Introducing Implementation and Access Resources on PrEP Watch

Daily oral PrEP is moving from an idea to an offering in more countries and communities every day. And in the places where it isn’t being offered, demand is growing!

To help advocates track implementation on the ground in detail, AVAC has developed a new section of PrEP Watch (a clearinghouse of information on PrEP science, research, cost, access and advocacy) focused specifically on implementation efforts underway.

On the Implementation Initiatives page, you can find information about some of the different initiatives funding PrEP implementation in sub-Saharan Africa, including the USAID-supported OPTIONS Consortium and the PEPFAR DREAMS Initiative. Information about funder-defined initiatives can help advocates understand who’s who and what’s planned—and to follow the money!

You can also learn about the full spectrum of work happening at country level in Kenya, South Africa and Zimbabwe. As PrEP is rolled out in additional countries, more case studies will be added.

PrEP Watch will continue to grow as PrEP introduction and rollout moves forward and as new efforts and initiatives are started.

Antibody Research Advances to Prevention Efficacy Trial(s): An Advocates’ Perspective

This week the NIH-funded HIV Vaccine Trials Network (HVTN) and HIV Prevention Trials Network (HPTN) announced the launch of the HVTN 704/HPTN 085 trial, also known as “AMP” (Antibody-Mediated Prevention). The Phase IIb trial is designed to measure the safety and effectiveness of an intravenous infusion of the broadly neutralizing antibody VRC01 for HIV prevention. The infusion will be delivered to participants every eight weeks over the course of a year and a half (participants are also followed for 20 weeks after their last infusion).

AMP consists of two parallel trials conducted collaboratively by the the HVTN and HPTN. The trial that just initiated (HVTN 704/HPTN 085) has 24 sites across Brazil, Peru and the US and plans to recruit 2,700 men and transgender people who have sex with men. The other study, HVTN 703/HPTN 081, will be initiated later this year and will enroll 1,500 women at 15 sites across Botswana, Kenya, Malawi, Mozambique, South Africa, Tanzania and Zimbabwe.

For the past several years, scientists have been working with potent antibodies that neutralize many different strains of HIV. These broadly neutralizing antibodies, or bNAbs, include VRC01. Antibodies are substances made by the immune system; these bNAbs have been isolated from people living with HIV. Researchers have purified the bNAbs and modified them to make them even more effective against HIV. The antibodies in trials like AMP are delivered via infusion—meaning intravenous administration. The approach of delivering an immune defense directly is called passive immunization, and it stands in contrast to vaccination or immunizations that teach the body how to mount an immune defense itself, via a vaccine. In the AMP trial study visits are expected to take approximately 90 minutes and participants are scheduled to come to the clinic every eight weeks.

Many scientists in the field say that the point of bNAb trials isn’t to identify a new strategy for widespread use. Instead, a positive result could lead to more focused vaccine development efforts. Other researchers say that more potent antibodies that could protect in smaller, more easily-administered doses, could perhaps make it to market one day. For this to happen, all agree that the dosage (the amount delivered to a person) would need to come down from where it is in the AMP trial, and the half-life (a measure of the time that protective levels of antibody stay in the blood) would need to go up.

The AMP trials will contribute significantly to the field’s understanding of how to fight HIV. AVAC and other advocates have urged that the trial sponsors and implementers ensure consistency in the messaging about and expectations for VRC01—especially given that other, more potent antibodies may be ready for additional testing by the time the AMP trials are over, alone or in combination. (This is a common conundrum in research: first-in-class products break new ground but may not be the optimal choices for introduction.)

Extensive and continuous stakeholder engagement is essential to ensure that passive immunization trials and product development plans are clearly articulated.

The AMP trials are among the first prevention efficacy trials to start in the “post-PrEP-approval” era, raising an issue that’s challenging prevention stakeholders everywhere: the need to define the standard of prevention in trials to include daily oral PrEP, which is now recommended by the WHO for all people at substantial risk of HIV. People who participate in efficacy trials are, by definition, at substantial risk of acquiring HIV and therefore there is an ethical imperative to include PrEP. The question is how—and how to design trials that can answer questions about new products, even as incidence may go down due to PrEP use.

The AMP trial that launched this week has this to say about its approach to PrEP:

“Volunteers in the AMP Studies will be referred to available local programs where they may obtain the oral medication Truvada [TDF/FTC] to take daily for HIV prevention, a highly effective practice called pre-exposure prophylaxis (PrEP). Volunteers’ access to PrEP will expand as more host countries approve Truvada for PrEP and develop the infrastructure to support its use.”

The prevention standard of care is defined as, “condoms and lubricant, counseling on how to reduce behaviors that increase risk for infection, and counseling and referral for antiretrovirals to take immediately following suspected exposure to HIV (post-exposure prophylaxis).”

ACT UP New York member and long-time activist Luis Santiago responded, “Should Truvada/PrEP be more than just an ‘option’? Should it be actually provided in the studies in the control arm? Are we back to the ethical discussion of the 1990s?”

These questions, which were a key part of the prevention advocacy agenda years ago, still apply today—how does the field ensure that trials are not responsive to context but help to shape it? There is precedent for this, as the HVTN ensured access to antiretroviral therapy for individuals who seroconverted in vaccine trials before ART was widely available in Africa, and subsequently ensured access to voluntary medical male circumcision (VMMC) in its vaccine trial in South Africa before there was national policy on that strategy.

The reality of HIV prevention programming is rapidly evolving. In just the past four months, three of the AMP trial host countries (Kenya, Peru, South Africa) joined the US in approved TDF/FTC for daily oral PrEP, joining the USA in this decision. This leaves six AMP countries that have not: Botswana, Brazil, Malawi, Mozambique, Tanzania and Zimbabwe. But approval doesn’t mean access, and these countries may or may not have programs set up to which AMP participants can be easily and effectively referred. In that case, it’s up to the trial site to sort out provision of this key service.

At the end of the day, everyone is after the same thing—access to new options that can prevent HIV today and in the future, whether that’s a pill in hand for a young woman at risk today or a vaccine or antibody for the generations to come.

WHO Writes Back…Five Months Later: An update on HC-HIV advocacy

A nearly five-month long waiting game for a response from the World Health Organization (WHO) regarding advocates’ concerns about its confusing and inaccurate statement on the relationship between some forms of hormonal contraception and HIV ended on April 5. Sadly, the response starts a new waiting game, since the long-awaited letter promised action on some, though not all, of the points raised in the original letter (sent November 12, 2015), with no timeline or process described for taking that action. (Wheels may be turning, as the link to the October 2015 statement no longer goes to the full statement.)

By way of background, in October 2015, the WHO, without warning, posted a new statement on hormonal contraception and HIV on its website. The statement claimed to be a clarification of the existing, expert-reviewed guidance on the topic. However, it contained a range of inaccurate and confusing statements that contradicted or muddied the clarity of the statement it sought to simplify.

On November 12, 2015 an international coalition of organizations wrote an urgent letter to the WHO requesting immediate action on the statement. Citing the confusion that the new statement caused in terms of the mixed evidence showing that DMPA, aka Depo-Provera, impacts women’s risk of HIV, advocates asked for the statement to be taken down so that the existing note would continue to be the main point of reference for the field. The letter was sent by the International Community of Women Living with HIV Eastern Africa (ICWEA), co-convener of a civil society working group on contraception and HIV, and AVAC. (You can read the original sign-on letter here, and see a table below that outlines the requests in that letter with the WHO response).

The letter wasn’t officially acknowledged until some months later, when ICWEA wrote requesting an update. And the response did not come in until April 5. In summary, WHO agreed to:

(1) revise the statement to correctly characterize the evidence;
(2) revise the statement to specifically reference women’s right to know about the uncertainty regarding DMPA and HIV risk.

WHO stated that it will not add reference to additional prevention methods beyond male and female condoms, even though the technical guidance refers to a range of methods. This is particularly disappointing given WHO’s strong recommendation in September for the offer of oral PrEP for “all people at substantial risk of infection”.

ICWEA and AVAC will work with partners who signed on to the original response to develop a response in the coming days. Please be in touch with ideas and reactions.

Below is what we asked for and what WHO said, in detail:

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.

The Railroad: From science to delivery, freeing young black gay men from a tragic trajectory

Brandon Harrison is a New York City based HIV advocate and a graduate of 2014 class of the Black AIDS Institute’s African American HIV University. He has held positions at both Callen-Lorde and the Black Leadership Commission on AIDS, providing technical assistance and support for community engagement and new HIV prevention methods.

In February at the Conference on Retroviruses and Opportunistic Infections (CROI), the Centers for Disease Control and Prevention released new data that suggest the lifetime risk of HIV diagnoses in all Americans is one in 78. More alarming than that, the analyst estimated that one in two or 50 percent of all black gay, bisexual and other same gender loving men are projected to be diagnosed with HIV in their lifetime.

While we know this population and those of the trans-experience continue to have the highest new infection rates among all other populations, these new estimates have created a state of emergency among members and leaders of this community. This is a call for action. We must save ourselves, we can no longer sit back and watch our friends, family and community members fall victim to a new HIV diagnoses. It’s our responsibility to ensure that the black community is not without the knowledge and access to the proper prevention tools or understanding of antiretroviral medications.

Lack of education and access to healthcare, cultural trauma and stigma are all part of a vicious cycle that has caused not only HIV but other health and economic disparities to continue thriving in black communities. Researchers have worked hard to development major advances in preventing and treating HIV, but unless these discoveries are appropriately delivered and implemented among those who need them most, black communities will continue to be affected negatively, greater than our counterparts. It is ultimately our responsibility to take control of our health. As Black History Month has come to an end, I reflect on how much affliction our community has faced and overcome. HIV is just another one that we can fight.

As we continue fighting to end this epidemic among black communities, I have been honored to stand here at CROI thinking about the way the people inspire me with their breakthroughs. I reflect back on the Martin Delaney Panel Discussion, one of the early plenary sessions, that discussed the need to engage men of color in clinical research. I felt the passion and heart from this session was an answer to so many pieces about the other things that act as barriers in the lives of men of color. I look at this conference and the science coming from it and think we have to figure out how to guarantee access to this new promising research. You have to be able to engage these at-risk folks and keep them in the study because whatever strategy you develop has to work for them. I leave you with the words of Harriet Tubman, “If you hear the dogs, keep going. If you see the torches in the woods, keep going. If there’s shouting after you, keep going. Don’t ever stop. Keep going. If you want a taste of freedom, keep going.”

Testing Integration of PrEP into Prevention Services for Sex Workers in Senegal

It’s been slow and somewhat piecemeal—but around sub-Saharan Africa, countries are beginning to explore PrEP using daily oral TDF/FTC for HIV prevention for women, gay men and other men who have sex with men and other vulnerable groups. In the first of a series of visits to PrEP programs in action or soon to be underway, AVAC’s Policy Director, Kevin Fisher, visited a program underway in Senegal. Here is his update.

In October 2015, I visited a PrEP demonstration project focused on female sex workers which began earlier in the year in four suburban communities ringing Dakar. One of my hosts, Daouda Gueye, from the site explained that Senegal has a nationwide prevalence below 1 percent, but approximately one in four sex workers in Dakar are women living with HIV.

Gueye, whose serves as a project manager, said that the demonstration project will provide PrEP to female sex workers recruited through Senegalese health department clinics and hospitals. The demonstration project was fully enrolled with 273 women by November 2015. In Senegal, the official policy is that all women who exchange sex for money have to register with the Institute d’Hygiene Sociale or other government-run designated clinics where they are issued a health card and required to visit for bi-monthly checkups for STIs and HIV testing. Registered sex workers are given free condoms and, if they are positive, antiretroviral therapy. This PrEP project will include both government registered and unregistered sex workers who do not receive services.

Registered sex workers have lower HIV incidence than unregistered sex workers, according to Gueye. If the program is successful, Senegal will consider integrating PrEP into its suite of prevention services for registered sex workers, if support can be found to fund the program, said Dr. Moussa Sarr, one of the principal investigators.

Across Africa, many programs piloting PrEP for women are reaching out to sex workers. Some, especially through the PEPFAR-funded DREAMS program, are also exploring delivery to adolescent girls and young women.

These programs are happening in dialogue with policy makers, advocates and, in some cases, potential users. UNAIDS released in 2014 recommendations on community-based PrEP services for sex workers developed in consultation with sex workers from India and South Africa in November 2013 in Johannesburg. Sex workers have begun to explore the potential benefits of PrEP for HIV prevention in the US, too. One issue that is consistently raised is how to ensure that individuals at high risk get access to needed services—without stigmatizing the intervention—leading it to be seen as something that is only used by certain types of people. There are also concerns among some sex workers about PrEP not destabilizing their use of other prevention tools, such as condom negotiation.

This certainly isn’t the intention of the WHO’s Recommendation On Oral Pre- Exposure Prophylaxis Of HIV Infection released in September 2015. This document addresses both when to start antiretroviral therapy as well as the offer of PrEP to those at substantial risk. The Guideline recognizes that some people at substantial risk may fall into the categories of “key populations” (like sex workers or men who have sex with men) but that others, like young married women, may not.

This is a promising move—as long as programs for all people, including those specifically marginalized and discriminated against due to who they have sex with, are rolled out. We don’t want a world without sex work-specific PrEP programs (designed with the community as full partners), but we also don’t want a world where these are the only PrEP programs around.

By including both registered and unregistered sex workers, after consultations with both, the Senegalese demonstration project will hopefully provide insights into how to reach women who have different identities or have made different choices about formally adopting the label of “sex worker.”

The challenge in implementing PrEP will be to find those at substantial risk without sweeping in all sex workers or MSM or IDUs. The PrEP study in Senegal may provide one path.

UK NHS Punts on PrEP: Advocates call for decision reversal and wide access to PrEP

Early yesterday, long-time activist and aidsmap.com editor Gus Cairns wrote a piece in Huffington Post UK, “Where is PrEP?” highlighting the UK National Health Service’s silence around PrEP. In the piece he recapped an 18-month process by which he and myriad stakeholders worked towards a UK plan for PrEP, the impact of which could be significant in a county that is home to one of the largest HIV epidemics in western Europe. He encouraged fellow Britons to join him in a letter-writing campaign to the CEO of NHS England—#whereisprep?

Just hours later, NHS England released a statement on PrEP. Advocates were disappointed to learn that a PrEP policy would not be included in the NHS’ June decision-making process as was originally expected. The NHS statement noted that it was “not responsible for commissioning HIV prevention services” [like PrEP] but that it would work with other stakeholders on making PrEP available, including providing up to £2m over two years. These funds are expected to support PrEP for around 500 gay men at “early-implementer test sites”.

HIV groups in the UK quickly condemned the announcement and pushed for clarity on whose role it is (NHS, local authorities) to ensure that PrEP is widely available to all who need it, not a few hundred gay men.

Imagining LGBTI Youth Leadership in Africa

Stephen Chukwumah is an AVAC collaborator in Nigeria, working on biomedical HIV prevention with key populations. Here he reflects on the need for an African LGBTIQ Youth leadership movement. (This blog first appeared on Alturi).

“Imagine if we had a movement that is led by young LGBTIQ Africans addressing the issues in Africa and doing research on how homosexuality has always been in African cultures,” says Stephen Chukwumah as he addresses his frustrations with the journey towards equality. “Then, a young person would have the right to say that he or she is gay.”

Stephen Chukwumah is a regional and international human rights activist working on issues affecting lesbian, gay, bisexual, transgender, and intersex (LGBTI) youth from Nigeria, his home country, and beyond. But in terms of age, how does the international human rights community define a young person, and more specifically, a young LGBTI person? Stephen may argue that this question and the issues at stake for the community need to be primarily addressed by youth like him.

At the age of 19, Stephen began his journey as a youth activist when he moved to eastern Nigeria to help form Improved Youth Health Initiative, an organization concerned with educating key populations like LGBTI youth on issues of sexual health and rights. Stephen grew up in the city of Lagos, to the west, where he was trained as a peer educator by the Lagos state government through their National Youth AIDS Program. He quickly began to develop an understanding for the needs of LGBTI people at home and felt that LGBTI Nigerians in the eastern part of the country, particularly young people, were facing a lack of resources in support of the same type of trainings and advocacy present in Lagos and the capital city Abuja.

While Stephen got his start as an activist for sexual and reproductive health rights at the local level in Nigeria, he has used his platform and knowledge to advocate for LGBTI youth at the regional and international levels as a member of the Global Forum on Men who have Sex with Men (MSM) & HIV’s Youth Reference Group and as an International Youth Activist for Advocates for Youth. One of the most pivotal moments for youth activists in Africa happened at the 2015 Changing Faces, Changing Spaces Conference in Kenya, where Stephen was invited last-minute to sit on a panel discussing issues affecting young LGBTI people. During this panel, young LGBTI Africans decided that their community needed a formal organization that could be a collective voice on a wide-range of issues affecting their youth-centric movement.

A major discussion point during the panel was the need to “change the narrative that is happening in Africa where they are saying that young people are being influenced into homosexuality,” says Stephen. “To let them say that no, that is not the case, young people are not being influenced into homosexuality, they are just now being given the opportunities, support and the space to talk about the issues that affect them.” The African Queer Youth Initiative, the organization formed as a result of these discussions, hopes to rewrite the painful and often dangerous narrative surrounding LGBTI youth across the region.

The initiative’s advisory board members and newly engaged young activists will hold their first organizing meeting on the margins of the Pan Africa ILGA Regional Conference in May 2016. While a main goal of the meeting will be to establish an organizational structure, Stephen says that it will also act as a forum for young LGBTI Africans to express the community’s greatest adversities. “Young people are turned away from their homes because their parents reject the idea of homosexuality, or they don’t feel comfortable staying home because it affects their mental well being,” says Stephen, addressing a multitude of intersecting factors. Stephen also says that it is important to remember that these issues become magnified if a young person is largely dependent on his or her family for economic survival or is HIV positive.

In addition to issues of homelessness, Stephen expects his fellow advocates to address how LGBTI youth in Africa are dealing with a wide-spread, multi-front battle against discrimination at school and in the home, HIV/AIDS, free access to condoms and lube, and drug addiction.

An overarching challenge faced by the African Queer Youth Initiative will be to dismantle the pervasive myth within the LGBTI community that young people are not responsible and professional enough to operate successful organizations and campaigns in their home communities.

“On a regional or local level, there is a competition for the little funds that are available to LGBTIQ communities in Africa,” says Stephen. “So activists already working on these issues don’t want the youth to interfere.” Stephen believes that young people need to be supported by the rest of the LGBTI community so that the movement as a whole can work towards securing fundamental human rights in Africa.

Stephen says that there is a popular saying in Nigeria: “It’s he who wears the shoe that knows where it hurts.” The LGBTI community at large may possess the willingness to work with their younger counterparts, but they must begin to build an inclusive atmosphere that gives the up-and-coming activists the space and encouragement they need to lead their grassroots movement, he believes.

A FRESH Look at Basic HIV Cure Research

The Female Rising through Education, Support and Health cohort, or FRESH, located in the Umlazi Township outside of Durban, South Africa, is showing how basic science research can do more than just collect blood samples. Updates on work with FRESH are highlighted in other advocates’ reflections on CROI 2016.

The FRESH cohort—presented at CROI 2016—is a population of young women enrolled in a longitudinal study conducted by the Ragon Institute in Boston, MA and the University of KwaZulu-Natal in Durban South Africa. The purpose of the study is to identify young women (ages 18-23) in very early HIV infection—also known as “acute infection”—to study the innate, or primary, immune system and to address gaps in HIV prevention within this population.

In addition to biweekly clinic visits to draw blood, vaginal and cervical swabs, the women take part in an intensive training and education program to prepare them for jobs, entrepreneurship or reentry into the school system. The women attend two, three-hour classes per week over the course of 12 months. This intensive skills-building program was put in place to combat poverty in the population, a known driver of the epidemic, and help retain young women in the study.

The cohort began enrollment in 2013 and as of September 29, 2015, 699 women have been enrolled. Over 24 months 32 women were diagnosed soon after infection.

At the pre-CROI Community Cure Workshop, Zaza Mtime Ndhlovu (University of KwaZulu Natal) presented his research on HIV specific CD8 T cell responses in early infection. A subset of the cohort’s acutely infected women contributed to Dr. Ndhlovu’s research looking at T-cells directly before and after infection. Dr. Ndhlovu’s work shows that during the acute infection phase, HIV-specific CD8 cells develop very quickly and in high numbers. The number of HIV-specific CD8 T cells varies from person to person and contributes to the viral set point of the individual.

This means as soon as HIV enters the body, within the first few days, these HIV-specific CD8 cells can immediately begin fighting the virus. This is why the more HIV-specific CD8 responses an individual has the lower their viral set point. These HIV-specific CD8 T cells are prone to dying, so they don’t last long in the body.

This is significant because it offers a potential strategy toward HIV remission. If researchers can preserve these CD8 cells, either by preventing their death, by using a drug to enhance the immune system, or by priming the body to make more HIV-specific CD8 cells through a vaccine, they could potentially develop a “kill” component of a “kick and kill” curative strategy. The FRESH cohort is providing researchers with a new model of working with communities to prevent new HIV infections and conduct basic research toward a cure.
