4,971 Clinical Trials for Various Conditions
The purpose of this study is to evaluate the safety, tolerability, and efficacy of combination broadly neutralizing antibodies (bNAbs), to induce HIV-1 control during analytic treatment interruption (ATI).
HVTN 206/HPTN 114 is a randomized, double blind, controlled, phase 2 clinical trial to evaluate the safety, tolerability, pharmacokinetics, and neutralization of VRC07-523LS, PGT121.414.LS, and PGDM1400LS broadly neutralizing monoclonal antibodies given intravenously in adult participants without HIV. The hypothesis of the study is that the combination of VRC07-523LS and PGT121.414.LS and PGDM1400LS antibodies when administered via the intravenous (IV) route will be safe and tolerable in adult participants without HIV. The study aims to enroll 200 participants across multiple sites with an estimated total duration of participation of eighteen (18) months.
This study evaluates the safety, tolerability, and pharmacokinetics (PK) of a single dose administration of VH4527079 by subcutaneous (SC) injection or by intravenous (IV) infusion in healthy adult participants and multiple dose administration by IV infusion in healthy adult participants and in Persons with HIV (PWH).
The objective of this study is to evaluate the performance, usability, and result interpretation of the INSTI® HIV Self-Test (referred to INSTI® HIV ST) in the intended use population across the United States (US). The INSTI® HIV Self-Test is a single use in vitro test that is used as a self-test for the detection of antibodies to HIV-1 and HIV-2 in human fingerstick blood. This study is designed to evaluate INSTI® HIV ST performance in the hands of non-professionals and untrained lay users who are inexperienced in HIV blood-based self-testing. The study aims to: To evaluate the clinical performance (i.e., diagnostic sensitivity and specificity) of the INSTI® HIV Self-Test in a lay user population. To assess the user's comprehension of the INSTI® HIV ST results (e.g., interpreting positive, negative, and invalid results). To evaluate the usability of the INSTI® HIV ST and understand users' experience in performing the test.
The purpose of this study is to evaluate the safety, tolerability, and efficacy of therapeutic vaccination with chimpanzee adenovirus ChAdOx1- and poxvirus modified vaccinia Ankara (MVA)-vectored conserved mosaic T-cell vaccines in a sequential regimen with the toll-like receptor 7 (TLR7) agonist vesatolimod (VES) and two broadly neutralizing antibodies (bNAbs) compared to placebo, to induce HIV-1 control during analytic treatment interruption (ATI).
This is a multicenter controlled interventional trial. This phase 1 trial is the first study to assess 426c.Mod.Core-C4b adjuvanted with 3M-052-AF + aluminum hydroxide suspension (Alum) in people living with HIV (PLWH).
A5388 is a phase II, two-arm, randomized, double-blind, placebo-controlled study that will enroll 48 antiretroviral therapy (ART)-naïve adults with acute HIV infection (AHI) in order to determine whether: * Administration of combination HIV-specific broadly neutralizing antibody (bNAb) therapy in addition to ART during acute HIV infection (AHI) will be safe. * Participants who receive combination bNAb therapy in addition to ART during AHI will be more likely to demonstrate a delay in time to HIV-1 RNA ≥1,000 copies/mL for 4 consecutive weeks compared to participants who receive placebo plus ART. * Participants who receive combination bNAb therapy in addition to ART during AHI will demonstrate lower viral reservoirs and enhanced HIV-specific immunity compared to participants who receive placebo plus ART.
Background: People with HIV usually take a combination of 2 or more anti-HIV drugs daily to help manage their infection. Sometimes, however, HIV becomes resistant to these drugs, and the infection cannot be treated. Untreated HIV infection can make people more vulnerable to other infections as well as some cancers. Better treatments are needed for people with drug-resistant HIV. Objective: To see if a study drug (UB-421) is effective in people with drug-resistant HIV. Eligibility: People aged 18 years and older with HIV that is resistant to anti-HIV drugs. Design: Participants will be in the study for 35 weeks. Participants will have separate screening and baseline visits within 2 months of each other. They will have a physical exam with blood and urine tests both times. On the second visit, they will undergo apheresis: Blood will be drawn from a needle in one arm. The blood will pass through a machine that separates out the white blood cells. The remaining blood will be given back through a second needle in the other arm. Participants will begin receiving the study drug 1 week after their baseline visit. UB-421 is given through a tube attached to a needle placed in a vein in the arm. They will return for UB-421 treatments every week for 26 weeks. Each visit will take 3 to 6 hours. Participants will have 2 follow-up visits 4 and 8 weeks after their last treatment with UB-421. Apheresis will be repeated at 1 of these visits.
TMB-365 is a monoclonal antibody that binds to the CD4 receptor. TMB-380, aka VRC-07-523LS is a monoclonal antibody that binds to HIV. Both interfere with HIV entry. This study is designed to test various doses of the combination of the antibodies for safety and pharmacokinetics in suppressed subjects on cART. Once dosing is established based on safety and PK, the optimally dosed combinations will be assessed as maintenance therapy in HIV infected suppressed individuals discontinuing oral cART for 24 weeks.
Trimer 4571 is a vaccine designed to stimulate the development of broadly neutralizing antibodies (bnAbs) against HIV. Trimer 4571 is investigational, meaning it is not approved by the US Food and Drug Administration (FDA). There is limited human experience with the Trimer 4571 vaccine administered with aluminum hydroxide (alum) and the vaccine has not been tested in people with HIV prior to this study although it has been tested in healthy volunteers. The goal of this study is to see if Trimer 4571 is safe and well tolerated and to see if it will help the immune system produce bnAbs against HIV.
A multicenter, randomized, parallel-group, placebo-controlled, double-blind, Phase 1/2a clinical study to investigate the safety, tolerability, immunogenicity and exploratory efficacy of a vaccine regimen consisting of an Ad26.Mos4.HIV prime and a boost with Modified Vaccinia Ankara (MVA)-BN-HIV in combination with broadly neutralizing antibodies (bNAb) PGT121, PGDM1400, and VRC07-523LS in human immunodeficiency virus type 1 (HIV-1)-infected study participants on suppressive anti-retroviral therapy (ART).
This study is to evaluate antiviral activity, efficacy, safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of GSK3810109A in HIV-1 infected treatment naive adults. Participants will receive a single dose of GSK3810109A administered either intravenously (IV) or subcutaneously (SC). The study includes a screening phase, a randomized monotherapy phase and a standard of care follow-up phase.
The purpose of this study is to evaluate the safety, tolerability, and efficacy of N-803, an IL-15 superagonist, with or without combination broadly neutralizing antibodies (bNAbs), to induce HIV-1 control during analytic treatment interruption (ATI).
The proposed study is a phase 1, open label, single arm study to evaluate the safety, pharmacokinetics and antiviral activity of single intravenous infusions of 3BNC117-LS and 10-1074-LS, each monoclonal antibody (mAb) dosed at 30 mg/kg in viremic human immunodeficiency virus (HIV)-infected individuals.
This study will be conducted in two stages and will test the safety/tolerability, pharmacokinetics (how the body handles study drug) and pharmacodynamics (effects on the immune system and the virus) of the study drug ABBV-181 in Human immunodeficiency virus (HIV)-1 infected participants undergoing Antiretroviral therapy (ART) interruption.
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics, and antiviral activity of the monoclonal antibody PGT121.414.LS administered alone and in combination with VRC07-523LS via intravenous or subcutaneous infusions in healthy, HIV-uninfected adult participants.
To assess the safety of combination immune therapy in HIV-infected participants whose HIV is controlled with ART, by determining the incidence and severity of adverse events.
Background: Most people with tuberculosis (TB) feel better after starting treatment. But for some people, the opposite happens. They may feel better at first, but then suddenly get worse. This is a paradoxical reaction. Researchers want to better understand what causes this reaction and what happens after someone has it. Objective: To learn about paradoxical reactions to TB treatment. Eligibility: Adults 18 and older diagnosed with confirmed or suspected TB and currently on treatment for at least 2 weeks, with or without signs/symptoms of a paradoxical inflammatory reaction. Design: Participants will be screened with a physical exam and medical history. They will give blood and urine samples. Eligible participants will visit the NIH Clinical Center 3 times over 6 to 18 months. Each visit will take 7 hours to complete; visits may be scheduled over more than 1 day. Participants may have more visits if their TB symptoms change. Participants will give blood, urine, and sputum samples. They will have adverse event assessments. They will have 2 to 3 positron emission tomography/computed tomography (PET/CT) scans. PET/CT scans make pictures of the inside of the body. For this, participants will lie on a table that slides into a donut-shaped scanner. They will get a small amount of radioactive dye through an IV, which is a small plastic tube placed in a vein in the arm using a needle. Participants may have optional apheresis. For this, blood is taken from a needle in one arm. White blood cells are separated from the rest of the blood. The rest of the blood is returned through a needle in the other arm.
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics, and antiviral activity of combinations of monoclonal antibodies PGT121, PGDM1400, 10-1074, and VRC07-523LS administered via intravenous infusion in healthy, HIV-uninfected adults.
Many HIV-infected individuals mount a broad neutralizing serologic response 2-3 years after infection. Broadly neutralizing antibodies might play an important role in protection from acquisition of HIV infection because they can protect macaques from infection, and the presence of anti-HIV antibodies was the only positive correlate of protection in an HIV vaccine efficacy trial (RV144 trial). HIV neutralizing antibodies also have the potential to alter the course of HIV infection in humans. Therefore, these antibodies might be useful to both prevent and treat HIV-1 infection. This is a phase 1 dose escalating clinical trial to evaluate the safety, tolerability, pharmacokinetics and the antiretroviral effects of a novel bispecific monoclonal antibody 10E8.4/iMab in HIV-infected and HIV-uninfected individuals. The study will be conducted as a multi-center study at the Columbia University Medical Center in New York City and the Orlando Immunology Center in Orlando, Florida.
Background: A daily drug combination can keep human immunodeficiency virus (HIV) levels low for a long time. But if this combination antiretroviral therapy (ART) stops, HIV levels go back up. People can also develop resistance or permanent side effects. Researchers want to see if 2 new drugs can help control HIV when a person is not on ART. Objective: To see if VRC01 and 10-1074 are safe and control HIV when a person is not on ART. Eligibility: Adults 18-65 with HIV Design: All participants must agree to practice safer sex. Those who can get pregnant will have a pregnancy test every visit. Participants will be screened with: Physical exam Medicine review Blood and urine tests Some participants may need to change their HIV medicine for a brief period of time during the study. A few weeks later, participants will repeat screening tests and stop taking their HIV medicines. Interruption phase 1: Participants will have blood tests every 2 weeks, and repeat screening tests every 4 weeks. Treatment phase: Once their HIV reaches a certain level in the blood, participants will get the 2 study drugs or a salt water placebo. They will not know which they get. Each substance will be given through a thin tube in an arm vein for about 1 hour. Participants will restart their HIV medicines and repeat screening tests every 4 weeks. Interruption phase 2: Once the level of HIV in the blood becomes undetectable for 3 months, participants will again stop taking their HIV medicines and have blood tests every 2 weeks to monitor the level of HIV in the blood. Participants will restart their medicines by week 24. They will start sooner if they have certain symptoms or blood levels of HIV become too high. They will repeat most screening tests 3 times over 24 weeks.
Adult participants (18-64 years old) with HIV-1 Infection on ART with a CD4 T cell count ≥ 350 cells/mm3 and viral suppression for ≥ 24 months will be enrolled on this study. Participants will receive two series of combination therapy consisting of one (1) intravenous (IV) dose of VRC-HIVMAB075-00-AB (VRC07-523LS) followed by 10 oral (PO) doses of Vorinostat (VOR) taken every 72 hours. Each series will last approximately 1 month and the two series will be separated by at least one month. Combination ART is maintained throughout the study. Participants will be on this study for approximately 28 weeks (or about 7 months). The purpose of this study is to: * Evaluate the safety of two series of a VRC07-523LS infusion followed by multiple oral doses of VOR * Determine if combining VRC07-523LS and VOR can have an impact on non-active HIV virus.
The purpose of this study was to evaluate the safety and immunotherapeutic activity of an anti-PD-1 antibody (cemiplimab) in participants with HIV-1 on suppressive combination antiretroviral therapy (cART).
Background: HIV stands for human immunodeficiency virus, which is the virus that causes AIDS. There is currently no licensed vaccine to prevent HIV infection. Researchers want to test a vaccine called Trimer 4571 for the first time. It was made at the National Institutes of Health (NIH) and contains no HIV. The vaccine is mixed with a substance called alum and injected in the arm. Alum is included to boost the body's immune response to the vaccine. It has been used in licensed vaccines for over 60 years and has been found to be safe. Objectives: To see if the vaccine Trimer 4571 is safe, well-tolerated, and to study immune responses to it. Eligibility: Healthy adults ages 18-50 years Design: Participants were screened with a physical exam and blood tests. They agreed to not become pregnant and to avoid behavior that would put them at high-risk for HIV infection during the study. Participants had about 15 study visits over about 9 months. The first 6 participants received a low dose of the vaccine mixed with alum. Once the low dose was deemed safe, 10 new participants were allocated to receive a higher dose. All participants were randomly assigned to get the vaccine by injection in a muscle or under the skin. All participants received a total of 3 vaccine injections over 20 weeks. Each visit where participants received the vaccine lasted about 5 hours. Participants were watched after each injection. Participants who were able to get pregnant would have a pregnancy test before each injection. Participants received a thermometer and recorded their temperature and symptoms every day for 1 week after each injection. The injection site was checked for redness, swelling, or bruising. At follow-up visits, participants had blood drawn and checked for health changes or problems. Follow up visits lasted about 1-2 hours.
This is a single center exploratory imaging study involving one intravenous microdose of 89Zr-DFO-VRC01 followed by whole-body PET-MR imaging in HIV infected individuals and healthy volunteers. Imaging data will be obtained from up to four static PE-MR images in order to determine dosimetry and temporal tissue uptake/tissue distribution of 89Zr-DFO-VRC01. This is not a treatment study of the biological activity of 89Zr-DFO-VRC01 to impact HIV persistence.
This is a Phase 1/2a open label study to evaluate the safety, tolerability, pharmacokinetics and anti-viral activity of PGT121, VRC07-523LS and PGDM1400 for HIV prevention and therapy.
The purpose of this study is to evaluate the breadth and potency of HIV-1 neutralizing antibody (nAb) responses and examine the safety and tolerability of an HIV gp120 protein vaccine (AIDSVAX® B/E) in HIV-uninfected adults diagnosed with Systemic Lupus Erythematosus (SLE) who have stable disease.
This phase II trial studies the use of human papillomavirus (HPV) deoxyribonucleic acid (DNA) plasmids therapeutic vaccine VGX-3100 (VGX-3100) and electroporation in treating patients with human immunodeficiency virus (HIV)-positive high-grade anal lesions. Vaccines made from DNA may help the body build an effective immune response to kill tumor cells. Electroporation helps pores in your body's cells take in the drug to strengthen your immune system's response. Giving VGX-3100 and electroporation together may work better in treating patients with high-grade anal lesions.
This study will evaluate the safety, tolerability and innate immune mechanisms activation following administration of the combination of Pegylated Interferon alpha 2b (peg-IFN-α2b) with two broadly neutralizing antibodies (3BNC117 and 10-1074) in the setting of well-controlled HIV infection with antiretroviral treatment and a monitored analytical treatment interruption. The current proposal builds on previous experience using interferon alpha, 3BNC117 and 10-1074 alone in separate clinical trials that included a closely monitored analytical treatment interruption. The hypothesis is that the joint administration of peg-IFN-α2b with 3BNC117 and 10-1074 will be more effective than either intervention separately in suppressing HIV viremia during 8 weeks of analytical treatment interruption (Step 4) and reducing integrated HIV DNA in blood and tissue when measured during an analytical treatment interruption in patients with well-controlled HIV infection.
Background: Human immunodeficiency virus (HIV) affects the immune system. The main function of the immune system is protect you from infections and other diseases such as cancer. HIV attacks and cripples the immune system making people more susceptible to a variety of infections and cancers. Currently, the standard treatment for HIV infection is a daily administration of anti-HIV drugs. These drugs are called combination antiretroviral therapy (ART). ART is very effective at suppressing HIV, but does not cure HIV infection. ART must be taken continuously for life to be effective. ART can stop being effective if not taken correctly and can cause permanent side effects. Researchers want to see if two new products can control HIV infection without the use of ART. The products are the antibodies 3BNC117 and 10-1074. Objective: To see if 3BNC117 and 10-1074 are safe and can control HIV levels in the blood of people who are not taking ART or people who stop taking their ART during the study. . Eligibility: Adults ages 18-65 with HIV who are: * on ART and willing to stop treatment for at least 28 weeks * OR not taking ART with low levels of HIV in the blood Design: Participants will be screened with a physical exam, medical history, and blood, heart, and urine tests. Participants will get the 2 study products or salt water (placebo). A thin tube will be placed in an arm vein. Each product will be given directly into the vein for about 1 hour. To help collect blood cells to study in the laboratory, participants may have a procedure known as leukapheresis in which blood will be removed through a needle in the arm. Some of the white blood cells will be separated from the blood and used for research studies to see how 3BNC117 and 10-1074 effects HIV and the immune system. The rest of the blood will be returned to the person through another needle in the arm. Participants will have 18 study visits over 28 weeks. They will repeat some screening tests. They may have leukapheresis again. At 8 study visits, participants will get the study products or placebo. All participants will be followed for at least 24 weeks after their last dose of the study infusions. Participants who are in the Group that stops ART will be monitored closely to make sure the levels of virus in their blood do not go to high. If at any time during this the study a person develops HIV-related symptoms, or if the viral levels go up to high levels for more than 4 weeks, ART will be restarted and no further infusions of 3BNC117 and 10-1074 will be given. ...
