§ In Month 1, a loading dose of 400 mg (2x injections) is required.1 ANDEMBRY® may be self-administered only after training by a healthcare professional.1

THE FIRST AND ONLY
FXIIa INHIBITOR FOR HAE1,2
Factor XII is the first protein activated in the contact activation pathway.1,4,5
Factor XIIa plays a key role in HAE attack development by converting prekallikrein to kallikrein, leading to the release of bradykinin.4,5
ANDEMBRY® blocks the function of FXIIa, thereby blocking the conversion of prekallikrein to kallikrein and the subsequent release of bradykinin.1

STUDY DESIGN¶2,7
01/2021 – 06/20221,2
This was an international Phase 3 study conducted across 7 countries: Canada, Germany, Hungary, Israel, Japan, the Netherlands, and the USA. The study included 58 adults and 6 adolescent patients (≥12 years old).


¶ Primary endpoint: investigator-assessed time-normalised number of HAE attacks (number of HAE attacks per month) during the 6-month treatment period (Day 1 to 182). Three secondary endpoints tested in the following hierarchical order: percentage reduction in number of HAE attacks per month vs. placebo (Day 1 to 182); number of attack-free subjects (defined as 100% reduction in attacks vs. baseline) through to Day 91; percentage of patients rating therapy as “good” or “better” with SGART at Day 182. For full patient demographics and inclusion/exclusion criteria, see: Craig J, et al. Lancet. 2023; 401(10382):1079–1090; ClinicalTrials.gov, NCT04656418.2
|| Three patients in placebo arm discontinued the study. One patient discontinued because of lack of efficacy, and two patients withdrew because of HAE attacks.

VANGUARD: ONGOING ASSESSMENT OF
LONG-TERM EFFICACY AND SAFETY OF ANDEMBRY®8
The VANGUARD phase 3 OLE trial aims to evaluate the long-term efficacy and safety of ANDEMBRY® for HAE prophylaxis.8
The trial population includes patients with HAE who participated in the previous phase 2 and 3 trials on ANDEMBRY®, alongside newly enrolled patients.8
Results presented are taken from the latest interim data (cut-off: February 13, 2023; n=161). Median (IQR) treatment exposure was 13.8 months (11.9–16.3 months).8
STUDY DESIGN¶8
03/2021 – 02/2023
This is an international Phase 3 OLE study conducted across 14 countries (Australia, Canada, Czechia, Germany, Hong Kong, Hungary, Israel, Japan, the Netherlands, New Zealand, Russia, Spain, Taiwan, and the USA)


Data presented reflects an interim analysis with a data cut off date of 13 February 2023.
¶The primary endpoint was TEAEs in patients with C1 inhibitor deficiency/dysfunction. For full patient demographics and inclusion/exclusion criteria, see Reshef A, et al. Allergy. 2025; 80:545–556; ClinicalTrials.gov, NCT04739059.8
#Newly enrolled ANDEMBRY® patients were given a loading dose of 400 mg in Month 1.
