92 Clinical Trials for Various Conditions
This is a Phase 2, randomized, multicenter study in adult and adolescent participants with asthma and type 2 inflammation
This study aims to identify whether early administration of magnesium sulfate in moderate asthma exacerbations can potentially avoid admission, decrease length of stay in the emergency department (ED), decrease length of stay (LOS) in the general hospital floor vs pediatric intensive care unit (PICU), and decrease the need for respiratory support.
The primary objective of the study is to assess the efficacy of high dose and low dose fluticasone propionate (Fp)/albuterol sulfate (ABS) integrated electronic module multidose dry powder inhaler (eMDPI) compared to ABS eMDPI in decreasing severe clinical asthma exacerbation (CAEs). Secondary Objectives: To evaluate the efficacy of Fp/ABS compared to ABS and the effect on systemic corticosteroid (SCS) exposure To evaluate the safety and tolerability of Fp/A BS The duration for each participant will be a minimum of 28 weeks including 2 weeks of screening, 2-4 weeks of run-in period and a double blind treatment period of minimum 24 weeks, however due to the event-driven nature of this study, the duration may range up to approximately 35 months depending on the timing when the participant was enrolled to the study, and when the study reaches its completion criteria.
A study to evaluate the efficacy and safety of benralizumab administered subcutaneously in patients ≥ 6 to \< 18 years of age with severe eosinophilic asthma, including a well-documented history of asthma exacerbations and uncontrolled asthma receiving high-dose inhaled corticosteroid (ICS) plus at least one additional controller medication.
This is a multi-center, double-blind, placebo-controlled, randomized trial of dupilumab adjunctive therapy for prevention of asthma exacerbations in urban children and adolescents with T2-high exacerbation-prone asthma.
To identify asthma-related physiological changes observed by wearable devices in real-world conditions by monitor multiple sensing modalities (e.g., heart rate (HR), heart rate variability (HRV), activity level, spirometry, coughing sounds) in order to find reliable signatures of impending asthma exacerbation and systematically explore any challenges on the use of wearable technologies.
To study the change from baseline in IL-1β (interleukin 1 beta) concentrations in the nasal airway during acute asthma exacerbation, specifically to measure the degree of change and identify the timing of peak IL-1β concentration. This information will allow the investigators to estimate effect size and guide decisions about the optimal timing of anakinra administration for the future study.
The investigators will study the use of a home-based spirometer (Spirobank Smart spirometer) that connects to a smartphone app (VitalFlo) in teenagers with persistent asthma to determine if clinically significant changes in lung function detected by the spirometer are associated with patient-reported asthma symptoms.
Patients presenting to the emergency department with acute asthma exacerbation will be assigned to peak-expiratory flow rate (PEFR) guided management and non-PEFR guided management.
The purpose of this study is to see if treatment with a medication called Nucala® (mepolizumab), given along with standard asthma care, makes children less likely to have asthma attacks.
Objective: To determine the extent to which high-dose (30mg) oral montelukast, added to standard treatment in children with moderate and severe acute exacerbations improves outcomes. Central Hypothesis: High-dose oral montelukast, added to standard treatment in children aged 5 to 17 years with moderate and severe acute asthma exacerbations, rapidly improves lung function, clinical severity, hospitalization rate and 72-hour symptom burden. Secondary Hypotheses: 1. There are greater effects of high-dose oral montelukast on lung function and on the secondary outcomes in the presence of respiratory viral detection or leukotriene-mediated inflammation; and 2. There is an interaction between viral detection and urinary leukotriene 4 level with treatment-response. Design: A two-arm, parallel randomized controlled trial of high-dose oral montelukast versus identical placebo, as add-on to standard treatment, in children aged 5 to 17 years with moderate and severe acute asthma exacerbations. Intervention: High-dose oral montelukast added to standard treatment in comparison with standard treatment as the 2nd treatment-allocation arm. Primary and Important Secondary Endpoints: For the Primary Aim, the primary outcome measure to be compared between arms will be change of %-predicted airway resistance by impulse oscillometry (IOS) at 5Hz (%R5) at 2 hours after treatment initiation. Secondary outcomes will include improvement of %-predicted FEV1 (%FEV1), clinical severity measured using the validated Acute Asthma Intensity Research Score (AAIRS), hospitalization rate, and 72 hour symptom burden using the Pediatric Asthma Caregiver Diary (PACD). For the Secondary Aim, the investigators will determine (1) The effects of high-dose oral montelukast on lung function and on our secondary outcomes in the presence of nasal viruses and of greater leukotriene-mediated inflammation; and (2) The degree of interaction between viral detection and urinary leukotriene E4 (LTE4) level with treatment-response. Laboratory evaluations: The primary outcome (change of %R5) and select secondary outcomes (%FEV1, AAIRS, LTE4) will be measured before and again at 2 hours after treatment initiation. The other secondary outcomes will be measured at the time of hospitalization decision-making by the clinical team (hospitalization rate) or at 72-hours after treatment initiation (PACD).
Study Summary: Title: A Randomized Controlled Trial of Noninvasive Positive Airway Pressure in the Pediatric Emergency Department for the Treatment of Acute Asthma Exacerbations Principal Investigator: Thomas J. Abramo, MD Hypothesis: For acute moderate to severe pediatric asthma exacerbations the use of NIPPV/BiPAP, in conjunction with current standard of care therapies, will lead to a more rapid improvement in patient ventilation, faster resolution of respiratory distress and result in improved ventilatory parameters, secondary outcomes and pediatric asthma scores. Study Design: Prospective, randomized controlled trial Study Duration: This study will be conducted over a 36 month period. Sample Size: 240 subjects Population: Children ages 2-17 years of age presenting to the ED with Acute asthma exacerbation and a Pediatric Asthma Score (PAS) ≥ 8. Synopsis: Eligible subjects will be randomized to either a control group or study groups. The study groups will be either a NIPPV/BiPAP group. The subjects in the study groups will continue to receive all standard of care therapies per the asthma severity protocols. All nebulized therapies will be given through the NIPPV circuit. Patients will be assessed by the pediatric asthma score (PAS), measured respiratory parameters, volumetric end tidal carbon dioxide monitoring and measured cardiac parameters. Objectives: A. Evaluate if the use of NIPPV/BiPAP in conjunction with traditional inhaled beta-agonists improves the outcome in pediatric patients with acute moderate to severe asthma in the acute setting. B. Describe the physiology of NIPPV/BiPAP by measuring cardiac parameters in children randomized to a NIPPV group. C. Monitor safety of NIPPV/BiPAP use for acute asthma exacerbations in children. Safety A.: The study must be IRB approved. B.: Appropriate consent and assent documents will be obtained prior to enrolling the subject in the study. C.: A clear safety plan including DSMB will be established to monitor for adverse events. D.: Confidentiality will be ensured for all subjects enrolled in the study.
Comparing one versus two doses of oral dexamethasone for the treatment of asthma in the pediatric emergency department.
This study will determine whether vitamin D3 prevents severe asthma attacks in children who have a serum vitamin D (25(OH)D) level \<30 ng/ml and who are being treated with inhaled corticosteroids for asthma. Half the participants will receive vitamin D3 at a dose of 4,000 IU/day, and the other half will receive placebo.
Asthma is a growing problem, especially in children. It causes frequent wheezing, shortness of breath, chest tightness, and cough. A cold that is caused by a virus (viral cold) can sometimes make asthma symptoms worse. This study will help investigators learn about the way colds are related to asthma attacks among children who need higher amounts of medications to control their asthma. Investigators want to learn why viral colds sometimes cause asthma attacks and other times do not by studying the immune system response in samples taken from the nose and blood.
The objective of this randomized control trial is to investigate the efficacy of an adjunct positive airway pressure (PAP) nebulizer device known as "AccuPAP" in the treatment of moderate-severity acute asthma exacerbations in children ages 6 - 17 years in comparison with an institutional standard continuous dual-therapy nebulizer treatment. The investigators main goal, more specifically, is to determine if the additional positive airway pressure provided by the AccuPAP device when used in treating children with moderate-severity asthma exacerbations provides a more optimal delivery of bronchodilator therapy when compared to institutional standard protocol nebulizer delivery mask which does not employ the use of positive airway pressure in medication delivery. The investigators have determined that the change in a study-validated Acute Asthma Intensity Research Score (AAIRS) which will be considered statistically significant for a patient is 2 points or greater after the first treatment has been completed.
The purpose of this study is to compare the efficacy of a single dose of dexamethasone vs. two doses of dexamethasone in mild and moderate asthma exacerbations pediatric patients.
This study of vitamin D is designed to assess both the safety and efficacy of potential doses (2,000 IU/day and 4,000 IU/day) in raising a vitamin D level to a normal range in a short period of time (e.g. 4 weeks or less) compared to 200 IU/day. In children with vitamin D insufficiency or deficiency who are at risk for severe asthma exacerbations, we hypothesize that both vitamin D supplementation with 4,000 IU/day and 2,000 IU/day will safely achieve normal vitamin D levels, but that the higher dose (4,000 IU/day) will result in a larger proportion of subjects achieving this level at 4 and 8 weeks.
Project Aim: To determine if intramuscular epinephrine is an effective adjunct to inhaled bronchodilators (β2 agonists) for children with severe asthma exacerbation. Hypothesis: IM epinephrine is an efficacious adjunct to inhaled bronchodilators (β2 agonists) for children with severe asthma exacerbation. Intervention: Subjects will be randomly assigned (50% chance) to receive a weight based dose of IM epinephrine 1:1000 or no adjunctive medication. The dose will be 0.2 mg for subjects 20-30 kg and 0.3 mg for subjects greater than 30 kg. This will be injected intramuscularly by an ED nurse into the anterior thigh muscles of the subject using a 1 ml syringe and a 23 gauge one inch needle. In addition to the study intervention, the standardized treatment pathway based on the current asthma guidelines in use at the investigator's center will be utilized. This pathway includes nebulized albuterol, ipratropium bromide, and systemic corticosteroids. The duration and dosages of these other interventions will be administered at the discretion of the treating provider.
We hypothesize that there is a statistically significant difference in miRNA profiling and expression of subjects with asthma upon its exacerbation compared to patient's baseline level or following effective treatment of an exacerbation of asthma. Therefore, plasma miRNA profiling may provide noninvasive, highly specific and sensitive biomarkers for asthma exacerbation's detection and treatment follow-up.
The purpose of this study is to evaluate the effectiveness of nebulized magnesium sulfate as a vehicle for albuterol in children with moderate to severe asthma exacerbation.
Previous investigations and anecdotal experience have shown safety and utility of Noninvasive Positive Pressure Ventilation/Bilevel Positive Airway Pressure (NIPPV/BiPAP) for the treatment of asthma in children. If NIPPV/BiPAP can be shown to have a beneficial effect in children with respiratory insufficiency, emergency department and ICU stays may be shortened, and the need for more invasive and dangerous airway procedures may be decreased. This would result in a change in the standard of care for asthma treatment in emergency departments. The investigators hypothesis is that the use of this new NIPPV, in conjunction with current standard of care therapies, in acute moderate to severe asthma exacerbations will lead to a more rapid improvement in patient ventilation, faster resolution of respiratory distress, and overall improved secondary outcomes.
This is a Phase 3, multicenter, randomized, double-blind, placebo-controlled, parallel-group study to evaluate the efficacy, safety, and immunogenicity of treatment with reslizumab in patients with eosinophilic asthma.
This is an investigator-initiated study in which Dr. Nadeau wrote the protocol and received funding from an Astra Zeneca grant to direct, perform, and monitor the study on her own with Stanford staff. We hypothesize that the budesonide/formoterol combination improves the efficacy of budesonide alone.
This study will establish the safety as well as demonstrate benefit of the addition of a LABA to an ICS by utilizing an endpoint (time to first severe asthma exacerbation) that informs on both safety and efficacy.
Hypothesis: A 2-day course of oral dexamethasone is the superior option for the resolution of symptoms and prevention of relapse in the emergency department (ED) management of mild-moderate asthma exacerbations.
The goal of this research is to use Helium-3 MRI to see the changes in airflow of the lungs at different times of an attack. These three stages are immediately after the attack, 1 month later and 4-6 months later.
This is a clinical study that is designed to study the effects of the supplemental intake of enriched omega-3 polyunsaturated fatty acids (fish oil) in patients with moderate to severe asthma. Some asthmatics produce a large amount of inflammatory leukotriene proteins-proteins that contribute to wheezing and inflammation in the airway. Inhibiting the detrimental effects of leukotrienes is a key goal of controller therapy in severe asthmatics. Some asthmatic patients appear to have specific mutations of the arachidonate 5-lipoxygenase (ALOX5) gene, one gene that regulates the production of the inflammatory leukotrienes. Omega-3 fatty acids can interfere with the arachidonic acid pathway and decrease the production of leukotrienes, and this may benefit moderate and severe asthma patients. Our hypothesis is that omega-3 fatty acid supplements, added on to a patient's asthma medication regimen, can decrease the number of minor asthma exacerbations compared to patients who do not receive the supplement. Furthermore, we believe that asthma patients with specific ALOX5 gene mutations will benefit most. We will enroll 30 asthma subjects to take part in this trial. They will undergo genotyping of the ALOX5 gene and be treated with omega3-fatty acids (fish oil) and placebo over a nine month period. We expect that this strategy will allow us to discover which moderate and severe asthma patients will benefit most from supplements of omega-3 fatty acids. Treatment of chronic diseases, such as asthma, is a key mission of the Center of Health and Nutrition Research.
The purpose of this study is to investigate mechanisms which cause acute asthma exacerbations by examining blood and airway secretions during an acute onset (sputum or tracheal aspirates). This pilot study is intended to uncover new mechanisms of asthma exacerbation and to generate hypotheses for future study. By collaborating with Genentech, we (scientists at UCSF) plan to incorporate the latest scientific findings into our work to discover and develop new treatments for asthma.
This is a double blind, controlled clinical trail testing whether three doses of 1.25 mg of nebulized levalbuterol in combination with three doses of 0.5mg of nebulized ipratropium will lead to greater bronchodilation than that achieved by three doses of nebulized 1.25 mg of levalbuterol alone every 20 minutes. The primary hypothesis of this study is that three doses of 1.25 mg of nebulized levalbuterol in combination with three doses of 0.5mg of nebulized ipratropium will lead to greater bronchodilation than that achieved by three doses of nebulized 1.25 mg of levalbuterol alone every 20 minutes. The secondary hypothesis is that the treatment combination of levalbuterol and ipratropium will lead to fewer hospitalizations than levalbuterol alone in patients with acute asthma exacerbation. Other secondary objectives include (1) evaluating the relationship between baseline (S)- albuterol levels and (R)- albuterol levels on presentation and FEV1, (2) the relationship between baseline (S)- albuterol levels and (R)- albuterol levels on presentation and change in FEV1,(3) time to event analysis for an improvement of 15%, 20%, 30%, 40%, and 50% in FEV1 from initial presentation value, (4) analysis of FEV1 at discharge.
