Brief Summary:
The purpose of this study is to compare the absorption and blood levels of IX-01 when given as a capsule compared to liquid form, and how food affects the absorption in healthy men.

Official Title: A Randomised, Single-dose, 3-way Crossover Study to Evaluate the Relative Bioavailability of the IX-01 Capsule Formulation Compared With the IX-01 Aqueous Dispersion Formulation, and the Effect of Food on the IX-01 Capsule Formulation, in Healthy Male Subjects
Study Start Date : May 2014

Arm Intervention/treatment
Experimental: IX-01 Capsule while Fasting
Singe oral dose of 800 milligrams of IX-01 as a capsule, while fasting, in 1 of 3 treatment periods
Drug: IX-01
Experimental: IX-01 Aqueous Dispersion while Fasting
Single oral dose of 800 milligrams IX-01 as an aqueous dispersion, while fasting in 1 of 3 treatment periods
Drug: IX-01
Experimental: IX-01 Capsule after Food
Single oral dose of 800 milligrams IX-01 as a capsule, after food, in 1 of 3 treatment periods
Drug: IX-01



Primary Outcome Measures :
  1. Relative Bioavailability (Frel) of a Capsule Compared to a Liquid Formulation of IX-01 While Fasting, as Calculated by a Ratio of Area Under the Plasma Concentration Time Curve From Time 0 to Infinity [ Time Frame: Pre-dose up to 96 hours post dose ]
  2. Relative Bioavailability (Frel) of a Capsule Formulation of IX-01 in the Fed State Compared to the Fasted State, as Calculated by a Ratio of Area Under the Plasma Concentration Time Curve From Time 0 to Infinity [ Time Frame: Pre-dose up to 96 hours post dose ]
  3. Relative Bioavailability (Frel) of a Capsule Compared With a Liquid Formulation of IX-01 While Fasting, as Calculated by a Ratio of Peak Plasma Concentrations [ Time Frame: Pre-dose up to 96 hours post dose ]
  4. Relative Bioavailability (Frel) of a Capsule Formulation of IX-01 in a Fed State Compared to a Fasted State, as Calculated by a Ratio of Peak Plasma Concentrations [ Time Frame: Pre-dose up to 96 hours post dose ]
  5. Area Under the Plasma Concentration Time Curve From Time 0 to Infinity, Following a Single Dose of IX-01 [ Time Frame: Pre-dose and up to 96 hours post dose ]
  6. Peak Plasma Concentration (Cmax) of IX-01 [ Time Frame: Pre-dose and up to 96 hours post dose ]
  7. Time to Peak Plasma Concentration (Tmax) of IX-01 [ Time Frame: Pre-dose up to 96 hours post dose ]
  8. Elimination Half Life (t1/2) of IX-01 [ Time Frame: Pre-dose up to 96 hours post dose ]
  9. Elimination Rate Constant (Kel) of IX-01 [ Time Frame: Pre-dose up to 96 hours post last dose ]
  10. Area Under the Plasma Concentration Time Curve From Time 0 to the Time of the Last Measurable Sample of IX-01 [ Time Frame: Pre-dose to the time of the last measurable sample ]
  11. Concentration of IX-01 in Cerebrospinal Fluid (CSF) After a Single Dose of the Liquid Formulation of IX-01 [ Time Frame: 1, 2, 4 and 6 hours after dosing ]
    Listed by time point of 1, 2, 4, 6 hours post dose


Secondary Outcome Measures :
  1. Number of Participants With One or More Drug-Related Adverse Events (AEs) or Any Serious AEs [ Time Frame: Baseline to study completion (approximately 6 weeks) ]

  • Willingness to give written consent to have data entered into The Over Volunteering Prevention System

Exclusion Criteria:

  • Clinically relevant abnormal history, physical findings, ECG, or laboratory values at the pre-trial screening assessment, including:

    • Lipid and/or liver function test results >1.25 x Upper Limit of Normal (ULN) or other clinical laboratory blood biochemistry test results outside the normal reference range unless discussed and approved by sponsor
