It seems 2006 will be the year of finding out all kinds of things about drugs once though safe.
From Vioxx to everyday over-the-counter pain relievers we have seen unintended consequences raise its ugly head. The latest is the proton pump inhibitor class of compounds including Prilosec, Nexium, Prevacid, Aciphex and Protonix.
Heartburn drugs raise risk of hip fractures: study | Health | Reuters.com
The study is fairly large; 150,000 Britons over the age of 50. It found they had 13,556 hip fractures which is higher than expected. There was also a correlation to fractures with how long the drug was used and how high of a dose was taken. This is likely due to the drugs inhibiting calcium absorption. The good news is that by increasing calcium consumption these side effects can likely be overcome although studies would need to be done to prove that.
Here is a quote from the article.
“At this point, physicians should be aware of this potential association when considering (proton pump inhibitor) therapy and should use the lowest effective dose for patients with appropriate indications,” said study author Yu-Xiao Yang.
The report on the study, published in this week’s issue of the Journal of the American Medical Association, also said that elderly patients requiring long-term and high-dose drug therapy should consider increasing calcium intake.
I have always said that some of this problem is that pharma companies do not want to find out potentially negative information and avoiding doing studies that have a potential for a large downside but little to no upside. While I understand this from a business perspective, I think if there is any data that there could be unintended consequences, they should be investigated.

This Forbes article continues on what will likely be a major trend in 2007 for big pharmaceutical companies; downsizing if the sales force, especially internationally.
Analyst: Big Pharma Wields Axe - Forbes.com:
I’ve commented on this previously and think that it is something that has been a long time in coming. This report even believes that Pfizer who started this trend, may get rid of even more in its sales force. They have already let 2,200 people go but the article states that the international sales force of ~20,000 could be downsized by 30% or another 7,000 positions.
While I am always sorry to hear about job losses in the industry, this is an area I think could use it. With the lacking pipelines in many companies today and changes on how medications are purchased the need for them has diminished.

I spent some time working in Seattle and still keep a close eye on the biotech industry there. I was glad to see that Zymogenetics has submitted a new drug application (NDA) to the FDA for Thrombin. Thrombin is a genetically engineered human protein that inhibits bleeding.
The Seattle Times: Business & Technology: ZymoGenetics seeks OK to market drug
I do have a former colleague of mine who now works for Zymogenetics and I do like to see them prosper. Having said that, I am a little concerned that the patient size was fairly small; 411 patients, only half of which were on their drug, the other half received the standard of care; that being a cow derived product . They both worked equally well but those treated with the genetically engineered product did not develop antibodies to the protein; only 1.5% in the Thombin group vs 22% treated with the cow derived product.
The market for the drug is not huge; King Pharmaceuticals’ Thombin-JMI is about $250 million per year in sales. Zymo’s Thombin product will likely replace most of that and have some growth perhaps being a $400-500 a year product. Zymo’s product is being manufactured under contract with Abbott and there are no capacity limits as there is with the KIng Pharmaceutical product.

I hesitated to post about this but then decided I’d leave it to the readers to decide for themselves. This article in the LA Times concerning the FDA and a contract secured via a family connection.
Family tie helps win FDA contract - Los Angeles Times
Normally, I would think much about this but since both people involved were familiar with government contracting , it does appear that they should have known better. Here is the bachground from the article
WASHINGTON — The concerns at the office surfaced not long after their Las Vegas wedding.
Margaret “Margo” Burnette wasn’t pleased with the contractor handling an important data project at the Food and Drug Administration, where she held a senior position. For advice, she turned in summer 2004 to her new husband, Mark A. Boster.
Both had spent most of their careers dealing with government contracts. And Boster, she recalled, had been “ranting about this fabulous company.”
“I did ask Mark, ‘What was the name of that company?’ And I gave the name to my deputy.”
The sequence of events worked out well for Platinum Solutions Inc., of Reston, Va., for whom Boster was a paid advisor.
The FDA dismissed the first contractor and awarded the job to Platinum Solutions. By this fall, the small technology company had collected about $4 million from the project. Last month it won a new, related FDA contract, possibly worth millions more.
This seems like a clear conflict to me and is something that the FDA has come under scrutiny for in the past. Regardless of the final outcome (the FDA looked at it and no violation was found), even the appearance of conflict of interest should be avoided. The article paints a negative picture in my opinion especially since both were well aware of the rules but continue to say they had no regrets and no qualms about the situation. This sort of attitude is what bothers me. At the least, they should have said they wished they had handled it differently and been more upfront.

I always hate to report on drug failures but Telik recently had a major phase III failure for it cancer drug Telcyta and the stock plummeted over 70%.
Telik cancer drug fails trials; stock plummets - Yahoo! News
MercuryNews.com | 12/27/2006 | Telik stock takes a 71% hit
It is unclear why this occurred but the company claims that some patients who were dismissed from the study early may have been part of it. As usual the company is looking at the data to see if anything can be learned and to see if the drug can be possibly salvaged.
One of the things to keep in mind with cancer drugs is that unlike other drug categories, with cancer you have to compare against the standard of care. This means you are comparing your drug against a proven drug for a given indication.
I should also add that it wasn’t just one study; it was three phase III registration trials in ovarian and lung cancer as well as in combination with another drug for ovarian cancer. The fact that all three trials failed to meet its endpoints seems to point to the fact that the drug may not be working and should be discontinued.
One of the problems with small companies is their hesitancy to kill drugs early on. Too many times in my experience they throw good money after bad by trying to keep a project alive when it should have been killed a long time ago. This is especially true if the company only has a single compound in their pipeline. Fortunately, Telik has another drug in its pipeline called Telintra (TLK199) although it is in early stage trials.
It will be interesting to keep an eye on Telintra since this is the second drug to come out of their discovery platform called TRAP (target-related affinity profiling). If a second drug fails, it may point to the fact that this technology isn’t worthwhile.

Bristol-Myers Squibb (BMS) and Exelixis have reached an agreement to develop cancer drugs.
Exelixis, Bristol-Myers ink partnership:
BMS will use Exelixis’s drug discovery platform to come up with potential drug candidates. The deal involves $60 million in upfront payments and BMS can choose up to three candidates for $20 million each. the companies would co-develop and commercialize those compounds with Exelixis having the right to withdraw their co-development and co-promotion and would then only receive milestone and royalties instead of profit sharing.
I think this continues to show to me how desperate big pharma is for drug candidates. however, I do think BMS is smart in developing a partnership rather than a merger. I have said before that one of the problems with mergers is that it tends to stifle the innovation of small companies once they become a small part of a larger corporation. By making a deal, Exelixis gets to continue on its way with a good potential upside and BMS gets to choose a few good drug candidates to add to its pipeline. Also, since this is focus on cancer drugs it plays into one of BMS’s strengths.

The news of Lilly and Zyprexa (olanzapine) seemed to dominate the news last week and I felt it was a big enough story that I wanted to see how it developed and have a chance to read multiple reports before commenting on the story. What follows are the various stories and Lilly’s response and my comments on them.
Eli Lilly Said to Play Down Risk of Top Pill - New York Times
This NY Times article talks about the problem of significant weight gain in patients on the drug. The quotes below show that early on there were some concerns but that these were minimized and played down by Lilly sales reps.
Since then, Lilly has acknowledged Zyprexa’s effect on weight but has argued that it does not necessarily correlate to diabetes. But Zyprexa’s share of antipsychotic drug prescriptions is falling, and some psychiatrists say they no longer believe the information Lilly offers.
“From my personal experience, at first my concerns about weight gain with this drug were very significantly downplayed by their field representatives,” said Dr. James Phelps, a psychiatrist in Corvallis, Or. ‘Their continued efforts to downplay that, I think in retrospect, was an embarrassment to the company.”
Again, it is very difficult to PROVE cause and effect. Merck has taken the same approach in the Vioxx cases and this is a common strategy for drug makers when their drugs have problems. The weight gain is fairly easy to prove but does that lead to diabetes I think is the key question. While their maybe a lot of evidence SUGGESTING being overweight contributes to the odds of developing diabetes doesn’t necessarily cause it. I don’t think this negates the need to be safe and consider the down sided when developing drugs. Too often though, it is felt that since a drug is approved they need to do everything to defend the company or the product. I’ll have more to say on this aspect later in this post.
While the weight gain and the associated health problems are bad, if it controlled otherwise difficult cases of schizophrenia then the risk-benefit profile might still be worthwhile. However, the problem is the the drug appears to have been heavily promoted for off-label use. The following NY Time article talked about this.
Drug Files Show Maker Promoted Unapproved Use - New York Times
Off-label use is another of those controversial issues with regard to prescriptions drugs. I personally think the idea is okay but that many times it is taken advantage off. Many doctors rely on the information provided to them by the drug sales reps. Unfortunately, it has been shown that this system can be distorted and while the FDA may be able review the marketing documentation, they can’t regulate what these sales reps actually tell the doctor in their face to face contacts.
The issue of off-label marketing is controversial in the drug industry. Nearly every company is under either civil or criminal investigation for alleged efforts to expand the use of its drugs beyond the specific illness or condition for which they are approved.
I really think this is an area ripe for review. I personally would like to see this aspect of the system reformed and that may be occurring indirectly. Pfizer has greatly cut their sales force and other pharma companies are likely to follow suit. However this still doesn’t address the interaction itself. Maybe what is needed is an easy system for doctors to be able to access information from the FDA regarding the adverse events reported to the FDA. Doctors are already overworked in many cases and this system would need to be easily accessed and should also be available to consumers.
Lilly released a statement basically saying that a lot of this was taken out of context and represented only a small fractions of the documents available.
Eli Lilly and Company Statement Regarding Today’s New York Times Article
This too is a common strategy but in this case I think what has been seen is pretty damaging. If you look at other cases, sometimes companies try to bury the bad in a deluge of other information. Finding the nuggets contained therein then becomes a truly Herculean effort.
Too many times, pharma companies come out swinging which I feel just reinforces the view of the public that they are not concerned about patient safety and are primarily concerned about their profits. J. Scott Armstrong, a professor at the Wharton Business School at the University of Pennsylvania has studies this sort of situation in regard to Panalba an Upjohn drug that had problems back in the 1960’s and was finally removed in 1970.
The NY Times also had an editorial on this.
Playing Down the Risks of a Drug - New York Times (editorial)
Lilly contends that it has never promoted Zyprexa for unapproved uses and has always shown its marketing materials to the Food and Drug Administration, as required by law. Both claims ought to be tested in Congressional hearings that should focus on how well the industry complies with existing laws and how effectively the F.D.A. regulates the industry’s marketing materials.
While it may be legal it may not be moral. It is impossible to regulate what drug reps tell doctors. Even though the actual material is legal what is said or conved may be entirely different. Current think is that it is easier to get approval for a serious condition and then expand usage by “encouraging” off-label use. My understanding is that drug reps can leave “literature” on other uses for their drugs but can not “promote” for that.
Lilly also came out fighting by demanding the some documents where obtained illegally and should be returned to the court.

There were also other letters to the editor concerning Zyprexa.
Eli Lilly and the Dangers of a Drug (5 Letters) - New York Times
The problem is that no one wants to acknowledge the downside of their drugs. This is why labeling can be such a clash between the drug companies and the FDA. The labeling for drugs must be negotiated and I think this is a prime area where the FDA needs more authority. I’d like to see the FDA have the ability to add certain wording to labels based on strong scientific evidence regardless of the companies position.
Drug companies will say there is no proof of a given drug causing a certain problem but in many cases, this concern may have been brought up in internal meetings. However, it may be decided NOT to gather data that could be potentially damaging. I personally have sat in on meetings where it was decided NOT to do certain trials or look at certain aspects of drug because it might uncover potential problems. I have always argued strongly that in the long run it is best to have all the pertinent data but usually upper management and marketing come down that there is a large potential downside and no upside so these proposed studies are not done. It is the old head in the sand strategy; they would rather not know. Ignorance is truly bliss for them although I don’t think that can be maintained as a long term strategy.
An example of this is not comparing drugs to know which are most efficacious in which patients. This is something that needs to be done and could greatly benefit patients, but drug companies many times do not want to know the answer! They are afraid their product isn’t as good as some older less expensive drugs. While there have been some studies comparing various drugs these are far too few since it isn’t in the companies best interest. This is where the government could play a positive role in my opinion.
I think there is a need for adverse events reported not only to drug companies but directly to a reformed drug safety dept within the FDA. There also need strong authority to deal with such issues and the penalties should be strong enough to discourage this abuse. Drug companies have shown in several cases they can not be relied upon to provide un-biased information and many doctors are losing faith in drug reps.
There are always risks with drugs, something that I think is overlooked by many, including doctors and patients. Recently the FDA is wanting stronger worded language on pain relievers on the possibility of complication even with acetomenophen.
Many of these cases are the result of trying to protect something AT ALL costs! J. Scott Armstrong studies on the Panalba incident and some role playing he designed definitely shines
light on how these sorts of decisions are made.
The Panalba Case (pdf)
The Panalba Role Playing Case was designed to get participants to examine their behavior in a situation where their role can lead them to act in a socially irresponsible manner. A description of the case is provided along with instructions to the administrator. Much research has been done on this case, allowing subjects to compare their behavior with that of previous subjects.
Case of the Detrimental Drug: Implications of the Stakeholder Theory of Directorship
I highly recommend both of these as they give insight into why drug companies make their decisions and that it comes down to protecting their own corporation (they have a vested interest) rather than concentrating on patient safety.

The end of the year is always a time for reviewing what the year has held and making resolutions and predictions for 2007. With that in mind, I’d like to present my predictions of what may happen in the pharmaceutical and biotech industries in the year.
1. Biogeneric Regulations: The process for developing biogeneric regulations will get started in the US. This will likely be prompted by an act in Congress. I don’t expect for draft regulations for comment though to come out until sometime in early 2008. I think this is too bad and I personally would like to see regulations in place for comment before the end of 2007.
2. Mergers and Acquisitions: Mergers and big deals will continue in 2007 at full steam. Many of these will involve big pharma acquiring small biotech in order to fill their pipeline. Unfortunately, I don’t think the opportunities will pan out. The problem is that the principals involved in the small biotech that make it a success will not join the big pharma company. They will take their profits and most likley start another small biotech. The big pharma will not get the benefit that they tout to their investors for these purchases and will continue to pay too much for them on th fear that someone else will buy this small biotech instead.
3. Early Stage Deals: More deals will involve earlier and earlier stage products. Big pharma will be more willing to pay big prices for potential drug candidates at earlier stages of development in order to try and fill their pipelines.
4. DTC Advertising: Direct-to-Consumer (DTC) advertising will come under increasing attack and regulations will be enacted to prevent DTC ads in the first year of launching a new drug. Some companies have already said they will do this but I think it will become a matter of law.
5. The FDA: The FDA will be given additional powers to regulate drug post approval. This may include the ability to fine companies if they do not perform agreed upon studies within a certain timeframe.
6. The FDA; The FDA budget will be increase but only by a small amount: not enough to reflect what they actually have to accomplish.
7. Outsourcing: Although outsourcing will continue there will be a new move towards big pharma building R&D centers in China, and India.
8. Drug Imports: Congress will pass regulation to allow drug imports from a limited list of countries. This will be vetoed by the President.
9. Congress will discuss adding the ability for the Government to negotiate with drug companies for drugs covered by Medicare but legislation will fail.
10. Food Safety: Food safety will become an important topic and there will likely be at least one or two more national incidents involving more than 100 people. There will be talk in Congress of combining the USDA and the FDA food safety together but this will not happen.
Well, there they are in print and we’ll see at the end of 2007 how accurate these are.

Forbes has an article stating that other big pharmaceutical companies will cut their sales force.
Analyst: Big Pharma Wields Axe - Forbes.com:
While I think this will indeed occur across other companies starting in the New Year. I have always though there were way to many drug reps. The last several times I have visited my family doctor at a clinic with several doctors, there have been at least two or three drug sales reps in the waiting room. I know having been at Bristol-Myers Squibb shortly after their merger and the last group that was downsized was the sales force. Seems they were getting complaints that two or sometimes three drug reps were visiting the same doctors offices and hospitals peddling the exact same drugs sometimes one the same day.
While I hate to see anyone losing their jobs especially around the holidays, it certainly seems this down-sizing of sales forces has been a long time coming.
