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 purpose of this study is to define cut-off values of the most widely used composite scores and patient-reported outcomes, for levels corresponding to remission/low disease activity and for changes in levels corresponding to flares, in PsA, when remission/low disease activity and flare are defined from the patient and physician perspective. The ReFlaP (Remission/Flare in PsA) study is a prospective, multicentric international, longitudinal, observational study.
Polypoidal choroidal neovasculopathy (PCV) is a subtype of wet age related macula degeneration (AMD) occuring more commonly in the Asian population. Besides the phenotypic differences, PCV is thought to have a lesser response to anti VEGF therapy which is the mainstay of treatment for other typical wet AMD. Recent trial data suggest that a combination with photodynamic therapy may help in the visual and anatomical outcome of PCV, and emerging evidence shows favourable outcomes the newer anti VEGF agent, aflibercept 2mg monotherapy. These trials however, have assessed aflibercept in a strict 2mg every 8 weekly regime. In the clinical setting, a significant an unmet need in the management of PCV is a tailored treatment regime. Here we propose a treatment regimen based on disease activity for PCV with aflibercept mono therapy. A limitation of the 2q8 regime is that it is fixed and does not vary regardless of polyp closure or anatomical outcome at the first time point of assessment (month 3). We hypothesize that after the initial 3 monthly injections of aflibercept, about 50% of PCV will close and become quiescent, and in the remaining 50%, a further 3 monthly injections will increase overall polyp closure rate. After a loadings phase of either 3 or 6 months, all eyes will start on a treat and extend regime (T&E), with a minimum period of 8 weeks and a maximum of 12 weeks between treatments with 2 week increments if PCV remains quiescent. The proposed study aims to evaluate the efficacy of a modified treat and extend regime based on disease activity with aflibercept monotherapy for PCV.
Since the 1st pandemic of the 21st century caused by SARS coronavirus, the world has experienced outbreaks of swine origin H1N1 influenza, Ebola and Zika viruses, which have all resulted in global health crises. Rapid mass vaccination with an effective vaccine such as a live attenuated vaccine, of vulnerable immune-naïve populations to establish herd immunity is an approach to control outbreaks. Such live attenuated vaccine had been used with great success in sporadic yellow fever outbreaks and recently successfully employed in Ebola field trial, both of these diseases have the potential for pandemic spread. Indeed, live attenuated vaccines have proven especially effective in controlling childhood diseases and have even succeeded in eradicating polio and measles from most parts of the world. However, deployment of such vaccines for pandemic control cannot be limited to children but must include adults in order to rapidly elevate herd immunity rates to halt transmission. Vaccinating adults may produce efficacy rates significantly different to those observed in children due to the prevalence of chronic diseases and their associated metabolic complications. Presently, there are 1 billion people who are overweight, many suffer from concurrent metabolic disorders. As activation of the adaptive immunity is reliant on a robust innate immune response to vaccines, metabolic disorders and long-term anti-inflammatory therapy with interventions such as statins may reduce vaccine immunogenicity resulting in suboptimal efficacy in this subpopulation. This study would therefore test the hypothesis that statins reduce live attenuated vaccine immunogenicity. We will combine a clinical trial with systems vaccinology approaches to define the impact statins has on the innate immune, B and T-cell responses to live attenuated vaccination. Our study will thus extend upon another recently completed trial by us and will provide new insights into the determinants of vaccine efficacy in a rapidly growing and aging population globally
This research study is carried out to examine the effects of Phosphatidylserine-Omega 3 supplements (i.e., Vayarin) among children with Autism Spectrum Disorder (ASD) and ADHD. Participants will be randomised either to receive the Vayarin treatment (Intervention group) or to a Control group.
The aim of this trial is to evaluate the safety of single doses of a study drug known as LY3325656 that is given orally to healthy participants and participants with type 2 diabetes. Information about any side effects that may occur will be collected. It will also investigate how much of the study drug gets into the blood stream, and how long it takes the body to get rid of it. The study consists of two parts. Part A will study healthy participants over approximately 12 weeks and Part B will study participants with type 2 diabetes over approximately 5 weeks, excluding screening. Screening is required within 28 days of the start of the study.
This study is a prospective, randomized, non-blinded study. 1 group will be assigned the standard arm with use of heparinised saline (10U/ml) lock in between each catheter use. This is consistent with the standard procedure of PICC care in the investigators' centre. The second group will be assigned the intervention with use of 4% citrate lock (Dirinco Citra-Lock 4%) in between each catheter use.
The purpose of this study is to better understand the linkages between family health history (FHH) and genomics in a Singaporean population. Secondly this study will evaluate the facilitators and barriers to implementation of a family history collection and risk assessment tool within a Singaporean population.
The purpose of this first in human (FIH) trial is to characterize the safety and tolerability of the SHP2 inhibitor TNO155 alone and in combination with EGF816 (nazartinib) and identify a recommended dose for future studies in adult patients with advanced solid tumors in selected indications.
Endoscopic ultrasound guided fine needle aspiration (EUS-FNA) is the technique of choice to evaluate solid gastrointestinal (GI) lesions. The tissue acquired using this technique is essential for diagnosis of diseases like sub-mucosal masses (GIST), lymphoma, autoimmune pancreatitis and pancreatic cancer. Also the availability of adequate tissue will enable performance of molecular profiling and personalized oncologic therapy. The current needle used for tissue acquisition rarely provides tissue blocks needed for histology assessment. Hence, a better needle device with a good safety profile is needed to solve this technical difficulty. The new AcquireTM fine needle biopsy device could over come this difficulty because of its unique designs. The additional cutting edge surface allows better tissue access and provides core tissue (>90%) for histology. The safety profile of this new device is comparable to the conventional FNA needle thereby making it an ideal device for tissue acquisition.
This proposal translates a hypothesis driven basic research into clinical setting to determine the potential of using autologous CD133+ cells to reverse fibrosis and improve clinical outcome for patients with end stage cirrhosis. This has significant impact on the management of cirrhosis.
