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 well-established role of vascular endothelial growth factor (VEGF) in carcinogenesis and tumor angiogenesis has led to the development of agents that target this pathway. Anti-VEGF agents the VEGF monoclonal antibody bevacizumab, and the small molecule VEGF receptor tyrosine kinase inhibitors. Angiogenic factors play a key role in the maintenance of lung integrity and normal endothelial function. Endothelial dysfunction has been implicated in hypertension, proteinuria and retinopathy. One of the major issues of anti-VEGF agents is its long-term toxicity especially taking into account the lack of adequate knowledge in this area and the possibility of prolonged periods of therapy in non-progressing patients. Hypertension and proteinuria are commonly seen in patients treated with anti-VEGF agents. In addition, the investigators have also observed in a relatively high frequency of pulmonary air-filled lesions in patients with malignancy in the lung treated with an anti-VEGF agent. Objectives of this exploratory study are to 1) determine the effect of anti-vascular endothelial growth factor (VEGF) on endothelial function 2) determine endothelial dysfunction as a marker of early response and as an indicator for the development of hypertension and proteinuria 3) characterize the effect of anti-VEGF therapy on the pulmonary function of patients with malignancy (primary or secondary) involving the lung in patients treated with anti-VEGF agents. Pharmacodynamic endpoints to be assessed are: blood pressure, brachial artery reactivity, retinal microvessels, microalbuminuria and proteinuria, pulmonary function, assess the effects of anti-VEGF therapy by assessing brachial artery reactivity, retinal vasculature and pulmonary function in a subset of patients receiving anti-VEGF therapy. The development of markers of endothelial dysfunction may result in the early identification of patients who are non-responders or develop toxicity from anti-VEGF treatment.
The purpose of this study is to investigate the time course of PF-04764793 concentration in the blood following dosing by oral inhalation from dry powder inhalers.
The aims of this proposed community-based randomized controlled trial are to evaluate the effectiveness of nutritional, physical exercise and cognitive training interventions for at-risk and frail elderly, to elucidate the biological determinants and changes associated with frailty, and to develop, evaluate and demonstrate the feasibility of screening instruments for frailty.
This is a single-center study, randomized, Investigator/Evaluator-blinded bilateral (split-face) comparison. The objective: To assess the benefit of the concomitant use of a Moisturizing Lotion in reducing the skin irritation induced by a adapalen gel treatment in Chinese Subjects.
This clinical pharmacology research study will assess the safety and pharmacokinetics of the drug everolimus in patients with impaired hepatic function as compared to healthy volunteers.
In this open-label multicenter study the long-term effect of Pegasys monotherapy on pharmacodynamic HBV-related markers will be investigated in patients with chronic hepatitis B. Eligible patients will have completed treatment on another donor protocol (e.g. PP22512) and will receive Pegasys at an appropriate dose based on the standard of care (180mcg sc once weekly) for up to 48 weeks. Target sample size is <100.
This open-label, randomized, parallel-arm study will assess the early immunologic response in treatment-naïve Asian male patients with chronic hepatitis B after initiation of treatment with Pegasys or tenofovir or Pegasys plus tenofovir. Patients will be randomized to one of 4 cohorts to receive either Pegasys (360mcg subcutaneously weekly) or tenofovir (300mg orally daily) or both or no treatment for 2 weeks. After 2 weeks on study treatment, patients may opt to receive standard of care treatment with Pegasys. Target sample size is <50.
The goals of this study are to evaluate the safety and tolerability of multiple ascending doses of PF-04455242 administered orally to healthy adult subjects. In addition, the plasma and urine pharmacokinetics of multiple ascending doses of PF 04455242 administered orally to healthy adult subjects will be evaluated. Finally, the effect of multiple-doses of PF-04455242 on serum prolactin concentration will be explored.
This is a phase 1b, open-Label study of sorafenib with BIIB022 in subjects with advanced hepatocellular carcinoma.
This study will investigate the safety and efficacy of an investigational drug, PF-04171327 on the signs and symptoms of rheumatoid arthritis in patients that require glucocorticoids while on background methotrexate. This study will also look at the response of chemical and biological markers in rheumatoid arthritis patients. Lastly, this study will measure the PK (amount of drug in the blood) of methotrexate while patients may be taking PF-04171327.
