The goal of this clinical trial is to learn about the safety, tolerability and pharmacokinetic profiles of SC1011,in health conditions. The main questions it aims to answer are:

Safety and tolerability profiles in healthy subjects.Pharmacokinetic profiles in healthy subjects.Food effect in healthy subjects.Participants will complete the study including screening period, dosing period, and observation period. Researchers will compare the inhibitory activity of SC1011 tablets with pirfenidone capsules against the same biomarkers(e.g. blood TNFα) to see if they are different between the two drugs.

This is a double-blind, placebo-controlled, single, and multiple oral dose study conducted in 2 parts.Part A will comprise a single-dose, sequential-group study incorporating a food effect evaluation. Part B will comprise a multiple-dose, sequential-group study.

Inclusion Criteria:

• Males or females, of any race, between 18 and 45 years of age, inclusive, at Screening.
• Body mass index between 18.0 and 32.0 kg/m2, inclusive, at Screening.
• In good health, determined by no clinically significant findings from medical history, physical examination, 12-lead ECG, vital sign measurements, and clinical laboratory evaluations at Screening and/or Check-in as assessed by the Investigator.
• Females will be nonpregnant and nonlactating. Females of childbearing potential and male subjects will agree to use contraception.
• Able to comprehend and willing to sign an informed consent form (ICF) and to abide by the study restrictions.
