Active clinical trials for "Acquired Immunodeficiency Syndrome"

The HIV Vaccine Trials Network (HVTN) is doing a study to test a new HIV vaccine combination. HIV is the virus that causes AIDS. 252 people are taking part in this study at multiple sites. The US National Institutes of Health (NIH) is paying for the study. The investigators are doing this study to answer several questions. Are the study vaccines safe to give to people? Are people able to take the study vaccines without becoming too uncomfortable? How do people's immune systems respond to the study vaccines? (Your immune system protects you from disease.)

The investigators propose to improve HIV prevention and care through expanding HIV testing options to include self-testing for young women, their peers and their sex partners, and by facilitating linkage to care.

A phase I/IIa, multinational, multicentric (IDIBAPS, IRSICAIXA, AARHUS, VUB, APHP), randomised, balanced by centre (to include participants from the 4 arms), open-label, controlled clinical trial. Each participant will be followed up a different time according to study arm: a minimum of 38 weeks in arm I, 31 weeks in arm II, 54 weeks in arm III and 26 weeks in the arm 4. The study duration will be 104 weeks from inclusion of the first participant. Participants will be randomised to one of the following 4 arms: Arm 1 (study): 14 participants will receive 3 vaccines of HIVARNA01.3 prime, 2 MVA-vectored vaccine boosts, 1 dose of 10-1074 antibodies and 3 doses of romidepsin Arm 2 (study): 14 participants will receive 5 vaccines of HIVARNA01.3, 1 dose of 10-1074 antibodies and 3 doses of romidepsin Arm 3 (study): 14 participants will receive 5 vaccines of personalized RNA vaccine (HIVACAR01), 1 dose of 10-1074 antibodies and 3 doses of romidepsin Arm 4 (control): 14 participants 1 dose of 10-1074 antibodies and 3 doses of romidepsin

The study will evaluate the use and preliminary impact of an mHealth app for improving sexual health outcome measures among male couples by assessing whether exposure and use of the app results in improvements in participants and couples' self-reported sexual health and prevention behaviors, beliefs, and attitudes. The study will enroll both men of the couple into a randomized controlled trial. Participants/couples randomized to the intervention will have access to the app for two months while those assigned to the waitlist group will receive and have access to the app for one month. Participants will complete surveys at baseline and at month 2.

The purpose of this research study is to determine the best way to increase screening for cervical cancer, colorectal cancer, HIV, and Hepatitis C among under screened Hispanic, Haitian and African-American individuals in Hialeah, South Dade, and Little Haiti. The investigator will compare home testing led by a community health worker (CHW) versus clinic testing guided by a CHW. Community Health Workers are people who have undergone several weeks of community outreach and health education training. During the study period the participant will continue to receive all of their regular medical care from their regular health care providers. If the participant does not have a health care provider, the Community Health Workers would be able to help in referring the participant for care at a local health care clinic located in their community.

This is a multi-center, randomized, controlled, open clinical trial. The trial will be carried out in five provinces in China. Pregnant women with HIV infection and at high risk of mother-to-child transmission of HIV will be identified. Their newborn babies who are at high risk HIV infection will be recruited and randomized into intervention and control groups. Children in intervention groups will receive ART and intensive HIV testing after birth. Children in control group will receive routine prevention of mother-to-child transmission services. All the included children will be followed up and their development and infection status will be recorded and compared.

This study is a Phase I, open-label, single dose, mass balance study in a cohort of 6 healthy adult male subjects. The study will consist of: Screening evaluations, a treatment phase, and follow-up evaluations. In the treatment phase, after an overnight fast of at least 10 hours, each subject will receive a single oral suspension dose of GSK2248761 200mg containing [14C] - GSK2248761. Following dosing, serial whole blood, plasma, urine, and fecal samples will be collected. Subjects will be required to remain in the unit until the radiocarbon excreted falls to less than or equal to 1% of the administered dose for two consecutive 24-hour collections in both urine and feces, whichever occurs first. Safety will be assessed by vital signs, 12-lead electrocardiogram (ECG), clinical laboratory tests, AE monitoring, and physical examinations as indicated.

The reduction with antiretroviral therapy (ART) of HIV RNA in blood, and HIV RNA in infected cells and in viruses associated with the follicular dendritic cell (FDC) network in lymphatic tissues, typically follows a two-phase pattern of decline. The half-life of the first-phase is about 1 day and that of the second phase is about 14 days, with comparable estimates for first-phase decay in SIV-infected rhesus macaques. While substantial evidence supports the current view that first-phase decay reflects the death of activated CD4+ T cells infected before ART was begun, the sources of viral RNA in the second phase have not as yet been conclusively established. Possible sources of viral RNA that have been invoked in mathematical models, or for which there is experimental evidence, include longer-lived infected cells such as macrophages and resting CD4+ T cells, dissociation of virus from the FDC network, and productively infected CD4+ T cells that are not subject to clearance by host immune responses because of waning levels of HIV antigen. Raltegravir (MK-0518) belongs to a new class of integrase inhibitors that potently suppress HIV and SIV replication, and reportedly markedly alters the second phase HIV decline in a way that challenges the current view that longer-lived infected cells are the source of virus in this phase. While mathematical modeling of decay of HIV RNA in blood was most consistent with 1) cells newly infected by long-lived cells, or 2) from activation of latently infected cells with full-length unintegrated HIV DNA as a source of second phase virus, we think the data are also quite consistent with the greater efficacy of integrase inhibitors in a particular cell type and/or anatomic site such as the gut. In this protocol we will test the hypothesis that the rapid decrease in HIV replication associated with raltegravir is due to a more complete suppression of viral replication in lymphatic compartments such as lymph nodes and gastrointestinal lymphatic tissue. We will also investigate compartment-specific intracellular levels of raltegravir to potentially explain differences in changes in these compartments.

i2-D²EFT substudy is an observational cohort nested within the parent D²EFT study (NCT03017872). D²EFT goal is to compare the standard of care second-line antiretroviral therapy in people living with HIV whose first-line non nucleoside reverse transcriptase-based regimen failed, to two simpler regimens. Approximately 1,000 participants will be enrolled in D²EFT. Commencing a second-line ART is an important moment when the level of inflammation in participants may be elevated due to first-line ART failure; this level of inflammation should then decrease with the commencement of a new second-line treatment and would be expected to normalise by 48 weeks of second-line treatment, if successful. The investigators propose to study other factors which can influence the decrease of inflammation. The investigators hypothesise that co-infections may play a role in persistent inflammation. The key-infections of interest will be common frequent infections encounter throughout the world: Human Herpes virus 8, Epstein-Barr virus, Cytomegalovirus and Human papillomavirus, tuberculosis, malaria and other key opportunistic infections. Possible changes of level of inflammation (using the serum level of Interleukin 6) in approximately 200 participants of the D²EFT study will be investigated and measured. The hypothesis is that the presence of other infections than HIV may influence the level of inflammation in participants in therapeutic success.

This is a single-center, open-label, three-period, fixed-sequence cross over study in healthy adult subjects. A total of approximately 16 healthy subjects will be enrolled to provide data from 12 evaluable subjects. Subjects will have a screening visit within 30 days prior to the first dose of study drug, three treatment periods, and a follow-up visit 7-14 days after the last dose of study drug. There will be a washout period between Period 1 and Period 2 but no washout between Period 2 and Period 3. Day 1 of Period 3 will be the day after Day 5 of Period 2.
