02645 DO SITE FEASIBILITY STUDIES CONTRIBUTE TO THE PLANNING OF PHASE III MICROBICIDE TRIALS? Naiker, Shamantha Background The high cost of Phase III microbicide trials require careful selection of clinical sites capable of meeting the study end points. The current trend is to conduct site feasibility studies to ascertain site capability, adequate clinical and laboratory infrastructure, trained professional staff, adequate at risk population, baseline behavioural characteristics, high HIV prevalence and incidence rates and high retention rates. Objective To describe the challenges and the lessons learnt from the microbicide development program funded feasibility study undertaken at 2 sites in Durban. Results The sites selected for the studies were research naïve hence community entry and education played a crucial role in getting approval and support for developing infrastructure. Enormous amount of time was invested in basic education of HIV/STD, prevention strategies, ethics of research and the role of microbicides to not only the community but service providers at clinics in and around the area. Recruitment of trained staff was a challenge as many lacked clinical trial experience. The study initially targeted women from family health and post-natal clinics. The study generated enormous amount of interest hence recruitment was expanded to the community at large. Study specific development of case report forms was challenging as they were not only expensive but required several amendments after the study was implemented. The HIV prevalence rate in the community is high (>40%) suggesting that we had targeted the right population. The baseline behavioural characteristics were helpful in ascertaining behaviour risk factors and to develop the focus of risk reduction counseling. Retention of participants have not been difficult as the study has a high retention rate (>90%) after one year. Conclusion Sponsors should invest in site feasibility studies as they provide a trial run of the Phase III study. These studies provide an opportunity to address problems ranging from community entry to retention rates in preparation for a relatively trouble free Phase III implementation. Ms Shamantha Naiker |
