To Assess the Effect of Administration of 2 Formulation of AZD3241 on Blood Concentration in Healthy Volunteers

To evaluate the pharmacokinetics of AZD3241 following multiple administration of 2 new, different extended release formulations of tablets of AZD3241 (300 mg), in relation to the 100 mg extended release tablet used in a previous study and potential food interaction. The safety and tolerability of AZD 3241 will also be investigated as a secondary objective. In addition to these a number of exploratory objectives will be investigated with blood sampling.

Treatment and study plan

AZD3241 ER formulation 1

Drug

Oral tablets, 100mg bd on Day 1 to Day 2, 200mg bd on Day3, 300mg bd on Day 4 to Day7 and 300mg Once daily on Day 8 with High Fat Breakfast

Placebo

Drug

Placebo will be administered with the same intervention scheme as intervention 1 and 2

AZD3241 Alternative titration scheme with formulation 1 or 2

Drug

50 mg oral dose bd on Day 1, 100 mg oral dose bd on Day 2 and 3, 200 mg oral dose bd on Day 4, 300 mg oral dose bd on Day 5 to 7 and 300 mg once in the morning on Day 8

Other names: This titration scheme will only be used if ER formulations 1 or 2 are not well tolerated

Primary outcomes

  1. AUC(0-12),ss: Area under the plasma concentration-time curve from time zero to the end of the 12-hour dosing interval at steady state.

    Time frame: Day 1 until 24 hours post last dose (administered on the morning of Day 8)

  2. AUC(0-12),ss/DN: Area under the plasma concentration-time curve from time zero to the end of the 12-hour dosing interval at steady state observed with the 300 mg ER formulations normalised to a 100 mg dose of AZD3241

    Time frame: Day 1 until 24 hours post last dose (administered on the morning of Day 8)

  3. Css,max: Observed maximum plasma concentration at steady state.Css,max/DN Observed maximum plasma concentration at steady state observed with the 300 mg ER formulations normalised to a 100 mg dose of AZD3241.

    Time frame: Day 1 until 24 hours post last dose (administered on the morning of Day 8)

  4. Css,min: Observed minimum plasma concentration at steady state.Css,min/DN Observed minimum plasma concentration at steady state observed with the 300 mg ER formulations normalised to a 100 mg dose of AZD3241.

    Time frame: Day 1 until 24 hours post last dose (administered on the morning of Day 8)

  5. Css,av: Average plasma concentration during the 12-hour dosing interval at steady state calculated as follows: AUC(0-12),ss/12 h.

    Time frame: Day 1 until 24 hours post last dose (administered on the morning of Day 8)

  6. Description of fluctuation at steady-state [(Css,max-Css,min)/Css,av]

    Time frame: Day 1 until 24 hours post last dose (administered on the morning of Day 8)

  7. AUC(0-t),ss: Area under the plasma concentration-time curve from time zero to the last quantifiable time point.

    Time frame: Day 1 until 24 hours post last dose (administered on the morning of Day 8)

  8. λz,ss: Terminal elimination rate constant at steady state.

    Time frame: Day 1 until 24 hours post last dose (administered on the morning of Day 8)

  9. t½λz,ss: Half-life of terminal elimination phase at steady state.

    Time frame: Day 1 until 24 hours post last dose (administered on the morning of Day 8)

Secondary outcomes

  1. Description of the safety and tolerability profile in terms of Adverse Events of 8 days of administration of AZD3241, up to steady state (300 mg twice daily), of 2 new, different extended release tablets of AZD3241 (300 mg), including initial titration.

    Time frame: Day 1 to Day 8
