Active clinical trials for "Acquired Immunodeficiency Syndrome"

The goal of this study is to understand the interaction between HIV and the host at the earliest stages when HIV medications are paused. Volunteers with HIV will interrupt antiretroviral therapy (ART) and then have intensive studies preformed two to three times per week. Most will resume therapy within three weeks, even if the virus does not rebound during this time.

The Visceral Adiposity Measurement and Observation Study

With HIV/AIDS increasingly considered a chronic disease, 24-, or 48-week data from antiretroviral studies are no longer sufficient. Only with long-term follow-up and outcome data will shed some much-needed light on the answers of questions that have stumped us for several years. Data from a large observational cohort of patients treated with combination antiretroviral therapy will provide further insights into the long-term safety and durability of various antiretroviral therapeutic approached, the efficacy of HIV viral load and CD4 cell counts as predictors of disease progression and mortality, and the importance of adherence.

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.

Client-Centered Representative Payee is a structural intervention that provides financial management support to PLWHA by modifying the implementation of a long-standing policy within the Social Security Administration, in which an organization is authorized to serve as the client's payee. The central hypothesis of this study is that by helping clients to pay rent and other bills on time, housing stability will improve and financial stress will decrease. By reducing the cognitive burden of living with chronic financial stress and frequent threats of housing loss, clients can devote more time and attention to medical appointments and medication adherence. It is further hypothesized that these changes will improve clients' self-efficacy for health behaviors, retention in care, medication adherence, and viral loads. These hypotheses will be tested via the following specific aims: (1) Conduct a randomized controlled trial with two randomized arms (n=160) and two non-randomized arms (n=50) to test the effect of Client-Centered Rep Payee on ART adherence and viral load among PLWHA who are economically disadvantaged and unstably housed. Clinical adherence will be compared through behavioral and biological measures including prescription refill data, self-reported appointment adherence, and viral load for patients receiving the intervention versus those receiving standard of care. (2) Test underlying mechanisms associated with Client-Centered Rep Payee that contribute to changes in medication adherence and viral suppression rates. This will be accomplished via use of quantitative (mediation analysis) and qualitative (semi-structured interview) methods to test hypothesized mediators of medication adherence and viral suppression including financial and housing instability, financial stress, self-efficacy for health behaviors, and retention in care. (3) Assess the cost and cost-effectiveness of the Client-Centered Rep Payee model. An economic analysis will be conducted to model the impact of the intervention as compared with standard of care on quality adjusted life years as well as new infections averted. This approach is innovative because it offers a structural intervention to improve adherence by addressing the effects of economic insecurity, requires low financial investment, and can be layered with existing clinical services. Further, it is highly scalable as it builds on a current policy in practice within the Social Security system.

It is important to make sure that women have access to effective methods of contraception to prevent pregnancy so that they can make choices about when and if they will have their first or next child. Some of the most effective methods of contraception are the long-acting, reversible methods of contraception (LARCS), including the contraceptive implant and the contraceptive injection. In areas of the world where there are high numbers of people living with HIV, providing contraception to women is sometimes complicated, as there are known to be interactions between some of the medications that treat HIV and some hormonal methods of contraception. One medication to treat HIV, dolutegravir, is now one of the first-line treatments for HIV in Botswana, and more and more women of childbearing age are taking dolutegravir to treat HIV. At the moment, there is limited information on whether or not there are interactions between dolutegravir (the HIV medication) and the contraceptive implant or the contraceptive injection, two commonly used methods of contraception in Botswana. The main purpose of this study is to find out if women using contraception and also taking dolutegravir have lower levels of contraceptive hormone in their blood compared to women taking no HIV treatment. The study hypothesis is that there is no interaction between dolutegravir and the contraceptive implant or injection. In this study, levels of hormone from the injection or the implant will be measured in women living with HIV who take dolutegravir and compared to hormone levels in women who do not have HIV and who have never taken any medications to treat HIV. Women will be counselled about all of the possible methods of contraception (including the pill, the injection, the implant and the copper intrauterine device (or coil/loop)) that are available and will be empowered to make their own decision about the method of contraception they feel will be best for them. Women who choose the implant or the injection will be invited to enrol in the study; and will be categorised into one of four groups, based on whether or not they are living with HIV and taking dolutegravir. At several time points, women will have blood tests to check the level of hormone from the implant or the injection, over a course of 12 weeks for women starting the injection and 24 weeks for women starting the implant. Women will also be asked to complete a short questionnaire about any side effects from the contraception including changes to bleeding patterns. At the end of the 12 weeks (for women starting the injection) or 24 weeks (for women starting the implant), the results from these blood samples will be analysed to see how the levels of the hormone in their blood changed over time. The study will also look at whether the levels of dolutegravir (the HIV medication) changed over time. These results will be compared between women living with HIV taking dolutegravir and women without HIV who have never taken dolutegravir to see whether there is any interaction between dolutegravir and the hormonal contraceptive implant or contraceptive injection.

Uganda uses a threshold of 1,000 copies/ml to determine HIV viral non-suppression among people living with HIV/AIDS (PLHIV) on treatment, which is indicative of either poor adherence or HIV virologic treatment failure; as per the recent WHO recommendations. The use of this high threshold of 1,000 copies/ml has resulted into an increase in the number of PLHIV having low-level viraemia (≥50 to <1,000 copies/ml) from 11.0% in 2017 to 35.0% in 2020 in Uganda. Different studies in developed countries have shown that low-level viraemia is associated with HIV drug resistance, and despite this, there is no intervention to manage and control low-level viraemia (LLV), as per the recent Uganda national HIV guidelines. With this increasing and unmanaged low-level viraemia (LLV), Uganda might never achieve the global targets of ending AIDS as epidemic by 2030, as stipulated by target 3.3 of SDG 3. This study will therefore determine the effectiveness of intensive adherence counselling on achieving a non-detectable viral load (below 50 copies/ml) in the management of LLV among PLHIV on ART in Uganda. This study will generate useful information that might guide the review of the national HIV guidelines, to control and manage LLV among PLHIV on ART; and thereby enable Uganda to achieve the global goals of SDG 3, Target 3.3 and the national targets of Vision 2040.

The study is a single-centre, open-label, fixed-sequence, self-controlled clinical trial. It is planned to enroll 20 healthy adult subjects. Subjects will take SHR2150 on Day 1 and Day 21, and take efavirenz from Day 7 to Day 26.

This study will evaluate the impact of the Common Elements Treatment Approach (CETA), an evidence-based intervention comprised of cognitive-behavioral therapy elements, at improving HIV treatment outcomes among women with HIV who have experienced intimate partner violence (IPV) and have an unsuppressed viral load on HIV treatment. To evaluate CETA, the investigators will conduct a randomized controlled trial of HIV-infected women, with or without their partners, who have experienced IPV and have an unsuppressed viral load to test the effect of CETA in increasing viral suppression and reducing violence. The investigators will also identify mediators and moderators of CETA's effect on retention and viral suppression and assess the cost and cost-effectiveness of CETA vs. active control at increasing the proportion who are retained and virally suppressed by 12 months.

The overall goal of this study is to evaluate the effects of the CHAMPS intervention for people living with HIV (PLWH) in a randomized controlled trial. The proposed trial is scientifically significant in representing a principled and systematic effort to test the efficacy of a combined community health worker (CHW) and smartphone intervention linked to a smart pill box for antiretroviral (ART) adherence in PLWH in the United States (US). Guided by a rigorous theoretical model of supportive accountability and building on preliminary work, this intervention has the potential to enable PLWH to self-manage their ART regimens while CHW monitor their ART adherence in real-time ultimately leading to viral suppression and ART adherence.
