Eligibility
Key inclusion criteria
Inclusion Criteria

- Participants must be medically healthy based on medical history, physical examination,
and clinical laboratory testing.

- Participants must be between 18 to 54 years of age, inclusive at the time of the
informed consent.

- May only be limited users of nicotine-containing products, including e-cigarettes, for
at least 3 continuous months before the first dose of SON-1010, as confirmed by
cotinine testing at screening and check-in (day -1). Social smoking is allowed up to 5
cigarettes per week as long as the participant is willing to abstain during
confinement and the cotinine test is negative at check in. One repeat test is
permitted at screening.

- Must have negative drug/alcohol testing at screening and check-in (day -1). Screening
drug/alcohol testing may be repeated once if deemed appropriate.

- Must have vital signs (after sitting for at least 5 minutes) within the following
ranges at screening and check-in (day -1):

- Systolic blood pressure (BP), 90 to 140 mmHg, inclusive

- Diastolic BP, 40 to 90 mmHg, inclusive

- Heart rate (HR) >50 to =100 beats per minute

- Must weigh >50 kg and =100 kg and have body mass index (BMI) =18 and =32 kg/m2 at
screening.

- Must have normal laboratory function by day -1 (note that the screening safety
laboratory assessment may be repeated once to confirm the initial result and
trending), defined as:

- Creatinine level = upper limit of normal (ULN) for age

- Alanine aminotransferase (ALT) = ULN

- Total bilirubin = ULN (unless participant has Grade 1 bilirubin elevation due to
Gilbert's disease or a similar syndrome involving slow conjugation of bilirubin
and direct bilirubin is <35%)

- Albumin > lower limit of normal (LLN)

- Coagulation International Normalized Ratio (INR) < 1.5

- Females of childbearing potential, <1-year postmenopause who are not permanently
sterile, must have a negative serum pregnancy test (beta-human chorionic gonadotropin
[ß-HCG]) at day -1, and agree to abstinence or use 2 highly effective methods of birth
control for 30 days before the study, during the study, and for 30 days after the last
dose of study intervention. Females who are not of childbearing potential (have had a
hysterectomy, bilateral oophorectomy, or are = 1-year postmenopause) do not need to
use any contraception Nonchildbearing potential is defined as surgically sterile or
postmenopausal (defined as 12 months of spontaneous amenorrhea). A follicle
stimulating hormone (FSH) level >40 IU/L at screening will confirm postmenopausal
status. If a participant is not sexually active, but becomes active, then she and her
male partner must use 2 methods of adequate contraception.

- Males and their female partners must use a highly effective method of birth control if
female partner(s) is of childbearing potential and must not donate sperm during the
study and for 90 days after the last dose of study intervention. Contraception
guidance is described in the protocol.

- Willing and able to provide signed informed consent as described in the protocol which
includes compliance with the requirements and restrictions listed in the informed
consent form (ICF) and in this protocol.

- Must be able to communicate well with Investigator and/or study site personnel and to
comply with the requirements of the entire study.

- History of severe allergic/anaphylactic reaction.

- Receipt of any plasma-, protein-, or antibody-based therapeutic agents (e.g., growth
hormones or monoclonal antibodies) within 3 months before the first dose of study
intervention. Note: Influenza and COVID-19 vaccines will be allowed if administered
more than 14 days before the first dose of study intervention.

- Receipt of any investigational agent or treatment within 30 days or 5 half-lives,
whichever is longer, before the first dose of study intervention.

- Any active infection, including COVID-19, as determined by the currently applicable
standard before study intervention.

- Any acute noninfectious illness within 30 days before day 1.

- Diagnosis of or positive screening result for active COVID-19, hepatitis B surface
antigen (HbsAg), hepatitis C virus antibody (HCVAb), or human immunodeficiency virus
(HIV)-1 or HIV-2 antibody.

- Unable or unwilling to cooperate with the Investigator for any reason.

- History of any clinically relevant or chronic psychiatric, renal, hepatic,
cardiovascular, pancreatic, neurologic, hematologic, or gastrointestinal disease
(e.g., inflammatory bowel disease) or current clinically significant liver function
test results. Mild anxiety and depression may be acceptable at the investigator's
discretion.

- Evidence of any surgical or medical condition that, in the judgment of the
Investigator, might interfere with the absorption, distribution, metabolism, or
excretion of study intervention. History of cholecystectomy is acceptable.

- Presence of clinically significant electrocardiogram (ECG) finding (confirmed upon
repeat testing) that may interfere with any aspect of study conduct or interpretation
of results, as follows:

- QT interval corrected for HR according to Fridericia's formula (QTcF) > 450 in
males or > 470 msec in females at screening or check-in (day -1).

- Other ECG abnormalities clinically relevant in the judgment of the Investigator.

- Use of any prescription or over-the-counter medications (apart from standard doses of
analgesics), herbal products (e.g., St. John's Wort, garlic supplements, milk
thistle), topical or inhaled steroids, or supplements/vitamins within 7 days before
the first dose of SON-1010 and for the duration of the study, except for those
approved by the Investigator and Sponsor (e.g., oral contraceptives, hormone
replacement therapy).

- Recent use of systemic steroids within 14 days of enrollment, except for physiologic
doses for steroid replacement. Limited doses of systemic steroids (e.g., in patients
with exacerbation of reactive airway disease) must have been completed at least 10
days before enrollment.

- Use of biotin (i.e. Vitamin B7) or supplemental biotin higher than the daily adequate
intake of 30 µg (FDA 2019). Patients who switch from a high dose to a dose of 30
µg/day or less are eligible.

- History of alcohol or substance abuse within 6 months before the first dose of
SON-1010 per the criteria in the Diagnostic and Statistical Manual of Mental
Disorders, Fifth Edition (DSM-V).

- History of any major surgery within 3 months before the first dose of study
intervention.

- Donation or receipt of blood or blood product within 3 months before the first dose of
SON-1010 and for the duration of the study.
