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.
To review the characteristics and treatment of gastrointestinal tumours at the two tertiary centres in Singapore
We hypothesize that Epidermal growth factor receptor tyrosine kinase inhibitors modulate tumor changes that may be reflected in the alteration of serum proteins. Study objectives are: - To establish serum proteomic changes in patients with non-small cell lung cancer (NSCLC) receiving erlotinib or gefitinib. - To identify a serum protein profile that predicts erlotinib or gefitinib sensitivity or resistance in NSCLC patients with and without EGFR mutations. - To study the toxicity of erlotinib or gefitinib by correlating clinical toxicity with serum protein profile.
To define the frequency of T regulatory cells in peripheral blood of RCC patients before and after nephrectomy. Study hypothesis: That nephrectomy results in a normalisation of peripheral blood T regs in early stage RCC, and a lowering of T regs in advanced RCC.
Primary 1. To determine the presence and frequency of novel and known UGT1A6 and UGT2B7 polymorphisms in healthy Chinese, Malay and Indian subjects. 2. To determine the presence and frequency of novel and known UGT1A6 and UGT2B7 polymorphisms in Chinese lung cancer patients with squamous cell and adenocarcinoma subtype. 3. To analyze the functional variations in UGT1A6 and UGT2B7 polymorphisms. Secondary 1 To study the correlation of UGT1A6 and UGT2B7 polymorphisms with lung cancer type.
1. To demonstrate the feasibility of leukapheresis and ex vivo activation of autologous NK cells in patients with metastatic NPC 2. To demonstrate the safety of low dose systemic IL-2 in combination with escalating doses of autologous Ex Vivo Activated NK cells in patients with metastatic NPC 3. To assess immune measurements such as quantitation of regulatory T cells, EBV specific T cells, serum cytokine levels, and NK cell function after treatment with IL-2 and autologous Ex Vivo Activated NK cells
We hypothesized that subjects with CYP2D6*10 alleles may have a lower steady state levels of endoxifen due to reduced conversion of tamoxifen to endoxifen. Primary objectives: - To determine the steady state pharmacokinetics of tamoxifen and its metabolites - To test the effects of genetic polymorphisms of CYP2D6 on plasma concentration of tamoxifen and its metabolites in hormone receptor positive women who are taking tamoxifen as adjuvant treatment for breast cancer.
The overall objective of the study is to assess the feasibility of the use of blood for the detection of EGFR mutations in patients with non-small cell lung cancer (NSCLC) Specific aims are: 1. To assess the use of immuno-separation techniques to enrich the tumor cell population in the blood of NSCLC patients. 2. To assess the use of denaturing high performance liquid chromatography (DHPLC) assay for the detection of EGFR mutations in the blood of NSCLC patients.
This study is designed to determine the clinical efficacy and toxicity of ABT-869 in combination with carboplatin and paclitaxel in the treatment of subjects with advanced or metastatic NSCLC.
Anti-angiogenic targeted therapies are used in a wide range of solid tumors including NSCLC, breast cancer, GISTs, CRC, renal cell carcinoma and hepatocellular carcinoma. Somatic mutations in genes related to tumorigenesis have been associated with treatment response whereas germline gene variants have been associated with tumor risk, prognosis and treatment related toxicity.Study objectives are: 1. To characterise the prevalence and clinicopathological associations of germline and somatic variation in genes involved in the angiogenic pathway in healthy donors and unselected cancer patients 2. To examine the association between angiogenic gene variants and outcome in patients receiving anti-angiogenic therapy
The proposal seeks to establish: - A comprehensive compilation (database) of clinical information comprising clinical, histopathological, treatment and follow-up characteristics of past and future gastrointestinal cancer (GIC) cases in Singapore that can be shared by investigators. The characteristics will include clinical (eg age, sex, stage), histopathological (eg. grade, type), treatment (eg. treatment status, regimens) and outcome data (eg. survival, toxicity) from medical records. - A collection (bank) of corresponding frozen and fixed tissue, blood and processed samples (enriched blood mononuclear cells, protein, RNA, DNA, tissue arrays) in Singapore that can be shared by the investigators. - A gastrointestinal cancer co-operative group (GCCG) of clinicians and scientists researching prognostic and predictive markers in GIC, which will benefit from the multi-disciplinary knowledge, information and samples of its members. - To characterise genetic polymorphisms related to Gastrointestinal cancer chemotherapy treatment in controls (healthy volunteers)
