2. Any clinical laboratory test result outside of the reference ranges considered by the Investigator as clinically significant and that may obscure the study data or interfere with the participant's safety.
3. Participant with a history or evidence of a clinically significant pulmonary condition (other than asthma), including significant restrictive findings on pulmonary function testing, chronic bronchitis, emphysema, bronchiectasis, pulmonary fibrosis, or any other related condition that may obscure the study data (e.g., gastroesophageal reflux and vocal cord paralysis/dysfunction).
