Study Description

Brief Summary:

Primary Outcome Measures:

The primary endpoint was the time to onset of symptom relief of the first attack in the double blind phase. H0: λ icatibant/λ tranexamic acid =1 versus H1: λ icatibant/λ tranexamic acid ≠1 Where: λ icatibant refers to the hazard rate under icatibant and λ tranexamic acid refers to the hazard rate under tranexamic acid.

Secondary Outcome Measures:

• Additional efficacy assessments (Time to Almost Complete Symptom Relief)
• Safety and tolerability
• Pharmacoeconomics

Condition or disease	Intervention/treatment	Phase
Hereditary Angioedema	Drug: Icatibant; Drug: Tranexamic Acid; Drug: Oral Placebo; Drug: S.C. Placebo	Phase 3

Detailed Description:

This was a Phase III, randomised, double blind, double dummy, multicentre, controlled,parallel group study of a 30 mg s.c. formulation of icatibant for the treatment of patients with moderate to very severe symptoms of cutaneous and/or abdominal symptoms of HAE.

The study consisted of two parts: controlled phase and OLE phase. For the primary endpoint, Efficacy was determined by evaluating the differences in study outcomes using a Visual Analogue Scale for patients treated with icatibant and tranexamic acid.

Arms and Interventions

Arm	Intervention/treatment
Experimental: Randomized controlled -Icatibant; Subjects received S.C icatibant+ oral placebo Icatibant Form: solution for injection, 3 mL, 10 mg/mL Single dose: 30 mg (3 mL) Placebo Form: hard capsule Single dose: 2 capsules Frequency: 3 x 2 capsules for 2 days, taken orally, 6 to 8 hours apart	Drug: Icatibant; Icatibant: a stable, synthetic decapeptide and specific BK B2 receptor antagonist.; Other Name: Brand name, Firazyr®; Drug: Oral Placebo; hard capsule matched to tranexamic acid; Other Name: Placebo
Active Comparator: Randomized controlled-Tranexamic acid; Subjects received oral Tranexamic acid+ S.C. placebo Tranexamic acid Form: over encapsulated film tablet Single dose: 1000 mg (2 capsules) Frequency: 3 x 2 capsules for 2 days, taken orally, 6 to 8 hours apart Placebo Form: solution for injection, matched to icatibant for injection Single dose: 3 mL Frequency: one subcutaneous injection in the abdominal region	Drug: Tranexamic Acid; over encapsulated film tablet an anti-fibrinolytic agent,is used in some European countries for the treatment of acute oedema episodes and the continuous prophylaxis of HAE.; Drug: S.C. Placebo; solution for injection, matched to icatibant for injection; Other Name: Placebo
Experimental: Controlled Open-label / laryngeal attack; Patients with laryngeal symptoms at the baseline were not randomised but treated with icatibant open label during the controlled phase.	Drug: Icatibant; Icatibant: a stable, synthetic decapeptide and specific BK B2 receptor antagonist.; Other Name: Brand name, Firazyr®
Experimental: Untreated patients at the baseline; 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 controlled phase was ongoing were treated in the open label phase with icatibant	Drug: Icatibant; Icatibant: a stable, synthetic decapeptide and specific BK B2 receptor antagonist.; Other Name: Brand name, Firazyr®

Outcome Measures

Primary Outcome Measures :

1. Time to Onset of Symptom Relief. [ Time Frame: 2 days ]
   The primary efficacy endpoint was Time to onset of symptom relief (TOSR) following treatment with either icatibant or tranexamic acid. The median time to onset of symptom relief for the icatibant group was compared to the the median time to onset of symptom relief for the tranexamic acid group. TOSR was defined as the time between time of injection to time of first documented onset of symptom relief for the three primary symptoms: cutaneous swelling, cutaneous skin, and abdominal pain. The primary symptom was based on the type of attack. For abdominal attacks, the single primary symptom was abdominal pain. For cutaneous attacks, the single primary symptom was either skin swelling or skin pain, whichever was most severe.

Secondary Outcome Measures :

1. Time to Almost Complete Symptom Relief [ Time Frame: 48 hours ]
   Almost complete symptom relief was defined as a score between 0 and 10 mm on the VAS for at least three consecutive measurements for all symptoms.
