The Search Continues and Science Advances on HVAD 2016
Today, the US National Institutes of Health (NIH) announced that it will fund a large-scale efficacy trial in South Africa to test the prime-boost vaccine regimen that is a modified version of the RV144 vaccine that showed modest efficacy in 2009. This will be the first large-scale HIV vaccine trial to take place in South Africa in almost a decade, and an exciting development for the country and the field. In addition to the announcement, NIH also posted questions and answers about the new study.
Still have questions or want to hear more about what this all means? Then join us on Tuesday, May 31, at 10am US Eastern/4pm South Africa time (see www.timeanddate.com for the time in your area), for a webinar with Linda-Gail Bekker from the Desmond Tutu HIV Foundation and the lead investigator on the current HVTN 100 vaccine trial.
Register for the webinar here.
The announcement of the trial, known as HVTN 702, comes on HIV Vaccine Awareness Day, the annual event that allows us all to recommit ourselves to accelerate the search for an HIV vaccine. As we wrote on Monday, today and every day, we should all say, “I’m committed to ending the AIDS epidemic, and that means finding an HIV vaccine.”
The announcement that HVTN 702 will take place comes nearly seven years after the announcement of efficacy data from RV144. In the intervening years, global scientific collaborations have probed the responses from RV144 and developed plans, in combination with industry, to optimize the regimen so that it might work better, provide more durable protection and is tailored for the HIV subtype C that is most common in Southern Africa.
Today’s decision is based on an interim analysis of HVTN 100, a current trial in South Africa led by the NIH-funded HIV Vaccine Trials Network (HVTN) that is looking for immune responses and safety in South African volunteers of the modified vaccine combination. HVTN 702 will start later this year and will measure safety and efficacy in 5,400 participants.
Under the current plan, it will be at least four years before there are data from HVTN 702. Check out our new AIDS Vaccine Research Overview that shows the HVTN 100/702 trials in context of the larger field. Other HVAD materials are here. In addition, check out some of these new HVAD articles that just came out:
- Members of Vaccine Advocacy Resource Group published HIV Vaccine – Closer than ever in the South African Mail & Guardian’s Bhekisisa Centre for Health Journalism.
- Recent AVAC Fellow Anna Miti in Zimbabwe published a new blog entitled Wanted-AIDS Vaccine.
- Kate MacQueen of FHI 360 and Mitchell Warren of AVAC published a Viewpoint – HIV Vaccine Awareness Day: Sustaining the momentum – in the Journal of the International AIDS Society.
As is so often and so rightly said in this field: much accomplished; much to do!

Technology and Health Coverage
Out of all the different book and movie genres, my favorite is science fiction. There’s something about “futuristic” technology and how society reacts to it that fascinates me. So when I had the opportunity to attend the Global HIV Vaccine Enterprise’s “Innovative Uses of Technology in HIV Clinical Trials” meeting, I didn’t want to miss out. As technology and global health both expand—and in some places converge—I find myself more and more drawn to understanding how the global health field might benefit or be hindered by this growth in technology.
The meeting, which was part of the Enterprise’s “Timely Topics” series, concentrated on how using new technologies like biometrics, mobile phone messaging, cell phones, tablets and smart pill bottles could help clinicians, researchers and clients. Here are four key takeaways:
1. Just because we have technology doesn’t mean that researchers should use it. This idea was particularly stressed when discussing data collection. We now have the ability to collect responses through technologies like tablets or SMS. However, this doesn’t mean that we should disregard paper methods. Technology can be harder to use because it may malfunction, may not be viewed favorably by locals, get stolen or even be inaccessible when batteries run out or power goes out. We need to be sure that we are thinking about the usability of technologies and whether or not they truly add worth.
2. Policy needs to catch up with technology / Health technology companies need to ensure there are protocols in place: It’s scary to think that technology is often ahead of policy. Though it is perhaps impossible to think of every worst-case scenario, governments should start thinking of health privacy laws. In addition, health technology companies and those who utilize the technologies should put sound protocols in place should data be hacked or misused. Though biometrics (a technique using physical characteristics to identify a person), seems like a safer way to guard identity because the human body is unique to every individual, companies must proceed with caution and consider robust and secure measures.
3. Those working in the global health field and technologies need to work together to push companies to create compatible structures and platforms, at the very least within country: As the speakers stood in front to present, one of the repeated questions pertained to the compatibility of the different technologies or data systems. Unfortunately, not all of the software used seemed to be compatible. Though these new technologies are currently being tested with smaller populations, going forward, governments, clinical trial sites and companies need to decide on how to make these systems compatible. Otherwise, data sets may not be transferrable and money wasted on either starting from scratch or having someone convert data.
4. Messaging needs to be well thought out and expectations managed: I’m a big proponent of using technology to improve global health. However, I also know that transparent communication is key to growing relations and trust. That’s why I was a little bit wary as to the messaging that is potentially being conveyed when introducing something as new as biometric scanning. Are the possible cons of biometrics thoroughly listed out before participants willingly give up scans of their eyes or finger prints? Are donors and implementers aware of the responsibility and gravity of what will happen if the information were ever to get into the wrong hands? After all, things like our eyes and fingerprints cannot be reset like passwords can.
The conference was eye-opening to the different ways that technology can impact global health. The convergence of technology and health is definitely a growing field that we should be watching out for in excitement. However, we also need to pause and think before jumping into new innovations.

Introducing the VARG: Focusing local lens on global advocacy for HIV vaccines
It has been said that advocates haven’t played a strong enough role in the HIV vaccine field. While this could be debated, it is true that the role of a vaccine advocate is complicated. How can advocates push to support slow-paced, expensive science, that over its history can be seen as having more low points than highs?
These questions and this conundrum simply highlight the need for focused, strategic advocacy to push forward the goal of vaccine development.
Two weeks ago, a group of HIV vaccine advocates known as the Vaccine Advocacy Resource Group (VARG) came together in Johannesburg to meet this need. They discussed the field, dialogued with researchers, and aired concerns and questions about the field’s current status and key developments. The VARG is a global team of AIDS prevention research advocates—made up of 11 individuals from countries key to vaccine research and well connected in those countries to broader HIV advocacy. Since its formation in 2012, the VARG has been convened virtually, and the chance to meet face-to-face for the first time could have been one of the reasons the room buzzed with excitement as the meeting began.
Another reason for the buzz could have been the current state of the field. With vaccine (P5 and Janssen) and antibody research (VRC01-AMP study) fields at exciting junctures, VARG members had a lot to discuss. Some of their questions included:
- What will the results of the AMP study mean for the future of passive immunization? And for vaccine development? Will people really sit for an infusion for 30 to 60 minutes?
- Why is there so much attention around the go/no-go decision making criteria in HVTN 100? What happens if the data indicate a no-go for HVTN 702?
- Would the Clade C vaccine to be tested in HVTN 702 be relevant to other regions? What would the implications be for other countries if the vaccine is found efficacious in South Africa, the only country where 702 would be conducted?
- How are vaccine research groups addressing the inclusion of PrEP in efficacy trials? How will stakeholders be involved as trials are planned and PrEP rollout evolves globally?
Vaccine efficacy trial results are a few years away, but we’re now at a time where advocacy roles are becoming clearer and clearer. VARG members left the meeting together with a new sense of priorities and actions. Watch this space!

Reflection on bNAbs and Broadening the Toolbox
Josh Agee is the PrEP Coordinator at My Brother’s Keeper in Mississippi where he educates individuals about PrEP, assess their risk of HIV and navigates insurance plans for PrEP users. He is currently a Fellow at the Black AIDS Institute’s African American HIV University.
#CROI2016 was truly an amazing experience for me. I had the chance to learn about new scientific advancement and new tools that could expand the prevention options for my community. The new treatment and prevention strategies are exciting and offer a level of promise that my community is looking for since the current options aren’t doing enough for us.
Sometimes I reflect on history and where this epidemic has been and where it might be going. I think about the things that we once thought were beyond our grasp but now seem within our reach. I think how we’ve progressed from AZT to PrEP to potentially using broadly neutralizing antibodies (bNAbs) for prevention. Researchers first identified an HIV bNAb in 2009 from a person living with HIV. Subsequently, bNAbs were proven to be highly effective in neutralizing HIV in vitro in the lab and were able to neutralize over 90 percent of HIV strains. Science has given us the promise that this could be a new strategy, and we now have begun moving the testing of bNAbs out of the labs and into clinical trials.
At the conference it was discussed, as is the case of HIV treatment, which uses several classes of antiretrovirals per regimen, that a combination of antibodies might also be effective. These monoclonal bNAbs might be more efficient combined with other monoclonal bNAbs to increase their coverage of known HIV strains. The more, the merrier might be the way to go in this strategy. It is time to see if it is something that shows promise and might be our next big breakthrough. The only way to know if this will be an effective strategy is to test this in a real world setting. Future studies with bNAbs will include administering them to populations that are at high risk for HIV acquisition. This particular research stood out to me. It is a different approach that sparked my curiosity to see where this research might take the field.
The call for needing another option could not have been clearer than when the CDC made its announcement about lifetime risk for individuals. With the CDC’s release that 1 in 2 black MSM are projected to acquire HIV in their lifetime, it is imperative that we broaden our prevention toolbox and make it accessible to the community. These staggering numbers have also prompted me to take more action in my community as I realize the state of our emergency. I plan to do more innovative community outreach and educate our community on HIV treatment and prevention. While keeping a close eye on options and making sure my community is aware that help is on the way. And more options to meet their needs are coming.
