Primary Purpose: Basic Science
Official Title: A Phase I, Single Centre, Double-blind, Randomised, Placebo-controlled, Parallel-group Study to Assess the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics After Single and Multiple Ascending Inhaled Doses of AZD7594 in Healthy Male Volunteers

Further study details as provided by AstraZeneca:

Primary Outcome Measures:
  • Safety profile in terms of adverse events, ECG, blood pressure, pulse, physical examination, body temperature, haematology, clinical chemistry, urinalysis and spirometry. [ Time Frame: Screening to 13 days post last dose. ]
    No statistical tests will be performed


Secondary Outcome Measures:
  • Single dose pharmacokinetics (PK) of AZD7594 in terms of : Cmax, tmax, λz, t1/2λz, AUC(0-last), AUC(0-24), AUC, CL/F, Vz/F, MRT, Cmax/D, AUC/D, AUC(0-24)/D. [ Time Frame: pre-dose and at 5, 15 and 30 minutes and 1, 2, 4, 6, 9, 12, 18, 24, 36 and 48 hours post-dose. From cohort four 72 and 96 hours post-dose samples will also be taken. ]
    Cmax- max plasma concentration;tmax-Time to max plasma concentration,λz- terminal rate constant;t1/2λz - Terminal half-life;AUC(0-24) - Area under the plasma concentration time curve from zero to 24 hours;AUC- Area under the plasma concentration

  • Multiple dose PK of AZD7594 in terms of: Cmax, tmax, λz, t1λz, AUC(0-last), AUC(0-24), AUC, CL/F, Vz/F, MRT, Cmax/D, AUC/D,AUC(0-24)/D, Cavg, %Fluctuation, Rac(Cmax) and Rac(AUC(0-24) and time-dependency (AUC(0-24) and AUC) [ Time Frame: pre-dose and at 5, 15 and 30 min and 1, 2, 4, 6, 9, 12, 18, 24, 48, 72 hours and 96 h post-dose. Days 6-15: Pre-dose samples only.From day 16: pre-dose and 5, 15 and 30 min and 1, 2, 4, 6, 9, 12, 18, 24, 36 and 48 h post-dose. ]
    CL/F- Apparent plasma clearance;Vz/F- Apparent volume of distribution during terminal phase; MRT- Mean residence time; Rac Cmax-Accumulation ratio of Cmax

  • Pharmacodynamics of AZD7594 following a single dose in terms of: 24-hour plasma cortisol [ Time Frame: screening and on the dosing day at the following time points 0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24. On the dosing day also at 36 and 48 hours post dose. ]
  • Pharmacodynamics of AZD7594 following a multiple doses in terms of: 24-hour plasma cortisol [ Time Frame: screening and days 1 and 16 at the following time points 0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22 and 24 hours. On day 1 also at 36 and 48 hours. ]
  • Pharmacodynamics of AZD7594 following multiple doses in terms of: Plasma cortisol after adrenocorticotropic hormone stimulation [ Time Frame: screening and day 17 at 30 minutes and 1 hour post tetracosactide injection ]
  • Pharmacodynamics of AZD7594 following multiple doses in terms of: Plasma dehydroepiandrosterone sulphate, plasma 4β-OH-cholesterol, and plasma osteocalcin [ Time Frame: screening and day 17 ]
