About this study

This study will be a Phase 1, randomized, single-blind, placebo-controlled, single and multiple ascending dose sequential group design in up to 48 healthy male Japanese subjects, performed at a single study center. The planned number of cohorts is 4 but up to 6 cohorts may be included if the Safety Review Committee (SRC) considers it necessary to repeat a dose level or if additional dose steps are required. Screening will be completed between Days -28 and -1. Primarily gradual escalation of the dose will be conducted with the oral suspension. Eight subjects will participate in each cohort. Four ascending dose levels are planned. Within each cohort 6 subjects will be randomised to receive AZD5718 and 2 subjects randomised to receive placebo. Each subject will receive one dose of AZD5718 or placebo on the first dosing day (Day 1, single ascending dose, SAD) and on Days 3 to 10 (multiple ascending dose, MAD). On Day 2 no dose will be given to the subject. In total each subject will receive 9 doses. Dosing for each ascending dose cohort will proceed after the SRC has evaluated the safety, tolerability and other relevant data of a completed cohort. The subjects will stay at the study site until 48 hours post-dose and will return 7 to 10 days after dosing for a follow-up visit. Each subject will be involved in the study for 7 weeks.

  13. Plasma PK assessment: Observed average concentration (Cavg) assessment for AZD5817 after single and repeated oral dosing (Day 10)

    Time frame: Day 10: pre-dose, 0.5, 1, 2, 3, 4, 6, 8, 12, 16, 24, 32 and 48 hours (Day 3 pre-dose) post-dose

    To assess Cavg of AZD5718 after single and repeated oral dosing. Cavg will be taken directly from the individual concentration-time curve.

  14. Plasma PK assessment: Accumulation ratio (Rac Cmax) assessment for AZD5817 after single and repeated oral dosing

    Time frame: Day 1 and Day 10: pre-dose, 0.5, 1, 2, 3, 4, 6, 8, 12, 16, 24, 32 and 48 hours (Day 3 pre-dose) post-dose

    To assess Rac Cmax of AZD5718 after single and repeated oral dosing. Rac Cmax will be calculated as Cmax Day 10/ Cmax Day 1.

  15. Plasma PK assessment: Accumulation ratio (Rac AUC) assessment for AZD5817 after single and repeated oral dosing

    Time frame: Day 1 and Day 10: pre-dose, 0.5, 1, 2, 3, 4, 6, 8, 12, 16, 24, 32 and 48 hours (Day 3 pre-dose) post-dose

    To assess Rac AUC of AZD5718 after single and repeated oral dosing. Rac AUC will be calculated as AUCτ Day 10/ AUCτ Day 1.

  16. Plasma PK assessment: Temporal change parameter in systemic exposure (TCP) assessment for AZD5817 after single and repeated oral dosing

    Time frame: Day 1 and Day 10: pre-dose, 0.5, 1, 2, 3, 4, 6, 8, 12, 16, 24, 32 and 48 hours (Day 3 pre-dose) post-dose, Day 4-9 pre morning dose

    To assess TCP of AZD5718 after single and repeated oral dosing. TCP will be calculated as AUCτDay 10/AUCDay 1.

  17. Urine PK assessment: Cumulative amount of unchanged drug excreted in urine from time zero to the last sampling interval (Ae(0-last)) assessment for AZD5817 after single and repeated oral dosing

    Time frame: Day 10 pooled 0-3, 3-6, 6-9, 9-12 hours and 12-24 hours urine

    To assess Ae(0-last) of AZD5718 after single and repeated oral dosing.

  18. Urine PK assessment: Fraction of dose excreted unchanged into the urine from time zero to the last sampling interval measured time point for an analyte (Fe(0-last)) assessment for AZD5817 after single and repeated oral dosing

    Time frame: Day 10 pooled 0-3, 3-6, 6-9, 9-12 hours and 12-24 hours urine

    To assess Fe(0-last) of AZD5718 after single and repeated oral dosing. Fe(0-last) will be estimated by dividing Ae(0-last) by dose.

  19. Urine PK assessment: Renal clearance of drug from plasma (CLR) assessment for AZD5817 after single and repeated oral dosing

    Time frame: Day 10 pooled 0-3, 3-6, 6-9, 9-12 hours and 12-24 hours urine

    To assess CLR of AZD5718 after single and repeated oral dosing. CLR will be estimated by dividing Ae(0-last) by AUC(0-t)).

  20. PD parameter: urine Leukotriene E4 (LTE4) assessment for AZD5817 after single and repeated oral dosing

    Time frame: Day -1 (spot sample), Day 1 and Day 10 spot sample pre-dose and pooled 0-3, 3-6, 6-9 and 9-12 hours urine, spot sample at 24, 36 hours post-dose, Day 3-9: spot sample pre-dose

    To evaluate the PD of AZD5718, by assessment of urine LTE4 (u-LTE4), after single and repeated oral dosing.
