Tharros Study

What is the Tharros Study About?

This study is comparing how well BGF (brand names BREZTRI and TRIXEO) or GFF (brand name BEVESPI) may help prevent COPD flare-ups and serious heart events in people with COPD. People with COPD have a higher risk of heart problems and serious heart events than people without COPD.
Inhaled corticosteroids (ICS) are known to help prevent COPD flare-ups. It is thought that combination treatments with inhaled corticosteroids (ICS) may help reduce serious heart events. For this reason, we will compare a treatment with an ICS (BGF) against one without an ICS (GFF).


Adults aged 40-80 with a COPD diagnosis who have never taken an inhaled corticosteroid for their COPD.
