This study has been completed.
Information provided by (Responsible Party):
AstraZeneca Identifier:
First received: August 17, 2009
Last updated: January 13, 2015
Last verified: November 2014
The aim of the study is to assess the safety, tolerability, pharmacokinetics and pharmacodynamics of AZD5423 following single ascending dose administrations in healthy male subjects.

Condition Intervention Phase
Healthy Volunteers Drug: AZD5423 Drug: Placebo Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Care Provider, Investigator)
Primary Purpose: Basic Science
Official Title: A Phase I, Single Centre, Double-blind, Randomised, Placebo-controlled, Parallel-group Study to Assess the Safety, Tolerability and Pharmacokinetics of Inhaled AZD5423 After Single Ascending Doses in Healthy Male Subjects

Further study details as provided by AstraZeneca:

Primary Outcome Measures:
  • Safety variables (ECG, adverse events, blood pressure, pulse, body temp, safety lab), lung function and physical examination [ Time Frame: Frequent sampling occasions during study days ]

Secondary Outcome Measures:
  • Pharmacokinetics - Maximum plasma concentration (Cmax), time to Cmax (tmax), area under the plasma concentration-time curve from zero to the time of the last measurable concentration [AUC(0-t)] and from zero to infinity (AUC) [ Time Frame: Frequent sampling occasions during study days ]
  • Add'l pharmacokinetics - Terminal rate constant (λz); terminal half-life (t½λz), Apparent plasma clearance (CL/F), apparent volume of distribution during terminal phase (Vz/F), mean residence time (MRT). [ Time Frame: Frequent sampling occasions during study days ]
  • Pharmacodynamics - Plasma cortisol concentrations [ Time Frame: Frequent sampling occasions during study days ]

Estimated Enrollment: 72
