Last verified: July 2011

Randomised, double-blind, parallel group comparison of four dose levels of V24343 and placebo to study the effect of V24343 on blood pressure and weight in obese subjects.

The primary variables, change in blood pressure (BP) and pulse, will be assessed both by outpatient ambulatory monitoring of vital signs and by regular clinic monitoring.

The efficacy of V24343 will be assessed by measurement of body weight, waist circumference, bioimpedance assessment of body composition and blood glucose.

Assay of plasma concentration of V24343 in blood samples collected at intervals after dosing will be used to assess the pharmacokinetics of V24343.

Other safety assessments comprise routine monitoring of adverse events; concomitant medication; clinical laboratory safety tests, 12-lead electrocardiograms (ECG) and self-completed psychiatric assessments.

Primary Outcome Measures:
  • To examine any effects of V24343 on pulse and blood pressure (vital signs) [ Time Frame: 24-hour on screening and pre-dose on Days 2, 26 and 56. Semi -recumbent and stand SBP , DBP and pulse, in duplicate at each time point. ]

Secondary Outcome Measures:
  • To determine if there is adequate differentiation between doses of V24343 associated with any effect on vital signs and those associated with efficacy (weight loss). [ Time Frame: Body weight and wasit circumference: screen and time-matched to pre-dose on Days -1, 8, 15, 22, 29, 35, 42, 49 and 56. ]

Enrollment: 32

  • be male subjects whose female partners are trying to become pregnant within 3 months after the last dose of study medication
  • have a significant medical condition or a history of such a condition that the Investigator considers should exclude the subject from the study

  • be seropositive for hepatitis B, hepatitis C or human immunodeficiency (HIV) viruses at screening
  • have any medical or social reasons for not participating in the study raised by their General Practitioner/primary care physician
  • have any other condition that might increase the risk to the individual or decrease the chance of obtaining satisfactory data, as assessed by the Investigator
  • have had treatment with any prescription medicine within one month of first dose or any over-the-counter medicines, except for paracetamol, within one week of the first dose
