She already has Senator Edward M. Kennedy’s support. “Her expertise is valuable for problems we now face, such as combating food-borne illness, cooperating with other agencies to address the new flu outbreak and drug-resistant diseases, and protecting our food and drug supplies,” Sen. Kennedy said in a statement for the Health, Education, Labor, and Pensions Committee hearing.

If confirmed, one of Dr. Hamburg’s many priorities will be to detangle the mess left behind from last year’s contaminated heparin scandal, in which batches of tainted heparin manufactured in China made their way into the United States. Those bad batches killed more than 80 people and sickened hundreds more. An investigation resulted in the FDA’s admission that it did not have the resources or the funding to adequately inspect foreign food and drug manufacturing companies.

The agency’s handling of the heparin scandal is currently under review by the Government Accountability Office, and congressional leaders are not letting up on their insistence that the FDA make better provisions to ensure the food and drugs imported into the US are safe.

“It is abundantly clear that the agency needs strong, new leadership to improve morale and make it once again the world class agency that Americans can trust to protect the health of their families,” Sen. Kennedy wrote. “I’m very pleased, therefore, that President Obama has nominated Dr. Margaret Hamburg to lead the FDA as its new Commissioner.”

Sharfstein made headlines in 2007 when he convinced the FDA to restrict the use of over-the-counter children’s cough and cold medicines based on evidence they can cause serious health complications and even death in children.

If there is one government agency that needs overhauling, it is clearly the FDA. The agency has been under scrutiny for the past few years over contaminated food and drug products that have harmed and even killed Americans.

The agency is still feeling the repercussions from the tainted heparin scandal. Last year more than 80 Americans died and several more were made seriously ill after receiving injections of specific batches of the blood thinner that had been manufactured in a China plant. Those batches were found to have been contaminated with oversulfated chondroitin sulfate (OSCS), a contaminant that mimics heparin but can cause serious allergic reactions.

Following the revelation, the FDA admitted that it simply did not have manpower to properly inspect foreign food and drug manufacturing plants. Since then the FDA has taken measures to step up its inspections by opening field offices overseas. The first three offices opened late last year in China.

The FDA employs more than 11,000 employees and an annual operating budget of $2 billion.

Such is the case with the blood thinner heparin, which last year was the focus of much scrutiny when 80 Americans died and hundreds more were sickened after receiving doses of heparin manufactured in China. An investigation found that batches of heparin manufactured in Baxter International’s China plant had been contaminated with oversulfated chondroitin sulfate (OSCS). OSCS mimics the appearance of heparin but cause adverse reactions and even death.

Years ago most drugs were manufactured in the U.S., but over the years those operations have moved overseas – in particular, to Asia – where labor, construction, regulatory and environmental costs are lower. The FDA also inspects domestic plants far more often than foreign ones, which also adds to pharmaceutical companies’ production costs.

Following the heparin contamination last year, the FDA admitted that it was not sufficiently staffed to inspect all foreign offices. Thus, the agency has since begun to set up offices in foreign countries. To date, offices have been placed in China and India. The FDA also launched a voluntary two-year “Secure Supply Chain” pilot project to help promote the safety of drugs and active drug ingredients made outside the U.S.

Heparin is a blood thinner that is routinely used before certain types of surgery or other procedures to prevent clotting. It also is widely used for patients with chronic thrombotic conditions. Heparin is administered intravenously, which requires constant monitoring of doses and in-patient hospital stays. An oral alternative could reduce the need for expensive hospital stays.

About 2 million Americans each year suffer from thrombotic conditions and another 200,000 die each year from stroke, myocardial infarctions or pulmonary emboli as a result of thrombosis, according to the report.

The heparin will use glycosaminoglycan (GAG) technology to develop the oral alternative.

“The introduction of an oral heparin into clinical medicine would be a significant development and would have commercial, therapeutic and economic potential. We are pleased that Glycotek will take on this important challenge while at HCAR,” said Laura Butcher, Executive Director of HCAR, in the Business Wire report.

Glycotek will pursue both business and research and development activities at HCAR. Building upon its activities already in practice at its New York location. HCAR provides state-of-the-art facilities and high-value business and research resources.

Lovenox, the company’s number one selling medicine, was first recalled last June after some batches of its pre-filled injectible solution were found to be contaminated with trace amounts of oversulphated chondroitin sulphate, according to Reuters.

Oversulphated chondroitin sulphate is the same contaminate found last March by the Food and Drug Administration (FDA) in batches of heparin that killed more than 80 Americans and sickened hundreds more. Those batches were traced back to Baxter International’s Chinese plant.

The level of contaminant found in Lovenox was much lower than what was found in the heparin manufactured by Baxter International, according to Forbes.

So, what exactly is oversulphated chondroitin sulphate?

According to a March 20, 2008, New York Times report, chondroitin sulphate is an inexpensive and readily available dietary supplement made from animal cartilage. In its natural state chondroitin sulphate does not have anticlotting properties, however when it is altered to what is called oversulphated chondroitin sulphate, it mimics heparin.

According to the FDA, oversulphated chondroitin sulphate is not an approved drug in the U.S., nor should it be found in heparin, as it likely caused the allergic reactions that have killed and sickened so many individuals worldwide.

The NanoBioTech 2008 conference was held Monday at the Institute, and addressed topics including the developments in nanotechnology law, protecting intellectual property, and attracting investors, according to an article in the Times Union.

Linhardt presented information about research that combines heparin, an anticoagulant, with cellulose to create a membrane that can be used in kidney dialysis, the report says. The work also moves scientists closer to creating a “paper battery,” which is that same membrane strengthened with carbon nanotubes that act as electrodes.

According to the Times Union story, Linhardt told the conference audience that the battery can be powered by the body’s own fluids, like blood, sweat or tears, which act as electrolytes. The battery is an energy storage device that can be implanted in the body to provide power to operate medical devices like pacemakers, defibrillators and pumps, the scientist says.

According to a report in the Pharmaceutical Business Review, APP currently manufactures nine products at its Puerto Rico facility, including doxycycline, azithromycin and diphenhydramine. The report says the company plans to manufacture more than 19 million units in Puerto Rico during 2008 and to eventually transfer more than 25 additional product codes to the facility.

The recall of contaminated heparin manufactured in China has affected the availability of the product, which is a blood thinner used in surgical procedures.

Baxter International, Inc., recalled all remaining lots and doses of its sodium injection multi-dose, single-dose vials and HEP-LOCK heparin flush products, both preserved and preservative-free, in February, and suspended production of the products. Prior to the recall, Baxter manufactured about half the multidose vials used each month by health care providers.

APP expects the transfer of its additional product codes to the Puerto Rico facility will translate to approximately 50 million units annually. APP currently has manufacturing facilities in Illinois and New York.

Pharmaceutical Business Review quotes Tom Silberg, CEO of APP Pharmaceuticals, as saying, “Bringing this third manufacturing site on-line is an important part of our commitment to ensuring that an uninterrupted and safe supply of heparin of the highest quality is available for US patients.”

Founded in 1996, APP Pharmaceuticals is a leading manufacturer of multi-source and branded injectable pharmaceutical products for acute medical care both in patient and ambulatory settings.

Linhardt was among the researchers who discovered the source of tainted heparin that was responsible for at least 149 deaths since the beginning of 2007. Manufacturer Baxter International, which supplies about half of the heparin used in the U.S., recalled its supplies of heparin made in China after more than 80 patients suffered serious allergic reactions and death following its use.

According to a report by Bloomberg News Service, Chinese pig farms that provide source material for heparin are not monitored by the U.S. Food & Drug Administration, which increases the risk for contamination. Continued use of traditional heparin products manufactured in these facilities leaves the door open for another contamination event, Linhardt says in the Bloomberg report.

In addition to Baxter’s product, a smaller scale contamination problem was reported with the Lovenox heparin medicine manufactured by Sanofi-Aventis, according to a report by Reuters.

Linhardt presented his team’s synthetic heparin results at the recent American Chemical Society meeting, according to Reuters, where he told those in attendance that today’s heparin manufacturing methods are “simply unsafe.”

Scientists are working on creating larger quantities of the synthetic heparin, which Linhardt hopes will reach human clinical trials in five years, Reuters reports.
