There are about 1320 clinical studies being (or have been) conducted in Saudi Arabia. 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.
This study will evaluate the safety and efficacy of Dovitinib versus sorafenib in patients with metastatic renal cell cancer.
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known whether radiation therapy is more effective when given together with chemotherapy or alone after surgery in treating salivary gland tumors. PURPOSE: This randomized phase II/III trial is studying radiation therapy with or without chemotherapy to see how well it works in treating patients with high-risk malignant salivary gland tumors that have been removed by surgery.
Research Problem Asthma is one of the most common chronic diseases in the world that affects approximately 300 million individuals worldwide. It is characterized by airway inflammation and bronchoconstriction leading to airflow obstruction, however, the triggering factors behind asthma development remains to be elucidated. Genetic risk factors have been suggested to play a central role in asthma development. Twin studies supported a strong genetic component to asthma, especially childhood asthma, with heritability estimates suggesting that 48-70% of asthma risk is attributed to genetic risk factors. Suggestive susceptibility genes have been identified in European and American populations but not yet in the Middle East including Saudi Arabia. Identified genes whether they are polymorphic variants of genes encoding known pathophysiological molecules or novel genes identified by linkage or genome-wide association studies (GWAS) are inconsistent in different populations thereby adding to the need to undertake genetic studies on different ethnic populations and in different countries. Here, the investigators hypothesize that polymorphic variation of novel susceptibility genes form a major risk factor for asthma development, response to treatment and progression in the Saudi population with strong diagnostic, prognostic and therapeutic implications. Research Significance Since the manifestation of complex inflammatory disorders with strong heritability is complex involving genetic and environmental interaction, each ethnically distinct population must be examined to know whether gene-disease association exists in that population. The objectives of this proposal are to discover novel asthma susceptibility genes in the Saudi population. A better understanding of the genetic mechanisms of asthma will enhance our knowledge of its pathophysiology. Asthmatic patients with distinct genotypes respond differently to asthma medications. Therefore, improvements in diagnostics and pharmacogenetics may be the first clinical developments of these extensive studies. This embraces the concept of asthma subphenotypes and stratified medicine where interventions are targeted at those individuals who will best benefit from them with minimal side effects. Physicians looking after asthmatic patients will be able to provide better medical service tailored to those patients, as well as to identify Saudi people at high risk for the development of asthma, especially the more severe forms of the disease. Research Objectives The main objective of our proposal is to identify known and novel asthma susceptibility genes in the Saudi population and to investigate their interaction with clinical, environmental, and inflammatory factors contributing to asthma pathophysiology. Research Methodology In this proposal, the investigators will investigate the genetic factors contributing to asthma susceptibility by determining in Saudi population, the presence of single nucleotide polymorphisms (SNPs) that have been previously reported from linkage and GWAS in other populations. Whole genome DNA will also be scanned for novel SNPs of selected "asthma genes" using microarrays. This will enable us to identify new SNPs that contribute to the risk of asthma specifically in the Saudi population. In addition, the investigators will cross-reference all genetic and immunological parameters with the corresponding clinical data in order to elucidate the impact of certain genes, or their products (e.g. cytokines), on the clinical manifestation of asthma.
This study aims to determine the prevalence of human papillomavirus (HPV) and to assess the HPV type distribution among women >= 15 years of age, attending routine gynaecological examination in the Kingdom of Saudi Arabia.
The purpose of this study is to demonstrate the feasibility of pacing as a therapy to prevent adverse remodeling of the myocardium following an acute myocardial infarction (MI) in patients at highest risk for adverse myocardial remodeling.
Renal cell carcinoma (RCC) accounts for more than 200,000 new cases of cancer and over 100,000 cancer deaths annually in the World (Ferlay, et al., 2004). It is estimated that there were about 15,000 new cases of RCC in the region that excludes the Americas, European Union and Japan. Renal cell carcinomas arise from the proximal tubal epithelium are more common in males than in females with an overall lifetime risk of 1 in 75 and a median age of diagnosis of 65 years. Everolimus (Certican®) has been approved since 2003 in more than 60 countries for the prevention of organ rejection in patients with renal and cardiac transplantation. Everolimus (RAD001) is a derivative of rapamycin, which acts as a signal transduction inhibitor. It targets mTOR, a key protein kinase regulating cell growth, proliferation, and survival. The mTOR pathway activity is modulated by the phosphatidylinositol-3-kinase (PI3K)/protein kinase B AKT (AKT) pathway, a pathway known to be deregulated in numerous human cancers. RAD001 (Afinitor®) has been investigated as an anticancer agent based on its potential to act: - directly on the tumor cells by inhibiting tumor cell growth and proliferation; - indirectly by inhibiting angiogenesis leading to reduced tumor vascularity (via potent inhibition of tumor cell hypoxia-inducible factor 1 (HIF-1) activity, VEGF production, and VEGF-induced proliferation of endothelial cells). Primary: To evaluate the PFS rate over time. Secondary: - To evaluate the disease control rate (stable disease [SD] + partial response [PR] + complete response [CR]); - To evaluate the objective response rate (ORR; where ORR = CR + PR) and duration; - To describe the safety profile of RAD001.
