New Asthma Drug 'Zoe' Offers Hope and Concerns for Patients

A new drug, Zoe, is being used in Britain to prevent fatal asthma attacks, potentially saving 1400 lives annually. Costing 300 pounds per injection, it is administered bi-weekly. Fiona de la Bean, who lost her mother to asthma, calls Zoe her miracle drug. Xolair, the active component, blocks antibodies that cause allergic asthma. Fiona, once unable to be near animals or exercise, fears losing access to Zoe due to its high cost, having experienced life without asthma.
