A Study Evaluating the Efficacy of Budesonide, Glycopyrronium and Formoterol Fumarate Metered Dosed Inhaler on Cardiopulmonary Outcomes in Chronic Obstructive Pulmonary Disease
(THARROS)
What this study is about
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.
View original scientific description

Interventions
DRUG
BGF MDI 320/14.4/9.6 μg
Budesonide, glycopyrronium, and formoterol fumarate pressurized inhalation suspension
DRUG
GFF MDI 14.4/9.6 μg
Glycopyrronium and formoterol fumarate pressurized inhalation suspension
Primary outcome measures
Time to first severe cardiac or COPD event
Time frame: Up to 3 years
Evaluate the effect of combination triple therapy (BGF MDI 320/14.4/9.6 μg) compared with dual bronchodilator therapy (GFF MDI 14.4/9.6 μg) on cardiopulmonary outcomes.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Male or female participants must be 40 to 80 years of age inclusive, at the time of signing the ICF.
- Demonstrate acceptable MDI administration technique at Visit 1 (V1) and Visit 2 (V2)
- A diagnosis of COPD confirmed by a post-bronchodilator FEV1/FVC ratio \< 70% at V1.
- Current or former smokers with a history of at least 10 pack-years of cigarette smoking; defined as (number of cigarettes per day/20) x number of years smoked. Previous smokers are defined as those who have stopped smoking for at least 6 months prior to V1.
- A baseline peripheral blood eosinophil count of ≥ 100 cells/mm3 assessed at Visit 1 by the central laboratory
- A CAT score of ≥ 10 at Visit 1.
- Participant must fulfill at least 1 of the 4 CV disease/risk factor criteria below \[(a), (b), (c), or (d)\]:
- : Established CV Disease
- : Combination of CV risk factors:
- Hypertension
- Diabetes Mellitus
- Chronic Kidney Disease
- Dyslipidemia
- : High risk of CV disease determined using an established CV risk assessment tool.
- : CT coronary Artery Calcification
- Willing and, in the opinion of the investigator, able to adjust current COPD therapy, as required by the protocol.
- Willing to visit at the study site or participate in virtual visits as required per the protocol to complete all study assessments.
- A female is eligible to enter and participate in the study if the female is of:
- Non-childbearing potential: either permanently sterilized or who are post-menopausal.
- Childbearing potential: has a negative serum pregnancy test at V1 and must use one highly effective form of birth control.
- Capable of giving signed informed consent, which includes compliance with the requirements and restrictions listed in the ICF and in the protocol.
Exclusion criteria
- Active diagnosis of asthma within the past 5 years (previous diagnosis as a child or adolescent are eligible), asthma-COPD overlap, or any other chronic respiratory disease other than COPD such as alpha-1 antitrypsin deficiency, active tuberculosis, lung fibrosis, sarcoidosis, interstitial lung disease, and pulmonary hypertension.
- End-stage renal disease requiring renal replacement therapy
- History of heart or lung transplant or actively listed for heart or lung transplant.
- Implanted left ventricular assist device or implant anticipated in \< 3 months.
- History of lung cancer and/or treatment for lung cancer within the 5 years prior to Visit 1.
- Unstable or life-threatening cardiac disease - participants with any of the following at Visit 1 would be excluded:
- An MI or unstable angina in the last 8 weeks
- Unstable or life-threatening cardiac arrhythmia requiring intervention in the last 8 weeks. NOTE: Any participant who experiences unstable or life-threatening cardiac disease during the run-in period will be excluded but can be rescreened 8 weeks after the resolution of the event.
- Pneumonia and/or moderate or severe COPD exacerbation that has not resolved at least 8 weeks prior to Visit 1
- Any life-threatening condition, including malignancy, with a life expectancy \< 5 years, other than CV disease or COPD, that might prevent the participant from completing the study.
- Use of maintenance ICS treatment within the past 12 months.
- Unable to abstain from protocol-defined prohibited medications
- Participation in another clinical study with a study intervention administered in the last 30 days or 5 half-lives, whichever is longer prior to Visit 1 (any other investigational product that is not identified in protocol is prohibited for use during the duration of the study).
- Participants with a known hypersensitivity to LAMA, LABA or ICS or any component of the MDI.
- Involvement in the planning and/or conduct of the study (applies to both AstraZeneca staff and/or staff at the study site).
- Judgment by the investigator that the participant should not participate in the study if the participant is unlikely to comply with study procedures, restrictions, and requirements.
- Previous randomization in the present study.
- For females only - currently pregnant (confirmed with positive pregnancy test) or breastfeeding

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
