NCT ID: NCT01059240 Completed - Clinical trials for Spinal Muscular Atrophy

SMN Copy Number Distribution in Mali, West Africa

Start date: January 21, 2010
Phase:
Study type: Observational

Background: - Spinal muscular atrophy (SMA) is a degenerative and incurable neuromuscular disorder that is caused by mutations in the survival motor neuron gene, SMN1, found on chromosome 5. It is the leading inherited cause of infant mortality. SMA carriers (those who have the genetic mutation but do not have the disease) are often unaware of their status until they are tested. - Researchers have been studying the prevalence of SMA carriers in the general population, but most of the information collected has come from populations within the United States, Europe, and Asia. Very few studies have been performed in Africa. Furthermore, this information does not provide much information regarding carrier frequency based on ethnic background and ancestry. To address this problem, researchers are interested in studying the prevalence of the SMA genetic mutation in the sub-Saharan nation of Mali. Objectives: - To collect blood samples for use in studying genetic data related to spinal muscular atrophy. Eligibility: - Healthy volunteers who are at least 18 years of age. - Volunteers will be of Malian ancestry and nationality. Study Location: -<TAB>Bamako, Mali, West Africa Design: - The study will first collect blood samples from a small group of volunteers to run initial SMA carrier testing and resolve any technical difficulties before continuing with the study. - Participants will complete questionnaires about their personal and family medical history, including questions about illnesses, stillborns, and miscarriages, and then will provide blood samples for genetic research and testing.

NCT ID: NCT01015950 Completed - Clinical trials for Moderate Acute Malnutrition (MAM)

Management of Children With Moderate Acute Malnutrition in Mali

Mali-MMAM
Start date: May 2010
Phase: N/A
Study type: Interventional

The objectives of the study are to assess the impact of different dietary strategies for the management of children with MAM on: the children's continued participation in the nutritional rehabilitation program and their physical growth, recovery from MAM, and change in micronutrient status and body composition. The specific dietary regimens that will be compared are: 1) a ready-to-use, lipid-based supplementary food (Plumpy'Sup, Nutriset, Inc.), providing ~500 kcal/d for 12 weeks; 2) specially formulated CSB for malnourished children, providing ~ 500 kcal/d for 12 weeks; 3) Misola, a locally produced, micronutrient-fortified, cereal-legume blend, providing ~500 kcal/d for 12 weeks; or 4) packaged, home available foods (millet and cowpea flour, sugar, vegetable oil) and a multiple micronutrient powder ("Mix Me") for 12 weeks, as is currently recommended by the national CMAM protocol when special foods are not available.

NCT ID: NCT00889616 Completed - Malaria Clinical Trials

Phase I Study of the Safety and Immunogenicity of BSAM-2/Alhydrogel +CPG 7909, an Asexual Blood Stage Vaccine for Plasmodium Falciparum Malaria in Adults in the US and Mali

Start date: April 23, 2009
Phase: Phase 1
Study type: Interventional

Background: - Globally, the Plasmodium falciparum parasite is responsible for at least 247 million acute cases of malaria each year, resulting in about 1 million deaths. Approximately 90 percent of these deaths, the majority in children under 5 years of age, occur in Africa due to infection with P. falciparum. - People living in endemic areas develop natural immunity to P. falciparum as a result of repeated infection. Consequently, children who survive to 5 years of age rarely succumb to life-threatening disease despite frequent infection. This acquired immunity is mediated in part by blood-stage parasite-specific antibodies. Thus, parasite proteins expressed during the blood-stage have been proposed as good candidates for inclusion in a vaccine. - A number of P. falciparum merozoite antigens have been identified as promising blood-stage vaccine candidates, including Merozoite Surface Protein 1 (MSP 1) and Apical Membrane Antigen 1 (AMA 1). This Phase I study is the first time that the combination vaccine (BSAM-2/Alhydrogel +CPG 7909) will be given to humans. The vaccine will be administered in a randomized, open-label (U.S.)/single-blinded (Mali), dose-escalating trial. Objectives: - To assess safety and reactogenicity of the combination vaccine (BSAM-2/Alhydrogel +CPG 7909) in malaria-naive U.S. adults and semi-immune Malian adults. - To determine the antibody response of the combination vaccine to the AMA 1 and MSP 142 proteins, as measured by antibody levels and parasite growth inhibition. - To determine the extent to which the antibody response to the individual antigens (AMA 1 and MSP 142) is correlated when the combination vaccine is given, and to determine T and B cell responses to vaccination. Eligibility: - United States: Healthy volunteers between 18 and 50 years, inclusive. Available for the 52 weeks of the trial and willing to participate in the study as evidenced by signing the informed consent document. - Mali: Healthy volunteers between 18 and 45 years, inclusive, and a known resident of the village of Bancoumana. Available for the 52 weeks of the trial; willing to participate in the study as evidenced by signing the informed consent document or by fingerprinting the consent document with the signature of a witness. - Potential participants must meet extensive health and screening requirements to participate in this study. Good general health is required as a result of review of medical history and clinical testing at the time of screening. - Women who are pregnant or breastfeeding are not eligible. Design: - During the 52-week study, participants will receive the first vaccine and complete the following: - Physical examination and patient education regarding the signs and symptoms of potential adverse effects. - Blood and urine testing, and vital signs (blood pressure, temperature, heart rate, and respiratory rate). - United States: Education on the use of digital thermometer, injection-site reaction measurement, and malaria vaccine side-effect memory enhancement tool (daily symptom diaries). - Mali: Additional blood draws for malaria smear and urine test for chloroquine testing. - U.S. and Mali participants will return to the study site on specified days throughout the 52 weeks to receive two additional vaccines, record vital signs, complete additional blood and urine testing, and review patient education. - U.S. participants will record oral temperature once during the day, as well as pain, tenderness, redness, swelling at the injection site and any systemic signs or symptoms for 6 days following each immunization. - Participants will receive financial compensation (United States) or food (Mali) to compensate for their time.

NCT ID: NCT00867048 Completed - HIV Infection Clinical Trials

Strategic Timing of Antiretroviral Treatment

START
Start date: April 15, 2009
Phase: Phase 4
Study type: Interventional

Objectives: - To find out if the chance of developing a serious illness or of getting AIDS is less if patients start taking HIV medicines at a time when their cluster-of-differentiation-4 (CD4)+ cell count is still fairly high, instead of waiting until the CD4+ count is at the level where there is good evidence for starting medicines. - To learn more about how a strategy of starting HIV medicines early might affect other aspects of care, such as the chances of developing other illnesses or resistance to HIV medicines, the frequency of doctor visits, the cost of medical care, and general health and satisfaction.

NCT ID: NCT00772642 Completed - Malaria Clinical Trials

Immune Parameters in the Cord Blood of Newborns Exposed to Malaria in the Womb

Start date: October 8, 2008
Phase: N/A
Study type: Observational

This study, conducted by the Malaria Research and Training Center at the University of Bamako, Mali, and the NIAID, will examine how exposure to the malaria parasite in the womb affects the developing immune system of newborns. Little is known about how such exposure in the womb may affect the immune system or alter the risk of malaria or responsiveness to vaccination after birth. A better understanding of this process may provide information useful for childhood vaccination strategies in areas where malaria is widespread. Women 18 years of age and older who live in Bancoumana and are in their last trimester of pregnancy and in good health may be eligible for this study. Participants have blood samples drawn from a finger stick and through a needle placed in a vein two times for this study: when they enroll in the study and again when they go to the Bancoumana Health Center to deliver their baby. After the baby and placenta are delivered, blood is collected from the umbilical cord and placenta.

NCT ID: NCT00766662 Completed - Malaria Clinical Trials

Intermittent Preventive Treatment in Infant in Mali

Start date: October 2006
Phase: N/A
Study type: Interventional

Studies have shown that Intermittent preventive treatment in infants (IPTi) with Sulfadoxine-pyrimethamine (SP)reduced the incidence of clinical malaria and anemia without modifying infants' serological response to EPI vaccines. Thus IPTi was seen as a potential public health tool of great benefit to the children of Africa and a logical addition to the Immunization Plus package. The objectives of this operational researcher were - to develop an implementation model for IPTi in the health care system in Mali - to assess its impact on the EPI vaccines and other health interventions coverage - and on molecular makers of resistance to SP

NCT ID: NCT00740090 Completed - Malaria Clinical Trials

Malaria Vaccine for Children in Mali

Start date: August 11, 2008
Phase: Phase 1
Study type: Interventional

This study will evaluate the safety and immune response of children to an experimental malaria vaccine called AMA1-C1/Alhydrogel® (Registered Trademark) + CPG 7909. Malaria is an infection of red blood cells caused by a parasite, Plasmodium falciparum, that is spread by certain kinds of mosquitoes. It affects at least 300 million people worldwide each year, with more than 1 million deaths, mostly among children less than 5 years of age in sub-Saharan Africa. Malaria is the leading cause of death and illness among the general population of Mali in West Africa. Increasing drug resistance to P. falciparum and widespread resistance of mosquitoes to pesticides are reducing the ability to control the disease through these strategies. AMA1 C1 is made from a synthetic protein similar to a P. falciparum protein. It is combined with Alhydrogel and CPG 7909, substances added to vaccines to make them work better. Children between 1 and 4 years of age who live in Bancoumana, Mali, and are in general good health may be eligible for this study. Candidates are screened with a medical history, physical examination, and blood and urine tests. Participants are randomly assigned to receive three injections (shots) of either AMA1-C1 or a control rabies inactivated vaccine called Imovax® (Registered Trademark). The shots are given in the thigh muscle on study days 0, 56 and 180. After each shot, participants are observed in the clinic for 30 minutes. They return to the clinic for a physical examination six or seven times between each shot and then four more times over a 9-month period after the last shot. Blood samples are drawn at several of these visits to check for side effects of the vaccine and to measure the response to it. The total duration of the study is 21 months.

NCT ID: NCT00738946 Completed - Malaria Clinical Trials

A Trial of the Combined Impact of Intermittent Preventive Treatment and Insecticide Treated Bednets in Reducing Morbidity From Malaria in African Children

IPTc/ITNs
Start date: August 2008
Phase: N/A
Study type: Interventional

An investigation will be made of the combined impact of insecticide-treated nets and intermittent preventive treatment with amodiaquine + sulfadoxine-pyrimethamine on malaria morbidity in children in Burkina Faso and Mali.Three rounds of treatment will be given during the malaria season in one year and the follow-up will be extended into the second year by passive surveillance.

NCT ID: NCT00703404 Completed - HIV Infections Clinical Trials

Response to Standard HIV Treatment in Bamako, Mali

Start date: June 18, 2008
Phase:
Study type: Observational

This study will evaluate the effectiveness of first-line HIV treatment (fixed-dose combination of the generic antiretroviral drugs nevirapine, stavudine and lamivudine) provided by the Malian National HIV Treatment Program. Antiretroviral therapy has become a priority because of its proven effectiveness in decreasing sickness and death from HIV infection. Reliable information on its efficacy is needed. Patients 18 years of age and older who enter the Malian National HIV Treatment Program and have not had prior antiretroviral treatment may be eligible for this study. Primary Objective The primary objective is to measure the virologic treatment response at 24 weeks to the Malian-approved fixed-dose regimen (FDC) of nevirapine, stavudine and lamivudine (Triomune) in patients who are na(SqrRoot) ve to antiretroviral therapy in Bamako, Mali compared to a historical cohort as a prelude to further clinical research investigations in Mali. Secondary Objectives 1. To assess the association of the 24 week response with the response at one year as measured by suppression of viremia to less than 50 copies/mL 2. To evaluate the baseline clinical and HIV-associated characteristics of a cohort of persons who are enrolled in protocol-mandated monitoring. Participants undergo treatment in the government-sponsored program. Clinical visits are scheduled at study days 0 (antiviral therapy start day) and 14, and at 1, 3, 6, 9 and 12 months. Patients undergo a medical history, including all confirmed and probably diagnoses made since the previous visit and current status, physical examination and blood tests for CD4 and viral load at each visit. Study start date: July 2008
