NCT ID: NCT00565708 Active, not recruiting - Colorectal Cancer Clinical Trials

Aspirin for Dukes C and High Risk Dukes B Colorectal Cancers

ASCOLT
Start date: December 2008
Phase: Phase 3
Study type: Interventional

We hypothesize through this randomized, placebo-controlled adjuvant study, that Aspirin in patients with dukes C or high risk dukes B colorectal cancer (ASCOLT) can improve survival in this patient population over placebo control. If indeed found to be beneficial, because aspirin is cheap and easy to administer, it will positively impact the lives of many individuals in Asia and globally. STUDY OBJECTIVE To assess the effectiveness of Aspirin against placebo control in patients with dukes C or high risk dukes B colorectal cancer in terms of Disease Free Survival (DFS) and Overall Survival (OS) Primary endpoints - DFS among all eligible subjects (high risk Dukes B colon cancer, Dukes C colon cancer and rectal cancer patient sub-groups); - DFS among patients with colon cancer (high-risk Dukes B and Dukes C colon cancer). Secondary endpoints - Overall survival (OS) over 5 years - DFS and OS in - Chinese, Malay, Indian and other ethnic groups - Resected high risk Dukes B colon cancer, Dukes C colon cancer and rectal cancer sub-groups, individually - Compliant versus non-compliant subjects - PIK3CA mutated tumors (where samples are available)

NCT ID: NCT00470236 Active, not recruiting - Clinical trials for Carcinoma, Ductal, Breast

Radiation Doses and Fractionation Schedules in Non-low Risk Ductal Carcinoma In Situ (DCIS) of the Breast

DCIS
Start date: June 2007
Phase: N/A
Study type: Interventional

Hypotheses: 1. The addition of tumour bed boost after BCS in women with non-low risk DCIS reduces the risk of local recurrence (invasive or intraductal recurrence in the ipsilateral breast). 2. The risk of local recurrence in the shorter fractionation arm is not worse than that for the standard fractionation arm. 3. A molecular signature predictive of invasive recurrence of DCIS will be detectable and the molecular signature may eventually have clinical utility for therapy individualization. Overall Objectives: 1. To improve the outcome of women with non-low risk DCIS treated with breast conserving therapy. 2. To individualize treatment selection for women with DCIS to achieve long term disease control with minimal toxicity.

NCT ID: NCT00429611 Active, not recruiting - Clinical trials for Ventricular Fibrillation

High Low Biphasic Energy Defibrillation (HiLoBED)

Start date: November 2004
Phase: Phase 3
Study type: Interventional

This inhospital study aims to compare the efficacy of high-versus low-energy biphasic shocks in order to determine the optimal level for defibrillation. Time is the essence when attending to a VF patient. Hence, it is important to determine the optimal amount of defibrillation energy that should be delivered at first shock, thereby increasing the patient's chances of survival. In addition, this study provides an opportunity to evaluate the impact on myocardial integrity/function of different levels of defibrillation energy in an inhospital clinical environment.

NCT ID: NCT00416130 Active, not recruiting - Breast Cancer Clinical Trials

Clinical Trial of SAHA in Patients With Breast Cancer

Start date: January 2007
Phase: Phase 1/Phase 2
Study type: Interventional

Purpose: - evaluate the safety of Vorinostat. - evaluate the effectiveness of Vorinostat in treating breast cancer - evaluate how the study subject's body reacts to Vorinostat, how these reactions relate to the subject's genes, and whether protein changes in the subject blood may be used to predict how the subject's cancer will respond to Vorinostat We hypothesize that Vorinostat, as a novel class of anti-cancer agents, may induce response in patients with recurrent or metastatic breast cancer who have been previously treated with anthracyclines and taxanes. In addition, we hypothesize that serum Vorinostat levels may correlate with clinical response and toxicities, and that Vorinostat may induce unique protein changes in the plasma in responding patients, and that these proteins may in turn be used as predictive biomarkers for treatment response.

NCT ID: NCT00371124 Active, not recruiting - Myopia Clinical Trials

Safety and Efficacy Study of 0.5%, 0.1% & 0.01% Atropine Treatment to Both Eyes In Treatment of Myopia In Children

Start date: March 2006
Phase: Phase 2/Phase 3
Study type: Interventional

The purpose of this study is to find an optimal dose of atropine for preventing the rapid progression of myopia in children by comparing the efficacy, safety and functional impact of binocular treatment with 0.5%, 0.1% and 0.01% atropine and to develop a treatment regimen for the routine management of childhood myopia.

NCT ID: NCT00336063 Active, not recruiting - Clinical trials for Adult Nasal Type Extranodal NK/T-Cell Lymphoma

Vorinostat and Azacitidine in Treating Patients With Locally Recurrent or Metastatic Nasopharyngeal Cancer or Nasal Natural Killer T-Cell Lymphoma

Start date: March 3, 2006
Phase: Phase 1
Study type: Interventional

This phase I trial studies the side effects and best dose of vorinostat when given together with azacitidine in treating patients with nasopharyngeal cancer or nasal natural killer T-cell lymphoma that has recurred (come back) at or near the same place as the original (primary) tumor, usually after a period of time during which the cancer could not be detected or has spread to other parts of the body. Drugs used in chemotherapy, such as vorinostat and azacitidine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Vorinostat and azacitidine also may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving vorinostat together with azacitidine may kill more cancer cells.

NCT ID: NCT00324493 Active, not recruiting - Hemophilia Clinical Trials

Musculoskeletal Function in Hemophilia

Start date: June 2004
Phase: N/A
Study type: Observational

Hemophilia, which results from deficiency of factor VIII or IX, is a common hereditary X-linked bleeding disorder affecting up to 10/100,000 population. About 60-70% of them have severe disease (factor level <1%). This group is characterized by the occurrence of frequent spontaneous bleeding into joints and soft tissues. If inadequately treated, it results in progressive damage to joints and muscles leading to crippling deformities. Close clinical observation of these patients over many years has shown that those with >1% levels have much less bleeding compared to those with less than 1%. This observation has gained immense clinical importance in planning therapy for these patients. To prevent progressive joint damage, the missing factor needs to be replaced. Much has evolved in this practice in the last 50 years. From administration of whole blood in the beginning, to plasma and cryoprecipitate, to purified plasma-derived concentrates and finally recombinant factor concentrates. The standard of therapy now is to replace factors frequently enough to maintain >1% factor levels at all times (“prophylaxis”) or administer immediately on premonition or earliest signs of bleeding (“on demand” therapy). This has greatly enhanced the quality of life of people with hemophilia. However, the optimal regimens of factor replacement remain to be defined. The definition of what is optimal management of this chronic condition, currently incurable for the vast majority of patients, varies significantly in different parts of the world, depending on practicality and social expectations. Models have care have been developed in Western countries based on careful documentation of outcome over many years. Such data is lacking from developing countries. This multi-center study aims to systematically record the outcome of musculoskeletal function in people with hemophilia in developing countries for the first time and provide information that can help plan care for the 80% of all hemophiliacs in the world who live in these countries. Currently there is no well documented model of care at the range of factor replacement practiced in these countries nor is there any significant information on the long-term outcome of musculo-skeletal function among these patients.

NCT ID: NCT00282100 Active, not recruiting - Liver Cancer Clinical Trials

Adjuvant Therapy of Gefitinib (Iressa, ZD1839) in Patients With Resectable Hepatocellular Carcinoma

Start date: December 2005
Phase: Phase 2
Study type: Interventional

This research is being done to find how soon the liver cancer may come back and whether proteins or genes in tumor, blood or urine can give us clues of early recurrence.

NCT ID: NCT00262067 Active, not recruiting - Clinical trials for Metastatic Breast Cancer

Start date: December 2005
Phase: Phase 3
Study type: Interventional

This is a Phase III, multicenter, randomized, placebo-controlled trial designed to evaluate the efficacy and safety of bevacizumab in combination with chemotherapy compared with chemotherapy alone in subjects with previously untreated metastatic breast cancer.

NCT ID: NCT00247260 Active, not recruiting - Liver Cancer Clinical Trials

Safety of 32P BioSilicon in Patients With Hepatocellular Carcinoma

Start date: October 2005
Phase: Phase 2
Study type: Interventional

Brachytherapy is a recent technique used in the treatment of tumours and involves the use of radioactive sources brought into close contact with the target tissues. One of the principal benefits of brachytherapy is that high radiation doses can be localised within the tumour with the consequence of minimal side effects. 32P is a radionuclide ideal for brachytherapy as it has high energy beta emitting properties, typically a maximum tissue range of about 8 mm and a half life of 14.3 days. 32P BioSiliconTM is an active implantable medical device encapsulating 32P within the internal microcrystalline structure of highly pure inert silicon and acts as a sealed source for the provision of 32 phosphorous. Tumours targeted with 32P BioSiliconTM are hypothesized to show a reduction in volume with a low incidence of side effects associated with the treatment. Prolongation of survival and improved quality of life would be favourable outcomes of the investigational product.
