Eligibility
Key inclusion criteria
1. Volunteers aged 50 to 75 years.

2. Female subjects:

1. Post-menopausal women, defined as no menses for 12 months without an alternative
medical cause. If there is any concern about the menopausal status of a
prospective female subject, a follicle stimulating hormone test (FSH) should be
requested to confirm post-menopausal status. Post-menopausal women confirmed by
FSH level > 40 mIU/mL, will be confirmed by the local laboratory.

2. Women of childbearing potential (WOCBP) must have a negative pregnancy test.

3. Male Subjects:

1. Who are sexually active, fertile men must use highly effective methods of
contraception from Day 1 until 3 months after last dose of study drug if their
partners are WOCBP

2. Who are permanently sterile or have had bilateral orchiectomy or bilateral
vasectomy.

4. No disease which may cause a peripheral neuropathy.

5. No evidence of alcohol abuse (defined as greater than 21 standard units per week for
males and greater than 14 standard units per week for females).

6. Must provide written informed consent to participate in the study and be willing and
able to participate for the maximum of 12 weeks of treatment and 16 weeks of site
visits.
Minimum age
50 Years
Maximum age
75 Years
Sex
Both males and females
Can healthy volunteers participate?
Yes
Key exclusion criteria
1. Clinically significant abnormalities in vital signs (blood pressure, heart rate,
respiration rate and oral temperature), as determined by the investigator.

2. Body Mass Index (BMI) > 38 kg/m2

3. Clinically significant abnormal haematology, biochemistry and urine examination
values, as determined by the investigator.

4. Participants who have a history of liver disease, including fatty liver, or LFT
elevations requiring investigation will not be eligible.

5. Has had a significant systemic illness or infection within the past 4 weeks prior to
randomisation, as determined by the investigator.

6. Documented diagnosis of Type I or Type II diabetes.

7. Has a history of disease directly related to the hypothalamus, the pituitary and/or
the adrenal glands which affects the hypothalamic-pituitary-adrenal axis function.

8. Has any uncontrolled clinical condition relating to glucose or lipid metabolism.

9. Subjects with clinical evidence of peripheral neuropathy or historical evidence of
clinically significant nerve conduction abnormalities. Clinical evidence of
neuropathy.

10. Clinically significant electrocardiogram (ECG) abnormalities, including QTc interval >
450 msec (male) and > 470 msec (female), following ECG tracings at Screening.

11. Use of any prohibited medication.

investigational drug/device administration is within 60 days of Screening.

13. Inability to communicate well with the investigator (i.e. language problem, non-fluent
English [as questionnaires and study drug label will be provided in English only],
poor mental development or impaired cerebral function).

14. Subject will undergo the Columbia Suicide Severity Rating Scale (CSSRS), Toronto
Clinical Neuropathy Score (TCNS), EuroQoL Health Related Quality of Life - 5
Dimensions - 5 Levels (EQ-5D-5L), and Cogstate Test Battery at the indicated
time-points to avoid uncontrolled learning effects. Subjects who need to perform these
tests externally to and in parallel with this study will be excluded.

15. For subjects that consent, and are subsequently accepted for enrolled into, the CSF
optional sub-study, subjects must have no contraindications to the lumbar puncture
procedure as assessed by the Principal Investigator. Such contraindications may
include uncontrolled bleeding abnormalities or skin or spine abnormalities.

16. Positive testing for human immunodeficiency virus (HIV), hepatitis B surface antigen
(HBsAg), or hepatitis C antibodies (HCV). Subjects returning a positive result will be
managed by the site in line with standard care.

Summary
Brief summary
Xanamem™ is being developed as a potential drug for Alzheimer's disease. This study drug has
been designed to change the cortisol levels in the brain. Cortisol is a naturally occurring
hormone in the body. It is believed that reducing the level of cortisol will be a benefit in
the treatment of Alzheimer's disease.

The XanaHES study is testing the safety and tolerability of Xanamem. It is planned to enrol
approximately 84 participants, male and female aged from 50 to 75 who are in good health, in
the study at 1 centre in Australia.

The XanaHES Phase I study is a single-blind study. Subjects will be randomised to receive
either 20mg once daily Xanamem or Placebo in cohort 1. Once all subjects have completed the
study treatment of 12 weeks, a dose escalation committee will decide if a new cohort, cohort
2, with 30mg once daily vs placebo is started.
