There are about 141 clinical studies being (or have been) conducted in Cameroon. 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 study aims to assess the long-term outcomes of children infected with HIV, having participated in the ANRS 12140 PediacamI study, in terms of: clinical and immunovirological response to ARV therapy, long-term ARV tolerance, and the impact of family environment and lifestyle on adherence to ARV treatment.
Background The burden of sudden death (SD) in sub-Saharan Africa is unknown. The aim is to assess the incidence, etiology and patient characteristics of SD in a sub-Saharan country. Methods The Douala-SD study is a prospective, multicenter, community-based registry monitoring all cases of SD occurring in index areas of Douala city. Investigators will use the definition of SD as natural death occurring within 24h at the onset of symptoms. Demographic, clinical, electrocardiographic and biological variables (when available) of victims will be recorded. All deaths occurring in residents of health areas of interest will be checked for past medical history, circumstances of death, and autopsy (if possible). Conclusion This maiden Douala-SD study will provide comprehensive, contemporary data on the epidemiology of SD in a sub-Saharan African country and will help in the development of strategies to prevent and manage SD in Africa.
Significant progress has been made in the treatment of Wilms tumor in high income countries, where survival is now around 85% - 90%. Survival in low income countries is much lower; specific challenges include late presentation, malnutrition, less intense supportive care facilities and failure to complete treatment. A comprehensive treatment guideline was introduced in Malawi in 2006 which included nutritional support and social support to enable parents to complete treatment. Survival has increased to around 50%; 95% of children completed their treatment. A multi-disciplinary group of African clinicians and 'state of the art' experts produced a consensus treatment guideline for children with Wilms tumor in sub-Saharan Africa. This guideline will be implemented as a multi-center prospective clinical trial in 2014 in six - eight institutes, expecting about 200 new patients per year. The hypothesis is that 2 year event free survival will be 50%, with <10% failure to complete treatment and <10% treatment related mortality. Other research questions include efficacy and toxicity of preoperative chemotherapy and the comparison of surgical staging, local pathology and central review pathology in stratifying postoperative chemotherapy.
Multicenter, randomized, superiority trial to evaluate efficacy of a mono or bi-therapy of protease inhibitors with or without lamivudine over a period of 96 weeks. The primary outcome will be the failure rate at 96 weeks. This study will include 260 participants, former participants of the 2LADY trial. It will be carried out in Yaoundé, Bobo Dioulasso and Dakar.
The purpose of this study is to determine whether an improved corn-soya blend (CSB+) and a new formulated ready-to-use supplementary food (RUSF) are effective in the treatment of moderate acute malnutrition in children.
To assess the efficacy of artesunate-amodiaquine, dihydroartemisinin-piperaquine, in comparison with artemether-lumefantrine during 42 days follow up period in 720 children with acute uncomplicated P. falciparum malaria, in two different endemic ecological areas - Savanna and equatorial forest regions of Cameroon. We have set as specific objectives: - To assess the efficacy of artesunate-amodiaquine, dihydroartemisinin-piperaquine, in comparison with artemether-lumefantrine during 14 and 28 days follow up period in children with acute uncomplicated P. falciparum malaria in two different endemic areas. - To evaluate the safety of artesunate-amodiaquine, dihydroartemisinin-piperaquine, in comparison with artemether-lumefantrine during 42 days follow up period in children with acute uncomplicated P. falciparum malaria. - To determine parasite clearance time (PCT) and fever clearance time (FCT) following the administration of the three trial regimens. - To investigate the treatment response based on WHO criteria (WHO, 2003) in patients in all groups after trial. - To investigate the Single Nucleotide Polymorphisms (SNPs) and microsatellite markers of genes associated with drug resistance
The purpose of this study is to demonstrate noninferiority (a new treatment is equivalent to standard treatment) in terms of the percentage of patients who have plasma human immunodeficiency virus-type 1 (HIV-1) ribonucleic acid (RNA) levels less than 400 copies per mL after 48 weeks of randomized treatment with tenofovir disoproxil fumarate/emtricitabine/rilpivirine (TDF/FTC/RPV) versus TDF/FTC/efavirenz (TDF/FTC/EFV).
Background: - Loa loa is a small worm that infects people in West and Central Africa. It is spread by the bite of a fly. Adult worms live under the skin and can cause swelling in the arms, legs, and face. Some people have more serious infections in the heart, kidneys, or brain. Most people with Loa loa infection have no symptoms at all. The standard treatment for Loa loa infection is a medicine called diethylcarbamazine (DEC). Some people have bad reactions to DEC, including itching, muscle pains, and in severe cases coma and death. - Another drug, ivermectin, is used in mass drug treatment programs to prevent the spread of worm infections that cause blindness and massive swelling (elephantiasis). However, people who also have Loa loa have had serious bad reactions to ivermectin. Researchers want to study both DEC and ivermectin to find out why these reactions occur. If they can be prevented, mass drug treatment programs will be able to be used in areas in Africa where Loa loa exists. Objectives: - To study the side effects of DEC and ivermectin treatment for Loa loa infection. Eligibility: - Individuals who live in 4 villages in Cameroon where Loa loa infection is known to exist, who are between 20 and 60 years of age, not pregnant or breastfeeding and have a low level of Loa loa parasites in the blood, but are otherwise healthy. Design: - Participants will be screened with a physical exam and medical history. Blood samples will be collected to check for Loa loa infection. Participants will also have an eye exam and provide skin samples to check for other worm infections that may interfere with the study treatment. - Participants will be admitted to the hospital for 4 days (during and after the treatment). They will receive a single dose of either DEC or ivermectin. - After treatment, regular blood samples will be collected. Participants will be asked questions about how they feel after treatment. Physical exams will be performed. If side effects develop, participants will be treated at the hospital. - After leaving the hospital, participants will have followup visits. These visits will happen on days 5, 7, 9, and 14 after receiving the study medicine. They will involve a short physical exam and collection of blood samples. - At the end of the study, participants will be offered a full 21-day DEC treatment to cure the Loa loa infection.
The primary objective of the study is to compare the tolerance and safety between a low-dose Zidovudine (AZT) containing regimen (200 mg BID) and a standard dosage (300 mg BID) in HIV patients initiating a first line antiretroviral therapy. The investigators expect that the low-dose regimen will show improved tolerability and safety compared to the standard dosage, with significant reduction in number of patients experiencing a new grade 1 to 4 anaemia or increasing their anaemia grade during the first 6 months of treatment. The secondary objectives of the study is to compare the efficacy of the two dosing regimen, as measured by classical clinical and biological markers: the number of new AIDS defining illness, the mortality rate, the proportion of patients achieving virological success and the mean CD4 cell count increase from baseline.
ANRS 12127 Prenahtest is an intervention trial conducted in four countries (Cameroon, Dominican Republic, Georgia and India), where pregnant women are randomized during prenatal care to receive either standard post-test HIV counseling, or an innovative intervention called couple-oriented post-test HIV counseling (COC). The aim of the COC intervention is to empower women to communicate with her male partner about HIV, and HIV testing in particular, and encourage him to return for HIV testing and/or couple HIV counseling (where both couple members are counseled together). Prenahtest is the first randomised trial testing a prenatal intervention to increase partner HIV testing.
