Care and Prevention in HIV Vaccine Trials: a site perspective Guy de Bruyn Perinatal HIV Research Unit University of the Witwatersrand Chris Hani Baragwanath Hospital Johannesburg, South Africa

Access to care (modified from Grady) Care which is part of the scientific design Care needed to safely complete the trial Care for injuries and adverse events Post trial access Ancillary care –Care that some participants will predictably need

Dialogue? “a comprehensive care package should be agreed upon through a host/community/sponsor dialogue which reaches consensus prior to initiation of a trial” (UNAIDS 2000, #16)…

Protocol mandates Avoiding pregnancy during the vaccination period Assessing symptoms of illness Ensuring adequate standard of care to control participants –Counselling – pre/post-test, risk reduction, safer sex –Providing condoms

Care needed to safely complete the trial Resuscitation equipment Laboratory monitoring of haematologic parameters and other clinical laboratory values of potential interest –Anaemia –Leukopaenia –Alteration of hepatic enzyme tests

Ancillary care in HIV Vaccine trials Some questions –What kind of care is needed? –For how long? –By whom? –Whose responsibility?

Ancillary care – some examples Hypertension –May be diagnosed incidentally during the conduct of trial procedures –Treatment is lifelong –Management is multi-modal, i.e. requires attention to weight, nutrition, exercise, in addition to possible pharmacotherapy Facilitating access to services –TOP –Psychosocial support – rape/trauma/DV –Mental illness Dental care

What is “the standard of prevention”? HIV counseling and testing –Some protocols may not provide results in ‘real- time’, depending on the complexity of ruling out vaccine-induced seropositivity –Impact on testing outside of the trial setting Other VCTs, blood donation, organ donation, testing for insurance purposes –What about partners? Should we offer CHCT and who is able to do that?

More “Standard of Prevention” Risk reduction counselling –Efforts to standardize that intervention, such as pilot efforts within DAIDS networks Condom promotion vs. provision –Male / Female / both –What other means should be used to promote condom uptake

What about additional HIV prevention technologies? Male circumcision STI treatment –Diagnostics –Directed versus syndromic therapy Post-exposure prophylaxis Pre-exposure prophylaxis Other investigational agents

What is the Threshold of Evidence for New Prevention Tools?
