A Phase 1 Study To Evaluate The Pharmacokinetics And Safety Of Three Modified Release And One Immediate Release Formulations Of Tofacitinib (CP-690,550) In Healthy Volunteers

This study has been completed.
Sponsor:
Information provided by (Responsible Party):
Pfizer
ClinicalTrials.gov Identifier:
NCT01499004
First received: November 23, 2011
Last updated: January 11, 2012
Last verified: January 2012
  Purpose
This study will explore the drug behavior and safety following a single dose of three different 22 milligram tofacitinib (CP-690,550) modified-release formulations in 30 healthy volunteers. These formulations will be compared to 10 milligram tofacitinib (CP-690-550) in an immediate-release formulation.

Condition Intervention Phase
Healthy Drug: tofacitinib (CP-690,550) modified-release formulation A Drug: tofacitinib (CP-690,550) modified-release formulation B1 Drug: tofacitinib (CP-690,550) modified-release formulation B2 Drug: tofacitinib (CP-690,550) immediate-release formulation Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: None (Open Label)
Primary Purpose: Basic Science
Official Title: A Phase 1, Randomized, Open Label, Partial Crossover Study To Evaluate The Pharmacokinetics (PK) And Safety Of Three Modified Release (MR) And One Immediate Release (IR) Formulations Of Tofacitinib (CP-690,550) In Healthy Volunteers

Primary Outcome Measures:
  • AUCinf: Area under the plasma concentration-time profile from time 0 exprapolated to infinite time [ Time Frame: 72 hours post dose ]
  • AUClast: Area under the plasma concentration-time profile from time 0 to the last with quantifiable concentration [ Time Frame: 72 hours post dose ]
  • Cmax: Maximum plasma concentration of tofacitinib (CP-690,550) [ Time Frame: 72 hours post dose ]
  • Tmax: Amount of time tofacitinib (CP-690,550) is at maximum plasma concentration [ Time Frame: 72 hours post dose ]
  • t1/2: The time required for one half of the total amount of tofacitinib (CP-690,550) to be removed from the plasma [ Time Frame: 72 hours post dose ]

Secondary Outcome Measures:
  • Frel: Relative bioavailability (Frel) of tofacitinib (CP-690,550) in the modified-release formulations compared to the immediate release formulation [ Time Frame: 24 hours post dose ]

Enrollment: 30
Study Start Date: November 2011
Study Completion Date: December 2011
Primary Completion Date: December 2011 (Final data collection date for primary outcome measure)
