Filter by:A Phase 1 investigation will be performed to test the safety of two doses of bone marrow-derived MSCs (20,000,000 and 100,000,000) administered via peripheral intravenous infusion.
Current corticosteroid regimens for children hospitalized with asthma typically include a 5-day course of prednisone or prednisolone. However, these medications taste poorly and are associated with vomiting and poor compliance. Outpatient evidence suggests that a 2-day course of dexamethasone is as effective as a longer course of prednisone and prednisolone, and better tolerated. Studies in hospitalized patients are lacking. The investigators' primary objective is to determine the feasibility of a non-inferiority trial, comparing 2 days of dexamethasone to 4 days of inpatient prednisone/prednisolone for inpatient asthma treatment. The investigators also wish to determine the feasibility of 1) enrolling patients upon admission to hospital, 2) asking patients and/or caregivers to complete a symptom weekly for 4 weeks, 3) reassessing patients post hospital discharge, 4) successfully completing phone follow up 4 weeks post hospital discharge, and 5) collecting health utilization data post hospital discharge. This study will inform a future multi-site trial comparing prednisone/prednisolone to dexamethasone in inpatient asthma treatment. It has the potential of improving the delivery of care in asthma, by improving compliance with a mainstay of treatment. It will also enhance collaboration within Ontario pediatric hospitals, facilitating knowledge translation and standardization of care across institutions.
The purpose of this study is to establish the influence of the non-steroidal candidate-drug pemirolast on allergen-induced airway obstruction and inflammation in allergic subjects with asthma. Pemirolast is an orally available inhibitor of the release of mast cell mediators. The study will therefore test the hypothesis that global inhibition of the mast cell, resulting in decreased production of most of its mediator molecules, will provide a highly significant anti-asthmatic effect.
This study evaluates blood type 2 innate lymphoid cells in participants with mild to moderate asthma and participants with chronic urticaria as compared to healthy adult participants.
This is a multicenter, open-label (OL) extension study to obtain additional long-term safety data for subcutaneous (sc) administration of reslizumab treatment administered at a fixed dose of 110 mg in patients 12 years of age and older with severe eosinophilic asthma who completed the treatment period of a placebo-controlled Phase 3 trial of sc reslizumab. The study consists of a screening/baseline visit followed by a 36-week OL treatment period and a 15-week follow-up period.
This study was a 2-treatment period, randomized, multicenter parallel-group study. The overall purpose of this study was to provide long- term safety data for fevipiprant (QAW039) (Dose 1 and Dose 2), compared with placebo, when added to the Global Initiative for Asthma (GINA) steps 3, 4, and 5 standard-of-care (SoC) asthma therapy (GINA 2016), in patients with moderate-to- severe asthma. The purpose of this study was to provide long-term safety data for QAW039 150 mg once daily and 450 mg once daily, compared with placebo, when added to GINA steps 3, 4, and 5 standard-of-care asthma therapy (GINA 2020) in adult and adolescent (≥12 years) patients with moderate-to-severe asthma. The study included 2 cohorts of patients: 1. Rollover patients who had completed any of the four Phase 3 pivotal efficacy studies with QAW039 (QAW039A2307, QAW039A2314, QAW039A2316, or QAW039A2317, hereafter referred to as Studies A2307, A2314, A2316, and A2317), thus providing data for a longer duration of exposure, and 2. New patients who had not previously participated in a study of QAW039, permitting an increase in the number of patients with long-term exposure to QAW039. By including these 2 categories of patients, the total number of patients treated with QAW039 as well as the duration of exposure to QAW039 treatment was substantially increased, supporting evaluation of the safety profile of QAW039.
The purpose of this proof-of-concept study is to determine the effect of Intestinal Microbiota Depletion or Intravenous Administration of C1-inhibitor on Inflammation and Coagulation after Bronchial Instillation of House Dust Mite Allergen and Lipopolysaccharide in Allergic Asthma Patients
This study is designed to identify Dermatophagoides farinae, or Der f, sensitive asthmatics who demonstrate a late phase asthmatic response after Der f inhalation. These subjects may be invited to participate in a planned future study investigating novel asthma treatments.
This study investigates the propagation of sound from a source in the chest to the chest wall. The methodology of the study will be to place a sound source at a known location in the chest and measure the acoustic response on the posterior chest wall with an acoustic sensor array. The sound source will be created by playing sound down the working channel of a bronchoscope and located anatomically using direct imaging. Subjects will be selected for the study by asking patients undergoing a bronchoscopy procedure whether they would be willing to take part in the experiment in addition to their standard procedure. Procedures will take place in the Bronchoscopy Unit at Addenbrooke's hospital in Cambridge. The Unit runs regional speciality clinics in severe chronic obstructive pulmonary disease, asthma, lung cancer, bronchomalacia and interstitial lung disease and has a nationally significant interventional bronchoscopy service. A subsidiary part of the study (Part A) will collect sound recordings from healthy volunteers and patients with common respiratory diseases using the same acoustic sensor array. This is to create a database of lung sounds and quantify inter-subject variability. The study will last approximately 30 months.
RP3128 is a calcium release activated calcium (CRAC) channel modulator. The purpose of this study is to evaluate the safety, tolerability and pharmacokinetics of single and multiple ascending dose(s) of RP3128 in healthy volunteers and to evaluate the effect on late phase asthmatic response to allergen challenge in patients with mild asthma.
