NCT06702462
The purpose of the study is to assess the propellants,1 - Difluoroethane \[HFA-152a\] (Test) and 1,1,1,2-Tetrafluoroethane \[HFA-134a\] (Reference) for their potential to cause the airways to tighten when delivered through pressurized metered dose inhalers (pMDI). The rationale for this study is to develop a low carbon footprint alternative propellant, HFA-152a, which will have a lower impact on global warming.
NCT05842967
The purpose of this study is to learn about the safety and immunogenicity of a study vaccine (called RSVpreF) in several adult groups. Respiratory Syncytial Virus (RSV) is a common type of virus (germ) that can cause severe illness, where medical help is needed. RSV can lead to airway diseases in all ages. Vaccines help your body make antibodies which help fight against diseases. This is called an immune response. This study will measure how much antibody participants make after receiving RSVpreF (immunogenicity). The study consists of 2 groups (Substudy A and Substudy B). Substudy A is seeking approximately 675 participants who are: * Between 18 and 60 years of age. * Considered having a high likelihood of severe RSV disease due to certain long-term medical conditions. Such medical conditions do not include immunocompromising conditions. Participants will need to come to the study clinic at least 2 times. At the first clinic visit, participants will receive 1 shot of RSVpreF or placebo in the arm by chance. A placebo looks like the study vaccine but contains no active ingredients. At each clinic visit, a blood sample will be taken. A third (final) visit can be either completed in clinic or via telephone contact. This study is about 6 months long for each participant. Substudy B is seeking approximately 200 participants who are: * At least 18 years of age. About half of the participants will be at least 60 years of age. * Considered having a weakened immune system (immunocompromised). Participants will need to come to the study clinic at least 3 times. All participants will receive a shot of RSVpreF at the first study clinic visit. The second study clinic visit will be 1 month later. All participants will receive a second shot of the study vaccine at this second study clinic visit. Blood samples will be taken at the 3 study clinic visits. A fourth (final) visit can be either completed in clinic or via telephone contact. This study is about 7 months long for each participant.
NCT05639894
Brief Summary of Stage 1: The purpose Stage 1 (Phase I/IIa) is to assess the safety and immunogenicity of a single intramuscular (IM) injection of 3 dose-levels of an Respiratory Syncytial Virus (RSV) vaccine candidate formulated with 2 different lipid nanoparticles (LNPs) in healthy adult participants aged between 18 to 50 years, and 60 years and older. The primary objectives of this stage are to assess the safety and immunogenicity profiles across the dose-level groups (low, medium, and high doses) with 2 LNPs. This stage will evaluate the safety and immunogenicity of a booster vaccination administered 12 months after the primary vaccination in a subset of the study population. Brief Summary of Stage 2: The study also also incorporates a Stage 2 (Phase IIa, dose-ranging design) that includes adults aged 60 years and older to assess the safety and immunogenicity of different doses of RSV vaccine encapsulated in one of the LNPs. In the Phase IIa dose-ranging stage, eligible participants will be randomly assigned in a 1:1:1 ratio to receive a single IM administration of RSV vaccine candidate doses, or placebo. Multiple safety analyses will be performed, minimally at D07 and D28. Additional analyses may be performed as data are available.

NCT06746259
The goal of this observational study is to learn about the performance and ease of use of FebriDx when operated by persons without laboratory experience or training in patients with acute respiratory symptoms. The main question it aims to answer is: • Is FebriDx accurate at differentiating bacterial from non-bacterial respiratory infections when used by untrained operators? Trained and untrained participants will run the FebriDx test on patients with respiratory symptoms to evaluate comparability.
NCT07052942
While asthma therapy is becoming more individualized based on asthma phenotypes, more research is needed to tailor newer therapies to individuals. Inhaled corticosteroid (ICS) medications are the foundation of care for all individuals with persistent asthma. But ICS use is not without possible long term side effects. This study will compare two currently available approaches to reduce AEX in primary care patients: (1) use of inhaled corticosteroids (ICS) as part of rescue therapy, also known as MART (Maintenance And Reliever Therapy) or PARTICS (Patient Activated Reliever Trigger Inhaled Corticosteriods) therapy - either of these therapies will be called Rescue-Inhaled Corticosteroids or R-ICS pronounced "Ricks," and (2) use of azithromycin (AZ) as a preventive therapy. These treatments will be studied both individually and in combination.

NCT01148550
The specific aims of this study are (1) to determine the clinical phenotypes and natural history of hepatic RC and FAO disorders, (2) to determine the correlation between genotype and phenotype, (3) to determine if circulating biomarkers reflect diagnosis and predict liver disease progression and survival with the native liver, (4) to determine the clinical outcome of these disorders following liver transplantation, and (5) to develop a repository of serum, plasma, urine, tissue and DNA specimens that will be used in ancillary studies. To accomplish these aims, the ChiLDReN investigators at clinical sites (currently 9 sites) will prospectively collect defined data and specimens in a uniform fashion at fixed intervals in a relatively large number of subjects. Clinical information collected from subjects and their parents will enhance the potential for meaningful research in these disorders. A biobank of previously collected subject specimens and DNA samples will be established for use in ancillary studies to be performed in addition to this study.

Primary Objective To determine if pre-transplant screening for respiratory viral load predicts RVI within 1- year post-transplant among survivors. Secondary Objectives: * To develop and validate a classifier based on pre-transplant immunological profile predictive of developing an acute respiratory viral infection (aRVI), with RSV/PIV3/HMPV/SARS-CoV-2 through one-year post-transplant among survivors. * To develop and validate a classifier based on Day +100 post-transplant immunological profiles predictive of developing an acute respiratory viral infection (aRVI),with RSV/PIV3/HMPV/SARS-CoV-2 through one-year post-transplant among survivors .
NCT06066502
The goal of this interventional study is to compare standard mechanical ventilation to a lung-stress oriented ventilation strategy in patients with Acute Respiratory Distress Syndrome (ARDS). Participants will be ventilated according to one of two different strategies. The main question the study hopes to answer is whether the personalized ventilation strategy helps improve survival.
NCT04402957
To evaluate the proportion of subjects alive and free of respiratory failure (e.g. need for non-invasive or invasive mechanical ventilation, high flow oxygen, or ECMO) and free of the need for continued renal replacement therapy (RRT) on Day 28. The need for continued RRT at Day 28 will be defined as either dialysis in the past 3 days (Day 26, 27, or 28) or an eGFR on Day 28 \<10 mL/min/1.73 m2.
NCT04193878

NCT06102330
This is a multicenter study to test a decision-making support process for families and clinicians facing decisions about chronic home ventilation for a child. The investigators hypothesize that the intervention will increase family preparedness for decision-making and will improve clinician-family shared-decision making. Half of families will be assigned to "usual care" arm and half to the "intervention" arm. Intervention families will view the study website with study staff and will answer questions related to website content. All families will be interviewed and surveyed at 1, 6 and 12 months after enrollment. Each family will designate 1-2 physician involved in the decision about home ventilation; each physician will be interviewed and surveyed at 1 month.
