Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants With a Predicted Effect on aVß6 PET ( Positron Emission Tomography) in Lungs After Administration of Drug.	Assessment of the primary endpoint was made using standard methods for quantifying the amount to PET tracer bound to the avß6 integrin receptor in the lungs before and after administration of study drug and PK/PD modeling.	Following 1 day of dosing
Secondary	Safety and Tolerability of PLN-74809 as Measured by the Number / Percentage of Adverse Events	Adverse events were collected from the time the participant signs the Informed Consent Form until the last day of visit (Day 14).	From screening to 1 week following the administration of PLN-74809
