Arm && Interventions

Group	Intervention	Description
Placebo to match AZD8848	Placebo to match AZD8848	Subjects will participate in 1 of 3 groups and receive multiple doses of AZD8848 or matching placebo. In each group 6 subjects will receive AZD8848 and 2 subjects will receive matching placebo.
AZD8848	AZD8848	Subjects will participate in 1 of 3 groups and receive multiple doses of AZD8848 or matching placebo In each group 6 subjects will receive AZD8848 and 2 subjects will receive matching placebo.

Primary Outcome Measures

Name	Time	Method
Change from baseline up to 77 days in safety variables (adverse events, vital signs, body temperature, physical exams, ECGs, clinical laboratory tests, pulse oximetry, spirometry).	From screening visit (Day -42) through the Treatment Follow Up visit (Day 35) at multiple timepoints up to 77 days.

Secondary Outcome Measures

Name	Time	Method
Multiple dose pharmacokinetics profile for AZD8848 and its acid metabolite (AZ12432045) combined and, if possible, for AZD8848 alone in plasma	Plasma: From Days 1 and 22, pre-dose, 5, 10, 20, 30, 45, 60, 90 min, 2, 3, 4, 6, 8 and 24 hrs post dose	PK parameters: AUC accumulation ratio and Cmax accumulation ratio
Single dose pharmacokinetics profile for AZD8848 and its acid metabolite (AZ12432045) combined and, if possible, for AZD8848 alone in plasma and urine from healthy subjects	Plasma: From Days 1 and 22, pre-dose, 5, 10, 20, 30, 45, 60, 90 min, 2, 3, 4, 6, 8 and 24 hrs post dose. Urine: From days 1 and 22, pre-dose, 0 to 6, 6 to 12 and 12 to 24 hrs post dose	PK parameters: Cmax, tmax, area under the plasma concentration-time curve from zero to 24 hours postdose (AUC(0-24)), from zero to the time of the last quantifiable concentration (AUC(0-t)) and from zero to infinity (AUC), CL/F, Vz/F, CLR and Ae
Pharmacodynamic effect after multiple doses of inhaled AZD8848 by assessment of the CXCL10 biomarker concentration in plasma	From Days 1 and 22, pre-dose, 24 and 48 hrs post dose. One sample 7 to 13 days post last dose.	Pharmacodynamic effect: CXCL10 concentration and change-from-baseline ratios in plasma
