This will be an open label, sequential study of midazolam (dose 5 mg orally) followed by midazolam (5 mg orally) given after dosing with OC000459 100 mg twice daily for 6.5 days. Twenty subjects will be included to ensure at least 16 subjects with analysable PK data. PK sampling for midazolam and 4-hydroxymidazolam plasma concentrations will continue for up to and including 24 hours after dosing with midazolam on both occasions.

Drug: OC000459
Phase 1

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Diagnostic
Official Title: An Open Label Balanced Study in Healthy Subjects to Evaluate the Potential for Cytochrome P 450 3A4 Induction by Oral OC000459 Using Oral Midazolam as a Probe

Further study details as provided by Oxagen Ltd:

Primary Outcome Measures:
  • Ratio of exposure of midazolam and 4-hydroxymidazolam (without/with exposure to OC000459) as measured by plasma AUC0-t and Cmax for midazolam and its active metabolite 4-hydroxymidazolam. [ Time Frame: 6.5 days ]

Secondary Outcome Measures:
  • Additional PK parameters of midazolam and its active metabolite 4-hydroxymidazolam [ Time Frame: 6.5 days ]
  • Safety and tolerability of OC000459 [ Time Frame: 6.5 days ]
