Eligibility
Key inclusion criteria
Key inclusion criteria:

1. Must have given written informed consent before any study-related activities are
carried out and must be able to understand the full nature and purpose of the trial,
including possible risks and adverse effects.

2. Healthy adult male or female, or adult male or female with a stable chronic disease or
condition aged 50-85 years of age, inclusive. Adults with stable chronic disease or
condition includes adults with no new diagnosis, hospitalisation or changes in
medication in the 3 months prior to first dose of study drug on Day 1. Ongoing
concomitant medications associated with the stable disease or condition, including
over-the-counter (OTC) medications and herbal/vitamin supplements taken by volunteers,
will be recorded and reviewed by the PI (or delegate) to determine whether the
volunteer is suitable for inclusion in the study. In conducting this review, the PI
(or delegate) must consider
Minimum age
50 Years
Maximum age
85 Years
Sex
Both males and females
Can healthy volunteers participate?
Yes
Key exclusion criteria
Exclusion Criteria 11, 12, 13 and 14.

3. The volunteer is considered by the Investigator to be in stable health

Key exclusion criteria :

1. Presence of CS cardiovascular, pulmonary, hepatic, renal, haematologic,
gastrointestinal, endocrine, immunologic, dermatologic, neurologic, oncologic, or
psychiatric disease, or any other condition that, in the opinion of the Investigator,
would jeopardise the safety of the participant or the validity of the study results.

2. Had a CS new illness within 1 month prior to the screening visit, with the exception
of fully resolved gastrointestinal illness at least 14 days prior to the screening
visit, fully resolved minor colds (e.g., only cold and flu-like symptoms) that
occurred within 1 month prior to the screening visit, and fully resolved corona virus
disease 2019 (COVID-19) infections if resolved at least 14 days prior to the screening
visit and 30 days prior to confinement to the clinical facility.

3. A history of uncontrolled hypertension, coronary artery disease, or any other
significant cardiovascular disease.

4. A history of uncontrolled diabetes. Volunteers with fully resolved gestational
diabetes will be eligible to participate in the study.

5. A history of unexplained loss of consciousness, epilepsy or other seizure disorder, or
cerebrovascular disease.

Summary
Brief summary
This is a Phase 1b, parallel single-dose study to evaluate the pharmacokinetics (PK) and
pharmacodynamics (PD) of Tinlarebant when administered as an oral dose to elderly healthy
volunteers. This study will evaluate 2 dose levels in 2 cohorts comprising up to a total of
16 participants (8 per cohort). Dose levels will be evaluated in parallel.
