chairs, and 42% of researchers (p = 0.046) thought IL-2 should be guaranteed for every HIV-infected person in the world if proven effective. Most European and Latin American research participants thought IL-2 should be provided free, while North American, Australian, and Thai participants commonly said at a price the average person could afford (p < 0.001). Most IRB/REC chairs and researchers thought the CIOMS "reasonable availability" requirement applied to people in the country where the study was conducted and meant a drug should be available at a price the average person could afford and that host country governments had primary responsibility for making it available. Most research participants believe an HIV drug proven effective in research should be made available to everyone in the world who needs it. IRB/REC chairs and researchers were less expansive both in who and how they thought a drug should be guaranteed.
