NCT ID: NCT03267641 Completed - Clinical trials for Hepatocellular Carcinoma

Prospective Cohort Study on the Clinical Trajectory of Resected Hepatocellular Carcinoma

PLANET
Start date: May 16, 2016
Phase:
Study type: Observational

Hepatocellular carcinoma (HCC) is the 6th most common cancer in the world but the 2nd most important cause of cancer death. Because of its highly heterogeneous nature, the current approach to identifying druggable targets have not delivered efficacious therapies in HCC and is a main reason for the high case fatality. Even when surgical resection is potentially curative in early disease, tumor recurrence remains high and long term survival poor because of the absence of useful adjuvant therapy. To address these unmet needs, the investigators bring together internationally recognized scientists from genomics and immunology and established clinician investigators in a synergistic team. This TCR capitalizes on recent collaborative advances made by the PIs in the consortium. The investigators have shown through multi-region sampling of freshly resected HCC and phylogenetic analysis, that significant intra-tumoral heterogeneity exists and have identified the specific positions of known clonal drivers. Simultaneously the investigators have analyzed the immune landscape of the tumor microenvironment with deep immune-phenotyping and found unique inter-patient immune landscapes predictive of clinical trajectory. This TCR is a prospective study that samples resected HCC from multi-ethnic sites within the established Asia-Pacific Hepatocellular Carcinoma (AHCC) Trials Group, which has enrolled approximately 1000 patients through 6 multi-center trials in 35 centers in the region. Clinical trajectories are tracked and genomic and immunological studies are repeated when tumors recu r, to confirm clonally dominant driver mutations and immunological processes that are targetable. Concurrently, representative pre-clinical models will be developed from the tissues sampled. The investigators aim to combine these approaches to overcome the challenges posed by genomic heterogeneity and to guide the development of therapeutics and precision medicine in HCC.

NCT ID: NCT03267498 Active, not recruiting - Clinical trials for Nasopharyngeal Carcinoma

Nivolumab + Chemoradiation in Stage II-IVB Nasopharyngeal Carcinoma (NPC)

Start date: February 14, 2018
Phase: Phase 2
Study type: Interventional

This phase II trial studies how well nivolumab and chemoradiotherapy works in treating patients with stage II-IVB nasopharyngeal cancer. Monoclonal antibodies, such as nivolumab, may block tumor growth in different ways by targeting certain cells. Chemoradiotherapy is the combination of chemotherapy and radiation therapy and may prevent the cancer from spreading when combined with nivolumab. Giving nivolumab and chemoradiotherapy may work better in treating patients with stage II-IVB nasopharyngeal cancer.

NCT ID: NCT03266237 Completed - Influenza Clinical Trials

The Immune Response to Influenza Vaccinations in Elderly Individuals

Start date: December 2013
Phase: Phase 4
Study type: Interventional

The aim of this study is to characterize the immune profile of frail and healthy aged individuals and investigate their immune responsiveness including the response to influenza vaccine over an 18-month period. The project will include a longitudinal study to define immune signatures and multi-parameter profiles associated with frailty and may lead to the identification of predictive markers of evolution to frailty and Immunosenescence in the elderly.

NCT ID: NCT03264001 Active, not recruiting - Insulin Resistance Clinical Trials

Effects of Progressive Negative Energy Balance on Glucose Tolerance, Insulin Sensitivity, and Beta-cell Function

Start date: April 4, 2017
Phase: N/A
Study type: Interventional

Type 2 diabetes results from a combination of peripheral insulin resistance and beta-cell dysfunction, and manifests as fasting and postprandial hyperglycemia. In Singapore, despite the relatively low prevalence of overweight and obesity, the prevalence of type 2 diabetes is disproportionately high and is expected to double in the near future. This indicates that insulin resistance and beta-cell dysfunction are widely prevalent even among individuals who are not overweight or obese. Still, weight loss induced by a variety of ways (calorie restriction, exercise, surgery, etc.) is considered the cornerstone of diabetes treatment. This underscores the importance of negative energy balance in improving metabolic function. In fact, negative energy balance induced by calorie restriction can improve metabolic function acutely, i.e. within 1-2 days and before any weight loss occurs. Likewise, negative energy balance induced by a single session of aerobic exercise improves metabolic function over the next few days. However, the magnitude of negative energy balance that needs to be achieved in order to improve metabolic function, as well as possible dose-response relationships, are not known. Furthermore, the comparative efficacy of calorie restriction vs. exercise in improving metabolic function has never been directly assessed. Accordingly, a better understanding of the effects of acute negative energy balance induced by calorie restriction or aerobic exercise on insulin sensitivity and beta-cell function will have important implications for public health, by facilitating the design of effective lifestyle (diet and physical activity) interventions to prevent or treat type 2 diabetes. To test these hypotheses, whole-body insulin sensitivity, the acute insulin response to glucose, and the disposition index (i.e. beta-cell function), will be determined the morning after a single day of progressively increasing negative energy balance (equivalent to 20% or 40% of total daily energy needs for weight maintenance) induced by calorie restriction or aerobic exercise. Results from this project are expected to result in the better understanding of the effects of negative energy balance induced by diet and exercise on metabolic function. Therefore, this project may help in the design of effective lifestyle intervention programs for the prevention and treatment of type 2 diabetes.

NCT ID: NCT03262935 Completed - Clinical trials for Metastatic Breast Cancer

SYD985 vs. Physician's Choice in Participants With HER2-positive Locally Advanced or Metastatic Breast Cancer

TULIP
Start date: December 15, 2017
Phase: Phase 3
Study type: Interventional

The purpose of this study is to demonstrate that SYD985 [(vic-)trastuzumab duocarmazine] is superior to physician's choice in prolonging progression free survival.

NCT ID: NCT03260218 Recruiting - Clinical trials for Postoperative Delirium

Protocol for Observational Study of Post op Delirium Following Total Joint Arthroplasties

Start date: July 3, 2017
Phase: N/A
Study type: Observational

The incidence of post-operative delirium in the South-east Asian population is not known. Through a prospective, single centre, observational study, the investigators aim to characterize the incidence and risk factors of delirium in older adults undergoing elective total joint arthroplasties (TJA). The study will recruit eligible patients (65 - 90 years old undergoing elective TJA), with a targeted sample size of 500. Patients will be screened for dementia and Confusion Assessment Method (CAM) scores obtained pre and post operatively. Other data such as preoperative Charlson comorbidity index (CCI), post op complications using Post operative Morbidity Survey (POMS), pain scores, readmission rates and length of hospital stay (LOS), functional and health-related quality-of-life (HRQoL) will also be collected and analysed.

NCT ID: NCT03258450 Completed - Clinical trials for Colorectal Neoplasms

Effectiveness of a Psychosocial Intervention for Colorectal Cancer

EPIC
Start date: November 1, 2017
Phase: N/A
Study type: Interventional

Studies have reported about one-third to half of advanced cancer patients experience psychological distress yet the mental healthcare needs of these patients are not properly assessed and addressed. Patients with advanced colorectal cancer can face unique challenges that are stoma- or bowel-related in addition to other symptom burden such as pain, fatigue, and existential distress that have deleterious consequences on their psychological and social functioning. This pilot study aims to test an intervention for patients specifically with advanced colorectal cancer that incorporates culturally-appropriate topics. Using a randomized selection design, we will investigate the feasibility and acceptability of the intervention and obtain an initial estimate of efficacy of the intervention. This pilot study will yield useful information to inform the preparation of a larger, phase III confirmatory study.
