There are about 247 clinical studies being (or have been) conducted in Ghana. 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.
This pilot study has 2 components: 1) a cross-sectional assessment designed to estimate the prevalence of anaemia leading to donor deferral, the prevalence of iron deficiency (ID) and iron deficiency anaemia (IDA) among first-time donors, and 2) a longitudinal 2-arm parallel groups trial among first- time voluntary donors that compares haemoglobin levels at 4 months among those with ID or IDA who receive iron supplementation to those without ID or IDA who do not receive iron supplementation. A structured questionnaire will be used to extract demographic characteristics. Participants will be followed for a total of 6 months with study visits at 2, 4 and 6 months after the baseline assessments. Blood draws for full blood count (FBC), peripheral film comment, malaria rapid diagnostic tests (RDT) and ferritin assessment will occur at baseline and all follow-up visits. In addition, we will use a qualitative approach to identify barriers and facilitators of blood donation and the use of dietary and iron supplementation strategies to address iron deficiency and/or anaemia. This will involve conducting focus group discussions during the last month of the intervention and key informant interviews. Expected Outcomes The expected outcomes of the study have been grouped into two, primary and secondary. Primary Outcome will be haemoglobin level after 4 months. Secondary Outcomes are A. Change in haemoglobin levels B. Diagnosis of ID or IDA at 4 months C. Serum ferritin concentration after 4 months of intervention D. Acceptability of iron supplementation among participants and stakeholders E. Incidence of gastrointestinal adverse events F. Incidence of suspected malaria or bacterial infections G. Incidence of ID and IDA H. Successful return (non-deferred) to the blood donor pool after intervention within 6 months of enrolment I. Key barriers and facilitators of intervention implementation.
Violence has severe and long-lasting negative consequences for children's and adolescents' well-being and psychosocial functioning, thereby also hampering communities' and societies' economic growth. Studies show high prevalence of violence by teachers against children in Sub-Saharan Africa, both in countries where violence is lawful as disciplinary measure at school and in countries where it has been officially banned. In addition to legal and structural factors (e. g. stressful working conditions for teachers), attitudes favoring violence against children as an effective and acceptable discipline method and the lack of access to alternative non-violent strategies are likely to contribute to teachers' ongoing use of violence against children. Notwithstanding, there are currently very few school-level interventions to reduce violence by teachers that a) have been scientifically evaluated and b) that focus both on changing attitudes towards violence and on equipping teachers with non-violent discipline strategies. Thus, the present study tests the effectiveness of the preventative intervention Interaction Competencies with Children - for Teachers (ICC-T) in primary and secondary schools in Tanzania, Uganda and Ghana. Previous studies have provided initial evidence on the feasibility and effectiveness of ICC-T to reduce teacher violence in primary and secondary schools in Tanzania and secondary schools in Uganda. This study aims to provide further evidence for the effectiveness of ICC-T to reduce violence and to improve children's functioning (i.e. mental health, well-being, academic performance) across educational settings, societies and cultures.
This Phase 3 study will assess the safety and efficacy of inclacumab, a P-selectin inhibitor, in reducing the frequency of vaso-occlusive crises (VOCs) in approximately 240 adult and adolescent participants (≥ 12 years of age) with sickle cell disease (SCD). Participants will be randomized to receive inclacumab or placebo.
The purpose of this Phase III study is to assess the efficacy, safety, and immunogenicity of two CoV2 preS dTM-AS03 vaccines (monovalent and bivalent) as part of primary series vaccinations in a multi-stage approach, as well as a booster injection of a CoV2 preS dTM-AS03 vaccine, in adults 18 years of age and older. A total of approximately 21 046 participants are planned to be enrolled (5080 per study intervention group in Stage 1 and 5443 per study intervention group in Stage 2). Initial, double-blind, primary series study design is planned for 365 days post-last Initial injection (ie, approximately 386 days total) for each participant. Based on decisions of the Study Oversight Group, Stage 1 and Stage 2 participants will be invited to participate in an unblinded Crossover / Booster study design with duration as follows: - For participants who initially received vaccine: 12 months post-booster (ie, approximately 18 to 24 months) - For participants who initially received placebo: ≥ 4 months post-last dose of the primary series + 12 months post-booster (ie, approximately 28 to 34 months) - For participants who do not consent to continue in the unblinded Crossover / Booster part of the study, all study procedures will be stopped and participants will be discontinued from the study.
A cluster-randomised controlled Phase IV trial (cRCT) assessing the impact of a Vi-Polysaccharide conjugate vaccine in preventing typhoid infection in Asante Akim, Ghana (TyVEGHA) with a primary endpoint of determining the total protection conferred by single-dose vaccination with Vi-TT against blood culture-confirmed symptomatic S. Typhi infection in the intervention vaccine clusters, compared with the control vaccine clusters.
This project aims to monitor the side effects of COVID-19 vaccines worldwide actively. The primary objectives of the project include a) to estimate the prevalence of each local and systemic side effect of each COVID-19 vaccine among healthcare workers (HCW), old adults over +65 (OA), and schoolteachers (ST); b) to evaluate the potential demographic and medical risk factors for side effects frequency and intensity; c) to evaluate the long-term consequences of COVID-19 vaccines. The secondary objectives include a) to evaluate the relative safety of COVID-19 vaccines compared to each other; b) to evaluate the impact of palliative drugs used by the recently vaccinated individuals on their short-term side effects resolution.
The purpose of this study is to conduct a pragmatic, stepped wedge cluster randomized trial in 12 HIV pediatric clinics in Ghana to determine effectiveness, health benefits, cost and implementation to inform scale-up and sustainability of pediatric disclosure.
DESIGN This pilot study utilizes a mixed-methods approach to develop a novel docu- drama communication strategy, design WhatsApp intervention, evaluate the feasibility of a larger pragmatic randomized controlled trial (RCT) of the two communication strategies and assess acceptability of the communication strategies aimed to increase blood donation among first-time blood donors within the catchment areas of the Southern Zonal Blood Centre (SZBC) in Ghana. In sequence, this pilot study and larger RCT are grounded in the PRECEDE-PROCEED implementation science framework. The pilot study has four components: 1) a qualitative component will be used to design a docu-drama, 2) key informant interviews to guide intervention development, 3) a simultaneous randomized pilot trial will evaluate the feasibility of the larger trial design of communication interventions using WhatsApp compared to control, and 4) a final mixed- methods (quantitative survey and focus groups) assessment of participant views of acceptability, effectiveness, feasibility and cultural appropriateness of the two proposed communication interventions. OBJECTIVES The three objectives of this pilot study are the careful design of a novel docu- drama communication intervention and WhatsApp intervention, evaluation of the feasibility of a larger RCT of communication strategies, and assessment of participant views of the two proposed communication interventions and control among first time blood donors within the catchment areas of the SZBC. For the purposes of registration for clinicaltrials.gov only the randomized pilot trial communication interventions using WhatsApp compared to control is reported. The planned sample size for the pilot RCT is n=128 first-time blood donors. The study population for the pilot RCT is first-time voluntary non-remunerated blood donors (VNRBD) and family/replacement blood donors (FRD) from the SZBC catchment area. REGIMEN WhatsApp: Participants assigned to the WhatsApp group will receive weekly messages developed by communication specialists aimed to motivate blood donation, be encouraged to discuss their blood donation experiences, and share their own motivations for donating blood in a moderated, closed group over a six-month duration. The moderator will provide guidelines on acceptable use of WhatsApp in the group, including images they can or cannot share. Participants will also receive standard NBSG communications for first-time donors. Control: Participants in this group will receive the standard NBSG communications for first-time donors: 1) a thank you phone call and 2) and a reminder phone call two-weeks prior to the second blood donation eligibility. The second blood donation eligibility is four months after the first donation.
