Heparin Investigation: "Unsettling" Indeed

"We at FDA understand how unsettling this whole situation with heparin is."

That is how FDA Office of New Drugs Deputy Director Sandra Kweder wrapped up FDA's latest media teleconference discussing the agency's investigation into adverse event reports associated with Baxter's heparin multi-dose vials in the US.

Unsettling indeed. We have written previously about the ugly turn the investigation has taken, and things keep getting uglier.

Apart from the adverse reactions and potential shortage of a critical hospital product, the heparin story seemingly confirms everyone's worst fears about globalization (though no one knows for sure, the suspicion is that the adverse events result from problems with the raw material sourced from China), FDA (the agency got confused and didn't inspect the Chinese plant in question), and the overall safety of the drug supply (if we see any more pictures of pig intestines in China we are going to be sick.)

In case you missed the latest news, Baxter has now recalled all remaining supplies of the product, having received assurance that the only other supplier, APP, can meet demand in the US. And FDA has completed its inspection of the Chinese facility. The agency determined that it is no longer manufacturing API and--surprise surprise--that there are some "objectionable" issues with its Good Manufacturing Practices compliance.

FDA is not ready to issue a formal regulatory pronouncement about the Chinese facility. However, it did post the standard inspection report (an FD-483--inset above) on its website.

They say a picture is worth a thousand words. The inspection report probably won't do as much to shake public confidence in the drug supply as images of pig intestines at the start of the heparin production process, but for quality control professionals in industry, it takes just 642 words (allowing for redactions) to paint a devastating portrait of the facility.

Our favorite section:

"The inside surface of large, 'cleaned' [Redacted] tanks ...were very scratched, with unidentified material adhering to the insides and the inverted handles held liquid, which spilled to the bottom of the tank when it was uprighted. There was no written procedure showing that the tanks were dedicated to a particular process step. There was no data collected to verify marker and tape volume markings on the outside of the tanks and, the cleaning method was not validated. It was noted that equipment cleaning tags were made of paper and taped to the piece of equipment unprotected from liquids used in the processing room environments."
One prediction: that will definitely not be the last word on the heparin investigation.

my mother died suddenly from cardiac tamponade, a rare cause of death and no one at the hospital can explain how it happened. She was given Heparin just prior to her death. I wonder if there is any correlation
