NCT04240509
Background: Several major studies have demonstrated the success of Truvada as pre-exposure prophylaxis (PrEP) in preventing HIV infection.The CDC guidelines recommend PrEP for people who are at elevated risk of HIV including men who have sex with men (MSM) and people who use injection drugs. People who are incarcerated bear a disproportionate of disease burden, including HIV. Furthermore, men who have been involved with the criminal justice system are more likely to engage in risky behaviors following their release, including condomless sex with partners of unknown serostatus, and injection drug use. The incarceration setting provides a place to engage men who may be at risk of HIV after they are released. Following release, community clinics, including the STD clinic at The Miriam Hospital (TMH) Immunology Center, that perform routine testing for HIV and other sexually transmitted diseases (STDs) may be ideal settings to engage vulnerable populations in care, including PrEP. Despite the demonstrated clinical efficacy of PrEP in reducing HIV transmissions, few clinical programs have piloted the use of PrEP in real-world settings, particularly criminal justice settings. Furthermore, studies demonstrate numerous challenges to PrEP uptake and adherence, including a lack of access or discontinuing care. Engaging at risk men in PrEP care before they leave prison and potentially lost to care during the transition may increase uptake, adherence, and retention. Objective: This study protocol will evaluate a clinical program that aims to prevent new HIV infections among recently-incarcerated men using a once daily dosing of tenofovir/emtricitabine (Truvada) as pre-exposure prophylaxis (PrEP). This protocol presents an overview of the clinical program, which uses standard-of-care clinical practices and Centers for Disease Control and Prevention (CDC) guidelines for prescribing and monitoring PrEP. Male inmates at the Rhode Island Department of Corrections (RIDOC) will be screened for HIV risk and, if eligible and interested, will be prescribed and given a one-month supply of PrEP shortly before their release, and receive follow up care at The Miriam Hospital (TMH) Immunology Center following their release.
NCT00552214
The purpose of this study is to validate the performance characteristics of an assay that tests for HIV-1, HCV and HBV on an automated blood bank instrument for registration submission.
NCT03308097
This study will develop and test an interactive mobile messaging intervention to improve engagement in care related to Pre-exposure Prophylaxis (PrEP) and decrease HIV risk behaviors for Black men who have sex with men living in the Southern U.S. The mobile messaging intervention will include interactive text messaging and free, publicly available links to websites and YouTube videos. During the intervention participants will gain information about their health, improve motivation for engagement in PrEP related care, and build skills for healthy behaviors. Participants will also receive intervention materials to help decrease frequent barriers to care. If the intervention is found to be effective, it can be tested in a larger study and then disseminated.
NCT02953080
Current estimates point towards a huge increase in the number of people that are eligible to start ART in Uganda and globally. As many of the newly eligible patients are largely asymptomatic, there are concerns about adherence and retention of these individuals and especially those starting ART with a higher CD4 counts. Urgent information is required to plan for implementation of most recent WHO and National guidelines in the most cost effective manner as well as maximizing retention of HIV positive individuals in care and achieving virological suppression. The investigators plan to undertake research designed to see if investigators can optimize adherence, virological outcomes and HIV knowledge, in order to give an overall increased quality of life in vulnerable populations starting or established on ART in Kampala, Uganda. The investigators will test implementation of an open source software-based tool to send text messages and to give access to an interactive voice response system using patients' mobile phones. The investigators' aim to undertake an open labelled randomised trial at two sites: the IDI which is an urban centre of excellence in HIV care, and Kasangati Health Centre, which is a peri-urban public health care facility. The project aims to enrol HIV positive patients starting ART, already established on first line ART or switching to second line ART, including special populations (pregnant women, discordant couples and young people). The estimated length of the project is 30 months. The technology to be evaluated in this study is based on CONNECT FOR LIFETM m-health technology (CFL2015.01 or higher), which provides text messages or Interactive Voice Response (IVR) functionalities, and allows a computer to interact with humans through the use of voice and tones input via keypad and offers pill reminders, clinic visit reminders, health tips and support symptom reporting. Primary Objective is to determine the effect of the CFL2015.01 tool on quality of life of HIV patients receiving care at IDI and Kasangati HCIV. At the start of the intervention, all patients will undergo quality of life assessment, which will be repeated at months 6, 12, 18 and 24 months. The scores will be compared to assess the effect of the tool on quality of life. The Secondary Objectives are virological outcomes baseline, 6, 12,18 and 24 months, retention in care, aversion of early treatment failure, disease knowledge, clinic attendance and cost analysis.
NCT00119106
The primary goals of this study are to assess the safety and efficacy of daily tenofovir to prevent parenteral HIV infection among injection drug users (IDUs). Assessment of changes in HIV associated risk behaviors, adherence to study drug, and, among IDU who become HIV-infected during the trial, evaluation of HIV viral load set point, CD4 counts, genetic characterization of infecting HIV viruses, and antiretroviral resistance will also be done.
NCT04062253
Data on the prevalence of hepatitis C virus (HCV) for other vulnerable groups in Madrid, such as homeless persons and migrants, are scarce, and it is now necessary to implement intervention and elimination plans. Vulnerable groups have poor access to healthcare and are therefore not systematically screened for HCV. On the occasions they are shown to be positive, subsequent follow-up in the health system and the possibility of cure are poor. The use of a mobile unit to approach vulnerable populations is essential for better characterization of risk behaviors and of the magnitude of HCV. The integration of healthcare personnel in mobile units enables counseling on prevention and intervention when needed. Primary objective Evaluate the impact of the HCV care cascade on vulnerable populations who gather at hot spots in Madrid (shantytowns, homeless shelters and places were street prostitution is practiced) by means of a multilevel outreach project. SURVEILLANCE: Active screening for HCV among vulnerable individuals in populations with a high prevalence of HCV will be carried out in hot spots in Madrid, namely, Cañada Real shanty town, mobile harm reduction units, institutions providing social assistance, public areas, homeless shelters and places where street prostitution is practiced. An agreement with the Madrid Council (MCC) is under way to provide social centers for HCV screening. A mobile unit will approach the hot spots following a predefined schedule. The mobile unit consists of a van adapted for the project and a car. HCV screening of vulnerable individuals will be performed by a nurse and an educator hired specifically for that purpose. Active HCV screening and prevention in vulnerable individuals should be a priority and a responsibility shared by both the MCC and the SERMAS (Servicio Madridleño de Salud). The investigators plan to establish an agreement with public health authorities to give continuity to this project and to carry out proactive HCV screening through integration with various centers and networks dependent on the MCC and SERMAS. The project will establish the foundations of integrated cooperation between an HCV clinic in a hospital setting and harm reduction units and other resources and networks dependent on the institutions mentioned above. As has been observed with other interventions, the functional objective of this project is to provide continuity of care from the institutions. Study Duration (in months) 12 months.
NCT03824067
This mixed methods study will utilize a randomized step-wedge design to assess the impact of point-of-care (POC) versus conventional early infant diagnosis (EID) on key outcomes including timely return of results to caregivers and time to initiation on treatment for HIV-infected infants. Data will be collected through longitudinal clinical follow-up and medical chart extraction of routine records and lab forms. Feasibility and acceptability data will be collected through interviews with mothers/caregivers of HIV-exposed infants, and community focus groups.
NCT03751046
Highly active antiretroviral therapy (HAART) has been the greatest achievement to control the HIV/AIDS epidemic in the world. HAART has been shown to reduce virus replication to undetectable levels and to favor the recovery of immune function, avoiding the occurrence of opportunistic diseases. Although existing treatments have been shown to lower AIDS-related morbimortality and to increase patients' quality of life, the success of HAART requires high levels of adherence to the prescribed treatment regimen. Adherence to HAART has become the major challenge for global public policy managers and healthcare teams involved in the care of HIV/AIDS patients. Mental healthcare professionals should use structured and effective intervention as strategies to facilitate a better approach, increase patients' autonomy and achieve optimal adherence. Trial-Based Cognitive Therapy (TBCT) is a new, structured, and short-term version of cognitive behavior therapy developed by de Oliveira (2011). TBCT is an active approach that aims to change negative cognitions, especially dysfunctional core beliefs, that negatively influence patient's life in different domains. TBCT helps patients recognize situationally based thoughts, unhelpful beliefs and maladaptive behaviors that exacerbate emotional distress. This study aims to assess the efficacy of TBCT in helping the patients to identify thoughts, emotions, assumptions and behaviors associated with non-adherence to antiretroviral therapy, and to improve adherence to treatment.

NCT03315013
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.
NCT03536234
An open, randomised, parallel arm phase IIa study. 52 HIV-1 infected patients will be randomised (in a 1:1 ratio) to either an active group or a control group. The active group will receive the GnRH analogue triptorelin depot monthly at baseline, week 4 and week 8. Patients in the active group and in the control group will continue their triple combination antiretroviral therapy (ART) during the study without changes; unless there is rationale for change on medical ground. In order to prevent the negative effects of a low testosterone level, patients in the active group will be offered to receive a single intramuscular depot injection of testosterone approximately 7 days after triptorelin treatment. This depot administration will keep the serum testosterone on a normal level until the next triptorelin dose. This will be repeated when triptorelin is administered at week 4 and week 8. Total study period is 24 weeks.
NCT02178592
HIV/Tuberculosis (TB) co-infection have profound effects on the host's immune system. TB is the most common cause of death in patients with HIV worldwide. Rifamycins (such as rifampicin \[RIF\]) are an important component of TB therapy because of their unique activity. The problem is that most protease inhibitors (PI) and non-nucleoside reverse transcriptase inhibitors (NNRTI) used to treat HIV have significant drug-drug interactions with RIF that can lead to reduced concentrations of these agents with risk of treatment failure or resistance. The non-nucleoside reverse transcriptase inhibitor (NNRTI) efavirenz (EFV) does not present the same significant drug interactions with RIF. EFV-based HIV treatment was tested in patients concomitantly treated with RIF-containing TB therapy, demonstrating that their co-administration can be used safely and effectively. However, the side effect profile of EFV overlaps with the RIF-containing TB regimens and makes the management of treatment toxicities very complex. Integrase inhibitors (INI), such as dolutegravir (DTG), may offer an important alternative to EFV-based therapy in TB coinfected patients. A Phase I drug-drug interaction study was conducted in healthy, HIV-seronegative subjects, and showed that DTG at 50 mg twice daily given together with RIF was well-tolerated and resulted in DTG concentrations similar to those of DTG 50 mg given once daily alone, which is the recommended dose for INI-naive patients. Therefore, ART regimens using DTG 50 mg twice daily may represent a new treatment option for TB-infected patients who require concurrent treatment for HIV infection. This is a Phase III b, randomized, open-label study describing the efficacy and safety of DTG and EFV-containing ART regimens in HIV/TB co-infected patients. This study is designed to assess the antiviral activity of DTG or efavirenz (EFV) ART-containing regimens through 48 weeks. A total of approximately 115 +/-5% subjects will be randomly assigned in a 3:2 ratio to DTG (approximately 69 subjects) and EFV (approximately 46 subjects), respectively. This study will include a Screening Period, a Randomized Phase (Day 1 to 48 weeks plus a 4-week extension), and a DTG Open-label extension (OLE). During the DTG OLE, subjects will be supplied with DTG until it is locally approved and commercially available, the subject no longer derives clinical benefit, or the subject meets a protocol-defined reason for discontinuation, which ever comes first.
NCT04702412
Adherence to antiretroviral therapy (ART) remains problematic. Our team has thus developed a new patient-reported measure of barriers to ART adherence (the I-Score) which will be completed by HIV patients through the Opal patient portal for routine HIV care. This 6-month mixed method pilot study will implement the I-Score/Opal intervention with 5 HIV physicians at the McGill University Health Centre (Montreal, Quebec) and 30 of their patients. The study's primary objectives are to assess patient and physician perceptions of the intervention (e.g., acceptability) and evaluate the implementation strategy. The data collected will help plan and determine the feasibility of a definitive effectiveness trial.
