Summary
Brief summary
Poor compliance is thought to be a major cause of treatment failure. The TEddI study is a
randomised, multi-centre, open-label study in well-controlled treatment-experienced
HIV-infected patients to assess compliance with a once-daily regimen of antiretroviral
therapy versus continuation of current anti-retroviral regimen delivered at least twice
daily.
