Filter by:This open-label, fixed-sequence crossover study aims to evaluate the effect of GSK1265744 (744) oral administration on the pharmacokinetics (PK) and pharmacodynamics (PD) of a commonly used oral contraceptive (OC) product (combination of ethinyl estradiol and levonorgestrel), in 20 healthy female subjects. Each subject will participate in a Run-in Period (if needed), followed by a single-sequence Treatment Period. Subjects will receive oral contraceptive containing Levonorgestrel and Ethinyl Estradiol on Days 1 to 21 and be OC free on Days 22 to 28, during which withdrawal menses should occur. Subjects will receive OC alone on Days 1 to 10. Levonorgestrel (LNG) and ethinyl estradiol (EE) PK will be determined on Day 10. Subjects will then co-administer 744 and OC on Days 11 to 21. Levonorgestrel and ethinyl estradiol PK will be determined again on Day 21 to assess if co-administration with 744 results in a significant change in OC exposure compared to OC alone. Subjects will return to the study center for final follow-up evaluations 7 to 14 days after the last dose of study medication (Days 28 to 35).
The purpose of this study is to assess the effect of BMS-955176 on the pharmacokinetics of coadministered oral contraceptives.
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.
The purpose of this study is to contribute evidence towards the potential to improve cognition in HIV+ individuals experiencing cognitive decline through personalized change in antiretroviral (ARV) medication. To that end, following a comprehensive evaluation to identify confounding clinical conditions, study participants will undergo a lumbar puncture to: (i) measure viral load (at 2 copies/ml); (ii) identify Cerebrospinal Fluid (CSF) genotype and tropism; and (iii) measure concentration of antiretroviral agents. When indicated from the CSF analysis, a personalized change in ARV will be implemented. Cognition will be measured in all at study entry and 6 months later.
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
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.
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.
In this project the investigators develop and test a short message service (SMS) intervention based on the Information Motivation and Behavior skills (IMB) model. Reminding Adolescents To Adhere (RATA) prompts youths at two clinics in Uganda to take their medications and offers social support via weekly text messages. The investigators propose to adapt their previous successful SMS-intervention to the specific needs of youths and to evaluate the relative effectiveness of one-way versus two-way text messages (where two-way messages allow youths to respond to messages and we hypothesize that this may increase perceived social support that may be important for youth populations). We will also test the effectiveness of SMS messages over the longer-term (2 years), for which currently no information is available.
This is a pilot clinical trial of hematopoietic stem cell transplantation for patients with a diagnosis of Severe Combined Immune Deficiency (SCID) who do not have an HLA-matched sibling donor. The stem cells will be derived from a 1) matched unrelated donor (MUD), 2) unrelated cord blood donor, or 3) a haplo-identical (parental) donor (in descending order of preference).Patients will receive a novel conditioning regimen with Busulfan, Fludarabine and Anti-thymocyte globulin (ATG) followed by an unrelated donor hematopoietic stem cell transplant (HSCT) with T-cell depletion using the CliniMACS device.
ASIS Corporation (ASIS) has developed the only automatic injection system for delivery of injectable products to it's optimum/right spot, just outside of the fascia, which exists subdermally (between the skin and muscle). Bloodless basically implies longer lasting medicinal effects, and minimal side effects - advantages that reflect the NIH mission of enhancing health, lengthening life, and reducing the burdens of illness and disability. ASIS device is stabilized on the surface of the skin with negative pressure and emits an electrical current to create a bloodless cavity subdermally. ASIS device correctly, automatically, and consistently delivers therapeutic agents, yet requiring little skill of a practitioner - providing the steady and safe infusion into subdermal bloodless space of virtually any injectable product in addition to Botox, including GAMMAGARD LIQUID, Enbrel, Insulin, and Fillers, etc. According to the FDA, "This innovation will have major impact on the healthcare industry."
