NCT02995733
Asthma imposes a significant burden in the US in terms of morbidity, costs to society, individual suffering, loss of productivity and mortality. African Americans (AA) and Hispanic/Latinos (H/L) bear a disproportionate share of that morbidity. Despite national guidelines for asthma treatment, the gap between these groups and whites has been stable or widening. The need for pragmatic research to address the continuing burden is widely recognized. Patients use asthma reliever inhalers to provide immediate relief of symptoms. Controller inhalers (inhaled corticosteroids (ICS)) are intended to be used regularly to prevent symptoms and attacks. Guidelines suggest that they be used daily, on a fixed basis, in all but the mildest asthma. However, adherence by patients and implementation of evidence-based guideline recommendations by clinicians has been poor. Gap analysis suggests that it is difficult to improve adherence to the current recommendations without complex and resource-intensive interventions. Studies have examined symptom-activated use of ICS triggered by use of a reliever medication. The Investigators call this approach PARTICS - Patient Activated Reliever-Triggered Inhaled CorticoSteroid. Explanatory, non-real world studies suggest that PARTICS can produce up to 50% reductions in asthma attacks compared with usual care, while reducing ICS use by half or more. These studies have been performed in pre-selected populations, which represent less than 5% of asthma patients. The previous studies have been done with repeated education and adherence checks in both the intervention and control arms. The investigators have consulted with AA and H/L patients, health care providers, leaders of professional societies, advocacy groups, health policy leaders, pharmacists, and pharmaceutical manufacturers. All groups have indicated that asthma decision making would be changed if we demonstrated that implementing PARTICS improves important asthma outcomes such as reducing exacerbations. The Investigators have designed a study with the stakeholders to determine whether PARTICS can improve outcomes that are important to patients when superimposed on a background provider-educated standard of care through the Asthma IQ system. The Investigators propose a study entitled PREPARE: Patient Empowered Strategy to Reduce Asthma Morbidity in Highly Impacted Populations. The Investigators aim to determine whether PARTICS can reduce asthma morbidity in AA and H/L.
NCT02918019
This is a Phase IIb, randomized, placebo-controlled, double-blind, multicenter, multi-arm study which will evaluate efficacy, safety, and pharmacokinetic of MSTT1041A compared with placebo as add-on therapy in participants with severe, uncontrolled asthma who are receiving medium- or high-dose inhaled corticosteroid (ICS) therapy and at least one of the following additional controller medications: long-acting beta-agonists (LABA), leukotriene modifier (LTM), long-acting muscarinic antagonist (LAMA), or long-acting theophylline preparation. The total duration of this study for each participant is approximately 70 weeks including screening, run-in, treatment, and follow-up.
NCT05258617
An informational evaluation of COVID-19 patients who receive low-level laser therapy in addition to a normal regimen of treatment for symptoms associate with COVID-19. Results are compared to statistical observations published in literature from patients receiving standard care for COVID-19 symptoms without low-level laser therapy.
NCT04006964
The diagnosis of a lung function anomaly requires the evaluation of pulmonary function by spirometry. However, some patients (e.g. children, elderly, or diseased individuals) may have difficulty performing the related forced maximal respiratory maneuver correctly. Forced Oscillation Technique (FOT) measures lung impedance during tidal breathing, requiring minimal patient cooperation. The purpose of this study is to establish the diagnostic accuracy of FOT parameters alone or in combination with lung volumes in detecting lung function anomalies as compared with spirometry and with the diagnosis made by the physician.
NCT04533685
This trial is taking place in Los Angeles, CA among patients from primary care practices within the UCLA Health System. The study design is a 2x2x2 factorial design, nested in a parallel 2-arm trial. The parallel arms are control v. reminder letter (reminder messages sent via the patient portal, reminding participants of an overdue influenza vaccine) Nested within the reminder letter arm, we will have 3 additional components: * A direct scheduling link within the reminder letter enabling the patient to schedule an influenza vaccine only visit (direct scheduling link vs. no direct scheduling link). * A pre-commitment prompt (pre-commitment prompt vs. no prompt) asking about a patient's intention to get the influenza vaccination * A pre-appointment reminder, encouraging patients to ask for their influenza vaccine at their upcoming appointment (pre-appointment reminder encouraging influenza vaccination vs. standard pre-appointment reminder not mentioning influenza vaccination)
NCT05228717
This study seeks to define the ultrasound profile of patients with COVID-19, and document the progression of these ultrasound findings to develop prognostication and clinical decision instruments that can help guide management of patient with COVID-19. Primary aims include the development of ARDS, refractory hypoxemia, acute cardiac injury, pulmonary embolism, pneumothorax or death. Secondary aims include potential change in CT and plain film utilization given the use of POCUS, as well as emergency department and inpatient LOS (length of stay).
NCT03227029
The purpose of this study was to evaluate the infectivity, safety, and immunogenicity of the recombinant live-attenuated respiratory syncytial virus (RSV) vaccines RSV ΔNS2/Δ1313/I1314L or RSV 276 when delivered as nose drops to RSV-seronegative infants 6 to 24 months of age. This study was a companion study to Center for Immunization Research (CIR) 321.
NCT04452565

NCT02139644
The primary objective of this study was to evaluate the efficacy of fluticasone propionate multidose dry powder inhaler (Fp MDPI) and fluticasone propionate/salmeterol xinafoate multidose dry powder inhaler (FS MDPI) when administered over 12 weeks in patients 12 years of age and older with persistent asthma. Study drug and placebo was supplied in Teva multidose dry powder inhaler (MDPI) devices and provided for participants to use at home. Participants performed spirometry at every visit. Each participant was given a diary at each visit for use until the next visit. Rescue medication (albuterol/salbutamol) was dispensed at each visit, if needed, as determined by the investigational center personnel.
NCT00094016
The primary objective of this study is to compare the QVAR-Easi-Breathe 100 mcg/day and QVAR-Easi-Breathe 200 mcg/day with placebo relative to changes in forced expiratory volume in 1 second (FEV1) results following 12 weeks of treatment. Secondary objectives such as daily asthma symptoms scores (per week), morning peak expiratory flow (PEF) values, nocturnal awakening and utilization of rescue medication per day also will be evaluated. In addition, an exploratory evaluation will assess the comparability of the two devices (i.e., QVAR-Easi-Breathe versus QVAR-MDI) at the same dose levels.
NCT04195958
This study will assess the effect of omalizumab on exercise capacity, physical activity, and sleep quality after 24 weeks of treatment in participants with moderate to severe allergic asthma. Exercise capacity will be assessed using cardiopulmonary exercise testing (CPET). Physical activity and sleep quality will be assessed with a wearable physical activity and sleep monitor. The study will consist of a 4-week screening period, a 24-week treatment period, and a 4-week safety follow-up. Approximately 60 participants will be enrolled, and omalizumab will be dosed according to the approved United States Package Insert (USPI) dosing table.
NCT04360096
Brief Summary: SARS-CoV-2 virus infection is known to cause Lung Injury that begins as dyspnea and exercise intolerance, but may rapidly progress to Critical COVID-19 with Respiratory Failure and the need for noninvasive or mechanical ventilation. Mortality rates as high as 80% have been reported among those who require mechanical ventilation, despite best available intensive care. Patients with severe COVID-19 by FDA definition who have not developed respiratory failure be treated with nebulized ZYESAMI™ (aviptadil acetate, a synthetic version of Vasoactive Intestinal Polypeptide (VIP)) 100 μg 3x daily plus Standard of Care vs. placebo + Standard of Care using an FDA 501(k) cleared mesh nebulizer. The primary outcome will be progression in severity of COVID-19 (i.e. critical OR severe progressing to critical) over 28 days. Secondary outcomes will include blood oxygenation as measured by pulse oximetry, dyspnea, exercise tolerance, and levels of TNFα IL-6 and other cytokines.
