Effectiveness of an Integrated Treatment to Address Smoking Cessation and Anxiety/ Depression in...

Human Immunodeficiency VirusSmoking Cessation6 more

Smokers living with HIV represent a major health disparity population in the United States and the world more generally. Major contributing factors to the maintenance and relapse of smoking among smokers living with HIV include increased exposure to multiple stressors associated with HIV, which often exacerbates anxiety/depression. In a previous project, the feasibility, acceptability, and initial efficacy of a 9-session, cognitive-behavioral-based intervention to address smoking cessation by reducing anxiety and depression via specific emotional vulnerabilities (anxiety sensitivity, distress tolerance, and anhedonia) was tested against an enhanced standard of care in a pilot randomized controlled trial (NCT01393301). It was found that when compared to a brief enhanced treatment as usual control, patients in the intervention achieved higher short-term and long-term smoking abstinence rates. In this project, the investigators seek to test this same intervention in a fully powered, 3-arm efficacy/effectiveness trial. The goal of this study is to randomize 180 smokers across three sites to test the efficacy/effectiveness of the intervention at increasing point prevalence abstinence by reducing anxiety and depression at a 1-month follow-up (the end of treatment timepoint/ approximately 1-month post quit day) and a 6-month follow-up (approximately 6-months post quit day).

Vedolizumab Treatment in Antiretroviral Drug Treated Chronic HIV Infection

HIV-infection/AIDS

Background: In nearly all people with human immunodeficiency virus (HIV) infection, immunity cannot either control or eradicate the infection. There are good medicinal treatments, collectively called "ART" (antiretroviral therapy) which control HIV infection by suppressing the virus in the bloodstream. ART is needed for life, and if a person stops taking ART the HIV infection returns in the bloodstream. So, there is good treatment, but no cure. The researchers want to test whether a period of treatment with vedolizumab can be used to control HIV infection in the bloodstream in persons with HIV on ART, after stopping ART. Objective: To determine whether vedolizumab is safe and tolerable in people with HIV, to assess the safety of an analytical treatment interruption (ATI), and to determine whether vedolizumab can control HIV infection in the bloodstream without the use of ART. Eligibility: Adults 18-65 with HIV who are being treated with ART Design: Participants will be screened with: Physical exam, medical history, blood and urine tests Participants will have a baseline visit which will include repeat of the screening testing. Participants will then present for their first study visit which will include: receiving vedolizumab infusions through an arm vein, repeats of the baseline testing. Participants will then have serial visits on a pre-specific schedule to receive ongoing vedolizumab doses every 2-4 weeks until week 20. Each visit will also include repeat of the baseline tests. After week 6 and before week 7 patients will discontinue ART. After the final infusion of vedolizumab at week 20 patients will continue to be assessed with physical exam, medical history, and repeat of the baseline testing every 4 weeks up to 1 year. ART will be re-started for participants if the level of HIV in the blood becomes too high, persists for too long, or if the CD4 count decreases by too much.

A Single Dose of Pembrolizumab in HIV-Infected People

Human Immunodeficiency Virus

Background: Human immunodeficiency virus (HIV) attacks the immune system. Some people with HIV have a low CD4+ T-cell count despite taking antiviral medicines that control HIV replication. These cells fight disease, so a low count makes it easier for people to become sick. Researchers want to see if a new drug can improve the immune system, including T cells. The drug is called pembrolizumab Objective: To see if pembrolizumab is safe to use in people with HIV who have a low CD4+ T cell count despite taking medcines that control HIV replication, and to see if it strengthens the immune system. Eligibility: People age 18 years or older with HIV who are taking antiretroviral drugs as treatment, have blood HIV levels below detection limits of commercial assays, and have a low CD4+ T-cell count (below 350 cells/mm3). Design: Participants will be screened with: Medical history Physical exam Heart, blood, and urine tests Sexually active participants must use 2 kinds of birth control. Participants will have leukapheresis. Blood will be removed through a needle in one arm. A machine will remove white blood cells. The rest of the blood will be returned into the other arm. Participants will have a baseline visit. They will have blood tests. They may have a pregnancy test. A needle will insert a thin plastic tube (IV) into an arm vein. The participants will get the study drug or a placebo through the IV for 30 minutes. They will be watched for a couple hours after. Participants will have 11 follow-up visits over the next 48 weeks. They will have a physical exam, vital signs, medical review, and blood tests. Participants may have another leukapheresis. Participants will be called every 12 weeks after their last follow-up visit to talk about how they feel and their health. Participation ends after the week 96 phone call. ...

MK-8527 Single-Dose Trial in HIV-1 Infected Participants (MK-8527-004)

Human Immunodeficiency Virus

This is a single-dose clinical study to evaluate the safety, tolerability, pharmacokinetics, and anti-retroviral activity of MK-8527 in antiretroviral therapy (ART)-naïve participants with human immunodeficiency virus type 1 (HIV-1) infection. The primary hypothesis is that, at a dose that is safe and generally well tolerated, MK-8527 will have antiretroviral activity as measured by a reduction from baseline in plasma HIV-1 ribonucleic acid (RNA) of ≥1.0 log10 copies/mL.

Combined Injectable Treatment for HIV and OUD

Human Immunodeficiency VirusOpioid Use Disorder

This is a one-year study that seeks to evaluate perspectives of combined injectable treatment for HIV and OUD. Specifically, with the development of new long-acting medications such as cabotegravir co-administered with rilpivirine (CAB/RPV) and extended-release buprenorphine (XR-B) there is a need to better understand factors that influence the delivery and uptake of this type of treatment. Therefore, this study will conduct qualitative (1:1) interviews with 32-45 key stakeholders to assess interest, knowledge, attitudes, barriers, and facilitators to integrated injectable treatment. Our team will utilize qualitative findings to inform clinical strategies to promote uptake and maintenance of long-acting injectable medications for HIV and OUD.

A Pragmatic Trial With Optimized Dose of Rifampicin and Moxifloxacin for the Treatment of Drug Susceptible...

TuberculosisHuman Immunodeficiency Virus

Tuberculosis (TB) remains a major global public health problem, particularly in low- and middle-income countries (LMICs) in Africa, Asia, and Eastern Europe. Approximately 10 million people fall sick with TB, causing up to 2 million deaths, worldwide per year. Considerable progress was made in TB control from 1990-2015, motivating the World Health Organization (WHO) to launch an ambitious EndTB strategy. However, the effect of the ongoing Coronavirus Disease 2019 (Covid-19) pandemic has been devastating and the last two years have seen the first year-on-year increases (of 5.6%) in TB mortality since 2005 . In order to regain lost ground, and re-establish progress towards elimination of TB, innovation is needed in all aspects of TB control, including development of shorter treatment regimens for drug susceptible (DS) and multi-drug resistant / rifampicin resistant (MDR/RR) forms of the disease. This protocol seeks to conduct the TB clinical trial combining the 8-methoxyfluroquinolone and optimised dose of rifamycing to address two questions. The first is to confirm the non-inferiority of a four-month optimised dose rifamycin and moxifloxacin-based regimen amongst African TB patient populations with high rates of co-incident HIV. Secondly, we seek to establish that the rifamycin of choice in potent 4-month anti-TB treatments could be rifampicin as this will be more rapidly up-scalable for public health impact.
