Community Recommendations for Clinical Research Involving Antiretroviral Treatment Interruptions in Adults
November 14, 2018
– The research effort to develop a cure for HIV infection includes clinical studies in which people with HIV are asked to temporarily interrupt antiretroviral therapy. Analytical treatment interruptions (ATIs), as they are called, go against the current standard of care and may pose risks. TAG has generated an updated set of community recommendations on the use of ATIs in research, with the aim of contributing to the discussion regarding maximizing safety and minimizing risk for participants.

Toward Comprehensive HIV Prevention Service Delivery in the United States: An Action Plan
June 24, 2015 – An objective of the National HIV/AIDS Strategy (NHAS), released by the White House in July 2010, is to lower the annual number of new infections in the United States by 25 percent by the end of 2015. Yet it is unclear if we will succeed in meeting this arguably unambitious target: 36,400 estimated new infections in 2015, compared with the 48,600 new infections estimated for the baseline year of 2006.

The Immune System, HIV, and Aging
June 3, 2013 – Little more than a decade ago, it was almost inconceivable that the issue of aging with HIV infection would emerge as an important concern. But it has now become clear that combination antiretroviral therapy (ART) can suppress virus replication for many years—likely for life—in most people who can access the drugs, and the opportunistic infections that were once the primary causes of illness have largely evanesced everywhere treatment is available. Morbidity and mortality from HIV infection has plummeted, and the survival of HIV-positive individuals is edging ever closer to that of comparable HIV-negative people. With the specter of AIDS having finally been chased from the near horizon, attention has turned to health problems that may lie further down the road.

Revitalizing the U.S. National HIV/AIDS Strategy

AIDS Research: Broad Health and Economic Benefits
July 2011 – Investments in health research at the National Institutes of Health (NIH) have paid enormous dividends in the health and well-being of people in the U.S. and around the world. HIV and AIDS research supported by NIH has yielded important recent advances and holds great promise for significantly reducing HIV infection rates and providing more effective treatments for people living with HIV/AIDS.

An Exploratory Analysis of HIV Treatment Research and Development Investments in 2009
July 2011 – The HIV treatment research landscape is changing. Thanks to recent treatment scale-up and prevention science breakthroughs and the new global treatment target of 15 million by 2015, there is real momentum to bring the epidemic under control and ultimately end it. To capitalize on these scientific gains, continued investment and innovation are necessary to prevent new infections, to ensure people currently on treatment are able to continue, and to scale up treatment to reach all those who will benefit from earlier initiation of antiretroviral therapy. This report from TAG, UNAIDS, and the AIDS Vaccine Advocacy Coalition documents $2.46 billion in HIV-related research investments.

Clinical Trials for People with Suboptimal Immune Reconstitution Despite HIV Suppression
June 2011 – Some individuals who initiate antiretroviral therapy (ART) experience limited recovery of CD4 T cell numbers despite suppression of HIV viral load to undetectable levels. The most common risk factors for this type of discordant response to ART are low CD4 T cell count at the time of starting and older age. Individuals in this situation still experience a benefit from ART in terms of a greatly reduced risk of opportunistic infections, illness and death, but their risk of these outcomes is higher than among people with greater CD4 T cells gains. For this reason, a number of clinical trials are investigating approaches that might boost CD4 T cell recovery in individuals whose CD4 T cell counts remain relatively low despite viral load suppression. The purpose of this page is to provide a resource listing of these clinical trials, which will be updated on an ongoing basis.

Letter to Dr. Fauci to Support HIV and Aging Research
September 20, 2010 – The many complications and comorbidities faced by the aging population of HIV positive people in the United States constitute a rapidly growing medical crisis that has been woefully neglected by U.S. research efforts. According to the Centers for Disease Control, more than half of all HIV-positive Americans will be over the age of 50 by or before the year 2015. Although increasing evidence points to an earlier onset of age related conditions in people living with HIV little is known about pathogenesis, or proper methods to screen for, prevent and manage these conditions, or anticipate the infrastructure needed to deliver care and treatment for people suffering from these conditions.

Starting HAART: When to Take the First Step?

July 20, 2010 – Recent guidelines are all recommending that HIV treatment be started at a higher CD4 count because of issues such as the ongoing damage caused by HIV itself, and prevention of transmission. Issues in long-term treatment, such as potential side effects, the development of resistance, the cost and sustainability of programmes in resource-poor settings, are some of the potential problems for such a strategy. This session discussed the pros and cons of early initiation and highlighted areas of controversy and agreement.

TAG Featured in POZ Magazine
April 1, 2010 – Mark Harrington, founding member and executive director of Treatment Action Group (TAG), a giant in the world of HIV/AIDS treatment and advocacy, can boast about many accomplishments: his paradigm-shifting work on the Treatment and Data committee of the AIDS Coalition to Unleash Power (ACT UP), 18 years of continued achievements at TAG, countless scientific articles and speaking engagements, membership on various U.N. advisory committees, even a MacArthur “Genius” grant in 1997.

Issue Brief: A Sound Investment: The Multiplier Effect of AIDS Research
March 2010 – Investments in health research at the National Institutes of Health (NIH) have paid enormous dividends in the health and well-being of people in the U.S. and around the world. HIV and AIDS research supported by NIH has saved and improved the lives of millions and holds great promise for significantly reducing HIV infection rates and providing more effective treatments for those living with HIV/AIDS. Yet years of erratic funding levels for NIH have undermined our nation’s leadership in health research and our scientists’ ability to take advantage of the expand-ing opportunities to advance healthcare. The race to find better treatments and cures for cancer, heart disease, AIDS, and other diseases—and to control global epidemics such as AIDS, tuberculosis, and malaria—depends on robust long-term investment in health research at NIH.

TAG Mourns the Loss of Dennis deLeon
New York, December 14, 2009 – Treatment Action Group (TAG), the New York-based AIDS research and policy think tank, issued this statement today upon the death of Dennis deLeon, long-time Executive Director of the Latino AIDS Commission and former New York City Commissioner of Human Rights.

PRESIDENT OBAMA’S WORLD AIDS DAY REPORT CARD: EMERGENCY COURSE CORRECTION REQUIRED

December 1, 2009, marks President Obama’s first World AIDS Day in the White House and the first World AIDS Day for the newly elected Congress. The time is right for a frank assessment of his first year in the fight against global AIDS as President. This analysis focuses on the funding and policy decisions the Administration has made since taking office in January 2009, and assesses the human impact of those decisions.

The Future of Global Health: Ingredients for a Bold & Effective U.S. Initiative
October 2009 – Major accomplishments in global health over the last decade demonstrate that adequately resourced programs, focused on achieving specific results, can improve health outcomes for millions and support economic progress. They also show that distinct public health challenges are closely interconnected and that a comprehensive and integrated strategy is needed to ensure that ambitious health goals are met.

HIV, Tuberculosis, and Viral Hepatitis: Drugs, Diagnostics, Vaccines, and Microbicides in Development

July 2009 -–TAG’s annual Pipeline Reportsurveys the developments in medicines and diagnostics most likely to improve the lives of people living with HIV, viral hepatitis, and tuberculosis within the next few years. But in spotlighting what is in the pipeline, the report also identifies critical gaps where research is falling short of the need for better tools to manage these diseases.

Workshop Report: Studying the Impact of Genetic Variation on the Host Response to HIV
July 10, 2009 – On January 8, the Office of AIDS Research convened a two-day workshop to discuss genome-wide association scan (GWAS) studies in HIV infection. GWAS involve studying known variations in the human genetic code (called single nucleotide polymorphisms or SNPs) to find out if these variants impact an outcome of interest, such as the rate of disease progression in HIV-infected individuals. The overall goal of the workshop was to prioritize which facets of HIV infection should be investigated using the GWAS approach, as in addition to evaluating outcomes involving disease progression there are many other possibilities, such as looking for associations with resistance to HIV infection among individuals who remain seronegative despite repeated exposures to the virus. The workshop also discussed key issues related to the conduct of GWAS studies, such as the availability of appropriate cohorts and control groups, and the question of whether potential cohorts have appropriate samples and informed consent.

Flat-Lined: How Flat NIH Funding Undermines Research on HIV, Tuberculosis, and Viral Hepatitis
May 2009 – The goal of this funding analysis is to provide a comprehensive picture of the current state of U.S. National Institutes of Health (NIH) research investment in HIV/AIDS and three of its most common coinfections—hepatitis B virus (HBV), hepatitis C virus (HCV), and tuberculosis (TB)—after five years of flat funding at the NIH (2004– 2009).

TAG Calls on Obama Administration to Revitalize the World's Fight Against HIV and AIDS
April 27, 2009 – Treatment Action Group (TAG), the nation’s only organization focused exclusively on fighting for better treatments, a cure, and a vaccine for AIDS, today welcomed the Obama administration’s nomination of Dr. Eric Goosby as the next Global AIDS Coordinator in the State Department, which administers the President’s Emergency Plan for AIDS Relief (PEPFAR), the world’s largest international HIV/AIDS prevention and treatment program.

Letter to NIAID Director Anthony Fauci Opposing the HVTN 505 Vaccine Trial
April 7, 2009 – TAG has previously expressed opposition to the PAVE100A vaccine trial involving the Vaccine Research Center’s DNA and Ad5 candidate(i). With the recent presentation by Dan Barouch of new macaque challenge data involving a DNA/adenovirus prime-boost regimen at the 2009 Keystone meeting(ii), we now must vociferously oppose the proposed descendant of PAVE100A, the HVTN 505 trial.

HIV Cure Research Fact Sheet
December 2014 – Combination antiretroviral therapy (ART) is a highly effective treatment for HIV infection, preventing progression of the disease in the vast majority of recipients. When ART is accessible and started early in the course of infection, the lifespan of HIV-positive people is typically very close to that of comparable HIV-negative people. But ART can have toxicities, is often costly, and requires strict daily pill taking that can lessen quality of life. Because of the limitations of ART, a cure for HIV infection remains a vital goal for research.

TAGline 2013 Fall – Over the past several years, there has been a welcome invigoration of the research effort to cure HIV infection. The mainstream media has picked up on this development, and stories about putative or possible cures are appearing more frequently than in the past. Contrary to the impression conveyed by some of these stories, a cure is not likely to announce itself by leaping from a scientist’s test tube waving a flag of victory. To prove their worth, potential curative strategies—whether based on a single approach or a combination—will need to be evaluated in human trials.

With the specter of AIDS having finally been chased from the near horizon, attention has turned to health problems that may lie further down the road.
 
TAGline 2013 Spring - A subset of people on antiretroviral therapy (ART) experience limited or no recovery of CD4 T-cell counts despite achieving and maintaining undetectable viral loads. Various terms have been used to describe this phenomenon, with the most common being “immunological nonresponders” (INRs). Many studies have documented that INRs face an increased risk of illness and death compared with people with more robust CD4 T-cell gains. Yet there are no approved therapies to improve immune reconstitution, and clinical trials of potential candidates remain few and far between.
 
TAGline 2012 Fall – At the recent International AIDS Conference in Washington, D.C. (AIDS 2012), the research effort to develop a cure for HIV infection attained a higher profile than it ever has in the past. At a press conference on July 19, the International AIDS Society (IAS) officially launched its Global Strategy “Towards an HIV Cure,” in conjunction with a two-day symposium that immediately preceded the main conference. The IAS strategy is chaired by Françoise Barré-Sinoussi and Steven Deeks and involves a multiplicity of stakeholders, including TAG. Details are available free online in a document titled “Full Recommendations, 1st Edition, July 2012.” A shorter summary and commentary have been published in the journals Nature Reviews Immunology and Nature, respectively. In essence, the strategy is a scientific review of the obstacles to curing HIV (as they are currently perceived) and possible approaches to overcoming them. Among the goals is to enhance collaboration among stakeholders and attract new sources of funding to support cure research.

The Odyssey of Therapeutic Vaccines for HIV
TAGline 2012 Spring – In the earliest days after the discovery of HIV in the mid-1980s, uncertainty reigned regarding how the immune system responded to the virus. Initially, it was thought that the time between HIV infection and the development of severe immuno- deficiency and disease represented a period of viral inactivity or latency. In this context, it seemed logical to propose that perhaps vaccination could be used to bolster immune response to HIV and thus delay or even prevent the development of illness. But the first efforts toward this goal quickly mired therapeutic vaccine research in controversy, casting an initial pall across the field that was compounded by the failure of any candidate to show significant efficacy. Additionally, the scientific rationale for the approach evolved as more was learned about the pathogenesis of HIV infection and the types of immune responses that may be effective—and ineffective—at controlling the virus. After a period in which enthusiasm regarding the prospects for therapeutic vaccines waned, the recent resurgence in interest in research aiming to cure HIV infection has offered new reasons to pursue their development.
 
Report and Commentary from the Fifth International Workshop on HIV Persistence During Therapy
February 2012 – Inaugurated in 2003, the biannual International Workshop on HIV Persistence during Therapy (aka “the persistence workshop”) is the brainchild of researcher Alain Lafeuillade. The meeting presaged the recent explosion of interest in pursuing a cure for HIV infection, a pursuit many had considered quixotic until the case of Timothy Brown came to light in 2008. As has been extensively documented, Brown’s apparent cure resulted from a debilitating odyssey of treatments required for the grim diagnosis of acute myelogenous leukemia, enhanced with a mix of insight and good fortune on the part of his doctor Gero Hütter, who was able to provide a stem cell transplant from a donor lacking the major HIV co-receptor CCR5. The sea change wrought by this fortuitous “proof of concept” was much in evidence at the 2011 persistence workshop this past December; the tentative forays into basic science that were once emblematic of the field are now mixed together with more ambitious plans for advancing ideas into the clinic. Perhaps most strikingly, two large pharmaceutical companies—Gilead and Janssen/Tibotec—described their use of industrial scale screening to search for compounds that are active against latent HIV. This represents an unprecedented expansion of efforts once confined to under-resourced academic labs.
 
HIV Cure-Related Research Workshop Report
October 2011 – The meeting, sponsored by the AIDS Policy Project, amfAR, Project Inform, and TAG, featured an overview of HIV latency, persistence, and eradication research; lessons from past clinical trials; a review of current or impending trials; and a full discussion of issues including trial design, appropriate markers and endpoints, and development of better assays. Participants heard a presentation on the ethics of clinical trials and discussed the federal regulatory process and how best to engage the several branches of the U.S. Food and Drug Administration (FDA) in a coordinated and collaborative way to work together to ensure that cure-related clinical trials proceed expeditiously, ethically, and safely.
 
Cure Research Momentum Accelerates
TAGline 2011 Fall – The research effort to discover a cure for HIV infection continues to gain momentum, with several important developments having occurred since the last issue of TAGline.

Tallying the TB vaccines in Clinical Trials
July 2011 – The relatively small community of researchers, policymakers and advocates involved in the search for an effective TB vaccine met in Tallinn, Estonia in September, 2010 to assess the state of the field and discuss the path forward. The sense of urgency driving this research has recently been underscored in the new Global Plan to Stop TB 2011-2015, which explicitly states that without a new vaccine effective against all forms of TB, the goal of eliminating TB as a public health threat by 2050 will not be met. As described by Claire Wingfield in TAG’s annual pipeline report, TB vaccine development has long languished despite the desperate global need, but there are now encouraging signs of progress. On the second day of the Global TB Vaccines Forum, researchers offered summaries of where their candidates stand on the developmental pathway.
 
Vaccine Breakthrough Comes with Caveats
TAGline 2011 Summer - One of the main sources of pessimism about prospects for an effective HIV vaccine has been the generally poor results obtained in animal models. To date, only a live attenuated SIV (simian immunodefiency virus) vaccine has demonstrated significant efficacy against these challenge viruses, and this approach is too dangerous to be adapted for use in humans.
 
Clinical Trials Will Play a Vital Role in Charting the Path to an HIV Cure
TAGline 2011 Summer –To build the knowledge necessary to develop a safe and broadly accessible curative therapy, clinical trials of approaches that may be able to deplete HIV from the body or contribute to drug-free control of the virus are being launched.
 
Microbicide Field Wrestles with the Implications of Success—An Update
TAGline 2011 Winter – On October 25, 2010, the nonprofit microbicide research organization CONRAD announced that the U.S. Food and Drug Administration (FDA) would consider the Vaginal and Oral Interventions to Control the Epidemic (VOICE) trial as a confirmatory trial to the CAPRISA 004 results.
 
Reinvigorating the Search for a Cure
TAGline 2010 Fall – The International AIDS Society (IAS) held a workshop titled “Towards a Cure: HIV Reservoirs and Strategies to Control Them.” The workshop was a high-profile illustration of the reinvigoration of the research effort toward curing HIV infection.
 
Microbicide Field Wrestles With the Implications of Success

Letter to Dr. Fauci to Support HIV and Aging Research
September 20, 2010 – The many complications and comorbidities faced by the aging population of HIV positive people in the United States constitute a rapidly growing medical crisis that has been woefully neglected by U.S. research efforts. According to the Centers for Disease Control, more than half of all HIV-positive Americans will be over the age of 50 by or before the year 2015. Although increasing evidence points to an earlier onset of age related conditions in people living with HIV little is known about pathogenesis, or proper methods to screen for, prevent and manage these conditions, or anticipate the infrastructure needed to deliver care and treatment for people suffering from these conditions.
 
Inflammatory Debate Over When to Start
TAGline 2010 Summer – Ever since the first anti-HIV drug was approved for prescription, there has been debate and controversy regarding when an HIV-positive person should start antiretroviral therapy (ART). For hundreds of thousands of HIV-positive people diagnosed at higher CD4 counts, this life-altering treatment decision has been fraught with uncertainty due to lack of the most reliable, rigorous evidence -- that derived from well-designed, controlled, randomized clinical trials.
 
NIAID Workshop: Elimination of HIV Reservoirs
TAGline 2010 Winter – On Friday, January 15, the National Institutes of Allergy & Infectious Diseases (NIAID) sponsored a scientific workshop entitled “The Next Challenge: Elimination of HIV Reservoirs.” The event took place during the Keystone conference on HIV pathogenesis in Santa Fe, New Mexico. The focus of the agenda was on curing HIV infection, a goal once thought far-fetched but recently made to seem more attainable by a case of apparent HIV eradication, described at the workshop by Jeffrey Laurence in a talk entitled: “Proving the Concept: The First Well-Documented Functional, and Probably Complete, Case of HIV Eradication.”

July 2008 – Treatment Action Group’s annual pipeline report is a review of medical technologies that stand a good chance of benefiting people with HIV within the next few years. It also covers those that may take longer to develop but represent innovation within the field.
 
TAG's Response to NIAID "Request for Information" on Priorities in Basic HIV Vaccine Research
June 4, 2008 – It is of great concern to TAG that many of our recommendations echo many of those made by TAG eight years ago, which in turn echoed those of the Levine Report almost four years prior to that. Given this observation, we hope that NIAID can understand why we greet this undoubtedly well-intentioned RFI with a certain amount of skepticism and cynicism.
 
PAVE Gives Pause: Position Statement on the Proposed PAVE100A Vaccine Trial
May 30, 2008 – The failure of Merck's adenovirus serotype 5 (Ad5)-based HIV vaccine to protect against infection or reduce post-infection viral load, combined with the evidence of potentially enhanced susceptibility to HIV acquisition among a subset of trial participants, has inevitably cast a cloud across the Ad5 candidate slated for use in the proposed PAVE100A Phase IIb efficacy trial. TAG recognizes and appreciates the work and commitment of researchers at NIH's Vaccine Research Center (VRC) who have developed the DNA and Ad5 HIV vaccine constructs, and their colleagues involved in PAVE100 who have collaborated in an effort to redesign the trial to ensure safety in the light of the data that emerged from the Merck vaccine trial (STEP/HVTN 502, hereafter referred to as STEP).
 
STEP Vaccine Trial Halted
New York, NY, September 24, 2007 – The Treatment Action Group (TAG) today issued the following statement about the discontinuation of the STEP study, an HIV vaccine efficacy trial conducted by Merck Research Laboratories and the HIV Vaccine Trials Network (HVTN)

May 2007 – Anyone who follows HIV research is familiar with how a new potential therapeutic target can suddenly appear in the scientific literature, generating much excitement and hype, only to subsequently shuffle quietly from the scene having failed to deliver on its supposed promise. At first blush, the ominously named receptor called “program death-1” (PD-1) seems like it might fit the profile of such targets-de-jour. The role of PD-1 in shutting down virus-specific T cell responses was first described in a Nature paper in January of 2006, by researchers using a mouse model of chronic viral infection. Over the summer, three separate papers (with a commentary accompanying each) trumpeted data describing the high levels of expression of PD-1 on HIV-specific T cells, suggesting that targeting this receptor might be a way of boosting antiretroviral immunity in people with HIV. It’s legitimate to wonder if the PD-1 palaver is justified, or if the hype has leapt ahead of the science.
 
Palm Project Interview Series: Steven Deeks
February 8, 2007 - Steven G. Deeks, MD is a highly respected clinician and scientist whose work encompasses both clinical care and research into the pathogenesis of HIV infection. Deeks became widely known among treatment activists for his work on individuals with multi-drug resistant HIV who remain clinically and immunologically healthy despite the fact that their antiretroviral therapies fail to fully control HIV replication. Deeks is now involved in many different projects and collaborations but maintains a particular focus on translational research, which aims to translate advances in basic science into clinically relevant therapies and treatment strategies.
 
Palm Project Interview Series: Douglas Nixon
February 8, 2007 – Douglas Nixon, M.D., Ph.D. is a renowned cellular immunologist who has been working in the HIV/AIDS field since the late 1980s. Nixon's first published HIV research paper, which came out in Nature in 1988, involved identifying CD8 T cell responses against the virus. At that time, Nixon was working with Andrew McMichael's immunology group at Oxford in the UK but he subsequently moved to the US, first working at the Aaron Diamond AIDS Research Center before establishing his laboratory at the Gladstone Institute, University of California at San Francisco (UCSF).
 
Palm Project Interview Series: Barbara Shacklett
February 8, 2007 – Barbara Shacklett began studying HIV in the late 1980s and has become a highly respected expert in the under-studied area of mucosal immunity. Shacklett’s laboratory at UC Davis has recently published novel findings regarding the role of mucosal immune responses in individuals who control HIV replication in the absence of therapy. Barbara Shacklett generously took time out to discuss her research with TAG’s BSVP coordinator, Richard Jefferys.
