Clinical Trial Summary

The study will be conducted at a single site in the Canada, Quebec. Participants will be recruited from the bariatric surgery clinic and will be required to be either, waiting for sleeve gastrectomy surgery (n=12, restrictive bariatric surgery, Group 1) or Roux-en-Y gastric bypass (n=12, mixed bariatric surgery, Group 1), or had underwent Roux-en-Y gastric bypass 12 ± 3 months ago (n=12, Group 2). Participants in Group 1, edoxaban pharmacokinetic and pharmacodynamics will be evaluated before and 48 ± 5 hours after bariatric surgery (sleeve gastrectomy and Roux-en-Y gastric bypass). Participants in Group 2, edoxaban pharmacokinetic and pharmacodynamics will be evaluated only once, at 12 ± 3 months following their Roux-en-Y gastric bypass. All participants will be received single oral doses of 60 mg edoxaban at each pharmacokinetic and pharmacodynamics evaluation.

Description:

Screening visit (Group 1 and 2: visit 1) // Group 1: Screening will take place within 3 to 4-months window before bariatric surgery. Group 2: Screening will take place within 1-months window approximately 12± 3 months after bariatric surgery. Informed consent will be obtained from the subject prior to performing any of the screening assessments. The following activities and/or assessments will be performed at/during Screening: Informed consent, Inclusion/exclusion criteria, Medical history, Concomitant medications, Physical examination, including height, weight, and body mass index (BMI), Blood and urine samples, 12-lead ECG, Vital signs. Pharmacokinetic (PK) and pharmacodynamics (PD) visit Group 1: PK and PD visit will take place after the screening visit and within 3-months window before bariatric surgery as well as 48 hours after bariatric surgery. Group 2: PK and PD visit will take place after the screening visit and within 1-months window after bariatric surgery (12± 3 months). On PK and PD visit, the following procedures will be performed: Vital signs, ECG, Concomitant medications, Edoxaban dosing (before 8:00 AM), Pharmacokinetics (PK) and Pharmacodynamics (PD) blood draws (predose, 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 12 and 24 hours), Post dose fasting and water restrictions, as appropriate, Adverse event (AE) monitoring. Follow-up 1 - Group 1 and Group 2: Follow-up 1 will take place onsite 24 hours after PK and PD visits. On follow-up 1, the following procedures will be performed: PK and PD blood draws, Concomitant medications, AE monitoring. Follow-up 2 - Group 1 and Group 2: Follow-up 2 will be a phone contact and will take place 7 days after PK and PD visits. On follow-up 2, the following procedures will be performed: Concomitant medications, AE monitoring.

7. Subjects must agree to abstain from food and beverages containing grapefruit, grapefruit juice, cranberry juice, lime, pomelo, marmalade and Seville oranges from 10 days before each study visit with PK and PD evaluation.

8. Absence of clinically significant deviations from medical history, physical examination and 12-lead ECG, as deemed by the Investigator, prior to enrollment.

9. Subject must have sinus rhythm on the 12-lead ECG at each study visit with PK and PD evaluation.

10. Has given written informed consent prior to participating in the study.

11. Able to understand and willing to comply with all study requirements, and willing to allow the collection of all blood specimens.

12. Normal coagulation values from INR (< 1.2).

Exclusion Criteria:

1. History or current evidence of clinically significant cardiac, hepatic, renal, pulmonary, endocrine, neurologic, infectious, gastrointestinal, hematologic, or oncologic disease as determined by screening medical history, physical examination, or 12-lead ECG.

2. Subjects with QTcF interval duration > 450 msec for males and >470 for females.

3. Subjects with abnormal waveform morphology on any of the ECGs at the screening that would preclude accurate measurement of the QT interval duration.

4. Subjects with a resting systolic (treated) blood pressure > 159 mmHg or < 90 mmHg or a diastolic blood pressure > 95 mmHg or < 50 mmHg.

5. History of malignancy.

6. Subjects who have had a clinically significant illness within 4 weeks prior to the first dose.

7. Subjects who have used any drugs or substances known to be strong inhibitors or strong inducers of CYP 3A4/5 enzymes or P-gp within 28 days prior to the first dosing.

8. Subjects with history of major bleeding, major trauma, or major surgical procedure of any type within 6 months of dosing.
