Brief summary: This study is designed to assess the safety and PK/PD of GTB and Benzoic Acid (Benzoate) using a single ascending dose (SAD) study (under fasting conditions).

Detailed description: This study is designed to assess the safety and PK/PD of GTB and Benzoic Acid (Benzoate) using a single ascending dose (SAD) study (under fasting conditions). After a wash out period, a cohort under fed conditions (ingestion of a high-fat morning meal) will be evaluated. Following the SAD, the multiple ascending dose phase will take place with two different cohorts. A battery of labs, hematology, physical examinations including vital signs, and ECGs will be monitored throughout the study for assessment of the study drug (GTB) compared with placebo. The clinical and laboratory data (excluding PK/PD data) of each cohort will be evaluated by a Data Monitoring Committee (DMC) to allow escalation to the next dose level during the SAD and MAD portions of the study.

Eligibility criteria: Inclusion Criteria:

1. Signed informed consent prior to any study-related procedures.
2. Male or female subjects 18 to 50 years of age inclusive.
3. Subject's body mass index (BMI) is ≥ 18 kg/m2 and ≤ 30 kg/m2.
4. Female subjects of childbearing potential must not be pregnant or lactating with a negative serum human chorionic gonadotropin (HCG) pregnancy test result at Screening, and negative urine pregnancy test on Day -1 (including Day -1 of Period 2 for SAD dosing participants i.e., fed cohort).
5. Female subjects of childbearing potential must use an adequate method of contraception from Screening until 30 days after last dose of study medication. Acceptable methods of contraception are barrier methods (female condom, diaphragm, cervical cap, spermicide, or intrauterine device \[IUD\]), surgical sterility (self-reported: tubal ligation, hysterectomy, and/or bilateral oophorectomy), oral hormonal contraceptives, hormonal IUD, and/or postmenopausal status (defined as at least 1 year without menses as demonstrated by medical history or subject report).
6. Male subjects must use an adequate method of contraception from Screening until 30 days after last dose of study medication. Acceptable methods of contraception are barrier methods (condom), surgical sterility (self-reported), must also refrain from donating sperm while on study medication and until 30 days after last dose of study medication.
7. Subject is in good health as determined by vital signs, medical history, physical exam, ECG, and safety laboratory analyses at Screening and during the study.
8. Subject is negative for SARS-CoV-2 virus at admission Day -1 and Day 1 (during the SAD, Fed portion of the study, and MAD).
9. Subject does not have dysphagia and discomfort with swallowing tablets/capsules.

Exclusion Criteria:

1. Subject has used an investigational product or device within 30 days prior to enrollment or during the study.
2. Subject has used prescription or non-prescription drugs (including vitamins, minerals, and herbal/plant-derived preparations) within 2 weeks of enrollment (excluding hormonal IUD, oral hormonal contraceptives, hormone replacement therapy, and acetaminophen) unless deemed acceptable by the Investigator in consultation with the Sponsor.
3. Subject has a positive drug and/or alcohol test at Screening and on Day -1 (including 4. Day -1 of Period 2 for SAD dosing participants, i.e., fed cohort).
4. Subject has a history of drug or alcohol abuse within 2 years before Screening.
5. Subject is unable to abstain from ingesting alcohol or smoking for 72 hours prior to dosing and throughout the study.
6. Concurrent use of probenecid, penicillin or other ß-lactams, or other drugs which undergo active tubular secretion in the kidneys.
7. The subject has a clinically significant history of endocrinologic, hematologic, hepatic, immunologic, metabolic, cardiovascular, urologic, pulmonary, neurologic, dermatologic, psychiatric, renal, and/or other major diseases or malignancy.
8. Allergy to sodium benzoate.
9. Has an active suicidal plan/intent or have had active suicidal thoughts in the past 6 months or a suicide attempt in the past 3 years.
