15 Clinical Trials for Various Conditions
Respiratory signs and symptoms consisting of wheeze, cough, and breathlessness are obtained in a manual fashion through history taking and physical examination by the healthcare professional. Auscultation of the lung assesses airflow through the trachea-bronchial tree and is helpful in diagnosing various respiratory disorders. AeviceMD is a wearable device that can acquire and process lung sounds, thus assisting in the detection of abnormal lung sounds. The primary objective of this study is to determine if AeviceMD can detect wheeze of pediatrics and adults as accurately as a physician through auscultation. The secondary objective is to investigate if AeviceMD can be used for remote auscultation of breath sounds.
The goal of this observational study is to learn about further wheezing in infants with RSV infection.. The main question it aims to answer is: If infant factors, the infant immune response in the nose and the bacteria that reside in the nose at the time of primary RSV infection can predict/classify infants with recurrent wheezing during the following year. A secondary aim is to identify infant immune response factors in the nose and patterns of bacteria in the nose during primary RSV infection that may help us understand why recurrent wheezing occurs. Researchers will compare infants with repeated episodes of wheezing to infants who do not have further wheezing. Participants will be full term infants with their first RSV infection. We will collect information on the pregnancy and birth history as well as the signs and symptoms of RSV infection. Two nasal swabs and a nasal wash will be collected from the infants. Six weeks following the RSV infection we will begin contact with the families biweekly to determine if the infant has recurrent wheezing confirmed by a medical provider. Follow-up will continue for approximately 1 year, through a second winter season.
The WheezeScan sensitivity and specificity are set to statistically prove equal to or higher values than the predicate PulmoTrack device model 2020.
The purpose of this study is to assess the incidence and associated healthcare utilization of RSV-associated, suspected LRTI in a general population of infants from birth up to 2 years of age, and also to assess the accuracy of a newly developed LRTI case definition and severity scale compared to two existing definitions. The study will also assess the population attributable risk percent of RSV LRTI on the development of wheeze and asthma from 0 to 6 years of age.
This is a parallel, Phase 3, 2-arm study to evaluate the efficacy and long-term safety of dupilumab treatment in children 2 to \<6 years of age with uncontrolled asthma and/or recurrent severe asthmatic wheeze. The study will be conducted in 2 parts. Part A will be a 52-week, randomized, double-blind, placebo-controlled study to assess the safety and efficacy of dupilumab in children aged 2 to \<6 years old with uncontrolled asthma and/or recurrent severe asthmatic wheeze. At the end of Part A, all eligible participants will be offered participation in Part B, an optional open-label extension phase. Study details include: Part A: The study duration of part A will be up to 68 weeks consisting of a 4-week Screening, a 52week treatment period, and a 12-week post-treatment follow-up period. For participants who will chose to participate in Part B, the study duration will be up to 120 weeks (additional 52-week treatment period). Part B: For participants who will choose to participate in Part B, the study duration will be up to 120 weeks (Part A \[4-week Screening and a 52-week treatment period\] plus additional 52-week treatment period and a 12-week post-treatment follow-up period).
Asthma is the most common chronic disease of children. A short (3-5 day) course of a short-acting steroid such as Prednisone or Prednisolone has long been the standard of care for asthma exacerbation. Dexamethasone efficacy in asthma exacerbation has been studied in the outpatient setting and was found to be as effective as Prednisone. Dexamethasone has the advantage of shorter course, more compliance, and more tolerable. This has led many emergency departments to provide a 1-2 dose course of Dexamethasone on discharge. Thus, many inpatients have received a first dose of Dexamethasone prior to reaching the inpatient unit, leading to confusion about the best plan for these patients. Many hospitalist pediatricians continue to give a 5-day total course with Prednisone, but some patients have begun to receive a second dose of Dexamethasone 24 hours after the first dose. To our knowledge, no studies have been done to compare the efficacy of these two protocols in pediatric patients requiring hospitalization. The hypothesis is that a second dose of Dexamethasone is as effective as four additional days of Prednisone in hospitalized children with asthma exacerbation. This is an open label, randomized control study comparing these treatments in children age 2-18 hospitalized with asthma exacerbation who have received a first dose of Dexamethasone.
Vitamin C supplementation (500 mg per day) given to pregnant women who can not quit smoking will improve the pulmonary function tests in their offspring measured at 3 months of age.
The overall aims of this protocol are to determine whether prenatal supplementation with vitamin C to pregnant smokers can improve pulmonary function at 10 years of age in their offspring. This is an additional continuation of the Vitamin C to Decrease Effects of Smoking in Pregnancy on Infant Lung Function (VCSIP) trial, to follow the offspring through 10 years of age. The hypothesis for this protocol is an extension of the VCSIP trial that supplemental vitamin C in pregnant smokers can significantly improve their children's airway function tests. The investigators aim to demonstrate sustained improvement in airway/pulmonary function and trajectory through 10 years of age.
In a randomized clinical trial (RCT) published in JAMA, the investigators have provided evidence that vitamin C supplementation (500 mg daily during pregnancy) ameliorates the effects of maternal smoking during pregnancy on offspring lung function and subsequent incidence of wheeze by 48% through 1 year of age. The investigators are currently completing a second RCT of vitamin C supplementation in pregnant smokers with more robust measures of pulmonary outcomes. The purpose of this ECHO application is to combine these 2 focused, interventional cohorts to allow critical longitudinal follow-up of respiratory outcomes in these children including the study of pulmonary function test (PFT) trajectories and incidence of recurrent wheeze/asthma from infancy through early adolescence in offspring of pregnant smokers randomized to vitamin C versus placebo.
The overall aims of this protocol are to determine whether prenatal supplementation with vitamin C to pregnant smokers can improve pulmonary function and decrease wheeze at 5 years of age in their offspring. This is a continuation of the VCSIP trial, to follow the offspring through 5 years of age. The hypothesis for this protocol is an extension of the VCSIP trial that supplemental vitamin C in pregnant smokers can significantly improve their children's PFTs and decrease the incidence of wheeze.
A multi-center, Phase IIb, double-blind, randomized, placebo controlled, parallel-group, repeated-dose study in male and female patients with moderate to severe asthma in which patients will be stabilized on AEROVANT then doses of inhaled corticosteroids and LABA will be tapered. The hypothesis is that AEROVANT will improve asthma symptom control and decrease the need for inhaled corticosteroids and LABA, thus improving exacerbation incidence compared to placebo. Incidence of asthma exacerbation is the primary endpoint.
Early life exposures now appear to be important in modulation of the immune response and tendency to develop asthma. We plan to enroll a cohort of children at birth to study early life factors in the development of wheezing and respiratory illness during the first six years of life in Mexico City. In particular, we will consider the role of early diet (particularly antioxidant intake, lactation and obesity), infections, dust mite and cockroach antigens, traffic related air pollution, and environmental tobacco smoke. We will also consider the potential modifying effect of genetic predisposition with respect to the exposures of interest. Approximately 6,800 children will be enrolled at birth. The goal is to follow the cohort though age 6. To increase the number of expected cases of asthma, we will partially enrich the cohort for increased risk of asthma by virtue of having a parent with doctor diagnosis of asthma or allergies; the remaining cohort will not be enriched to preserve generalizability. Pregnant women enrolled in a prepaid health plan in Mexico City (the Insituto Mexicano de Seguridad Social, henceforth referred to as IMSS) will be screened for the study and invited to enrolled their newborns when they come for delivery at one of two IMSS hospitals. An initial home visit during the first three months of life will include assessment of environmental exposures and infant diet. Children will be followed through age six with yearly home visits, monitoring of acute lower respiratory illness during the first year of life and periodic review of the IMSS medical records. We have chosen Mexico City because of the relatively low rates of asthma in the face of prevalent exposures to factors that are thought to increase asthma risk in urban areas in the United States. These include dust mites, cockroach, airborne pollutants and social factors such as low income and young maternal age. This pattern suggests that protective factors may be operating in Mexico City that could shed light on the etiology of worldwide childhood asthma epidemic. Potential candidates include exposure to certain early infections that shift the developing immune system away from the pattern of allergic asthmatic response. We are also especially interested in potential protective effects of early nutrition. Exposure to ozone in this population is the highest in North American and thus antioxidant intake may be especially important. In order to evaluate these protective hypotheses, we will also collect information on risk factors believed to be related to increased risk of asthma in US cities such as allergens, traffic related air pollutants, and lower respiratory infection with respiratory syncytial virus.
This study will test the effectiveness of an investigational treatment for patients with ragweed-induced asthma, sometimes called fall seasonal asthma. The treatment being tested is a series of anti-ragweed shots. The purpose of the study is to determine whether a short series of injections with Amb a 1-immunostimulatory oligodeoxyribonucleotide conjugate (AIC) can cause a long-lasting reduction in the symptoms of asthma that are caused by fall hay fever allergies.
The purpose of this study is to learn more about how asthma develops in early childhood. This will help doctors understand how to prevent and treat asthma better.
Karmel Sonix Ltd has developed the Personal WheezoMeter a hand-held pulmonary sounds analyzer that utilizes contact sensors to acquire, amplify, filter, record and quantify the presence of wheezing. When used to monitor conditions such as asthma, this device should be used under the direction of a physician or licensed healthcare professional. The device is intended for use with pediatric and adult patients in both home and clinical settings. The purpose of the study is to determine whether Wz% and change in Wz% correlate with symptoms and change in symptoms at least as well as FEV1 and change in FEV1.0. Additional information to be obtained from the study will be to determine whether there is a symptom threshold at which a patient seeks rescue medications and if so, to determine the value of Wz% and FEV1.0 at this point (Wz%, FEV1.0 thresholds). The study will also provide information on the within patient and whole group correlations between Wz% and FEV.
