Brief Summary:

The primary objectives of the study are:

  • To compare the pharmacokinetic profiles of RhuDex administered as two novel oral formulations
  • To identify the lead formulation and optimise the pharmacokinetic profile by modifying the quantitative composition of that formulation
  • Optional: To assess the intravenous pharmacokinetics of RhuDex following administration of an IV microtracer of [14C]RhuDex

Condition or disease Intervention/treatment Phase
Formulation Finding Drug: RhuDex Phase 1

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 12 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Official Title: An Open-label, Non Randomized Monocentric Phase I Study Evaluation the Pharmacokinetic Profile of Novel Formulations of RHUDEX®
Study Start Date : December 2011
Actual Primary Completion Date : March 2012
Actual Study Completion Date : June 2012

Intervention Details:
  • Drug: RhuDex

    Part 1:

    Regimen A: Rhudex Formulation in Labrafac/ Gelucire Regimen B: Rhudex Formulation in Labrafac/ Aerosil single dose

    The formulation platform (A or B) that shows the best potential to achieve the target PK profile and shows acceptable safety and tolerability will be progressed into part 2 of the study. The purpose of part 2 is to optimize the selected formulation platform. This will be achieved by administrating up to four different formulation compositions.

Primary Outcome Measures :
  1. PK blood samples [ Time Frame: taken predose, 0.5 h - 1 - 2 - 3 - 4 - 5 - 6 - 7 - 8- 12- 24 -48 - 72 hours after dosing ]
    All target PK evaluations will be made on the basis that the optimal plasma PK profile will be characterised by a plasma Cmax < 5000 ng/mL, an elimination half-life of > 8h and a C(last) (24h) of around 800-1000 ng/mL. Formulations will explicity not be selected based on determinations of Cmax or AUC(0-inf) alone
