About

The purpose of this study is to determine the pharmacokinetic profile of oral doses of AZD7295 capsules in healthy subjects, and also to assess the effects of food as well as safety and tolerability.

Full description

OBJECTIVES: Primary

To determine the pharmacokinetic profiles of oral doses of AZD7295 capsules administered to healthy subjects To study the effect of food on the pharmacokinetic profiles of oral doses of AZD7295 capsules in healthy subjects To assess the safety and tolerability profiles of oral daily doses of AZD7295 capsules in healthy subjects TYPE AND DESIGN: Part A A phase I, single-centre, double-blind, randomised, placebo-controlled, crossover, food effect study in healthy subjects

Part B A phase I, single-centre, double-blind, randomised, placebo-controlled, ascending dose study in healthy subjects

NUMBER OF SUBJECTS: 16 subjects will take part in a total of 4 treatment periods.

SUBJECT CHARACTERISTICS: Healthy males and females of non-child bearing potential aged 18 to 65 years.

Recruitment will not be balanced for gender or any other variable.

TREATMENT: Part A

Subjects will be randomised to receive AZD7295 or placebo (14 active; 2 placebo) in either the fed or fasted state according to the treatment allocation:

Treatment A: 260 mg (4 x 65 mg) AZD7295 capsules or placebo dosed in the fed state

Treatment B: 260 mg (4 x 65 mg) AZD7295 capsules or placebo dosed in the fasted state

Following dosing of the first two periods there will be a period of interim analysis, during which the pharmacokinetic data will be reviewed in order to determine whether the remaining treatments will be dosed either in the fed or fasted state.

Subjects from Part A will continue into Part B of the study.

Part B

Subjects will be allocated to two groups of n=8 (Group 1 and Group 2) and randomised to receive AZD7295 or placebo (6 active; 2 placebo). Subjects will receive two of the ascending dose treatments in the following order according to group allocation:

Group 1:

Treatment C: 455 mg (7 x 65 mg) AZD7295 or placebo dosed either in the fed or fasted state;

Group 2:

Treatment D: 650 mg (10 x 65 mg) AZD7295 or placebo dosed either in the fed or fasted state;

Group 1:

Treatment E: 650 mg (10 x 65 mg) AZD7295 or placebo, twice a day (q12h) dosed either in the fed or fasted state (total administered dose: 1300 mg);

Group 2:

Treatment F: 650 mg (10 x 65 mg) AZD7295 or placebo, three times a day (q8h) dosed either in the fed or fasted state (total administered dose: 1950 mg).

Safety data and limited PK data will be reviewed by the data review group prior to proceeding to the next dose level.

During the dose escalation phase a maximum of 4 subjects will be dosed per day.

MAIN OUTCOME MEASURES: The primary outcome will be to determine the pharmacokinetic profiles of AZD7295 when dosed in the fed and fasted state and to assess the safety and tolerability of higher daily doses of AZD7295.

GENERAL SCHEDULE: Screening is planned to start in April 2009, with the clinical phase due to be completed by the end of July 2009

Exclusion criteria

  1. Participation in a clinical research study involving investigational drugs or dosage forms within the previous 3 months;

  2. Subjects who have previously been enrolled in this study;

  3. A past or current disease, which as judged by the Investigator, could affect the subject's participation in or the outcome of the study. These diseases include, but are not limited to cardiovascular disease, malignancy, hepatic disease, renal disease, haematological disease, neurological disease, immunological disease and endocrine disease;

  4. Subjects who have ever sought advice from or been referred to a GP or counsellor for abuse or misuse of alcohol, non medical drugs, medicinal drugs or other substance abuse e.g. solvents;

  5. Subjects who admit to any current or previous use of Class A drugs such as opiates, cocaine, ecstasy, lysergic acid diethylamide (LSD) and intravenous amphetamines (Subjects who admit to occasional past use of cannabis will not be excluded as long as they have a negative drugs of abuse test and have been abstinent for at least 12 months;);

  8. Smoking of more than 10 cigarettes per day and the inability to refrain from smoking during confinement;

  9. Females of child bearing potential, as detailed in Section 9.4;

  10. Clinically significant abnormal biochemistry, haematology or urinalysis as judged by the PI (Appendix 1, Section 20);
