There are about 1320 clinical studies being (or have been) conducted in Saudi Arabia. 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.
In the First-line Antimetabolites as Steroid-sparing Treatment (FAST) Uveitis Trial, the investigators propose to establish which immunosuppressive therapy, methotrexate or mycophenolate mofetil, is more effective as a first-line, corticosteroid-sparing agent for the treatment of non-infectious uveitis in a block-randomized, observer-masked, comparative effectiveness trial.
Clopidogrel is crucial as antiplatelet treatment in patients undergoing percutaneous coronary intervention (PCI) with stent implantation and during one year after PCI, to prevent atherothrombotic complications. However, clopidogrel is ineffective in certain patients due to genetic mutation in CYP2C19 gene a specific enzyme in the liver required for metabolism of clopidogrel. Therefore, the purpose of this study is to test these patients genetically at bedside and prescribe an alternative drug such as Ticagrelor (90 mg twice daily) or prasugrel ( 10mg once daily or 5mg once daily if the patient older than 75 years or a body weight < 60kg) if they are carriers of the allele 2 or 3 of the mutated gene.
This international study is a prospective noninterventional observational cohort study of patients with non-valvular atrial fibrillation who are prescribed rivaroxaban under routine treatment conditions to prevent stroke or non-central nervous system systemic embolism. Patients will be followed up for 1 year or until 30 days after end of rivaroxaban therapy in case of therapy was discontinued earlier than 12 months. Serious adverse events will be followed up adequately. Laboratory values (e.g., Hb, HCT, haemoccult) should be documented for each point in time they were measured.
To evaluate the efficacy of prophylactic glycerin suppositories will accelerate the elimination of meconium from the large intestine and thus reduce the incidence of feeding intolerance in very low birth weight (VLBW) infants
The main purpose of the study is to evaluate the efficacy and safety of the study drug known as prasugrel for the reduction of Vaso-Occlusive Crisis events in pediatric participants with sickle cell disease. The study will also investigate reduction in daily pain in children who have sickle cell disease.
TARGIT-Boost is an international randomised clinical trial designed to test the hypothesis that the tumour bed boost delivered as a single dose of targeted intraoperative radiotherapy (TARGIT-B) is superior to the conventional course of external beam radiotherapy boost (EBRT-Boost), especially in women with high risk of local recurrence. It is a pragmatic trial in which each participating centre can use the local predefined inclusion/exclusion criteria for entry into the trial. Only centres with access to the Intrabeam® (Carl Zeiss) are eligible to enter patients into the trial. Eligible patients are those with a higher risk of local recurrence after breast conserving surgery. After giving consent patients are randomised to either TARGIT Boost or EBRT Boost. All patients will receive whole breast EBRT. They may receive any other adjuvant treatments as deemed necessary. The protocol recommends that patients be followed at six monthly intervals for three years and then annually. The primary endpoint is ipsilateral breast recurrence rate. Secondary endpoints are relapse-free survival, site of recurrence, overall survival (breast-cancer specific and non-breast cancer deaths) patient satisfaction and quality of life.
Probiotics, which are believed to be health promoting live microorganisms, have been reported to influence circulating endotoxin levels. Ingestion of the live cultures may alter gut mircobiota in a beneficial manner to reduce inflammation; although their mechanism and influence to reduce inflammation in T2DM is not established for this disease state. Therefore, the aim of this study is to (1) characterize the beneficial effects of probiotics on circulating endotoxin levels and other biomarkers related to systemic low-grade inflammation in patients with T2DM; (2) Compare circulating endotoxin levels and inflammatory cytokine levels between patients treated with probiotics or placebo to examine the beneficial effects of probiotics on reducing the inflammatory status, through assessment of systemic markers (adipokines, endotoxin, cytokines); (3) to examine the effects of probiotics on gut microflora in order to understand the mechanism for such change in inflammatory status. To achieve this, 120 consenting adult Saudis, naïve or newly diagnosed T2DM patients without co-morbidities, will be enrolled in this clinical trial and randomized to receive twice-daily placebo or probiotics for 26 weeks in a double-blind manner. Glycemic inflammatory markers will be measured and fecal samples analysed, interventions will be done at baseline, 4, 8, 12 and 26 weeks. It is envisaged that probiotics will induce beneficial changes in gut mircobiota, reduce the systemic inflammatory state through altering systemic endotoxin levels and, as such, reduce the systemic inflammatory response observed in T2DM subjects. This will have a fundamental impact on how we should treat the inflammatory component of T2DM, particularly once the results are verified in a larger cohort of patients, as this could have very dramatic effects on how we treat patients with T2DM. Reducing the pathogenesis of T2DM by dampening the inflammatory response, which may also impact on insulin resistance status and health of the individual, will have clear benefits. This could have profound effects on preventative T2DM management, as well as current T2DM care without excessive cost for the wider Saudi health economy.
The use of pressure controlled ventilation (TV) during one lung ventilation (OLV) for thoracic surgery is associated with comparable oxygenation with volume controlled ventilation (VCV) with added benefits of decreasing airway pressures and shunt fraction. The later may improve the right ventricular (RV) function during OLV. We postulate that the use of PCV during OLV for thoracic surgery would preserve RV function than during VCV. After local ethics committee approval and informed consent, we will randomly allocate 28 patients scheduled for elective thoracic surgery OLV to randomly crossed from PCV to VCV mode (n= 14 for each) during with VT of 6 mL/kg, I: E ratio 1: 2.5, PEEP of 5 cm H2O, recruitment maneuvers and respiratory rate will be adjusted to maintain normocapnia. Intraoperative changes in the right ventricular function (peak systolic and diastolic tricuspid annular velocity (TAV), end-diastolic volume (EDV), end-systolic volume (ESV), and RV fractional area changes (RV-FAC)), hemodynamic and oxygenation parameters, peak and plateau airway pressures, compliance will be recorded.
The use of low tidal volume (TV) during one lung ventilation (OLV) for thoracic surgery decreases the incidence of postoperative acute lung injury (ALI). We postulated that the use of low TV during OLV for video-assisted thoracoscopic surgery (VATS) would decrease the extravascular lung water content index (EVLWI). After local ethics committee approval and informed consent, we will randomly allocate 60 patients scheduled for elective VATS to ventilate the dependent lung with VT of 4, 6, or 8 mL/kg (n= 20 for each), I: E ratio 1: 2.5, PEEP of 5 cm H2O, recruitment maneuvers and respiratory rate will be adjusted to maintain normocapnia. Perioperative changes in EVLWI, hemodynamics, oxygenation index will be recorded. Also, the incidence of postoperative ALI, morbidity, hospitalization and mortality will be recorded
