Shire scores new FDA thumbs-up for HAE drug Cinryze in latest bid to fend off rival CSL

When CSL launched its hereditary angioedema drug Haegarda last year, it played up one big advantage the drug has over Shire’s Cinryze: Haegarda can be injected under the skin, while Cinryze is given twice a week by IV. Now Shire can boast a benefit its drug offers that CSL’s doesn’t: a new FDA approval for use in young children.
