Fibrogen plunges on murky safety disclosure

 Fibrogen stock plummeted late Tuesday on a murky disclosure for its controversial anemia treatment in chronic kidney disease patients.

While preparing for an advisory committee meeting ahead of potential approval of its drug, roxadustat, Fibrogen (FGEN) said it realized it submitted altered information to the Food and Drug Administration pertaining to the drug's cardiovascular safety.

Now, Fibrogen says the new data suggest roxadustat might not be superior to another drug called epoetin-alfa in lowering the risk of cardiovascular events in some patients.

In late action on the stock market today, Fibrogen stock plunged 23.2% near 26.60. Shares closed the regular session down 2.8% at 34.64.
