the participant);

- If male, participant agrees to abstain from sperm donation from initial study drug
administration through 90 days after administration of the last dose of study drug;

- Body Mass Index (BMI) is = 18.0 to = 31.0 kg/m2, inclusive;

- A condition of general good health, based upon the results of a medical history,
physical examination, vital signs, laboratory profile, and a 12-lead electrocardiogram
(ECG), as judged by the investigator;

- Must voluntarily sign and date each informed consent, approved by a Human Research
Ethics Committee (HREC), prior to the initiation of any screening or study-specific
procedures.

Key exclusion criteria
- History of clinically significant drug allergies, including allergies to any of the
components of the investigational product and/or clinically significant food allergies
as determined by the investigator;

- Presence or history of any significant cardiovascular, gastrointestinal, hepatic,
renal, pulmonary, hematologic, endocrine, immunologic, dermatologic, neurologic, or
psychiatric disease, as determined by the investigator;

herbal supplements on an ongoing basis;

- Use of any OTC medications (over-the-counter), including herbal products, within 7
days prior to Day 1, other than limited paracetamol use (= 2 g/day) or oral
contraceptive pill. Use of any prescription medication within 14 days or 5 half-lives
(whichever is longer), prior to study drug administration, unless in the opinion of
the Principal Investigator and/or Medical Monitor the medication will not compromise
participant safety or interfere with study procedures or data validity;

- Recent (6-month) history of drug or alcohol abuse;

- Positive test result for hepatitis B surface antigen (HBsAg), hepatitis C virus
antibody (HCV Ab), or HIV antibodies (HIV Ab) at screening;

- Donation or loss of 550 mL or more blood volume (including plasmapheresis) or receipt
of a transfusion of any blood product within 8 weeks prior to study drug
administration;

- Receipt of any investigational product within a time period equal to 10 half-lives of
the product, if known, or a minimum of 30 days prior to study drug administration;

- Positive screen results for drugs of abuse, alcohol, or cotinine at screening or Day
-1;

- Consumption of alcohol within 72 hours prior to study drug administration;

- Consumption of grapefruit, grapefruit products, star fruit, star fruit products, or
Seville oranges within the 72-hour period prior to study drug administration;

- Use of tobacco or nicotine-containing products within the 6-month period preceding
study drug administration;

- Current enrollment in another clinical study;

- Screening laboratory analyses that show any of the following abnormal laboratory
results:

- Alanine transaminase (ALT) level above 1.5 times the upper limit of normal (ULN);

- Aspartate transaminase (AST) level above 1.5 times the ULN;

- Any other laboratory results that are outside of the laboratory normal reference range
and considered clinically significant by the investigator;

- Clinically-significant abnormal ECG; ECG with QTc using Fridericia's correction
formula (QTcF) > 450 msec (for males) or >460 msec (for females) is exclusionary;

- Consideration by the investigator, for any reason, that the participant is an
unsuitable candidate to receive RTA 1701.

Summary
Brief summary
This first-in-human, Phase 1, single-center study will evaluate single ascending doses (SAD)
and multiple ascending doses (MAD) of RTA 1701 conducted in 2 parts. Part 1 (SAD) of this
study will be conducted in approximately 56 healthy participants in up to 7 groups. Each
group will consist of up to 8 participants who will be randomized in a 3:1 ratio to receive a
single dose of RTA 1701 or placebo, respectively. Safety, tolerability, and available
pharmacokinetics in each group will be assessed by the Safety Monitoring Committee prior to
dose escalation.

Part 2 (MAD) of this study will be conducted in approximately 30 healthy participants in up
to 3 groups and will commence after safety data for the highest dose in the SAD phase has
been evaluated. Each group will consist of up to 10 participants who will be randomized in a
4:1 ratio to receive 14 daily doses of RTA 1701 or placebo, respectively. Safety,
tolerability, and available pharmacokinetics will be assessed in each dosing group prior to
dose escalation
