A Study to Evaluate SHR-1210 in Patients With Advanced or Metastatic NSCLC

Lung NeoplasmsCarcinoma8 more

This is an open-label, single-arm, multi-center, phase 2 Study to evaluate SHR-1210(anti-PD-1 antibody) in in adult Chinese patients with advanced or metastatic non-small cell lung cancer who failed or progressed to prior first-line systemic treatment. Enrolled subjects will be assigned to 4 cohorts on the basis of PD-L1 expression in tumor cells(<1%, ≥1%-25%, ≥25%-50%, ≥50%) all will be treated with the standard SHR-1210 dose (200mg) , Q2W, until documented progressive disease (PD) occurs. Subjects will return to the clinic once every two weeks. Radiographic disease assessments will be performed every 6 weeks. The primary study hypothesis is that treatment with SHR-1210 improves Objective Response Rate when compare with standard second-line therapy, no matter how much PD-L1 expression in tumor.

Use of Hyperpolarized Xenon Gas for Lung Imaging in Children and Adults

Respiratory Disorders

The goal of this study is to evaluate the usefulness of hyperpolarized (HP) 129Xe (xenon) gas MRI for regional assessment of lung function in a normal population of children and adults and in adults and also in children with respiratory compromise due to a variety of diseases.

Validation of a Walk-Time Limit Test (WTLT) Derived From the 6-Minute Walk Test (6-MWT) in Patients...

Chronic Obstructive Pulmonary DiseaseCardiovascular Insufficiency

Many exercise tests are commonly used to evaluate the changes of exercise tolerance following rehabilitation programs in patients with chronic respiratory diseases. Among the tests (6-MWT, incremental test, ...), the literature seems to indicate that endurance time is the most responsive parameter for detecting and quantifying changes in exercise capacity following a rehabilitation program. Although its clinical interest is undeniable, the endurance shuttle walking test is rarely used because it requires the prior performance of two incremental shuttle walking tests to determine the walking speed imposed on the patient. In this protocol, we propose to test a Walk-Time Limit Test (WTLT) derived from the 6-minute walk test (6-MWT) and based on the average walking speed achieved in this test commonly used in the follow-up of patients with chronic diseases. TTLM validation would improve the functional assessment of patients with chronic diseases while limiting the number of exercise tests.

Real-time Effort Driven VENTilator Management

Ventilation Therapy; ComplicationsDiaphragm Disease1 more

This study is a Phase II controlled clinical trial that will obtain comprehensive, serial assessments of respiratory muscle strength and architecture to understand the evolution of ventilator-induced respiratory muscle weakness in critically ill children, and test whether a novel computer-based approach (Real-time Effort Driven ventilator management (REDvent)) can preserve respiratory muscle strength and reduce time on MV. REDvent offers systematic recommendations to reduce controlled ventilation during the acute phase of MV, and uses real-time measures from esophageal manometry to adjust supported ventilator pressures such that patient effort of breathing remains in a normal range during the ventilator weaning phase. This phase II clinical trial is expected to enroll 276 children with pulmonary parenchymal disease, anticipated to be ventilated > 48 hrs. Patients will be randomized to REDvent-acute vs. usual care for the acute phase of MV (interval from intubation to first spontaneous breathing trial (SBT)). Patients in either group who fail their first Spontaneous Breathing Trial (SBT), will also be randomized to REDvent-weaning vs. usual care for the weaning phase of MV (interval from first SBT to passing SBT). The primary clinical outcome is length of weaning (time from first SBT until successful passage of an SBT or extubation (whichever comes first)). Mechanistic outcomes surround multi-modal serial measures of respiratory muscle capacity (PiMax), load (resistance, compliance), effort (esophageal manometry), and architecture (ultrasound) throughout the course of MV. Upon completion, this study will provide important information on the pathogenesis and timing of respiratory muscle weakness during MV in children and whether this weakness can be mitigated by promoting more normal patient effort during MV via the use of REDvent. This will form the basis for a larger, Phase III multi-center study, powered for key clinical outcomes such as 28-day Ventilator Free Days.

Advanced Point-of-care Technology During In-home Assessment Among Older Adults

Acute Respiratory DiseaseAcute Illness

Due to ageing-related physiological changes, diagnosing older adults is challenging. Delayed disease recognition lead to adverse health outcomes and increased hospitalisation, which is why there is a need to develop new procedures for timely diagnosis and treatment of older adults. Point-of-care technology, e.g. focused lung ultrasound scan and bedside analysis of blood samples (leucocytes with differential count, electrolytes and creatinine) carried out in the patients' home may support clinical decision-making, and potentially reduce acute hospital admissions. The trial's overall aim is to investigate whether increased point-of-care technology, i.e. focused lung ultrasound scan and bedside blood analysis, used as in-home diagnostics in older adults with acute respiratory symptoms, can qualify the general practitioner's clinical decision-making for early treatment initiation and eventually reduce acute hospital admission.

Screening for Cancer in Patients With Unprovoked VTE

Venous Thromboembolic DiseaseRespiratory Disease5 more

Open and multicenter randomized clinical trial (1:1) comparing limited screening with extended screening with the performance of Positron emission tomography-computed tomography (PET-CT) scan in the search for neoplasms in patients with unprovoked venous thromboembolic disease at high risk of developing cancer at follow-up. Introduction: Cancer screening in patients with unprovoked venous thromboembolic disease (VTE) is controversial. In the last years, a score has been developed that selects patients at high risk of developing cancer during follow-up. Objective: To estimate the impact of an active cancer search strategy using 18-fluordesoxiglucose (FDG) PET-CT in unprovoked VTE with high-risk to develop cancer. Specific Objectives: 1) Number of neoplasms diagnosed in the screening process: 2) number of neoplasms diagnosed at an early stage, 3) impact on survival of the strategy; and 4) impact on the quality of life. Cancer will be considered from 30 days up to 12 months after the diagnosis of VTE. Scope: 20 Spanish hospitals. Design: Open-label, multicentre Randomized clinical trial (1: 1) comparing the performance of PET-CT versus limited screening for cancer. Population: Patients older than 18 years with unprovoked VTE at high risk of presenting cancer at follow-up (≥3 points in the score of Jara-Palomares et al., Chest 2017). Follow-up: 12 months after VTE. Sample: The sample size calculated is 650 patients, to obtain a power of 80%, with a level of significance of 5%, and taking into account a 10% loss of follow-up.
