Filter by:The purpose of this study is to examine the effects of multi-dose regimens of IPI-145 on lung function in mild asthmatic subjects following allergen challenge.
This is a randomized, double-blind, placebo-controlled, repeat dose, 2-period, incomplete block, crossover, safety and pharmacokinetic (PK) study to evaluate 3 once-daily doses of umeclidinium (GSK573719; UMEC) in adolescent asthma subjects aged 12 through 17 years,) who are currently using asthma medications that do not contain inhaled corticosteroids (non-ICS). The objectives are to investigate safety and tolerability, and PK after a 7-day (+2) repeat once-daily dose of UMEC (15.6, 62.5, and 250 mcg) in asthmatic adolescent subjects. Safety endpoints will include reported adverse events, vital signs, ECGs, clinical laboratory tests, and rescue albuterol use. The PK endpoints will include serial PK (plasma and urine) concentrations and derived parameters. Twenty four subjects will be randomized to participate in the study for up to 7 weeks (including: an initial screening visit, a 7 to 14-day run-in, and 2 treatment periods each of 7 (+2) day duration, with a washout period of 7-14 days between treatment periods). There will be a Follow-up Visit approximately one week after the end of the second treatment period. Subjects will refrain from using rescue medication for 4 hours prior to any clinic visits, unless for emergency. During each treatment period, study medication will be taken once in the morning until the morning of Day 7 (+2 days) when subjects will return to the clinic for study assessments and take the last dose of study medication. On Day 7 (+2), subjects will remain in the clinic overnight for serial assessments (ECG, and PK plasma and urine samples over the 24-hours).
Phase IIa, single-centre, open-label, single-arm study, to evaluate the inspiration profile through the NEXThaler® device in adult asthmatic patients with varying degrees of disease control.
In this trial the safety, tolerability, pharmacokinetics and exploratory pharmacodynamics of multiple dose administration of BI 144807 will be investigated in otherwise healthy, controlled asthmatic patients
This project aims to improve guideline-based asthma care using enhanced communication and screening tools, telemedicine and directly observed therapy of preventive medications in city schools. Web-based screening will be used to identify children with persistent or poorly controlled asthma and to send reports to the child's primary care doctor. Children in the SB-TEAM group will receive a telemedicine asthma assessment in school and be prescribed a daily preventive asthma medication to be taken through school-based directly observed therapy. The overall aim of this study is to evaluate the use of the SB-TEAM intervention for improving guideline based care, enhancing adherence to effective preventive medications and at reducing morbidity among young urban children with asthma.
The objective of this study is to evaluate the effect of the combination of formoterol and beclometasone dipropionate in a dry powder inhaler (NEXThaler®) on central and peripheral airway dimensions in asthmatic patients. Therefore Computational Fluid Dynamics (CFD) will be used. Further more, the effect of this combination therapy on lung function (spirometry, resistance and diffusion), the Asthma Control Test (ACT™) and the Asthma Control Questionnaire (ACQ) will be assessed and the safety will be evaluated.
The main objective of this study is to determine whether the use of the PARI LC Sprint Sp nebulizer in the treatment of asthma in children under 36 months reduces the duration of hospitalization.
Objective: To explore the utility of Fractional Exhaled Nitric Oxide (FeNO) compared with Methacholine Challenge (MCC) testing in assessing patients with suspected but undiagnosed asthma Number of participants: Approximately 50 subjects will be enrolled Reference product: NIOX MINO® Instrument (09-1100) Performance assessments: FeNO measurements will be performed according to the "Perform FeNO Measurement" guidelines on page 7 of the NIOX MINO® User Manual. MCC testing will be performed according to the ATS guidelines and the allergy and asthma specialists procedure for conducting MCC tests Safety assessments: The Investigator is responsible for the detection, reporting, and documentation of events meeting the definition of an Adverse Event (AE) and/or Serious Injuries as provided in this clinical investigation plan from the time that informed consent has been provided and during the study period Criteria for evaluations: This is an exploratory study and there are currently no plans for a formal statistical analysis. Information gained from this study may used to design and power subsequent studies in patients with suspected but undiagnosed asthma. Information collected will be summarized in a clinical study report
In real life, the investigators will be using different strategies including SMART therapy or other ICS/LABA (medium and high dose) therapy and measure the efficacy for asthma control.
Asthma has become considerably more prevalent and severe in the U.S. during the last 40 years, particularly affecting youth in urban areas, yet the reasons for this are not clear. There is increasing evidence that vitamin D insufficiency contributes to more severe asthma through increased risk of respiratory infections and decreased sensitivity to glucocorticoids. Indeed, low vitamin D levels are linked with the need for exogenous glucocorticoids and increased asthma severity. Particularly relevant to health disparities, we showed a strong association between vitamin D insufficiency and asthma in urban African American (AA) youth. Importantly, AA youth in ours and other studies had lower vitamin D levels than non-AA participants. Because AA youth residing in urban Washington, DC have markedly worse asthma than other racial/ethnic groups (e.g. prevalence rate 20% higher than the national rate 15 and emergency department utilization rates up to 5 times the national rates and nearly 10 times the Healthy People 2010 target rate), we will utilize our access to this population at the extreme of asthma disparities to examine the contribution of vitamin D to disparities in the chronic control and acute severity of asthma. The overall goal of this study is to provide critical epidemiological/molecular information that will inform the interpretation of ongoing and impending randomized clinical trials of vitamin D supplementation in asthma, especially with regard to urban AA youth with asthma. We hypothesize that low serum 25-hydroxyvitamin D [25(OH)D] levels are associated with poor chronic asthma control, worse acute asthma severity, and glucocorticoid insensitivity. The knowledge generated by the experiments in this application will be crucial to translation of this inexpensive, easily-accessible, and thereby potentially disparity-reducing prospective therapy for asthma.
