9 Clinical Trials for Various Conditions
Phase 3 within-subject non-inferiority trial of Technegas ventilation imaging compared to Xenon-133 (Xe-133) ventilation imaging to demonstrate the non-inferiority of Technegas compared to Xe-133 ventilation studies with respect to subject pulmonary ventilatory distribution. Subjects will undergo site-specific standard of care (SOC) Xe-133 imaging per medical needs followed by Technegas ventilation imaging per study protocol.
Bedside ultrasonography for detection of pneumothorax after transbronchial lung biopsies in lung transplant patients
This study is part of the development and validation of a non-invasive lung screening test which aim to identify early stage lung cancer in patients at high risk for lung cancer.
The researchers plan to investigate two ways of visualizing and planning to account for the respiratory motion which takes place while treating lung tumors with radiation therapy. The researchers will determine if a traditional snapshot (free-breathing) CT or a longer-lasting CT encompassing the breathing cycle better matches a patient's breathing during treatment.
Expiratory Flow Limitation (EFL) occurs when the airways become compressed, which usually results when the pressure outside the airway exceeds the pressure inside the airway. EFL can be detected using the Forced Oscillation Technique (FOT), which has been incorporated into a new screening feature in the Philips Respironics BiPAP Ventilator overall platform (Vector Non-Invasive (NIV) device). In this study, the Vector device will be used in a cross-sectional non-randomized epidemiology study to assess the prevalence and severity of expiratory flow limitation in a community COPD population. The study will also investigate how the presence of EFL may correlate with other physiological biomarker endpoints in the COPD patient. Participants will include 100 male and females with a diagnosis of COPD between the ages of 40 and 80. During the one-visit study, participants will undergo an EFL screening using the Vector device. If EFL is not detected during the screening after 5 minutes, the participant will not continue. If EFL is detected by the device, the participant will continue to wear it while it measures the level of therapy that is needed to eliminate EFL. Twenty minutes of pressure therapy will then be provided and the final Expiratory Positive Airway Pressure (EPAP) that is determined to abolish the participants EFL will be recorded. Participant characteristics (e.g. health history, behaviors, anthropometric, vitals, etc.) will be also be collected via questionnaires, medical record review, and physical exam. Future benefits of the study will be to gain a better understanding of the Vector screening feature and the characteristics of patients who present with varying degrees of EFL severity.
This is a multi-center, open-label, non-randomized Phase I study to define the safety profile, maximum tolerated dose (MTD) and potential pharmacokinetic interaction of regorafenib in combination with pemetrexed and cisplatin in patients with Stage IIIB or Stage IV nonsquamous Non-Small Cell Lung Cancer (NSCLC) and to determine the impact of the combined administration on the pharmacokinetics of regorafenib, pemetrexed, and cisplatin. In Part A of this trial, regorafenib will be administered in a sequential dosing with a seven day wash out period before the next infusion of pemetrexed and cisplatin. Regorafenib will be administered at a dose of 160 mg qd from Day 2 to Day 14 followed by a 7 days break. In Part B of this trial, regorafenib will be administered continuously from Day 1 to Day 21. Only in Cycle 1, regorafenib dosing will start on Day 2 in order to assess the pharmacokinetics of pemetrexed and cisplatin without concomitant regorafenib dosing.
This study is intended to be an evaluation of the properties of human sputum collected from patients with COPD. It is hypothesized that cationic airway lining modulators will have beneficial effects on the rheological properties of sputum derived from patients with COPD. Approximately 10 patients with COPD will collect sputum at home for 5 days. Samples will be collected and tested in laboratory tests.
The purpose of this study is to determine the safety and maximum tolerated dose of inhaled NX1011 for the treatment of pulmonary arterial hypertension (PAH).
Patients who are at least 18 years of age and have a type of cancer known as advanced non-small cell lung cancer may be eligible for this study if they meet all of the inclusion/exclusion criteria. Background: The standard treatment for patients with advanced non-small cell cancer is chemotherapy. The two drug combination, carboplatin (Paraplatin) and paclitaxel (Taxol), is commonly used as the first treatment. Unfortunately, standard treatment with chemotherapy only shrinks the cancer in about 30% of patients that receive it. There is no way to predict who will or won't benefit from this treatment. The researchers at the University of Michigan would like to determine if the genes of the lung cancers in patients enrolled in this study will help predict whether or not the tumors shrink when exposed to standard chemotherapy. The goal is to find a set of lung cancer genes that will predict successful treatment with carboplatin and paclitaxel in patients with non-small cell lung cancer. The actual treatment, carboplatin and paclitaxel, involved in this study is not experimental. The experimental aspect of this study is the identification of predictors of response to treatment. To do this, it would require a sample of your cancer. If your initial surgery or biopsy was done at the University of Michigan, we may already have an adequate sample of your cancer that could be used for this research. In that case, we are asking for your permission to use this sample for this study. However, if you meet all eligibility criteria and agree to participate in this research study and an adequate sample is not available, you will need to undergo another biopsy procedure for us to obtain a sample of your cancer. Obtaining a tumor sample is the most crucial part of this research study.
