Bigger story? The Japanese company marketing Tavneos, Kissei - has told docs to stop using Avacopan WSJ story (Apple News link; apple.news/A8Woi0mr1QIm...)
“Kissei told doctors Friday to stop prescribing the drug to new patients.
The Japanese drugmaker said the 20 deaths occurred in people who had suffered a serious liver “impairment” and attributed 13 of the deaths to a condition, called vanishing bile duct syndrome, marked by the destruction of the ducts that carry bile out of the liver.
Kissei said causal links to Tavneos hadn’t been confirmed in all 20 deaths. Amgen shares were down more than 2% late Friday.
An Amgen spokeswoman said the 20 deaths occurred among more than 8,500 patients treated in Japan, and that some cases involved deaths where a causal link to Tavneos hadn’t been established. She added that no deaths linked to serious liver injury have been reported among the more than 8,000 U.S. patients who have taken the drug.
CSL, which holds the rights to sell the drug outside the U.S. and licensed it to Kissei for sale in Japan, said it “takes all matters of patient safety seriously” and is committed to working with regulators.
“Kissei has begun providing information to healthcare professionals, urging them to refrain from using this drug for new patients and to carefully assess the continuation of treatment for ”
