Conditions: Healthy Volunteer Study

Summary: this is a multipart phase 1 randomized, double blind and placebo controlled study to determine safety, tolerability and pharmacokinetics, of sco-120 in healthy male and postmenopausal female volunteers.

part a- approximately 76 (approximately 8 sequential cohorts of 8 subjects per cohort) part b- up to approximately, 32 healthy males or post-menopausal female subjects will be enrolled part c- approximately 32 healthy male or postmenopausal female subjects (4 sequential cohorts of 8 subjects) will be enrolled

subjects must have urine cotinine levels below those measured for smokers (\< 200 ng/ml) . exclusion criteria: subjects will be excluded from the study if they meet any of the following criteria: (all parts) 1. any major surgery, as determined by the investigator, within 4 weeks of imp administration; 2. blood transfusion within 4 weeks prior to imp administration; 3. inability to swallow oral medication; 4. inability to undergo venipuncture and/or tolerate venous access; 5. female on hormone replacement therapy, or having been on the same in the past 6 months; 6. active liver disease or history of liver disease (such as hepatitis) in the past 6 months which can have impact on study endpoints and/ safety of subjects as per investigator discretion; 7. medical history of thromboembolic disorders or with risks (such as hematologic or rheumatologic disorders); recent history of thrombophlebitis; 8. subjects with complaints of hot flashes at screening; 9. history of abnormal vaginal bleeding within 3 months prior to screening and/ or uterine malignancy 10. positive exclusion tests: human immunodeficiency virus (hiv), hepatitis b surface antigen, or hepatitis c virus; 11. history of any relevant allergy/hypersensitivity (including known immediate or delayed hypersensitivity reaction or idiosyncrasy to drugs chemically related to the imp or its excipients); 12. received another investigational agent within 30 days (or for investigational agents with long half life a washout of 5 half-lives will be required) prior to imp administration or intake of an investigational drug during the course of this study; 13. intake of any prescribed medication/drugs within at least 14 days and/or over-the-counter drugs within at least 7 days (or less than 5 half-lives of the respective drug) prior to administration of the imp; 14. known and/ or suspected history of significant drug abuse as judged by the investigator; 15. positive screen for drugs of abuse at screening visit or positive screen for alcohol or drugs of abuse on admission to the study centre prior to the first imp administration;

17. current or recent disease of the gastrointestinal tract that may impact drug absorption and may affect the pk of the imp, or any gastrointestinal tract surgery history that may impact drug absorption; 18. continued use of caffeine or grapefruit juice or xanthine-containing drinks or food, e.g., coffee, tea, chocolate, red bull, or cola for 48 hours prior to dosing and till the last pk sample collection; 19. any concomitant clinically significant disorder, like infection, diabetes etc. that would pose a risk to subject safety or interfere with the study evaluation, procedures, or completion which can have impact on study endpoints and/ safety of subjects as per pi discretion.
