FDA Orders Amgen to Change Its Label for EPO

After beating Wall Street expectations and disclosing positive results from an osteoporosis (densomab) clinical trial, Amgen was ordered by the US Food and Drug Administration (FDA) yesterday to change the labels for its EPO drugs (Epogen and Aranesp) that will likely further restrict their use in treating patients with cancer.

The label changes ordered by FDA represent the first time that the agency has invoked its power to change prescribing information for drugs that it previously approved. In the past, FDA could only negotiate with drug manufacturers about changes to labels and prescribing information. In my opinion, it’s about time that FDA has been empowered to unilaterally order these types of changes. I have long contended that negotiations between the agency and drug makers about labeling and prescribing information is not in the best interests of Americans who use prescription drugs. To that end, it was negotiations between FDA and Merck about whether the serious cardiovascular risks associated Vioxx should appear on the Vioxx label (they didn’t) that lead to the misuse, safety problems and ultimate recall of the drug.

While the ordered label changes are not good news for Amgen and its partner Johnson and Johnson which sells Procrit (EPO manufactured by Amgen and sold by J&J), they are in the best interests of all Americans who use these drugs to treat anemia caused by cancer chemotherapy and kidney disease.

Until next time….

July 2008--Around the Web

This month Kevin has reviewed an eclectic bunch of websites. Continuing with his “down under” theme from last month, Kevin offers the Australian National Herbarium and the Darwin Correspondience Project websites (okay so Darwin was English but he did visit Australia!). The Darwin site complements an interesting site called the Origin of Life Prize (check it out).  

Another Australian website called the Sea Snake Homepage covers everything you ever wanted to know about sea snakes (and then some) but as Kevin put it may not be for everyone. There is a technical site called Microscope-Microscope.org which has some terse but valuable information on well—microscopes.

My personal favorite is the Biomedia Associates Educational Biology site. Although it is a commercial site, it is an education website and offers some valuable resources for biology teachers and students.

Until next time…

Merck, Gardasil and Sex and the City

As many of you may recall, Merck tried unsuccessfully last year to lobby state and federal officials to pass legislation that would require mandatory vaccination of girls aged 9-26 with Gardasil, its anti-HPV, cervical cancer vaccine. Merck came under fire for its efforts (which seemed ethically disingenuous to many). Consequently, the company’s image took a hit and its stock price started to tumble. Although Merck stopped its lobbying campaign (mostly because of bad press and a flagging stock price), Gardasil ads continued to run and went largely unnoticed.

Because GlaxoSmithKline may be close to launching CervarixTm—its cervical cancer vaccine—  the company recently decided that it was time to ramp up its Gardasil advertising efforts. Starting this past Saturday and continuing through June 26, Gardasil ads will be gracing the screens of a theater  near you. The ads will be shown with films like “Sex and the City” (hmmm, clever wouldn’t you say?), “Get Smart” (who doesn’t remember Barbara Feldon), “The Happening” (what woman doesn’t love a scary movie), “You Don’t Mess with the Zohan” (Adam Sandler is hot) and several others. I want to thank Ed Silverman over at Pharmalot for the heads up on this story!  I don't know about you, but I think that showing commercials at the movies, especially those hawking pharmaceutical products, is just plain wrong!!!!!!!!

This isn’t the first appearance of Gardasil ads at the cinema—I recall seeing an ad for Gardasil the last time I went to the movies (I don’t remember the movie but I clearly can recall the ad!). According to a Merck spokeswoman (aren’t pharmaceutical companies clever?), “We purchased advertised space that is relevant for our older female target audiences; specifically for the summer movies that are relevant to those aged 19 through 26.” 

As Ed so eloquently stated in his Pharmalot post: “Of course, plenty of teenagers will be seeing some of these flicks, too. Zohan and Get Smart are rated PG-13. And Sex and The Happening are rated R, but the restrictions only apply for kids under 17– some of whom will, no doubt, see them anyway.  In any event, Gardasil is unlikely to be available as a value pack that includes soda and popcorn. But we (Pharmalot) are curious to know whether the Gardasil beach towel is about to make a comeback.”

 Until next time….

The EPO Saga: The Demise of a Blockbuster Drug

Erythropoietin (EPO) is a hormone (protein) that regulates red blood cell production in humans. Back in the 1980s, scientists at a fledgling biotechnology company called Amgen determined that recombinant EPO was highly effective for treating anemia. Amgen owned the intellectual property rights to the EPO gene and decided to sell the recombinant protein encoded by EPO (called epoetin) as a treatment for anemia.EPO is known to alleviate fatigue caused by anemia by stimulating red blood cell production.

Amgen’s first EPO product, called Epogen, was approved in 1989 to treat patients suffering from anemia associated with renal failure. Procrit, Johnson and Johnson’s version of EPO (which was licensed from Amgen) was approved four years later in 1993 to treat chemotherapy-induced anemia. Aranesp, a longer acting version of EPO which is also manufactured by Amgen was approved in 2001 for anemia associated with chronic renal failure and in 2002 for chemotherapy-induced anemia in cancer patients.  All of the EPO drugs have gained blockbuster status and, over the past five years or so, the annual revenue generated by these drug is estimated to be $6.0 to $12 .0 billion.

Since their approvals, EPO, Aranesp and Procrit have been administered to tens of millions of kidney dialysis and cancer patients undergoing chemotherapy with minimal safety concerns and generally positive outcomes. However, with the looming specter of generic biologics (EPO lost patent protection in 2004) and competition from companies like Roche developing competing EPO products, Amgen stepped up its efforts to promote and sell EPO and Aranesp. This, in turn, caused EPO drugs to be used by many physicians, which ultimately resulted in additional safety warnings and a label change for all EPO products. The label change coupled with unrelenting negative publicity about Amgen’s promotion of its EPO franchise, caused its stock price to plummet and forced the company late last year to lay off 14% of its workforce.

Like other biotechnology and pharmaceutical companies, Amgen sought to find ne indications for its EPO products. To that end, there was some compelling evidence several years ago which suggested that EPOmight increase survival of cancer patients, when used with radiation and chemotherapy. The idea was that higher oxygen levels in the blood would make the radiation or chemotherapy being used to treat the patients' cancer more effective. With this in mind, several groups of investigators initiated human clinical trials to determine whether EPO treatment would benefit non-anemic cancer patients. Unfortunately, the New York Times reports that results from no fewer than eight clinical trials suggest that EPO drugs might actually promote rather than slow tumor growth and hasten the death of cancer patients.

Amgen believes that the increased trial deaths among EPO-treated patients resulted from blood clots rather than by promoting tumor progression or growth. The company contends that the amounts of EPO used in the trials exceeded what is recommended in the drug label and, at those levels, blood clots are a known common side effect. On the other hand, there is a growing body of evidence from a variety of sources which suggests that some types of human tumors express EPO receptors, which when stimulated by EPO binding, induces tumor cell proliferation. To make matters worse, when Procrit was first approved to treat chemotherapy-induced anemia, FDA regulators suggested in briefing documents that there may be a “hypothetical risk” that EPO could stimulate tumor cell growth. Nevertheless, neither FDA nor most EPO experts believe at this time that a direct link between EPO use and tumor growth has been established. Everyone agrees that more research must be conducted to verify or refute this idea.

Tomorrow, an advisory committee to FDA will consider placing further safety restrictions on the use of EPO drugs.  If they feel that blood clots were responsible for increased death among EPO-treated cancer patients then the recommendation would be relatively simple–only use the recommended modest levels of EPO to treat cancer patients as indicated on the product label.  However, if they believe that EPO directly stimulates tumor growth then even the currently recommended modest doses of the drug may be too risky to treat cancer patients. Regardless of the outcome of the tomorrow’s FDA advisory meeting, it is clear that Amgen’s flagship EPO franchise may be in serious jeopardy.

Until next time….

FDA Delays Another Decision on a New Antibiotic

Where have the folks at FDA been hiding for the past decade?  I thought that by now everybody had heard about multi-drug resistant bacteria and the need for new antibiotics. Why, I bet that even President Bush knows this –hmmmm– well, okay– but you get my point!

FDA announced today that it needs more data and time to evaluate Johnson and Johnson’s “new indication” NDA for its antibiotic Doribax (doripenem). The antibiotic is already approved to treat urinary tract and intra-abdominal infections. The company is seeking approval to expand treatment to cover nosocomial or ‘hospital-acquired’ pneumonia as well as ventilator-associated pneumonia.

The new application was submitted in June 2007 but the FDA’s request for new data means that the review period has been extended by at least three months. Doribax is licensed from Japanese drug maker Shionogi and is currently undergoing regulatory review in Europe, Canada and in other countries.

This delay comes less than a month after the agency cancelled a meeting of its anti-infective drugs advisory committee which was scheduled for February 28. At that meeting, the agency was scheduled to review another J&J antibiotic ceftobiprole, which is being co-developed with Switzerland’s Basilea Pharmaceutica. No reason was given by the agency for cancellation of the ceftobiprole
meeting which is being evaluated as a treatment of complicated skin and skin structure infections, including diabetic foot infections.

I am not sure why FDA can’t make up its mind about the approvability of new antibiotics. They certainly had little difficulty approving Vioxx, Zyprexa and Avandia.  Maybe FDA ought to hire some more microbiologists? 

Until next time….

Luck of the Irish-Ireland is a Great Place for Pharma and Biotech

Is it luck or good planning that has prompted many pharmaceutical and biotechnology companies to set up manufacturing and research operations in Ireland? In my opinion, the recent Irish pharma and biotech explosion has little to do with luck and everything to do with strategic vision, excellent planning and a well trained, inexpensive workforce.

Currently, 28 out of the 50 top pharmaceutical/biotechnology companies in the world have facilities in Ireland. Some of these companies are Merck, Wyeth, Genzyme, GlaxoSmithKline, Pfizer, Johnson and Johnson, Schering-Plough and Bristol-Myers Squibb. Seven out of 10 of the world’s top selling blockbuster drugs are now manufactured in Irish production facilities. 

Pharmaceutical companies were the first to set up shop in Ireland. However, biotechnology is growing rapidly and biomanufacturing is starting to over shadow traditional small molecule production. Companies including Wyeth, Centocor, Bristol-Myers Squibb, Organon Biosciences (now part of Schering Plough) and Allergan manufacture biologics and biotechnology products in Ireland. In fact, Ireland is home to the world’s largest biomanufacturing facility, Wyeth’s € 1.3 billion Grange Castle near Dublin.

So why pharma and biotech are companies flocking to Ireland? First, the Irish labor force is well trained, everyone speaks English (albeit with an Irish lilt) and wages are still low. Second, Ireland has the lowest corporate taxes in the entire European Union. Further, there are R&D tax credits and financial support for start ups.  For example, there is financial support to purchase consultancy and innovation vouchers worth €10,000, a substantial amount of money for any startup! Finally, and perhaps most importantly, the Irish government had the foresight to create a public/private enterprise known as the National Development Plan (2000-2006) that invested € 2.5 billion to create an Irish R&D infrastructure.

The Irish strategy–“built it and they will come”– has certainly paid off handsomely for Ireland. Another country that has embraced a similar strategy is Singapore–which through a public/private initiative has been building a vibrant life sciences and biotechnology industry since 1999. Both countries now compete for pharma and biotech business. For example, in late 2007, Merck decided to build a € 200 million vaccine facility at Carlow Town in Southeast Ireland. Novartis, on the other hand, opted for Singapore to build a new $180 million pharmaceutical tabletting facility along side of its API production plant.

Unlike Ireland, the American pharmaceutical and biopharmaceutical industries are in trouble and losing their competitive edge. Perhaps the US can learn a thing or two from the Irish to give its bioscience industry a much needed shot-in-the arm.

Until next year….
