Bio of CEO,
Stephen R. Seiler

Mr. Seiler joined Hybridon in 2001 as the company’s Chief Executive Officer.  Prior to joining Hybridon, Mr. Seiler was Executive Vice President, Planning Investment & Development for Elan Corporation from 1995 to 2001.  While at Elan, Mr. Seiler took part in and oversaw activities in a wide range of areas including acquisitions, divestitures and in/out licensing.

From 1991 to 1995 Mr. Seiler worked as an Investment Banker for Paribas Capital Markets in both London and New York.  He was founder of Paribas’ pharmaceutical industry investment banking group.  In that capacity, he initiated and worked on a wide variety of transactions including IPO’s, privatizations, M&A, debt and equity offerings and derivative transactions.

Mr. Seiler received a B.A. summa cum laude in History from the University of Notre Dame in 1977 and a J.D. (Honors) from Georgetown University in 1980.  He is a member of the bar in New York, Arizona and Missouri.

CEOCFOinterviews: Please explain to my readers, who is this company.

Mr. Seiler: Hybridon is a leading company in the discovery and development of therapeutic and diagnostic uses of synthetic DNA.  It is synthetic DNA chemistry, which runs through the core of all of our technologies.  More importantly, Hybridon is now in the position to accelerate the transformation of technology into drugs.   We’ve spent the last decade or so since the company’s founding building up our technology base.  We have reached a point now where we can begin the process of transforming our company’s technology into drugs and we are bringing those technologies and drugs to the clinic today.

CEOCFOinterviews: Why is it important to have this synthetic DNA?

Mr. Seiler: We actually have four technology platforms.  I’ll list them for you now and then talk more in detail about them later.  The first technology platform is Immunomodulatory Oligonucleotide technology, which I like to refer to as IMOTM for short.  There we use synthetic DNA to stimulate the body’s immune system.  The second technology platform is Drug Potentiation where we use DNA chemistry to increase the activity and potency of an existing, marketed chemo therapeutic.  The third technology platform in our therapeutic area is antisense.  This uses synthetic DNA to shut off the production of disease-causing protein at the cellular level.  Our fourth technology platform is functional genomics.  We can use antisense for functional genomics.  So, we are involved in a number of technology areas, but the key to what makes each of these work is synthetic DNA chemistry.

CEOCFOinterviews: I know this company has gone through a little bit of a transition here.  Let’s talk a little bit about that and what it has done for the company.

Mr. Seiler: You are, no doubt, aware that our first drug candidate GEM®91, which is a first generation antisense drug targeted toward HIV, was withdrawn from the clinic.  We started to look at the reasons for that failure and we discovered that the compound contained a DNA motif, which, in effect, the body recognized as a bacterial infection.  Consequently, the body was reacting with a very strong immune response to this drug which made it inappropriate as a therapeutic.  However, the insight as to what caused these problems led Hybridon to do two things.  First, we went back to the bench and created a second-generation chemistry for antisense which is more specific, has a longer life, reduced toxicity and is potentially orally available.   We believe this is a very exciting chemistry.  To the extent that antisense, as a science, will fulfill it’s potential, we believe that second generation chemistry is necessary. 

The other thing that we did following the withdrawal of GEM®91 was to explore what was causing the body’s immune system to react to GEM®91.  We decided to try and harness this activity in ways that may be beneficial, as opposed to toxic.  You can imagine there are certain types of situations when you want to up-regulate the body’s immune system, for example, in the treatment of cancer.  Cancer cells are recognized by the body’s immune system, but this recognition is notoriously weak.  In certain types of situations, giving a drug like an IMOTM for cancer therapy might be beneficial.  Likewise, if you want to give a vaccine and get a high antibody titer, up-regulating the immune system could give you a higher antibody titer than you might otherwise get.  Our IMOTM technology could be used similarly in conjunction with antibody therapies.  Finally, IMOTM technology may also be helpful in the treatment of asthma and allergies. 

So, what came out of the problems of our first clinical trial was, in effect, two technology platforms:  the first being second-generation antisense chemistry and the second being the IMOTM technology.

CEOCFOinterviews:  I was reading on your website that it’s actually working in combination with other drugs for the treatment of solid tumors.

Mr. Seiler: This is GEM®231. GEM®231, the company’s lead compound, is a second-generation antisense compound directed to solid tumors.  The antisense target is PKA.  What we have been doing in our clinical trials is combining GEM®231 with other existing chemotherapeutics and we are in the process of wrapping up Phase I/II trials with Taxol® and Taxotere®, and we hope to have those completed in the next couple of months.  In March of this year we announced the initiation of a clinical study combining GEM®231 with CPT-11.  The reason we started that trial is that we have seen in a number of animal models--and we’ve probably done over ten now--that the combination of GEM®231 and CPT-11 seems to increase the activity of CPT-11 in a very surprising and unique manner.  The animal data is exciting.  We have started a clinical trial to see if we can get the same result in humans.

CEOCFOinterviews: It’s becoming very exciting for you as you get into the additional phases.

Mr. Seiler: Absolutely, the way a company like Hybridon adds shareholder value is to take drugs through the phases of clinical development and each time you take a step forward, hopefully the market recognizes the value of that step in terms of share price appreciation.  So, the combination of moving our GEM®231 trials forward, as well as beginning the process of filling an IND for our lead IMOTM compound to take that into the clinic next year, will help raise our visibility on Wall Street and hopefully provide additional value for our shareholders.

CEOCFOinterviews: Where do you think the value will be in the future?  Will it be in partnerships or within the company itself?

Mr. Seiler: If you look at the value creation model for Hybridon, in the near term what we are going to do is create value for our shareholders in two ways.   We are going to continue the development on a very limited basis of our own compounds.  What I mean by that is we are going to focus on GEM®231 and our lead IMOTM compound and we will take those into the clinic ourselves.  But, more broadly, both our IMOTM technology platform, as well as our antisense technology platform, are susceptible to partnership arrangements.  For example, if you look at antisense, clearly the pharmaceutical industry has become a target rich environment as government, academic institutions, and pharmaceutical companies have spent billions of dollars to understand the human genome, looking for and finding genetic targets.   The challenge for the pharmaceutical industry, as it goes forward, is to turn all of these genetic targets into drugs.  We believe that our antisense technology can make us a key partner for many of these pharmaceutical companies in helping to turn these genetic targets into drugs.  So, in addition to taking our first two compounds forward ourselves, we expect to use our technology platforms as the basis for multiple collaborations and partnerships with the pharmaceutical industry.  That is the near and immediate future. 

Beyond, two to three years down the road, I fully recognize that Wall Street values drugs more than partnerships and licensing agreements.  So, as we build up our financial strength, as we build up our management strength, and as we build up clinical and regulatory abilities, I believe Hybridon will take more drugs into the clinic itself, but will also continue to partnership going forward.

CEOCFOinterviews: Someone looking at the company now, says wow look at all that is going on, but cash, obviously it is a value commodity for this company, how is it getting it’s revenues, how is it getting its money to stay afloat?

Mr. Seiler: Well, now, we have approximately two years worth of cash in the bank, our current burn rate is $12 to $15 million dollars a year.  We have about $30 million dollars in cash and an additional four and one-half million dollars due from one of our collaborations next year.  That puts us in a reasonably good financial position in the biotech space today.  Going forward we will be getting revenues if we enter into collaboration agreements:  up front fees, licensing milestones, and if our products work and see the light of day in the pharmaceutical world, royalties from collaborators.  But we are still an early stage company, primarily focused on research.  A product revenue stream, meaning a product in the market, is still many years away for us.

CEOCFOinterviews: You joined this company nine months ago, and you mentioned earlier about reorganizing the team there.   What was the biggest challenge you were faced with when you joined?

Mr. Seiler: The company had reached a very interesting point in its development.  It had spent about two years restructuring its balance sheet, selling off non-core assets and reorganizing its capital structure.  It successfully completed that process by mid-last year.  The challenge for Hybridon going forward is to take the value of its technology, which I believe is considerable, and begin to exploit it in ways which are meaningful.  We are beginning that process of exploitation and, as I said, that will take two forms:  developing some of our own clinical compounds like GEM®231 and our IMOTM compound, and to begin licensing broadly our technologies with other pharmaceutical and biotechnology companies.  I think this value extraction process is going to be important for Hybridon over the next year or two and hopefully will create more value for our shareholders.

CEOCFOinterviews: When you came aboard obviously you wanted new team members.  Do you feel you have a good management team in place today?

Mr. Seiler: We have a very good management team in place, and we have a strong scientific, development and financial staff.  Since I joined we have made some additional key hires in finance, preclinical development and in business development.  We are going to continue to hire as we move the company forward but I do believe we have the basis of a very solid team.  I am generally pleased with the progress we have made so far.  You never have enough good people, but I think we have an excellent group, and a very solid team.

CEOCFOinterviews: To a potential investor looking at this company, what would you say to them?

Mr. Seiler: We have a number of important milestones for the company going forward.  I can just briefly touch on some of them.  At the beginning of this year we had three clinical milestones, one of which we have already actually achieved.  Those three milestones are to begin a Phase I/II clinical trial combining GEM®231 and CPT-11.   I talked a little bit on that earlier.    We announced in the beginning of March that the trial had commenced, so we completed our first clinical milestone for the year.   Our second clinical milestone for the year will be to pick a lead compound for our IMOTM technology platform and begin the process of submitting an IND on that lead compound.  We hope in the next couple of months to make that announcement.  Our third clinical goal for the year will be to submit an IND on that lead IMOTM compound by year-end. 

On the financial side, our goals for the year are to complete two or three licensing agreements with pharmaceutical collaborators to validate our technology and provide some value inflection points for Wall Street.  Another financial goal for this year is to re-list Hybridon on a major exchange.  We are currently traded on the bulletin board but we would like to see if we could get to either AMEX or NASDAQ by year-end.  Although there are no guarantees, we are hopeful that we will be able to accomplish this. 

We have a number of important milestones for the company and clearly articulated corporate objectives.  This will allow shareholders to see what we are doing, to look at the scorecard and judge how we are delivering against what we had promised. 

CEOCFOinterviews: Would you work with companies overseas?

Mr. Seiler: We, in fact, have had some ongoing conversations with potential partners overseas.  My experience, though, having lived overseas, is that European partners are slower than American partners and Japanese partners are even slower than European partners.  Consequently, I would expect our first collaborations will come from North American companies, which tend to move much quicker than European or Japanese companies.

CEOCFOinterviews: But sometimes it seems to get the actual drug through it goes a little bit quicker overseas than it does here.

Mr. Seiler: It depends on the drug, and it depends on the country.   There are certain times when you can get products approved in Europe first.  But, again, I would expect our first product approvals and partnerships will come from North America.

CEOCFOinterviews: Any closing comments?

Mr. Seiler:  My objective today was to talk about our technology platform, which I have.  I also wanted to set forth our goals and objectives for this year. I think that is ultimately the basis of how people will judge our performance.  It is up to management to deliver the goods.  Clearly, Hybridon is what you would call a “story stock”.   The challenge for our company is to show that we can execute against our goals.  That is the scorecard by which we should be judged, and I expect to be judged by our shareholders.
