Intervention model description: Subjects will be randomized in a 1:1 ratio to one of two treatment sequences with 11 subjects per treatment sequence as outlined below. Each subject will receive both treatments (Treatment A and Treatment B) with a washout period of at least 7 days between successive SLC-391 single doses.
Primary purpose: TREATMENT

Brief summary: This will be a single center, Phase 1, open-label, randomized, single dose, 2-period, 2-sequence, crossover study to evaluate the PK, safety, and tolerability of a single oral dose of SLC-391 under fed and fasted conditions in approximately 22 healthy male and non-childbearing potential female subjects.

Subjects will be randomized in a 1:1 ratio to one of two treatment sequences with 11 subjects per treatment sequence. Each subject will receive both treatments (Treatment A and Treatment B) with a washout period of at least 7 days between successive SLC-391.

1. Evidence of a personally signed and dated informed consent document indicating that the subject has been informed of all pertinent aspects of the study.
2. Male or non-childbearing potential female, non-smoker (no use of tobacco or nicotine products within 3 months prior to screening, confirmed by cotinine test), ≥18 and ≤55 years of age, with body mass index (BMI) \>18.5 and \<30 kg/m2 and body weight ≥50.0 kg for males and ≥45.0 kg for females.
3. Healthy as defined by:

   1. The absence of clinically significant illness and/or surgery within 4 weeks prior to dosing.
   2. The absence of clinically significant history of neurological, endocrine, cardiovascular, respiratory, hematological, immunological, psychiatric, gastrointestinal, renal, hepatic, and metabolic disease.
4. Non-childbearing potential female defined as:

   1. Post-menopausal (spontaneous amenorrhea for at least 12 months prior to dosing) with confirmation by documented follicle stimulating hormone (FSH) levels ≥ 40 mIU/mL; or
   2. Surgically sterile (bilateral oophorectomy, hysterectomy or tubal ligation at least 3 months prior to dosing, verified through medical records). If surgical sterility cannot be verified, female subjects who are sexually active with a non-sterile male partner (sterile male partners are defined as men vasectomized for at least 3 months prior to dosing) must be willing to use one of the following acceptable contraceptive methods throughout the study and for 90 days after the last dose:

   (i) Simultaneous use of hormonal contraceptive (e.g., oral, patch, depot injection, implant, vaginal ring, intrauterine device) or non-hormonal intrauterine device used for at least 4 weeks prior to dosing (must agree to use the same contraceptive throughout the study) and condom for the male partner; (ii) Simultaneous use of diaphragm or cervical cap with spermicide and condom for the male partner, started at least 21 days prior to dosing.
5. Male subjects who are sexually active with a female partner of childbearing potential (childbearing potential females are defined as women that are neither post-menopausal nor surgically sterile) must be willing to use one of the following acceptable contraceptive methods from the first dose and for 90 days after the last dose, unless they can provide medical records indicating that they have been vasectomized for at least 3 months prior to dosing:

   1. Simultaneous use of condom and, for the female partner, hormonal contraceptives used since at least 4 weeks prior to sexual intercourse or intrauterine contraceptive device placed for at least 4 weeks prior to sexual intercourse;
   2. Simultaneous use of condom with spermicide and a diaphragm or cervical cap for the female partner.
6. Male subjects must be willing not to donate sperm during the study and for 90 days after the last dose.
7. Willing and able to comply with all scheduled visits, treatment plan, laboratory tests and all other required study procedures.

Exclusion Criteria:

1. Any clinically significant abnormality at physical examination, clinically significant abnormal laboratory test results or positive test for human immunodeficiency virus (HIV) antigen, hepatitis B surface antigen (HBsAg), or hepatitis C virus (HCV) antibody found during medical screening.
2. Positive urine drug screen, alcohol breath test or urine cotinine test at screening.
3. History of allergic reactions to SLC-391 or to any excipient in the formulation.
4. History of clinically significant allergy or hypersensitivity to any drug or food or other substance.
5. History of lactose or galactose intolerance, lactase deficiency, or glucose-galactose malabsorption.
6. Positive pregnancy test at screening or breastfeeding subject.
7. Male subjects with partners that are currently pregnant or planning to become pregnant during the study or within 30 days following the last dose of the study drug.
8. Clinically significant ECG abnormalities (Fridericia's corrected QT interval \[QTcF\] ≥450 msec) or vital sign abnormalities (systolic blood pressure \[BP\] lower than 90 or over 140 mmHg, diastolic BP lower than 50 or over 90 mmHg, heart rate \[HR\] less than 50 or over 100 beats per minute \[bpm\]), or respiratory rate (RR) less than 8 or over 20 respirations per minute (rpm) at screening.
9. History of or a family history of congenital QT prolongation or with a history of risk factors for torsade de pointes (e.g., heart failure, hypokalemia, family history of long QT Syndrome), or use of concomitant medications that prolong the QT/ QT interval corrected for HR (QTc interval).
10. History or presence of sustained or symptomatic bradycardia (≤40 bpm), left bundle branch block, ventricular arrhythmia excluding premature ventricular contractions (PVCs) or uncontrolled ventricular arrhythmia. Subjects with a supraventricular arrhythmia not requiring medical treatment and a normal ventricular rate are eligible.
