Clinical Trial Summary

This is a single-site, randomized, double-blind, double dummy, placebo-controlled single and multiple doses study of Aramchol in healthy Chinese volunteers. The subject population that was enrolled for Aramchol 004 was not specifically designed to understand the PK profile of Aramchol in subjects of Chinese descent. Therefore, this study (Aramchol 015) has been undertaken to ascertain the PK profile of Aramchol following single and multiple doses in a Chinese population under fed conditions utilizing the light breakfast from Aramchol 004.

This study will consist of two parts and the subjects will be assigned to two parts.

In each part of the study, subjects will be enrolled in the study within 28 days of screening.

Description:

In each part of the study, subjects will be enrolled in the study within 28 days of screening. The study will consist of two parts, and the subjects will be assigned as follows: Part A- single escalating doses This part of the study is a single-site, randomized, double-blind, double dummy, placebo-controlled single-dose study of Aramchol in healthy Chinese volunteers. The purpose of Part A is to evaluate the PK, safety and tolerability of Aramchol tablets at single doses of either 400 mg or 600 mg.

Thirty-two (32) subjects will participate in this part of the study and will be randomized to receive a single-dose of 400 mg Aramchol, 600 mg Aramchol, or Placebo. Drug administration will be preceded by a light breakfast consumed within 1 hour prior to dosing. All drugs will be administered by the study staff. In order to maintain blinding, all subjects will receive two tablets on each dosing, according to the following administrations:

• Cohort A: 1 x 200 mg Placebo tablet + 1 x 400 mg Aramchol tablet (12 subjects)

• Cohort B: 1 x 200 mg Aramchol tablet + 1 x 400 mg Aramchol tablet (12 subjects)

• Cohort C: 1 x 200mg Placebo tablet + 1 x 400 mg Placebo tablet (8 subjects) Subjects will be admitted in-house in the evening before the first study drug administration (Day 0) and will remain in-house for 36 hours after dosing. Blood samples for Aramchol concentrations will be drawn for 36 hours at designated time points as described below. Additional ambulatory samples will be collected at 48, 72, 96, and 144 hours postdose. Subjects will be continuously monitored for safety. An End-of Study/Safety Follow-up visit will take place on the last PK sampling day, ie, 144 hours after the last dose administration.

If the PK profile from Part A is similar to the existing PK data in non- Chinese subjects, then the study may be stopped. If the PK profile is different, then Part B of the study may be performed.

Part B- multiple escalating doses Part B of the study is a single-site, randomized, double-blind, doubledummy, placebo-controlled multiple-dose study of Aramchol in healthy Chinese volunteers. The purpose of this part is to evaluate the PK, safety and tolerability of Aramchol tablets at multiple administrations of two different doses. Thirty-two (32) subjects will participate in this part of the study and will be equally randomized to receive 400 mg Aramchol, 600 mg Aramchol, or Placebo for 10 consecutive days. Screening for Part B may begin during PK analysis of Part A. Part A subjects can enroll into Part B with sponsor approval. Drug administration will be preceded by a light breakfast consumed within 1 hour prior to dosing. All drugs will be administered by the study staff. In order to maintain blinding, all subjects will receive two tablets on each dosing, according to the following administrations:

• Cohort D: 1 x 200 mg Placebo tablet + 1 x 400 mg Aramchol tablet (12 subjects)

• Cohort E: 1 x 200 mg Aramchol tablet + 1 x 400 mg Aramchol tablet (12 subjects)

• Cohort F: 1 x 200 mg Placebo tablet + 1 x 400 mg Placebo tablet (8 subjects) Subjects will be admitted in-house in the evening before the first study drug administration (Day 0) and will remain in-house for 24 and 36 hours after first (Day 1) and last (Day 10) doses, respectively; subjects will return for all other visits. PK blood samples will be drawn on Day 1 over 24 hours at designated time points as described below. Additionally, pre-dose (trough) samples will be drawn before dosing on Days 2, 3, 4, 5, 7, 8, and 9. On Day 10, blood samples will be collected over 36 hours at designated time points as described below and during additional visits at 48, 96, 120, 144, 168 and 192 hours post-dose. Subjects will be continuously monitored for safety. An End-of Study/Safety Follow-up visit will take place on the last PK sampling day, ie, 192 hours after the last dose administration.

2. BMI = 18.0 and = 30.0.

3. Subjects in general good health in the opinion of the investigator as determined by medical history, vital signs and physical examination.

4. No significant abnormalities in ECG (eg, prolonged QTcF, prolonged PR interval) done at screening and on Days (0) before dosing session.

5. No clinically significant abnormalities in hematology, blood chemistry, or urinalysis lab tests at screening.

6. No known history of alcohol or drug abuse. Subjects with negative urinary drugs of abuse (DOA) screen determined on Day (0) before dosing session(s).

7. Negative human immunodeficiency virus (HIV), hepatitis B, and hepatitis C serology tests as evaluated at screening.

8. Negative urine pregnancy tests at screening and at check-in (women of childbearing potential only).

9. . Subjects must be able to adhere to the visit schedule and protocol requirements and be available to complete the study.

10. All subjects must agree to use a highly effective method of birth control during the study and up to 15 days after the last study drug administration. A highly effective method of birth control is considered to be one of the following:

• An oral or implanted hormonal method of contraception (if it had been used for =3 months prior to study drug administration) while also using a barrier method (ie, condom or diaphragm)

• A hormone or copper intrauterine device if it had been in place for =3 months prior to study drug administration (subjects using nonhormonal or copper intrauterine devices were also required to use a barrier method of contraception)

• Total abstinence is acceptable; however, the subject is required to use a highly effective method of contraception if the subject decides subsequently not to abstain

• Periodic abstinence around ovulation is not considered acceptable

• Women who are either surgically sterilized or postmenopausal (last menstrual period at least 1 year prior to the screening visit) are exempt from this requirement. If medical records are not available to document sterility, urine pregnancy testing will be performed at screening and check-in.
