PLANTATION, Fla., Jan. 25 /PRNewswire-FirstCall/ -- The following is
Part II of a letter from Charles A. Rice, President and CEO of Viragen,
Inc. (Amex: VRA; VRA.U; VRA.WS) and Viragen International, Inc. (OTC
Bulletin Board: VGNI). In addition to these comments, stockholders and
potential investors are referred to: the Company's SEC filings, including
Form 10-K and Form 10-Q (Annual and Quarterly Reports); press releases;
website; and other publicly disseminated information, which is available
free of charge upon request by contacting the Company. Part I of Mr. Rice's
letter was issued yesterday.
Dear valued Stockholder,
In Part I of my letter, I focused on our plans for Multiferon(R), which
will remain a priority for the Company due to its potential to generate
licensing and sales revenues in the immediate term. Now I will review our
plans for our anti-cancer candidates and the OVA(TM) System.
VG102: Anti-CD55 Antibody
In April 2005, we entered into an exclusive global license agreement
with Cancer Research Technology (CRT), the technology transfer arm of
Cancer Research UK, the largest not-for-profit cancer research organization
in the United Kingdom.
VG102 is an antibody to the CD55 antigen, which is over-expressed on up
to 80% of solid tumors, and may play an important role in hematological
cancers as well. The CD55 antigen acts as a protective mechanism, as it
effectively blocks the human body's immune system from destroying cancer
cells. VG102 binds to the antigen in such a way that reduces this
protective mechanism.
Because of its expected versatility in targeting many cancers, we
continue to receive many scientific and licensing inquiries related to
VG102. We are evaluating such early-stage opportunities, with the
understanding that this antibody's value should increase substantially, to
the extent we report additional positive in vitro and in vivo data,
supporting its progress into human clinical trials. Such studies are
currently ongoing with reports expected throughout the latter half of 2007.
Although early in development, VG102 truly has "blockbuster" potential as
an anti-cancer therapeutic, whether used alone or in combination therapy.
It is critical that we move this candidate through development as
effectively and expeditiously as possible.
The next milestone expected will be results reported from ongoing
binding specificity and efficacy studies later in 2007. If successful, we
will then advance into animal models to demonstrate efficacy in comparison
to a positive and negative control and to identify a most likely first
indication for the product. Toward the end of 2007, we would hope to be
ready to request scheduling of preliminary meetings with regulatory
agencies, including the U.S. Food and Drug Administration (FDA), for the
purpose of identifying appropriate toxicology and clinical studies
necessary for registration.
Again, the market opportunity for VG102 may very well eclipse all of
our other product candidates, so this is among our highest priorities. We
expect to raise the visibility of this program this year, as we anticipate
more frequent public communications, including press releases and
presentations at prominent cancer research conferences and biotechnology
industry meetings.
VG101: Anti-GD3 (R24) Antibody:
We have been working with Memorial Sloan-Kettering Cancer Center, as
part of a Collaborative Research Agreement, to further develop a monoclonal
antibody known in the literature as "R24" for the treatment of patients
with Stage IV melanoma. Viragen's obligation under this agreement has been
to develop humanized versions of the antibody that will be more suitable
than the original mouse form, for use as a human therapeutic. One of these
humanized VG101 constructs was expressed using our OVA(TM) System
technology.
Under this research agreement, Viragen has an exclusive option to
license this antibody for commercialization, and that option expires in
February 2007. Due to this imminent deadline, I will defer providing a
detailed update on VG101 until a final decision on whether to exercise this
option has been made in the coming weeks.
OVA(TM) System: Avian Transgenic Biomanufacturing
The concept of efficiently and cost-effectively producing therapeutic
proteins in the eggs of transgenic chickens is certainly revolutionary, and
the OVA(TM) System is receiving much attention with the successful
production of three functional protein-based drugs in hen's eggs thus far.
We continue to work closely with our partners at Roslin Institute, creators
of "Dolly the Sheep", to make this vision a reality. Earlier this week, we
reported the recovery of our third OVA(TM)-expressed protein, interferon
alpha-2a, and we expect to report on a fourth protein later this year.
With each OVA(TM)-expressed protein, we are evaluating the consistency,
quality and quantities of each product candidate expressed over multiple
generations of hens. These data will help us determine which types of
proteins are best suited for this manufacturing platform. The next
important step for our development plan will be to select a first product
candidate that we will take into production and into the registration
process.
While there is considerable industry and public interest in the OVA(TM)
System, this is still pioneering science with much to prove. It appears
likely that we should have an OVA(TM)-expressed product candidate at a more
advanced stage in clinical development, at least through the initial
regulatory processes in the U.S. or the EU, in order to generate realistic
licensing opportunities. This will require significant additional funding
and a number of years of work by our avian transgenics team. However, we
will strive to choose a first commercial product candidate that permits us
to take advantage of "expedited" regulatory processes that may be available
to us, so that the overall time required can be reduced.
VG106: A Novel Anti-Cancer Therapeutic
From our own databases, Viragen scientists have identified and filed
patent applications on potential new products based on our internal
research. The first of these, VG106, is the subject of a number of early
pre-clinical studies, and these data have been accepted for presentation at
a major upcoming cancer research conference. We are unable at this time to
disclose the identity of this product or the results, due to restrictions
imposed on presentation materials by this particular research organization.
We will report much more on this important new development in the coming
months.
In Closing:
The Management of Viragen expresses our sincere thanks to our
stockholders, for your patience and perseverance, even in the face of
dissatisfaction with our share valuation and past sales results. We have
positioned our projects and resources in expectation that 2007 and future
years will yield vastly improved results.
Our success is dependent upon our ability to secure adequate funding to
support our activities. We are exploring various alternatives including
financings, grants and new strategic initiatives. Additionally, we aim to
execute a funding strategy that will return Viragen to compliance with the
Amex's maintenance criteria, as we must do so by March 20, 2007 to remain
compliant with the plan we submitted to the Amex. While we intend to become
compliant by this deadline, our ability to do so will be dependent upon the
availability of funding on satisfactory terms and other factors outside of
our control, and we cannot provide assurances that our efforts in this
regard will be successful.
Our plans are ambitious, but also flexible, so that we can react
quickly should changes be necessary, and we are highly confident that we
will be able to build the kind of Company our stockholders can be proud of.
Sincerely yours,
Charles A. Rice
President and CEO
