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.
Chronic Hepatitis B carriers (normal LFTs and viral load < 2 x 10^4 IU/ml are not recommended to be treated by guidelines as they are at low risk for complications. However, it is unclear if treatment can enhance HBsAg loss which has been shown to be associated with significantly lower risk of complications compared to those without HBsAg loss. Consequently, this is a proof of concept study to determine the possibility of HBsAg loss in Chronic Hepatitis B carriers in a randomised open label clinical trial comparing no treatment to 24 weeks peg-interferon alpha 2a or 48 weeks peginterferon alpha 2a (randomised 1:1:1). The primary endpoint of HBsAg loss will be evaluated 24 weeks after the end of therapy for those on therapy and matched to an equivalent timepoint in the control arm. The sample size calculation is 30 patients in each arm for a 20% difference between any experimental arm and the control arm.
The study intends to evaluate the following objectives in patients with advanced or metastatic biliary tract cancer who have not received systemic therapy for advanced/metastatic disease. Primary Objectives: Phase 1B - To determine the maximum tolerated dose (MTD), as determined by dose-limiting toxicities (DLTs), and to characterise the safety profile of Varlitinib in combination with Gemcitabine and Cisplatin. Phase 2A - To further evaluate the safety and tolerability of Varlitinib in combination with Gemcitabine and Cisplatin at the recommended phase 2 dose (RP2D). - To provide a preliminary assessment of the clinical activity of Varlitinib in combination with Gemcitabine and Cisplatin at the RP2D as measured by Objective Response Rate (ORR) and progression-free survival (PFS) (based on RECIST v1.1) Phase 2B - To compare the efficacy of Varlitinib in combination with Gemcitabine and Cisplatin to placebo in combination with Gemcitabine and Cisplatin as measured by progression-free survival (based on RECIST v1.1).
This open-label, prospective, multi-center, non-interventional, observational, parallel cohort study intended to provide real life data on the treatment duration, effectiveness and safety of tedizolid and linezolid when treating ABSSSI hospitalized patients in a real practice setting.
This phase II trial studies how well ibrutinib works in treating patients with follicular lymphoma that has come back after a period of improvement or does not respond to treatment. Ibrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
To test the hypothesis that a regimen of 200 mg oral mifepristone, with the option of home administration, followed by 800 μg buccal misoprostol 24 hours later for abortion through 70 days LMP will be feasible and acceptable in Singapore.
The purpose of this study is to investigate the intraocular pressure-lowering effect and the safety of DE-117 ophthalmic solution compared with Latanoprost ophthalmic solution in subjects with open angle glaucoma or ocular hypertension.
Meal size is strongly influenced by a number of external features of the food environment which can promote over-consumption, such as the availability of palatable energy dense foods and large portion sizes. The current research aimed to investigate whether natural food-based differences in texture could be used to slow down eating rate and reduce intake from large portions. A four-session randomised crossover study assessed the effect of faster vs. slower eating rate, achieved through manipulating food texture, on ad-libitum consumption (weight and calories) of a meal, alone and in combination with variations in meal portion size (regular vs. large)
Meal size is strongly influenced by a number of external features of the food environment which can promote over-consumption, such as the availability of palatable energy dense foods. The current research aimed to investigate whether natural food-based differences in texture could be used to slow down eating rate and reduce intake from large portions and higher energy dense foods. A four-session randomised crossover study assessed the effect of faster vs. slower eating rate, achieved through manipulating food texture, on ad-libitum consumption (weight and calories) at a meal, alone and in combination with variations in meal energy-density (higher vs. lower)
Imaging using 11C-acetate PET (positron emission tomography) in patients with tuberculosis (TB) may be able to detect non-replicating persister bacilli. This may permit identification of those patients at risk of relapse following completion of TB treatment. The main aim of this pilot study is to assess the ability of 11C-acetate PET to detect pulmonary lesions in individuals with active pulmonary TB.
Background: Hypertension is a serious public health problem responsible for significant mortality and morbidity from cardiovascular disease. In Singapore, 1 in 4 adults age 30 years or older suffer from hypertension. Nearly half of these patients have uncontrolled hypertension and only 50% of individuals are on antihypertensive treatment. Our study aims to evaluate the effectiveness, cost effectiveness and impact on medication adherence of a well-structured program using multicomponent intervention for hypertension control aimed at overall cardiovascular risk reduction among individuals with hypertension attending the polyclinics in Singapore, compared to existing services. Such a program is expected to be cost-effective in terms of improving hypertensive individuals' outcomes, and to be potentially scalable and sustainable. Methods/design: Cluster randomized trial of 8 of the nine SingHealth Polyclinics randomized to intervention or usual care (4 each) and followed up for 2 years post randomization Intervention: The structured multicomponent primary care program comprises of: 1) algorithm-driven antihypertensive treatment for all hypertensive individuals and using fixed-dose combination (FDC) and lipid-lowering medication for high-risk hypertensive individuals, 2) motivational conversation for high-risk hypertensive individuals, 3) Follow-up of all hypertensive individuals on improving blood pressure (BP) as a primary outcome and other cardiovascular risk factors as a secondary outcome, and 4) discounts on FDC antihypertensive medication Usual care: The participants attending polyclinics randomized to usual care will continue to receive treatment from the health providers according to existing practices. The hypertensive individuals will also continue to pay for the services (physician or nurse consultation) as per their existing model of reimbursement. Participants: A total of 1000 participants will be recruited, 125 from each of the 8 polyclinics. Recruitment will be in batches of 4 and 4 clinics sequentially (balanced by randomization group). Outcomes: All hypertensive individuals will be assessed by trained outcomes assessors independent to treatment at baseline, 1-year and 2-yeat post randomization. The primary outcome will be the change in systolic blood pressure from baseline to 2 years. Primary Cost-Effectiveness measures will be- 1) Incremental cost per mm Hg systolic BP reduction from baseline to end of follow-up at two years post randomization; 2) incremental cost per projected CVD disability adjusted life years (DALYs) averted and quality adjusted life years (QALYs) saved, and 3) incremental cost per change in cardiovascular risk score from baseline to final follow-up at two-year post. The impact of effect on adherence to antihypertensive and lipid medication will be measured using data on adherence obtained from polyclinic pharmacy records and clinic notes. An average of percent adherence to antihypertensive and lipid lowering will be computed as a composite score. The change in percent composite adherence to antihypertensive and lipid medications from baseline to follow up will be compared between the intervention and control groups.
