Detailed Description

This study will be a phase I study to assess the pharmacodynamics of AZD9977 following single-dose administration to healthy male subjects. It is a single-blind (with regards to AZD9977 and AZD9977 Placebo), randomized, four-treatment, four-period crossover design, with a potential 5th and 6th randomized cross-over treatment period. In this study eplerenone is used as a positive control and fludrocortisone will be used as a challenge agent. In addition the safety, tolerability and pharmacokinetics will be assessed.

A 12-lead ECG was obtained after each subject had rested in the supine position for at least 10 minutes and was performed in accordance with the Schedule of Assessments of study protocol. The investigator judged the overall interpretation as normal or abnormal. If abnormal, it would have been decided as to whether or not the abnormality was clinically significant and the reason for the abnormality would have been recorded. The investigator could add extra 12-lead resting ECG safety assessments if there were any abnormal findings of if the investigator considered it was necessary for any other safety reason. These assessments would have been entered as an unscheduled assessment.

  19. Number of Participants With Clinically Significant Physical Examination Values. [From screening to post-study visit, up to 10 weeks]

The brief physical examinations included an assessment of the general appearance, skin, abdomen, cardiovascular and respiratory systems. The results of the physical examination were listed by body system for each subject. Body weight was listed by participant and time-point. Any new or aggravated clinically relevant abnormal medical finding at a physical examination as compared with the baseline assessment were reported as an adverse event (AE).

If deterioration in laboratory value was associated with clinical symptoms and/or signs, the symptom or sign were reported as an adverse event and the associated laboratory result was considered as additional information. Laboratory results were listed and summarized according to change from baseline and repeat/unscheduled measurements. Any out of range laboratory results were flagged in the individual listings.

The investigator judged the overall interpretation as normal or abnormal. If abnormal, it would have been decided as to whether or not the abnormality was clinically significant and the reason for the abnormality would have been recorded. The investigator could add extra 12-lead resting ECG safety assessments if there were any abnormal findings of if the investigator considered it was necessary for any other safety reason.

Description Pharmacodynamics of AZD9977 assessed per fractional potassium excretion in urine for each urine collection time interval. Pharmacodynamics of AZD9977 after single dosing of AZD9977 with fludrocortisone and/or eplerenone
Time Frame From 0 to 8 hours post dosing

Outcome Measure Data

Analysis Population Description
The PD analysis set consisted of all participants in the SAF with at least one evaluable sum of the logarithm of the sodium/potassium ratio from two hours up to eight hours post dose, and who had no major protocol deviations thought to impact on the analysis of the PD data.
