HIV Vaccines for HIV/AIDS
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests two new vaccines for HIV, the virus that leads to AIDS. Researchers aim to determine if these vaccines, combined with adjuvants (which boost the body's immune response), are safe and can trigger an immune reaction. Participants are divided into groups to receive different combinations and doses of these vaccines, including CD4BS CH505M5 Pr-NP1 and CH505TF chTrimer. The trial seeks volunteers in good general health, at low risk of acquiring HIV, and who have tested negative for HIV. Individuals who maintain a lifestyle that keeps them at low risk for HIV and have had no serious reactions to vaccines may find this trial suitable. As a Phase 1 trial, this research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive these new vaccines.
Do I have to stop taking my current medications for the trial?
The trial protocol does not specify if you need to stop taking your current medications. However, if you are on medications that might impair your immune response, like certain steroids, you may need to discuss this with the trial team.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that the CD4BS CH505M5 Pr-NP1 vaccine is being tested for safety in healthy individuals without HIV. Early results from other studies suggest that the vaccine helps the body produce antibodies to combat HIV. However, more information is needed to understand how well individuals tolerate this vaccine.
The CH505TF chTrimer vaccine is under study for safety in people living with HIV. These studies aim to determine if the vaccine is safe and well-tolerated. While results are still being collected, the research is promising regarding its safety.
Both vaccines are in the early stages of clinical trials, meaning they are still being tested for safety in humans. This phase is crucial for identifying any potential side effects and understanding how participants respond to the treatment.12345Why are researchers excited about this trial's treatments?
Researchers are excited about these HIV vaccine treatments because they represent a novel approach to preventing HIV/AIDS. Unlike existing antiretroviral therapies that manage the virus, these vaccines aim to prevent HIV infection by using the CD4BS CH505M5 Pr-NP1 component, which is designed to elicit a strong immune response against the virus. Some treatment groups also include innovative adjuvants like ACU-026-001-1 and 3M-052-AF, which boost the body's immune response, potentially making these vaccines more effective than traditional options. Additionally, combining these vaccine components with the CH505TF chTrimer offers a new strategy to enhance immune protection. This innovative approach could pave the way for long-lasting protection against HIV, a significant advancement over current preventive measures.
What evidence suggests that this trial's treatments could be effective for HIV/AIDS?
Research has shown that the CD4BS CH505M5 Pr-NP1 vaccine, which participants in this trial may receive, can trigger the body's immune response. In earlier human trials, this vaccine successfully initiated the creation of special antibodies that fight HIV. Similarly, the CH505TF chTrimer vaccine, another treatment option in this trial, produced strong antibodies against HIV. Early studies found that combining this vaccine with an immune-boosting ingredient led to a strong response in participants. These findings suggest that both vaccines could help the body fight HIV effectively.12567
Are You a Good Fit for This Trial?
This trial is for adults without HIV who are in good health. Participants will be part of a study testing two experimental HIV vaccines combined with different adjuvants to boost immune response. The trial excludes individuals under certain medications, those with immune system issues, or anyone with conditions that might interfere with the study.Inclusion Criteria

Trial Overview
The clinical trial is evaluating the safety and effectiveness of two HIV vaccine candidates: CD4BS CH505M5 Pr-NP1 and CH505 TF chTrimer. These are given alongside adjuvants—either Lipid Nanoparticles (LNPs) or 3M-052-AF plus Alum—to enhance immunity.
