FDA Pushed for Answers Regarding Bad Chinese Heparin

Like many Americans, including the families of hundreds of innocent victims killed from tainted Chinese heparin last year, Rep. Joe Barton, (R- Texas) is dissatisfied with the lack of information from the FDA regarding the heparin debacle.

Barton, (the ranking member on the House Energy and Commerce Committee), has asked the investigative arm of Congress, the Government Accountability Office, to investigate the FDA’s response to the heparin debacle. He has also sent a letter to Acting FDA Commissioner Joshua Sharfstein, demanding that the FDA turn over any databases relating to their investigation. (See 05/06/09 Article from NASDAQ, Jared A. Favole, “Rep. Barton Presses FDA for Information about Tainted Heparin.”)

An unidentified staffer for the Energy and Commerce Committee is quoted as saying, “We don’t seem to be any further along a year later from understanding [the heparin debacle]. What are they doing about it? Is this an acceptable practice in China?”

Last year, Barton also sent a letter to the former FDA Commissioner, Dr. Andrew von Eschenbach, seeking answers on why the agency took six months to confiscate 11 tainted batches of heparin from Celsus Laboratories (located in Cincinnati, Ohio) even though an inspection in April found that the company's recall was inadequate. (See Dec. 15, 2008 Blog, “Rep. Barton Questions FDA’s Six Month Delay in Seizure of Tainted Heparin.”) At the time, FDA officials said they could not give details because of "an ongoing investigation."

While we applaud these continuing efforts by Congress to get answers for the victims of the tragedy, similar inquiry should also be made of the responsible drug companies, including Baxter. It was Baxter who decided to purchase the cheaper, bad Chinese heparin from a Chinese plant that it knew had not been inspected by the FDA. Why? Corporate Greed. While the FDA certainly has a duty to provide information to the American public, we should not loose sight that it is ultimately the drug companies, including Baxter, who are responsible for ensuring the safety of their supply chains.

Barton wants the FDA to respond to his letter within two weeks. We will continue to keep you updated as to any response from the FDA.

Grassley, Kennedy Introduce Bill to Protect Against Contaminated Imported Drugs

Sens. Chuck Grassley (R-Iowa) and Edward Kennedy (D-Mass.) introduced new legislation in Congress last week that would broaden the FDA’s inspection and enforcement authority with respect to foreign drugs and medical devices. To view the press release on the proposed legislation, click here.

This legislation, referred to as “The Drug and Device Accountability Act of 2009,” would give the FDA money to conduct foreign drug plant inspections. As stated by Sen. Grassley, “An increasing number of drugs and ingredients for pharmaceuticals are being manufactured in other countries, yet studies show the FDA doesn’t know how many foreign plants are subject to inspection, and the FDA conducts relatively few foreign inspections each year. Our legislation is a practical solution to beefing up the FDA’s inspection work, both domestically and abroad, and holding the FDA accountable for its review of medical devices, where questions have been raised about the agency’s work.”

The proposed legislation would also give the FDA the power to detain products from foreign plants when inspectors believe that a drug, (such as the dirty Chinese heparin that recently killed hundreds of Americans), has been adulterated. This is important because the FDA currently has no alternative, but to rely on the overworked and unfunded U.S. Customs to handle the actual seizure of suspect imported goods.

The bill would also give the FDA the power to issue subpoenas allowing the agency to obtain internal business records from careless drug manufacturers who ship production of their drugs overseas in order to increase corporate profit and avoid regulation meant to protect the American public. As discussed previously in our May 21, 2008 blog, “FDA Needs Subpoena Power,” without this ability, the agency is powerless to obtain internal business records from a negligent company who has allowed contaminated drugs to be sold, (such as Baxter who sold the dirty Chinese heparin from a foreign plant that Baxter knew had never been inspected by the FDA or any other governmental agency).

The FDA is one of the few Federal agencies that currently lacks subpoena power. As previously noted by Rep. Bart Stupak, (Chairman of the investigations panel of the House Commerce Committee), in a letter last year to the former FDA Chief, “An integral part of ensuring the FDA can protect the American people is equipping the Agency with proper resources and enforcement authority it currently lacks….In some cases, the FDA does no testing of its own, and in making decisions it must rely entirely on the test results submitted by manufacturers. Without subpoena power, the only way the FDA can ensure it has the information it needs it to threaten criminal prosecution by the Justice Department if it finds critical data is withheld.”

Finally, the proposed legislation would also require certification of applications for drugs and devices needing FDA approval and establish civil and criminal penalties for false or misleading certifications.

To fund the new powers, the bill would levy fees on plant inspections, thus putting the cost on the drug manufacturers who decide to send production overseas.

This regulation would likely have prevented the Heparin debacle and saved the lives of hundreds of innocent Americans. As such, we commend and support this important legislation.

Washington Post Reports on Needed FDA Overhaul

The Washington Post reported today that former officials, members of Congress, watchdog groups and various government reports are calling for an overhaul of the FDA, which “desperately needs an infusion of strong leadership, money, technology and personnel -- and perhaps a major restructuring.” (11/26/08 Washington Post, “Ailing FDA May Need a Major Overhaul, Officials and Groups Say.”)

The article is worth the read and discusses some of the FDA’s recent failures to monitor imported drugs and consumer products, including contaminated heparin, toothpaste, and pet food from China. As similarly opined in this blog recently, the article also discusses the view that more needs to be done than simply starting to open offices overseas, including sharply boosting inspections abroad, developing strict new regulatory standards, and updating and integrating the FDA's computer systems.

Questions Raised Over FDA's Investigation of Heparin Deaths

In a letter to the Government Accountability Office (GAO) dated November 19, 2008, Rep. Joe Barton questioned the adequacy of the FDA's ongoing investigation and evaluation of the recent heparin deaths, casting doubt on whether the FDA in fact has used all available postmarket surveillance tools when determining the likelihood that contaminated heparin caused patient fatalities. Specifically the letter states, “Based on the available information …there is a serious and potentially troubling question about whether FDA availed itself [of] all of its tools to conduct comprehensive surveillance of heparin deaths.” The letter also questions "whether [the] FDA has confounding or conflicting information about Heparin death cases that has not been made public." A copy of this letter is available by clicking here.
As first described in our July 30, 2008 blog, we also have questions concerning the conclusions reached by the FDA as reported to the Chicago Tribune and Nightline. For example, is the FDA investigating or supporting scientific studies to determine whether the contaminate, OSCS, and its resulting symptoms can cause, contribute to, or leave an individual susceptible 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” and that all effects are not yet known. (See FDA Questions and Answers, updated 7/3/08.)) Without such studies, the FDA's conclusions may be premature.
Likewise, if the FDA requires additional information 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, as we stated in our July blog, while we have filed multiple adverse-event reports of clients, 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.
We have been contacted, however, by many caring lawmakers, journalists, and scientists who have not forgotten the victims of the heparin disaster. We commend and support their ongoing efforts to obtain answers and accountability from the FDA, Baxter and SPL.

Spiked Baby Formula: Yet Another Warning To U.S. Companies

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.

*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.

Chinese Authorities Still Doubt Deaths are a Result of Contaminated Heparin

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.

Congress Demands Documentation Supporting the FDA’s Change in Position Regarding Preemption of Product Liability Lawsuits

On June 26, 2008, Congressman and Chairman of the House of Representatives’ Committee on Oversight and Government Reform, Henry A. Waxman, sent a letter to the FDA Commissioner demanding production of documents that explain why under the Bush Administration, the FDA changed its position regarding whether FDA regulation should bar liability claims. (To view this letter, click here.)

Prior to the Bush Administration, the FDA had a long-standing position that despite its regulation of medical drugs and devices, “product liability lawsuits in state court complement the agency’s regulation of drugs and medical devices, providing an important additional layer of consumer protection against unsafe products.” (See 06/26/08 Letter to Eschenbach.) As such, the FDA did not interfere or challenge the constitutional right of innocent Americans injured by defective products to hold the drug companies responsible in a court of law.

On May 14, 2008, the House of Representatives Committee on Oversight and Government Reform, held a hearing on the issue of preemption of state liability claims related to FDA-approved drugs and medical devices. (We have previously blogged on this hearing and the problem with preemption. See prior blogs, “Should FDA Drug and Medical Device Regulation Bar State Liability Claims?” (05/14/08); “FDA Needs Subpoena Power” (05/21/08); “The Preemption Problem” (06/04/08); “Draft Bill Regarding Preemption To Be Introduced” (06/13/08)).

Despite the FDA’s long-standing position regarding preemption, the current FDA Deputy Commissioner for Policy, Randall Lutter, testified at the hearing that under the Bush Administration the FDA reversed its position and calls such suits a “challenge” to the agency that have “detrimental effects on the public health.” (For a transcript of this hearing, click here. For a video, click here.) As such, under the Bush Administration, the FDA now sides with drug manufacturers. They argue that regardless of any misconduct or failures on behalf of the drug companies, Americans injured by defective drugs should be stripped of their constitutional right to a trial by jury for most, if not all, legal claims, where the drugs are regulated or approved by the FDA, giving negligent drug companies almost complete immunity.

Ironically, this position comes amidst the heparin disaster, wherein the FDA has admitted that it does not have the resources, authority and capability to ensure product safety. (See 04/29/08 Video of House of Representatives’ Subcommittee on Oversight and Investigations Hearing, “The Heparin Disaster: Chinese Counterfeits and American Failures; 04/22/08 Video of House of Representatives’ Subcommittee on Oversight and Investigations Hearing, “FDA’s Foreign Drug Inspection Program: Weaknesses Place Americans at Risk.”) Indeed, the FDA currently does not even have subpoena power, which would allow the FDA to demand certain documents from companies who have sold contaminated drugs. Without this ability, the agency is powerless to obtain internal company documents that a company itself chooses to withhold. (See prior blog, “FDA Needs Subpoena Power” (05/21/08)).

The June 26, 2008 letter asks that the requested information/documents be produced by July 11, 2008.

The FDA China Inspections

The US FDA inspected, or rather attempted to inspect, three heparin manufacturing facilities between February 20th and February 29, 2008. The first facility was that of Changzhous SPL Company, Ltd., ("CZ-SPL") a wholly owned subsidiary of SPL. All of the CZ-SPL product was shipped to Baxter.

This inspection lasted 6 days. This was the first time the FDA had ever inspected the facility, in violation of FDA policy.

The inspection found that the process validation for the purification of Heparin Crude was inadequate . It further found a number of other deficiences, including:
  • process changes included removal of Heparin Crude quality attributes based on ease of procurement without adequate raw material evaluation.
  • No impurity profile had been established.
  • A discontinued workshop's crude heparin was included in lots sold to SPL.
  • Equipment was not cleaned.
The report states that, beginning in June of 2007, CZ-SPL started testing incoming lots by Polymerase Chain Reaction (PCR) for species verification. In other words, because SPL was worried about counterfeit sheep product being substituted for pig product, it started doing a basic PCR analysis. As a result of the inspection, the FDA issued a Form 483 report.

The second inspection began February 27, 2008. This inspection was of a facility located right next door to CZ-SPL. The neighboring factory is known as Changzhou Techpool Pharmaceutical Co. Ltd. ("CT"). CT is 45% owned by CZ-SPL. All of the product made by CT is sold to CZ - SPL. Importantly, the plant is not registered with the Chinese FDA because it does not make product for consumption in China. Nor is it registered with or inspected by the US FDA. The inspection lasted only 2 days. On both days the company refused to give the FDA copies of basic documents, including raw material crude specification, test methods, cards, certificates of analysis, blend records, and inventory records. The FDA did take photographs, which we are seeking to obtain.

The third inspection was even less successful. This inspection began the afternoon of February 28th and ended the next day when the FDA inspection team was refused reentry into the facility. This facility was located in Hangzhou, China. The name of the firm was Hangzhou Ruihua Biochemical Products Co. Ltd. This firm was a manufacturer and tester of crude heparin that was sold to CZ-SPL for further processing. A photograph of Dr. Wang, the general manager of CZ-SPL and an officer of SPL hung in the entryway of the facility.

The firm refused to provide copies of any records and no samples were collected. The firm is not regulated or inspected by the Chinese FDA or the US FDA. The owner of the firm, Mr. Ruihua, admitted that the firm had been unable to meet the needs of CZ-SPL because there was not enough heparin available. He indicated that CZ-SPL was his sole customer.

Ruiha collects raw heparin from the countryside and nearby provinces. The workshops are all on a list provided by CZ-SPL. However Mr. Ruiha refused to provide any documents, refused to permit the FDA to inspect the laboratory, refused to provide a list of the workshops from which they get the raw heparin, and would not even state the Provinces in which the workshops were located.

On April 21, 2008 the FDA issued a warning letter, which held that the deficiencies and deviations from current good manufacturing processes were so severe that CZ-SPL was barred from shipping product into the United States.

FDA revises information on Heparin

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.

Heparin Death Reports Nearly Double

The FDA issued an updated report yeseterday on the number of deaths reported after heparin administration that occurred and were submitted to the FDA from January 1, 2007 through May 31, 2008. (See FDA 06/17/08 “Information on Adverse Event Reports and Heparin.”)

According to the FDA, as of May 31, 2008, there have been 246 reports of death in patients receiving heparin since January 1, 2007. Out of the 246 reported deaths, 149 of the reports included one or more allergic symptoms or symptoms of hypotension. This report is nearly double the FDA's earlier report in April 2008, which advised of 131 reported deaths, with 81 of those reports including one or more allergic symptoms or symptoms of hypotension.

The FDA's Center for Devices and Radiological Health (CDRH) has also recently reported 11 deaths and 86 injuries since January 1, 2008, which have been linked to use of medical devices containing heparin. (06/03/08 FDA web update: "Questions and Answers on Heparin, Medical Devices and In-vitro Diagnostic Assays.") The heparin in the majority of these medical devices was found to be contaminated with OSCS.

Promises of Safety

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.
