Patients reported improved QoL with DAWNZERA
DAWNZERA every 4 weeks significantly improved Angioedema Quality of Life (AE-QoL) scores—a validated measure in patients with angioedema1-3
Improvements from baseline in LSM AE-QoL score with DAWNZERA at Week 241

DAWNZERA
improved patient AE-QoL scores MORE THAN 3X beyond the minimum clinically important difference (>6 points)1
