HAE Long-Term Prophylaxis from Ionis Pharmaceuticals.
Dawnzera is an RNA-targeted prophylactic therapy for prevention of HAE attacks. It works by reducing production of prekallikrein — the precursor of plasma kallikrein, which drives bradykinin generation in HAE attacks. Standard dosing is every 4 weeks subcutaneously, with every-8-week dosing as an option for selected patients who maintain attack control. The RNA-targeted mechanism is a newer approach in HAE prophylaxis.
Dawnzera is FDA-approved for the following indications:
Dawnzera is administered as a subcutaneous self-injection every four weeks, with every-eight-week dosing considered for patients who maintain attack control. Patients are trained on technique by an injection nurse.
The manufacturer offers a patient support program — Ionis Patient Services — that can help with insurance navigation, copay assistance for eligible patients, nursing support, and ongoing education. More information is available at https://www.dawnzera.com.
Treatment with Dawnzera is initiated and monitored by Dr. McNeil. Prior authorizations are handled in-house — patients are not asked to navigate insurance approvals on their own. This is a subcutaneous self-administered medication. After prior authorization, the prescription is sent to a specialty pharmacy that ships the medication directly to the patient. A manufacturer-sponsored nurse or office-based training visit is typically arranged for the first dose so patients are confident with self-administration before continuing at home.
