简要总结
HAE is a rare disorder characterized by functional C1 esterase inhibitor deficiency. If not treated adequately, the acute attacks of HAE can be life-threatening and may even result in fatalities, especially in case of swelling of the larynx. This clinical Phase 2/Phase 3 study was designed to provide clinically relevant data on dosing, efficacy and safety in subjects with HAE.
详细描述
For each subject, only a single abdominal or facial attack was treated and evaluated. After receiving treatment, subjects were observed for a minimum of 4 hours, after which they could be discharged from the study center if they reported onset of symptom relief. Starting from 4 hours after treatment, subjects who reported insufficient or no symptom relief could receive a second dose of double-blind treatment (called "rescue medication") as follows: C1-INH 20 U/kg bw for subjects initially receiving placebo, C1-INH 10 U/kg bw for subjects initially receiving C1-INH 10 U/kg bw, and placebo for subjects initially receiving C1-INH 20 U/kg bw.
The study was defined to be successful if the primary outcome measure and at least one of the secondary outcome measures were met in the comparison between the C1-INH 20 U/kg bw group and the Placebo group.

结局指标
主要结局
Time to Start of Relief of Symptoms From HAE Attack
时间窗: Up to 24 h after start of study treatment
The start of symptom relief was determined by subject self-assessment. Time to start of symptom relief was set to 24 hours if the subject received rescue medication (blinded study medication, narcotic analgesics, antiemetics, open-label C1-INH, or fresh frozen plasma) at any time point after the start of study treatment but before start of relief.
次要结局
- Number of Subjects With Worsened Intensity of Clinical HAE Symptoms(Baseline and between 2 and 4 h after start of study treatment)
- Number of Vomiting Episodes(Within 4 h after start of study treatment)
