NCT ID: NCT03196583 Recruiting - Clinical trials for Obstructive Sleep Apnea

Efficacy of a Novel MAD in OSA

BVL Project
Start date: May 10, 2017
Phase: N/A
Study type: Interventional

Oral appliances (OA) have emerged as an alternative to continuous positive airway pressure (CPAP) for obstructive sleep apnea (OSA) treatment. The most commonly used OA reduces upper airway collapse by advancing the mandible (mandibular advancement devices, MAD). There is a strong evidence base demonstrating that MADs improve OSA in the majority of patients, including some with more severe disease. However, MADs are not efficacious for all, with approximately one-third of patients experiencing no therapeutic benefit. Patients often prefer MADs to gold-standard CPAP treatment. Head-to-head trials confirm CPAP is superior in reducing OSA parameters on polysomnography; however, this greater efficacy does not necessarily translate into better health outcomes in clinical practice. Comparable effectiveness of MADs and CPAP has been attributed to higher reported nightly use of MADs, suggesting that inferiority in reducing apnoeic events may be counteracted by greater treatment adherence. The MAD in study, called Bite-Velo Linguale (BVL), features a novel monobloc device including a tongue retainer, a suction cavity that maintains the tongue down onto the mouth floor in order to prevent it from raising towards the hard palate, and therefore increasing the retro lingual aerial space. Its design requires the presence of only four occlusal points, allowing for a direct anchorage onto the mandibular bone, thus reducing the risk for occlusal changes, tooth loosening and the development of an anterior cross bite, which represent some of the major long-term adverse effects of oral appliances. MADs are generally well tolerated, although short-term adverse effects during acclimatization are common. Long-term dental changes do occur, but these are for the most part subclinical and do not preclude continued use. The BVL in study features technological advances aimed at preventing long-term dental changes, as well as improving tolerability and easiness of use.

NCT ID: NCT03196089 Recruiting - Clinical trials for Chronic Obstructive Pulmonary Disease

Effect of Short-term Oxygen During CPET in COPD

Start date: June 2, 2017
Phase: Phase 2
Study type: Interventional

In a randomized, sham-controlled trial the investigators will test whether supplemental oxygen given during cardiopulmonary exercise testing will improve exercise performance and physiological parameters in patients with chronic obstructive pulmonary disease.

NCT ID: NCT03195959 Recruiting - Clinical trials for Pulmonary Hypertension

Effect of Normobaric Hypoxia and Hyperoxia in Patients With Pulmonary Hypertension

Start date: June 22, 2017
Phase: N/A
Study type: Observational

Pulmonary Hypertension (PH) is a severe disease with a bad prognosis. However, thanks to extensive research in this field, there are more and better treatment options that allow patients to participate in recreational activities at moderate altitude or bring up the question of air-travel. Still very few is known about the effects hypoxic conditions have on PH patients. The aim of this study is to investigate the effects of hypoxia in comparison to normoxia and hyperoxia on pulmonary hemodynamics in patients with pulmonary hypertension during routine right heart catheterisation. We aim to get insight into the pathophysiology of pulmonary hemodynamics under hypoxic conditions in comparison to normoxia and hyperoxia in patients with pulmonary arterial and chronic thromboembolic pulmonary hypertension compared with control patients, that are scheduled for right heart catheterisation due to dyspnea but have no PH.

NCT ID: NCT03195062 Recruiting - Test Meal Clinical Trials

Fructose Extra-splanchnic Metabolism and Its Effects on Systemic Flux of Substrates (FruPP)

Start date: March 23, 2017
Phase: N/A
Study type: Interventional

In parallel to the dramatic rise in metabolic diseases and diabetes observed over the past fifty years, the generalization of added sugar in processed food led to a marked increase in fructose consumption in almost all countries, and epidemiological studies demonstrated that the consumption of sugar-sweetened beverage (containing at least 50% of fructose) is associated with the development of diabetes, hepatic steatosis, dyslipidemia and obesity. The objective of the study is to measure the amount of fructose that escape first-pass hepatic extraction after oral ingestion (fructose+glucose), and gain insights into its metabolic fates with the use of tracers.

NCT ID: NCT03192969 Not yet recruiting - Clinical trials for Giant Cell Arteritis

A Study to Evaluate Efficacy and Safety of Subcutaneous Abatacept With Steroid Treatment Compared to Steroid Treatment Alone in Adults With Giant Cell Arteritis (GCA)

Start date: July 15, 2017
Phase: Phase 3
Study type: Interventional

To investigate the safety and efficacy of abatacept with steroid treatment in comparison to steroid treatment alone in up to a 28 week taper of steroid treatment to sustain remission of Giant Cell Arteritis in adults.

NCT ID: NCT03192332 Not yet recruiting - Ischemic Stroke Clinical Trials

Bridging Thrombolysis Versus Direct Mechanical Thrombectomy in Acute Ischemic Stroke

Start date: August 31, 2017
Phase: N/A
Study type: Interventional

Intravenous thrombolysis with recombinant tissue-type plasminogen activator (IV t-PA) has been the only proven therapy for acute ischemic stroke (AIS) for almost 20 years. Whether IV t-PA prior to endovascular clot retrieval is beneficial for AIS patients with a proximal vessel occlusion in the anterior circulation has currently become a matter of debate and is a relevant unanswered question in clinical practice. The main objective is to determine whether subjects experiencing an AIS due to large intracranial vessel occlusion in the anterior circulation will have non-inferior functional outcome at 90 days when treated with direct mechanical thrombectomy (MT) compared to subjects treated with combined IV t-PA and MT. The secondary objectives are to study causes of mortality, dependency and quality of life in these AIS patients.

NCT ID: NCT03191799 Not yet recruiting - Hemophilia A Clinical Trials

A Study to Evaluate the Safety and Tolerability of Prophylactic Emicizumab in Hemophilia A Patients With Inhibitors

Start date: July 27, 2017
Phase: Phase 3
Study type: Interventional

This is a phase IIIb, single arm, open-label, multi-center study to evaluate the safety and tolerability of emicizumab in participants with congenital hemophilia A who have documented inhibitors against Factor VIII (FVIII) at enrollment. Approximately 200 participants, aged 12 or older, will be enrolled in this study and are expected to be enrolled at approximately 85 sites globally. Participants will receive an initial weekly dose of prophylactic emicizumab subcutaneously for 4 weeks, followed by a weekly maintenance dose subcutaneously for the remainder of the 2-year treatment period.

NCT ID: NCT03191786 Not yet recruiting - Clinical trials for Non-Small Cell Lung Cancer

A Study of Atezolizumab Compared With Chemotherapy in Treatment Naïve Participants With Locally Advanced or Recurrent or Metastatic Non-Small Cell Lung Cancer Who Are Deemed Unsuitable For Platinum-Containing Therapy

Start date: September 1, 2017
Phase: Phase 3
Study type: Interventional

This Phase III, global, multicenter, open-label, randomized, controlled study will evaluate the efficacy and safety of atezolizumab (an anti-programmed death-ligand 1 [anti-PD-L1] antibody) compared with a single agent chemotherapy regimen by investigator choice (vinorelbine or gemcitabine) in treatment-naïve participants with locally advanced or metastatic non-small cell lung cancer (NSCLC) who are deemed unsuitable for platinum-containing therapy due to poor performance status (Eastern Cooperative Oncology Group [ECOG] performance status of 2-3).
