  • Participation in a clinical trial of another investigational medicinal product (IMP)within the past month;
  • Treatment with any pain medication since onset of the current edema attack;
  • Treatment with replacement therapy, including C1-INH products (e.g. human C1-INHpreparations), less than 3 days from onset of the current edema attack;
  • Treatment with ACE inhibitors (e.g. Lotensin, Prinivil, Accupril);

Study Description

This Phase II/III study consisted of two parts: A controlled phase and An Open label extension(OLE) phase. The controlled phase describes the double blind part of the study and was intended to evaluate the efficacy of icatibant in decreasing the time to onset of symptom relief compared with placebo for the first treated cutaneous and/or abdominal attack in randomised patients. Patients experienced a laryngeal attack were not randomised, but treated with open label icatibant according to the controlled phase procedures and assessments. The outcome of this group was to be reported descriptively. After treatment of the first attack in the controlled phase, the patients were eligible to enter the OLE phase. In the OLE phase, patients who experienced angioedema attacks severe enough to warrant treatment were to be treated with s.c. icatibant as appropriate until the end of the study.The OLE phase became a modified open label extension where all 56 patients who had been randomised and the last randomised patient had concluded the double-blind phase. The modified open label extension period permitted treatment for patients who were screened and found eligible but did not experience an angioedema attack, or had an attack that was not severe enough to merit treatment while the double blind phase was still ongoing.
