• Postmenopausal, as defined as at least 1 year post-cessation of menses (without an alternative medical cause), and per documentation provided by a medical professional;

• Postmenopausal status will be confirmed with a screening serum follicle stimulating hormone (FSH) level greater than 40 milli-international units per milliliter (mlU/mL).

• Patient has a negative urine and/or serum pregnancy test (serum β-human chorionic gonadotropin) within 1 day prior to study entry, and agrees to use highly effective contraception methods during treatment and for at least 7 days after the last dose of i.v. study therapy;

3. Have a body mass index (BMI) between 18 and 32 kg/m2.

4. As judged by the Investigator, all the subjects must be able to understand and be willing to comply with study procedures, restrictions and requirements.

4.2 Exclusion criteria

Subjects should not enter the study if any of the following exclusion criteria are fulfilled:

1. Male subjects who do not agree to follow contraception restrictions.

2. Female subjects who are pregnant or currently lactating

3. Female subjects who are of child bearing potential who do not agree to follow contraception restrictions as detailed in section 5.1.10.

4. Donated blood in the 3 months prior to screening, plasma in the 7 days prior to screening, platelets in the 6 weeks prior to screening

6. Unwilling to abstain from vigorous exercise for 48 hours prior to any study visit

7. Unwilling to abstain from alcohol for 48 hours prior to any study visit

9. Received any medication, including St John's Wort, known to chronically alter drug absorption or elimination within 30 days prior to first dose administration unless in the opinion of the investigator it will not interfere with study procedures or compromise safety

10. Received any prescribed systemic or topical medication within 14 days prior to the first dose administration (with the exception of the oral contraceptive pill)

11. Received any non-prescribed systemic or topical medication, herbal remedy or vitamin / mineral supplementation within 14 days prior to the first dose administration (with the exception of paracetamol).

12. Subjects who have any abnormality of vital signs prior to the first dose administration that, in the opinion of the investigator, would increase the risk of participating in the study

13. Subjects who have any clinically significant abnormal physical examination finding

14. Subjects who have any clinically significant 12 lead ECG abnormality that, in the opinion of the investigator, would increase the risk of participating in the study

15. Subjects who have, or have any history of, any clinically significant cardiovascular, respiratory, gastrointestinal, neurological, psychiatric, metabolic, endocrine, renal, hepatic, haematological or other major disorder as determined by the investigator

16. Subjects who have any significant condition that may preclude nasal or oral intubation with a bronchoscope as determined by the investigator

17. Subjects who have any clinically significant allergy or allergic condition as determined by the investigator (with the exception of non-active hay fever)

18. Subjects who have had previous adverse reactions to benzodiazepines or anaesthetic agents (lidocaine or xylocaine) including reversal agents such as flumazenil

19. Subjects who have any clinically significant abnormal laboratory safety results as determined by the investigator with specific exclusions of any aspartate aminotransferase (AST) or alanine aminotransferase (ALT)upper limit of normal greater than or equal to 1.5 times upper limit of normal (ULN) at screening or day -1; total bilirubin > ULN (Gilbert's syndrome is acceptable), haemoglobin <12.0 g/dL or prothrombin time > 13 seconds (one repeat assessment is acceptable at screening)

20. Subjects who have hepatitis B or C or are carriers of HBsAg or are carriers of hepatitis C virus (HCV= Ab or are positive for HIV 1/2 antibodies.

21. Subjects who have a positive alcohol breath test or a positive urine drug screen ( a repeat assessment is acceptable)

22. Subjects who are still participating in another clinical study or who have participated in a clinical study involving administration of an investigational product in the 3 months (or 5 half-lives, whichever is longer) prior to first dose administration

23. Subjects who, in the opinion of the investigator, should not participate in this study For procedures for withdrawal of incorrectly enrolled subjects, see Section 5.3. Subjects who drop out will be replaced.
