There are about 9745 clinical studies being (or have been) conducted in Israel. 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 use of Intracytoplasmic sperm injection (ICSI) has increased in the last decades regardless of the cause of infertility. Despite the increased use there is no clear evidence that ICIS is more effective than conventional in vitro fertilization (IVF) for non-male factor infertility. The investigators therefore aim to perform a prospective randomized controlled study to compare between ICSI and conventional IVF in women between 39 to 44 years of age with non-male factor infertility.
Glucocorticoids (GCs) are a class of endogenous steroid hormones produced by the adrenal glands and controlled by the hypothalamic-pituitary-adrenal axis (HPA). One of the mechanisms of their action is achieved through ligand-receptor attachment to a class of cytosolic steroid hormone receptors termed Glucocorticoid Receptors (GRs). The formed ligand-receptor complex is a transcription factor involved in gene activation of anti-inflammatory products or repression of pro-inflammatory products [1]. Synthetic forms of GCs are a group of anti-inflammatory and immunosuppressive medications (e.g. Prednisone) that are widely used in clinical practice to treat inflammatory diseases (e.g. Rheumatoid Arthritis, Vasculitis, Asthma). The effectiveness of this class of drugs is limited by numerous adverse effects that include, but not limited to, insulin resistance, glucose intolerance, dyslipidemia, and hypertension, all of which are well known risk factors for cardiovascular diseases (CVD) [2,3]. Furthermore, recent research suggest that inflammation has a key role in development of CVD and can predict prognosis [4]. Inflammatory cells have an important role in the development of atherosclerotic lesion in the arteries. Blood monocyte-derived macrophages are involved in this process, and they infiltrate the lesion where they take up various forms of lipids (cholesterol - rich LDL, and oxidized LDL) as well as triglycerides - rich VLDL), followed by the formation of lipid-laden foam cells, the hallmark of early atherogenesis. Inflammatory cells and molecules as well as proteolytic enzymes secreted from inflammatory cells in the atherosclerotic lesion, have a central role in destabilizing the plaque (vulnerable plaque) leading to its rupture, which, in turn, induces thrombosis, and initiating acute coronary events [4,5]. Based on our understanding of the involvement of inflammation in the early development of atherosclerotic lesion, and our experience with the anti-inflammatory effects of synthetic GCs, a hypothesis emerged suggesting this class of drugs as a way to inhibit early atherosclerotic plaque formation, and to attenuate CVDs [6]. Research results in this field are surprising because while glucocorticoids treatment in humans increase the risk of CVDs [6,7,8,9], animal models shows the opposite, atheroprotection was shown in rabbits [10,11,12] and mice [13,14,15]. This paradox may be explained partially by the fact that clinical studies in this field are mainly conducted in patients with predisposing factors to develop CVD, either because of pre-existing traditional risk factors like Diabetes and Hyperlipidemia, or because of the pre-existing medical condition they are being treated for with GCs (e.g. Rheumatoid Arthritis). Mechanism based research to study the effects of GCs on atherogenesis, without confounding factors, is lacking. Only few studies were performed on GCs in healthy subjects but none of them explored their effects on foam cell formation [16,17]. Our study thus aims to further our understanding of the role of specific glucocorticoid, prednisone, in the process of atherogenesis. In order to achieve that we plan to study the following: 1. The effects of five days of treatment with prednisone on serum lipid concentration and oxidative stress. 2. an Ex-vivo study is planned where the serum of healthy human subjects treated with Prednisone, will be introduced to J774A.1 murine macrophage-like cell line, a well-studied macrophage foam cell formation model.
The purposes of this study are to determine the safety and tolerability of MK-7162 when administered in combination with pembrolizumab (MK-3475) and to establish a preliminary recommended Phase 2 dose (RP2D) of MK-7162 when administered in combination with pembrolizumab.
The main purpose of the study was to determine the onset of Mavenclad® action by frequent magnetic resonance imaging (MRI) assessment of the combined unique active (CUA) lesions in participants with highly active relapsing multiple sclerosis (MS).
The purpose of this study is to evaluate treatment of advanced Parkinson's Disease (PD) patients on levodopa-carbidopa intestinal gel (LCIG) monotherapy in a routine clinical setting.
The purpose of this study was to evaluate the efficacy and safety of pembrolizumab + epacadostat vs pembrolizumab + placebo in participants with cisplatin-ineligible urothelial carcinoma.
The purpose of this pilot study is to examine the initial efficacy of a multi-dimensional coaching intervention ("Parentship") for parents of adolescents with High Functioning Autism (HFASD). The "Parentship" protocol is a short-term intervention program in occupational therapy that aims to promote parental resilience and enhance adolescents' participation in daily life.
Migraine is a common neurologic with attacks of headache and associated symptoms such as nausea, vomiting, phono and photophobia. Migraine can lead to substantial functional impairment. Recent evidence suggests that electro stimulation is effective in providing relief for chronic headaches including migraine. It is tolerable by patients and associated with no adverse effects. The device utilizes electro stimulation to achieve conditioned pain modulation (CPM). CPM an stimulate endogenous analgesic mechanism. The modulatory effect is over the whole body, and can be induced anywhere. This is a prospective, randomized, double-blind, sham controlled multi-center trial. Ratio between treatment and control groups will be 1:1, stratified by center and use of preventive medications. The study objectives is to demonstrate the safety and effectiveness of the Nerivio Migra electro stimulation device for the reduction of migraine headache during an attack of migraine with or without aura. The study is intended for subject with 2-8 migraine episodes per month. patients will receive the device, either an active or a placebo type, and will be asked to use the device at home or in any location that they will be when the migraine starts. The study hypothesis is that electro stimulation delivered transcutaneously to the peripheral nervous system at onset of a migraine attack significantly reduce headache pain demonstrated by a significant difference between proportions of responders to the active treatment stimulation in comparison to proportion of responders that will use a placebo device.
Diabetes mellitus (or diabetes) is a chronic, metabolic disease characterized by elevated levels of blood glucose. Patients with diabetes need to monitor their blood glucose level several times a day to control their medical state. Modern biosensors have become a promising solution for non-invasive blood glucose measurements. This study aims to validate the efficacy and the accuracy of Glucometry Monitor (NIGM) developed by Spectrophon LTD incorporated in smart watches. Method Participants will use Spectrophon biosensors to non-invasively estimate the level of glucose in blood. Blood will also be collected and the glucose level will be checked with commercially available blood glucose analyzers . All sets of data will be compared to estimate the accuracy of measurements of Spectrophon NIGM
This study is an open-label split-mouth study in which Pocket-X Gel, a periodontal in-situ gelling product, will be applied to periodontal pockets in one/two mouth segment(s) of participants, following scaling and root planing on the entire mouth, while the contralateral segment(s) will serve as control. The aim of the study is to investigate the safety and efficacy of Pocket-X Gel in improving the healing of the gingiva and preventing bacterial re-colonization in the periodontal pocket following scaling and root planing.
