A Clinical Study to Evaluate the Safety, Tolerability and Pharmacokinetic Profile of TQC3302 Inhalation Spray in Healthy Adult Subjects
Recruiting now · Phase 1
Conditions studied: Chronic Obstructive Pulmonary Disease
In brief
Groups 1, 3, 4, 5 and 6 of this research team adopted a single-center, open-label design. Group 2 used a three-sequence, three-period crossover design, where participants in this dose group were randomly assigned to the three sequences in a 1:1:1 ratio to undergo three-period crossover administration. Healthy adult subjects were selected to use TQC3302 inhalation spray to evaluate the safety, tolerability, and pharmacokinetic characteristics of single and multiple inhalations of TQC3302 inhalation spray in healthy participants.
