HIV Vaccine Clinical Trials
The need for community involvement
My involvement in vaccines
• I am currently working for Imperial College at St. Mary’s Hospital, London as HIV Research Manager
• At the Clinical Trials Centre we have completed 3 HIV vaccine trials and about to recruit to 4th
• All trials so far have been in low-risk healthy volunteers
• At some point in the future we hope to carry-out some large scale, “high risk” group trials
What is the community?
• What do we mean by the community?– General population?– Local population?– The elected governments?– Non governmental organisations? – HIV positive groups?– HIV positive individuals? – At risk HIV negative population,
groups and individuals?
The Community in Phase I trials• All are involved in some way in the
development of an HIV vaccine – The government must be involved by
funding/promoting HIV vaccine development
– The general population/individuals are involved by volunteering for trials
– The NGOs must be involved by reviewing the trials and publicising them
– HIV infected individuals and high risk groups currently are the least involved
Community involvement in past vaccine trials
• Community involvement has nearly all been through the HIV NGOs– their involvement has increased with
each new trial.– They have the knowledge to assess
the validity of the work. – Their endorsement gives the trials
credibility within the HIV community.– Promoting the vaccine trials within
the HIV community and the media helps with recruitment.
NGO involvement
• On a recent vaccine trial 10% of volunteers were recruited through HIV newsletters and 20% via e-mails sent around staff at NGOs
• NGOs have given advice to possible volunteers about participating in an HIV vaccine trial
• Representatives from NGOs & patient groups have attended pre-launch meetings for vaccine trials
Phase III HIV vaccine trials
• Phase III trials assess the efficacy and safety in large numbers of “high risk” population
• Phase III vaccine trials will need to recruit between 3,000 and 15,000 people to be statistically powered to prove the vaccine is able to prevent HIV infection
• In order to recruit this many volunteers many months of preparation work and promotion will be needed whether the trials are in the UK or worldwide
AIDSVAX trials
• Only two Phase III HIV vaccine trials have been completed
• Results from both were reported earlier this year– The first was in 5000 gay men and
400 women and was conducted in the USA, Canada, Puerto Rico and the Netherlands
– The second in 2500 injecting drug users in Thailand
– Neither trial was able to show that the vaccine prevented HIV infection
Future plans
• As part of the preparation for future phase III trials we will set up a Community Advisory Board.
• Information from the CAB will help develop trial strategies
• The board will include representatives from the local community, gay community, members of NGOs, public health officials and people living with HIV
• Main target group for the trials will probably be the gay community
What need to be done?
• Further development of our collaborations with the NGOs.
• Carry out some social research with them which can be developed at the same time as the trial protocols
• Introduce a participant advisory group to learn from the people who have actually taken part in a trial
Thoughts for future trials
• Are there any other ways we can increase the input of the HIV community and at risk groups in the planning and promotion of future phase I/II & phase III trials?
• Is it really necessary if there may never be a phase III trial in the UK?
• And finally…….

• We need healthy volunteers for EUROVAC II a phase I trial of an HIV vaccine.
