E.3 | Principal inclusion criteria |
1. Male or female between 18 and 75 years of age (inclusive). 2. Capable of giving written informed consent and able to effectively communicate with the investigator and study personnel. A signed informed consent form (ICF) must be on file prior to initiating the Screening procedures. 3. Willing and able to complete all study requirements, restrictions, visits and procedures. 4. Histologic evidence of NASH based on central readings of the screening biopsy obtained no more than 6 months before Screening defined by presence of all 3 key histological features, Nonalcoholic Fatty Liver Disease Activity Score (NAS) ≥ 4 with at least 1 point each in lobular inflammation and hepatocyte ballooning a. Historical biopsy may be substituted for Screening biopsy to determine eligibility if the following are met: i. Historical biopsy was obtained no more than 180 ± 5 days prior to the first day of Screening. ii. Hepatic tissue or slides are available for central histologic evaluation. iii. No new therapeutic intervention for NASH was made 90 days prior to screening (e.g., obeticholic acid, vitamin E ≥ 400 IU/day, pioglitazone, incretins [e.g., liraglutide, semaglutide], sodium-glucose cotransporter-2 [SGLT2] inhibitors). iv. Subjects must have been metabolically stable since the biopsy (no significant weight loss ≥ 7% of body weight, no major deterioration of glycemic control, and no introduction of new or investigational drugs for the treatment of Type 2 Diabetes 5. Histologic liver fibrosis stage 2 or 3 as defined by the Nonalcoholic Steatohepatitis Clinical Research Network (NASH CRN) scoring of liver fibrosis based on central reading of the Screening biopsy (refer to criteria 4a regarding use of a historical biopsy as a substitute for the Screening biopsy). 6. Blood pressure up to 160/100 mmHg; potential subjects who meet other eligibility requirements, but who have out of range blood pressure measurements deemed to be not clinically significant by the investigator, may still be considered for study inclusion. 7. Females of reproductive potential, defined as women who have not been postmenopausal for at least 12 consecutive months (i.e., who have had menses within the preceding 12 months), or women who have not undergone surgical sterilization, specifically, hysterectomy, bilateral salpingectomy, bilateral oophorectomy, hysteroscopic sterilization, and/or tubal ligation, must have a negative pregnancy test at Screening and prior to dosing at Day 1. 8. All participants must agree not to participate in a conception process (i.e., active attempt to become pregnant or to impregnate, sperm or egg donation, in vitro fertilization). If participating in sexual activity that could lead to pregnancy, the participant must agree to use 2 reliable methods of contraception simultaneously while receiving study treatment and for 3 months after subject has stopped taking study drug. A combination of TWO of the following methods MUST be used appropriately: a. Condoms (male or female) with or without a spermicidal agent. b. Diaphragm or cervical cap with spermicide. c. Intrauterine device (IUD). d. Hormonal-based contraception. Note: Participants who are not of reproductive potential (women who have been postmenopausal for at least 12 consecutive months or have undergone hysterectomy, bilateral salpingectomy, bilateral oophorectomy, hysteroscopic sterilization, and/or tubal ligation, or men who have documented azoospermia) are eligible without requiring the use of contraceptives. Acceptable documentation of sterilization, menopause or male partner’s azoospermia must be provided; serum follicle stimulating hormone (FSH) measurement can be used to document menopausal status. |
