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 primary objective of this study is to compare the efficacy, safety, and tolerability of tenofovir alafenamide (TAF) versus tenofovir disoproxil fumarate (TDF) in treatment-naive and treatment-experienced adults with hepatitis B e antigen (HBeAg)-positive chronic hepatitis B virus (HBV) infection.
The purpose of this study Part A is to determine the safety, tolerability and the pharmacokinetics of BAY1143572 in subjects with advanced malignancies, which are either refractory to or ineligible for treatment with standard agents. The purpose of this study Part B is: Determine the safety, tolerability, pharmacokinetics (PK) and maximum tolerated dose (MTDG-CSF) of BAY1143572 with concurrent administration of the granulocyte colony-stimulating factors (G-CSF) in an intermittent and continuous dosing schedule in subjects with advanced malignancies.
This study will collect data of patients who are treated with TACE followed by sorafenib for hepatocellular carcinoma (HCC) or patients without Sorafenib after TACE. In contrast to a prior observational study on sorafenib (GIDEON study), where pre-treatment with TACE was documented retrospectively, this study will collect more detailed information about the TACE treatment and the status of a patient when treatment with sorafenib is started.
Conjunctivochalasis refers to loose redundant, non-edematous inferior conjunctiva that is situated between the globe and lower eyelid, and usually it occurs bilaterally. It has been reported to cause ocular discomfort, tear instability, alteration of tear spreading and subsequently dry eye, which is a common condition that affects vision and quality of life in patients. This condition has also been reported to be associated with aging and ocular surface inflammation. The assessment of conjunctivochalasis was traditionally based on silt lamp examination and this may be cumbersome and highly subjective. Only recently, researchers have advocated the use of imaging and more objective documentation by anterior segment optical coherence tomography (AS-OCT), using Fourier-Domain RTVue-100 OCT. The AS-OCT is an imaging method that documents the tear meniscus and prolapse of conjunctiva into the tear meniscus in a safe, rapid and non-invasive way. Image analysis on the area of prolapsed conjunctiva can then be used to ascertain the severity of conjunctivochalasis. We propose the use of HD-Cirrus AS-OCT for the imaging of conjunctivochalasis, since this technique provides more magnified and colored digital images, which helps to delineate different tissues and serves as a better education tool for patients. This current study aims to investigative the inter and intra examiner reproducibility of imaging conjunctivochalasis using HD-Cirrus AS-OCT, using patients from the dry eye clinic from the Singapore National Eye Centre. These patients will be asked to come to the centre for imaging and have three scans of the same eye performed in one session by two trained investigators consecutively. The resulting limits of repeatability will be very useful for us to follow up patients who undergo surgical or diathermy treatment for conjunctivochalasis, and for sample size calculation in the planning of interventional studies.
Dry eye clinical research is limited to follow up of disease progression. While a large catalogue of tests, such as corneal staining grading, tear break up time (TBUT) and Schirmer's test, is available, objective assessments demonstrate poor to moderate repeatability. Among these assessments, TBUT has the best repeatability while the Schirmer's test shows good repeatability for more severe forms of the disease.1 As such, currently, most research outcomes are based on subjective patient complaints rather than objective assessment of the condition. LipiView Ocular Surface Interferometer (LipiView) is a HSA-approved imaging device that has the ability to assess optical interference pattern produced by light reflected off the tear film in a safe and non-invasive manner.2 Software analysis of the image then measures the tear LLT, which is used to objectively quantify the diagnosis of lipid-deficient dry eye. This current study aims to investigative the inter and intra-examiner reproducibility of measuring tear lipid layer thickness (LLT) with LipiView, which is used in our current clinical setting. LipiView has not been evaluated on its reproducibility of measuring tear lipid layer thickness. The study will also assess for correlation between the magnitude of tear LLT and the inter and intra-examiner reproducibility of LipiView. Once this method is found to be repeatable, this can be used in future clinical settings and trials as an additional tool to investigate dry eye treatments.
Patients with Chronic Hepatitis B on long term oral antiviral therapy have to continue treatment indefinitely unless they achieve HBeAg seroconversion or HBsAg seroclearance, when therapy can be stopped. While HBeAg seroconversion is a more achievable endpoint, only 20-25% of patients develop this after one year of oral antiviral therapy. HBsAg seroclearance is universally infrequent. Strategies to improve these endpoints such as combination oral antiviral therapy have not been generally successful and recently studies have examined the possibility of switching or adding peginterferon therapy. However these have not been tested adequately in the group of patients that have been on long term oral antiviral therapy. Consequently this study was conceived to evaluate whether switching or adding peginterferon compared to continuing oral antiviral therapy are more efficacious strategies. HBeAg positive and HBeAg negative patients (n=310)will be randomised to continue oral antiviral therapy, switch or add pegylated interferon for 48 weeks in a ratio of 1:2:2 respectively. The study endpoints are HBsAg seroclearance, reduction of qHBsAg >1 log, qHBsAg<200 IU/ml, HBeAg loss and seroconversion, and HBV DNA suppression, all at week 72.
To study the safety and efficacy of the combination of BGJ398 with BYL719 in patients whose tumors express mutations to PIK3CA with or without alterations to FGFR 1-3.
Heart failure (HF) is a major global public health issue which also affects Asia. Data from the National Registry of Disease in Singapore shows a 9.4% rise in HF admissions in public hospitals from 2008 to 2009 (4140 to 4530). Anaemia (low blood Haemoglobin level) is a common problem occurring in HF, ranging from 14% to 56% in outpatient registries and clinical trials. Anaemia exacerbates the basic symptoms of HF of dyspnea and exercise intolerance, thereby reducing quality of life (QoL). However, recent approaches aimed at improving and normalizing Haemoglobin have been unsuccessful.Novel approaches are required to address this problem. Iron deficiency (ID) is a well-understood cause of anaemia. ID without overt anaemia may be present in HF patients. A recent study by Jankowska et al published in 2010 of 546 HF patients showed a 37% prevalence of ID, regardless of Haemoglobin level. This was associated with worse outcomes including impaired exercise capacity. The presence of ID indicates a higher likelihood of deteriorating and dying early. A landmark study published in the New England Journal of Medicine (The Ferinject Assessment in Patients with Iron Deficiency and Chronic Heart Failure (FAIR-HF) study) showed that HF patients who were treated with IV iron in the form of Ferric Carboxymaltose (FCM) had better outcomes, including improved exercise capacity, overall function, and quality of life. There is a lack of contemporary data on ID in HF patients in Asia, including data on treatment with this novel IV iron FCM. Hypothesis We hypothesise that treating ID in HF patients in Asia using FCM will improve outcomes including exercise capacity, quality of life, overall functional status, and the need to be hospitalised for complications arising from HF.
The purpose of this study was to evaluate the effect of LCZ696 compared to valsartan in the reduction of cardiovascular death and heart failure(HF) hospitalizations in patients with HF with preserved ejection fraction.
