A Study to Assess the Safety, Tolerability and Pharmacokinetics of ASP3700 in Healthy Male Subjects

• Status: Completed
• Trial end date: 2014-10-01
• Target enrollment: 0
• Participant gender: Male

Summary

The purpose of this study is to evaluate the safety, tolerability and pharmacokinetics (PK) of single ascending oral doses of ASP3700 in healthy male subjects. This study will also explore the effect of itraconazole (another drug) on the PK of ASP3700, as well as to evaluate the safety and tolerability of ASP3700 alone and in combination with itraconazole in healthy male subjects.

• Lead Sponsor: Astellas Pharma Europe B.V.
• Treatments: Hydroxyitraconazole; Itraconazole

Criteria

Inclusion Criteria:

• Subject has a body mass index range of 18.5 - 30.0 kg/m2. The subject weighs at least 50 kg.

• Subject and his female spouse/partners who are of childbearing potential must be using highly effective contraception consisting of 2 forms of birth control (1 of which must be a barrier method) starting at screening and continue throughout the clinical study period and for 90 days after the final study drug administration.

• Subject must not donate sperm starting at screening and throughout the clinical study period and for 90 days after the final study drug administration.

Exclusion Criteria:

• Subject has a known or suspected hypersensitivity to ASP3700 (parts 1 and 2) or itraconazole (part 2 only) or significant adverse reactions to historical cannabinoid use or any components of the formulations used.

• Subject has any of the liver function tests (aspartate aminotransferase [AST], alanine aminotransferase [ALT], alkaline phosphatase, gamma-glutamyl transaminase, total bilirubin [TBL]) above the upper limit of normal (ULN). In such a case the assessment may be repeated once (upon admission to the clinical unit).

• Subject has a history of a suicide attempt or suicidal behavior. Any recent suicidal ideation within the last 3 months or who are at significant risk to commit suicide, as judged by the Investigator using the C-SSRS (a level of 4 or 5) at screening or upon admission to the clinical unit.

• Subject has any clinically significant abnormality following the Investigator's review of the physical examination, ECG and clinical study protocol-defined clinical laboratory tests at screening or upon admission to the clinical unit.

• Subject has a pulse rate < 40 or > 90 beats per minute; mean SBP > 140 mmHg; mean DBP > 90 mmHg (vital signs measurements taken in triplicate after subject has been resting in supine position for 5 minutes; pulse rate will be measured automatically) upon admission to the clinical unit.

• Subject has a mean corrected QT interval using Fridericia's formula (QTcF) interval > 430 ms at day -1. If the mean QTcF exceeds the limits above, 1 additional triplicate ECG can be taken.

• Subject has a history of smoking more than 10 cigarettes (or equivalent amount of tobacco) per day within 3 months prior to admission to the clinical unit.

• Subject has a history of drinking more than 21 units of alcohol per week (1 unit = 10 g pure alcohol = 250 mL of beer [5%] or 35 mL of spirits [35%] or 100 mL of wine [12%]) within 3 months prior to admission to the clinical unit.

• Subject has consumed grapefruit, grapefruit-containing products or Seville orange-containing products within 72 hours prior to admission to the clinical unit.
