Omontys Recalled Due to Reports of Hypersensitivity Reaction

On Saturday, the FDA announced that all lots of Omontys are being recalled due to postmarketing reports of hypersensitivity reactions. In some cases, patients have suffered from anaphylaxis, which is potentially fatal allergic reaction in which the throat sometimes closes. According to the agency’s safety notification, 0.02 percent of 25,000 patients have had a fatal reaction to the Omontys. The FDA notified healthcare professionals about the recall yesterday, stating that it had received 19 reports of anaphylaxis, Reuters reports. Howard Sklamberg, head of the compliance office at the FDA’s Center for Drug Evaluation and Research, stated that “Due to the severity of the public health risk, we want to be certain that healthcare providers stop using Omontys,”

Omontys is administered intravenously to help treat anemia in patients with chronic kidney disease undergoing dialysis. The reported hypersensitivity reactions occur within 30 minutes after receiving the injection.

Bloomberg reports that after the recall, Affymax fell as much as 87 percent. Previously, the California-based company had gained 61 percent in the past year. On Saturday, shares fell to $2.97 and then to $2.14.
