This is an open-label, single arm, phase I study to determine the safety, PK characteristics and anti-inflammatory effects of the NK-R1 coadministered with ritonavir-containing antiretroviral therapy in individuals with well-controlled viral replication. Our hypothesis is that Aprepitant will be safe, well tolerated, and will have anti-inflammatory properties when administered concomitantly with the protease inhibitor ritonavir.
Canada continues to see an unrelenting stream of new HIV diagnoses, with a disproportionate burden among gay, bisexual, and other MSM in major centers such as Toronto. Pre-exposure prophylaxis (PrEP) with oral, daily tenofovir/emtricitabine (TDF/FTC, Truvada®) is a novel biomedical approach to HIV prevention shown in the iPrEx trial to be safe and efficacious in reducing HIV acquisition by 44% among MSM, when provided in a comprehensive package of HIV prevention interventions including counseling, testing/treatment of sexually transmitted infections (STIs), and condoms. There is now widespread mobilization to assess the feasibility of PrEP roll-out worldwide, with urgent calls for 'demonstration projects' addressing real-world PrEP implementation issues. PREPARATORY-5 is Canada's first PrEP demonstration project, and will examine real-world PrEP implementation issues including acceptability, effectiveness, impact on sexually transmitted infections, and strategies for supporting adherence outside the clinical trial setting. The investigators have also established a comprehensive community-based research program investigating the role of community-based organizations in PrEP implementation and delivery.
Female sex workers (FSWs) in India are at high risk of HIV infection, and while correct and consistent condom use is an effective means of preventing HIV transmission, many FSWs have difficulty insisting on their use. Alternative HIV prevention options are needed for FSWs who are unable to correctly and consistently use condoms with their clients or regular partners. Oral pre-exposure prophylaxis (PrEP) may be an important tool to fill this critical prevention gap, and a demonstration project is required to assess the impact and feasibility of the use of PrEP as an HIV prevention intervention among most at risk FSWs in India. The proposed project will take place at two sites in India and will assess the use of a risk assessment tool to identify FSWs who would most benefit from PrEP, collect information about the reasons why FSWs choose to accept or decline PrEP, evaluate two different PrEP delivery strategies (weekly clinic pick-up or home delivery by peer educators every second day), monitor adherence to and discontinuation of PrEP, and evaluate unintended consequences of the use of PrEP in these communities (e.g. reduction of condom use, drug side effects or adverse events, social harms or resistance). To ensure the safety of study participants, a community advisory board will be set up and will meet regularly to inform study staff of any concerns that the community may have related to the study, so that the study staff can respond in a timely manner. A data safety and monitoring board will also be established to monitor participant safety.
IMPAACT P1107 will describe the outcomes of HIV-infected persons, ages 12 months and older, who undergo transplantation with CCR5Δ32 cord blood stem cells for treatment of cancer, hematopoietic disease, or other underlying disease.
The purpose of this study is to provide dosing recommendations for the coadministration of BMS-663068 and Rifabutin with and without Ritonavir in upcoming Phase 3 studies and for prescribing information purposes
Building upon the successful qualitative Phase I of the study, Phase II commences in month 10. The Project manager and research staff will recruit 600 women living with AIDS (WLA) and their oldest child between the ages of 3 and 8. The WLA will be recruited from Primary Health Centers (PHCs) randomly selected from 72 closest PHCs in terms of HIV prevalence in the rural Andhra Pradesh (AP) area of Nellore. WLA will be recruited by means of approved flyers posted in selected PHCs. Interested WLA will approach the research staff, stationed at the PHC to be screened for eligibility via a consent script. Once eligibility is determined for the WLA, based upon the following criteria: age, HIV and ART status (validated by ART and HIV card); having a child (3-8 years) and whether or not the WLA was a participant of the previous intervention group from the Asha pilot study, a parental consent will be obtained from the WLA for permission to include her oldest child in the study. The oldest child between 3-8 years of age will be brought in to the research office or PHC (after mother speaks with the child at home). All children will have blood work drawn and physical health assessment on their first visit (total of 15 minutes). All eligible WLA will undergo a second consent for enrollment. General Procedure: Following informed consent, the WLA will be randomly assigned into one of four programs 1) Asha Support Only; 2) Asha Support + Training; 3) Asha Support + Food; or 4) Asha Support + Training + Food. After blood draw and physical assessment of the WLA, an appointment will be made for the assigned interviewer (blinded to program) to visit the WLA at their home preferably (or other location of choice) to conduct several 24 hour dietary assessments. Urine will be collected in labeled bottles on the morning after the 3rd day of the diet recall by the interviewer and sent directly to the lab in a cooler. Also, on the same day, the baseline assessment will be entered into the PC tablets; 50 minutes estimated with breaks). After a longer break, the WLA will then be asked to respond to additional questions about the sociodemographic and psychomotor development of their child (about 30 minutes). Interviewers will visit the WLA monthly until the end of the intervention (month 6) to provide individual weekly Asha Support and conduct group sessions and collect ongoing data, 24-hour recall, and ART pill count for WLA, and follow up questionnaires at 6-, 12- and 18-months.
Microbicides are topical medicines that can prevent infection by Human Immunodeficiency Virus (HIV). Microbicide medicine has yet to be studied in adolescents, a key group that is becoming infected with HIV all over the world. From past research, we know that at different ages people experience age-related changes in their bodies that can cause differences in how they process medications. In this study, gut tissue samples (or gut biopsies) from 12 HIV-negative volunteers will be collected. These pieces of tissue will be infected with HIV in the laboratory to develop a model that can be used to test certain drugs against the HIV infection. We can use this tissue to test a drug called tenofovir against HIV infection. We will determine whether this drug can decrease HIV infection in the gut biopsies. In this study, we will also measure HIV levels and the levels of tenofovir in gut and blood samples in 12 people who are already taking this drug. This information can determine whether levels of drug found in the gut can protect it from HIV. The results can be compared to other age groups of adolescents and adults. Subjects will undergo a common procedure called a lower endoscopy (this can be a colonoscopy or a flexible sigmoidoscopy) to obtain gut biopsy samples. The central hypothesis is that tissue drug profiles of tenofovir (TFV) and its active component, tenofovir disoproxil fumarate (TDF), and tissue infectibility vary between younger (10-14 years old) versus older adolescents (18-21 years old), and that both differ from adults (>21 years). Specifically, younger HIV positive adolescents will have lower levels of tissue tenofovir compared to older HIV positive adolescents and adults in an age-dependent manner. Additionally, biopsies from younger HIV negative adolescents will have: 1) higher rates of infection compared to biopsies from older HIV negative adolescents infected with a lower dose of virus; and 2) lower percent suppression of tissue infectivity compared to biopsies from older HIV negative adolescents using low dose tenofovir.
To evaluate the safety and efficacy of reformulated raltegravir (MK-0518) 1200 mg once daily in combination with TRUVADA™ versus raltegravir 400 mg twice daily in combination with TRUVADA™ in HIV-1 infected, treatment-naive participants. The primary hypothesis being tested is that reformulated raltegravir 1200 mg once-daily is non-inferior to raltegravir 400 mg twice-daily, each in combination therapy with TRUVADA™, as assessed by the proportion of participants achieving HIV-1 ribonucleic acid (RNA) <40 copies/mL at Week 48.
The study hypothesis is that cenicriviroc will improve cognition in HIV infected individuals with cognitive impairment. The investigators will study the effect of cenicriviroc on cognition in 24 subjects over a 24 week period.
