The median time to onset of symptom relief with 10 U/kg (1.2 h) was only slightly shorter than with placebo (1.5 h; p=0.2731). The reduction in median time to onset of symptom relief was more pronounced for severe attacks (0.5 h with 20 U/kg vs 13.5 h with placebo) than for moderate attacks (0.8 h with 20 U/kg vs 1.3 h with placebo) The recommended dose of in the treatment of acute HAE attacks is therefore 20 U/kg Craig et al. Allergy 2011 (I.M.P.A.C.T.2) Prospective, openlabel, uncontrolled, multicentre extension study of I.M.P.A.C.T.1 ITT=57 (Total of 1085 HAE attacks in 57 patients were treated with ) Single IV infusion of 20 U/kg for each attack (including laryngeal) Median duration of treatment = 24 months (range 0 51) Patients received for median of 7 attacks (range 1 184) Median time to onset of symptom relief was 0.46 h (28 min, 95% CI= ; range= ). Individual average time to onset of symptom relief was <1 hr in 51/57 (89.5%) patients. Median time to complete resolution of HAE symptoms was h (95% CI= ; range= ) and was shortest for laryngeal attacks (5.79 h, 95% CI= ; range= ) Individual average time to compete resolution of HAE symptoms was <24 h in 41/57 (71.9%) patients. 20 U/kg was sufficient in 1073 of 1085 attacks (99%). In 12 cases (1%) additional doses, up to a total of 60 U/kg per attack, were administered. Zuraw et al.

The study population comprised 113 subjects (aged 2 80 years); 101 received for an acute attack 1,000 U for attacks of angioedema at any anatomic location. Median time to the onset of relief during the first attack was 45 min. None of the 84 laryngeal attacks required intubation. The number of attacks with unequivocal relief of the defining symptom within 1 and 4 hours after the first dose was 412 (68%) and 529 (87%), respectively. Of the 101 patients treated for an attack during the study period; 80 achieved unequivocal relief of their first attacks within 4 hours after dosing with the study medication (response rate: 79%).

Median time between start of treatment and onset of symptom relief was 0.25 h (15 min, 95% CI h; range h). All attacks were treated successfully. Onset of relief was reported within 1 h of start of treatment, in 95% of all attacks, and time to onset of relief was <0.75 h (45 min) in 85% of patients. Median time to complete symptom resolution was 8.25 hours (95% CI h; range h) when analysed by attack, and 5.87 h (95% CI h; range h) when analysed per patient. Riedl et al.

In the I.M.P.A.C.T.2 study, the median time to onset of symptom relief in paediatric patients was similar to that for adults (0.49 h vs 0.45 h), as was the median time to complete resolution of symptoms (14.1 h in the paediatric group vs 15.9 h in adult patients). Lumry et al.

The median time to the start of unequivocal relief in the acuteattack treatment study (n = 12) was 30 min with, compared with 2 hours for placebo.

HAE attack frequency increased in 39/82 (47.6%) full term pregnancies, clinical signs decreased in 27/82 (32.9%) and 16/82 (19.5%) pregnancies had no influence on HAE. was effective in all instances and no adverse effects were observed. Symptomatic improvement of all types of attack consistently occurred within min of administration. Worsening of symptoms did not occur. Every woman treated with delivered a healthy neonate (disregarding inheritance of HAE). Baker et al.

For acute treatment, Cinryze at 1000 U was administered IV followed by a second 1000 U dose 60 min later, if necessary. Of the 16 unique subjects, 13 subjects delivered 14 healthy neonates (including 1 set of twins), 2 subjects had adverse foetal outcomes deemed unrelated to by investigators, and 1 subject s outcome was unknown.

Median duration of all 20 patients on home therapy was Median time from initial signs of an attack (or oedema symptoms) to start of treatment was significantly shorter with home therapy (15 min) than with previous physician based therapy (67.5 min). Median time from start of treatment to initial symptom relief was significantly shorter with home therapy (40 min) than with Page 5

Cumulatively the 20 patients had received home therapy for 74.1 patient years, during which approximately 2,400 treatments were administered previous physician based therapy (60 min). Mean number of days in hospital was significantly shorter with home therapy than with previous physician based therapy (0.11 days/year vs 3.8 days/year, respectively; p=0.008). The occurrence of laryngeal attacks decreased on home therapy (only 2 patients had laryngeal attacks). All attacks were treated successfully with administered as home therapy. Bygum et al Eur J Dermatol (Self admin and QoL) QoL study ITT=7 All patients registered at Odense Hospital with HAE attacks requiring emergency department administration of (Berinert ) more than once a month were offered to be taught selfadministration. Patients were trained to selfadminister IV on demand After training, all patients were able to treat severe angioedema attacks. Mean DLQI scores decreased from 12.6 (standard deviation [SD]=4.65) before home therapy to 2.7 (SD=1.38) after therapy (p<0.001), a clinically significant 9.9 unit (79%) reduction. Mean SF 36 scores increased significantly for all parameters after home therapy; increases ranged from 13.6% for 'physical function' (p=0.0153) to 96.4% for 'role physical' (p<0.0001). Home therapy resulted in significantly improved QoL and reduced use of emergency services. Kreuz et al. Transfusion 2009 (HAE patients refractory to danazol prophylaxis and QoL) data on efficacy, safety and QoL data associated with pdc1 INH (Berinert ) use prospectively collected and compared with retrospective data on danazol ITT=22 PK data in 15/22 (68.2%) Aged >18 years, with HAE who discontinued longterm prophylaxis with danazol due to lack of efficacy, intolerability and/or severe side effects Based on documented attack intervals and consumption per attack, an individual treatment regimen was prepared for each patient. Usual dose of was 500 to 1000 U up to twice a week. All patients trained on selfinfusion. The change from danazol treatment to IRT with resulted in a median decrease of 43 attacks per year (p<0.001) and decrease of laryngeal attacks from 24 per year to 0. Total QOL score increased from 12.5 (95% CI, 10 18) with danazol to 48.5 (95% CI, 45 57; p<0.001) with IRT. Page 6

In 2 cases of thrombosis causality was assessed as unlikely. The other 14 cases of thrombosis occurred during off label use of the product, in cardiac surgery involving substantially higher doses than indicated in the label. The most commonly reported AEs in patients receiving 20 U/kg were nausea, abdominal pain, dysgeusia, peripheral oedema, vomiting, pain, and muscle spasms. was well tolerated.

Three patients reported 4 TEAEs considered related to. Of these, 2 events were possibly related (injection site pain and rash) and 2 (sinusitis and joint swelling) were of unknown relationship to. Thirteen serious TEAEs were experienced by 6 patients (5%), but all were considered unrelated to the study drug. There was no evidence of human immunodeficiency virus or viral hepatitis transmission or detection of clinically relevant anti C1 INH antibodies Treatment with was generally well tolerated in all patient groups (including children and pregnant/nursing women). Administration of C1 INH was not associated with transmission of viruses or development of autoantibodies irrespective of treatment duration.

No treatment related AEs were reported before, during or after pregnancy. No still births or spontaneous abortions or drug related abnormalities of children were reported. Viral transmission did not occur either in mothers or in neonates.
