A Study Evaluating the Efficacy of Budesonide, Glycopyrronium and Formoterol Fumarate Metered Dosed Inhaler on Cardiopulmonary Outcomes in Chronic Obstructive Pulmonary Disease (NCT06283966) is a Phase 3 interventional studying COPD (Chronic Obstructive Pulmonary Disease), sponsored by AstraZeneca.

About This Trial

This study will evaluate the effect of triple ICS/LAMA/LABA therapy with BGF MDI 320/14.4/9.6 μg on cardiopulmonary outcomes relative to LAMA/LABA therapy with GFF MDI 14.4/9.6 μg in a population with COPD and elevated cardiopulmonary risk.

What Stage of Research Is This?

Phase 3 trials confirm efficacy and safety in large patient groups (often 300–3,000+) and form the evidence base for an FDA approval submission. For COPD (Chronic Obstructive Pulmonary Disease), Phase 3 studies typically randomize participants between the investigational treatment and either a placebo or current standard of care. A successful Phase 3 result is the threshold most treatments need to clear before regulatory approval.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

Target enrollment of 5,000 participants makes this one of the larger COPD (Chronic Obstructive Pulmonary Disease) trials currently registered. Trials at this scale are typically global, run across many sites, and designed to generate the definitive evidence package for an FDA approval submission or a label expansion.

Frequently Asked Questions

What is the NCT06283966 clinical trial studying?

This study will evaluate the effect of triple ICS/LAMA/LABA therapy with BGF MDI 320/14.4/9.6 μg on cardiopulmonary outcomes relative to LAMA/LABA therapy with GFF MDI 14.4/9.6 μg in a population with COPD and elevated cardiopulmonary risk. The full protocol is registered on ClinicalTrials.gov and includes the primary outcome measures, eligibility criteria, and study endpoints.

Who can participate in NCT06283966?

Eligibility for this trial depends on the specific inclusion and exclusion criteria set by the sponsor. The plain-English summary above translates the most important criteria into accessible language; the official clinical text is preserved in the collapsible section underneath. Whether you fit any specific trial is a medical decision your doctor needs to confirm — bring the trial information to your treating physician for a full review against your medical history.

How do I contact the trial site for NCT06283966?

Contact information registered with ClinicalTrials.gov is shown in the sidebar of this page. Before reaching out, confirm with your treating physician that this trial is appropriate for your situation. The trial site will then walk you through the screening process to determine final eligibility.

Is participating in a clinical trial safe?

Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening. The informed consent document for any specific trial details the known risks and what to expect. Discuss those risks with your physician before deciding whether to participate.
