Who may not be able to join:

- You are unable or unwilling to stop taking medications known to affect the heart's electrical rhythm
- You have a current or past history of lung inflammation or scarring (interstitial lung disease), or scans during screening suggest you might have this condition
- You have serious underlying lung problems, including a blood clot in the lungs within the past 3 months, severe asthma, severe chronic lung disease (COPD), restricted lung function, or you currently need extra oxygen
