There are about 3491 clinical studies being (or have been) conducted in Singapore. 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.
The main purpose of this study is to conduct blood tests to measure how much LY3502970 is in the bloodstream when administered as two different formulations in healthy participants. The study will also evaluate the safety and tolerability of LY3502970. The study will last up to 13 weeks excluding the screening period.
Disease progression is typical for patients with epidermal growth factor receptor mutated (EGFRm) non-small cell lung cancer (NSCLC). Standard platinum-based chemotherapy offers limited efficacy and an unfavorable safety profile.There is an urgent need for more effective and tolerable therapies for patients with EGFRm NSCLC who have exhausted available targeted therapies. Clinical evidence suggest that patritumab deruxtecan constitutes a promising investigational therapy for patients with EGFRm NSCLC.
The purpose of this study is to evaluate the safety and effectiveness of triplet therapy of nivolumab, relatlimab and bevacizumab versus nivolumab and bevacizumab in participants with untreated advanced/metastatic hepatocellular carcinoma (HCC).
South Asian men have lower cardiorespiratory fitness (CRF) than white men which is associated with a reduced capacity to oxidise fat during exercise. This is a risk factor for weight gain/regain. Whilst comparisons with Europeans are valuable, Asians are not a homogenous group and substantial differences in obesity and body fat partitioning exist with ethnicity. This cross-sectional pilot investigation aims to compare CRF and fat oxidation at rest and during exercise in Chinese, Indian and Malay men (from Singapore) with elevated BMI (23 -30 kg/m2). Forty-five men (15 each ethnicity) with elevated body mass index (23 -30 kg/m2) will complete testing in a fasted state on two separate mornings separated by ≥72 hours: (i) for a measure of CRF; and (ii) for a measure of fat oxidation at rest and during incremental exercise.
This is a global, prospective, multi-center study that is designed to assess the long-term safety and efficacy of OAV101 in patients who participated in an OAV101 clinical trial. The assessments of safety and efficacy in Study COAV101A12308 will continue for 15 years from the date of OAV101 administration in the previous clinical trial.
Drug-coated balloon (DCB) angioplasty has been shown to be superior to POBA in the treatment of stenosis in AVF. This is because the very intervention used to treat underlying stenosis by POBA can induce vascular injury and accelerate intimal hyperplasia, resulting in rapid restenosis and need for repeated procedure to maintain vessel patency. The anti-proliferative drug that is coated on the surface of balloon is released to the vessel wall during balloon angioplasty and blunt the acceleration of intimal hyperplasia response, resulting in improved primary patency after angioplasty. Additionally, unlike stents, DCB does not leave a permanent structure that may impede future surgical revision. Recent randomized control trials (RCT) have shown the superiority of paclitaxel durg-coated balloon (PDCB) over POBA in the treatment of stenosis in AVFs. In a large multicenter RCT, PDCB was demonstrated to result in a 6-month target lesion primary patency of 82.2% compared to 59.5% for POBA. However, concerns had also arisen recently in the use of PDCB. In large lower limb studies involving the use of paclitaxel devices, meta-analysis by Katsanos et al had revealed increased late risk mortality in patient that are treated with PDCB or paclitaxel-coated stent. Sirolimus drug-coated balloon (SDCB) is the new generation of drug eluting balloons that are available in the market. Compared to paclitaxel, sirolimus is cytostatic in its mode of action with a high margin of safety. It has a high transfer rate to the vessel wall and effectively inhibit neointimal hyperplasia in the porcine coronary model. The effectiveness of SDCB in patients with dialysis access dysfunction has been shown in a small pilot study in AVF stenosis and AVG thrombosis. SAVE AVF registry ams to assess the efficacy and safety of SDCB vs PDCB angioplasty.
This main aim of the study is to investigate the changes in neurophysiological features after stroke, and its association with upper limb motor recovery, so as to establish a prognostic model for upper limb motor recovery after stroke. The investigators hypothesize that a combination of neurophysiological features measured by transcranial magnetic stimulation (TMS), high density electroencephalography (HD-EEG), functional magnetic resonance imaging (fMRI) and Diffusion Tensor Imaging (DTI) might be used as biomarkers to predict upper limb motor outcomes after stroke. The investigators also hypothesize that non-invasive brain stimulation strategies such as tDCS will more effectively improve motor outcomes as an adjunct to therapy, if tailored according to patient's predicted pattern of neural reorganization.
This is a monocenter, randomized, controlled, parallel-group, double-masked clinical trial to evaluate the effectiveness of test lens in slowing myopia progression with respect to axial length elongation at baseline compared to a single vision spectacle lens (control). A total of 80 children will be recruited where 40 subjects will be allocated either to wear test lenses (group 1) or control lenses (group 2) for 1 year through randomization.
Background: Laparoscopic sleeve gastrectomy (LSG) is one of the commonest bariatric procedures. However, it is associated with postoperative gastroesophageal reflux disease (GERD) and erosive esophagitis (EE). The investigators' preliminary study suggests that the incidence of postoperative GERD and EE appears to be correlated with the preoperative presence of a lax gastroesophageal flap valve and hiatal hernia. Hypothesis/ Aim: To investigate the impact of a concomitant hiatal hernia repair with LSG on the incidence of postoperative EE. Significance: For patients with pre-existing EE, most surgeons will recommend a laparoscopic Roux-en-Y gastric bypass (LRYGB) as their primary bariatric procedure. However, compared to LSG, LRYGB is a technically more demanding procedure with increased morbidity and long term nutritional deficiencies. For asymptomatic patients at risk of postoperative EE due to presence of a hiatal hernia, there is still no consensus on the most appropriate bariatric surgical option. A LSG with a concomitant hiatal hernia repair, if shown to reduce EE postoperatively, may help to expand the pool of patients suitable for LSG in the future. Methods: A two center, double-blinded, randomized controlled trial of all patients, undergoing LSG with a preoperative diagnosis of a Hill's grade III gastroesophageal junction, will be randomized to having a concomitant hiatal hernia repair (experimental arm) versus just LSG alone (control arm). Primary outcome measures include 1-year postoperative EE on endoscopy. Secondary outcome measures include postoperative morbidity, blood loss, quality of life and GERD symptoms at 1-year postoperatively.
COVID-19 vaccine response data in children 5 to 11 years old remain scarce. Our understanding of the safety and immune responses including humoral and cellular responses generated in children remains limited. Safety of the vaccine is critical in the risk benefit assessment of vaccination in young children. Available data show a trend for increased risk of myocarditis after second dose, especially in males and younger age groups. It is unknown if reduced antigen dose will alter this risk in 5y to <12y age group. Reassuringly, data from early roll-out in the USA have not reported any safety signals to date. Alternate (reduce dosing or delayed dosing) strategies could help ensure maximum protection with reduced risk of side-effects. There is currently no data available to inform how long protection would last in the reduced dose or delayed dosing strategy. The trial will inform the potential use of alternate dosing schedules such as single dose or delayed dose to minimise risk and maximise benefit of COVID-19 vaccination in children 5 to 11 years old.
