Eligibility Criteria

Inclusion Criteria

Subjects must meet all the following criteria to be enrolled in the trial:

1. Able to understand and willing to sign the ICF

2. Healthy subjects, male or female, non-smokers, 18-55 years of age

3. No significant medical history, and in good health as determined by detailed medical history (neurological, endocrinal, cardiovascular, pulmonary, hematological, immunologic, psychiatric, gastrointestinal, renal, hepatic, and metabolic disease), full physical examination, vital signs, 12-lead electrocardiogram (ECG), urinalysis and laboratory tests at screening. For eligibility purposes, abnormal laboratory or vital signs results may be repeated once if abnormal result is observed at the initial reading. Moreover, abnormalities found in the ECG may need to be confirmed by repeated measurements.

4. Adequate organ function according to the following laboratory values:

• Bone marrow function (absolute neutrophil count ≥1500/mm3 and platelet count ≥100,000/mm3).
• Alanine aminotransferase (ALT) 7-56 units per liter of serum ( or institutional equivalent), AST 5-40 units per liter of serum (or institutional equivalent), alkaline phosphatase 20-140 units per liter of serum (or institutional equivalent), total bilirubin 0.1-1.0 mg/dL (or institutional equivalent) and creatinine clearance (Cockcroft-Gault equation) ≥90mL/min.

5. Female of non-childbearing potential (i.e., physiologically incapable of becoming pregnant, including any female who is 1 year of post-menopausal with a FSH > 40mIU/mL, or surgically sterile [defined as having a bilateral oophorectomy, hysterectomy or tubal ligation]) or agree to one of the following to prevent pregnancy and, if a woman of childbearing potential, have a negative pregnancy test at screening:

• Practicing abstinence which is the preferred and usual lifestyle of the subject
• If a sexually active woman of childbearing potential (sexually active with a non-sterile male partner) agrees to prevent pregnancy by using double methods of contraception as follow until 180 days after the administration of the investigational product:

1. Simultaneous use of intra-uterine contraceptive device, placed at least 4 weeks prior to study drug administration, and condom for the male partner.

2. Simultaneous use of hormonal contraceptives, starting at least 4 weeks prior to study drug administration and must agree to use the same hormonal contraceptive throughout the study, and condom for the male partner.

3. Simultaneous use of diaphragm with intravaginally applied spermicide and male condom for the male partner, starting at least 21 days prior to study drug administration. Male subjects who are not vasectomized for at least 6 months and who are sexually active with a non-sterile female partner must agree to use double methods of contraception below from the first dose of randomized study drug until 120 days after their dose and must not donate sperm during their study participation period:

<!-- -->

1. Simultaneous use of a male condom and, for the female partner, hormonal contraceptives (used since at least 4 weeks) or intra-uterine contraceptive device (placed since at least 4 weeks)

2. Simultaneous use of a male condom and, for the female partner, a diaphragm with intravaginally applied spermicide

6. Body mass index (BMI) 18.0-32.0 kg/m2 and body weight ≥ 50.0 kg for males and

• 45.0 kg for females

7. Blood pressure ≤ 139/89 mm Hg

3. Known History of hypersensitivity to rice

4. Use of any prescription drugs, herbal supplements, or nonprescription drugs, including oral antihistamines (for seasonal allergies), within 1 month or 5 half-lives (whichever is longer) prior to study drug administration, or dietary supplements within 1 week prior to study drug administration, unless, in the opinion of the Investigator and the Sponsor, the medication will not interfere with the study. Over-the-counter multivitamins will be permitted. If needed, paracetamol/acetaminophen may be used, but must be documented in the Concomitant medications/Significant non-drug therapies page of the source data. Any questions of concomitant medications should be directed to the Sponsor.

5. Participation in a clinical research study involving the administration of an investigational or marketed drug or device within 30 days prior to the first dosing, administration of a biological product in the context of a clinical research study within 90 days prior to the first dosing, or concomitant participation in an investigational study involving no drug or device administration.

6. Donation of blood 12 week prior to dosing

7. Pregnant, or nursing females

8. A history of psychiatric and psychological condition that, in the judgment of the Investigator, may interfere with the planned treatment and follow-up, affect subject compliance or place the subject at high risk from treatment-related complications

9. A marked baseline prolongation of QT/QTc interval (e.g., repeated demonstration of a QTc interval >450 milliseconds [ms], Bazett Formula: QTc=QT/RR0.5）

10. Active hepatitis B or C. HBV carriers without active disease (HBV DNA titer< 1000 cps/mL or 200 IU/mL), or cured Hepatitis C (negative HCV RNA test) may be enrolled, in the judgement of the Investigator.

11. Known infection with human immunodeficiency virus (HIV) and a cluster of differentiation 4 (CD4) count that is unknown or documented to be < 350 cells/mm3 within 12 months, or an Acquired Immune Deficiency Syndrome (AIDS)-defining illness

12. Known history of severe IgA deficiency

13. Immunization with a live or attenuated vaccine is prohibited within 4 weeks prior to study drug administration. Seasonal influenza vaccines for injection are generally killed virus vaccines and are allowed; however, intranasal influenza vaccines (e.g., FluMist®) are live attenuated vaccines and are not allowed

14. Receipt of an immunoglobulin or blood product 90 days prior to dosing

15. History of consuming more than 14 units of alcoholic beverages per week or of alcoholism or drug/chemical/substance abuse within past 2 years prior to screening (Note: one unit = 12 ounces of beer, 4 ounces of wine or 1 ounce of spirits). Consumed > 3 (male) or 2 (female) units of alcohol as determined by blood alcohol testing at screening

16. History of significant drug abuse within one year prior to screening

17. Positive urine drug screen (amphetamines, barbiturates, benzodiazepines, cannabinoids, cocaine, cotinine and opiates)

18. Any reason which, in the opinion of the Investigator, would prevent the subject from participating in the study

• Minimum Eligible Age: 18 Years
• Maximum Eligible Age: 55 Years
• Eligible Sex: ALL
