There are about 26 clinical studies being (or have been) conducted in Liberia. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Last Mile Health (LMH) has partnered with the Liberian Ministry of Health (MOH) to support the design and implementation of the National Community Health Assistant Program (NCHAP). In collaboration with MOH, LMH is planning to conduct an impact evaluation in Grand Bassa to assess the effect of the National Community Health Assistant Program (NCHAP) on health outcomes, as well as to learn lessons around program operations and implementation. Our central hypothesis is that Community Health Assistants (CHAs) within the NCHAP will reduce under 5 mortality, as a result of expanding access to and uptake of health care utilization in remote communities. We will use a mixed effects discrete survival model, taking advantage of the staggered program implementation in Grand Bassa districts over a period of 4 years to compare the incidence of under-5 child mortality between the pre- and post-CHW program implementation periods.
InVITE is funded by NIAID and is conducted in multiple international sites (approximately 20 sites across 7 countries). This is a study of adults who receive locally available COVID-19 vaccines through local vaccination programs. Persons will be enrolled within one day (before or after) of receipt of a COVID-19 vaccine. The study will enroll participants who receive COVID-19 vaccination at local clinics and/or study sites.
Background: Tuberculosis (TB) is a health threat for people living with human immunodeficiency virus (HIV). People living with HIV are more likely than others to develop active TB. Also, TB makes HIV progress faster. TB is a leading cause of death among people in the West African country of Liberia. Researchers want to find an effective testing method for latent tuberculosis infection (LTBI) to help people living with HIV in Liberia. Objective: To compare the interferon-gamma release assay (IGRA) and tuberculin skin test (TST) as LTBI screening tests in people living with HIV in Liberia. Eligibility: People ages 18 and older who take part in NIH study #19-I-N014 and are scheduled to have or have had IGRA at a Month 12 HONOR study visit. Design: Participants will be screened with a medical history and physical exam. Their medical records and HONOR study records will be reviewed. Participants will have TST. Purified protein derivative will be placed in the skin of their forearm. They will be observed for adverse reactions for 15 minutes. Between 48 and 72 hours after placement, they will have a second study visit to have the TST read. If they miss this time frame, they can return up to 7 days after placement. If they have a positive test result, they will have a chest x-ray. They will have a third study visit to review the results of the chest x-ray. They will be referred for clinical care if needed. They will take a pregnancy test if needed. Participation will last from 2 days to 6 weeks.
A Phase 1 Randomized, Double-blinded, Placebo-controlled, Dose-escalation Clinical Trial to Evaluate the Safety and Immunogenicity of rVSV∆G-LASV-GPC Vaccine in Adults in Good General Health
Background: Malaria is a disease that affects many people in Liberia. It is caused by germs (parasites) that are spread by mosquito bites. Researchers want to gather data that may help them understand the best way to use a malaria vaccine in Liberia, which will be important in getting rid of the disease. Objective: To find out how often people of all ages who live in Fleh-la and Marshansue, Liberia, get malaria. Eligibility: Healthy people ages 6 months and older who live in Fleh-la and Marshansue in a household with adults and children. Design: Participants will be screened with a physical exam and questions about their health. Participants will have monthly study visits. They will be asked about any symptoms of malaria and their use of bednets. Their vital signs, such as blood pressure and temperature, will be checked. Blood will be taken from the participant s arm or finger with a needle. If they have a fever, they will get a malaria test. If positive, they will get drugs to treat malaria. Once a month, participants houses will be examined for mosquitoes. The team will remove all mosquitoes they collect. As part of this collection, participants houses will be sprayed with a chemical to kill mosquitoes and other insects. Participants will not be allowed in their house while the team is inside. The spray will not harm the participants. Once a year, at the monthly visit, an additional blood sample will be taken. Some of the participants blood samples will be used for genetic testing. Participation will last for up to 3 years....
The investigators aim to evaluate the efficacy of a cash transfer and nutrition education program delivered by community health assistants to increase dietary diversity among children 6 to 23 months of age in Grand Gedeh County, Liberia.
Girl Empower (GE) is a program designed to equip girls with the skills and experiences necessary to make healthy, strategic life choices and to stay safe from sexual exploitation and abuse.
Background: There are many people living with human immunodeficiency virus (HIV) infection in Liberia. Most experts consider HIV an epidemic there. Researchers want to collect health data from Liberians with HIV over several years. This may help HIV prevention and treatment programs in Liberia. Objective: To learn more about how HIV affects people in Liberia. Eligibility: People with HIV in Liberia Design: Participants will be screened with a blood sample. Participants will visit the study clinic about 10 times over 3 years. They will need to return to the clinic after some visits to get test results. The visits will be closer together during the first part of the study and less frequent later. At each study visit, participants will: - Have a brief physical exam - Answer questions about how they are feeling and what medicines they are taking - Have blood taken from an arm vein by a needle - Give urine samples Participants ages 12 years or older may be asked questions about HIV risk behaviors. These include sex practices and drug use. Participants ages 18 years or older may be asked how their HIV infection makes them feel emotionally. Participants may be asked to join a research substudy. This will be about tuberculosis (TB) testing in people with HIV. For this substudy, participants will have a TB skin test. A small amount of liquid will be injected under the skin on the arm. Participants will return to the clinic a few days later. The test area will be checked. They will get their test results.
Background: The disease malaria affects many people in Liberia and other parts of Africa. It is caused by germs that are spread by mosquito bites. It may be mild but can be serious or can lead to death if not diagnosed and treated. Children younger than 5 years old and pregnant women are most at risk of malaria. Worms also infect many people in Liberia. They can be caused by mosquito bites or by touching soil or still water. Worm infections can be mild or serious. Doctors in Liberia and their NIH partners want to learn more about these diseases in women and children. Objective: To measure how much malaria and worm infections there are in pregnant women and children in two counties of Liberia. Eligibility: Pregnant women ages 18 and older and children ages 6 12 months seeking routine care at C.H. Rennie Hospital or the Duport Road Health Center Design: Participants will be screened with questions about their health or their child s health. Participants will be asked further questions about their health and about their home life. Participants will give a small amount of blood by finger prick. This will be tested to see if they have malaria or some types of worms, and for research studies. Participants who are sick from malaria will be treated at a study clinic. Treatment will follow standards of the Liberia and/or the World Health Organization.
Appropriate targeting of interventions for neglected tropical diseases (NTDs) that require innovative and intensified disease management (IDM) requires accurate data on the distribution of these diseases within endemic countries. In most instances however, existing case register data generated through national health management information systems or during programmatic activities do not provide an accurate representation of the true burden of IDM NTDs. This study will pilot a cluster randomized screening and confirmation survey to estimate the burden of IDM NTDs characterised by skin conditions associated with long-term disfigurement and disability. These include: leprosy, Buruli ulcer, yaws and lymphoedema and hydrocele resulting from lymphatic filariasis. The survey is being conducted in one county in Liberia. The protocol involves community-level screening by community health volunteers trained to use photo-based visual aids to recognise changes in the skin that broadly indicates patent infection. All suspected cases will be verified in their homes by local and national experts trained in the diagnosis of skin-presenting NTDs. The survey will generate accurate district-level prevalence estimates of leprosy, yaws, Buruli ulcer and lymphatic filariasis-associated lymphoedema and hydrocele and quantify the total costs and cost per case detected. In addition, results from this protocol will be compared with routinely collected case register data, to better understand how health system records reflect the true disease situation on the ground and quantify unmet need.
