3. Uncontrolled epistaxis within 2 months prior to screening;
4. Concomitant major chronic diseases that are uncontrolled and that, in the opinion of the investigator, may increase the safety risk of the participant's participation in this study;
5. Participants with other concomitant active or clinically significant respiratory diseases that may significantly affect the study, as judged by the investigator;
6. Participants with cardiovascular disease, and whose participation in this trial may affect the safety of the participants or the analysis of the study results at the discretion of the investigator.
