The Safety, Tolerability, and Pharmacokinetic Study of SC1011 in Healthy Subjects.

Study Overview
=================
Brief Summary
-----------------
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.

Detailed Description
-----------------
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.

Eligibility Criteria
-----------------
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. Exclusion Criteria: Significant history or clinical manifestation of any metabolic, allergic, dermatological, hepatic, renal, hematological, pulmonary, cardiovascular, gastrointestinal, neurological, respiratory, endocrine, or psychiatric disorder, as determined by the Investigator (or designee). History of significant hypersensitivity, intolerance, or allergy to any drug compound, food, or other substance. Alcohol consumption of > 21 units per week for males and > 14 units for females. One unit of alcohol equals 12 oz (360 mL) beer, 1½ oz (45 mL) liquor, or 5 oz (150 mL wine), or a positive alcohol breath test at Check-in. Any screening laboratory or ECG results are not within the normal reference range and are considered clinically significant. Participants who participated in other clinical trials within 3 months prior to administration. Blood donation or blood loss exceeding 400 mL within 2 months prior to administration. Participants who smoked, drank alcohol, tea, food or drink containing xanthine or caffeine, or had strenuous exercise, or had other factors affecting drug absorption, distribution, metabolism and excretion 2 days before drug administration. Subjects who, in the opinion of the Investigator (or designee), should not participate in this study.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Incidence and severity of adverse events and serious adverse events related drug. | Adverse events are coded according to the ICH Medical Dictionary of Regulatory Activities (MedDRA 24.0 or above). ADR: Adverse events that are definitely related, probably related, or undetermined in relation to the investigational drug. | Evaluations will be conducted for up to 7 days after first administration | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Geometric Mean of Maximum Observed Plasma Concentration of SC1011 | Peak concentration. It was directly obtained from the measured data of blood concentration and time. | Evaluations will be conducted for up to 7 days after first administration | 
| Area under the plasma concentration-time curve (AUC) from time zero to infinity of SC1011 | The area under the curve extrapolated from zero to infinity. AUC0-∞=AUC0-t+Ct/λz(Ct is the last determinable blood concentration, λz is elimination rate constant). | Evaluations will be conducted for up to 7 days after first administration |
