A study in healthy volunteers to determine whether different drugs metabolised by the liver have any effects on how NRL972 is processed within the body.

Condition Intervention Phase

Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Pharmacokinetics Study
Intervention Model: Crossover Assignment
Masking: Open Label
Primary Purpose: Diagnostic
Official Title: A Single-Centre, Open, Controlled, Randomised Cross-Over Study in Healthy Male and Female Volunteers to Evaluate the Pharmacokinetics of Cholyl-Lysyl-Fluorescein (NRL972) in the Presence of Medication-Induced Changes in Cytochrome P450 or Biliary Transporter Proteins.

Primary Outcome Measures:
  • Total clearance by non-compartmental analysis. Apparent terminal disposition half-life t½ by non-compartmental analysis [ Time Frame: Up to 6 hours post dose ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Non-compartmental PK-analysis based on the extensive profile (up to last quantifiable data point), the 'short' profile (over the first hour after injection), and the two-point profile based on selected data-pairs over the 1st hour after dosing [ Time Frame: Up to 6 hours post dose ] [ Designated as safety issue: No ]

Enrollment: 12
Study Start Date: June 2006
Study Completion Date: August 2006
Primary Completion Date: July 2006 (Final data collection date for primary outcome measure)
