Drug researcher reports that a new peptide fragment shows activity against influenza A including the H5N1 avian flu in vitro. The fragment is only 20 amino acid residues
New drug provides effective defence against bird flu
The above headline is misleading since the work has only been done in vitro and not in patients. I don’t have access to the actual article so I can’t comment on the amino acid sequence.
The peptide seems to prevent viruses from entering the cell and the survival rate for the animal models was 100%. While this is promising, there have been many cases of drugs showing excellent activity in animal models but never working in humans. It will be interesting to see if this develops and goes beyond the preclinical stage. Since this work comes from the University of Wisconsin-Madison, it would take a deal with a pharmaceutical or biotech company before it moves to the next stage.

One of the topics that the FDA will need to deal with is the whole topic of nanotechnology. It has been a hot topic recently due to an public meeting on this topic recently (Oct. 10, 2006).
United Press International - Health Business - Analysis: FDA comes up short on nanotech:
The above UPI report was released before the FDA meeting mentioned above. This paragraph caught my attention.
Taylor noted that the FDA’s budget would have to be increased by 50 percent to bring it up to its 1996 level. And the agency’s budget for next year won’t improve without action by Congress. President Bush’s 2007 proposed budget will increase the gap between responsibilities and capacity to 56 percent.
Given how important the FDA is (they oversee 25% of the gross national product) and how much work they have to do an increasing budget gap is cause for alarm. Especially in light of the recent rash of problems with spinach and lettuce which seems to indicate that there may not be enough oversight in this area. Add to this trying to keep up with the rapid advances in many areas particularly nanotechnology and you have a recipe for disaster.
There are at least 320 products using nanotechnology already on the market although many of these fall outside the purview of the FDA and about 200 products that would fall under the FDA’s rules are under development.
This is another example of science leading public policy when it comes to cutting edge technologies. I have some experience in this regard when I worked for a company developing polymer based drugs and educating the FDA on how the polymers were characterized. We had to educate some FDA folks as to what the analytical methods were we were using and how the technology worked and why we were using as well as other methods we tried that may not have worked and why they didn’t work.
FDA told to watch nanotech products for risks - Yahoo! News
The above story focuses on the fact that the FDA is ill equipped to deal with nantech products and the possible safety questions. The FDA has created an internal task force to look into nanotech and should have a report out in about nine months (mid-summer 2007). While I applaud them doing this, it seems to be quite late to the party. Nanotechnology has been popular for some time now and many products have been developed based on it. As quick search of Google news archive on nanotechnology shows articles back to March 1991.
A quick search for nanotechnology in Google trends shows searches for it being fairly flat but the really interesting fact to note is that the US does not even appear in the top 10 cities searching for this term. india occupies 6 of the top ten cities
Looking at the trends by country is even more revealing.
Another interesting tidbit is that Iran is number two for searching for the term nanotechnology. The US is down at the number 8 position. I’m not sure what to make of this but it is interesting.

Although not a merger or acquisition, this recent deal between Genentech and CGI Pharmaceuticals is still part of the activity in deals and mergers recently.
It is interesting that the deal seems to be broad in scoop covering discovery, development and manufacturing activities but more interesting is that the target has not been announced, only that it is in the area of oncology and autoimmune disorders. It is interesting not so much for what is says, but in the lack of details.
It includes a $25 million upfront payment and could come to $500 million if defined milestones are met over the next few years (the time frame was not spelled out).
Disclosure: I own a few shares of Genentech.

Today seems to be genetic testing day on this blog. Reuters had a report recently on a new genetic test that will likely find great use in oncology.
Test to predict response to chemotherapy drug | Top News | Reuters.com
This is exciting news. Basically, people with lung cancer that express a gene called ERCC1 will likely not respond to cisplatin. For these patients, other chemotherapy should be considered. While not proven yet in large studies, this is interesting and might in the future allow oncologists to select the proper treatment based on genetic testing. Since chemotherapy can have devastating side effects, it is important to get a treatment that has the highest probability of success for a given patient. If you are one of those who would not respond to a given drug, regardless of how effective it is in the given population, you would want to know that before going through a treatment with nasty side effects that won’t work for you. The fact that 75% of people respond doesn’t do you any good if you are in the 25% group. I also think that until recently there seemed to be much more emphasis on finding genes that indicated a person would respond to treatment rather than identifying those who would not respond. I think both are important and in the case of oncology identifying those who would not respond is very important to avoid going through a treatment that causes serious side effects but with no really benefit.
Another example is the HER2 and Herceptin. Women with early breast cancer who have higher levels of HER2 are at significant increase risk of the disease recurring and worst prognosis. However, these very patients respond quite well to treatment with Herceptin. This test is routinely used now for women with breast cancer.
I see this as the future of personalized medicine and not the process of making a specific compound for an individual. Finding out who will and who will not respond to a given treatment will be of tremendous importance to medicine in the 21st century.

Lately I’ve been thinking about genetic testing and its proliferation recently, especially those available by mail. A lot of those advertising are paternity related but others cover a wide variety of diseases.
CBS News recently had a good article about this.
Home Genetic Tests For Disease - CBS News
One of the problems with these mail-in testing is that, in the vast majority of cases, there is no counseling involved. What about the situation where a woman has sent in a DNA testing for breast cancer and the results come back that she has the gene in question. What does this mean to her? Does that mean she will definitely develop breast cancer? All of these are sure to be though about and without any access to genetic counseling how are they to get answers. Hopefully, most would turn to their primary care physician but some studies indicate they aren’t informed on what these various genetic testing results mean.
Seems that in some cases, these are like the old snake oil salesmen. They claim to test for all sorts of things but don’t disclose the limitations. There is also the worry of counseling if the results are potentially devastating. THen there is the fact that this industry is largely unregulated.
I think this area will be one that sees a dramatic increase in use in the next few years but like any tool, it needs to be used correctly. I can’t say, based on what I know now, that I think the mail order genetic testing is worth the cost, both monetary and psychological. This is another case where science is far ahead of public policy.

The AnorMED / Genzyme / Millennium saga continues. Now Genzyme has raised their hostile bid to acquire AnorMED. Genzyme’s new bid is $580 million.
Genzyme Raises Bid in AnorMed Fight: Financial News - Yahoo! Finance
AnorMED has until 4 PM PDT Oct. 11 to decide on Genzyme’s offer.
This one is interesting to watch and I personally think the smartest suitor will be the one who pulls out. This sort of bidding war only serves to help AnorMed and make it a very expensive proposition for whomever ends up acquiring them. This isn’t the end of this and it will be interesting to see how this plays out through the ned of the month.
As I have stated before, the merger and acquisition activity is showing no signs of slowing down any time soon. If anything, it is just now building up pa good head of steam.
Disclosure: I own a few shares of Millennium

By now everyone surely knows that Google purchased YouTube for a whooping $1.65 Billion (that’s with a B).
Google snatches up YouTube for $1.65B - Yahoo! News
First, as a podcaster I believe that video is indeed here to stay and not just a fad as some think. So, I do believe there is value in video over the Internet. However, I really don’t think a brand new company such as YouTube is worth that much. I am glad to see that Google did the deal as an all stock transaction. Maybe the fact that I think Google’s stock is way over valued makes up for part of the inflated price.
Some folks have said its about culture and not business. However, I think both need to keep in mind that they are in the business of making money especially since Google has shareholders they are accountable to. It is good to see that Google will allow YouTube to operate as an independent unit.
I realize Google wants to be a major player in video and their attempts to date have not been very successful. It is nice to see that they don’t have the “not invented here” mentality and are willing to go after a major player in the online video area.
The price paid is too much when you consider the amount of potentially copyrighted material on YouTube. While I realize that YouTube has managed to get a truce with Universal, there are many other media companies out there who are not as likely to settle in my opinion. Also, this transaction has served to put YouTube on the radar screen of other major media companies. Also, not that YouTube will soon be a part of Google, there are now much deeper pockets involved. Some analysts seem to think that media companies will now rush to make a deal with Google, but I fear the opposite is true. Too many old stream major media companies still do not understand the new economy and the impact of the Internet. They would much rather take legal action against anyone they feel has impinged on their territory.
Bottom line, I think it was a good acquisition for Google, but I think they vastly overpaid for it. Only time will tell if it was a wise move.

A recent article in the New York Times reports that the FDA may be more cautious in the after-math of Vioxx. I call this the Vioxx Effect.
New Sense of Caution at F.D.A. - New York Times
The article point to Avastin as an example where the FDA has asked for more data related to Genetech’s filing of the use of this drug in breast cancer. It is already approved for colon cancer. They also point to other drugs that have been approved in Europe but only have received an approvable letter here in the US. An approvable letter means the FDA would approve the drug if additional data is provided and the data supports the conclusions.
This is in contrast to the Institute of Medicine report that found the FDA is not doing its job adequately. So how can these both be true? I think a lot has to do with what material was looked at and how it was interrupted. I think both are correct. The FDA does need some changes and most importantly an increase in funding to adequately do its job. The recent food incidents of lettuce and spinach point to the lack of oversight in the food arena.
FDA Statement on Foodborne E. coli O157:H7 Outbreak in Spinach Update: Sunday, September 17, 2006
US FDA/CFSAN - Lettuce Safety Initiative
I do think though that the New York Times and Wall St. tend to focus more on the profitability and money side of things and ignore safety issues. I also think that some of the incidents of the drug industry not being more transparent has led to the overall reputation of both the industry and the FDA. As an example, Bayer recently failed to inform the FDA of data related to dangers with a heart surgery drug, Trasylol. It seems the company wanted to delay reporting these results until they could come up with other results to discount the negative study.
Bayer’s Duplicity on Drug Safety - New York Times
These sorts of incidents only play into the already widespread belief in the general public of the pharmaceutical industry being greedy and not having the best interest of patients at heart. This is an area where I truly believe reform is needed. Public disclosure of ALL studies and not selected studies should be required and there should be a centralized database for this that is accessible on the Internet.
So, both sides have valid point but here are the areas I think are in most need of reform.
1. Food Inspection: the FDA needs to be more proactive in the food area as evidenced by recent outbreaks of e. coli in spinach and lettuce.
2. Database to report publicly all studies preformed on a given drug. It should be required to be done in a timely fashion.
3. FDA needs the power to fine companies for violations. Currently there only have the power to pull a drug off the market. I’ve always thought it was strange and unreasonable that the FDA did not have this power. The EPA has this power and has been using it effectively for many years.
While I believe some reform is needed, I think it should be approached cautiously and without political ends in mind. If these areas are addressed, I think the FDA can bemuse a respected agency again in the near future.

In what I consider to be a very good development the FDA has now issued guidance to industry on developing cell-based viral vaccines. Right now, chicken egss are used and the process hasn’t changed in many years. Development of cell-based methods for manufacturing vaccines could increase the ability to produce vaccines.
FDA Issues Guidance to Industry for Development of Cell-Based Viral Vaccines
The New York Times also reported on this.
FDA Rules May Speed Flu - Shot Modernizing - New York Times
One of the important reasons for this is if the bird flu should happen to wipe out the chicken pollution, it would make producing vaccines using chicken eggs impossible and another method would need to be developed. It is good to see thought is going into this before something catastrophic happens.

The merging gold rush seems to be getting even crazier. Now Genzyme has extended their offer to buy AnorMED.
Genzyme Extends Deadline for Tender Offer to Acquire AnorMED Inc.: Financial News - Yahoo!
Finance
This is because Millenium has trumped Genzymes offer and there seems to be a bidding war going on for AnorMED.
Millennium offer beats Genzyme’s
Millenium Beats Genzyme, Gets AnorMED’s Stem Cell Drug: Financial News - Yahoo! Finance
And Anormed’s board is supporting Millenium’s bid whereas Genzyme was a attempted hostile acquisition.
ANORMED BOARD RECOMMENDS THAT SHAREHOLDERS ACCEPT MILLENNIUM OFFER
So this is definitely one to keep an eye on. I really think that the price for AnorMED is going to be too high and whoever ends up with them, will end up paying too much. Just my guess but a lot depends on how much risk the acquirer wants to take on in regards to the profitability of MOZOBIL, a stem cell mobilizer which stimulates stems cells out of the bone marrow and into the blood in circulating.
