THE COMPANY
We are a biopharmaceutical company focusing on the development and commercialization of
innovative therapeutic products to treat the unmet medical needs of patients with debilitating
conditions and life-threatening diseases. Our principal programs are directed toward symptom
management and supportive care and the treatment of Human Immunodeficiency Virus (HIV) infection
and cancer. We do not have any FDA approved products and have not received any revenue from the
sale of any of our product candidates under development. The mailing address of our principal
executive offices is 777 Old Saw Mill River Road, Tarrytown, New York 10591, and our telephone
number is (914) 789-2800. References to Progenics, the Company, we, our and us refers to
Progenics Pharmaceuticals, Inc. and its subsidiary.
RISK FACTORS
Our business and operations entail a variety of risks and uncertainties, including those
described below.
Our product development programs are inherently risky.
We are subject to the risks of failure inherent in the development of product candidates
based on new technologies. Our MNTX product candidate, which is designed to reverse certain side
effects induced by opioids and to treat post-operative bowel dysfunction and is being developed
through a collaboration with Wyeth, is based on a novel method of action that has not yet been
proven to be safe or effective. No drug with MNTXs method of action has ever received marketing
approval. Additionally, some of our HIV product candidates are designed to be effective by blocking
viral entry, and our GMK product candidate is designed to be a therapeutic cancer vaccine. To our
knowledge, no drug designed to treat HIV infection by blocking viral entry (with one exception) and
no cancer therapeutic vaccine has been approved for marketing in the U.S. Our other research and
development programs, and those conducted through our joint venture with Cytogen, involve similarly
novel approaches to human therapeutics. Consequently, there is little precedent for the successful
commercialization of products based on our technologies. There are a number of technological
challenges that we must overcome to complete most of our development efforts. We may not be able to
develop successfully any of our products.
1
We have granted to Wyeth the exclusive rights to develop and commercialize MNTX, our lead
product candidate, and our resulting dependence on Wyeth exposes us to significant risks.
In December 2005, we entered into a license and co-development agreement with Wyeth.
Under this agreement, we granted to Wyeth the exclusive worldwide right to develop and
commercialize MNTX, our lead product candidate. As a result, we are dependent on Wyeth to perform
and fund clinical testing, to make certain regulatory filings and to manufacture and market
products containing MNTX. Our collaboration with Wyeth may not be scientifically, clinically or
commercially successful.
Any revenues from the sale of MNTX, if approved for sale by the FDA, will depend almost
entirely on the efforts of Wyeth. Wyeth has significant discretion in determining the efforts and
resources it applies to sales of our products and may not be effective in marketing our products.
In addition, Wyeth is a large, diversified pharmaceutical company with global operations and its
own corporate agenda, which may not be consistent with our best interests. For example, Wyeth may
change its strategic focus or pursue alternative technologies in a manner that results in reduced
revenues to us. In addition, we will receive milestone payments from Wyeth only if MNTX achieves
specified clinical, regulatory and commercialization milestones, and we will receive royalty
payments from Wyeth only if MNTX receives regulatory approval and is commercialized by Wyeth. Many
of these milestone events will depend on the efforts of Wyeth. We may not receive any milestone or
royalty payments from Wyeth.
Wyeth may terminate the license and co-development agreement:
|
|
|
for any or no reason at any time after two years from the
first commercial sale of the first commercial product
utilizing MNTX in the United States by providing us with at
least 360 days prior written notice and complying with
certain other conditions; |
|
|
|
|
for safety or efficacy reasons by providing us with at least 30 days prior written notice; |
|
|
|
|
upon our material breach or non-compliance with our
representations, warranties and other obligations under the
license and co-development agreement if the non-compliance is
not cured; or |
|
|
|
|
upon our bankruptcy or similar insolvency event. |
If our relationship with Wyeth were to terminate, we would have to either enter into a
license and co-development agreement with another party or develop and commercialize MNTX
ourselves. We may not be able to enter into such an agreement with another suitable company on
acceptable terms or at all. To develop and commercialize MNTX on our own, we would have to develop
a sales and marketing organization and a distribution infrastructure, neither of which we currently
have. Developing these resources would be an expensive and lengthy process and would have a
material adverse effect on our revenues and profitability.
Moreover, a termination of our relationship with Wyeth could seriously compromise the
development program for MNTX. For example, we could experience significant delays in the
development of MNTX and would have to assume full funding and other responsibility for further
development and eventual commercialization.
Any of these outcomes would result in delays in our ability to distribute MNTX and would
increase our expenses, which would have a material adverse effect on our business, results of
operations and financial condition.
Our collaboration with Wyeth is multi-faceted and involves a complex sharing of control
over decisions, responsibilities, costs and benefits. There are numerous potential sources of
disagreement between us and Wyeth, including with respect to product development, marketing
strategies, manufacturing and supply issues and rights relating to intellectual property. Wyeth has
significantly greater financial and managerial resources than we do, which it could draw upon in
the event of a dispute. A disagreement between Wyeth and us could lead to lengthy and expensive
litigation or other dispute resolution proceedings as well as to extensive financial and
operational consequences to us, and have a material adverse effect on our business, results of
operations and financial condition.
2
If testing does not yield successful results, our products will not be approved.
We will need to obtain regulatory approval before we can market our product candidates.
To obtain marketing approval from regulatory authorities, we or our collaborators must demonstrate
a products safety and efficacy through extensive preclinical and clinical testing. Numerous
adverse events may arise during, or as a result of, the testing process, including the following:
|
|
|
the results of preclinical studies may be inconclusive, or
they may not be indicative of results that will be obtained
in human clinical trials; |
|
|
|
|
potential products may not have the desired efficacy or may
have undesirable side effects or other characteristics that
preclude marketing approval or limit their commercial use if
approved; |
|
|
|
|
after reviewing test results, we or our collaborators may
abandon projects, which we previously believed to be
promising; and |
|
|
|
|
we, our collaborators or regulators may suspend or terminate
clinical trials if we or they believe that the participating
subjects or patients are being exposed to unacceptable health
risks. |
Clinical testing is very expensive and can take many years. Results attained in early
human clinical trials may not be indicative of results that are obtained in later clinical trials.
In addition, many of our products, such as PRO 140 and the PSMA product candidates, are at an early
stage of development. The successful commercialization of early stage products will require
significant further research, development, testing, approvals by regulators and additional
investment. Our products in the research or preclinical development stage may not yield results
that would permit or justify clinical testing. Our failure to adequately demonstrate the safety and
efficacy of a product under development would delay or prevent marketing approval of the product,
which could adversely affect our operating results and credibility.
A setback in our clinical development programs could adversely affect us.
We have several ongoing late-stage clinical trials. We have completed enrollment and
patient treatment in our two pivotal phase 3 clinical trials and in the extension study for one of
those trials of sub-cutaneous MNTX for the treatment of opioid-induced constipation in patients
with advanced medical illness. Patient enrollment in the extension study of the second pivotal
trial has been completed and patient treatment is currently ongoing. We will need to successfully
complete and analyze the data from both of these trials, and their extension studies, in order to
obtain approval of the FDA to market MNTX. We also have completed a phase 2 clinical trial of
intravenous MNTX in patients at risk for post-operative bowel dysfunction and intend, working with
our collaborator Wyeth, to conduct additional clinical trials of oral MNTX in chronic pain patients
who experience opioid-induced constipation.
If the results of any of these ongoing trials are not satisfactory, or if we encounter
problems enrolling patients, or if clinical trial supply issues or other difficulties arise, our
entire MNTX development program could be adversely affected, resulting in delays in commencing or
completing clinical trials or in making our regulatory filing for marketing approval. The need to
conduct additional clinical trials or significant revisions to our clinical development plan would
lead to delays in filing for the regulatory approvals necessary to market MNTX. If the clinical
trials indicate a serious problem with the safety or efficacy of a MNTX product then Wyeth has the
right under our license and co-development agreement to terminate the agreement or to stop the
development or commercialization of the affected products. Since MNTX is our most clinically
advanced product, any setback of these types would have a material adverse effect on our stock
price and business.
We also have two ongoing pivotal phase 3 clinical trials for GMK. In May 2000, our
collaborating research cooperative group in one of these trials, ECOG, recommended to clinical
investigators participating in the trial that they discontinue administering GMK, and as a result
that trial did not complete patient dosing as contemplated by the initial trial protocol. A second pivotal phase 3 trial for GMK was initiated in May 2001
and full enrollment of
3
the 1,300 patients called for in the trial has been completed. We expect to
assess the recurrence of cancer and overall survival of the study patients over the next several
years. If the results of either of the GMK trials are not satisfactory, we may need to conduct
additional clinical trials or abandon our GMK program.
We have announced positive phase 1 clinical findings related to PRO 140, and we have
initiated an additional phase 1b clinical trial. We have also decided to ramp down our development
efforts on PRO 542, our other HIV product candidate, in order to concentrate our resources on PRO
140. If the results of our phase 1b study with PRO 140 or the preclinical and clinical studies
involving the PSMA vaccine and antibody candidates are not satisfactory, we would need to
reconfigure our clinical trial programs to conduct additional trials or abandon the program
involved.
We have a history of operating losses, and we may never be profitable.
We have incurred substantial losses since our inception. As of September 30, 2005, we had
an accumulated deficit of approximately $156.0 million. We have derived no significant revenues
from product sales or royalties. We do not expect to achieve significant product sales or royalty
revenue for a number of years, if ever, other than potential revenues from MNTX. We expect to incur
additional operating losses in the future, which could increase significantly as we expand our
clinical trial programs and other product development efforts.
Our ability to achieve and sustain profitability is dependent in part on obtaining
regulatory approval to market our products and then commercializing, either alone or with others,
our products. We may not be able to develop and commercialize products. Moreover, our operations
may not be profitable even if any of our products under development are commercialized.
We are likely to need additional financing, but our access to capital funding is uncertain.
As of September 30, 2005, we had cash, cash equivalents and marketable securities,
including non-current portion, totaling $128.0 million. In December 2005, we received a $60 million
upfront payment from Wyeth in connection with the signing of the license and co-development
agreement relating to MNTX. During the three months and nine months ended September 30, 2005, we
had a net loss of $10.7 million and $36.7 million, respectively, and we used cash in operating
activities of $33.4 million during the nine months ended September 30, 2005.
Under our agreement with Wyeth, Wyeth is responsible for all future development and
commercialization costs relating to MNTX starting January 1, 2006. As a result we expect that our
spending on MNTX in 2006 and beyond will drop significantly from the amounts expended in 2005.
With regard to our other product candidates, however, we expect that we will continue to
incur significant expenditures for their development and we do not have committed external sources
of funding for most of these projects. These expenditures will be funded from our cash on hand, or
we may seek additional external funding for these expenditures, most likely through collaborative
agreements, or other license or sale transactions, with one or more pharmaceutical companies,
through the issuance and sale of securities or through additional government grants or contracts.
We cannot predict with any certainty when we will need additional funds or how much we will need or
if additional funds will be available to us. Our need for future funding will depend on numerous
factors, many of which are outside our control.
Our access to capital funding is uncertain. We may not be able to obtain additional
funding on acceptable terms, or at all. Our inability to raise additional capital on terms
reasonably acceptable to us would seriously jeopardize the future success of our business.
If we raise funds by issuing and selling securities, it may be on terms that are not
favorable to our existing stockholders. If we raise additional funds by selling equity securities,
our current stockholders will be diluted, and new investors could have rights superior to our existing stockholders. If we raise funds by
selling debt securities, we could be subject to restrictive covenants and significant repayment
obligations.
4
Our clinical trials could take longer than we expect.
Although for planning purposes we forecast the commencement and completion of clinical
trials, and have included or incorporated by reference many of those forecasts in this prospectus
and in other public disclosures, the actual timing of these events can vary dramatically. For
example, we have experienced delays in our MNTX clinical development program in the past as a
result of slower than anticipated patient enrollment. These delays may recur. Delays can be caused
by, among other things:
|
|
|
deaths or other adverse medical events involving patients or subjects in our clinical trials; |
|
|
|
|
regulatory or patent issues; |
|
|
|
|
interim or final results of ongoing clinical trials; |
|
|
|
|
failure to enroll clinical sites as expected; |
|
|
|
|
scheduling conflicts with participating clinicians and clinical institutions; and |
|
|
|
|
manufacturing problems. |
In addition, we may need to delay or suspend our clinical trials if we are unable to
obtain additional funding when needed. Also, our clinical programs involving our joint venture with
Cytogen Corporation (Cytogen) could be delayed by disagreements between Cytogen and us concerning
funding development programs or other matters. For example, until June 2005, the joint venture had
no approved 2005 budget or work plan because we and Cytogen had not yet reached agreement with
respect to a number of matters relating to the joint venture. In June 2005, we and Cytogen approved
a work plan and budget for 2005. We have not yet agreed with Cytogen on a work plan and budget for
2006. Clinical trials involving our product candidates may not commence or be completed as
forecasted.
Moreover, we have limited experience in conducting clinical trials, and we rely on others
to conduct, supervise or monitor some or all aspects of some of our clinical trials. In addition,
certain clinical trials for our products may be conducted by government-sponsored agencies, and
consequently will be dependent on governmental participation and funding. Under our agreement with
Wyeth relating to MNTX Wyeth has the responsibility to conduct some of the clinical trials for that
product candidate, including all trials outside of the United States. We will have less control
over the timing and other aspects of these clinical trials than if we conducted them entirely on
our own.
As a result of these and other factors, our clinical trials may not commence or be
completed as we expect or may not be conducted successfully, in which event investors confidence
in our ability to develop products may be impaired and our stock price may decline.
We are subject to extensive regulation, which can be costly and time consuming and can subject
us to unanticipated fines and delays.
We and our products are subject to comprehensive regulation by the FDA in the U.S. and by
comparable authorities in other countries. These national agencies and other federal, state and
local entities regulate, among other things, the preclinical and clinical testing, safety,
approval, manufacture, labeling, marketing, export, storage, record keeping, advertising and
promotion of pharmaceutical products. If we violate regulatory requirements at any stage, whether
before or after marketing approval is obtained, we may be subject to forced removal of a product
from the market, product seizure, civil and criminal penalties and other adverse consequences.
5
Our products do not yet have, and may never obtain, the regulatory approvals needed for
marketing.
None of our products has been approved by applicable regulatory authorities for
marketing. The process of obtaining FDA and foreign regulatory approvals often takes many years and
can vary substantially based upon the type, complexity and novelty of the products involved. We
have had only limited experience in filing and pursuing applications and other submissions
necessary to gain marketing approvals. Our products under development may never obtain the
marketing approval from the FDA or any other regulatory authority necessary for commercialization.
Even if our products receive regulatory approval:
|
|
|
they might not obtain labeling claims necessary to make the
product commercially viable (in general, labeling claims
define the medical conditions for which a drug product may be
marketed, and are therefore very important to the commercial
success of a product); |
|
|
|
|
we or our collaborators might be required to undertake
post-marketing trials to verify the products efficacy or
safety; |
|
|
|
|
we, our collaborators or others might identify side effects
after the product is on the market, or we or our
collaborators might experience manufacturing problems, either
of which could result in subsequent withdrawal of marketing
approval, reformulation of the product, additional
preclinical testing or clinical trials, changes in labeling
of the product or the need for additional marketing
applications; and |
|
|
|
|
we and our collaborators will be subject to ongoing FDA obligations and continuous regulatory review. |
If our products fail to receive marketing approval or lose previously received approvals,
our financial results would be adversely affected.
Even if our products obtain marketing approval, they might not be accepted in the marketplace.
The commercial success of our products will depend upon their acceptance by the medical
community and third party payors as clinically useful, cost effective and safe. If healthcare
providers believe that patients can be managed adequately with alternative, currently available
therapies, they may not prescribe our products, especially if the alternative therapies are viewed
as more effective, as having a better safety or tolerability profile, as being more convenient to
the patient or healthcare providers or as being less expensive. For pharmaceuticals administered in
an institutional setting, the ability of the institution to be adequately reimbursed could also
play a significant role in demand for our products. Even if our products obtain marketing approval,
they may not achieve market acceptance. If any of our products do not achieve market acceptance, we
will likely lose our entire investment in that product.
Marketplace acceptance will depend in part on competition in our industry, which is intense.
The extent to which any of our products achieves market acceptance will depend on
competitive factors. Competition in our industry is intense, and it is accentuated by the rapid
pace of technological development. There are products currently in the market that will compete
with the products that we are developing, including chemotherapy drugs for treating cancer and AIDS
drugs. As described below, Adolor Corporation is developing a drug that would compete with MNTX.
Many of our competitors have substantially greater research and development capabilities and
experience and greater manufacturing, marketing, financial and managerial resources than we do.
These competitors may develop products that are superior to those we are developing and render our
products or technologies non-competitive or obsolete. If our product candidates receive marketing
approval but cannot compete effectively in the marketplace, our operating results and financial
position would suffer.
6
One or more competitors developing an opioid antagonist may reach the market ahead of us and
adversely affect the market potential for MNTX.
We are aware that Adolor Corporation, in collaboration with Glaxo Group Limited, or
Glaxo, a subsidiary of GlaxoSmithKline plc, is developing an opioid antagonist, Entereg
(alvimopan), for post-operative ileus, which has completed phase 3 clinical trials, and for opioid
bowel dysfunction and chronic constipation, which have completed phase 2 trials. Post-operative
ileus is a condition similar to post-operative bowel dysfunction, a condition for which we are
developing MNTX. Entereg is further along in the clinical development process than MNTX, and Adolor
Corporation has received an approvable letter from the U.S. Food and Drug Administration for
Entereg regarding the treatment of post-operative ileus. Additionally, it has been reported that a
European specialty pharmaceutical company is in clinical development of an oral formulation of
methylnaltrexone for use in opioid-induced constipation. If either of these products reaches the
market before MNTX, it could achieve a significant competitive advantage relative to our product.
In any event, the considerable marketing and sales capabilities of Glaxo may impair our ability to
penetrate the market.
Under the terms of our collaboration with Wyeth with respect to MNTX, Wyeth will develop the
oral form of MNTX worldwide. We will lead the U.S. development of the subcutaneous and intravenous
forms of MNTX, while Wyeth will lead development of these parenteral products outside the U.S.
Wyeth and we will pursue an integrated strategy to optimize worldwide development, regulatory
approval, and commercial launch of the three MNTX products, which may impact timelines for the
development of MNTX previously disclosed by us. Decisions regarding the timelines for development
of the three MNTX products will be made by a Joint Development Committee formed under the terms of
the license and co-development agreement, consisting of members from both Wyeth and Progenics.
Disputes with Cytogen could delay or halt our PSMA programs.
Our research and development programs relating to vaccine and antibody immunotherapeutics
based on PSMA are conducted through a joint venture between Cytogen Corporation and us. The JV is a
50/50 joint venture, meaning that our ownership rights in the programs, funding obligations and
governance rights are equal. As a result, for the joint venture to operate efficiently, and for the
research and development programs to be adequately funded and staffed and productive, we and
Cytogen must be in agreement on strategic and operational matters. There is a significant risk
that, as a result of differing views and priorities, there will be occasions when we do not agree
on various matters.
Cytogens and our level of commitment to fund the PSMA joint venture is based upon annual
budgets and work plans that are developed and approved by the parties. We have in the past
experienced delays in reaching agreement with Cytogen regarding annual budget issues and strategic
and operational matters relating to the joint venture. For example, until June 2005, the joint
venture had no approved 2005 budget or work plan because we and Cytogen had not yet reached
agreement with respect to a number of matters relating to the joint venture. In June 2005, we and
Cytogen reached agreement on a work plan and budget for 2005. We have not yet agreed with Cytogen
on a work plan and budget for 2006. If we do not reach an agreement regarding the budget and work
plan for 2006 and future years, we would likely experience delays in advancing the PSMA programs
and may need to dissolve the joint venture and abandon the PSMA programs being conducted by the
joint venture. We may not reach an agreement with Cytogen on these matters.
If we are unable to negotiate collaborative agreements, our cash burn rate could increase and
our rate of product development could decrease.
Our business strategy includes as an element entering into collaborations with
pharmaceutical and biotechnology companies to develop and commercialize our products and
technologies. We recently entered into such a collaboration with Wyeth. However, we may not be
successful in negotiating additional collaborative arrangements. If we do not enter into new
collaborative arrangements, we would have to devote more of our resources to clinical product
development and product-launch activities, and our cash burn rate would increase or we would need
to take steps to reduce our rate of product development.
7
If we do not remedy our failure to achieve milestones or satisfy conditions regarding some of
our product candidates, we may not maintain our rights under our licenses relating to these product
candidates.
We are required to make substantial cash payments, achieve specified milestones and
satisfy other conditions, including filing for and obtaining marketing approvals and introducing
products, to maintain rights under our intellectual property licenses. We may not be able to
maintain our rights under these licenses.
Under our license agreements with Sloan Kettering Institute for Cancer Research relating
to GMK and with Columbia University relating to PRO 542, we are required, among other things, to
have filed for marketing approval for a drug by 2000 and to have commenced commercialization of the
drug by 2002 (for GMK) and to have filed for marketing approval by 2001 (for PRO 542). We have not
achieved these and other milestones and are unlikely to achieve them soon. We are in a similar
position with respect to our license agreement with Antigenics Inc. concerning QS-21, a component
of GMK. If we can establish that our failure to achieve these milestones resulted from technical
issues beyond our control or delays in clinical studies that could not have been reasonably
avoided, we may be entitled to a revision of these milestone dates. Although we believe that we
satisfy one or more of these conditions, we may become involved in disputes with our licensors as
to our continued right to a license. In addition, at September 1, 2004 we became obligated under
our license agreement with Columbia to pay Columbia $225,000. We have accrued this amount but,
pending the outcome of discussions with Columbia regarding this payment and other matters relating
to the license, we have not yet paid it.
If we do not comply with our obligations under our license agreements, the licensors may
terminate them. Termination of any of our licenses could result in our losing our rights to, and
therefore being unable to commercialize, any related product. We have had discussions with
Sloan-Kettering and Columbia to reach agreement on the revision of applicable milestone dates. We
may not, however, reach agreement with these licensors in a manner favorable to us.
We have limited manufacturing capabilities, which could adversely impact our ability to
commercialize products.
We have limited manufacturing capabilities, which may result in increased costs of
production or delay product development or commercialization. In order to commercialize our product
candidates successfully, we or our collaborators must be able to manufacture products in commercial
quantities, in compliance with regulatory requirements, at acceptable costs and in a timely manner.
The manufacture of our product candidates can be complex, difficult to accomplish even in small
quantities, difficult to scale-up for large-scale production and subject to delays, inefficiencies
and low yields of quality products. The cost of manufacturing some of our products may make them
prohibitively expensive. If adequate supplies of any of our product candidates or related materials
are not available to us on a timely basis or at all, our clinical trials could be seriously
delayed, since these materials are time-consuming to manufacture and cannot be readily obtained
from third-party sources.
We operate pilot-scale manufacturing facilities for the production of vaccines and
recombinant proteins. We believe that, for these types of product candidates, these facilities will
be sufficient to meet our initial needs for clinical trials. However, these facilities may be
insufficient for late-stage clinical trials for these types of product candidates, and would be
insufficient for commercial-scale manufacturing requirements. We may be required to expand further
our manufacturing staff and facilities, obtain new facilities or contract with corporate
collaborators or other third parties to assist with production.
In the event that we decide to establish a commercial-scale manufacturing facility, we
will require substantial additional funds and will be required to hire and train significant
numbers of employees and comply with applicable regulations, which are extensive. We may not be
able to build a manufacturing facility that both meets regulatory requirements and is sufficient
for our clinical trials or commercial-scale manufacturing.
We have entered into arrangements with third parties for the manufacture of some of our
products. Our third-party sourcing strategy may not result in a cost-effective means for
manufacturing products. In employing third-
8
party manufacturers, we will not control many aspects of the manufacturing process, including
compliance by these third parties with the FDAs current Good Manufacturing Practices and other
regulatory requirements. We may not be able to obtain adequate supplies from third-party
manufacturers in a timely fashion for development or commercialization purposes, and commercial
quantities of products may not be available from contract manufacturers at acceptable costs.
We are dependent on our patents and other intellectual property rights. The validity,
enforceability and commercial value of these rights are highly uncertain.
Our success is dependent in part on obtaining, maintaining and enforcing patent and other
intellectual property rights. The patent position of biotechnology and pharmaceutical firms is
highly uncertain and involves many complex legal and technical issues. There is no clear policy
involving the breadth of claims allowed, or the degree of protection afforded, under patents in
this area. Accordingly, the patent applications owned by or licensed to us may not result in
patents being issued. We are aware of other groups that have patent applications or patents
containing claims similar to or overlapping those in our patents and patent applications. We do not
expect to know for several years the relative strength or scope of our patent position as compared
to these other groups. Furthermore, patents that we own or license may not enable us to preclude
competitors from commercializing drugs, and consequently may not provide us with any meaningful
competitive advantage.
We own or have licenses to several issued patents. However, the issuance of a patent is
not conclusive as to its validity or enforceability. The validity or enforceability of a patent
after its issuance by the patent office can be challenged in litigation. Our patents may be
successfully challenged. Moreover, we may incur substantial costs in litigation to uphold the
validity of patents or to prevent infringement. If the outcome of litigation is adverse to us,
third parties may be able to use our patented invention without payment to us. Moreover, third
parties may avoid our patents through design innovation.
Most of our product candidate, including MNTX, PRO 140, GMK and our PSMA program
products, incorporate to some degree intellectual property licensed from third parties. We can lose
the right to patents and other intellectual property licensed to us if the related license
agreement is terminated due to a breach by us or otherwise. Our ability, and that of our
collaboration partners, to commercialize products incorporating licensed intellectual property
would be impaired if the related license agreements were terminated.
Generally, we have the right to defend and enforce patents licensed by us, either in the
first instance or if the licensor chooses not to do so. In addition, our license agreement with the
University of Chicago regarding MNTX gives us the right to prosecute and maintain the licensed
patents. We bear the cost of engaging in some or all of these activities with respect to our
license agreements with Sloan-Kettering for GMK, Columbia for PRO 542 and the University of Chicago
for MNTX. With most of our other license agreements, the licensor bears the cost of engaging in
all of these activities, although we may share in those costs under specified circumstances.
Historically, our costs of defending patent rights, both our own and those we license, have not
been material.
We also rely on unpatented technology, trade secrets and confidential information. Third
parties may independently develop substantially equivalent information and techniques or otherwise
gain access to our technology or disclose our technology, and we may be unable to effectively
protect our rights in unpatented technology, trade secrets and confidential information. We require
each of our employees, consultants and advisors to execute a confidentiality agreement at the
commencement of an employment or consulting relationship with us. However, these agreements may not
provide effective protection in the event of unauthorized use or disclosure of confidential
information.
If we infringe third-party patent or other intellectual property rights, we may need to alter
or terminate a product development program.
There may be patent or other intellectual property rights belonging to others that
require us to alter our products, pay licensing fees or cease certain activities. If our products
infringe patent or other intellectual property rights of others, the owners of those rights could
bring legal actions against us claiming damages and seeking to enjoin
9
manufacturing and marketing of the affected products. If these legal actions are successful,
in addition to any potential liability for damages, we could be required to obtain a license in
order to continue to manufacture or market the affected products. We may not prevail in any action
brought against us, and any license required under any rights that we infringe may not be available
on acceptable terms or at all. We are aware of intellectual property rights held by third parties
that relate to products or technologies we are developing. For example, we are aware of other
groups investigating methylnaltrexone and other peripheral opioid antagonists, PSMA or related
compounds and CCR5 monoclonal antibodies and of patents held, and patent applications filed, by
these groups in those areas. While the validity of these issued patents, patentability of these
pending patent applications and applicability of any of them to our programs are uncertain, if
asserted against us, any related patent or other intellectual property rights could adversely
affect our ability to commercialize our products.
The research, development and commercialization of a biopharmaceutical often involve
alternative development and optimization routes, which are presented at various stages in the
development process. The preferred routes cannot be predicted at the outset of a research and
development program because they will depend on subsequent discoveries and test results. There are
numerous third-party patents in our field, and we may need to obtain a license to a patent in order
to pursue the preferred development route of one or more of our products. The need to obtain a
license would decrease the ultimate profitability of the applicable product. If we cannot negotiate
a license, we might have to pursue a less desirable development route or terminate the program
altogether.
We are dependent upon third parties for a variety of functions. These arrangements may not
provide us with the benefits we expect.
We rely in part on third parties to perform a variety of functions. We are party to
numerous agreements which place substantial responsibility on clinical research organizations,
consultants and other service providers for the development of our products. We also rely on
medical and academic institutions to perform aspects of our clinical trials of product candidates.
In addition, an element of our research and development strategy is to in-license technology and
product candidates from academic and government institutions in order to minimize investments in
early research. Furthermore, we recently entered into an agreement under which we will depend on
Wyeth for the commercialization and development of MNTX, our lead product candidate. We may not be
able to maintain any of these relationships or establish new ones on beneficial terms. Furthermore,
we may not be able to enter new arrangements without undue delays or expenditures, and these
arrangements may not allow us to compete successfully.
We lack sales and marketing experience, which will make us dependent on third parties for
their expertise in this area.
We have no experience in sales, marketing or distribution. If we receive marketing
approval, we expect to market and sell our products principally through distribution, co-marketing,
co-promotion or licensing arrangements with third parties. We may also consider contracting with a
third party professional pharmaceutical detailing and sales organization to perform the marketing
function for our products. Under our license and co-development agreement with Wyeth, Wyeth is
responsible for commercializing MNTX. To the extent that we enter into distribution, co-marketing,
co-promotion, detailing or licensing arrangements for the marketing and sale of our other products,
any revenues we receive will depend primarily on the efforts of third parties. We will not control
the amount and timing of marketing resources these third parties devote to our products. In
addition, if we market products directly, significant additional expenditures and management
resources would be required to develop an internal sales force. We may not be able to establish a
successful sales force should we choose to do so.
If we lose key management and scientific personnel on whom we depend, our business could
suffer.
We are dependent upon our key management and scientific personnel. In particular, the
loss of Dr. Paul J. Maddon, our Chief Executive Officer and Chief Science Officer, could cause our
management and operations to suffer. We have an employment agreement with Dr. Maddon, the initial
term of which ran through September 30, 2005, subject to an automatic renewal for an additional
period of two years unless either party provides ninety days prior notice of non-renewal. See Item
11. Executive Compensation Employment Agreements in our Annual
10
Report on Form 10-K for the year ended December 31, 2004. Neither we nor Dr. Maddon gave
notice of non-renewal. We are currently in discussions with Dr. Maddon regarding the renewal of his
employment agreement and expect that the agreement will be renewed. Employment agreements do not,
however, assure the continued employment of an employee. We maintain key-man life insurance on Dr.
Maddon in the amount of $2.5 million.
In October 2004, our Board of Directors elected Paul F. Jacobson and Kurt W. Briner as
Co-chairmen of the Board in substitution of Dr. Paul J. Maddon, our Chief Executive Officer, Chief
Science Officer and a director. Dr. Maddons employment agreement contains provisions relating to
the Chairmanship position. In connection with the renewal of Dr. Maddons employment agreement, we
intend to clarify that the change in the Chairman position is not inconsistent with Dr. Maddons
employment agreement.
Competition for qualified employees among companies in the biopharmaceutical industry is
intense. Our future success depends upon our ability to attract, retain and motivate highly skilled
employees. In order to commercialize our products successfully, we may be required to expand
substantially our personnel, particularly in the areas of manufacturing, clinical trials
management, regulatory affairs, business development and marketing. We may not be successful in
hiring or retaining qualified personnel.
If we are unable to obtain sufficient quantities of the raw and bulk materials needed to make
our products, our product development and commercialization could be slowed or stopped.
We currently obtain supplies of critical raw materials used in production of MNTX, GMK
and other of our product candidates from single sources. In particular, we rely on single-source
third-party manufacturers for the supply of both bulk and finished form MNTX. We have a supply
agreement with Mallinckrodt Inc., our current supplier of bulk-form MNTX, which has an initial term
that expires on January 1, 2008. In accordance with our collaboration with Wyeth, we will transfer
to Wyeth, at a mutually agreeable time, the responsibility for manufacturing MNTX for clinical and
commercial use, including our supply agreements with third parties. We do not have long-term
contracts with any of our other suppliers. In addition, commercialization of GMK requires an
adjuvant, QS-21, available only from Antigenics Inc. Our existing arrangements may not result in
the supply of sufficient quantities of our product candidates needed to accomplish our clinical
development programs, and we may not have the right or capability to manufacture sufficient
quantities of these products to meet our needs if our suppliers are unable or unwilling to do so.
Any delay or disruption in the availability of raw materials would slow or stop product development
and commercialization of the relevant product.
A substantial portion of our funding comes from federal government grants and research
contracts. We cannot rely on these grants or contracts as a continuing source of funds.
A substantial portion of our revenues to date has been derived from federal government
grants and research contracts. In September 2005, we were awarded a $10.1 million grant from the
NIH to partially fund our PRO 140 program. Also, in 2004 we were awarded, in the aggregate,
approximately $9.2 million in NIH grants and research contracts in addition to previous years
awards. We cannot rely on grants or additional contracts as a continuing source of funds. Moreover,
funds available under these grants and contracts must be applied by us toward the research and
development programs specified by the government rather than for all our programs generally. For
example, the $28.6 million contract awarded to us by the NIH in September 2003 must be used by us
in furtherance of our efforts to develop an HIV vaccine. The governments obligation to make
payments under these grants and contracts is subject to appropriation by the U.S. Congress for
funding in each year. Moreover, it is possible that Congress or the government agencies that
administer these government research programs will decide to scale back these programs or terminate
them due to their own budgetary constraints. Additionally, these grants and research contracts are
subject to adjustment based upon the results of periodic audits performed on behalf of the granting
authority. Consequently, the government may not award grants or research contracts to us in the
future, and any amounts that we derive from existing grants or contracts may be less than those
received to date.
If health care reform measures are enacted, our operating results and our ability to
commercialize products could be adversely affected.
11
In recent years, there have been numerous proposals to change the health care system in
the U.S. and in foreign jurisdictions. Some of these proposals have included measures that would
limit or eliminate payments for medical procedures and treatments or subject the pricing of
pharmaceuticals to government control. In some foreign countries, particularly countries of the
European Union, the pricing of prescription pharmaceuticals is subject to governmental control. In
addition, as a result of the trend towards managed health care in the U.S., as well as legislative
proposals to reduce government insurance programs, third-party payors are increasingly attempting
to contain health care costs by limiting both coverage and the level of reimbursement of new drug
products. Consequently, significant uncertainty exists as to the reimbursement status of newly
approved health care products.
If we or any of our collaborators succeed in bringing one or more of our products to
market, third-party payors may establish and maintain price levels insufficient for us to realize
an appropriate return on our investment in product development. Significant changes in the health
care system in the U.S. or elsewhere, including changes resulting from adverse trends in
third-party reimbursement programs, could have a material adverse effect on our operating results
and our ability to raise capital and commercialize products.
We are exposed to product liability claims, and in the future we may not be able to obtain
insurance against these claims at a reasonable cost or at all.
Our business exposes us to product liability risks, which are inherent in the testing,
manufacturing, marketing and sale of pharmaceutical products. We may not be able to avoid product
liability exposure. If a product liability claim is successfully brought against us, our financial
position may be adversely affected.
Product liability insurance for the biopharmaceutical industry is generally expensive,
when available at all. We have obtained product liability insurance in the amount of $5.0 million
per occurrence, subject to a deductible and a $5.0 million annual aggregate limitation. In
addition, where local statutory requirements exceed the limits of our existing insurance or where
local policies of insurance are required, we maintain additional clinical trial liability insurance
to meet these requirements. Our present insurance coverage may not be adequate to cover claims
brought against us. In addition, some of our license and other agreements require us to obtain
product liability insurance. Adequate insurance coverage may not be available to us at a reasonable
cost in the future.
We handle hazardous materials and must comply with environmental laws and regulations, which
can be expensive and restrict how we do business. If we are involved in a hazardous waste spill or
other accident, we could be liable for damages, penalties or other forms of censure.
Our research and development work and manufacturing processes involve the use of
hazardous, controlled and radioactive materials. We are subject to federal, state and local laws
and regulations governing the use, manufacture, storage, handling and disposal of these materials.
Despite procedures that we implement for handling and disposing of these materials, we cannot
eliminate the risk of accidental contamination or injury. In the event of a hazardous waste spill
or other accident, we could be liable for damages, penalties or other forms of censure. In
addition, we may be required to incur significant costs to comply with environmental laws and
regulations in the future.
Our stock price has a history of volatility. You should consider an investment in our stock as
risky and invest only if you can withstand a significant loss.
Our stock price has a history of significant volatility. Between January 1, 2002 and
September 30, 2005, our stock price has ranged from $3.82 to $25.07 per share. At times, our stock
price has been volatile even in the absence of significant news or developments relating to us.
Moreover, the stocks of biotechnology companies and the stock market generally have been subject to
dramatic price swings in recent years. Factors that may have a significant impact on the market
price of our common stock include:
|
|
|
the results of clinical trials and preclinical studies involving our products or those of our competitors; |
|
|
|
|
changes in the status of any of our drug development programs, including delays in clinical trials or program terminations; |
12
|
|
|
developments regarding our efforts to achieve marketing approval for our products; |
|
|
|
|
developments in our relationship with Wyeth regarding the
development and commercialization of MNTX; |
|
|
|
|
announcements of technological innovations or new commercial
products by us, our collaborators or our competitors; |
|
|
|
|
developments in our relationships with other collaborative partners; |
|
|
|
|
developments in patent or other proprietary rights; |
|
|
|
|
governmental regulation; |
|
|
|
|
changes in reimbursement policies or health care legislation; |
|
|
|
|
public concern as to the safety and efficacy of products
developed by us, our collaborators or our competitors; |
|
|
|
|
our ability to fund on-going operations; |
|
|
|
|
fluctuations in our operating results; and |
|
|
|
|
general market conditions. |
Our principal stockholders are able to exert significant influence over matters submitted to
stockholders for approval.
At September 30, 2005, Dr. Maddon and stockholders affiliated with Tudor Investment
Corporation together beneficially own or control approximately 19% of our outstanding shares of
common stock. These persons, should they choose to act together, could exert significant influence
in determining the outcome of corporate actions requiring stockholder approval and otherwise
control our business. This control could have the effect of delaying or preventing a change in
control of us and, consequently, could adversely affect the market price of our common stock.
Anti-takeover provisions may make the removal of our Board of Directors or management more
difficult and discourage hostile bids for control of our company that may be beneficial to our
stockholders.
Our Board of Directors is authorized, without further stockholder action, to issue from
time to time shares of preferred stock in one or more designated series or classes. The issuance of
preferred stock, as well as provisions in certain of our stock options that provide for
acceleration of exercisability upon a change of control, and Section 203 and other provisions of
the Delaware General Corporation Law could:
|
|
|
make the takeover of Progenics or the removal of our Board of Directors or management more difficult; |
|
|
|
|
discourage hostile bids for control of Progenics in which
stockholders may receive a premium for their shares of common
stock; and |
|
|
|
|
otherwise dilute the rights of holders of our common stock
and depress the market price of our common stock. |
13
If there are substantial sales of our common stock, the market price of our common stock could
decline.
Sales of substantial numbers of shares of common stock could cause a decline in the
market price of our stock. We require substantial external funding to finance our research and
development programs and may seek such funding through the issuance and sale of our common stock.
Sales of our common stock pursuant to this registration statement could cause the market price or
our stock to decline. In addition, some of our other stockholders are entitled to require us to
register their shares of common stock for offer or sale to the public. Also, we have filed Form S-8
registration statements registering shares issuable pursuant to our equity compensation plans. Any
sales by existing stockholders or holders of options may have an adverse effect on our ability to
raise capital and may adversely affect the market price of our common stock.
14
FORWARD-LOOKING STATEMENTS
Certain statements in this prospectus, any prospectus supplement and the documents we
have filed with the Securities and Exchange Commission that are incorporated by reference into this
prospectus and any prospectus supplement constitute forward-looking statements within the meaning
of the Private Securities Litigation Reform Act of 1995. Included in these forward-looking
statements are statements regarding our expectations for beginning or completing clinical trials,
submitting to regulatory authorities applications for marketing approvals for our product
candidates, raising additional capital and reducing our operating costs if we cannot raise
additional funds. Such forward-looking statements involve known and unknown risks, uncertainties
and other factors which may cause our actual results, performance or achievements, or industry
results, to be materially different from any expected future results, performance or achievements
expressed or implied by such forward-looking statements. These factors include, among others, the
risks associated with our dependence on Wyeth to fund clinical testing, to make certain regulatory
filings and to manufacture and market products containing MNTX, the uncertainties associated with
product development, the risk that clinical trials will not commence, proceed or be completed as
planned, the risk that our products will not receive marketing approval from regulators, the risks
and uncertainties associated with the dependence upon the actions of our corporate, academic and
other collaborators and of government regulatory agencies, the risk that our licenses to
intellectual property may be terminated because of our failure to have satisfied performance
milestones, the risk that products that appear promising in early clinical trials are later found
not to work effectively or are not safe, the risk that we may not be able to manufacture commercial
quantities of our products, the risk that our products, if approved for marketing, do not gain
market acceptance sufficient to justify development and commercialization costs, the risk that we
will not be able to obtain funding necessary to conduct our operations, the uncertainty of future
profitability and other factors set forth more fully in this prospectus, any prospectus supplement
and the documents incorporated by reference herein, including those factors described under the
caption Risk Factors, to which investors are referred for further information.
We do not have a policy of updating or revising forward-looking statements, and we assume
no obligation to update any forward-looking statements contained or incorporated by reference in
this prospectus and any accompanying prospectus supplement as a result of new information or future
events or developments. Thus, you should not assume that our silence over time means that actual
events are bearing out as expressed or implied in such forward-looking statements.
15
USE OF PROCEEDS
We will not receive any proceeds from the sale by the selling stockholders of the shares
of common stock they may offer through this prospectus.
SELLING STOCKHOLDERS
We are registering for resale 186,000 shares of our common stock held by the selling
stockholders named below pursuant to this prospectus and any applicable prospectus supplement. The
shares subject to resale hereunder were issued in connection with our acquisition of contract
rights previously held by Susanne Glink, Mark Goldberg and the Claudia Otee Trust (collectively,
the selling stockholders). This transaction was completed on December 22, 2005. The rights that
we acquired provided for UR Labs, Inc. (UR Labs) to make payments to the selling stockholders in
respect of payments received by UR Labs as a result of its licensing to us intellectual property
relating to MNTX. Our acquisition of these rights effectively extinguished UR Labs payment
obligations to the selling stockholders. As part of this acquisition, we agreed to register for
resale by the selling stockholders the 186,000 shares of our common stock issued to them. We also
agreed to provide indemnification rights to the selling stockholders.
The selling stockholders may sell all, a portion or none of the shares covered by this
prospectus at any time up to December 22, 2007. We are not obligated to maintain in effect after
that date the registration statement of which this prospectus forms a part. The selling
stockholders may also sell, transfer or otherwise dispose of some or all of their shares (including
shares not covered by this prospectus) in transactions exempt from the registration requirements of
the Securities Act of 1933 (the Securities Act). We do not know when or in what amounts the
selling stockholders may offer shares under this prospectus or otherwise. As a result, we cannot
estimate with certainty the number of shares of our common stock that will be owned by each selling
stockholder after the completion of any offering contemplated by this prospectus.

16
PLAN OF DISTRIBUTION
The selling stockholders may sell the shares being offered from time to time in one or
more transactions:
|
|
|
on The Nasdaq National Market; |
|
|
|
|
in the over-the-counter market; |
|
|
|
|
in privately negotiated transactions; |
|
|
|
|
through broker-dealers, who may act as agents or principals; |
|
|
|
|
through one or more underwriters on a firm commitment or best efforts basis; |
|
|
|
|
through the writing of options on shares, whether the options
are listed on an options exchange or otherwise; or |
|
|
|
|
a combination of such methods of sale. |
The shares may be sold at fixed prices that may be changed, at market prices prevailing
at the time of sale, at prices related to such market prices or at negotiated prices. Such
transactions may or may not involve brokers or dealers. Any brokers or dealers participating in a
transaction may receive compensation in the form of discounts, commissions or concessions from the
selling stockholders or the purchasers of shares for whom such brokers or dealers act as agent or
to whom they sell as principal, or both (which compensation as to a particular broker or dealer
might be in excess of customary commissions).
The shares can only be sold through registered or licensed brokers or dealers if required
under applicable state securities laws. In addition, in certain states the shares may not be sold
unless they have been registered or qualified for sale in the applicable state or an exemption from
the registration or qualification requirement is available and is complied with.
The selling stockholders and any brokers, dealers or agents that act in connection with
the sale of shares might be deemed to be underwriters within the meaning of Section 2(11) of the
Securities Act, and any commissions received by any such brokers, dealers or agents, and any
profits realized on the resale of shares sold by them while acting as principals, might be deemed
to be underwriting discounts and commissions under the Securities Act.
The selling stockholders will be subject to the prospectus delivery requirements of the
Securities Act with respect to sales of shares through this prospectus. We intend to inform the
selling stockholders that the anti-manipulation provisions of Regulation M promulgated under the
Securities Exchange Act of 1934 may apply to their sales in the market.
The selling stockholders also may resell all or a portion of their shares in open market
transactions in reliance on Rule 144 under the Securities Act, provided they conform to the
requirements of Rule 144, including a one-year holding period.
We will bear all costs, expenses and fees in connection with the registration of the
shares. The selling stockholders will bear all commissions and discounts, if any, attributable to
the sales of the shares. The selling stockholders may agree to indemnify certain persons, including
broker-dealers and agents, against certain liabilities in connection with the offering of the
shares, including liabilities arising under the Securities Act.
