Key inclusion criteria
Participants must meet all of the following criteria to be eligible for
participation in the study:

1. Males or females aged 45 years or over.

2. Female participants of non-childbearing potential, meeting at least one of the
following criteria:

- Amenorrhoeal for 12 months (menopause confirmed by Follicular Stimulating Hormone
(FSH) and Luteinising Hormone (LH) levels as defined by the established reference
ranges), or

- Surgically sterile (e.g. hysterectomy, oophorectomy, tubal ligation) for at least
the past 3 month.

3. Able to communicate with site personnel and to understand and voluntarily sign the
Informed Consent Form (ICF).

4. Able and willing to comply with the protocol, including availability for all scheduled
study visits.

5. Body mass index (BMI) 18 kg/m2 to 30 kg/m2 (inclusive)

6. No clinically significant abnormalities as determined by medical history, physical
examination, blood chemistry, hematology, urinalysis, and 12-lead electrocardiogram

7. If male, agrees to use a medically acceptable method of contraception from Screening
until 7 days after administration of the last dose of study drug. Medically acceptable
methods of contraception include the following: abstinence; medically approved
hormonal methods; condom; diaphragm; and intrauterine device. This requirement may be
waived if the Principal Investigator or delegate is satisfied that the participant or
partner is sterile (i.e., if female has undergone a hysterectomy, or has undergone a
tubal ligation at least 3 months prior to Screening, or is postmenopausal [no
menstrual period for at least 12 months prior to Screening]; if male, has undergone
vasectomy at least 6 months prior to Screening). Male participants agree not to donate
sperm for at least 90 days [3 months] after administration of the last dose of study

8. Agree to avoid drinking alcohol within 72 hours prior to check-in to the clinical

9. Adequate venous access in the left and right arm to allow collection of a number of
blood samples.
Minimum age
45 Years

Key exclusion criteria
Participants meeting any of the following criteria are ineligible for
participation in the study.

1. Evidence or history of clinical significant hematological, renal, endocrine,
pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurologic, or
allergic diseases

2. Orthostatic blood pressure changes (>15mmHg) or symptoms, or presence of uncontrolled
hypertension (SBP >160 mmHg or diastolic >95 mmHg) at screening, admission (Day -1) or
pre-dose (Day 1).

3. Greater than 2 standard drinks per day, on average, for men and women, or any history
of drug or alcohol addiction or abuse within the last 5 years.

4. History of allergic, anaphylaxis or hypersensitivity to OTS167 or excipients or
contents of Humco ™ cherry syrup.

5. Female participants who are currently lactating.

6. Donated either blood or plasma (e.g., plasmapheresis) within 6 weeks prior to dosing
in Period 1. All participants must be advised not to donate either blood or plasma for
at least 6 weeks after completing the study.

7. Use of prescription medications (with the exception of contraceptives),
over-the-counter medications (with the exception of paracetamol [< 2 gm/day] or
single-dose daily multivitamins), or herbal medications or products containing herbal
extracts within 14 days prior to the first dose.

8. Positive results on illicit drug test or alcohol breath test at screening or at

9. Positive screening test for HIV antibodies, Hepatitis B surface antigen or Hepatitis C

10. Use of any investigational drug within the last 30 days or within a period of 5 times
the drug's half-life, whichever is longer, or current participation in any
investigational protocol.

11. Participants who, in the opinion of the Principal Investigator or delegate, should not
participate in the study or are not capable of following the study schedule for any

12. Either QTcF >450 or HR <40 or >100 at screening, admission (Day-1) or pre-dose (Day
1). Test may be repeated at discretion of investigator to obtain average in order to
confirm eligibility.

Brief summary
The purpose of this study is to determine the indicative bioavailability of a single oral
dose of OTS167, and to evaluate the effects of food on OTS167 pharmacokinetics (PK) after
oral dosing.

Eleven male and female healthy participants aged 45 years and over will be entered into this
phase 1, single-centre, double-blind, randomised, cross-over study. The trial is designed to
evaluate the bioavailability of OTS167, and the effects of food on pharmacokinetics (PK) of
OTS167 when administered by the oral route. Correlative studies include evaluation of safety
endpoints and examinations, and adverse events. This study involves 3 cohorts to evaluate the
safety and tolerability of oral dosing from lower dose.
