Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of ASP5354 in Healthy Adult Japanese Male Participants

JRCT ID: jRCT2071210026

Registered date:25/05/2021

Basic Information

• Recruitment status: Complete
• Health condition(s) or Problem(s) studied: Laparoscopic/Minimally Invasive Colorectal Surgery
• Date of first enrollment: 02/06/2021
• Target sample size: 12
• Study type: Interventional
• Intervention(s): This study is comprised of 3 parts. Part 1 and Part 2 will be conducted in a parallel manner while Part 3 will be conducted subsequentially. Participants will be admitted to the clinical unit on day -1. After randomization, participants will receive a single intravenous dose of ASP5354 or placebo under fasting conditions followed by a 24-hour in-house blood and urine sampling period. Participants will be residential for a period of 3 days/2 nights. Participants will be discharged from the clinical unit on day 2 on the condition that all required assessments have been performed and that there are no medical reasons for a longer stay in the clinical unit.

Outcome(s)

Primary Outcome

- Adverse Events (AEs)
- Laboratory values
- Vital signs
- Routine 12-lead electrocardiogram (ECG)

Secondary Outcome

Pharmacokinetics (PK) of ASP5354 in plasma:
- Area under the concentration-time curve from the time of dosing extrapolated to time infinity (AUCinf)
- AUC from the time of dosing to the last measurable concentration: (AUClast)
- Maximum concentration (Cmax)
Pharmacokinetics (PK) of ASP5354 in urine:
- Amount of administered dose excreted from the time of dosing to the last measurable point after dosing (Aelast)
- Percentage of administered dose excreted from the time of dosing to the last measurable point after dosing (Aelast%)
- Renal clearance (CLR)

Exclude criteria

1.Participant has received any investigational therapy within 12 weeks prior to screening.
2.Participant has any condition that makes the participant unsuitable for study participation.
3.Participant has a known or suspected hypersensitivity to ASP5354 or any components of the formulation used.
4.Participant has had previous exposure with ASP5354.
5.Participant has any of the liver function tests (alkaline phosphatase [ALP], alanine aminotransferase [ALT], aspartate aminotransferase [AST] and total bilirubin [TBL]) above the upper limit of normal (ULN) on day -1. In such a case, the assessment may be repeated once.
6.Participant has creatinine level outside normal limits on day -1. In such a case, the assessment may be repeated once.
7.Participant has any clinically significant history of allergic conditions (including drug allergies, asthma, eczema or anaphylactic reactions, but excluding untreated, asymptomatic, seasonal allergies) prior to IP administration.
8.Participant has any history or evidence of any clinically significant cardiovascular, gastrointestinal, endocrinologic, hematologic, hepatic, immunologic, metabolic, urologic, pulmonary, neurologic, dermatologic, psychiatric, renal and/or other major disease or malignancy.
9.Participant has/had febrile illness or symptomatic, viral, bacterial (including upper respiratory infection) or fungal (noncutaneous) infection within 1 week prior to day -1.
10.Participant has any clinically significant abnormality following the physical examination, electrocardiogram (ECG) and protocol-defined clinical laboratory tests at screening or on day -1.
11.Participant has a mean pulse <40 or >100 bpm; mean systolic blood pressure (SBP) < 90 or > 140 mmHg; mean diastolic blood pressure (DBP) < 40 or > 90 mmHg (measurements taken in triplicate after participant has been resting in the supine position for at least 5 minutes; pulse will be measured automatically) on day -1. If the mean blood pressure exceeds the limits above, one additional triplicate may be taken.
12.Participant has body temperature < 35.0 degree or >= 37.5 degree on day -1.
13.Participant has a mean corrected QT interval using Fridericia's formula (QTcF) of > 430 msec on day -1. If the mean QTcF exceeds the limits above, one additional triplicate ECG may be taken.
14.Participant has used any prescribed or nonprescribed drugs (including vitamins, oral contraceptives or hormone replacement therapy (HRT) and natural and herbal remedies, e.g., St. John's Wort) in the 2 weeks prior to IP administration, except for occasional use of acetaminophen (up to 2 g/day) and topical dermatological products (including corticosteroid products).
15.Participant has a history of smoking > 10 cigarettes (or equivalent amount of tobacco) per day within 3 months prior to day -1.
16.Participant has a history of consuming > 16 units of alcohol per week within 3 months prior to day -1 (note: 1 unit = 10 g pure alcohol, = 250 mL of beer [5%], 35 mL of spirits [35%] or 100 mL of wine [12%]).
