When you don't know the answer to a question, ask an expert. If the question is really big, ask more experts. If you have
a collection of difficult questions, run a poll of many experts. That, in effect, was the impetus for Eden Biodesign to survey
670 BioPharm International subscribers with questions as to what will be the development mechanism to achieve safe, effective, and cheap new medicines.

Before presenting survey results, which predict the future, we will assess the present state of biopharmaceutical development.
Thirteen of the 67 blockbuster drugs with annual sales over $1 billion are biopharmaceuticals.1 The growth in biopharmaceutical revenues has been running at over 20 percent compound annual growth between 1998 and 2003.2 This is significantly ahead of the rate for traditional pharmaceuticals. On a recent list of 100 great new investigational
drugs, 30 molecules can be classed as of the biotech variety.3 Investors are increasingly wary, particularly in Europe, having seen miserable returns on investment. Money is hard to come
by for small speculative biotechs. The expected surge in new biotech medicines as a result of mapping the Human Genome has
not yet materialized. In 2003, only 19 of the top 100 worldwide biopharmaceutical companies turned a profit.4 In short, biotech companies are under pressure from investors to deliver on the bottom line — sooner — not later.

However, there are reasons for optimism. One of the most promising is the concept of personalized medicine, or more properly,
the benefits arising out of pharmacogenetics (the genetics of drug metabolism and action) and pharmacogenomics or pharmacoproteomics
(gene or protein expression and drug action). The idea is to match treatments to the specific needs of patients, giving greater
clinical success, reducing unnecessary or ineffective treatments, and possibly reducing treatment costs.
Probably the best example of this principle is Herceptin, Genentech's breast cancer monoclonal antibody and its linked HER-2
receptor diagnostic test. For life threatening conditions such as breast cancer, the ability to get the appropriate treatment
"right the first time" has obvious benefits.
Introducing tests that significantly reduce the target patient population for a medicine obviously implies a small patient
market, and therefore either smaller revenues for pharmaceutical companies or major drug price increases. If the current market
for a treatment, for example asthma, were split into ten component parts — each one addressed by a different new drug — then
industry would have to develop ten new medicines instead of one for the same number of asthma sufferers. In the age of the
blockbuster, when massive sales are required to cover the costs of R&D failures, it looks like a big negative.
One recent estimate of the average cost of bringing a new molecular entity to the pharmaceutical market is $802 million5 and projected to be growing year by year at more than seven percent. These controversial findings triggered an independent
study in 2004 by the US Federal Trade Commission.6 Adams and Brantner reported that there was a higher average cost of $839-868 million.6 Admittedly, the cost varied from indication to indication (HIV-AIDS drug, $470 million, rheumatoid arthritis, $936 million)
and from company to company, ranging between $521 million and $2.119 billion per drug.) One fact is inescapable, the numbers
are large. If costs keep rising, the possibilities for better-targeted medicines aimed at smaller patient groups seem lower
and lower, excepting perhaps a few niche indications.
