Key inclusion criteria
- Male or female 18 to 50 years of age, inclusive, at the time of screening

- Able to understand the requirements of the study, to provide written informed consent
(as evidenced by signature on an informed consent document that is approved by a Human
Research Ethics Committee [HREC]), and agreeable to abide by the study restrictions

- Body mass index (BMI) of 18.0 to 35.0 kg/m^2, inclusive, at the time of screening

- Weight between 50 kg and 110 kg, inclusive, at the time of screening and check-in (Day

- Good general health (e.g., no chronic health conditions such as hypertension,
diabetes, chronic obstructive pulmonary disease, or cardiovascular disease) as
determined by the Investigator; participants with mild allergies or benign conditions
such as Gilbert's disease may be enrolled at the discretion of the Investigator

- Female participants of child-bearing potential, with a fertile male sexual partner,
must use a highly effective method of contraception (oral contraceptive, intrauterine
device, or hormonal patch, injectable, or implantable device) in conjunction with a
male condom during the screening period and for the entire duration of study
participation including the 28-day follow-up; true abstinence from sexual intercourse
with a partner of the opposite sex, in accordance with the preferred and usual
lifestyle of the participant, is acceptable; periodic abstinence or avoiding sexual
intercourse on days while the participant is fertile (calendar, symptothermal,
post-ovulation methods), withdrawal (coitus interruptus), are not acceptable methods
of contraception; non-childbearing potential is defined as postmenopausal as
documented by an elevated follicle stimulating hormone (FSH) level or surgical
sterility (e.g., tubal ligation, hysterectomy, and/or bilateral salpingo-oophorectomy)

- Male participants must either be surgically sterile (vasectomy) or agree to use a male
condom as a method of contraception for the entire duration of the study and for 90
days after dosing; the female sexual partner must also use a medically acceptable form
of birth control (e.g., oral contraceptive)

- Male participants must agree to not donate sperm for the entire duration of the study
and for at least 90 days after dosing
