The Centers for Disease Control and Prevention (“CDC”) recently issued a final report in the New England Journal of Medicine (“NEJM”) that confirms a definite link between the man-made contaminant found in heparin, (i.e. over-sulfated chondroitin sulfate, [“OSCS”]) and the patients who experienced reactions. Blossom, David, etc., “Outbreak of Adverse Reactions Associated with Contaminated Heparin,” N. ENGL. J. MED. 359:25, 2674-2684 (December 18, 2008), (available at http://content.nejm.org/cgi/content/full/NEJMoa0806450.)

The CDC was the first to investigate suspected reactions among hospital patients given heparin in November of 2007. Before the contaminant was discovered, the CDC collected data on possible reactions occurring from November 19, 2007 through January 31, 2008 that met its case definition (i.e. development of symptoms within one hour after administration of heparin or the initiation of a hemodialysis session). (In its report, the CDC explained that it used this early case definition as an attempt to reduce misclassification, but recognized that in light of what is being discovered about the contaminate, “some true cases may have been misclassified as noncases.”)

The study did not report or investigate the long term effects of contaminated heparin, the cumulative effect of receiving multiple contaminated doses, delayed onset of symptoms, or the contaminate’s effect on other conditions such as heparin induced thrombocytopenia (“HIT”). Instead, the report simply confirmed that the “reported clinical features” of the limited cases it investigated “further support the conclusion that contamination of heparin with OSCS was the cause of the outbreak.”

On Monday, Chinese health officials raised the total number of infants sickened by Sanlu brand milk powder to more than 1,200. (09/15/08 USA TODAY, “Tainted Milk Sickens More than 1,200 Babies in China.”)

The formula was spiked with the industrial chemical, melamine, a contaminate that causes kidney stones (which are otherwise rare in infants). (Id. See also 9/12/08 FDA PRESS RELEASE, “FDA Issues Health Information Advisory on Infant Formula.”) Like the Heparin scandal, the contamination was intentional and a result of corporate greed. Specifically, Chinese investigators say melamine was added to make the milk seem higher in protein and thus, fool quality tests after water was added to fraudulently increase the milk's volume. (Id.)

Unlike the Heparin tragedy, however, it appears that Americans might have missed this latest batch of contaminated products manufactured in China. The FDA has indicated “that there is no known threat of contamination” as “no Chinese manufacturers of infant formula have fulfilled the requirements to sell infant formula in the United States.” (9/12/08 FDA PRESS RELEASE, “FDA Issues Health Information Advisory on Infant Formula.”) Yet, the FDA has not completed its current investigation as to whether or not infant formula manufactured in China is being sold in specialty markets which serve the Asian community. (Id.)

Regardless, this latest contamination is another example of why drugs and other products manufactured in poorly regulated foreign countries cannot be blindly accepted as pure. It should continue to serve as a warning to large U.S. companies who buy these cheaper products and pass them on to the unsuspecting American public…A warning, which unfortunately, was ignored by the big drug company, Baxter, in the heparin disaster that killed numerous Americans.

Today the Chicago Tribune reported that the FDA has only been able so far to "conclusively link" three fatalities to contaminated heparin manufactured by Baxter. (07/30/08 Chicago Tribune: Heparin Taint Tied to Deaths.)

According to the article, in an interview Tuesday with the Tribune, the FDA said it completed its review of 93 death reports related to heparin that the agency received from January 1 to March 31, 2008. (07/30/08 Chicago Tribune: Heparin Taint Tied to Deaths.) Of the 10 reports of death from severe shock known as anaphylaxis or hypotension, three of those could be traced to lot numbers of Baxter products that tested positive for oversulfated chondroitin sulfate (“OSCS”). Heparin lot numbers were not known for the other seven deaths from anaphylaxis or hypotension, so the FDA could not determine whether those 7 patients received heparin contaminated with the substance.

Of the remaining 83 reports, 13 were described as "potential complications of heparin use" such as bleeding; and 25 cases were due to causes unrelated to heparin use such as pneumonia, sepsis and kidney failure. (07/30/08 Chicago Tribune: Heparin Taint Tied to Deaths.) In the remaining 45 deaths, FDA spokeswoman Janet Woodcock stated, "clinical information in the adverse-event reports is insufficient to specify the cause of death with clinical certainty,” and that the FDA was missing information from providers or others who filled out the reports to make an adequate determination. She also added, "While some of these [reports] appear definitely related [to contaminated heparin] many are still in the gray zone…We have looked over all of these death reports and a number of them were probably not related to the contaminated heparin."

While it is good that the FDA has finally conclusively linked some of the deaths, many questions are still unanswered. The top five questions that immediately jump out to me are as follows:

1) If additional information is needed to determine whether additional deaths are related, why isn’t this information being gathered or at least requested from the providers or others who filled out the reports to make an adequate determination? For example, we have filed multiple adverse-event reports of clients, but to date WE HAVE NEVER BEEN CONTACTED BY THE FDA REGARDING THESE REPORTS, NEVER BEEN ADVISED OF THE STATUS OF THEIR INVESTIGATION, OR TOLD THAT ADDITIONAL INFORMATION IS NEEDED.

2) Is the FDA relying on death certificates to determine cause of death? If so, this analysis is suspect, as many individuals died before the public recall and before the medical community learned of the contaminated heparin. As such, a medical provider would not have known or appreciated that their patient could have died from an anaphylactic reaction from contaminated heparin.

3) Is the FDA investigating or supporting scientific studies to determine whether the contaminate, OSCS, and its resulting symptoms can cause or contribute to other complications leading to death, such as heart failure? To date, the FDA admits that it has limited knowledge “since the contaminant was only recently discovered.” (See FDA Questions and Answers, updated 7/3/08.) For example, the FDA admittedly does not know whether there are any long term health effects of the contaminant. (See FDA Questions and Answers, updated 7/3/08.) With the New England Journal of Medicine article (that had severely restricted testing parameters) being the only scientific study published to date regarding the effects of OSCS, it may be too quick to report that the only deaths caused by that contaminate are those from anaphylaxis or hypotension.

4) Why has the FDA failed to analyze any of the reports that were filed after March 31, 2008? Or if they have analyzed them, why have they failed to report on them?

5) Why did it take an interview with the Chicago Tribune to ferret out this important information?

Baxter, SPL and the FDA have each admittedly failed the American public with respect to Heparin. As such, it is in their best interests to minimize the national disaster that they allowed to occur. It is no wonder, therefore, that they are quick to try to limit the number of deaths. Speculation is worthless. What we need is science. We implore the scientific community to not accept the FDA’s and drug companies’ unfounded conjectures at face value, but to test and study this contaminate further. Only then will we reach the truth… something that the victims of this disaster and their loved ones deserve.

The FDA recently increased the number of reported deaths in which one or more allergic / hypotensive symptoms occurred in correlation to the receipt of heparin to 149 deaths.

*The reports in this table concern heparin produced by any manufacturer.

A review of this table shows a significant spike in events for the months of November 2007 through March of 2008. There is no doubt but that this spike is the result of deaths caused by the contaminant oversulfated chondroitin sulfate (OSCS), which was intentionally added to the raw heparin in China.

While there have been a few deaths related to products sold by other manufacturers, the overwhelming majority of the deaths arose from the administration of heparin manufactured and sold by Baxter.

There is also no question but that this table significantly underestimates the actual number of people who died from the contaminated heparin. The FDA adverse events reports only capture a relatively small percentage of the actual number of adverse events.

According to the FDA: "A small percentage of adverse reactions are reported to Centers for Deisease Control and Prevetnion and FDA by health care professionals and industry."

Therefore the actual number of deaths attibutable to the contaminated heparin is much larger.

According to Chinese news, the Chinese Ministry of Health announced Friday that despite its “joint investigation” with U.S. drug authorities, it could still not conclude that the multiple U.S. deaths were a result of contaminated heparin sold by Baxter, who bought the raw ingredient supplied by SPL from its facility in China, SPL Changzhou. (07/18/08 China View News: “Cause of deaths still in doubt after Sino-U.S. Investigation on Blood Thinner.”)

As you may recall, China’s drug agency reported the same inability to link the reported deaths in May of this year. (See our May 7, 2008 Blog: China Points the Finger at Baxter and the FDA.”) At that time, the inability of China and the U.S. FDA to cooperate was evident. Chinese officials claimed that Baxter and the FDA failed to provide them with medical records, medical histories, and information on Baxter's manufacturing practices. The Chinese also complained that they had not been given samples of the contaminated product. The FDA complained that it was not provided records from Changzhou Techpool Pharmaceutical Co. (“CZTP”), a company who supplied SPL Changzhou with raw heparin and may have been a source for the contaminant.

U.S. researchers confirmed the link between the adverse events, including death, and the contaminant, OSCS, since at least April 23, 2008, when the results of the first study were reported in an article published online by the New England Journal of Medicine entitled, “Contaminated Heparin Associated with Adverse Clinical Events and Activation of the Contact System.” As reported on the FDA website, “The contaminant activates chemicals in the body called enzymes. These enzymes cause the body to make inflammatory mediators (chemicals that are released by immune cells). Inflammatory mediators can lead to some of the symptoms such as low blood pressure, abdominal symptoms and shortness of breath.” (FDA: Questions and Answers re Heparin.)

It seems, therefore, that the two agencies are still failing to cooperate and exchange pertinent information. Maybe someone should give the Chinese Ministry of Health a copy of the New England Journal of Medicine article.

The FDA has updated its website FDA Questions and Answers on Heparin

The latest version contains new questions and answers about Heparin and its uses, further details on the FDA investigation, and describes the contaminant, oversulfated chondroitin sulfate (OSCS) and its effect on the human body.

For example, the new article adds the following question and answer:

18. Why does the contaminant cause serious adverse events? (new question and answer added 6/18/2008)

The contaminant activates chemicals in the body called enzymes. These enzymes cause the body to make inflammatory mediators (chemicals that are released by immune cells). Inflammatory mediators can lead to some of the symptoms such as low blood pressure, abdominal symptoms and shortness of breath. This mechanism can explain many of the serious adverse events that occurred immediately after patients were given the contaminated heparin.

Tomorrow I will write about the FDA inspections of the Chinese facilities.

The Saturday, May 31, 2008 edition of the Wisconsin State Journal ran a story on Scientific Protein Labs, the supplier of the contaminated heparin to Baxter. (SPL was formerly a division of Oscar Mayer, the hot dog company.) The story is worth reading for several reasons.

First, it describes the process involved in processing pig intestines into the raw sugar powder used to make heparin. This powder is called the api, or active pharmaceutical ingredient. Here in the United States, SPL controls its supply by actually processing the pig intestines. One 22 ton semi load of pig guts is processed down into just six pounds of heparin powder.

In China, SPL - Changzhou (SPL-CZL), an SPL joint venture, bought processed pig guts, rather than act as the parent company and purchase the raw pig guts. SPL-CZL purchased the material after some processing had been done. SPL - CZL then shipped the heparin powder in bags from China to Wisconsin. SPL did not even open the bags in Wisconsin, but simply forwarded them to Baxter's Cherry Hill, New Jersey plant. These bags contained material that had been "cut" with a counterfeit product that mimicked heparin. Up to 30% or more of the material was actually oversulfated chondroitin sulfate (OSCS).

What is new in this article is the admission that Baxter bought all of its raw heparin only from the China operation. The raw heparin that is made by SPL from domestic pigs is all sold to Sanofi Aventis, another drug company.

All of SPL's heparin was made in the United States until 2004, when it acquired the China operations. In China SPL purchases its raw materials from two different companies, and each of them obtain the processed raw material from 10 other workshops, which do the initial processing of the pig intestines. So the supply chain of SPL is much different than that here in the United States, a fact which should have been known by Baxter.

The most critical admission in the latest article is the admission by SPL that it feared suppliers would try to sell it counterfeit products because of the blue ear pig disease that was ravaging the pig supply in China. It started testing its incoming supplies to make sure that sheep intestines weren't being substituted. But amazingly it never utilized the common test of NMR until after it was too late.

It didn't even own an NMR machine.

CEO Strunce stated that he has learned a lesson. "The lesson is that you have to be constantly vigilant."

Mr. Strunce, that lesson was taught in drug manufacturing 101. You must have missed that class.

On Monday, during an interview with The Associated Press, U.S. Health and Human Services Secretary, Mike Leavitt, represented that the heparin in the United States is now safe in light of tighter testing and controls. (5/12/08 Chicago Tribune Article: “U.S. Health Secretary: Chinese Heparin Now Safe.”) He discussed the additional guidelines regarding quality and safety that exporters must now meet. I hope he is right. I hope that after months of Americans dying from contaminated heparin, import alerts at the borders and proper testing, heparin and all drugs coming into the United States are now safe. (Although based on the evidence presented to the U.S. House Commerce Committee on Energy and Commerce at the April 29, 2008 hearing entitled, “The Heparin Disaster: Chinese Counterfeits and American Failures,” I doubt this is the case.) But what about what is on our shelves already?
Unfortunately, just a week ago, the FDA stepped up its heparin alert to hundreds of hospitals, medical societies and pharmaceutical organizations after learning that some medical facilities still had contaminated heparin among their supplies. (5/9/08 Wall Street Journal, “FDA Issues Update Heparin Alerts to Medical Facilities.”) The notice to the facilities read, "Please help FDA spread the word about recalls of injectable heparin products and heparin flush solutions that may be contaminated with oversulfated chondroitin sulfate (OSCS). Affected heparin products have been found in medical care facilities in one state since the recall announcement…Although product recall instructions were widely distributed, they may not have been fully acted upon at all sites where heparin is used.”
Indeed, many manufacturers and distributors of medical products containing or coated with heparin have only recently begun to identify and recall products containing the contaminant, as requested by the FDA last month. For example, on Monday, Atrium Medical Corporation recalled selected lots of HYDRAGLIDE™ Brand Heparin-Coated Thoracic Drainage Catheters that were manufactured with heparin that was contaminated with OSCS. Likewise, on May 7, 2008, Medtronic, Inc. recalled selected products with a “Carmeda BioActive surface” that were manufactured with heparin found to have been contaminated with OSCS. The affected devices are disposable products used during cardiopulmonary bypass (CPB) for heart surgeries. Affected products include blood oxygenators, reservoirs, pumps, cannulae, and tubing packs.
This delayed response is unfortunately consistent with the experience of our clients, some of whom we believe received recalled heparin after the date of recall, or who never received notice of the recall from their pharmacy or medical facility. Authorities must continue to focus not only on what is being imported, but what is already within our borders. A blanket promise of safety to the unsuspecting American public should only be made when it is certain that it is a promise that can be kept.
