First received: June 7, 2010
Last updated: December 22, 2010
Last verified: December 2010
The purpose of this study is to assess the affect that PF-00232798 has on QT interval. A prolonged QT interval is a risk factor for arrhythmias.

Condition Intervention Phase
Healthy Drug: PF-00232798 Drug: Placebo Drug: Moxifloxacin Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Official Title: A Phase 1, Randomized, Multiple Dose, Placebo And Active Controlled, 4-Way Crossover Study To Evaluate The Effect Of A Multiple Oral Dose of PF-00232798 On Qt Intervals In Healthy Subjects

Further study details as provided by Pfizer:

Primary Outcome Measures:
  • QTc, using Fridericia's correction method (QTcF) at each time point of PF-00232798 and placebo on Day 7. [ Time Frame: 7 days ]

Secondary Outcome Measures:
  • QTcF, or any other appropriate correction method at each postdose time point of moxifloxacin on Day 7 [ Time Frame: 7 days ]
  • QTcB or any other appropriate correction method at each postdose time point of PF-00232798 and placebo on Day 7 [ Time Frame: 7 days ]
  • Pharmacokinetic endpoints for PF-00232798 (Tmax, Cmax, Cτ, and AUClast) [ Time Frame: 7 days ]
  • Safety and toleration assessed by spontaneous reporting of adverse events, vital signs, 12-lead ECG and laboratory safety assessments [ Time Frame: 7 days ]

Enrollment: 44
Study Start Date: July 2010
Study Completion Date: December 2010
Primary Completion Date: December 2010 (Final data collection date for primary outcome measure)
