Brief summary: This is the first-in-human, single-center, randomized, double-blinded, placebocontrolled, single-dose and multiple-dose escalation Phase Ia study

Detailed description: Single ascending dose (SAD), healthy participants will be randomized to receive a single inhalational dose of either XW001 or placebo in each of the planned SAD cohorts. Multiple ascending dose (MAD), healthy participants will be randomized to receive inhalational doses of XW001 or placebo in each of the planned MAD cohorts.
