To Determine Safety and Tolerability of MG-S-2525 and to Evaluate Its PK Profile in Healthy Volunteers
To Determine Safety and Tolerability of MG-S-2525 and to Evaluate Its PK Profile in Healthy Volunteers
This is a Phase I stage to investigate the safety and tolerability of MG-S-2525 in healthy
 volunteers. The proposed trial consists of 3 study parts to be conducted at Tri-Service
 General Hospital and includes Single Ascending Dose (SAD), Multiple Ascending Dose (MAD) and
 Food Effect parts. This study will enroll up to 16 evaluable subjects in the SAD part, 36
 evaluable subjects in the MAD part and enroll up to 20 evaluable subjects for the Food Effect
 part.
Inclusion Criteria:

 Single ascending dose (SAD), Multiple ascending dose (MAD) and Food Effect Parts:

 1. Healthy male volunteers

 2. Subject's age is no less than 20 years old

 3. Subjects whose body mass index (BMI) at screening is within a range of ≥18.5 kg/m2 and
 <25.0 kg/m2.

 BMI = Body Weight (kg) / [Height (m)]2 Body weight is not less than 50 kg

 4. Subjects who are judged to be in good health by the investigator based upon the
 results of physical examinations, chest X-ray (within 180 days prior to the first dose
 of the study) and routine laboratory tests.

 5. Subjects did not take any of the following medications in the specified durations:

 -  Any systemically-absorbed medication (excluding vitamins, food supplements, and
 hormone contraceptives for birth control) within 14 days prior to the first dose
 of the study

 -  Any enzyme inducer/inhibitor and/or known hepatic or renal clearance-altering
 agents (e.g., erythromycin, cimetidine, barbiturates, phenothiazine,
 clarithromycin, troleandomycin, ketoconazole, miconazolem fluconazole,
 itraconazole) within 30 days prior to the first dose of the study

 6. Subjects are willing to comply with protocol-stated requirements, instructions and
 restrictions, followed by understanding and signing the written informed consent form.

 Extra Criteria for the MAD and Food Effect Parts

 7. Healthy female volunteers whose body weight is not less than 45 kg

 8. Female subjects show negative pregnancy test results within 30 days prior to the first
 study dose.

 9. Female subjects of child-bearing potential, committing to practicing sexual abstinence
 or using and continue to use a medically acceptable form of birth control for at least
 1 month prior to screening (that period will extend to 3 months for oral contraceptive
 use) and for at least 30 days after the last dose of study drug. For a subject to be
 considered not to be of child-bearing potential, she must have been amenorrheic for at
 least 2 years, or must have had a hysterectomy, a bilateral tubal ligation, and/or a
 bilateral oophorectomy (as determined by the medical history). The male partner of a
 female study subject with childbearing potential must use a condom and ensure that his
 partner uses a suitable method of contraception as outlined above.

 Extra Criteria for the MAD Part

 10. Subjects who are self-reporting current smokers (>10 pack/years).

 Exclusion Criteria:

 SAD, MAD and Food Effect Parts:

 1. Subjects with any properly diagnosed disease within 30 days prior to the first dose of
 the study.

 2. Subjects with a clinically significant hematological, endocrine, cardiovascular,
 hepatic, renal, gastrointestinal, and/or pulmonary disorder; subjects with any
 predisposing condition that might interfere with the absorption, distribution,
 metabolism and excretion of drugs; subjects who has had any previous gastrointestinal
 surgery, except appendectomy if performed >90 days prior to the first dose of the
 study

 3. Subjects had participated in investigational drug trials and took any investigational
 drug within 60 days prior to the first dose of the study.

 4. Subjects had blood donation of more than 250 and 500 mL within 60 and 90 days,
 respectively prior to the first dose of the study.

 5. Subjects had a history of drug abuse or alcohol abuse according to the Diagnostic and
 Statistical Manual of Mental Disorders 4th edition (DSM-IV) criteria.

 6. Subject's medical history shows contraindications or hypersensitivity to the use of
 test medications [HL0 or any component of drug products].

 8. Subjects who cannot stop caffeine-intake for 48 hours prior to the first study dose
 and during the entire study period.

 9. Subjects with underlying medical, mental or psychological conditions that would impair
 treatment compliance, or in the opinion of the investigator would not permit to
 participate in the study

 10. Subjects who have received or are taking any medications that may interfere the
 assessment [e.g., anti-inflammatories, anti-asthma/COPD (chronic obstructive pulmonary
 disease) and anti-IPF (idiopathic pulmonary fibrosis) medications] for a period of up
 to 14 days prior to the first dose of the study Extra Criteria for the MAD and Food
 Effect Parts

 11. Female subjects who are lactating Extra criteria for the MAD part

 12. Subjects who did not smoke for more than 2 days prior to the first dose of the study
 or during the study period
