HIV/AIDS

Fred Hutch is a longtime leader in the global fight against HIV/AIDS. Our research on prevention, treatment and potential cures includes active studies and statistical assistance to studies in countries on five continents.

We use our expertise in virology and immunology to investigate HIV at the molecular level, with the goal of identifying events that lead to infection and transmission and to understand the complex relationship between HIV and the immune system.

Patient Treatment & Care

At Fred Hutch, our interdisciplinary teams work together to prevent, diagnose and treat cancer, HIV/AIDS and other diseases. Our aim is to provide patients access to advanced treatment options while getting the best cancer care.

Selected Clinical Trials

Clincial research is an essential part of the scientific process that leads to new treatments and better care. Clinical trials can also be a way for patients to get early access to new cutting-edge therapies. Our clinical research teams are running clinical studies on HIV/AIDS and hiv-related diseases.

HIV and Relapsed, Refractory or Disseminated Malignant Neoplasms

This phase I trial studies the side effects of pembrolizumab in treating patients with human immunodeficiency virus (HIV) and malignant neoplasms that have come back (relapsed), do not respond to treatment (refractory), or have distributed over a large area in the body (disseminated).

HIV Clinical Trial

HIV Positive Hematologic Cancers

This phase II trial studies the side effects of a cord blood transplant using OTS and to see how well it works in treating patients with human immunodeficiency virus (HIV) positive hematologic (blood) cancers.

HIV/AIDS Research

Fred Hutch scientists, biostatisticians and epidemiologists study the evolutionary history of HIV and track the course of the epidemic. We analyze the results of experimental vaccines and microbicides to prevent the disease. In addition to the design and oversight of HIV vaccine clinical trials at HVTN, our researchers study mechanisms of natural protection found in a small subset of people who can suppress the virus without medication. We also search for broadly neutralizing antibodies, rare proteins that could work against multiple strains of HIV. We are testing new vaccines designed to get immune cells to produce such antibodies reliably — the holy grail of HIV vaccine research. We continue to study new technologies with the goal of curing HIV in people who are already infected.

Designing a Broadly Neutralizing Vaccine

Most HIV/AIDS vaccines fail because the immune proteins, or antibodies, that they generate zero in on specific surface features of the virus that can rapidly change their shape through genetic mutation whenever the virus makes copies of itself. These mutations allow the virus to hide from antibodies.

But some antibodies, known as broadly neutralizing antibodies, are able to block many variants of a virus. We are designing vaccines that cause the body to make this type of antibody against HIV. They target parts of the HIV surface that cannot change shape without crippling the virus. In theory, the virus cannot evade such a vaccine. Tests will show if the vaccine works. 

HIV and the Immune System

We are learning how protective antibody responses against HIV develop. For instance, infants can generate protective antibodies more quickly than adults. Work by our scientists suggests that the immune responses of infants hold insights that could help improve HIV vaccine design. 

Our researchers are also studying how HIV slips past our immune system. Using a cutting-edge approach called deep mutational scanning, our scientists have compiled a library of every possible genetic mutation that affects the proteins on the surface of HIV. Their tests are showing how the structure of each mutation affects the ability of HIV to escape antibodies. This information can help us design a more effective vaccine.

HIV Vaccines and the Microbiome

Our scientists are exploring how the microbiome — the vast community of bacteria and other foreign microbial life that inhabits our bodies — interacts with the immune system and may influence vaccine responses.

The failure of one experimental HIV vaccine may have been due to a “cross-reaction” with bacteria in the human gut. Components of the vaccine that were meant to trigger an immune response against HIV instead targeted a similar-looking feature on the cell membranes of common gut bacteria. The vaccine was apparently fooled, as if by a decoy, into reacting against the bacteria instead.

Studying HIV-Positive People Who Stay Symptom Free

Researchers led by Dr. Julie McElrath are investigating why about 1 percent of people who are living with HIV can naturally suppress HIV without medication. The goal is to find out if these “long-term nonprogressors,” or “elite controllers,” carry unknown biological mechanisms that protect them from HIV. If researchers can duplicate these mechanisms, they may be able to prevent HIV progression and improve outcomes among a much broader group of people with HIV. The studies are based at the Seattle Vaccine Trials Unit, one of more than 40 HVTN research sites around the world.

Engaging Communities to Ensure Diversity

To ensure that diverse communities are included in HIV/AIDS research and that their cultures are respected, HVTN and defeatHIV work with community advisory boards — organizations that help community members understand HIV/AIDS science and engage with our researchers in the planning and implementation of trials.

We provide our communities with workshops and ongoing educational programs on equity and anti-oppression issues. We also develop case studies on ways to increase participation in vaccine trials, reduce disparities and improve the recruitment, retention, and training of ethnic minorities.

Cell and Gene Therapy to Cure HIV

Through the defeatHIV program, we are testing ways to:

  • Genetically engineer blood cells to be resistant to HIV replication
  • Develop gene therapy techniques that mutate HIV and render it incapable of replicating in an infected person
  • Deliver synthetic proteins that stop HIV reactivation
  • Stop the proliferation of cells that sustain the HIV reservoir

HIV/AIDS Networks

HIV Vaccine Trials Network

Our researchers play key roles in several large-scale networks dedicated to the elimination of HIV/AIDS. They include the HIV Vaccine Trials Network, which is based at Fred Hutch. HVTN is the world’s largest publicly funded international collaboration conducting clinical trials of HIV vaccines, with thousands of participants joining every year.

defeatHIV

Fred Hutch hosts defeatHIV, a multi-institutional consortium focused on cell and gene therapy approaches to eliminate HIV from reservoirs of latently infected cells. HIV in these reservoirs reactivates if patients stop taking antiviral drugs.

Statistical Center for HIV/AIDS Research and Prevention

We are home to the Statistical Center for HIV/AIDS Research and Prevention, or SCHARP. SCHARP helps researchers worldwide and is staffed by experts in clinical and laboratory data management, programming and statistics.

HIV/AIDS Network Coordination

The Office of HIV/AIDS Network Coordination (HANC), based at Fred Hutch, works with HIV/AIDS Clinical Trials Networks of the U.S. National Institutes of Health (NIH) to create a more integrated, collaborative, and flexible research structure to develop safe and effective drugs, prevention strategies, and vaccines.
