Blackburn v. Shire US Inc., No. 20-12258 (11th Cir. 2021)Annotate this Case
Blackburn, who has Crohn’s disease, was prescribed LIALDA, an anti-inflammatory drug specifically aimed at the gut. LIALDA is not FDA-approved to treat Crohn’s, but it is approved to treat ulcerative colitis, Crohn’s “sister” disease. Blackburn was subsequently diagnosed with advanced-stage kidney disease. Blackburn does not claim that Shire, LIALDA’s manufacturer failed to warn of the risk of kidney disease; he and his doctor knew that the drug might impair his kidney function. Blackburn contends that Shire should have more explicitly warned his doctor about how regularly to monitor his kidney function after prescribing LIALDA. He contends that, if LIALDA’s warning label had been better, his physician would have discovered the effect on his kidneys sooner and prevented his injury.
The Eleventh Circuit identified two unsettled, dispositive questions of Alabama law, which it certified to the state’s highest court. May a pharmaceutical company’s duty to warn include a duty to provide instructions about how to mitigate warned-of risks? May a plaintiff establish that an improper warning caused his injuries by showing that his doctor would have adopted a different course of testing or mitigation, even though he would have prescribed the same drug?
