This research aims to compare the effects of two inhalers, budesonidealbuterol metered-dose inhaler BDA MDI and albuterol sulfate metered-dose inhaler AS MDI, both used as needed, in adolescents aged 12 to 17 years with asthma. The study focuses on their impact on the annual rate of severe asthma attacks in participants who have a documented diagnosis of asthma and at least one severe exacerbation in the past year. This is a randomized, double-blind, multicenter Phase IIIb trial. Participants are randomly assigned in equal numbers to receive either BDA MDI 160180 micrograms 2 puffs of 8090 micrograms or AS MDI 180 micrograms 2 puffs of 90 micrograms as needed, alongside their usual maintenance asthma therapy. The study includes a 7 to 28-day screening period, a 52-week treatment period, and a safety follow-up lasting 7 to 14 days after treatment ends. Additionally, a pharmacokinetic sub-study involves a single dose of open-label BDA MDI administered at a separate visit after safety follow-up. During the study, participants will be monitored through regular assessments including lung function tests such as peak expiratory flow, evaluation of asthma exacerbations, and safety checks for adverse events. The main outcome measured is the annualized rate of severe asthma exacerbations over the 52-week treatment. Safety follow-up and pharmacokinetic evaluations will further assess drug concentrations and participant well-being. Overall participation lasts from screening through safety monitoring after treatment completion.

Researchers are evaluating the long-term performance and reliability of Medtronics market-released cardiac rhythm therapy products, including leads and devices used for pacing, sensing, or defibrillation. This observational study aims to analyze how well these cardiac devices function over time by measuring survival probabilities and tracking device-related complications. The study applies to patients with conditions such as arrhythmia, bradycardia, heart failure, and sinus tachycardia. The study includes all Medtronic market-released cardiac leads and implantable devices such as pacemakers IPG, implantable cardioverter defibrillators ICD, and cardiac resynchronization therapy CRT devices. Participants either have a new implant or are within 30 days post-implantation. Data from prior qualifying Medtronic studies with complete follow-up may also be included. The study continuously monitors these products from the time of implant until the lead is no longer in use due to patient exit, death, or device deactivation. Participants provide consent for data access and use, and their health information is tracked over the long term. Researchers evaluate lead-related complications and product survival throughout the study period, which began in 1983 and is ongoing until 2040. The study does not involve additional treatments but collects follow-up data to assess device performance and safety over time.
