What side effects are associated with this type of intervention?

Common treatments for HIV/AIDS, including antiretroviral therapies and monoclonal antibodies like VRC01.23LS, can have various side effects. Antiretroviral drugs often cause mild to moderate side effects such as headache, fatigue, and gastrointestinal issues like diarrhea. Severe side effects can include liver toxicity, hypersensitivity reactions, and central nervous system effects. Monoclonal antibodies, while generally well-tolerated, may cause infusion-related reactions, including fever, chills, and rash. Monitoring and managing these side effects are crucial for the effective long-term treatment of HIV/AIDS.

What prior FDA approvals exist?

The FDA has approved several treatments for HIV/AIDS, primarily focusing on antiretroviral therapies (ART) that inhibit various stages of the HIV life cycle. These include nucleoside reverse transcriptase inhibitors (NRTIs), non-nucleoside reverse transcriptase inhibitors (NNRTIs), protease inhibitors (PIs), integrase strand transfer inhibitors (INSTIs), and entry inhibitors. While VRC01.23LS is an antibody that blocks HIV-like viruses, similar antibody-based treatments, such as ibalizumab-uiyk, have been approved. Ibalizumab-uiyk is a monoclonal antibody that binds to the CD4 receptor on T-cells, preventing HIV from entering the cells. This represents a newer class of treatments aimed at providing additional options for patients with multidrug-resistant HIV.

What other types of research exist?

Promising alternatives to VRC01.23LS for HIV/AIDS treatment in 2024 include: 1) Broadly neutralizing antibodies (bNAbs) like 3BNC117 and 10-1074, which have shown potential in clinical trials. 2) Long-acting injectable antiretrovirals such as cabotegravir and rilpivirine, which offer extended dosing intervals. 3) Lenacapavir, a novel capsid inhibitor with a long half-life, providing a new mechanism of action against HIV. 4) Potential vaccines in advanced stages of development, such as the mosaic-based vaccine candidates aiming to provide broad protection against diverse HIV strains.

Summary

This trial tests VRC01.23LS, a special protein designed to block HIV from infecting cells. It targets healthy adults aged 18 to 60 to ensure safety in people without other health issues. The antibody works by sticking to the virus and preventing it from entering human cells. VRC01 has been previously tested for its ability to prevent and treat HIV-1 infection.

Who is the study for?

Healthy adults aged 18 to 60 who are willing to have blood samples stored and used for research, can provide proof of identity, and agree to clinical follow-up. Women must use birth control and have a negative pregnancy test. Excluded are those with certain medical conditions, severe allergies, or recent receipt of other investigational products.

What is being tested?

The trial is testing the safety of VRC01.23LS, an antibody that may prevent HIV infection. Participants will receive either one dose or three doses over several weeks via IV or subcutaneous injection in different body parts and will be monitored closely after administration.

What are the potential side effects?

Potential side effects aren't detailed but monitoring includes checking temperature daily for a week post-injection and measuring any redness, swelling, or bruising at the injection site which suggests local reactions could be expected.

Other Research

Common treatments for HIV/AIDS include antiretroviral therapies (ART) such as reverse transcriptase inhibitors, protease inhibitors, integrase inhibitors, and entry inhibitors. These drugs work by targeting different stages of the HIV life cycle: reverse transcriptase inhibitors block the conversion of viral RNA to DNA, protease inhibitors prevent the maturation of viral proteins, integrase inhibitors stop the integration of viral DNA into the host genome, and entry inhibitors prevent the virus from entering host cells. VRC01.23LS, an investigational antibody, works by binding to the HIV envelope protein, blocking the virus from attaching to and entering host cells. This is significant for HIV/AIDS patients as it offers a potential new method to prevent infection, complementing existing ART by targeting the virus before it can infect cells.
