Filter by:The purpose of this study was to determine whether restrictive guidelines for red blood cell (RBC) transfusions for preterm infants can reduce the number of transfusions without adverse consequences.
The purpose of this prospective, randomized study was to determine the efficacy of low bacterial diet, in comparison to normal hospital diet, with gut colonization by aerobic Gram negative rods and yeasts as primary endpoint. In addition, the occurrence of infections and the total costs of hospital care were documented, in order to identify potential cost savings by the use of either diet.
The study is a randomized open label clinical trial to verify the reproducibility of a sporozoite challenge model for Plasmodium vivax in humans. The verification of the reproducibility of such a model will make it possible to evaluate the efficacy of candidate P. vivax vaccines in Phase 2a trials. The study is divided into two successive steps: Step A Parasite Blood Donation: Volunteers will be recruited passively from a group of patients who present with active P. vivax infection and accept to donate infected blood. Samples of P. vivax infected blood will be collected and will be screened for infectious diseases, according to standard blood bank procedures. Colonized Anopheles albimanus mosquitoes will be fed with this blood using a Membrane Feeding Assay (MFA). Sixteen (16) days after, selected positive mosquito batches will be used for step B. Step B Challenge: After informed consent signature, a total of 18 healthy volunteers will be randomly allocated to Groups 1, 2 and 3, of 6 volunteers each and will be challenged with the bite of 3±1, P. vivax infected mosquitoes. Each group will be exposed to a different isolated parasite. Volunteers will be closely monitored post infection, and will be treated as soon as blood infection becomes patent as ascertained by microscopic examination of thick blood smears (TBS). Comparison of data obtained in the three different groups will be used to determine reproducibility of challenge model. Primary objective: To demonstrate that naïve human volunteers can be safely and reproducibly infected by the bite of An. albimanus mosquitoes carrying P. vivax sporozoites in their salivary glands. Secondary objective: To determine the influence of the type of parasite isolated on reproducibility and safety of the challenge model with P. vivax in human volunteers Hypothesis:It is possible to safely develop a reproducible P. vivax infection in human volunteers using P. vivax experimentally infected An. albimanus mosquitoes.
Treatment of anemia associated with chronic kidney disease (CKD) during 36 weeks with safety follow up phase of 52 weeks
This study will determine the appropriate dose and frequency of administration of sc Mircera maintenance therapy in dialysis patients with chronic renal anemia who were previously receiving sc epoetin alfa or beta. The anticipated time on study treatment is 3-12 months and the target sample size is 100-500 individuals.
The purpose of this study is to determine if using Eprex, to maintain hemoglobin within the normal range, will prevent or delay the progression of left ventricular mass growth.
This study will define the effects of ferumoxytol on electrocardiogram (ECG) data as well as evaluate pharmacokinetics
This study will investigate the efficacy, safety and pharmacokinetics of Mircera in adult anemic patients with multiple myeloma. In the first stage of the study, patients will be randomized to receive subcutaneous injections of Mircera once every 3 weeks, at doses of 2.0, 3.5 or 5.0 micrograms/kg. Following the administration of 2 doses, an evaluation of hemoglobin increase will be made at week 6. In the second stage, further groups of patients will receive additional doses of Mircera,at doses of 1.0, 6.5 or 8.0 micrograms/kg, depending on efficacy, safety and pharmacokinetic considerations.The anticipated time on treatment is 3-12 months, and the target sample size is <100 individuals.
To assess the clinical effective dose of KRN321 administered with once triweekly schedule.
The purpose of the study is to determine the efficacy of treatment of anemia with darbepoetin alfa compared to placebo on the composite of time to death from any cause or first hospital admission for worsening heart failure in patients with symptomatic left ventricular systolic dysfunction and anemia.
