Additional Inclusion Criteria for Healthy Participants

\- Participants must have a pre-bronchodilator FEV1 ≥80% predicted (using GLI Global predicted values17) and an FEV1 / FVC ratio of \>70% absolute at screening.

* Participants must have either a positive skin prick test with a wheal diameter of ≥3mm greater than control test at 15 minutes, and/or a blood eosinophil count of \> 200 cells / µL and/or a FeNO level of \> 25 ppb at screening.
* Participants must have a pre-bronchodilator FEV1 ≥65% predicted at screening
* Participants must be using SABA alone or inhaled corticosteroids (ICS) with SABA or ICS with formoterol as reliever therapy, AND/OR regular use of low to mid-dose ICS with or without LABA at a stable dose for at least 3 months prior to randomization to control their asthma.

Part B only

* Participants must have an ACQ-6 score of \> 0.75 at screening.
* Participants must have a history of asthma worsening in the previous 2 years, in response to a cold or respiratory infection, as confirmed by the participant.

Exclusion Criteria:

Exclusion Criteria for all Participants

* History or presence of any clinically relevant acute or chronic medical or psychiatric condition that could interfere with the participant's safety during the clinical trial, expose the participant to undue risk or interfere with the participants ability to successfully conduct the trial, as judged by the Investigator.
* Any significant abnormality altering the anatomy of the nose in a substantial way or nasopharynx that may interfere with the trial at time of screening.
* Any clinically significant history of epistaxis (large nosebleeds) within the last 3 months of the first administration of IMP and/or history of being hospitalized due to epistaxis on any previous occasion.
* Any nasal or sinus surgery within 3 months of the first administration of IMP
* Any signs of upper respiratory tract infection within 6 weeks of screening or prior to first administration of IMP
* Current or previous use of tobacco, nicotine products or e-cigarettes in the past 6 months prior to screening.
* Smoking history of \> 5 pack years.

Additional Exclusion Criteria for Participants with Asthma

* Any asthma exacerbation on their current asthma controller medication requiring oral/systemic corticosteroids within 8 weeks of randomization, or that resulted in overnight hospitalization requiring additional treatment for asthma within 3 months of randomization.
* Difficult-to-treat or severe asthma requiring the maintenance use of add-on biologic Type 2 targeted treatments including anti-Immunoglobulin E, anti-IL4 receptor, anti-IL5, anti-IL5 receptor, and anti-Thymic Stromal Lymphopoietin
