About

This is a Phase 1, FIH, randomized, double-blind, placebo-controlled study to evaluate the safety, tolerability, and PK characteristics of ENC1018 after single and multiple oral dose administration in healthy adult subjects.

The study will be conducted in two parts: Part A -Single ascending Dose (SAD) and Part B - Multiple ascending dose (MAD). A Food Effect Cohort will be conducted within Part A. Part A is for the single dose use of IP, while Part B is once daily use for 14 consecutive days.

Approximately 72 healthy adult subjects are planned to be enrolled. Each subject will be enrolled in only one cohort of either Parts A or B of the study, to receive only one dose regimen during the study. Part B may be initiated in parallel or prior to completion of Part A, at the discretion of Safety Review Committee (SRC), upon reviewing safety and plasma PK data.

Enrollment: 72 patients

Sex: All

Ages: 18 to 55 years old

Volunteers: Accepts Healthy Volunteers

• Any disease or surgical procedure (including cholecystectomy) that may substantially affect IP absorption, distribution, metabolism, and excretion as judged by the Investigator
• Any current active infections, including localized infections, or any recent history (within 1 week prior to IP administration) of active infections, cough, or fever; or a history of recurrent or chronic infections.
• Dosing with any other investigational drug or therapy within 90 days prior to dosing.
• Is positive for HBsAg,HCVAb, HIVAb, or tuberculosis.
