655 Clinical Trials for Various Conditions
The goals of this clinical study are to look at how lenacapavir (LEN) passes through the body and to assess the safety of LEN and emtricitabine/tenofovir disoproxil fumarate (F/TDF) for pre-exposure prophylaxis (PrEP) in people who inject drugs (PWID) in the United States (US). The primary objectives of this study are to characterize the pharmacokinetics (PK) of LEN and to evaluate the safety of LEN and F/TDF for PrEP in US PWID.
The goal of this clinical study is to look at how lenacapavir (LEN) passes through the body and to assess the safety of LEN and emtricitabine/tenofovir disoproxil fumarate (F/TDF) for prevention of HIV in the cisgender women in the US. The primary objectives of this study are: 1) to characterize the pharmacokinetics (PK) of LEN in United States (US) cisgender women; 2) to evaluate the safety of LEN and F/TDF for pre-exposure prophylaxis (PrEP) in US cisgender women; and 3) to evaluate the general acceptability of LEN injections and oral F/TDF in US cisgender women.
This study will establish the minimum safety, tolerability and acceptability data needed to support the use of cabotegravir long-acting injection (CAB LA) in an adolescent population, potentially transforming the field of HIV prevention for young people.
During the formative research phase, investigators will undertake formative studies to locate, understand, and characterize high-risk social networks of African American MSM in the community; gain community participation, involvement, and input; and undertake interviews with key informants and community members to gain information needed to pilot test study recruitment procedures, measures, and intervention content. During a 4-year main outcome trial phase, the investigators will enroll 24 separate sociocentric ("bounded") social networks composed predominantly of Black MSM. Each sociocentric network will consist of the ring of friends surrounding an initial high-risk index as well as all friends surrounding persons in this second ring and then friends surrounding a successive third snowball ring of enrollees. Each 3-ring sociocentric network is expected to consist of approximately 40 unique members (n=24 networks, each with 40 members = approximately 960 individual participants). All participants will be assessed at baseline to measure sexual practices, substance use, and other risk characteristics over the past 3 months; asked to provide biological specimens to be tested for HIV and other sexually transmitted diseases (STDs); and counseled in HIV/STD risk reduction. STDs will be treated and those with HIV will be referred for treatment. The investigators will identify the individuals in intervention condition networks with the greatest number of reciprocal interconnections and the most favorable sociometric standing in the network. These individuals--expected to constitute approximately 20% of the sociocentric network and designated as network leaders--will be recruited to attend a 9-session program that provides training and guidance in how to deliver on-going, theoretically-based, and culturally tailored risk reduction advice and counseling to other members within the same network. Six and 18 months following the intervention, all participants will be reassessed on risk behavior and STD/HIV laboratory measures as well as measures of intervention exposure, with positive STD and HIV cases respectively treated or referred to care at each assessment point. Outcome analyses will test whether there is greater reduction in high-risk sexual practices, substance use associated with risky sex, and HIV/STD incidence within social networks in the intervention condition. The primary trial endpoints are reductions in prevalence and frequency of unprotected anal intercourse with nonexclusive partners, increased condom use, and lower incidence on a composite biological measure of new HIV/STD disease during the followup period.
This study will determine the safety and side effects of two experimental HIV vaccines given in a "prime-boost" schedule. It will also monitor participants for the social impact of being in an HIV vaccine study (e.g., problems with insurance, health care, friends, family, employment, housing, and so forth). The vaccines are VRC-HIVDNA016-00-VP (called the DNA vaccine) and VRC-HIVADV014-00-VP (called the rAd vaccine). The DNA vaccine codes for four HIV proteins. The rAd vaccine is made using an adenovirus (a common virus that causes upper respiratory infections, such as the common cold) that has been modified to contain DNA that codes for three HIV proteins. These vaccines cannot cause HIV or adenoviral infections. The study will also see if the vaccines cause an immune response; if the injection of the DNA vaccine given using a needle and syringe is similar in safety and immune response to giving them with a needleless injection device called a Biojector 2000; if people who already have antibodies to adenovirus still have an immune response to rAd vaccine; and if there are social harms that result from participating in an HIV vaccine study. Healthy volunteers between 18 and 50 years of age may be eligible for this 42-week study. Candidates are screened with a medical history, physical examination, blood and urine tests (including pregnancy test for women), and questions regarding sexual behavior and other practices. Participants receive three injections (shots) of the DNA vaccine and one injection of the rAd vaccine. All injections are given into a muscle in the upper arm (alternating right and left arms with each injection), using a needle and syringe or the needleless Biojector 2000. The first vaccination is given the day of enrollment into the study, and the DNA vaccinations are given about 4 weeks apart from each other, with a minimum of 21 days between injections. The rAd "booster"vaccination is given at Week 24. Participants fill out a diary card at home for 5 days after each vaccination, recording their temperature and any symptoms. They come to the clinic for follow-up 3 days each DNA vaccine injection, and call or return again 7 days after each injection. They call a study nurse 1 or 2 days after the rAd injection. There are 15 to 18 clinic visits during the course of the study. At each visit, participants are checked for health changes or problems. Blood and urine samples are collected at some visits. Participants are periodically tested for HIV and asked questions about their sexual behavior and drug use and are counseled throughout the study on HIV risk reduction. They are also asked about any social effects they may have experienced as a result of their participation in this study.
The purpose of this study is to find the best strength of chlorhexidine (a solution that kills germs), for washing the mother's vagina during labor and the newborn baby, that may reduce the chance of HIV being passed from an HIV-positive mother to the baby. When used as a wash on the vagina during labor, and on a newborn shortly after birth, a higher dose of chlorhexidine is more likely to reduce the rate of HIV-1 transmission from mother to baby. Laboratory tests suggest that a higher dose of chlorhexidine will be more effective in killing HIV.
To evaluate the safety and effectiveness of Retrovir (AZT) when used as prophylaxis for health care workers at risk for HIV infection from exposure to HIV-contaminated blood or blood components.
To prevent individuals who have had a massive accidental exposure to HIV from becoming infected with HIV and possibly developing AIDS, by treating them with zidovudine (AZT). Although the number of persons who have been (or will be) exposed to a high concentration of HIV is quite small, these persons have a high risk of becoming infected and treatments are needed to prevent infection after such an exposure. In animal studies, AZT has prevented the development of infections after exposure of the animals to a retrovirus (the HIV is a retrovirus). In patients with AIDS, AZT has been effective in delaying the progression of the disease. For these reasons a trial of AZT is indicated.
This study is designed to find out whether HIV-positive patients whose immune systems have improved after receiving anti-HIV treatment should take azithromycin to prevent Mycobacterium avium complex (MAC) disease. This study also examines the possibility of putting off MAC prevention treatment in patients who respond well to anti-HIV drug therapy. Azithromycin is approved for the prevention of MAC disease in people with HIV and low CD4 cell counts. However, some people who have taken azithromycin have been found to carry antibiotic-resistant bacteria (germs that can grow despite the presence of drugs used to kill them). It is not known whether the risks associated with taking azithromycin outweigh the risk of getting MAC disease.
The purpose of this study is to see if giving the anti-HIV drug nevirapine (NVP) to HIV-positive pregnant women and their babies can help reduce the chance that a mother will give HIV to her baby during delivery. This study will also test the safety of the drug and see how well it is tolerated by the mother and her baby. Previous studies suggest that NVP is a promising medication for blocking HIV transmission from HIV-positive mothers to their babies.
In response to the increasing rates of HIV/STD infections among women over the age of 50, especially minority women, and in the attempt to reduce HIV/STD risks for over ten million older adult American women who are impacted by gray divorce and at risk for unsafe sex, the investigators will create, test, and commercialize a novel positive psychology-based "SmartWeb" intervention to promote wellbeing, HIV/STD awareness, and safe sex practices among culturally-diverse older divorced or separated women who are dating. This large end-user market for the proposed HIV/STD risk reduction intervention will greatly facilitate commercialization through advertisements, marketing research based on data mining, and in collaboration with manufacturers of condoms, and other large companies offering health products and services to older women.
The present study includes a randomized clinical trial of a peer health education intervention and a 12-month longitudinal study. The sample will include Black Men who have Sex with Men (MSM) who will be randomized into an experimental or control condition and then asked to recruit peer and risk network members for HIV testing over a 3 month period. Some of the network members who are recruited for voluntary counseling and testing (VCT) will enroll into the longitudinal study for assessments only. Both index and network participants will be assessed at baseline, 6, and 12-months. The specific aims of the proposed study are to: 1. Train Black MSM (index participants in the experimental condition) to conduct peer health education, to promote VCT and HIV risk reduction among social network members, and to recruit social network members for VCT. 2. Examine changes in HIV risk behaviors and VCT among index participants and their network members in the experimental intervention as compared to those in the control condition. 3. Examine mediating effects of social environments (networks, social norms) on HIV risk behaviors and VCT, among indexes and network members. 4. Examine mediating effects of individual level factors (substance use and depression) on HIV risk behaviors and VCT among indexes and network members.
In this study, investigators propose to randomize 165 human immunodeficiency virus positive patients to one of three 16-week treatment conditions: (1) standard care; (2) standard care + cell phone-based adherence reminders; or (3) standard care + cell phone-based adherence reminders and contingency management. In this latter condition, patients will earn reinforcement for sending in time- and date-stamped self videos of antiretroviral therapy medication ingestion. Primary outcomes will include viral loads and self-report measures of adherence, and effects will be evaluated both during the treatment period and throughout a one-year follow-up. Investigators hypothesize that the cell phone reminder condition will improve adherence relative to standard care, and the cell phone reminder plus contingency management condition will have the best outcomes. Results from this study may have widespread implications for the use of cell phones as a novel technology to improve initial adherence to antiretroviral therapy, thereby reducing the spread of drug resistant human immunodeficiency virus strains to the community.
The goal of this clinical study is to test how well the study drug, lenacapavir (LEN), works in preventing the risk of HIV.
The primary objective of this study is to assess the rates of HIV-1 infection in Men (MSM) and transgender women (TGW) who have sex with men and who are administered daily emtricitabine/tenofovir alafenamide (F/TAF) or emtricitabine/tenofovir disoproxil fumarate (F/TDF) with a minimum follow-up of 48 weeks and at least 50% of participants have 96 weeks of follow-up after randomization.
Background: Antibodies help the body fight infection. VRC01LS is an antibody directed against HIV virus. HIV attacks the immune system. In animals, VRC01LS inactivated many types of HIV viruses. Researchers want to see if it does this in people. Objectives: To see if VRC01LS is safe and well-tolerated in people. To see what level of VRC01LS is maintained in people and if they develop an immune response to it. Eligibility: Healthy people ages 18 to 50 Design: Participants will be screened in protocol number VRC 500 (NIH 11-I-0164) with medical history, physical exam, and blood and urine tests. The study will last 24 to 48 weeks. Visits will last 2 to 8 hours. Participants will get VRC01LS through either: * A needle in an arm vein or * A small needle placed into the fatty tissue under the skin of the abdomen, thigh, or arm. Participants will be assigned to 1 of 6 groups. Groups 1 to 4 will get 1 dose of VRC01LS. They will have follow-up visits through week 24. Groups 5 and 6 will get 1 dose of VRC01LS every 12 weeks (3 doses). They will have 4 to 5 visits between the second and third dose, and follow-up visits through week 48. Participants will have 1 to 3 follow-up visits in the week after receiving VRC01LS. They will record their temperature and keep a diary of symptoms for 3 days after a dose. They may have additional unscheduled visits. At each visit, participants will have a physical exam and may have blood and urine tests.
This is a prospective, 3-year observational study to describe drug utilization in uninfected individuals (UIs) who initiate emtricitabine (FTC)/tenofovir disoproxil fumarate (TDF) (Truvada®) for a pre-exposure prophylaxis (PrEP) indication. An electronic source of pharmacy/medical encounter information will be used to assess the demographics and other characteristics of the subjects prescribed FTC/TDF or its components in a prospective fashion. The data provider will supply all the de-identified information regarding each visit/interaction that the subject has had with the health system and all the diagnoses and medications that the UI has had prospectively and retrospectively for the length of time captured by the source selected. 200 physicians who prescribe FTC/TDF for a PrEP indication will be sampled from the same source.
This is a five-part study that will take place in the Bronx, New York (NY), and Washington, District of Columbia (DC). The different components of the study will focus on increasing the number of people being tested for HIV, evaluating ways to link HIV-infected people to HIV care sites, evaluating methods to reinforce antiretroviral therapy (ART) adherence, and evaluating a counseling program that focuses on HIV prevention. (Details for only three components of this study are included in ClinicalTrials.gov (Linkage-to-Care, Viral Suppression and Prevention for Positives) because they are the only ones that were randomized and had prescriptive interventions.)
SHAG is a text messaging-based HIV prevention program designed for cisgender sexual minority boys and men 13-20 years of age across the United States. Investigators will test it against a control group that receives messages about healthy lifestyle.
The goal of this clinical trial is to test the efficacy of a mobile app, Combine, to increase the uptake of HIV and STI testing and pre-exposure prophylaxis (PrEP) over 24 months and to assess the effects of different implementation strategies on intervention maintenance among GBMSM in rural southern United States. The main aims of the study are: * To assess the relative effects of three treatment conditions on gains in engagement in HIV prevention compared to a modified standard of care control condition * Measure and assess secondary factors affecting app implementation * Refine implementation strategies and coordinate with potential funders Participants will download an HIV prevention smartphone app and be randomly assigned to one of four groups: * Control: App access only * Self-testing: App access + ability to order HIV and STI self-test kits * Motivational interview: App access + motivational interview to develop plans to use app effectively. * Self-testing + motivational interview: App access + ability to order HIV and STI self-test kits + motivational interview to develop plans to use app effectively. Researchers will compare each of the latter three groups to the control condition to see if HIV and STI testing increase in these groups
The goal of this clinical trial is to evaluate the effectiveness of a social network intervention to recruit people who inject drugs and their networks for HIV testing and linkage to HIV prevention and treatment services in Maryland. Study aims are to determine the effectiveness of a social network driven intervention to increase: * HIV testing (primary); * PrEP knowledge; * Uptake of HIV services and pre-exposure prophylaxis (PrEP); * Uptake of medication for opioid use disorder (MOUD) initiation. Eligible participants who access syringe service programs (SSPs) serving two counties in Maryland and their risk network members (NMs) will be recruited using an established network inventory and coupon recruitment method. When an index successfully recruits NMs, the index-NM cluster will be randomized to either a peer-educator intervention arm or an equal-attention control arm. Index participants randomized to the peer-educator intervention arm will complete a training program adapted with stakeholder input to context that emphasizes effective communication, frequent HIV testing, and awareness of evidence-based HIV prevention and treatment services. An important innovation to the network intervention will be training indexes to use and distribute HIV self-test kits and naloxone to their NMs. Index participants randomized to the equal-attention control arm will receive training sessions focused on the opioid overdose epidemic and will not include any training to serve as a peer educator. All participants (indexes and NMs) will complete study assessments at baseline and at 3 and 9 months. We will compare the peer-educator intervention group and the equal-attention control group on rates of HIV testing, knowledge of PrEP options and resources, and rates of initiation of HIV treatment, PrEP, and MOUD treatment since the previous assessment (past 3 or 6 months).
The purpose of this study is to determine whether Motivating Youth to Reduce Infections, Disconnections, and Emotion dysregulation (MY-RIDE) decreases substance use , to determine whether MY-RIDE increases human immunodeficiency virus (HIV) prevention strategies and to evaluate MY-RIDE effects on willingness to take Pre-Exposure Prophylaxis (PrEP), stress, substance use urge, and use of mental health and substance use services when compared to attention control youth
The goal of this pilot randomized controlled trial is to assess the feasibility, acceptability, and preliminary impact of the mHeaLth interventiOn To redUce Stigma (LOTUS) intervention to improve HIV prevention service engagement and reduce intersectional stigma among racially diverse women who use drugs. LOTUS is a technology-delivered intervention that provides HIV prevention informational content and tips, peer social support and social networking features, a resource locator, HIV prevention monitoring and reminders (e.g., reminders for HIV/STI testing and PrEP doses), and virtual guided discussions with health care professionals.
Latinas continue to be affected disproportionally by HIV in the United States (US). Often, Latinas are not aware of their HIV status. Also, their perception of low risk for HIV interferes with condom use, HIV testing and lack of awareness, access, and use of Pre-exposure Prophylaxis \[PrEP\]. About 60% of total HIV cases in NC occur among women of childbearing age, thus vulnerability to HIV is particularly acute among Latinas between ages 18 and 44 years old, an age group with the highest rate of new HIV infections in NC. These disparities indicate that HIV prevention among Latinas is urgent; therefore, the investigators propose an innovative intervention - a filmed dramatized story (telenovela/soap opera) Infección de Amor \[IA\] (Love Infection) - culturally tailored for Latinas in the US and delivered online. Infección de Amor was filmed and developed but has not been tested with the target audience. The proposed study will pilot test IA and move the intervention to online using a website that will allow individual access around the clock from any location and device, such as a smartphone, ensuring wide dissemination of the intervention in the future. This is a a two-year planning grant (R34) to prepare for an R01 efficacy trial. The aims are to: 1) Develop the intervention delivery website, conduct a website usability test, and test the feasibility and acceptability of the IA intervention (four telenovela episodes) with 10 Latinas, 2) Conduct a randomized controlled pilot study to examine change in HIV prevention behaviors (condom use; HIV testing; and PrEP awareness, access, and use) comparing 71 intervention and 71 control Latinas from baseline (Time 1 \[T1\], 0 months) to post-active intervention (Time 2 \[T2\], 1 month), and to six months follow-up, a period with no contact from the study staff (Time 3 \[T3, 7 months\]), and 3) Complete establishing the study infrastructure, expanding the multidisciplinary team, building the research partnerships with the community, finalize the protocol and training materials, refine recruitment and retention strategies, data collection and data management procedures, and obtain institutional review board approval in preparation for an R01 efficacy study. This study address the National Institute on Drug Abuse (NIDA) goal #4: increase NIDA research and programs' public impact. This is a novel intervention to advance HIV prevention for Latinas. This study implement a culturally durable and feasible intervention for Latinas.
This is a community-engaged research project that aims to identify and pilot test interventions that may reduce substance use stigma among professionals at primary care sites serving patients who might be exposed to HIV or are living with HIV. Our goal is to develop a multi-level substance use stigma intervention that leverages 1) education and 2) organizational policy to address structural drivers of stigma and the stigmatizing professional attitudes and behaviors that affect patients. Hypothesis: the results of the trial pilot research and are expected to provide scientific evidence demonstrating feasible and potentially effective substance use stigma reduction interventions that go beyond simple individual-level professional training. We plan to build on the data from this pilot trial study to then further test the multi-level intervention in another larger trial study with primary care organizations to determine whether the intervention addresses multiple complex drivers of substance use stigma that influence HIV prevention and care outcomes among people who use drugs.
This digital couples-based HIV/STI prevention intervention project will determine preliminary efficacy to improve uptake of evidence-based strategies and a tailored prevention plan among cisgender male couples who are in a relationship (defined as greater than 3 months or more).
The goal of this pilot study is to gather and analyze qualitative data from focus groups with Transgender men who have sex with men (TMSM) to learn more about the life experiences unique to TMSM that influence their attitudes and beliefs about HIV risk, as well as to better understand the intersections of these specific sexual and gender identities.
The purpose of this study is to develop and test a serious injection-related injections (SIRI) checklist aimed at increasing evidence-based treatment for rural people who use drugs (PWUD) including innovative, long-acting injectable agents. The central hypothesis is that hospital-based care models can successfully engage rural and Southern (PWUD) in effective addiction treatment and infection prevention. The activities in this study will be foundational to Ending the HIV epidemic in rural states.
Purpose: To test the feasibility, acceptability of the IA intervention (four telenovela episodes), assessment of the mechanisms of action (self-efficacy, narrative engagement, and emotional elicitation) and conduct a randomized controlled pilot study to examine the change in primary outcomes (condom use, HIV testing, Pre-exposure Prophylaxis (PrEP) awareness and use) and secondary outcomes (Substance abuse (SA), intimate partner violence (IPV), and depression comparing 33 intervention- and 33 control Latinas at baseline (T1, pre-intervention), T2 (immediately post-intervention, 1 month) and T3 (3 months after the end of the intervention, with no intervening contact with study staff). Participants: 66 Latinas ages 18-44 years who report sexual activity with a man in the last 6 months, have internet access from any device, and reside in NC. Procedures (methods): Participants will be asked to: (1) receive an orientation about the use of the Infección de Amor (IA) telenovela website and access the telenovela website once a week for 4 weeks to watch a telenovela episode and answer some questions about the episode (half hour each week, 2 in total), (2) attend to a one hour-meeting with the research team to complete a baseline survey, (3) complete a survey (on their own) one-month after the baseline survey, and (4) complete another survey (on their own) 4-months after the baseline survey. Participants will complete a structured survey in the first meeting (baseline survey) with a member of the research team and then they will complete the follow-up surveys (1-month and 4-months after baseline) on their own. Participants can request help to complete these surveys with the help of the research team (online using Zoom or face to face if needed). The moment that participants will access the IA intervention will depend on the group to be assigned by the research team (intervention or control group).
HIV and Sexually Transmitted Infection (STI) rates are increasing in rural areas including rural Colorado. Many rural residents find it difficult to access HIV and STI prevention services. In this study, an online survey on HIV and STI Prevention and best practices to provide access to prevention will be administered to rural residents in three zip 3 zones in rural Colorado. In addition to the baseline survey, study participants who are interested and medically eligible may initiate PrEP services with the University of Colorado HIV Prevention Program and receive PrEP through telemedicine visits, mailed home lab kits, and mailed medication. Persistence in PrEP care, acceptability, and feasibility of telemedicine and home lab kits will be measured.
