Filter by:This study is a prospective, open-label, single-site, first-in-human study of a long-acting, injectable combination antiretroviral therapy platform, with a pharmacologically-guided adaptive design for dose escalation, de-escalation, and study duration. The study is designed to learn whether the formulation can be used as a platform for other drugs for treatment of HIV. The formulation is a drug combination nanoparticle (DCNP). The study will be conducted by UW Positive Research. The sample size for this study is 12-16. The study population consists of healthy adults without HIV. The study duration is 57 days per participant at the start of the study.
The goal of this observational study is to understand patterns of HIV transmission in a high-prevalence area in Ethiopia, and to compare viral genetic information in people with HIV who are newly diagnosed and have not been exposed to antiretroviral therapy with persons receiving antiretroviral therapy without viral suppression. The main questions it aims to answer are: - Do people with HIV who fail to achieve viral suppression contribute to the ongoing spread of HIV in Ethiopia, or does HIV transmission mainly occur between persons with no exposure to such therapy? - Are viruses with drug-resistance mutations transmitted onwards from people with HIV receiving antiretroviral therapy who fail to achieve viral suppression? * Which factors are involved in treatment failure and emergence of drug-resistant viruses longitudinally? Participants will be enrolled with regard to history of antiretroviral therapy exposure (newly diagnosed/treatment-naïve vs. treatment-experienced with lack of viral suppression), using persons on antiretroviral therapy with viral suppression for control. We will compare the following outcomes between these groups: - Clustering of viral genetic sequences at inclusion (implying linked transmission) - Prevalence of drug-resistance-associated mutations at inclusion - Viral suppression and emergence of drug-resistance mutations during follow-up
This study will investigate the use of a next-generation Reader as part of a digital pill system (DPS; ID-Cap System) to measure adherence to both antiretroviral therapy (ART) and pre-exposure prophylaxis (PrEP) in people living with HIV (PLWH) and HIV-negative individuals, respectively. During the first (non-human subjects) component of this study, we developed a wrist-borne Reader according to design specifications and preferences shared by DPS users from our previous studies. Early bench testing by etectRx (manufacturer of the ID-Cap System) demonstrated that the wrist-borne version of the Reader acquires signal from the digital pill. This study will therefore evaluate the usability of and user response to a wrist-borne Reader component of the DPS among PLWH on ART and HIV-negative individuals on PrEP.
In its 2017 revision of the global guidelines for HIV care and treatment, the World Health Organization (WHO) called for rapid or same-day initiation of antiretroviral treatment (ART) for eligible patients testing positive for HIV. However, to date neither the WHO nor the Zambia Ministry of Health has provided detailed guidance on how to implement this recommendation. In sub-Saharan Africa, where most HIV patients are located, studies continue to document high losses of treatment-eligible patients from care before they receive their first dose of antiretroviral medications (ARVs). Among facility-level reasons for these losses are treatment initiation protocols that require multiple clinic visits and long waiting times before a patient who tests positive for HIV is dispensed an initial supply of medications. There is very little published evidence on the practical details of the process and the extent to which it varies by facility, setting, or country. Without a robust baseline evidence base, it is challenging to identify opportunities for making improvements. The SPRINT (Survey of Procedures and Resources for Initiating Treatment of HIV in Africa) study will begin to develop this evidence base. SPRINT will combine a facility-level description of the standard of care with a retrospective record review of patients who recently initiated ART at the study sites. Data will be collected from 12 health facilities in Zambia. The survey will elicit detailed information about current procedures through structured interviews with clinic staff at the selected health facilities. The record review for a retrospective cohort of patients eligible for ART will estimate actual numbers of clinic visits, services provided, and duration of the steps for treatment initiation from start to finish. SPRINT is expected to identify differences in approaches to treatment initiation and potential opportunities for improvement.

This randomized trial compares the efficacy of switching to a fixed-dose combination of B/F/TAF versus continuing a boosted protease inhibitor (bPI) regimen in HIV-1 infected participants who are virologically suppressed (HIV-1 RNA <200 copies) on a second-line bPI regimen. Half of participants will receive B/F/TAF and half will continue a bPI regimen. The hypothesize is that B/F/TAF will have efficacy that is non-inferior to the boosted PI regimen.
In its 2017 revision of the global guidelines for HIV care and treatment, the World Health Organization called for rapid or same-day initiation of antiretroviral treatment (ART) for eligible patients testing positive for HIV. The South African National Department of Health adopted this recommendation in October 2017. Neither organization provided detailed guidance, however, on how to implement the recommendation. In sub-Saharan Africa, where most HIV patients are located, studies continue to document high losses of treatment-eligible patients from care before they receive their first dose of antiretroviral medications (ARVs).

SPRINT will combine a facility-level description of the standard of care with a retrospective record review of patients who recently initiated ART at the study sites. Data will be collected from 12 clinics across 3 provinces in South Africa (KwaZuluNatal Province, Gauteng Province, and Limpopo Province). The survey will elicit detailed information about current procedures through structured interviews with clinic staff. The record review for a retrospective cohort of patients eligible for ART will estimate actual numbers of clinic visits, services provided, and duration of the steps for treatment initiation from start to finish. SPRINT is expected to identify differences in approaches to treatment initiation and potential opportunities for improvement.
Antiretroviral therapy (ART) has been a game changer in the context of HIV-epidemic. From 2005 to 2015, HIV-related deaths have fallen by 45% thanks to ART. However, ART's success heavily depends on HIV-positive individuals' high adherence to it. This includes clinic attendance for various purposes. It is necessary among HIV-positive individuals for their antiretroviral (ARV) pills pick up, monitoring of their treatment outcomes, and treatment of their opportunistic infections. Among them, ARV pills pick up is the major reason for the ART clinic attendance. Improving clinic attendance for pills pick up remains one of the key challenges to ART programs. The World Health Organization (WHO) recommends more than 90% on-time ARV pills pick up as per the early warning indicators of HIV-drug resistance. Among six Asian countries, none of the 1048 clinics under the study could meet the WHO target. Among HIV-positive individuals, clinic attendance for pills pick can be improved by using mobile phones. Those who receive mobile phone reminders are two times more likely to attend their clinics regularly than those who did not receive such reminders. Nepal belongs to a low-income country and is facing a similar problem, too. In 2015, approximately 39,000 people were estimated to be living with HIV and ART coverage was limited to only 31.5%. In the same year, only 32% of the HIV-positive individuals attended their clinics regularly for ARV pills pick up. Like other countries, one of the potential strategies is to use mobile phones effectively in Nepal. Mobile phones have been very widely used in Nepal. In 2016, Nepal had 27.9 million mobile phone users, against the population of 26.5 million. Under such a context, mobile phone reminders can be effective to improve clinic attendance among HIV-positive individuals. However, the effectiveness of such interventions barely remains examined by using a randomized controlled trial. This study evaluates the effectiveness of mobile phone reminder intervention on improving clinic attendance for ARV pills pick up and medication adherence among HIV-positive individuals on ART following the implementation of test and treat strategy in Nepal.
In its 2017 revision of the global guidelines for HIV care and treatment, the World Health Organization called for rapid or same-day initiation of antiretroviral treatment (ART) for eligible patients testing positive for HIV. In sub-Saharan Africa, where most HIV patients are located, studies continue to document high losses of treatment-eligible patients from care before they receive their first dose of antiretroviral medications (ARVs). Among facility-level reasons for these losses are treatment initiation protocols that require multiple clinic visits and long waiting times before a patient who tests positive for HIV is dispensed an initial supply of medications. Simpler, more efficient, accelerated algorithms for ART initiation are needed, including strategies for rapid initiation in patients with symptoms of tuberculosis, most of whom do not have active TB. In July 2017, the original SLATE study (SLATE I) completed enrollment in South Africa. One of the most striking findings of the study so far is the large proportion of patients who "screened out" of the SLATE algorithm and were referred for additional services rather than started on ART immediately. Among 298 patients assigned to the intervention arm and evaluated for immediate treatment eligibility under the SLATE algorithm, 149 (50%) screened out, two thirds of these (100/149) due to symptoms of TB. The vast majority of the TB suspects (93/100, 93%) tested negative for active TB. The SLATE II study will revise the original SLATE algorithm to provide a pathway for immediate ART initiation for some patients with TB symptoms. Under SLATE II, patients with TB symptoms will be clinically evaluated by the study nurse and will receive a urine point of care LAM (lipoarabinomannan antigen of mycobacteria) test. Those with milder symptoms and a negative LAM test will be offered immediate ART. Those with more serious symptoms and/or a positive LAM test will be asked to return the next day to receive TB test results and either immediate ART or TB treatment. All intervention arm patients (symptomatic and asymptomatic) will be asked for a sputum sample for Xpert testing, and positives will be contacted on the next day. The SLATE II algorithm will also incorporate other improvements identified from SLATE I.
The purpose of this study is to evaluate whether maintenance antiretroviral therapy could be simplified to DTG + FTC dual therapy and/or patient-centered monitoring once virological suppression is achieved. Using a factorial design, the study aims to assess the efficacy of DTG + FTC dual therapy to maintain virological suppression through 48 weeks of follow-up as well as the costs of a patient-centered ART laboratory monitoring.
