A Clinical Study to Evaluate the Safety, Tolerability and Pharmacokinetic Profile of TQC3302 Inhalation Spray in Healthy Adult Subjects

Phase 1TerminatedNCT07267130

Chia Tai Tianqing Pharmaceutical (Guangzhou) Co., Ltd.33 enrolled

Overview

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.

Outcomes

Primary Outcomes

Treatment Emergent Adverse Event

The incidence and severity of adverse events after treatment From the use of the investigational drug until the last study visit.

Time frame: From the use of the investigational drug until the last study visit, up to Day 14

The subject with abnormal security check

The frequency, incidence, and severity of laboratory tests, vital signs, physical examinations, electrocardiogram examinations, etc.

Time frame: From the use of the investigational drug until the last study visit, up to Day 14

Secondary Outcomes

Cmax after dose

The Cmax is the maximum observed plasma concentration of study drug

Time frame: Single dose：pre-dose, at 2,5,8,12,25,45 minutes,1,2,4,8,12,24, 48,72,120 hours after-dose (When using Budesonide Powder for Inhalation, there is no need to monitor at 48, 72, and 120 hours after the end of administration)

Area Under the Concentration-Time Curve From 0 to Last Observation (AUC [0-t])

To characterize the pharmacokinetics of TQC3302 by assessment of area under the plasma concentration time curve from the first dose to a certain time point

Area Under the Concentration-Time Curve From Zero to Infinity (AUC [0-infinity])

To characterize the pharmacokinetics of TQC3302 by assessment of area under the plasma concentration time curve from 0 extrapolated to infinity.

Time to reach maximum (peak) plasma concentration following drug administration (Tmax)

To characterize the pharmacokinetics of TQC3302 by assessment of time to reach maximum plasma concentration after single dosing.

Half-life (t1/2)

Terminal phase elimination half-life (T1/2) is the time required for half of the drug to be eliminated from the plasma.

Apparent volume of distribution (Vd/F)

Apparent volume of distribution of the TQC3302 in plasma.

Apparent clearance (CL/F)

Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the body.

Peak concentration (Cmax) after the first administration

The Cmax is the maximum observed plasma concentration of study drug.
