Subjects will either receive Ruconest after the first 2 prodromes or during the last 2 prodromes. 5 clinic visits will occur within 24 hours of a prodrome.

Full description

After screening, subjects will be followed in the study for four consecutive prodromes. For prodromes designed to be treated with Ruconest, the drug will be administered within 12 hours of prodromal onset and prior to the onset of objective selling.
