Brief summary
This is a phase I, open-label, dose-escalation, multiple-dose study to investigate pharmacokinetics and safety of JT001 in Caucasian healthy subjects. The study consists of three dose level (200, 400, 600 mg). and the participant will be sequentially assigned from low-dose group to high-dose group to receive the JT001 at one of the three doses according to the dose escalation scheme. The total duration of participants in the study will be of 14 to 26 days. The study includes a screening phase (up to 14 days), a 6-day multiple-dose phase (D1-D6), a 3-day safety observation phase (end of administration) and 4-day safety follow up period. Total approximately 27 participants will be enrolled in the study. Each group of dose level will enroll approximately 9 participants. Oversight of the study will be provided by a committee (the Safety Review Committee) comprising a representative of the Sponsor or Sponsor’s designee, the investigator, and the medical monitor.

Inclusion criteria
1. Healthy Caucasian male or female (excluding Middle East) subjects aged 18 to 55 years (inclusive at the time of informed consent). Caucasians are defined as subjects who have 2 parents of Caucasian/European ancestry and 4 grandparents of Caucasian/European ancestry. 2. Subjects must have a Body Mass Index (BMI) greater than 18.0 and equal to or less than 32.0 kg/m2 at Screening with Body weight: male more than 50 kg, female more than 45 kg. 3. Subjects must be in good general health, have no clinically significant abnormalities on vital signs, physical examination, laboratory test, ophthalmology, ECG and B-ultrasonography at Screening and/or before administration of the initial dose of the study drug. 4. Women of childbearing potential (WOCBP) must have a negative serum or urine pregnancy test within 24 hours prior to the start of study drug and must not be breastfeeding, lactating or planning pregnancy during the study period. WOCBP are defined as any female who has experienced menarche and who has not undergone surgical sterilization (hysterectomy or bilateral oophorectomy) and is not postmenopausal. Menopause is defined as 12 months of amenorrhea in the absence of other biological causes. In addition, females under the age of 55 years must have a documented serum follicle stimulating hormone (FSH) level greater than 40mIU/mL to confirm menopause. Male participants with potentially postmenopausal partners who are under the age of 55 years must use condoms unless their partner’s postmenopausal status has been confirmed by FSH level. WOCBP who are not exclusively in same-sex relationships and males with partners of child-bearing potential must agree to use adequate contraception. For WOCBP, contraception should be continued for 32 days after the final dose of study drug. For males, contraception should be continued for 92 days after the final dose of study drug. In addition, males must not donate sperm for 92 days after the final dose. Males and WOCBP who are continuously not heterosexually active are exempt from contraceptive requirements. However, WOCBP must still undergo pregnancy testing as per protocol. Investigators will counsel WOCBP and male participants who are sexually active with WOCBP on the importance of pregnancy prevention and the implications of an unexpected pregnancy. Investigators will advise on the use of an adequate methods of contraception, which is defined as use of a condom by the male partner combined with use of a highly effective method of contraception by the female partner. A highly effective method of contraception is one that has a failure rate of less than 1% when used consistently and correctly. Male participants must inform their female partners who are WOCBP of the contraceptive requirements of the protocol and are expected to adhere to using contraception with their partner. Highly effective methods of contraception are listed below: • Hormonal methods of contraception including oral contraceptives containing combined estrogen and progesterone, a vaginal ring, injectable and implantable hormonal contraceptives, intrauterine hormone-releasing system (e.g. Mirena) and progestogen-only hormonal contraception associated with inhibition of ovulation • Nonhormonal intrauterine device (IUD) • Bilateral tubal occlusion • Vasectomised subject/partner with documented azoospermia 90 days after procedure, if that partner is the sole sexual partner. For female participants, include wording that hormonal contraceptives should begin at least 1 month prior to screening to ensure contraceptive is in full effect. Complete abstinence, defined as the complete avoidance of heterosexual intercourse - is an acceptable form of contraception if used consistently throughout the duration of study and for the durations after dosing specified for males and females above. It is not necessary to use any other method of contraception when complete abstinence is elected. WOCBP who choose complete abstinence must continue to have pregnancy tests as per protocol. The reliability of sexual abstinence needs to be evaluated by the Investigator in relation to the duration of the clinical trial and the preferred and usual lifestyle of the subject. 5. Subjects must be willing and able to provide written informed consent after the nature of the study has been explained and before the commencement of any study procedures.
Exclusion criteria
1. Known history of allergy to the study drug. 2. History of severe allergic or anaphylactic reactions. 3. Subjects with confirmed diseases in the central nervous system, cardiovascular system, digestive system, respiratory system, urinary system, blood system, metabolic disorders, etc., and require medical intervention, or other diseases that are not suitable for participating in clinical studies (such as psychiatric history, etc.). Subjects with mild depression and anxiety may be enrolled if stable and not medicated. 4. Medical history considered by the Investigator to impact the assessment of PK profiles. 5. Blood donation or blood loss more than 400 mL before screening or has used blood products. Subjects who have donated blood within 1 month or plasma donation within 7 days of Screening will not be included in the study. 6. Subjects who have received treatment with another investigational drug within 3 months of screening or is participating in another study at the time of screening. 7. Use of any prescription drugs, over the counter (OTC) medication, herbal remedies, supplements, or vitamins within 1 week before screening. Taking paracetamol (up to 2000 mg/day) is allowed. 8. Subjects with alcohol addiction within 1 year before screening, defined as drinking more than 14 units per week (1 unit is equivalent to approximately 200 mL of beer with 5% alcohol content, or 25 mL of spirits with 40% alcohol content, or 85 mL of wine with 12% alcohol content). 9. Subjects who have a history of smoking more than 10 cigarettes a day or the equivalent amount within 1 year before screening will not be included. Light smoking (e.g., 10 cigarettes/week) within 1 month prior to screening is acceptable as long as the participant is willing to abstain from smoking during inpatient stay. 10. Subject is unwilling to abstain from smoking or alcohol during the study. 11. Positive test for hepatitis B surface antigen (HBsAg), hepatitis C virus antibody (Anti-HCV), Treponema pallidum antibody, and human immunodeficiency virus (HIV) antibody at Screening. 12. Subjects with abnormal ALT or AST value that is considered clinically by the Investigator at Screening will not be included in the study. 13. Glomerular filtration rate (eGFR) less than lower limit of normal (LLN) at Screening. The CKD-EPI formula will be used for the eGFR calculation. 14. Abnormal ECG findings considered by the Investigator to be clinically significant, single-examination QTcF (heart rate corrected) more than 450 ms in males and more than 470 ms in females, and/or other clinically significant abnormalities at Screening. 15. Pregnant or lactating at Screening or planning to become pregnant (self or partner) from Screening until 3 months after the last administration of the study drug. 16. Subject is considered to have other factors, in the opinion of the Investigator, which would make it unlikely that the subject will comply with the protocol or complete the study per protocol. 17. Subjects who received any COVID-19 vaccination within 14 days prior to the first administration of the study drug will not be included in the study. 18. Any other condition that would, in the Investigator's judgement, contraindicate the patient's participation in the clinical study due to safety concerns or compliance with clinical study procedures or interpretation of study results.
