Study summary

The aim of this study is to summarize the data on efficacy and safety of Reduxine administration in the routine clinical practice according to the approved indications.

Read the detailed description

Secondary objectives:

  • to study the structure of the population of patients with the diet induced obesity with body mass index (BMI) 30 kg/m2 or diet induced obesity with BMI ≥27 kg/m2 associated with type 2 diabetes mellitus in respect of comorbidities and concomitant treatment to determine the areas for further investigations.
  • to introduce the elements of control of adverse cardiovascular risks into the routine clinical practice: questionnaire concerning enrollment criteria for Reduxine treatment initiation, algorithm of Reduxine administration and treatment efficacy and safety monitoring (assessment schedule).
  • to assess the effects of the treatment of overweight and obesity with Reduxine on patients' quality of life parameters.

The Time Frame: the follow up of the study patients will be performed during six month to one year. Exception - premature discontinuation from the study.

The scheduled visits of the patients to the investigational centres are: Week0 (inclusion of the patient), Week 2, 4, 6, 8, 10, 12, 16, 20, 24, 36 and Week 48.
