This study is being performed to investigate the potential for AZD5672 to affect the electrical conduction pathways in the heart. AZD5672 will be compared against a drug (moxifloxacin - a licensed antibiotic) known to have a detectable but safe change on the electrical conduction of the heart.

Condition Intervention Phase
Rheumatoid Arthritis Drug: AZD5672 Drug: Moxifloxacin Drug: placebo Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Triple (Participant, Investigator, Outcomes Assessor)
Primary Purpose: Basic Science
Official Title: A Single-centre, Double-blind, Double-dummy, Randomised, Placebo-controlled, Four-period Crossover Study to Assess the Effect of Single Oral Doses of AZD5672 (600 mg and 150 mg) on QT/QTc Interval, Compared to Placebo, Using Moxifloxacin (Avelox®) as a Positive Control, in Healthy Male Volunteers

Further study details as provided by AstraZeneca:

Primary Outcome Measures:
  • Evaluate time-matched QTcF intervals of single dose AZD5672 600mg compared to placebo. [ Time Frame: Up to 24 hours postdose ]

Secondary Outcome Measures:
  • Evaluate time-matched QTcF Intervals of single dose AZD5672 150mg compared to placebo. [ Time Frame: Up to 24 hours postdose ]
  • To evaluate the change in time matched ECG parameters (QTcB, QTcX, RR, PR and QRS) of single dose AZD5672 600mg and 150mg compared to placebo [ Time Frame: Up to 24 hours postdose ]
  • To further evaluate the safety and tolerability of single dose AZD5672 600mg and 150mg [ Time Frame: Adverse events assessed throughout the whole study. Safety monitoring (BP, safety blood samples and ECG) conducted frequently throughout study and up to 72 hours post dose on treatment visits. ]
