Amgen and J&J: Falling in Love All Over Again

With most of our bloggers on vacation, we haven't yet troubled ourselves to analyze the Bristol bid for ImClone (if imitation is the sincerest form of flattery, we trust Roche is feeling good). And we didn't jump on Sanofi's buyout of Acambis either. (Thank goodness our colleagues at "The Pink Sheet" DAILY actually work in August!)

But even the dog days of summer can't stop us from taking note of this one: Amgen is giving global rights (except for Japan) to a clinical stage neuropathic pain project to...(drum roll please) Johnson & Johnson.

Considering the companies have spent the past two decades in an endless series of disputes, arbitration and litigation over their last licensing deal, involving a little product called EPO, that is news indeed.

If there ever was a case of adversity bringing people closer together, this is it.

Amgen and J&J have both said that their working relationship has been improved by the all-out effort to save the EPO franchise from regulatory and reimbursement challenges. So much so that Amgen CEO Kevin Sharer told the JP Morgan conference in January that “I never thought I would say this, but this circumstance has made us and J&J quite effective partners.” That may not be much of a silver lining from everything that has befallen EPO--but it sure is hard to imagine the two companies reaching this agreement two years ago, when the only place their executives were likely to exchange confidential information was in court.

Amgen's willingness to deal with J&J also suggests that it really means business when it talks about winnowing down its pipeline. In fact, Amgen has already shown it means business, in fact; Japanese rights to the neuropathic pain compound were already sold as part of a large partnership with Takeda in Japan.

Now the terms. Amgen receives $50 million up front--or a refund of one-quarter of the $200 million Amgen paid to settle antitrust litigation with J&J over EPO last month. Amgen will also receive development milestones of up to $385 million. There are additional commercial milestones and a sales royalty too.

And, no, there is no copromotion agreement.

Biopharmaceuticals: A New Paradigm In Clinical Pharmacology

Beginning in the late 1970s, biopharmaceuticals were being researched for conceptual production in those places once called academic institutions, and conducted basic research to identify new product candidates and applied a great amount of research. The same protocol is applied with biopharmaceutical companies today as it was then.
The first biopharmaceutical ever was synthetic insulin called Humulin made by Genetech in 1982, that utilizing what is called rDNA technology, which also is used to produce human growth hormones. Later the rights were sold to Eli Lilly for this insulin. Yet Genetech was the catalyst for biopharmaceutical growth. And they are truly research-driven. Today, they employ near 1000 scientists to continue their drive to research.
Biopharmaceuticals are distant and covert relatives of big pharmaceuticals, whose products are typically small molecule and carbon based in their design. Due to the lack of innovation and creation of truly unique products, large pharmaceutical corporations in particular have become intimate with the innovative biopharmaceutical companies more often now than ever. In fact, large pharmaceutical companies often acquire biopharmaceutical companies. These large pharmaceuticals do this because of the unlikely possibility that biopharmaceuticals will have generic products with therapeutic equivalents for some time. In addition, biopharmaceutical companies have historically been and experienced accelerated growth that has proven to be quite lucrative for them.
How do these drugs differ from typical drugs that have been made before this advent of biopharmaceuticals? Unlike the small molecule, synthetic, carbon based pharmaceuticals of yesterday, biopharmaceuticals, classified under what is called Red biotechnology due to this being a medical process in the biotechnology world, essentially are larger and very complex modified proteins derived from living biological materials that vary depending on what medication will be manufactured and for what disease state. In fact, it is difficult to identify the clinically active component of a biopharmaceutical drug, which is why there is no pathway for generic copies of such drugs, as it would require expensive and meticulous clinical trial processes. Yet recently, a company called Insmed demonstrated bioequivalence to Amgen’s Nupogen that increases white blood cells. While there still is no defined pathway for follow-on biologics, this study demonstrated that another biologic drug can show that it is therapeutically equivalent, known as a biosimilar drug. Insmed’s drug in this study will not be available for marketing until next year or later, though. Amgen recently had to pay a settlement to JNJ, who makes an identical drug called Procrit, for rebates and incentives Amgen was giving Oncologists for using Nupogen, and this will be addressed later.
Also, a transformed host cell is developed to synthesize this protein that is altered and then inserted into a selected cell line. The master cell banks, like fingerprints, are each unique and cannot be accurately duplicated, which is why there are no generic biopharmaceuticals as of yet, as there is no known process to create them. So the altered molecules are then cultured to produce the desired protein for the eventual biopharmaceutical product. These proteins are very complex and are manufactured from living organisms and material chosen for whatever biopharmaceutical that may be desired to be created. It is difficult to identify the clinically active component of biopharmaceutical drugs. So manufacturing biopharmaceuticals clearly is a different and innovative process, and a small manufacturing change could and has raised safety issues of a particular biopharmaceutical in the developing process. Also, it takes about 5 years to manufacture a biopharmaceutical. And each class has a different method of production and alteration of life forms to create what the company intends to develop. Yet overall, their development methods are rather effective.
Over 20 biopharmaceutical drugs were approved in 2005, I believe, and their growth tripled of what large pharmaceuticals experienced then. Also, just last year, biopharmaceutical companies made close to 80 billion in sales as well. Presently, over 20 biopharmaceutical products are blockbusters by definition. They are overall very effective treatments for what are viewed as very difficult diseases to manage. This is due to the fact that some pharmaceutical products target specific etiologies of these diseases, while limiting side effects because of the specific way in which such products work.
Unlike traditional medications that have been created in the same way for decades, biopharmaceutical companies seek through their research specific disease targets by genetic analysis and then search for a way to manipulate this target in a very specific way to provide superior treatment for such patients. Furthermore, these products are biologically synthesized and manipulated to maximize their efficacy while not crossing into a patient’s bloodstream.
There are about a dozen f different classes or mechanisms of action of biopharmaceuticals that have about a half of dozen different types of uses today. Label alterations for additional disease states occur often as well due to the progressive and novel effectiveness of biopharmaceuticals. Some of these drugs are catalysts for apoptosis of tumor cells. Others may cause angiogenesis to occur to block blood supply to the tumors of cancer patients. Then some biopharmaceuticals have multiple modes of action that benefit certain patient types and their diseases greatly, as with most biopharmaceutical products, the safety and efficacy is evident and reinforced with clinical data and eventual experience with the biopharmaceutical that is chosen to be utilized. And this clinical data is of a different method as well in comparison with what are traditional medications. For example, patients in the clinical trial involving a pharmaceutical are profiled, which allows better interpretation of this clinical data on their products.
Some biopharmaceuticals appear to be more noteworthy than others, such as Enbrel, which was originally created for the many forms of RA, which is a devastating form of arthritis that is caused by the patient’s own immune system attacking them to manifest this disease. Genetech has medications of similar benefit for different disease states as well.
A newer entry into the biopharmaceutical industry is Talecris Biotherapeutics, which is involved with such therapeutic areas as Immunology, Pulmonology, and Hematology. This company was formed in 2004 after the acquisition of Bayer’s plasma business, and they are doing quite well, as they have exceeded a billion dollars in revenue with their products.

Partnering of biopharmaceutical companies and larger pharmaceutical companies began during this time as well, if not being acquired by large pharmaceutical companies. Needless to say, large corporate pharmaceutical companies have a very high affinity for potential blockbusters.
The country of Belgium provides the most biotech products to the biopharmaceutical companies in the United States, and the U.S. leads the world in regards to biopharmaceutical product creation- with more than 70 percent of both revenues and research and development expenditures in this country. Canada is ranked number two in this area, others have said.
Some biopharmaceutical drugs are more profitable than others as well. Biopharmaceuticals compose around 10 percent of the pharmaceutical market presently, I understand. And with the government health care programs who are the largest U.S. payers for pharmaceuticals, Medicare pays 80 percent of the cost of biopharmaceuticals, as many are administered in the doctor’s office.
One other controversial, yet profitable biopharmaceutical class is known as EPOs. The two that are available are actually identical, yet have different names of Procrit and Epogen. Both are indicated for anemia that is experienced in patients on dialysis or who have cancer in particular. Doctors are monetarily incentivized to exceed dosing requirements of these agents for their anemic patients. When this happens, it potentially causes premature deaths as well as accelerating the progression of cancer patients placed on one of these meds. Once this tactic was exposed, there are now limitations regarding the amounts authorized to be given to particular patients placed on these EPOs. They are in the class of hormone biopharmaceutical drugs, which is another type of several classes of biopharmaceuticals, and they reduce the need for blood transfusions as they increase RBC proliferation safely and effectively if dosed properly.
Another controversy involving biopharmaceuticals is that, while they overall are very efficacious and safe, the typical cost of biopharmaceuticals is rather unbelievable, as the cost approaches 10 thousand dollars a year for many of them. Furthermore, with cancer drugs, they are used together with chemotherapy for their treatment regimens, so others have argued the possibility of limited improvement in the quality of life of some patients on biopharmaceuticals, considering the devastating side effects of chemo treatment. Another criticism of biopharmaceuticals is that, with cancer patients in particular, they normally provide an extension of their life of only a few months.
Several years ago, I saw Roy Vagelos, former CEO of Merck Pharmaceuticals, and heard him speak to others at Washington University in St. Louis about his views on medicines. And during his presentation, he stated something similar regarding the cost of biopharmaceuticals and asked as well about whether or not the value related to the cost of biopharmaceuticals is truly clinically beneficial for such a brief life extension of cancer patients in particular, for the most part.
An issue or issues are always associated with new paradigms and innovations. Yet there are only a few biopharmaceuticals out of many available with debatable benefits with the high price tag. It ends up being what the market will bear for what their makers charge others. Yet the real question is the clinical evidence behind biopharmaceuticals: If a biopharmaceutical stops tumor progression without harming such patients is clearly both safe and effective.
Another difference with biopharmaceuticals is that they are also regulated by what is called The Public Service Act, and are involved in authorizing the marketing of biopharmaceuticals.
Safety protocols regarding biopharmaceuticals are a mystery to me as well. What is known is that biopharmaceuticals have the potential to discover therapies to treat the cause of a particular disease state instead of treating such a disease only symptomatically. They set out to solve unmet clinical needs by science that has yet to be proven. Biopharmaceuticals save, enhance, and extend the quality of life of patients with terrible diseases, and over 250 million people have benefited from their products.
Yet presently, few biopharmaceutical companies are actually profitable. Also, with biopharmaceuticals, some years are better than others from a revenue and market share growth point of view. Yet like any business, some years are better than others, and biopharmaceuticals are anticipated to offer quite a bit to public health in the future, with a focus on cancer patients in particular.
The cost of developing a biopharmaceutical exceeds a billion dollars, with about a third actually making it to market. The market size of biopharmaceuticals is rapidly approaching 100 billion dollars a year, with average annual growth between 10 and 20 percent.
With cancer biopharmaceuticals, between70and 80 percent of them are believed to be prescribed off-label, so it will be interesting on how these drugs will be used in such disease states now and in the future.
So the future looks good for this industry, as biologics have tremendous marketing power along with superior therapeutic value.
Regardless of the challenges and flaws that exist with biopharmaceuticals and their makers, I’m pleased to see the results and realization of true innovation in pharmacology by taking a different path of drug development. Furthermore, I believe others should behave in a similar manner and be inspired by the biopharmaceutical companies and what they have done and continue to do for the benefit of patients regarding the issue of innovation.
