Brief Summary:
The purpose of this study is to evaluate the safety, tolerability and characterize the PK, PD f\profile.

Condition or disease Intervention/treatment Phase
Healthy Male Drug: GCC-4401 Drug: GCC-4401C Phase 1

Detailed Description:
The primary objective of this study is to investigate the safety and tolerability following administration of single ascending doses of GCC4401C in healthy male subjects; and the secondary objective of this study is to characterize the single-dose PK profile after oral administration of GCC-4401C, and to determine an appropriate dose range and dosing regimen of oral GCC-4401C for subsequent clinical trials.

Primary Outcome Measures :
  1. The number and percentage of subjects experiencing 1 or more AEs will be summarized by treatment/dose group, relationship to study drug, and severity. [ Time Frame: up to 7 ~ 10 days after administraion ]
  2. Statistics for clinical laboratory data(continuous variables only), vital signs, and ECF intervals will be presented for each evaluation during the study and for change from baseline to postdose evaluations. [ Time Frame: up to 7 ~10 days after administration ]

Secondary Outcome Measures :
  1. the single-dose pharmacokinetic behavior [ Time Frame: at predose and at 0.25, 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 12, 16, 24, and 48 hours postdose ]

    to characterize the single-dose pharmacokinetic behavior after oral administration of GCC-4401C

    • maximum plasma concentration (Cmax);
    • time to Cmax (tmax);
    • terminal rate constant (λz);
    • area under the curve from zero to the time of the last measurable concentration [AUC(0-last)];
    • area under the curve from zero to infinity [AUC(0-inf)];
    • apparent terminal half-life (t½);
    • apparent systemic clearance (CL/F);
    • apparent volume of distribution (Vz/F);
    • renal clearance (CLr); and
    • fraction of drug (fe) excreted unchanged in urine (% of dose).

Other Outcome Measures:
  1. the single-dose pharmacodynamics behavior [ Time Frame: at predose and at 0.25, 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 12, 16, 24, and 48 hours postdose ]
    • PT;
    • aPTT;
    • INR;
    • coagulation factor X assay;
    • If the assay for coagulation factor X is abnormal a reflex inhibitor screen will be performed. This test will not be run on coagulation factor X assay results which are within normal range.
    • anti factor Xa assay;
    • escarin-stimulated thrombin activity; and
    • antithrombin (III) activity.

Layout table for eligibility information
Ages Eligible for Study:   18 Years to 55 Years   (Adult)
Sexes Eligible for Study:   Male
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  1. Capable of understanding and complying with the requirements of the study and have signed the informed consent form (ICF);
  2. Normal healthy males between 18 and 55 years of age, inclusive, at the time of consent;
  3. A body mass index (BMI) of at least 18.5 kg/m2 but no more than 30 kg/m2 (BMI is defined as the subject's weight in kilograms divided by the square root of the subject's height in meters);
  4. In general good health based on screening medical history, physical examination (defined as the absence of any clinically significant abnormalities), vital signs, and clinical laboratory values (hematology, serum chemistry, and urinalysis);
  5. Have a normal ECG (defined as Fridericia's correction for QT interval [QTcF] less than or equal to 450 ms) at screening, Day -1 and Day 1, predose (baseline). Repeat ECG measurements will be allowed at the baseline assessment for QTcF values above 450 ms and the average will be used to assess eligibility.
  6. Male subjects must use barrier contraception during sexual intercourse, ie, condoms, from the first day of dosing until 3 months after the last dosing with GCC-4401C; and
  7. Nonsmokers (defined as not having smoked or used any nicotine containing products for at least 1 month, and having a urine cotinine less than 400 ng/mL).

Exclusion Criteria:

Subjects presenting with any of the following will not be entered into the study:

  1. Have clinically significant abnormal history, physical findings, or laboratory values at the prestudy screening assessment that could interfere with the objectives of the study or the safety of the subjects;
  2. Have any of the following, which may put them at increased risk with anticoagulant use:

    • family history or personal history of bleeding disorders or diseases/syndromes that can either alter or increase the propensity for bleeding;
    • severe trauma, fracture, major surgery, or biopsy of a parenchymal organ within the past 3 months;
    • endoscopic peptic-ulcer disease within the past 3 years or clinically significant gastrointestinal, genitourinary, or gum bleeding within the past 3 months;

    • any history of thrombotic or hemorrhagic stroke;
    • clinically significant laboratory abnormalities (hemoglobin less than 12.0 g/dL, prolonged PT or INR, prolonged aPTT, elevated liver enzymes, elevated serum creatinine or blood urea nitrogen (BUN) which is considered clinically significant by the Investigator, or platelet count less than 150,000/mm3 or greater than 600,000/mm3). Mildly elevated BUN with normal serum creatinine values which are determined not to be clinical significant by the Investigator are permitted. These significant laboratory values may be repeated for confirmation; or
    • any other contraindication to anticoagulant treatment, or increased bleeding risk, as judged by the Investigator.
  3. Have known positive test for hepatitis B surface antigen, hepatitis C antibody, human immunodeficiency virus (HIV) 1, or HIV 2;
