Pharmacokinetics and Safety Study of Probucol by Multiple Administration in Healthy Male Subjects

Phase 1

Completed

• Conditions: Healthy
• Interventions: Drug: Probucol

• Registration Number: NCT01590901
• Lead Sponsor: Otsuka Beijing Research Institute

Brief Summary

The Objectives of this study is to evaluate the pharmacokinetics and safety of multiple oral doses of probucol in healthy male subjects.

Detailed Description

This is a single dose, single period, multiple administration, open-labeled trial in one investigation center.

The screening examination will be completed from Day -14 to Day -2 before investigational medicinal product (IMP) administration. The subjects will be hospitalized on Day -1. From Day 1 (the next day), the subjects will receive probucol twice daily (BID). for 14 consecutive days. On Day 18, the subjects can be discharged after the safety evaluation. The follow-up visit will occur on Day 6, 9, 12, 15, 19, 27 (totally 41 days) after the final dosing day.

Exclusion Criteria

1. Subjects with hypersensitivity or a history of hypersensitivity to any drug (any prescription or over-the-counter [OTC] drug)

2. Subjects who meet any of the following lipid criteria in the fasting state (at time of screening examination)

   • LDL-C: ≥ 140 mg/dL

   • TC: ≥ 220 mg/dL

   • HDL-C: < 40 mg/dL

   • TG: ≥ 150 mg/dL

     • LDL-C value will be directly measured or calculated by the Friedewald formula. Friedewald Formula: LDL-C = TC - HDL-C - TG/5 (When TG value is less than 400 mg/dL) LDL-C value will be directly measured when TG value is 400 mg/dL or greater.

3. Subjects with electrocardiogram (ECG) results showing AV block or with both QTc and QRS width outside the standard values of the ECG laboratory (at time of screening examination)

4. Subjects with alcohol or drug dependence or a history of drug abuse

5. Subjects who have a positive result in an infectious disease test or urine drug test (at time of screening examination)

6. Use of any of the following within the specified period prior to scheduled investigational medicinal product (IMP) administration

   • All other prescription and OTC drugs (within 2 weeks prior to scheduled IMP administration)
   • Alcohol and caffeine-containing products (within 1 week prior to scheduled IMP administration)

7. Use of any other investigational drug within 16 weeks prior to scheduled IMP administration in the present trial

8. Plasmapheresis or plateletpheresis within 2 weeks or whole blood collection (blood donation, etc) cumulatively exceeding 200 mL within 4 weeks, 400 mL within 12 weeks, or 1200 mL within 1 year prior to scheduled IMP administration

9. Subjects whose body weight is less than 50 kg (at time of screening examination)

10. Subjects who are scheduled for examination or treatment at any other hospital or clinic during the trial period

11. Subjects otherwise judged by the investigator or sub investigator to be inappropriate for inclusion in the trial
