                               PROSPECTUS SUMMARY

Because this is a summary, it does not contain all the details that may be
important to you. You should read this entire prospectus, including "Risk
Factors," carefully before you invest.

                                 COMPANY SUMMARY

We are a critical care company that focuses on developing compounds to treat
respiratory diseases that affect the ability of the lungs to absorb oxygen. We
are in late stage development with our lead product candidate, Surfaxin(R), and
are initially focusing on developing Surfaxin(R) for use by critical care units
of hospitals as a treatment for two respiratory conditions in newborn infants.
We are also developing Surfaxin(R) for the treatment of acute respiratory
distress syndrome ("ARDS") in adult patients and acute lung injury ("ALI") in
adult patients (ARDS and ALI may be referred to herein collectively as
"ARDS/ALI"). We believe that we can use other formulations of Surfaxin(R) or our
proprietary synthetic peptide, sinapultide, to treat other respiratory
conditions. These include asthma and chronic obstructive pulmonary disease. In
addition, we believe we can use Surfaxin(R) to efficiently deliver drugs through
the respiratory tract that are currently delivered orally or by injection. These
drugs include antibiotics, pulmonary vasodilators, elastase inhibitors,
bronchodilators, steroids and proteins. We are also evaluating the acquisition
of licenses to other drug products for the treatment of respiratory and other
neonatal critical care diseases. We may develop and market our products on our
own or seek to enter into collaborations with corporate partners for the
manufacturing and marketing of these drugs.

Surfaxin(R) is a formulation of a humanized, synthetic lung surfactant
containing a peptide that mimics a human protein. We patterned Surfaxin(R) after
human surfactant protein B. Surfactants are substances that are produced
naturally in the lungs. They possess the ability to lower the surface tension of
the fluid normally present within the air sacs that are inside of the lungs. In
the absence of sufficient surfactants these air sacs tend to collapse. As a
result, the lungs do not absorb sufficient oxygen.

We intend to use Surfaxin(R) for the treatment of several respiratory
conditions. Currently, we are developing Surfaxin(R) for the treatment of
idiopathic respiratory distress syndrome ("IRDS") in premature infants, meconium
aspiration syndrome ("MAS") in full-term infants, and ARDS/ALI. We have also
begun developing Surfaxin(R) to treat other respiratory disorders.

IRDS is a condition in which premature infants are born with an insufficient
amount of their own natural surfactant. MAS is a similar condition, in which
full-term infants are born with meconium in their lungs which depletes the
natural surfactant in their lungs. Meconium is a baby's first bowel movement in
its mother's womb. MAS can occur if the baby breathes in meconium. Both IRDS and
MAS can be life-threatening as a result of the failure of the lungs to absorb
sufficient oxygen. These conditions can also deplete natural surfactants in the
lungs and result in the need for mechanical ventilation. ARDS/ALI can result
from a variety of events. Some of these events are pneumonia, septic shock,
breathing in the contents of the stomach, trauma, smoke inhalation, near
drowning, pancreatitis and head injury.

IRDS affects approximately 60,000 premature infants per year in the United
States with an estimated approximately 120,000 infants receiving surfactant
therapy worldwide. The incidence of ARDS/ALI ranges between approximately
150,000 and 250,000 patients per year in the United States with a fatality rate
as high as 35% to 70%. MAS affects approximately 22,000 to 26,000 newborn
infants per year in the United States with an estimated equal number of newborn
infants afflicted per year in the rest of the developed world.

Presently, the United States Food and Drug Administration ("FDA") has only
approved replacement surfactants for treating IRDS in premature infants. The
most commonly used of these approved replacement surfactants are products
derived from pigs and cows and require relatively complex extractive
manufacturing processes. In contrast, Surfaxin(R), is a humanized, synthetic
surfactant modeled after the most active protein found in human surfactant. We
believe that we can manufacture Surfaxin(R) less expensively than the animal
derived surfactants. In addition we believe that Surfaxin(R) might possess other
pharmaceutical benefits not currently found with the animal-derived surfactants
such as its resistance to proteolytic degradation and the absence of risk of
potential transmission of animal-borne diseases including brain-wasting bovine
spongiform encephalopathy (commonly called "mad-cow disease").

There are presently no drug therapies approved for the treatment of MAS and
ARDS. The FDA has granted Surfaxin(R) fast track designation for the indications
of MAS and ARDS. Fast track status does not accelerate our clinical trials nor
does it mean that the regulatory requirements are less stringent. However, the
FDA will review the New Drug Application (an "NDA") for a drug granted fast
track status within six months. The FDA has awarded us an orphan drug grant to
support our development of Surfaxin(R) in MAS and has designated Surfaxin(R) as
an orphan drug for the treatment of MAS, IRDS and ARDS. We have also recently
received designation of Surfaxin(R) as an orphan product for MAS from the
European Medicines Evaluation Agency ("EMEA"). Additional applications for
orphan product designation for IRDS and ARDS/ALI are currently under review at
the EMEA. In October 2000, we were awarded a $1 million Fast-Track Small
Business Innovative Research ("SBIR") grant by the National Institutes of Health
to develop Surfaxin(R) for ARDS/ALI.

We have begun preclinical research into formulating Surfaxin(R) into an aerosol
spray for the treatment of asthma, chronic obstructive pulmonary disease, acute
and chronic bronchitis and a variety of other respiratory diseases. We are also
initiating preclinical research to evaluate Surfaxin(R) or related formulations
as a novel pulmonary drug delivery technology with the potential to deliver
other pharmaceutical products to the lungs so that such products can exert their
pharmacological effects locally or systemically.

We are presently evaluating if and how our second compound under development,
SuperVent(TM) (active compound, tyloxapol), should be developed. We believe that
SuperVent(TM) could be used to treat airway diseases such as cystic fibrosis and
chronic bronchitis. Cystic Fibrosis is a progressive, lethal respiratory disease
that afflicts approximately 28,000 patients in the United States and a
comparable number in Europe. A new therapy that is intended to minimize the
complications of Cystic Fibrosis could have a major impact on the length and
quality of life of its patients. SuperVent(TM) is delivered to patients using a
nebulizer, a device that turns liquid into mist, making it breathable.

We are presently enrolling patients in a pivotal Phase 3 clinical trial of
Surfaxin(R) for the treatment of MAS in neonates, and have designed pivotal
Phase 3 multinational clinical trials intended to be conducted in North and
South America, as well as Europe, for the treatment of IRDS in premature
infants. Given our belief in the importance of IRDS to our present development
plan, resources have been and may continue to be reallocated from


                                       1


the MAS program to the IRDS program, which, could effectively delay the
completion of the MAS trial. In July 2001, we commenced enrollment for the Phase
3 IRDS program. In addition, we have initiated a Phase 2 clinical trial of
Surfaxin(R) for the treatment of ARDS. We are also evaluating whether to conduct
further clinical trials of SuperVent(TM) for treatment of Cystic Fibrosis.

                                  RISK FACTORS

The following important factors, among others, could cause the Company's actual
results, performance, achievements or industry results to differ materially from
those expressed in the Company's forward-looking statements contained herein and
presented elsewhere by management from time to time.

Because we are a development stage company, we may not successfully develop and
market our products, and even if we do, we may not generate enough revenue or
become profitable.

We are a development stage company. Therefore, you must evaluate us in light of
the uncertainties and complexities present in a development stage biotechnology
company. We are conducting research and development on our product candidates.
As a result, we have not begun to market or generate revenues from the
commercialization of any of these products. We will need to engage in
significant, time-consuming and costly research, development, pre-clinical
studies, clinical testing and regulatory approval for our products under
development prior to their commercialization. In addition, pre-clinical or
clinical studies may show that our products are not effective or safe for one or
more of their intended uses. We may fail in the development and
commercialization of our products. To date, we have generated significant and
increasing operating losses, and we expect to continue to incur significant
increasing operating losses over the next several years. If we succeed in the
development of our products, we still cannot assure you that we will generate
sufficient or sustainable revenues or that we will be profitable.

The types of products we are developing are subject to risks that are difficult
to foresee and we may not succeed in our development efforts.

The development of our products is subject to the risks of failure inherent in
the development of new pharmaceutical products that utilize innovative or new
technologies. During the development process we could experience unforeseen
problems that could delay us from completing the development of one or more of
our products. As a result, we may terminate development of any such products or
applications. We cannot assure you:

--that we will succeed in our research and development; or

--that we will be able to successfully and economically manufacture and market
  our proposed products.

If we cannot raise additional capital we may need to discontinue our research
and development activities. In addition, any additional financing could result
in equity dilution.

We may need substantial additional funding to conduct our research and product
development activities. Based on our current operating plan, we believe that our
currently available resources will be adequate to satisfy our capital needs into
the third quarter of 2002. Our future capital requirements will depend on the
results of our research and development activities, clinical studies and trials,
competitive and technological advances and the regulatory process. If our
operations do not become profitable before we exhaust our resources, we will
likely need to raise substantial additional funds through collaborative ventures
with potential corporate partners and through additional debt or equity
financings. We may in some cases elect to develop products on our own instead of
entering into collaboration arrangements. This would increase our cash
requirements for research and development. We cannot assure you that we will
obtain necessary financing.

Other than in connection with this Offering, we have not entered into
arrangements to obtain any additional financing. Any additional financing could
include unattractive terms or result in significant dilution of stockholders'
interests and share prices may decline. If we fail to enter into collaborative
ventures or to receive additional funding, we may have to delay, scale back or
discontinue our research and development operations, and consider licensing the
development and commercialization of products that we consider valuable and
which we otherwise would have developed ourselves. Furthermore, we could cease
to qualify for listing of our securities on the SmallCap Market. See "Risk
Factors--The market price of our stock may be adversely affected by market
volatility."

The clinical trial and regulatory approval process for the Company's products
will be expensive and time consuming, and the outcome is uncertain.

In order to sell our products that are under development, we must receive
regulatory approvals for each product. The FDA and comparable agencies in
foreign countries extensively and rigorously regulate the testing, manufacture,
distribution, advertising, pricing and marketing of drug products like our
products. This approval process includes preclinical studies and clinical trials
of each pharmaceutical compound to establish its safety and effectiveness and
confirmation by such agencies that the manufacturer maintains good laboratory
and manufacturing practices during testing and manufacturing. The process is
lengthy, expensive and uncertain. It is also possible that the FDA or comparable
foreign regulatory authorities could interrupt, delay or halt our clinical
trials. If we, or such authorities, believe that trial participants face
unacceptable health risks, the trials could be suspended or terminated. We also
may not reach agreement with the FDA and/or comparable foreign agencies on the
design of clinical studies necessary for approval. In addition, conditions
imposed by such agencies on our clinical trials could significantly increase the
time required for completion of our clinical trials and the costs of conducting
such clinical trials.

To succeed, clinical trials require adequate supplies of drug substance and drug
product, which may be difficult or uneconomical to procure or manufacture, and
sufficient patient enrollment. Patient enrollment is a function of several
factors, including the size of the patient population, the nature of the
protocol, the proximity of the patients to the trial sites and the eligibility
criteria for the clinical trials. Delays in patient enrollment can result in
greater costs and longer trial timeframes. Patients may also suffer adverse
medical events or side effects.

Clinical trials generally take two to five years or more to complete, and,
accordingly, our first product is not expected to be commercially available in
the Unites States until at least 2002, and our other product candidates will
take longer. The FDA has notified us that two of our intended indications for
Surfaxin(R), MAS and ARDS, have been granted designation as "fast track"
products under provisions of the Food and Drug Administration Modernization Act
of 1997, and the FDA has awarded us an orphan drug grant to support our
development of Surfaxin(R) in MAS. Fast track status does not accelerate the
clinical trials nor does it mean that the regulatory requirements are less
stringent. The fast track provisions are designed to


                                       3


expedite the FDA's review of new drugs intended to treat serious or
life-threatening conditions. The FDA generally will review the NDA for a drug
granted fast track status within six months instead of the typical one to three
years. Our products may not, however, continue to qualify for expedited review
and our other drug candidates may fail to qualify for fast track development or
expedited review. Even though some of our drug candidates have qualified for
expedited review, the FDA may not approve them at all or any sooner than other
drug candidates that do not qualify for expedited review.

The FDA and comparable foreign agencies could withdraw any approvals we obtain.
Further, if there is a later discovery of unknown problems or if we fail to
comply with other applicable regulatory requirements at any stage in the
regulatory process, the FDA may restrict or delay our marketing of a product or
force us to make product recalls. In addition, the FDA could impose other
sanctions such as fines, injunctions, civil penalties or criminal prosecutions.
To market our products outside the United States, we also need to comply with
foreign regulatory requirements governing human clinical trials and marketing
approval for pharmaceutical products. The FDA and foreign regulators have not
yet approved any of our products under development for marketing in the United
States or elsewhere. If the FDA and other regulators do not approve our
products, we will not be able to market our products.

Our strategy, in many cases, is to enter into collaboration agreements with
third parties with respect to our products and we may require additional
collaboration agreements. If we enter into these agreements and the third
parties do not perform, it could impair our ability to commercialize our
products.

Our strategy for the completion of the required development and clinical testing
of our products and for the manufacturing, marketing and commercialization of
our products, in many cases, depends upon entering into collaboration
arrangements with pharmaceutical companies. We have entered into a sublicense
agreement for Surfaxin(R) covering southern Europe and Latin America with an
option for Italy. We may need to enter into additional collaboration agreements.
Our success may depend upon obtaining collaboration partners. In addition, we
may depend on our partners' expertise and dedication of sufficient resources to
develop and commercialize our proposed products. We may, in the future, grant to
collaboration partners rights to license and commercialize pharmaceutical
products developed under collaboration agreements. Under these arrangements our
collaboration partners may control key decisions relating to the development of
the products. Such rights would limit our flexibility in considering
alternatives for the commercialization of our products. If we fail to
successfully develop these relationships or if our collaboration partners fail
to successfully develop or commercialize any of our products, it may delay or
prevent us from developing or commercializing our products in a competitive and
timely manner.

Discoveries or developments of new technologies by our competitors or others may
make our products less competitive or make our products obsolete.

There are rapidly changing technologies and evolving industry standards in the
biotechnology and pharmaceutical markets. We intend to market our products under
development for the treatment of diseases for which other technologies and
proposed treatments are rapidly developing. Third parties conducting research
include governments, major research facilities and large multinational
corporations. Many of the third parties have greater research and development,
manufacturing, marketing, financial, technological, personnel and managerial
resources than we have, and therefore have the potential to successfully develop
and commercialize products that are more effective or less expensive than ours.
The research and development efforts of others may render our research and
product development efforts obsolete or noncompetitive.

If we cannot protect our intellectual property, other companies could use our
technology in competitive products. If we infringe the intellectual property
rights of others, other companies could prevent us from developing or marketing
our products.

We seek patent protection for our drug candidates so as to prevent
others from commercializing equivalent products in substantially less time and
at substantially lower expense. The pharmaceutical industry places considerable
importance on obtaining patent and trade secret protection for new technologies,
products and processes. Our success will depend in part on our ability and that
of parties from whom we license technology to:

--defend our patents and otherwise prevent others from infringing on our
  proprietary rights;
--protect trade secrets; and
--operate without infringing upon the proprietary rights of others, both in the
  United States and in other countries.

The patent position of firms relying upon biotechnology is highly uncertain and
involves complex legal and factual questions for which important legal
principles are unresolved. To date, the United States Patent and Trademark
Office ("USPTO") has not adopted a consistent policy regarding the breadth of
claims that the USPTO allows in biotechnology patents or the degree of
protection that these types of patents afford. As a result, there are risks that
we may not develop or obtain rights to products or processes that are or may
seem to be patentable.

Even if we obtain patents to protect our products, those patents may not be
sufficiently broad and others could compete with us.

We, or the parties licensing technologies to us, have filed various United
States and foreign patents applications with respect to the products and
technologies under our development and the USPTO and foreign patent offices have
issued patents with respect to our products and technologies. These patent
applications include international applications filed under the Patent
Cooperation Treaty. Our pending patent applications, those we may file in the
future or those we may license from third parties may not result in the USPTO or
foreign patent office issuing patents. Also, if patent rights covering our
products are not sufficiently broad, they may not provide us with sufficient
proprietary protection or competitive advantages against competitors with
similar products and technologies. Furthermore, if the USPTO or foreign patent
offices issue patents to us or our licensors, others may challenge the patents
or circumvent the patents, or the patent office or the courts may invalidate the
patents. Thus, any patents we own or license from or to third parties may not
provide any protection against competitors. In particular, our issued and
pending patents relating to SuperVent(TM) solely cover relatively high
concentrations of tyloxapol.

Intellectual property rights of third parties could limit our ability to market
our products.

Our commercial success also significantly depends on our ability to operate
without infringing the patents or violating the proprietary rights of others.
The USPTO keeps United States patent applications confidential while the
applications are pending. As a result, we cannot determine which


                                       4


inventions third parties claim in pending patent applications that they have
filed. We may need to engage in litigation to defend or enforce our patent and
license rights or to determine the scope and validity of the proprietary rights
of others. It will be expensive and time consuming to defend and enforce patent
claims. Thus, even in those instances in which the outcome is favorable to us,
such proceedings can result in the diversion of substantial resources from our
other activities. An adverse determination may subject us to significant
liabilities or require us to seek licenses that third parties may not grant to
us or may only grant at rates that diminish or deplete the profitability of such
products to us. An adverse determination could also require us to alter our
products or processes or cease altogether any related research and development
activities or product sales.

If we cannot meet requirements under our license agreements, we could lose the
rights to our products.

We depend on licensing arrangements to maintain rights to our products under
development. These agreements require us to make payments and satisfy
performance obligations in order to maintain our rights under these licensing
arrangements. In addition, we are responsible for the cost of filing and
prosecuting certain patent applications and maintaining certain issued patents
licensed to us. If we do not meet our obligations under our license agreements
in a timely manner, we could lose the rights to our proprietary technology.

We rely on confidentiality agreements that could be breached and may be
difficult to enforce.

Although we believe that we take reasonable steps to protect our intellectual
property, including the use of agreements relating to the non-disclosure of
confidential information to third parties, as well as agreements that purport to
require the disclosure and assignment to us of the rights to the ideas,
developments, discoveries and inventions of our employees and consultants while
we employ them, such agreements can be difficult and costly to enforce. Although
we seek to obtain these types of agreements from our consultants, advisors and
research collaborators, to the extent that they apply or independently develop
intellectual property in connection with any of our projects, disputes may arise
as to the proprietary rights to this type of information. In such a case, a
court may determine that the right belongs to a third party, and enforcement of
our rights can be costly and unpredictable. In addition, we will rely on trade
secrets and proprietary know-how that we will seek to protect in part by
confidentiality agreements with our employees, consultants, advisors or others.
We cannot assure you:

--that they will not breach these agreements;
--that any agreements we obtain would provide adequate remedies for this type of
  breach or that our trade secrets or proprietary know-how will not otherwise
  become known or competitors will not independently develop similar technology;
  or
--that our competitors will not independently discover our proprietary
  information and trade secrets.

If the parties we depend on for manufacturing our pharmaceutical products do not
timely supply these products, it may delay or impair our ability to develop and
market our products.

We rely on outside manufacturers, including Akorn, Inc., Genzyme
Pharmaceuticals, a division of the Genzyme Corporation, Avanti Polar Lipids,
Inc., and BACHEM California, Inc., for our drug substance and other active
ingredients for Surfaxin(R) and to produce appropriate clinical grade material
that meets standards for use in clinical studies for our products. We will also
rely on outside manufacturers for production of our products after marketing
approval. We may also enter into arrangements with other manufacturers for the
manufacture of materials for use in clinical testing and after marketing
approval.

Our outside manufacturers may not perform as they have agreed or may not remain
in the contract manufacturing business for a sufficient time to successfully
produce and market our product candidates. If we do not maintain important
manufacturing relationships, we may fail to find a replacement manufacturer or
to develop our own manufacturing capabilities. If we cannot do so, it could
delay or impair our ability to obtain regulatory approval for our products and
substantially increase our costs or deplete any profit margins. If we do find
replacement manufacturers, there can be no assurance that we will be able to
enter into agreements with them on terms and conditions favorable to us and,
there could be a substantial delay before a new facility could be qualified and
registered with the FDA and foreign regulatory authorities.

We may in the future elect to manufacture some of our products on our own. We do
not currently have a manufacturing facility, manufacturing experience or
manufacturing personnel. If we decide to manufacture products on our own and do
not successfully develop manufacturing capabilities, it will adversely affect
sales of our products.

In addition, the FDA and foreign regulatory authorities require manufacturers to
register manufacturing facilities. The FDA and corresponding foreign regulators
inspect these facilities to confirm compliance with GMP or similar requirements
that the FDA or corresponding foreign regulators establish. If our third-party
foreign or domestic suppliers or manufacturers of our products or, if we decide
to manufacture our products on our own, we, fail to comply with GMP requirements
or other FDA and comparable foreign regulatory requirements, it could adversely
affect our ability to market and develop our products.

Our lack of marketing and sales experience could limit our ability to generate
revenues from future product sales.

We do not have marketing and sales experience or marketing or sales personnel.
If we do not develop a marketing and sales force, then we will depend on
arrangements with corporate partners or other entities for the marketing and
sale of our products. We may not succeed in entering into any satisfactory third
party arrangements for the marketing and sale of our products. In addition, we
may not succeed in developing marketing and sales capabilities or we may not
have sufficient resources to do so. If we fail to establish marketing and sales
capabilities or fail to enter into arrangements with third parties, it will
adversely affect sales of our products.

We depend upon key employees and consultants in a competitive market for skilled
personnel. If we are unable to attract and retain key personal, it could
adversely affect our ability to develop and market our products.

We are highly dependent upon the principal members of our management team,
especially Robert J. Capetola, Ph.D., and our directors, as well as our
scientific advisory board members, consultants and collaborating scientists. We
have an employment agreement with Dr. Capetola that expires on December 31,
2005. We also have employment agreements with other key personnel with
termination dates in 2001 and 2002. Although these


                                       5


employment agreements generally provide for severance payments that are
contingent upon the applicable employee's refraining from competition with us,
the loss of any of these persons' services would adversely affect our ability to
develop and market our products and obtain necessary regulatory approvals, and
the applicable noncompete provisions can be difficult and costly to monitor and
enforce. Further, we do not maintain key-man life insurance.

Our future success also will depend in part on the continued service of our key
scientific and management personnel and our ability to identify, hire and retain
additional personnel, including marketing and sales staff. We experience intense
competition for qualified personnel, and the existence of non-competition
agreements between prospective employees and their former employers may prevent
us from hiring those individuals or subject us to suit from their former
employers.

While we attempt to provide competitive compensation packages to attract and
retain key personnel, some of our competitors are likely to have greater
resources and more experience than we have, making it difficult for us to
compete successfully for key personnel.

Our industry is highly competitive and we have less capital and resources than
many of our competitors, which may give them an advantage in developing and
marketing products similar to ours.

Our industry is highly competitive and subject to rapid technological
innovation. We compete with numerous existing companies intensely in many ways.
We expect new companies to enter our industry and we expect competition to
increase. Many of these companies have substantially greater research and
development, manufacturing, marketing, financial, technological, personnel and
managerial resources than we have. In addition, many of these competitors,
either alone or with their collaborative partners, have significantly greater
experience than we do in:

--developing products;
--undertaking preclinical testing and human clinical trials;
--obtaining FDA and other regulatory approvals or products; and
--manufacturing and marketingproducts.

Accordingly, our competitors may succeed in obtaining patent protection,
receiving FDA or comparable foreign approval or commercializing products before
us. If we commence commercial product sales, we will compete against companies
with greater marketing and manufacturing capabilities. These are areas in which,
as yet, we have limited or no experience. In addition, developments by our
competitors may render our product candidates obsolete or noncompetitive. Our
competitors may succeed in developing and marketing products that are more
effective than ours.

We also face, and will continue to face, competition from colleges,
universities, governmental agencies and other public and private research
organizations. These competitors are becoming more active in seeking patent
protection and licensing arrangements to collect royalties for use of technology
that they have developed. Some of these technologies may compete directly with
the technologies that we are developing. These institutions will also compete
with us in recruiting highly qualified scientific personnel. We expect that
therapeutic developments in the areas in which we are active may occur at a
rapid rate and that competition will intensify as advances in this field are
made. As a result, we need to continue to devote substantial resources and
efforts to research and development activities.

If product liability claims are brought against us, it may result in reduced
demand for our products or damages that exceed our insurance coverage.

The clinical testing of, marketing and use of our products exposes us to product
liability claims in the event that the use or misuse of those products causes
injury, disease or results in adverse effects. Use of our products in clinical
trials, as well as commercial sale, could result in product liability claims. In
addition, sales of our products through third party arrangements could also
subject us to product liability claims. We presently carry product liability
insurance relating to our clinical trials of SuperVent(TM) and Surfaxin(R).
However, this insurance coverage includes various deductibles, limitations and
exclusions from coverage, and in any event might not fully cover any potential
claims. We may need to obtain additional product liability insurance coverage
prior to initiating other clinical trials. We expect to obtain product liability
insurance coverage before commercialization of our proposed products; however,
such insurance is expensive and insurance companies may not issue this type of
insurance when we need it. We cannot provide assurance that we can obtain
adequate insurance in the future at an acceptable cost. Any product liability
claim, even one that was not in excess of our insurance coverage or one that is
meritless and/or unsuccessful, could adversely affect our cash available for
other purposes, such as research and development. In addition, the existence of
a product liability claim could affect the market price of our Common Stock.

We expect to face uncertainty over reimbursement and healthcare reform.

In both the United States and other countries, sales of our products will depend
in part upon the availability of reimbursement from third-party payors, which
include government health administration authorities, managed care providers,
and private health insurers. Third party payors are increasingly challenging the
price and examining the cost effectiveness of medical products and services. In
addition, significant uncertainty exists as to the reimbursement status of newly
approved health care products. Our products may not be considered cost
effective. Adequate third party reimbursement may not be available to enable us
to maintain price levels sufficient to realize an appropriate return on our
investment in the research and development of our products.

The United States and other countries continue to propose and pass legislation
designed to reduce the cost of healthcare. Accordingly, legislation and
regulations affecting the pricing of our products may change before the products
are approved for marketing to the public. Adoption of new legislation and
regulations could further limit reimbursement for our products. If third party
payors fail to provide adequate coverage and reimbursement rates for our
products, the market acceptance of the products may be adversely affected. In
that case, our business and financial condition will suffer.


                                       6


Directors, executive officers, principal stockholders and affiliated entities
own a significant percentage of our capital stock, and they may make decisions
that you do not consider to be in your best interest.

As of October 25, 2001, our directors, executive officers, principal
stockholders and affiliated entities beneficially owned, in the aggregate,
approximately 29% of our outstanding voting securities. As a result, if some or
all of them acted together, they would have the ability to exert substantial
influence over the election of our Board of Directors and the outcome of issues
requiring approval by our stockholders. This concentration of ownership may have
the effect of delaying or preventing a change in control of the Company that may
be favored by other stockholders. This could prevent transactions in which
stockholders might otherwise recover a premium for their shares over current
market prices.

The market price of our stock may be adversely affected by market volatility.

The market price of our Common Stock, like that of many other development stage
pharmaceutical or biotechnology companies, has been and is likely to be
volatile. In addition to general economic, political and market conditions, the
price and trading volume of our stock could fluctuate widely in response to many
factors, including:

--announcements of the results of clinical trials by us or our competitors;
--adverse reactions to products;
--governmental approvals, delays in expected governmental approvals or
  withdrawals of any prior governmental approvals or public or regulatory agency
  concerns regarding the safety or effectiveness of our products;
--changes in U.S. or foreign regulatory policy during the period of product
  development;
--developments in patent or other proprietary rights, including any third party
  challenges of our intellectual property rights;
--announcements of technological innovations by us or our competitors;
--announcements of new products or new contracts by us or our competitors;
--actual or anticipated variations in our operating results due to the level of
  development expenses and other factors;
--changes in financial estimates by securities analysts and whether our earnings
  meet or exceed such estimates;
--conditions and trends in the pharmaceutical and other industries;
--new accounting standards; and
--the occurrence of any of the risks described in these "Risk Factors."

The Company's Common Stock is listed for quotation on the NASDAQ SmallCap
Market. For the 12-month period ended October 25, 2001, the price of our Common
Stock has ranged from $2.00 to $6.375. We expect the price of our Common Stock
to remain volatile. The average daily trading volume in the Company's Common
Stock varies significantly. For the 12-month period ending October 25, 2001, the
average daily trading volume in our Common Stock was approximately 45,500 shares
and the average number of transactions per day was approximately 56. The
Company's relatively low average volume and low average number of transactions
per day may affect the ability of our stockholders to sell their shares in the
public market at prevailing prices and a more active market may never develop.

In addition, we cannot assure investors that we will be able to continue to
adhere to the strict listing criteria of the SmallCap Market. If the Common
Stock were no longer listed on the SmallCap Market, investors might only be able
to trade in the over-the-counter market in the Pink Sheets(R) (a quotation
medium operated by the National Quotation Bureau, LLC) or on the OTC Bulletin
Board(R) of the National Association of Securities Dealers, Inc (the "NASD").
This would impair the liquidity of our securities not only in the number of
shares that could be bought and sold at a given price, which might be depressed
by the relative illiquidity, but also through delays in the timing of
transactions and reduction in media coverage.

In the past, following periods of volatility in the market price of the
securities of companies in our industry, securities class action litigation has
often been instituted against such companies. If we face such litigation in the
future, even if meritless or unsuccessful, it would result in substantial costs
and a diversion of management attention and resources, which would negatively
impact our business.

A substantial number of our securities are eligible for future sale and this
could affect the market price for our stock and our ability to raise capital.

The market price of our Common Stock could drop due to sales of a large number
of shares of our Common Stock or the perception that these sales could occur. As
of October 25, 2001, there were 24,753,138 shares of Common Stock outstanding.
In addition, as of October 25, 2001, up to 6,383,791 shares of Common Stock were
issuable on exercise of outstanding options and warrants.

Holders of our stock options and warrants are likely to exercise them, if ever,
at a time when we otherwise could obtain a price for the sale of our securities
that is higher than the exercise price per security of the options or warrants.
This exercise, or the possibility of this exercise, may impede our efforts to
obtain additional financing through the sale of additional securities or make
this financing more costly, and may reduce the price of our Common Stock.

Anti-takeover provisions of our Certificate of Incorporation and Delaware law
could delay actual or potential changes of control, which could affect our
stockholders' ability to benefit from market fluctuations and changes in
management.

Our Certificate of Incorporation and Delaware law contain provisions that may
discourage transactions involving actual or potential changes in control. Our
Certificate of Incorporation allows us to issue shares of preferred stock
without any vote or further action by our stockholders. Our Board of Directors
has the authority to fix and determine the relative rights and preferences of
preferred stock. Our Board of Directors also has the authority to issue such
preferred stock without further stockholder approval. As a result, our Board of
Directors could authorize the issuance of a


                                       7


series of preferred stock that would grant to holders the preferred right to our
assets upon liquidation, the right to receive dividend payments before dividends
are distributed to the holders of Common Stock and the right to the redemption
of such shares, together with a premium, prior to the redemption of our Common
Stock. In addition, our Board of Directors, without further stockholder
approval, could issue large blocks of preferred stock to fend against unwanted
tender offers or hostile takeovers.

We are also subject to provisions of Delaware law that could delay or make more
difficult a merger, tender offer or proxy contest involving us. In particular,
we are subject to Section 203 of the Delaware General Corporation Law that
prohibits a Delaware corporation from engaging in any business combination with
any interested stockholder for a period of three years unless the Board of
Directors and stockholders approve the transactions in a prescribed manner. In
general, Section 203 defines an interested stockholder as any entity or person
beneficially owning 15% or more of the outstanding voting stock of the
corporation and any entity or person affiliated with or controlling or
controlled by this type of entity or person. The possible issuance of preferred
stock and the provisions of Delaware law may have the effect of preventing
changes in our management and could have the effect of discouraging others from
making tender offers for our securities even if the events could be beneficial
to our stockholders. As a consequence, they also may inhibit fluctuations, even
favorable ones, in the market price of our Common Stock that otherwise could
result from actual or rumored takeover attempts.

The information contained in this table reflects "beneficial" ownership of
common stock within the meaning of Rule 13d-3 under the Exchange Act. On October
25, 2001, the Company had 24,752,112 shares of common stock outstanding.
Beneficial ownership information reflected in the table includes shares issuable
upon the exercise of outstanding warrants issued by the Company at their initial
exercise prices.

Except as set forth below, none of the selling stockholders named in the
preceding table has had any position, office or other material relationship with
us or any of our affiliates within the past three years. Jesup & Lamont
Securities Corp. ("Jesup & Lamont"), was the placement agent for our private
placement that closed on October 1, 2001, through which all the selling
stockholders bought the Shares that are being registered hereby. Jesup &
Lamont's Shares represent shares of common stock that are issuable pursuant to
the placement warrant issued to it for acting as our placement agent. Gary B.
Davis, Peter Stern and Jacqueline Waterman are registered representatives of
Jesup & Lamont.

                              PLAN OF DISTRIBUTION

The shares of common stock covered by this prospectus (the "Shares") are
beneficially owned by the selling stockholders. The selling stockholders and any
of their pledgees, assignees and successors-in-interest (hereinafter
collectively referred to in this section as the "selling stockholders") may
offer and sell, at one time or from time to time, some or all of the Shares. We
have registered the Shares for sale by the selling stockholders so that the
Shares will be freely tradeable by them. Registration of the Shares does not
mean, however, that the Shares necessarily will be offered or sold. We will not
receive any proceeds from any offering or sale by the selling stockholders of
the Shares. We will pay all costs, expenses and fees in connection with the
registration of the Shares. The selling stockholders will pay all brokerage
commissions and similar selling expenses, if any, attributable to the sale of
the Shares.

The selling stockholders will act independently of us in making decisions with
respect to the timing, manner and size of each sale. The Shares may be sold by
or for the account of the selling stockholders at one time or from time to time
in transactions on the Nasdaq SmallCap Market, the over-the-counter market or
otherwise. These sales may be at fixed prices or prices that may be changed, at
market prices prevailing at the time of sale, at prices related to these
prevailing market prices or at negotiated prices. The Shares may be sold by
means of one or more of the following methods:

      --    in a block trade in which a broker-dealer will attempt to sell a
            block of Shares as agent but may position and resell a portion of
            the block as principal to facilitate the transaction;

      --    purchases by a broker-dealer as principal and resale by that
            broker-dealer for its account pursuant to this prospectus;

      --    on markets where our common stock is traded or in an exchange
            distribution in accordance with the rules of the exchange;

      --    through broker-dealers, that may act as agents or principals;

      --    directly to one or more purchasers;

      --    through agents;

      --    in connection with the loan or pledge of Shares to a broker-dealer,
            and the sale of the Shares so loaned or the sale of the Shares so
            pledged upon a default;

      --    in connection with put or call option transactions, in hedge
            transactions and in settlement of other transactions in standardized
            or over-the-counter options;

      --    through short sales of the Shares by the selling stockholders or
            counterparties to those transactions, in privately negotiated
            transactions; or

      --    in any combination of the above. In addition, any of the Shares that
            qualify for sale pursuant to Rule 144 under the Securities Act may
            be sold under Rule 144 rather than pursuant to this prospectus.

In effecting sales, brokers or dealers engaged by the selling stockholders may
arrange for other brokers or dealers to participate. The broker-dealer
transactions may include:


                                       9


      --    purchases of the Shares by a broker-dealer as principal and resales
            of the Shares by the broker-dealer for its account pursuant to this
            prospectus;

      --    ordinary brokerage transactions; or

      --    transactions in which the broker-dealer solicits purchasers.

If a material arrangement with any broker-dealer or other agent is entered into
for the sale of any Shares through a block trade, special offering, exchange
distribution, secondary distribution or a purchase by a broker or dealer, a
prospectus supplement will be filed, if necessary, pursuant to Rule 424(b) under
the Securities Act disclosing the material terms and conditions of these
arrangement.

The selling stockholders and any broker-dealers or agents participating in the
distribution of the Shares may be deemed to be "underwriters" within the meaning
of the Securities Act, and any profit on the sale of the Shares by the selling
stockholders and any commissions received by a broker-dealer or agents, acting
in this capacity, may be deemed to be underwriting commissions under the
Securities Act. The selling stockholders may agree to indemnify any agent or
broker-dealer that participates in transactions involving sales of the Shares
against certain liabilities, including liabilities arising under the Securities
Act.

The selling stockholders are not restricted as to the price or prices at which
they may sell their Shares. Sales of such Shares may have an adverse effect on
the market price of the common stock. Moreover, the selling stockholders are not
restricted as to the number of Shares that may be sold at any time, and it is
possible that a significant number of Shares could be sold at the same time,
which may have an adverse effect on the market price of the common stock.

               ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS

Article Eighth of our Certificate of Incorporation limits the liability of
directors to the maximum extent permitted by Delaware law. Delaware law provides
that directors of a corporation will not be personally liable for monetary
damages for breach of their fiduciary duties as directors, except for liability
for (i) any breach of their duty of loyalty to the corporation or its
stockholders, (ii) acts or omissions not in good faith or that involve
intentional misconduct or a knowing violation of law, (iii) unlawful payments of
dividends or unlawful stock repurchases or redemptions as provided in Section
174 of the Delaware General Corporation Law or (iv) any transaction from which
the director derives an improper personal benefit.

Our Bylaws provide that we shall indemnify our directors and officers, the
directors and officers of any of our subsidiaries and any other individuals
acting as directors or officers of any other corporation at our request, to the
fullest extent permitted by law.

We have entered into indemnification agreements with certain of our executive
officers containing provisions that may require us, among other things, to
indemnify such officers against liabilities that may arise by reason of their
status or service as officers other than liabilities arising from willful
misconduct of a culpable nature and to advance certain expenses incurred as a
result of any proceeding against them as to which they could be indemnified. We
have obtained directors' and officers' liability insurance. These provisions in
the Certificate of Incorporation and the By-Laws do not eliminate the officers'
and directors' fiduciary duty, and in appropriate circumstances, equitable
remedies such as injunctive or other forms of non-monetary relief will remain
available under Delaware law. In addition, each officer and director will
continue to be subject to liability for breach of such officer's or director's
duty of loyalty to us for acts or omissions not in good faith or involving
intentional misconduct, for knowing violations of law, for actions leading to
improper personal benefit to the officer or director and for payment of
dividends or approval of stock repurchases or redemptions that are unlawful
under Delaware law. The provisions also do not affect an officer's or director's
responsibilities under any other law, such as the federal securities laws or
state or federal environmental laws.

We, the undersigned Registrant (the "Registrant") hereby undertake:

      (1)   To file, during any period in which offers or sales are being made,
            a post-effective amendment to the Registrant Statement to:

            (i) Include any prospectus required by Section 10(a)(3) of the
            Securities Act;

            (ii) Reflect in the prospectus any facts or events arising after the
            effective date of the Registration Statement (or the most recent
            post-effective amendment thereof) that individually or in the
            aggregate represent a fundamental change in the information set
            forth in the Registration Statement; and

            (iii) Include any material information with respect to the plan of
            distribution not previously disclosed in the Registration Statement
            or any material change to such information in the Registration
            Statement;


                                      II-1


provided, however, that paragraphs (i) and (ii) do not apply if the information
required to be included in a post-effective amendment by those paragraphs is
contained in periodic reports filed by the Registrant pursuant to Section 13 or
15(d) of the Exchange Act that are incorporated by reference in the Registration
Statement.

      (2)   That, for the purpose of determining any liability under the
            Securities Act, each such post-effective amendment shall be deemed
            to be a new registration statement relating to the securities
            offered therein, and the offering of such securities at that time
            shall be deemed to be the initial bona fide offering thereof.

      (3)   To remove from registration by means of a post-effective amendment
            any of the securities being registered which remain unsold at the
            termination of the offering.
