There are about 1159 clinical studies being (or have been) conducted in Indonesia. 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.
Studies showed that in cases of gastrointestinal bleeding, injection tranexamic acid decreasing the risk of death and the need of surgical intervention. However, the quality of most clinical trials were not good and the results were not significant. Injection tranexamic acid does not become one of the treatment option in the international guidelines nor in national consensus, so the effectiveness and the safety of its use in the treatment of gastrointestinal bleeding remains unclear and not routinely used. In Indonesia, injection tranexamic acid in gastrointestinal bleeding is limitedly used and recorded. Therefore, a clinical trial study of injection tranexamic acid is required to assess the effectiveness and the safety in the treatment of gastrointestinal bleeding.
Background: Mortality from severe malaria remains ~15% despite the use of the most rapidly parasiticidal antimalarial therapy, artesunate. Adjunctive treatments may improve outcome. Our overall goal is to determine if adjunctive treatment with L-arginine is safe and improves outcomes in severe malaria. In studies to date, we have shown that L-arginine is safe in moderately severe malaria, increases nitric oxide production and improves endothelial function. We now propose to extend these studies to patients with severe malaria. Aims: To determine the safety, preliminary efficacy, pharmacokinetics and pharmacodynamics of L-arginine infusion in severe malaria. Hypothesis: L-arginine will improve endothelial function, lactate clearance time and tissue oxygen delivery compared to saline with no clinically significant adverse effects. Methods: Based on previous pharmacokinetic modeling and simulations, we propose a phase 2A randomised controlled trial of L-arginine vs saline in severe malaria, each given over 8 hours. If safety is demonstrated this will be followed by a phase 2B open-label study of 24-hour infusion of L-arginine in severe malaria with safety and preliminary efficacy compared with the 8 hour infusions given in phase 2A. The primary outcomes will be the improvement in endothelial function and lactate clearance in patients given L-arginine infusion compared with those who received saline. Among the secondary outcomes will be safety and the effect of L-arginine vs saline on tissue oxygen delivery (NIRS). Data from both phase 2A and 2B will be used to generate a pharmacokinetic/ pharmacodynamic model.
