A Combined Single and Multiple Ascending Dose Study of ASP6858 in Healthy Subjects
- Registration Number
- NCT02359032
- Lead Sponsor
- Astellas Pharma Europe B.V.
- Brief Summary
The purpose of this study is evaluate the safety and tolerability of single and multiple ascending oral doses of ASP6858. This study will also evaluate the pharmacokinetics (PK) of ASP6858 and its metabolites as well as the effect of food to the PK of ASP6858. The study will also evaluate the pharmacodynamics of ASP6858.
- Detailed Description
This study has 2 parts: Part 1 is a placebo-controlled, single ascending dose study where male only subjects will be residential for 5-8 days (Part 1 will also include an open-label, food effect section); and Part 2 is a placebo-controlled, randomized, 2-way crossover, multiple ascending dose study where male and female subjects will be residential for 14-17 days for each treatment period. There will be a washout period between the 2 periods in Part 2.

- Subject uses any prescribed or nonprescribed drugs (including vitamins, natural and herbal remedies, e.g., St. John's Wort) in the 2 weeks prior to study drug administration, except for occasional use of paracetamol (up to 2 g/day) and except for use of contraceptives or hormone replacement therapy.
- 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 (in part 2: first admission).
- Subject has a history of drinking more than 21 units (male subjects) or 14 units (female subjects) 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 (in part 2: first admission).
- Subject uses any drugs of abuse within 3 months prior to admission to the clinical unit (in part 2: first admission).
- Subject uses any inducer of metabolism (e.g., barbiturates, rifampin) in 1 month prior to admission to the clinical unit (in part 2: first admission).
- Subject had significant blood loss, donated 1 unit (500 mL) of blood or more, or received a transfusion of any blood or blood products within 60 days or donated plasma within 7 days prior to admission to the clinical unit (in part 2: first admission).
- Subject has a positive serology test for hepatitis B surface antigen, hepatitis A virus antibodies (immunoglobulin M), hepatitis C virus antibodies or antibodies to human immunodeficiency virus type 1 (HIV-1) and/or type 2 (HIV-2) at screening.
- Subject participated in any clinical study or has been treated with any investigational drugs within 3 months or 5 terminal half-lives, whichever is longer, prior to screening.
- Subject is unable to communicate, read and understand English, or has any other condition which, in the investigator's opinion, makes the subject unsuitable for clinical study participation.
- Subject is an employee of the Astellas Group, a Clinical Research Organization or other vendor involved in the clinical study.
