There are about 53 clinical studies being (or have been) conducted in Sierra Leone. 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.
In Sierra Leone, poverty and challenges with family functioning can lead to family separation, and children may go to live on the street or enter residential care institutions/orphanages. Helping Children Worldwide (HCW), a non-profit organization with over 20 years of experience in Sierra Leone, has developed a two-part Family Strengthening Program delivered by their program partners in Sierra Leone, the Child Reintegration Centre, to improve families financial literacy and attachment between caregivers and children, with the ultimate goal of preventing family separation. The hypothesis of this study is that the Family Strengthening Program program is effective at (1) changing parenting behaviors, (2) improving emotional regulation, (3) improving caregiver-child attachment, and (4) improving financial literacy in dyads consisting of children ages 9-13 and their caregivers.

This is a Phase 2, open-label, study evaluating the safety and immunogenicity of the 2-dose vaccination regimen, Ad26.ZEBOV, MVA-BN-Filo, in adults and children originally enrolled in the control arm of the EBOVAC-Salone study
As efforts to control malaria are stalling, and the disease is particularly severe in children under the age of two, it is imperative for countries in sub-Saharan Africa, with areas of moderate-to-high transmissions, to implement Perennial Malaria Chemoprevention (PMC) delivered through the Expanded Program on Immunization (EPI), which is the only feasible, sustainable and cost-effective strategy to reach this high-risk group. PMC is a full therapeutic course of antimalarial medicine (with sulfadoxine-pyrimethamine, SP) delivered to infants in the context of routine immunisation services during the first two year of life. PMC has been shown to be safe, efficacious in reducing clinical malaria, anaemia and hospital admissions, and to be highly cost-effective; for all these reasons, the World Health Organization (WHO) recommended in 2010 Intermittent Preventive Treatment for Infants (IPTi) for malaria prevention. Only one African country - Sierra Leone -put IPTi into policy and practice. Concerned with this slow adoption, WHO in 2019 recommended adaptations be urgently tested through pilots assessing impact, operational feasibility and cost effectiveness. In 2022, WHO expanded that recommendation to cover children through the age of two because of studies documenting the value in children aged 12 to 24 months. The name for this preventive treatment has consequently changed to Perennial Malaria Chemoprevention (PMC) as the updated recommendation is no longer just for infants. MULTIPLY is the pilot implementation of PMC in selected districts in Mozambique, Sierra Leone and Togo to maximise the delivery and uptake of PMC, to achieve the full potential of this intervention. Working with the ministries of health in Mozambique, Sierra Leone and Togo, MULTIPLY will give up to 6 doses of PMC in the first two years of life. PMC will be given at health facilities and EPI mobile outreach clinics using a paediatric dispersible formulation of SP, alongside routine vaccinations and vitamin A supplementation.
The human monoclonal antibody (mAb), ansuvimab (mAb114), will be provided to Ebola-infected patients as either a treatment or as PEP under expanded access. Ansuvimab is administered at 50 mg/kg as a single intravenous (IV) infusion
Vaccine hesitancy is defined by the WHO's Strategic Advisory Group of Experts on Immunization as a 'delay in acceptance or refusal of vaccination despite availability of vaccination services'. This varies in form and intensity based on when and where it occurs and what vaccine is involved. Several prophylactic vaccines against COVID-19 are currently available. As the world is beginning the roll-out the first approved vaccines, little is known about people's potential acceptance of a COVID-19 vaccine in most of the African countries. ACHES (African COVID -19Vaccine Hesitancy) is an observational study aimed at measuring COVID-19 vaccine hesitancy in five west African countries and exploring causes behind the hesitancy with the main objective of informing guidelines for the proficient roll-out of the vaccines in the region.
This is an open-label study evaluating the safety and immunogenicity of a booster dose of Ad26.ZEBOV administered to children who were previously vaccinated with Ad26.ZEBOV followed by MVA-BN-Filo 56 days later.
This study will pilot a family-focused, behavioral health intervention while also developing and piloting mHealth tools to support Community Health Workers (CHWs) in Sierra Leone. This dual focus will help build capacity both for delivery of evidence-based mental health services to reduce family violence and harsh parenting practices, and for effective use of mHealth strategies to improve healthcare delivery quality. This study will leverage Government of Sierra Leone investments in community health initiatives as a strategy to address critical healthcare workforce limitations that plague delivery of evidence-based interventions to vulnerable families in post-conflict Sierra Leone. Study aims are to: Aim 1. Employ a five-phase user-centered design approach to develop and test mHealth tools to improve training, supervision, and fidelity monitoring of Community Health Workers. Study investigators hypothesize that mHealth tools will be feasible, acceptable, and user-friendly. Aim 2. Conduct a Randomized Controlled Pilot Study to assess feasibility, acceptability, costs and preliminary effects of the mHealth-supported delivery of FSI-ECD on parent mental health, emotion regulation, and familial violence in high risk families with children aged 6-36 months (n=40) in comparison to control families (n=40) who receive standard care. Parental mental health, emotion regulation, household violence, and parenting practices will be assessed at baseline, post-intervention and 6-month follow-up. Study investigators hypothesize that (a) the effects of the FSI-ECD will be comparable to results observed with vulnerable families in Rwanda; (b) digital tools will be feasible and acceptable to CHWs and supervisors. Aim 3. Leverage well-established relationships and government partners to strengthen capacity for mHealth research and quality healthcare delivery in Sierra Leone. Partners include the University of Makeni, the Directorate of Science, Technology and Innovation, and the Ministry of Health and Sanitation.
Ready-to-use therapeutic food (RUTF) is the standard of care for the treatment of SAM. UNICEF requires that there be no oil separation in these products necessitating the use of emulsifiers. The effect of emulsifiers on gut health and integrity in children receiving an exclusive diet of RUTF is unknown. The PIs have recently completed a randomized, triple-blind, controlled, clinical equivalency trial in Sierra Leone comparing the alternative oat RUTF (oat-RUTF) to standard RUTF on recovery rates in children with SAM. This study demonstrated higher rates of recovery among children receiving the oat-RUTF. The investigators hypothesize that this benefit may be due to the lack of emulsifier in the oat-RUTF resulting in improved intestinal health.This research project is a double-blind, randomized, controlled clinical effectiveness trial comparing a novel RUTF containing oats and no emulsifier and standard RUTF on recovery from severe acute malnutrition (SAM) and effects on intestinal health. The trial will be conducted in up to 40 PHUs in Western Rural and Pujehun Districts where supplementary feeding programs (SFP) are not currently available.
Infectious diseases are among the most common causes of mortality in the over 2.5 million children under 5 years of age (U5) who died in 2018 in sub-Saharan Africa (SSA). New approaches to treatment and prevention of these diseases are needed to increase child survival. Sierra Leone has one of the highest rates of under-five child mortality in the world. It is estimated that 32,000 children die each year, the leading causes being neonatal conditions, malaria, pneumonia and diarrhea. In Sierra Leone, the available information on malaria indicates that it accounts for 38% of deaths among under-five children. Reducing the prevalence and impact of the disease among the general population is a major priority of the Ministry of Health and Sanitation (MoHS) of Sierra Leone . Intermittent Preventative Treatment in infants (IPTi) - the administration of a full course antimalarial treatment to infants at individual timepoints regardless of infection status- has been shown to reduce clinical malaria and anemia in infants in the first year of life . When delivered alongside the Expanded Program on Immunization (EPI), IPTi with Sulphadoxine-pyrimethamine (SP) is a highly cost-effective intervention. . Sierra Leone is currently the only country that implements nationwide the World Health Organization's (WHO) IPTi guideline, which is administered within the first year of life. However, its benefit when expanded into the second year of life remains unknown. Taking the advantage of the inclusion in the EPI program of a booster dose of measles vaccine at 15 months of age, the ICARIA trial will also assess the efficacy of adding a dose of IPTi-SP at this age. Recent studies show that azithromycin (AZi) - a macrolide antibiotic with some antimalarial effect- is associated with a significant reduction in childhood mortality when used in mass drug administration (MDA) for trachoma elimination in areas of sub-Saharan Africa (SSA) with child mortality rates far beyond Sustainable Development Goals , . However, despite the potential benefit of the intervention several fundamental scientific questions need to be answered before it can be recommended for large-scale implementation.
