PROSPECTUS SUMMARY
This summary highlights information contained elsewhere in this prospectus.
It is not complete and may not contain all the information that you should
consider before investing in the common stock. You should read the entire
prospectus carefully, including the "Risk Factors" section.
The Company
CYTOGEN Corporation ("CYTOGEN" or the "Company") is a biopharmaceutical
company engaged in the development, commercialization and marketing of products
to improve diagnosis and treatment of prostate disease, of products for unmet
needs in the broader urological and oncology markets. CYTOGEN was incorporated
in Delaware in 1981. Unless the context otherwise indicates, as used herein, the
term "Company" refers to CYTOGEN and its subsidiaries, taken as a whole.
Our Products
We introduced to the market during 1997 our two principal products, each of
which have been approved by the U.S. Food and Drug Administration ("FDA"):
- ProstaScint(R) (kit for the preparation of Indium In111 Capromab
Pendetide).
ProstaScint has been approved as a diagnostic imaging agent for
prostate cancer, the most frequently diagnosed malignancy and
second leading cause of cancer death in men.
- Quadramet(R) Samarium Sm153 Lexidronam Injection).
Quadramet has been approved for the treatment of bone pain due to
cancers that have spread to the skeleton and that can be
visualized on a bone scan.
Our OncoScint(R) CR/OV imaging agent is also approved and marketed as a
diagnostic imaging agent for colorectal and ovarian cancer.
We believe that our products represent a significant improvement over
existing technologies because our products provide improved diagnostic
information and/or treatment in a site-specific manner with relatively low
levels of toxicity.
We also develop other products and technologies, both directly and through
subsidiaries, and have engaged in development efforts with other parties.
Our primary products in development are:
- Vaccines for prostate and other cancers utilizing the Company's
proprietary prostate specific membrane technology, or PSMA, in a
collaboration with Progenics Pharmaceuticals, Inc.;
- Other potential diagnostic and therapeutic applications of PSMA; and
- A bioinformatics platform designed to offer a database mapping
interaction between proteins to be accessed by a computer program for
use in drug discovery and research.
Research and Development
Historically, we have emphasized research and development of a broad array
of potential products, based on monoclonal antibodies and other technologies.
Having identified and commercialized products which we believe have substantial
potential, we have:
3
<PAGE>
- Conducted or sponsored clinical studies to evaluate existing
products in additional indications;
- Focused on development of technology with near term commercial
significance; o Reviewed all current research and development programs
to assess their commercial potential; and
- Recently curtailed basic research expenditures in order to allocate
resources toward implementing our business strategy.
Business Strategy
Our business strategy is directed primarily toward prostate and urological
diseases and, when opportunities arise, in the broader field of oncology and in
diagnostics. We plan to focus our efforts in areas in which we have experience.
Our approach calls for:
- Devoting our primary efforts to the marketing of ProstaScint and
Quadramet to increase revenue and achieve profitability;
- Expanding the use of ProstaScint and other products into foreign
markets;
- Developing products utilizing our proprietary technology;
- Expanding our current product portfolio through the continued
in-licensing of additional products and related technologies, in the
same manner as Quadramet;
- Establishing strategic alliances;
- Acquiring other companies with related or complementary products,
technologies and/or services.
We cannot predict, however, whether we can accomplish these objectives or
whether accomplishment of these objectives will lead to new commercially viable
products or technologies. In addition, our efforts to develop or acquire new
products depend on our available resources, our ability to commit resources to
potential products or strategic activities without unduly impacting current
operations or financial results, and whether or not such activities in the near
term would affect the marketing of our products or the efforts of management to
commercialize the Company successfully.
Restructuring Activities
During 1998 and early 1999, we reviewed our assets and business prospects
to determine which projects demonstrated adequate potential for a continued
investment of corporate resources. As a result of this review, we:
- Terminated our ALT program.
Our subsidiary Cellcor, Inc. ("Cellcor") had been developing
Autologous Lymphocyte Therapy ("ALT") for the treatment of
metastatic renal cell carcinoma ("mRCC"), a life threatening
kidney cancer for which there are no adequate therapies. We had
planned to submit a Biologics License Application for ALT.
Cellcor completed pivotal Phase III clinical trials of ALT in
mRCC patients in January 1997. Although we believe the results of
the trials are favorable, ALT was not considered a priority for
allocation of available resources. We halted our preparation for
submission of the Biologics License Application and closed our
Cellcor facility in September 1998.
- Sold our interest in Targon Corporation.
Our review determined that the projects under development by
Targon Corporation ("Targon") were not consistent with our
corporate strategies. During August 1998, we sold our interest in
Targon to our partner in the venture, Elan Corporation plc
4
<PAGE>
("Elan") for $2 million in cash. In addition, we received $2
million from Elan in exchange for a convertible promissory note.
- Sold our manufacturing facility.
We determined that outsourcing manufacturing of the Company's
products would be more economical and consistent with our
strategies. During early January, 1999, we sold our manufacturing
facility to Bard Bio Pharma L.P., a subsidiary of Norwalk, CT
based pharmaceutical company Purdue Pharma L.P. We received $3.9
million in cash for the assets in the facility, and the lease to
the building. We also signed an agreement with Purdue to share
space in the building to continue to manufacture our ProstaScint
and OncoScint products at the same location. Employees involved
in manufacturing currently remain CYTOGEN employees, but Purdue
will pay for their labor costs except while they are working on
our products.
- Reduced expenses.
We have downsized the workforce by eliminating positions which
were no longer critical to our strategic plans and have curtailed
expenses for basic research.
Recent Developments
On June 15, 1999, we reacquired the rights for immune therapy to our
prostate specific membrane antigen ("PSMA") technology by acquiring Prostagen,
Inc., which had sublicensed PSMA from us for prostate cancer immune therapy in
1996. We also acquired other assets held by Prostagen, including approximately
$550,000 in cash, a minority ownership in Northwest Biotherapeutics, Inc., which
is developing PSMA for cell therapy, and a contract with Velos, Inc. for
marketing a cancer patient software management program for hospitals and health
care payors. In exchange, we issued 2.5 million shares of our common stock,
valued at $1.00 per share, and will issue up to an additional $4.5 million worth
of our common stock (valued at the time of issuance) if milestones are achieved
in the PSMA development program.
On June 15, 1999, we also entered a joint venture with Progenics
Pharmaceuticals, Inc. to develop PSMA for immune therapy, emphasizing cancer
vaccines for prostate and possibly other cancers. The project will be owned
equally by us and Progenics. Progenics will fund development through the filing
of an Investigational New Drug Application with the U.S. Food and Drug
Administration. We believe this first step will last approximately two years.
After and if that step is achieved successfully, we and Progenics will share the
costs of clinical trials. We will have exclusive North American marketing rights
on products developed by the venture. We will receive $2 million in payments for
licensing this technology to the venture. $500,000 has been received and the
balance will be paid in installments through December 31, 2001. We can not give
any assurance that this program will result in products reaching the market or
being successful.
In June of 1999, we reacquired rights to our ProstaScint and OncoScint
products in Canada, which had been licensed to Faulding (Canada), Inc. We also
agreed with Berlex Laboratories, Inc., the North American marketing partner for
our Quadramet product, that we would market Quadramet in Canada. We did not pay
for either of these agreements. OncoScint and Quadramet are approved by the
Canadian Health Care Branch; ProstaScint is under expedited review. We believe
these products may be marketed to major cancer centers in Canada and will not
require the same level of resources as for U. S. marketing. However, we can not
be certain that ProstaScint will be approved in Canada, that these products will
be reimbursable under the Canadian health care system, or that they will be
accepted by physicians.

RISK FACTORS
Prospective investors in the common stock offered hereby should carefully
consider the following risk factors, in addition to the other information
contained in this prospectus. This prospectus contains forward-looking
statements which involve risks and uncertainties. Our actual results could
differ materially from those anticipated in these forward-looking statements as
a result of certain factors, including those set forth in the following risk
factors and elsewhere in this prospectus.
History of Operating Losses and Accumulated Deficit
We have a history of operating losses as follows:
Operating Net Profit (Loss) to
Losses Common Stockholders
Three months
ended March 31, 1999 ($ 1,694,000) $ 1,657,000
Year Ended December 31, 1998 ($ 15,915,000) ($ 13,271,000)
Year Ended December 31, 1997 ($ 31,027,000) ($ 32,064,000)
The operating losses were due in part to limited revenues and to various
expenditures, including:
- Research and development activities;
- Acquiring of complementary products and technologies;
- Seeking regulatory approvals for our products;
- Preclinical and clinical studies related to our products;
- Preparing of submissions to the United States Food and Drug
Administration;
- Developing of sales, marketing, manufacturing and distribution
channels;
- Developing of internal manufacturing capabilities relating to
ProstaScint; and
- General and administrative expenses.
We expect to incur operating losses in the future due primarily to:
- Continuing product development;
- Acquiring, developing and commercializing complementary products
and technologies; and
- Expansion of our sales and marketing activities.
As of March 31, 1999, we had an accumulated deficit of approximately $300
million.
6
<PAGE>
Uncertainty of Profitability
Our ability to achieve and maintain profitability is highly dependent upon
the successful commercialization of our products, including Quadramet and
ProstaScint. Our profitability may also depend on success with PSMA and with
AxCell Biosciences. There can be no assurance that we will ever be able to
successfully commercialize our products or that we will ever achieve
profitability.
Fluctuating Results of Operations
Our results of operations have fluctuated on an annual and quarterly basis
and may fluctuate significantly from period to period in the future, due to,
among other factors:
- Variations in revenue from sales of and royalties from our
products;
- Timing of regulatory approvals and other regulatory announcements
relating to our products;
- Variations in our marketing, manufacturing and distribution
channels;
- Timing of the acquisition and successful integration of
complementary products and technologies;
- Timing of new product announcements and introductions by the
Company and its competitors, and
- Product obsolescence resulting from new product introductions.
Many of these factors, and others not listed above, are outside our
control. Due to one or more of these factors, our results of operations may fall
below the expectations of securities analysts and investors in one or more
future quarters. If this happens, the market price of our common stock could be
materially and adversely affected.
Need for Additional Capital
We have incurred negative cash flows from operations since inception, and
have expended, and will need to expend, substantial funds to complete our
planned product development efforts, including:
- Acquisition of products and complementary technologies;
- Research and development;
- Clinical studies and regulatory activities; and
- Expansion of our marketing, sales and distribution activities.
In addition to the above requirements, we expect that we will require additional
capital either in the form of debt or equity, irrespective of whether and when
we reach profitability, for the following activities:
- Working capital;
- Acquisitions of additional products and technologies; and
- Further product development.
7
<PAGE>
Our future capital requirements and the adequacy of our available funds
depend on numerous factors, including:
- Successful commercialization of our products;
- Acquisition of complementary products and technologies;
- Magnitude, scope and results of our product development efforts;
- Progress of preclinical studies and clinical trials;
- Progress of regulatory affairs activities;
- Costs of filing, prosecuting, defending and enforcing patent claims
and other intellectual property rights;
- Competing technological and market developments; and
- Expansion of strategic alliances for the sale, marketing and
distribution of our products.
We currently expect that our existing cash, together with decreased
operating costs, and revenues generated by product sales and royalties, and the
proceeds from this offering, will be adequate to fund our operations into 2000.
We can not give assurance that we will not consume our available capital
resources before that time. If we experience unanticipated cash requirements, we
may require additional capital to:
- Fund operations;
- Continue research and development programs;
- Continue pre-clinical and clinical testing of potential products;
or
- Commercialize any products that may be developed.
Possible Unavailability of Other Financing
There can be no assurance we will be able to obtain additional financing on
acceptable terms, if at all. We may seek to raise additional capital through
public or private offerings of equity or debt or through collaborative
agreements, strategic alliances with corporate partners and others, or through
other contractual arrangements with third parties. We may receive additional
funds upon the exercise of common stock purchase warrants and stock options, but
there can be no assurance that any warrants or stock options will be exercised
or that the amounts received will be sufficient to meet our capital needs. If
adequate funds are not available, we may be required to delay, further scale
back or eliminate one or more of our development programs or certain aspects of
our operations, or to obtain funds by entering into arrangements with
collaborative partners or others that may require us to relinquish rights to
certain of our products, product candidates, technologies or potential markets,
that we would otherwise not relinquish. If adequate funds are not available, our
business, financial condition and results of operations will be materially and
adversely affected.
Possible Dilution or Requirement to Comply with Covenants
Additional equity financing may result in substantial dilution to
shareholders, and debt financing may limit our ability to declare dividends, or
may require us to comply with covenants that would alter the way we conduct
business.

<PAGE>
Dependence on Market Acceptance of ProstaScint and Quadramet for Revenues
None of our products has a significant history of revenues. ProstaScint and
Quadramet were introduced to the market during the first half of 1997 and are
expected to account for a significant percentage of our product-related revenues
in the foreseeable future. For the year ended December 31, 1998, revenues from
ProstaScint and Quadramet accounted for over 91% of our product related
revenues.
Because these products contribute the majority of our revenues, our
business, financial condition and results of operations depend on their
acceptance as safe, effective and cost efficient alternatives to other available
treatment and diagnostic protocols by the medical community, including:
- health care providers, such as hospitals and physicians
- third-party payors, including Medicare, Medicaid, private insurance
carriers and health maintenance organizations
Market Acceptance of ProstaScint
ProstaScint is marketed in the United States by the urological division of
C. R. Bard, Inc. ("BARD"), with CYTOGEN retaining co-marketing rights. We
believe that efforts to market ProstaScint to physicians and hospitals have been
well received, based on increasing sales, statements by physicians to our
employees as to the benefits of ProstaScint and presentations on ProstaScint by
physicians at medical association meetings. However, training by physicians,
technicians and other health care professionals is required before certain of
our products can be used for diagnosis or therapy. In order to use ProstaScint,
our customers, including technologists and physicians, must successfully
complete our Partners in Excellence Program ("PIE(TM) Program"), a proprietary
training program designed to promote the correct acquisition and interpretation
of ProstaScint images. This approach is, therefore, technique dependent and
requires a learning commitment on the part of users. There can be no assurance
that additional physicians will make this commitment or otherwise accept this
product as part of their treatment practices.
CYTOGEN has a program dedicated to providing information to and resolving
issues with managed care organization ("MCOs") relating to reimbursement. BARD
is obligated to market ProstaScint to MCOs, but has not yet implemented a
significant program in this area. Failure to market ProstaScint to MCOs could
hinder acceptance or reimbursement, although we cannot quantify what impact, if
any, this marketing effort could have on sales of ProstaScint.
Market Acceptance of Quadramet
Berlex Laboratories, Inc. ("Berlex") is responsible for the marketing of
Quadramet in the United States, including marketing to MCOs, by an agreement
entered in October 1998. Their marketing efforts began in the first quarter of
1999. We can not give any assurance that Berlex will be able to successfully
market Quadramet, or that this agreement will be profitable for the Company.
CYTOGEN recently obtained marketing rights to Quadramet in Canada, but has not
yet implemented a selling program. We can not give any assurance that the
product can be marketed effectively in Canada, or that it will contribute
significantly to the Company's revenues.
We have licensed the rights to Quadramet from The Dow Chemical Company
("Dow"). Such rights are currently limited to North and Latin America with
respect to currently approved indications. We also hold a license from Dow for
use of Quadramet in treatment of refractory rheumatoid arthritis in North and
Latin America and in other countries, including European countries and Japan.
9
<PAGE>
There can be no assurance that Quadramet will be accepted in the United States
and Canada, where the product is currently approved. We also can not give any
assurance that Quadramet will be accepted in any markets outside the United
States and Canada, or approved for additional indications in any locations, due
to the influence of established medical practices and other social and economic
factors beyond our control.
Accordingly, there can be no assurance that ProstaScint or Quadramet will
achieve market acceptance on a timely basis, or at all. The failure of
ProstaScint or Quadramet to achieve market acceptance would have a material
adverse effect on the Company's business, financial condition and results of
operations.
Risks Relating to Potential Additional Cuts in Company Programs
We are reviewing and prioritizing programs, and there can be no assurance
that we will not cut programs to conserve capital. After reviewing and
prioritizing our business opportunities, we have ceased various developmental
and research programs, including submission of a Biologics License Application
for ALT. In addition, we have ceased basic research in our Genetic Diversity
Library ("GDL") program. Any additional cuts would increase our dependence on
our remaining programs, and would increase the risk from such programs to the
Company as a whole, which could materially and adversely affect our chances of
obtaining profitability. While we plan to allocate our resources to those
programs with the greatest potential to contribute to a sound financial and
operating position, there can be no assurance that we will be successful in
doing so.
Dependence on our Collaborative Partners
Our success depends in significant part upon the success of our
collaborative partners. We have entered into the following agreements for the
sales, marketing, distribution and manufacture of our products, product
candidates and technologies:
- Sub-license and marketing agreement with Berlex relating
to the Quadramet technology that we have licensed from
Dow. Berlex is responsible for marketing, selling and
arranging manufacturing and distribution of Quadramet in
the United States, Canada, and Latin America. This
agreement expires on the later of December 20, 2014 or
upon the expiration of the patents covering Quadramet.
- Co-promotion agreement with BARD, granting BARD's
Urological Division the exclusive right to market
ProstaScint to urologists; and
- Agreement for manufacture of Quadramet by The DuPont
Pharmaceuticals Company (formerly the radiopharmaceuticals
division of the DuPont Merck Company, "DuPont").
- A joint venture with Progenics Pharmaceuticals, Inc. for
the development of PSMA for immunotherapy for prostate and
other cancers.
Because our collaborative partners are responsible for certain of our sales,
marketing, manufacturing and distribution activities, these activities are
outside our direct control. There can be no assurance that our partners will
perform their obligations under these arrangements with the Company. In the
event that our collaborative partners do not successfully market and sell our
products, or breach their obligations under the above agreements, the successful
commercialization of Quadramet and ProstaScint would not be achieved or would be
delayed, and new product development could be inhibited, which could have a
material adverse effect on our business, financial condition and results of
operations.
10
<PAGE>
There can be no assurance that we will be able to maintain our existing
collaborative arrangements; if they expire or are terminated, there can be no
assurance that they will be renewed, or that new arrangements will be available
on acceptable terms, if at all. In addition, there can be no assurance that any
new arrangements or renewals of existing arrangements will be successful, that
the parties to any new or renewed agreements will perform their obligations
thereunder, or that any potential collaborators will not compete with us.
There can also be no assurance that our existing or future collaborations
will lead to the development of product candidates or technologies with
commercial potential, that we will be able to obtain proprietary rights or
licenses for proprietary rights for our product candidates or technologies
developed in connection with these arrangements, or that we will be able to
ensure the confidentiality of proprietary rights and information developed in
such arrangements or prevent the public disclosure thereof.
Limited Sales, Marketing and Distribution Capabilities
We have limited internal sales, marketing and distribution capabilities. We
depend on Berlex for the sales, marketing and distribution of Quadramet in the
United States, and on BARD for the sale and marketing of ProstaScint. In
locations outside the United States, we have not established a selling presence.
If we are unable to establish and maintain significant sales, marketing and
distribution efforts, either internally or through arrangements with third
parties, our business, financial condition and results of operations could be
materially adversely effected.
We have limited marketing history for our products:
- ProstaScint was approved for marketing by the FDA in
October 1996, and commercially launched in February 1997.
ProstaScint sales have experienced growth since product
launch. However, there can be no assurance that such
growth will continue; and
- Quadramet was approved for marketing by the FDA in March 1997 and
launched by DuPont in June 1997. Quadramet sales during the
period from initial launch were below the levels of minimum
royalty payments we recorded under our agreement with DuPont.
Growth during early months was limited by the need for hospitals
to obtain license amendments under federal and state law to
receive and handle this new radioactive product. In addition,
initial marketing efforts by DuPont were directed primarily to
nuclear medicine physicians who directly administer the product
to patients. While we believe this approach was necessary to
generate product understanding, marketing to primary caregivers
for likely candidates for treatment with Quadramet is necessary
for extensive penetration into the market. Berlex maintains a
sales force which calls on the physician oncological community;
however, there is no significant experience with sales efforts
for Quadramet and there can be no assurance that sales efforts
will be successful.
The failure of our marketing efforts to achieve commercial success would
have a material adverse effect on our business and results of operations.
Risks Associated with Manufacturing; Third-Party Manufacturers' Dependence on
Single Source Suppliers; Need to Comply with Manufacturing Regulations
Our products must be manufactured either internally or through third-party
manufacturers in compliance with regulatory requirements and at acceptable
costs.
11
<PAGE>
While we believe that our manufacturing operations currently address our
needs for the production of our products, there can be no assurance that we will
be able to continue to manufacture, arrange for manufacture on a commercially
reasonable basis, or successfully outsource the manufacturing of our products.
If we are unable to successfully manufacture or arrange for the manufacture of
our products and product candidates, there would be a material adverse effect on
our business, financial condition and results of operations.
Quadramet is manufactured by DuPont pursuant to an agreement with both
Berlex and CYTOGEN. Certain components of Quadramet, particularly Samarium-153
and EDTMP, are provided to DuPont by outside suppliers. Due to radioactive
decay, Samarium-153 must be produced on a weekly basis. On one occasion, DuPont
was unable to manufacture Quadramet on a timely basis due to the failure of a
supplier to provide Samarium-153. If DuPont cannot obtain sufficient quantities
of such components on commercially reasonable terms, or in a timely manner, it
would be unable to manufacture Quadramet on a timely and cost-effective basis
which could have a material adverse effect on our business, financial condition
and results of operations. Alternative sources for these components may not be
readily available. If DuPont were to lose its sources of supply for such
components, production of Quadramet would be interrupted, which could have a
material adverse effect on our business, financial condition and results of
operations.
The Company and its third party manufacturers are required to adhere to FDA
regulations setting forth requirements for current Good Manufacturing Practices
("cGMP") and similar regulations in other countries, which include extensive
testing, control and documentation requirements. Ongoing compliance with cGMP,
labeling and other applicable regulatory requirements is monitored through
periodic inspections and market surveillance by state and federal agencies,
including the FDA, and by comparable agencies in other countries. Failure of the
Company and its third-party manufacturers to comply with applicable regulations
could result in sanctions being imposed on us, including fines, injunctions,
civil penalties, failure of the government to grant premarket clearance or
premarket approval of drugs, delays, suspension or withdrawal of approvals,
seizures or recalls of products, operating restrictions and criminal
prosecutions.
Risks Associated with Reimbursement by Third-Party Payors
Our business, financial condition and results of operations will continue
to be affected by the efforts of governments and other third-party payors to
contain or reduce the costs of healthcare through various means. There have
been, and we expect that there will continue to be, a number of federal and
state proposals to implement government control of pricing and profitability of
therapeutic and diagnostic imaging agents such as our products. In addition, an
emphasis on managed increases possible pressure on pricing of these products.
While we cannot predict whether such legislative or regulatory proposals will be
adopted or the effects such proposals or managed care efforts may have on our
business, the announcement of such proposals and the adoption of such proposals
or efforts could have a material adverse effect on our business, financial
condition and results of operations. Further, to the extent such proposals or
efforts have a material adverse effect on other companies that are prospective
corporate partners for the Company, our ability to establish strategic alliances
may be materially and adversely affected.
Sales of our products depend in part on the availability of reimbursement
to the consumer from third-party payors, including Medicare, Medicaid, and
private health insurance plans. Third-party payors are increasingly challenging
the prices charged for medical products and services. There can be no assurance
- ---that our products will be considered cost-effective and that reimbursement to
consumers will continue to be available, or will be sufficient to allow us to
sell our products on a competitive basis. Approval of our products for
12
<PAGE>
reimbursement by a third party payor may depend on a number of factors,
including the payor's determination that our products are clinically useful and
cost-effective, medically necessary and not experimental or investigational.
Reimbursement is determined by each payor individually and in specific cases.
The reimbursement process can be time consuming and costly. If we cannot secure
adequate third party reimbursement for our products, there would be a material
adverse effect on our business, financial condition and results of operations.
Intense Competition in the Biotechnology and Pharmaceutical Industries
The biotechnology and pharmaceutical industries are subject to intense
competition from large pharmaceutical, biotechnology and other companies, as
well as universities and research institutions.
Many of these competitors have, compared to us, substantial advantages with
respect to their:
- Financial, marketing, sales, manufacturing, distribution and
technological resources;
- Sales and marketing expertise;
- Distribution channels;
- Experience in establishing third-party reimbursement for their
products;
- Research and development expertise;
- Experience in conducting clinical trials;
- Experience in regulatory matters;
- Manufacturing efficiency; and
- Name recognition.
Due to this intensely competitive environment, there can be no assurance
that we will be able to compete effectively against such existing or potential
competitors or that competition will not have a material adverse effect on our
business, financial condition and results of operations.
Quadramet competes with other more traditional treatments or therapies,
such as:
- External beam radiation;
- Chemotherapy agents;
- Narcotic analgesics; and
- Radiopharmaceuticals.
In addition, certain of our competitors may be in the process of seeking
FDA or foreign regulatory approval for their own products, which compete
directly or indirectly with ours.
We are highly dependent upon proprietary technology and seek to protect
such technology through a combination of patents, licenses and trade secrets. We
have applied for, obtained and licensed patents for certain proprietary aspects
of our technology and processes in the U.S. and other countries. We are
particularly dependent upon the enforceability of our license with Dow with
respect to Quadramet. There can be no assurance that our owned and licensed
patents will prove to be enforceable or that additional patents will be issued.
Neither can assurance be given that the technologies we use do not infringe upon
the proprietary rights of others, although we are not aware of any such
infringement or any adverse claim. Insofar as we rely in part on trade secrets
and unpatented know-how to maintain our competitive position, there can be no
assurance that others will not independently develop similar or superior
technologies or that our trade secrets and know-how will not become known to
others. We could incur substantial costs in seeking enforcement of our patents
13
<PAGE>
against infringement or preventing unauthorized use of our trade secrets by
others, or in defending patent infringement claims brought against the Company.
Our success depends, in part, on our ability, and the ability of our
collaborators or licensors, to obtain protection for products and technologies
under United States and foreign patent laws, to preserve trade secrets, and to
operate without infringing the proprietary rights of third parties. Because of
the substantial length of time and expense associated with development of new
products, the biopharmaceutical industry places considerable importance on
obtaining, and maintaining, patent and trade secret protection for new
technologies, products and processes. We have obtained rights to certain patents
and patent applications and may obtain or seek rights from third parties to
additional patents and patent applications. There can be no assurance that
patent applications relating to our products or technologies will result in
patents being issued, that any issued patents will afford us adequate
protection, or that such patents will not be challenged, invalidated, infringed
or circumvented. Furthermore, there can be no assurance that others have not
developed, or will not develop, similar products or technologies that will
compete with ours without infringing upon our intellectual property rights.
Legal standards relating to the scope of claims and the validity of patents
in the biopharmaceutical industry are uncertain and still evolving, and no
assurance can be given as to the degree of protection that will be afforded any
patents we are issued or license from others. There can be no assurance that, if
challenged by others in litigation, the patents we have been assigned or have
licensed from others will not be found invalid. There can be no assurance that
our activities would not infringe patents owned by others. Defense and
prosecution of patent matters can be expensive and time-consuming and,
regardless of whether the outcome is favorable to us, can result in the
diversion of substantial financial, management and other resources. An adverse
outcome could:
- Subject us to significant liability to third parties;
- Require us to cease any related research and development activities
and product sales; or
- Require us to obtain licenses from third parties.
No assurance can be given that any licenses required under any such patents
or proprietary rights would be made available on terms acceptable to us, if at
all. Moreover, the laws of certain countries may not protect our proprietary
rights to the same extent as United States law.
Our success also depends on the skill, knowledge, and experience of our
scientific and technical personnel. To help protect our rights, we require all
employees, consultants, advisors and collaborators to enter into confidentiality
agreements that require disclosure, and in most cases, assignment to us, of
their ideas, developments, discoveries and inventions, and that prohibit the
disclosure of confidential information to anyone outside the Company. There can
be no assurance, however, that these agreements will provide adequate protection
for our trade secrets, know-how or other proprietary information in the event of
any unauthorized use or disclosure.
Product Development
Product development involves a high degree of risk. There can be no
assurance that the product candidates we develop, pursue or offer will prove to
be safe and effective, will receive the necessary regulatory approvals or will
ultimately achieve market acceptance. These product candidates will require
substantial additional investment, laboratory development, clinical testing and
regulatory approvals prior to their commercialization. There can be no assurance
that we will not experience difficulties that could delay or prevent the
successful development, introduction and marketing of new products. If we are
14
<PAGE>
unable to successfully develop and commercialize products on a timely basis or
at all, or achieve market acceptance of such products, there could be a material
adverse effect on our business, financial condition and results of operations.
Before we obtain regulatory approvals for the commercial sale of any of our
products under development, we must demonstrate through preclinical studies and
clinical trials that the product is safe and efficacious for use in each target
indication. The results from preclinical studies and early clinical trials may
not be predictive of results that will be obtained in large-scale testing, and
there can be no assurance that the our clinical trials will demonstrate the
safety and efficacy of any products or will result in marketable products. A
number of companies in the biotechnology industry have suffered significant
setbacks in advanced clinical trials, even after promising results in earlier
trials. In addition, there can be no assurance that product issues will not
arise following successful clinical trials and FDA approval.
The rate of completion of clinical trials also depends on the rate of
patient enrollment. Patient enrollment depends on many factors, including the
size of the patient population, the nature of the protocol, the proximity of
patients to clinical sites and the eligibility criteria for the study. Delays in
planned patient enrollment may result in increased costs and delays, which could
have a material adverse effect on our business, financial condition and results
of operations.
Government Regulation
Any products tested, manufactured or distributed by us or on our behalf
pursuant to FDA clearances or approvals are subject to pervasive and continuing
regulation by numerous regulatory authorities, including primarily the FDA.
Changes in existing requirements or adoption of new requirements or policies
could adversely affect our ability to comply with regulatory requirements. If we
fail to comply with regulatory requirements, there could be a material adverse
effect on our business, financial condition and results of operations. There can
be no assurance that we will not be required to incur significant costs to
comply with laws and regulations in the future or that laws or regulations will
not have a material adverse effect upon our business, financial condition and
results of operations.
Numerous federal, state and local governmental authorities (each a
"Regulatory Agency"), principally the FDA, and similar agencies in other
countries, regulate the preclinical testing, clinical trials, manufacture and
promotion of any compounds we or our collaborative partners develop and the
manufacturing and marketing of any resulting drugs. The drug development and
regulatory approval process is lengthy, expensive, uncertain and subject to
delays.
- Any compound we or our collaborative partners develop must
receive Regulatory Agency approval before it may be
marketed as a drug in a particular country.
- The regulatory process, which includes preclinical testing
and clinical trials of each compound in order to establish
its safety and efficacy, varies from country to country,
can take many years and requires the expenditure of
substantial resources.
- In all circumstances, approval of the use of previously
unapproved radioisotopes in certain of our products
requires approval of either the Nuclear Regulatory
Commission or equivalent state regulatory agencies. A
radioisotope is an unstable form of an element which
undergoes radioactive decay, thereby emitting radiation
which may be used, for example, to image or destroy
harmful growths or tissue. There can be no assurance that
such approvals will be obtained on a timely basis, or at
all.
- Data obtained from preclinical and clinical activities are
susceptible to varying interpretations which could delay,
limit or prevent Regulatory Agency approval.
15
<PAGE>
- Delays or rejections may be encountered based upon changes
in Regulatory Agency policy during the period of drug
development and/or the period of review of any application
for Regulatory Agency approval for a compound. These
delays could adversely affect the marketing of any
products we or our collaborative partners develop, impose
costly procedures upon our activities, diminish any
competitive advantages we or collaborative partners may
attain and adversely affect our ability to receive
royalties.
There can be no assurance that, even after such time and expenditures,
Regulatory Agency approvals will be obtained for any compounds developed by or
in collaboration with the Company. Moreover, if Regulatory Agency approval for a
drug is granted, such approval may entail limitations on the indicated uses for
which it may be marketed that could limit the potential market for any such
drug. Furthermore, if and when such approval is obtained, the marketing,
manufacture, labeling, storage and record keeping related to our products would
remain subject to extensive regulatory requirements. Discovery of previously
unknown problems with a drug, its manufacture, or its manufacturer may result in
restrictions on such drug, manufacture or manufacturer, including withdrawal of
the drug from the market. Failure to comply with regulatory requirements could
result in fines, suspension of regulatory approvals, operating restrictions and
criminal prosecution.
The U. S. Food, Drug and Cosmetics Act requires that our products be
manufactured in FDA registered facilities subject to inspection. The
manufacturer must be in compliance with current good manufacturing practices,
or, cGMP, which imposes certain procedural and documentation requirements upon
us, and our manufacturing partners with respect to manufacturing and quality
assurance activities. Noncompliance with cGMP can result in, among other things,
fines, injunctions, civil penalties, recalls or seizures of products, total or
partial suspension of production, failure of the government to grant premarket
clearance or premarket approval for drugs, withdrawal of marketing approvals and
criminal prosecution. If we or our manufacturing partners were to fail to comply
with the requirements of cGMP, there could be a material adverse effect on the
Company's business, financial condition and results of operations.
Attraction and Retention of Key Personnel
We are highly dependent on the principal members of our management and
scientific staff, the loss of whose services might significantly delay or
prevent the achievement of research, development or strategic objectives. Our
success depends on our ability to retain key employees and to attract additional
qualified employees. Competition for such personnel is intense, and there can be
no assurance that we will be able to retain existing personnel and to attract,
assimilate or retain additional highly qualified employees in the future.
We have an employment agreement with our President and Chief Executive
Officer, H. Joseph Reiser, Ph.D., which provides for bonuses and vesting of
options for the purchase of shares of common stock based on continued employment
and on the achievement of performance objectives defined by the Board of
Directors. We do not have employment agreements with our other key personnel. If
we are unable to hire and retain personnel in key positions, there could be a
material adverse effect on the Company's business, financial condition and
results of operations.
Potential Inadequacy of Product Liability Insurance
Our business is subject to product liability risks inherent in the testing,
manufacturing and marketing of our products. There can be no assurance that
product liability claims will not be asserted against us, our collaborators or
licensees. While we currently maintain product liability insurance in amounts we
16
<PAGE>
believe are adequate, there can be no assurance that such coverage will be
adequate to protect us against future product liability claims or that product
liability insurance will be available to us in the future on commercially
reasonable terms, if at all. Furthermore, there can be no assurance that we will
be able to avoid significant product liability claims and adverse publicity.
Consequently, a product liability claim or other claim with respect to uninsured
or underinsured liabilities could have a material adverse effect on our
business, financial condition and results of operations.
Environmental Regulation
We are subject to a variety of local, state and federal government
regulations relating to:
- Storage;
- Discharge;
- Handling;
- Emission;
- Generation;
- Manufacture; and
- Disposal
of toxic, infectious or other hazardous substances used to manufacture our
products. If we fail to comply with these regulations, we could be subject to
significant liabilities, which could have a material adverse effect on our
business, financial condition and results of operations.
Volatility of Stock Price
The market prices for securities of biotechnology and pharmaceutical
companies have historically been highly volatile, and the market has from time
to time experienced significant price and volume fluctuations that are unrelated
to the operating performance of particular companies. The market price of our
common stock has fluctuated over a wide range and may continue to fluctuate for
various reasons, including, but not limited to, announcements concerning the
Company or our competitors regarding:
- Results of clinical trials;
- Technological innovations or new commercial products;
- Changes in governmental regulation or the status of our regulatory
approvals or applications;
- Changes in earnings;
- Changes in health care policies and practices;
- Developments or disputes concerning proprietary rights;
- Litigation or public concern as to safety of the our potential
products; and
- Changes in general market conditions.

Impact of Anti-takeover Provisions on the Market Price of Common Stock
We have adopted various anti-takeover provisions which may affect the
market price of the common stock.
Our Board of Directors has the authority, without further action by the
holders of common stock, to issue from time to time, up to 5,200,000 additional
shares of preferred stock in one or more classes or series, and to fix the
rights and preferences of such preferred stock. Pursuant to these provisions, we
have implemented a Stockholder Rights Plan by which one preferred stock purchase
right is attached to each share of common stock, as a means to deter coercive
takeover tactics and to prevent an acquirer from gaining control of the Company
without some mechanism to secure a fair price for all of our stockholders if an
acquisition was completed. These rights will be exercisable if a person or group
acquires beneficial ownership of 20% or more of our common stock and can be made
exercisable by action of our Board of Directors if a person or group commences a
tender offer which would result in such person or group beneficially owning 20%
or more of our common stock. Each right will entitle the holder to buy one
one-thousandth of a share of a new series of junior participating preferred
stock for $20. If any person or group becomes the beneficial owner of 20% or
more of CYTOGEN 's common stock (with certain limited exceptions), then each
right not owned by the 20% stockholder will entitle its holder to purchase, at
the right's then current exercise price, common shares having a market value of
twice the exercise price. In addition, if after any person has become a 20%
stockholder, we are involved in a merger or other business combination
transaction with another person, each right will entitle its holder (other than
the 20% stockholder) to purchase, at the right's then current exercise price,
common shares of the acquiring company having a value of twice the right's then
current exercise price.
We are subject to provisions of Delaware corporate law which, subject to
certain exceptions, will prohibit us from engaging in any "business combination"
with a person who, together with affiliates and associates, owns 15% or more of
our common stock (an "Interested Stockholder") for a period of three years
following the date that such person became an Interested Stockholder, unless the
business combination is approved in a prescribed manner.
These provisions of the Stockholder Rights Plan, our Certificate of
Incorporation, and of Delaware law may have the effect of delaying, deterring or
preventing a change in control of the Company, may discourage bids for the
common stock at a premium over market price and may adversely affect the market
price, and the voting and other rights of the holders, of the common stock.
Impact of Shares Eligible for Future Sale on the Market Price of the Common
Stock
A large number of shares of common stock already outstanding, or issuable
upon exercise of options and warrants, are eligible for resale, which may
adversely affect the market price of the common stock. As of March 31, 1999, the
Company had 65,112,000 shares of common stock outstanding. An additional
7,446,099 shares of common stock are issuable upon the exercise of outstanding
options and warrants (including 300,000 shares issuable upon exercise of
warrants granted to Kingsbridge and the May Davis Group, Inc., placement agent
for the Equity Line Agreement. Substantially all of such shares subject to
outstanding options and warrants will, when issued upon exercise thereof, be
available for immediate resale in the public market pursuant to currently
effective registration statements under the Securities Act of 1933, as amended,
or pursuant to Rule 701 promulgated thereunder.

DIVIDEND POLICY
We have never paid or declared any cash dividends on our common stock. We
currently intend to retain any future earnings for our business and, therefore,
do not anticipate paying cash dividends in the foreseeable future. Future
dividends, if any, will depend on, among other things, our results of
operations, capital requirements, restrictions in loan agreements and on such
other factors as our Board of Directors, in its discretion, may consider
relevant.
USE OF PROCEEDS
We intend to use substantially all of the proceeds from the sale of common
stock hereunder for general corporate purposes.
