Study Evaluating the Pharmacokinetic Profile of Novel Formulations of RHUDEX®

NCT01500122 | Completed Phase 1

• 1 other identifier: CT 5004
• Study Type: interventional
• Target: 12
• Locations: 1 country
• Sites: 1

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

Outcome Measures

Primary Outcomes (1)

• PK blood samples

  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

  taken predose, 0.5 h - 1 - 2 - 3 - 4 - 5 - 6 - 7 - 8- 12- 24 -48 - 72 hours after dosing

Interventions

RhuDex DRUG

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.
