  Purpose
This Study compares two ZD4054 (Zibotentan) doses (10mg and 30mg) with a placebo and a positive control to look at ZD4054 (Zibotentan)'s effect on the ECG of Healthy Volunteer

Condition Intervention Phase
Healthy Drug: ZD4054 Drug: Moxifloxacin Drug: ZD4054 Placebo Drug: Moxifloxacin placebo Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized

Masking: Triple (Participant, Care Provider, Investigator)
Primary Purpose: Basic Science
Official Title: A Phase I, Double-blind, Double-dummy, Placebo-controlled, Randomised, Four-period Crossover Study to Assess the Effects of Single Oral Doses of ZD4054 (Zibotentan) (10mg and 30mg) on QTc Interval Compared to Placebo, Using AVELOX (Moxifloxacin) as a Positive Control, in Healthy Volunteers Aged 18 to 45 Years.

Primary Outcome Measures:
  • to assess the maximum of the mean changes in time-matched QTcX (study specific correction) intervals after ZD4054 (Zibotentan) administration (10mg and 30mg) compared to placebo [ Time Frame: Pre-dose, 0.5hr, 1h, 2h, 3h, 4h, 6h, 8h, 12h, 24h ]

Secondary Outcome Measures:
  • assess the maximum of the mean changes in time-matched QT, QTcB (Bazett's correction), QTcF (Fridericia's correction) and QTcI (subject specific correction) intervals after ZD4054 (Zibotentan) administration (10mg and 30mg) compared to placebo [ Time Frame: Pre-dose, 0.5hr, 1h, 2h, 3h, 4h, 6h, 8h, 12h, 24h ]
  • assess the maximum of mean changes in time-matched QTcX, QT, QTcB, QTcF and QTcI intervals after moxifloxacin administration compared to placebo. [ Time Frame: Pre-dose, 0.5hr, 1h, 2h, 3h, 4h, 6h, 8h, 12h, 24h ]
  • further assess the safety and tolerability of ZD4054 (Zibotentan) by assessment of adverse events (AEs), laboratory variables and vital signs. [ Time Frame: From time of Consent to Last Follow-up Visit ]
