Lynn Morris

PL01.01: Prospects for an Antibody-based HIV Vaccine

Intensive efforts to develop a preventive HIV vaccine have been significantly bolstered by recent discoveries of broad and potent neutralizing antibodies in some HIV infected humans. Many of these antibodies have unusual genetic features that present a significant challenge for conventional vaccine approaches. Nevertheless, longitudinal studies are revealing how such lineages evolve and enabling the identification of germline B cells that an HIV vaccine would need to stimulate. Parallel viral genetic analysis further demonstrates how viral evolution shapes these responses. Collectively such studies in HIV- infected humans who develop broadly cross-neutralizing antibodies are providing important clues for HIV vaccine design.

PL01.02: Advances in Antiretroviral-Based Prevention Research

Antiretroviral-based HIV-1 prevention strategies — including antiretroviral treatment (ART) to reduce the infectiousness of HIV-1 infected persons and oral, topical, and injectable antiretroviral pre-exposure prophylaxis (PrEP) for uninfected persons to prevent HIV-1 acquisition — are groundbreaking new approaches for decreasing HIV-1 spread. The past three years have seen substantial advances in knowledge regarding ART and PrEP for HIV-1 prevention, including definitive demonstration in randomized trials that both ART and PrEP reduce HIV-1 risk and the development of normative guidance for prescribing these HIV-1 prevention strategies. Ongoing research into longer-acting PrEP agents could add new prevention options. There are numerous parallels in the opportunities ahead for ART and PrEP, including evaluating successful approaches to deliver these interventions to realize maximum population benefits, developing messaging that speaks to potential ART and PrEP users, understanding how sufficiently high adherence can be sustained to achieve high effectiveness, and integrating these strategies into health systems. Achieving success in antiretroviral-based prevention will demand the full force and breadth of prevention research and advocacy.

Bridget Haire

PL02.02: Working with Special Populations within HIV Prevention Intervention Programs and Trials

It is well accepted that effective HIV prevention must target the high risk populations in particular local epidemics, and that working collaboratively with these affected populations to design and deliver prevention interventions is an ethical requirement that can maximise uptake and acceptability.

In 2014, we have a greater than ever range of interventions to prevent HIV, but access, sustainability and adherence remain major issues, and there is no established optimal formula for implementing combination HIV prevention approaches in the specific population groups who need them most. In addition, some of the social and political barriers to effective implementation within key populations have become more entrenched. This poses particular problems both for ongoing research into new interventions and for programmatic implementation of proven interventions.

This plenary will look at the evidence about the use of HIV prevention in particular populations, and consider how HIV prevention research and implementation can work within a broader human rights framework that takes into account social and political barriers that affect vulnerability, sustainability and adherence to prevention interventions.

PL02.03: Tailoring Interventions to Different Populations

UNAIDS estimates there were 6,300 new infections a day in 2012, with 95% of these in low- and middle-income countries. Advances in biomedical HIV prevention are giving us hope that the HIV epidemic can be brought under control.

Since Biomedical, Behavioural and Structural interventions intersect, it is important to understand and engage the different priority populations and communities in order to tailor interventions for maximum benefit. Social behavioural, health systems, community participation, epidemic stage, and policy are some factors that will determine the benefits for priority populations of the advances made in biomedical HIV prevention. For example, in most generalized epidemics effective prevention approaches are required for women who are at a disproportionate risk of HIV acquisition for biological as well as social reasons. Mobilising and meaningfully engaging key populations, such as people who inject drugs (PWID), men who have sex with men (MSM), sex workers (SW), and the fisherfolk (FF) in some countries will take different forms in local contexts for these often hard to reach populations. For example, in our studies in Uganda among SW, interventions are provided through special clinics, staffed by skilled health workers with knowledge and understanding of the sex work milieu, offer friendly services and involvement of peers in mobilisation and follow up. For both SW and FF, localising clinics and services nearer to their places of work is essential to their involvement. For FF this includes providing services that are open hours when they are not working. Examples of other tailored programmes engaging populations such as MSM and adolescents will be discussed.

Investing resources and focusing national HIV prevention campaigns on well-defined strategies for and with populations that are key to the epidemic and key to the response will increase the potential for biomedical interventions to slow the HIV epidemic, reducing new infections.

Plenary 03: Importance of Mucosa in Prevention Research
Thursday 30 October | 08:30 - 10:00

Jake Estes

PL03.01: Utilizing NHP Models to Understand Mucosal HIV Transmission and Dissemination

Over 80% of sexual HIV-1 transmissions originate from a single viral variant, but the underlying basis for this transmission bottleneck remains to be elucidated. Nonhuman primate models of mucosal virus transmission allow opportunities to gain insight into the basis of this mucosal bottleneck. This talk will focus on studies that utilize NHP models to understand i) the host innate antiviral responses during the earliest time points after mucosal SIV challenge and ii) the lymphatic drainage pathways of viral dissemination in order to better elucidate the earliest events of virus mucosal transmission and potential intervention strategies.

PL03.03: Mucosal Immune Assays in HIV Vaccine Clinical Trials

Background: Mucosal immune responses and mucosal sampling from genitourinary (GU) and gastrointestinal (GI) tracts are at an increased focus for HIV vaccine research and development as well as other HIV prevention and treatment strategies that are targeted at mucosal surfaces. This is in realization that mucosal surface forms the major route of HIV acquisition and transmission across the world.

Collection of mucosal samples during the conduct of clinical trials is associated with significant operational challenges, expenses, as well as some risk and discomfort to study participants. It is therefore critical that appropriate measures are taken into account including, (clinical, behavioral, and demographic characteristics) from study participants so that factors that may influence mucosal immunology and thus the interpretation of assay data are efficiently captured in parallel with mucosal specimens during the conduct of clinical trials. KAVI-Institute of Clinical Research at the University of Nairobi, and others have studied the acceptability and tolerability of repeated mucosal sampling in clinical trial participants as well as other participants at low risk of HIV infection.

To this end the samples obtained were also used to establish and standardize the immune assays for adaptation in evaluation of mucosal immune responses in clinical trials.
Discussion: Repeated mucosal sampling is achievable both in HIV-infected and in healthy adult HIV uninfected clinical trials participants. The sampling methods that have been studied include saliva, oral fluids, semen, cervical, vaginal, rectal, and gut. Participants consented to most specimen collection methods with the exception of rectal sampling.
Samples obtained are of good quality for process, analysis and can be standardized for both T/B cell as well antibody assays for adaptation for use in evaluating mucosal immune responses in HIV vaccine clinical trials in addition to peripheral samples.
