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….

FDA Advisory Panel Gives a "Thumbs Up" To Continue Using EPO for Cancer Patients

According to Johnson & Johnson, a panel of advisors for the Food and Drug Administration, in a surprise decision, supported keeping Epogen, Procrit and Aranesp from Amgen and Johnson & Johnson on the market for use in cancer patients who are anemic from chemotherapy.

The advisor panel voted 13-1 to keep Amgen's Aranesp and J&J's on the market for use with chemotherapy. The recommendation was very surprising because over the last year FDA has scrutinized the drugs because of safety concerns and recently added new warnings to the labels. Many analysts expected further recommendations for restrictions. Although the advisory panel vote is non-binding, FDA usually follows the advice of its panels when making regulatory decisions. However, it is important to note that FDA has not followed the advice of several advisory panels in the recent past.

The positive advisory panel vote is good news for J& J and Amgen because billions of dollars in revenue are at risk for the cancer indication.  I bet that J & J and Amgen executives breathed a collective sigh of relief after hearing the news!  Maybe that loud noise I heard earlier today was the popping of champagne corks at J & J corporate headquarters in New Brunswick, NJ.  

To quote Mark Twain: “The rumors of my death have been greatly exaggerated” is particularly apt for Amgen and J &J after today’s decision.

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 Adds Black Box Safety Warning to EPO Drugs

Amgen announced today that US regulators added black box warnings to its erythropoietin drugs, Epogen and Aranesp. Similar warnings were also added to Johnson and Johnson’s Procrit which is licensed from Amgen. For those of you who don’t know, getting a black box warning on a drug label is like getting the “kiss of death” from a marketing and sales perspective. It certainly will not help sales of these products!

The new warnings approved by the Food and Drug Administration warn that the company's drugs increased death and accelerated tumor growth in patients with several types of cancer, including breast and cervical. Prior labeling warned of similar risks in other types of cancers.

The actions taken by the agency were not unexpected but suffice it to say there are a lot of unhappy Amgen and Johnson & Johnson employees in a Thousand Oaks, CA and New Brunswick, NJ

Until next time….

Amgen Executives Must Stand Trial in Stock Manipulation Case

A federal judge ruled that Amgen Inc. must defend itself against charges that it misled investors about safety concerns with its flagship anemia drug, Aranesp.

A US district court judge dismissed charges against five of nine Amgen officers and directors but left plaintiffs 30 days to amend their complaint in order to include those defendants. The investors, led by Connecticut Retirement Plans and Trust Funds, assert that positive statements made by company officials regarding the safety of Amgen's two anemia drugs, Aranesp and Epogen, were knowingly at odds with clinical studies that had raised concerns.

The plaintiffs assert, according to court filings, that they unknowingly purchased artificially inflated shares, between April 2004 and May 2007. In one instance, during its fourth-quarter 2006 conference call, Amgen announced results of a clinical trial that tested Aranesp in 939 patients with anemia from cancer. The Food and Drug Administration, according to court filings, described the study as "demonstrat(ing) significantly shorter survival rate in cancer patients receiving (anemia drugs) as compared with those (sic) receiving transfusion support."

Describing the results of the study during the conference call, Roger Perlmutter, a defendant and executive vice president of research and development, said, "We did not see a statistically significant adverse affect of Aranesp on overall mortality in this patient population, and so we conclude that the risk/benefit ratio for Aranesp in these extremely ill patients with anemia secondary to malignancy is, at best, neutral and perhaps negative."

Sounds misleading to me! It is unfortunate that companies compromise their scientific integrity and corporate reputation simply to boost their stock price in the short term. I think companies are slowly learning that if they are dishonest or disingenuous with the American public that the public will soon lose confidence in them and their products. This, in turn, will lead to a decrease in sales and ironically a reduction in company stock price. As the old adage goes “Honesty is always the best policy!”

Until next time….

Amgen Takes Another Beating

Can anything else go wrong at Amgen? FDA regulators said on Thursday that they were reviewing the results from two recent studies that provided more evidence of serious risks for some cancer patients treated with anemia drugs, sold by Amgen Inc (Epogen & Aranesp) and Johnson & Johnson (Procrit). For those you who don’t know, J&J licensed Procrit from Amgen so there is really little difference between J&J’s Procrit and Amgen’s Epogen. Aranesp is a second generation, longer-acting version of Amgen’s Epogen.

In the studies, researchers used  Aranesp or Procrit to elevate a patient's level of hemoglobin to 12 grams per deciliter or higher, although many patients did not reach that level. Current warnings on the drugs say hemoglobin levels should not rise above 12 for patients with cancer. The FDA said the studies showed that patients with breast or advanced cervical cancer who were treated with the drugs died sooner, or had more rapid tumor growth, than similar patients who were not given the medications.

Based on these new data, it is almost certain that the agency will insist on label changes to include strong warnings regarding the use of EPO drugs to treat oncology patients. Maybe there is a black box warning in Amgen’s future?

Amgen's stock hit a new 52-week low on Thursday, dipping down to $45.25 and closing at $45.69. It has traded as high as $76.95 in the last year but has taken a beating with the decline of its anemia-drug franchise.

The similarities between Amgen and Pfizer are becoming more apparent each day. Both are largest companies in their respective sectors (biotech and pharma) and have relied almost exclusively on blockbuster franchises (and weak pipelines) to bolster their stock prices! As you may recall, both companies have laid off large numbers of employees over the past year to cut costs. Maybe bigger (biggest) is not always better?

Until next time….
