                             ABOUT THIS PROSPECTUS

    This prospectus is part of a registration statement that we filed with the
Securities and Exchange Commission (SEC) using a "shelf" registration process.
Under this shelf process, we may offer, from time to time, in one or more
offerings, up to $120,000,000 in the aggregate of our common stock.

    This prospectus provides you with a general description of the securities we

                                  THE COMPANY

    Scios Inc. is a biopharmaceutical company developing novel treatments for
heart failure and inflammatory diseases. The company's disease-based technology
platform integrates expertise in protein biology with combinatorial and
medicinal chemistry to identify novel targets and rationally design large and
small-molecule compounds to treat cardiovascular and inflammatory diseases. Our
principal executive offices are located at 820 W. Maude Avenue, Sunnyvale, CA
94085, and our telephone number is (408) 616-8200.

    We are developing the following products:

NATRECOR-REGISTERED TRADEMARK- (NESIRITIDE)

    Our lead product candidate is Natrecor-Registered Trademark- (nesiritide).
We filed an amended New Drug Application (NDA) with the United States Food and
Drug Administration (FDA) in January 2001 seeking approval to market
Natrecor-Registered Trademark- for the treatment of acute decompensated heart
failure. The FDA has a six month period in which to respond to our filing. The
amended NDA responds to questions raised by the FDA in a non-approval letter
issued in April 1999 for Natrecor-Registered Trademark-. To provide further
information requested by the FDA, we conducted the VMAC (Vasodilation in the
Management of Acute Congestive heart failure) study for
Natrecor-Registered Trademark- in 498 acutely decompensated congestive heart
failure patients in the United States. The VMAC trial compared the effects of
Natrecor-Registered Trademark- against both placebo and intravenously
administered (IV) nitroglycerin, a standard therapy in the treatment of acute
decompenstated heart failure.

    The VMAC trial was successful in that we achieved our primary endpoints for
the trial. Specifically, in the VMAC trial, Natrecor-Registered Trademark- had a
statistically significant effect on the primary endpoint, reducing pulmonary
capillary wedge pressure (PCWP) in as little as 15 minutes, an effect that was
sustained for at least 48 hours without any loss of effectiveness (i.e.,
tachyphylaxis or tolerance). At three hours, patients treated with
Natrecor-Registered Trademark- had significant improvement in PCWP, compared
with those patients given placebo, and those patients given IV nitroglycerin. At
three hours, patients treated with Natrecor-Registered Trademark- had
significant improvement in their breathing, compared with those patients given
placebo. Using primarily a fixed dose infusion, Natrecor-Registered Trademark-
produced a more rapid improvement in hemodynamics than IV nitroglycerin, which
physicians need to titrate to achieve an effective dose. Significantly fewer
adverse events were reported in patients treated with Natrecor versus IV
nitroglycerin. The most common adverse event associated with Natrecor
administration was headache, which occurred significantly less often than in
patients treated with nitroglycerin (20% in the nitroglycerin patients vs. 9%
with Natrecor). In the VMAC study, symptomatic hypotension occurred in patients
treated with Natrecor at about the same rate as in patients treated with IV
nitroglycerin (4% and 5%, respectively) within 24 hours.


    In January 2001 we announced that, assuming FDA approval, we would launch
Natrecor-REGISTERED TRADEMARK- in the United States using a sales force
coordinated by Innovex LLP, a commercial solutions provider to the
biopharmacutical industry. Innovex will identify, hire, train and deploy a
dedicated cardiology and emergency medicine sales force of approximately 180
people to launch Natrecor. We will create a field support team of approximately
30 people. At the end of 2004 we can acquire this sales force from Innovex for a
nominal fee. In exchange for a royalty on Natrecor-REGISTERED TRADEMARK- sales
for five years (2003-2007) and a warrant to purchase 700,000 shares of Scios
common stock at a price of $20.00 per share that vests over 36 months, an
affiliated company of Innovex has agreed (assuming FDA approval) to fund
$30.0 million of our costs to launch Natrecor-REGISTERED TRADEMARK- over the
first 24 months and loan Scios up to $5.0 million. Of the $30.0 million,
$10.0 million will be paid to us in 2001 following the launch of Natrecor.


                                       3

INHIBITORS OF p38 KINASE


    We are also conducting a clinical trial of the lead compound (SCIO-469)
developed in our research program to discover small molecule compounds that
inhibit p38 map kinase. p38 map kinase in white blood cells is a key enzyme in
the inflammation pathway. Specifically, inhibition of p38 map kinase has been
shown to reduce the production of tissue necrosis factor (TNF), a primary
negative factor in various disease pathways. We believe inhibitors of p38 map
kinase represent a new approach to treating various diseases where inflammation
plays a central role. In the past several years, inhibition of TNF has been
established to be a treatment for rheumatoid arthritis by the introduction of
Enbrel-Registered Trademark- (etanercept) by Immunex Corporation and
Remicade-Registered Trademark-(infliximab) by Centocor, Inc., a subsidiary of
Johnson & Johnson. The Immunex and Centocor products are administered by
injection and infusion.


    We have developed and applied for patents on small molecule (non-protein)
compounds that inhibit p38 map kinase and block TNF production at the genomic
level. Our small molecule agents are intended to be given orally, which should
provide a significant advantage when treating a chronic disease such as
rheumatoid arthritis. We believe another key theoretical advantage to the Scios
approach resides in the ability of our oral product to be prescribed in a manner
that allows careful dosage adjustment. Such adjustment could lead to the same
level of clinical efficacy seen in the other agents mentioned above, but without
shutting down TNF entirely as TNF also plays a positive role in fighting
infections.

    We began our p38 map kinase research program in 1997. Our lead p38 map
kinase inhibitor is currently in Phase I human clinical trials to evaluate
bioavailability and pharmacodynamics in normal human volunteers. We currently
expect to begin our first Phase II trial in the second half of 2001. The
clinical indication we will initially target is rheumatoid arthritis because the
TNF reducing agents on the market have already demonstrated effectiveness
against this disease and the pathway to approval by the FDA has been clarified
by these other products. It appears that p38 map kinase inhibitors may also be
useful in treating other conditions that involve inflammation, such as
congestive heart failure and inflammatory bowel disease.

PARTNERED PROJECTS

    We also have commercial partners that are working to develop other products
we identified in our earlier research programs, including:

    - human basic fibroblast growth factor (FGF)--our licensee, Chiron
      Corporation, is conducting separate Phase II human clinical trials
      evaluating FGF as treatment for coronary artery disease and peripheral
      vascular disease. Our licensee, Kaken Pharmaceutical, Co., Ltd., has
      pending in Japan an approval to market an FGF-based product for the
      treatment of recalcitrant dermal ulcers.

    - glucagon-like peptide-1-Novo Nordisk A/S has completed Phase I human
      clinical trials of a GLP-1 analog that they are developing under a license
      from us as a treatment for type 2 diabetes.

                                  RISK FACTORS

    Investing in our securities involves risk. Please see the risk factors set
forth in the supplement which accompanies this prospectus as well as our
periodic reports on Form 10-K and Form 10-Q which have been filed with the SEC,
incorporated by reference into this prospectus and available on EDGAR at
http://www.sec.gov. Before making an investment decision, you should carefully
consider these risks as well as the other information contained or incorporated
by reference into this prospectus.


                              RECENT DEVELOPMENTS



    On February 8, 2001, we reported our financial results for the full year
2000 and the fourth quarter of 2000 as follows:



FULL YEAR 2000 FINANCIAL RESULTS



    Net revenues for the year ended December 31, 2000 were $12.7 million
compared to $28.4 million in 1999. The decrease in net revenues was primarily
attributed to $9.0 million in one-time milestone payments received in 1999 from
our corporate partners Chiron Corporation and Novo Nordisk A/S.



    Total costs and expenses for the year 2000 were $55.1 million versus
$52.7 million for the year ended December 31, 1999.



    We reported a net loss of $42.6 million or $1.12 per diluted share for the
year ended December 31, 2000, compared to a net loss of $20.1 million, or $0.53
per diluted share, for 1999. At December 31, 2000 we had approximately
39.1 million common shares outstanding, and approximately 5,000 shares of
preferred stock outstanding. If converted, the preferred stock would convert
into approximately 0.5 million common shares.



    At December 31, 2000, we had $71.5 million in cash, cash equivalents and
marketable securities.



FOURTH QUARTER FINANCIAL RESULTS



    Net revenues for the quarter ended December 31, 2000 were $3.6 million
compared to $12.4 million in the fourth quarter of 1999. The decrease in net
revenues was primarily attributed to $9.0 million in one-time milestone payments
received in 1999 from corporate partners Chiron Corporation and Novo Nordisk
A/S.



    Total costs and expenses for the fourth quarter of 2000 were $16.1 million
versus $11.7 million for the quarter ended December 31, 1999. The increase in
costs and expenses for the quarter was largely attributed to the clinical
development of Natrecor and SCIO-469.



    We reported a net loss of $12.3 million or $0.32 per diluted share for the
quarter ended December 31, 2000, compared to a net loss of $1.7 million, or
$0.04 per diluted share, for the comparative quarter in 1999.

               SPECIAL NOTE REGARDING FORWARD-LOOKING INFORMATION

    This prospectus, any prospectus supplement and the documents we incorporate
by reference contain forward-looking statements. We generally identify
forward-looking statements using words like "believe," "intend," "expect,"
"may," "should," "plan," "project," "contemplate," "anticipate" or similar
statements. We base these statements on our beliefs as well as assumptions we
made using information currently available to us. Because these statements
reflect our current views concerning future events, these statements involve
risks, uncertainties and assumptions. These risks, uncertainties and assumptions
are described in the risk factors we set forth in this prospectus as well as in
the reports that we file with the SEC that are incorporated by reference in this
prospectus or that may be contained in a prospectus supplement. Actual results
may differ significantly from the results discussed in these forward-looking
statements. We do not undertake to update our forward-looking statements or risk
factors to reflect future events or circumstances.

                                USE OF PROCEEDS

    Unless we specify otherwise in a prospectus supplement, we intend to use the
net proceeds from the sales of common stock to provide additional funds for our
operations and for other general corporate purposes, which may include but are
not limited to working capital, capital expenditures and the repayment or
refinancing of our debt.

                                    DILUTION

    If you invest in our common stock, your interest would be diluted to the
extent of the difference between the public offering price per share of our
common stock and the adjusted net tangible book value per share of our common
stock after this offering. We calculate tangible net book value per share by
dividing the net tangible book value, which equals total assets, less intangible
assets and total liabilities, by the number of outstanding shares of our common
stock.

    Assuming an offering price of $20.00 per share, our tangible net book value
at September 30, 2000 would have been $3.16 per share. This represents an
immediate increase in the tangible net book value per share of $2.63 per share
to existing stockholders and an immediate dilution of $16.84 share to new
investors.

    The following table illustrates this per share dilution:


                                                                   
Assumed offering price per share............................              $20.00
  Tangible net book value per share as of September 30,
    2000....................................................   $0.53

                                       6

                          DESCRIPTION OF CAPITAL STOCK

    Our authorized capital stock consists of 150,000,000 shares of common stock,
par value $0.001 per share and 20,000,000 shares of preferred stock, par value
$0.001 per share. As of December 31, 2000, there were 39,124,257 shares of
common stock outstanding and 4,991 shares of preferred stock outstanding.

VOTING RIGHTS

    Each share of common stock is entitled to one vote. The common stock votes
together as a single class on all matters presented for a vote of the
stockholders, except as provided under the Delaware General Corporation Law.

DIVIDENDS AND LIQUIDATION RIGHTS

    Each share of common stock is entitled to receive dividends, if, as and when
declared by the board of directors out of funds legally available for that
purpose. Subject to approval of certain holders of preferred stock in the event
of our dissolution, after satisfaction of amounts payable to our creditors and
distribution of any preferential amounts to the holders of outstanding preferred
stock, if any, holders of common stock are entitled to share ratably in the
assets available for distribution to the stockholders.

OTHER PROVISIONS

    There are no preemptive rights to subscribe for any additional securities
that we may issue, and there are not redemption provision or sinking fund
provisions applicable to the common stock. All outstanding shares of common
stock are legally issued, fully paid and nonassessable.

                              PLAN OF DISTRIBUTION

    We may sell the common stock to one or more underwriters for public offering
and sale by them or may sell the common stock to investors directly or through
agents. Any such underwriter or agent involved in the offer and sale of the
common stock will be named in the applicable prospectus supplement.

    We may offer and sell the common stock at a fixed price or prices, which may
be changed, at prices related to the prevailing market prices at the time of
sale or at negotiated prices for cash or assets in transactions that do not
constitute a business combination within the meaning of Rule 145 promulgated
under the Securities Act. The terms and conditions of any specific offer will be
set forth in the applicable prospectus supplement. In connection with the sale
of the common stock, underwriters or agents may be deemed to have received
compensation from us in the form of underwriting discounts or commissions and
may also receive commissions from purchasers of the common stock for whom they
may act as agent. Underwriters may sell common stock to or through dealers, and
such dealers may receive compensation in the form of discounts, concessions or
commissions from the underwriters and/or commissions from the purchasers from
whom they may act as agent.

    We also may, from time to time, authorize dealers, acting as our agents, to
offer and sell securities upon the terms and conditions as are set forth in the
applicable prospectus supplement. In connection with the sale of securities,
underwriters may receive compensation from us in the form of purchasers of the
securities for whom they may act as agent. Underwriters may sell securities to
or through dealers, and these dealers may receive compensation in the form of
discounts, concessions or commissions from the underwriters and/or commissions
from the purchasers for whom they may act as agent.

                                       7

    Any underwriting compensation paid by us to underwriters or agents in
connection with the offering of the common stock, and any discounts, concessions
or commissions allowed by underwriters to participating dealers, will be set
forth in the applicable prospectus supplement. Underwriters, dealers and agents
participating in the distribution of the common stock may be deemed to be
underwriters, and any discounts and commissions received by them and any profit
realized by them on resale of the common stock may be deemed to be underwriting
discounts and commissions, under the Securities Act. Underwriters, dealers and
agents may be entitled, under agreements entered into with us, to
indemnification against and contribution toward specified civil liabilities,
including liabilities under the Securities Act of 1933.

    To the extent relevant, a prospectus supplement may also contain a
description of transactions that underwriters, dealers or agents may engage in
during an offering for the purpose of stabilizing or maintaining the price of
the common stock.

    Some of the underwriters, dealers and agents and their affiliates may engage
in transactions with and perform services for us and our subsidiaries in the
ordinary course of our business.

                         NEW ACCOUNTING PRONOUNCEMENTS

    As described in our Quarterly Report on Form 10-Q for the quarter ended
September 30, 2000, the SEC issued Staff Accounting Bulletin No. 101 (SAB 101)
"Revenue Recognition in Financial Statements". We will adopt SAB 101 effective
January 1, 2000 upon issuance of our financial statements for the year ended
December 31, 2000.

    SAB 101 requires that our license and other up front fees received from
research collaborators be recognized as earned over the term of the agreement
unless the fee is in exchange for products delivered or services performed that
represent the culmination of a separate earnings process.

    We have completed our evaluation of the effects of SAB 101 and have
concluded that the cumulative effect of adoption as of January 1, 2000 is
immaterial to our results of operations and financial position. However, certain
revenue recognized in periods prior to January 1, 2000 would have been
recognized in different periods in accordance with the provisions of SAB 101. In
the year ended December 31, 1998 we recorded a $20,000,000 license fee in
connection with our Natrecor-Registered Trademark- commercialization agreement
with Bayer AG. Under SAB 101, $19,148,000 of the amount of this license fee has
been reallocated from 1998 to the year ended December 31, 1999, the year in
which the Bayer AG commercialization agreement was terminated. As a result of
this reallocation, the loss for the year ended December 31, 1998 increased by
$19,148,000 and the loss for the year ended December 31, 1999 decreased by
$19,148,000.

    Concurrently with the implementation of SAB 101, we will implement the
consensus reached in EITF 99-19 "Reporting Revenue Gross as a Principal Versus
Net As an Agent". The effect of this consensus will result in netting the
revenues received from our psychiatric pharmaceutical marketing business and
co-promotion commissions with related direct costs, as such it will have no
effect on our previously reported operating results.

                                       8

    The pro forma effects of implementing SAB 101 and EITF 99-19 on the results
we have previously reported for the nine months ended September 30, 2000 and
1999 and for the years ended December 31, 1999, 1998 and 1997 are presented
below:

ITEM 14. OTHER EXPENSES OF ISSUANCE AND DISTRIBUTION.


    The following table sets forth the fees and expenses in connection with the
issuance and distribution of the securities being registered. Except for the SEC
registration fee, all amounts are estimates.




                                                           
Securities and Exchange Commission registration fee.........  $ 30,000

Accounting fees and expenses................................  $ 20,000
Miscellaneous expenses......................................  $  5,000
    Total...................................................  $230,000



ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

    Under Section 145 of the General Corporation Law of the State of Delaware
(the "DGCL"), a corporation may indemnify its directors, officers, employees and
agents and its former directors, officers, employees and agents and those who
serve, at the corporation's request, in such capacities with another enterprise,
against expenses (including attorney's fees), as well as judgments, fines and
settlements in nonderivative lawsuits, actually and reasonably incurred in
connection with the defense of any action, suit or proceeding in which they or
any of them were or are made parties or are threatened to be made parties by
reason of their serving or having served in such capacity. The DGCL provides,
however, that such person must have acted in good faith and in a manner he or
she reasonably believed to be in (or not opposed to) the best interests of the
corporation and, in the case of a criminal action, such person must have had no
reasonable cause to believe his or her conduct was unlawful. In addition, the
DGCL does not permit indemnification in an action or suit by or in the right of
the corporation, where such person has been adjudged liable to the corporation,
unless, and only to the extent that, a court determines that such person fairly
and reasonably is entitled to indemnity for costs the court deems proper in
light of liability adjudication. Indemnity is mandatory to the extent a claim,
issue or matter has been successfully defended.

    Article IV of Scios's Amended and Restated Certificate of Incorporation, as
amended, provides that Scios will indemnify its directors and officers to the
full extent permitted by law and that no director shall be liable for monetary
damages to the Registrant or its stockholders for any breach of fiduciary duty,
except to the extent provided by applicable law (i) for any breach of the
director's duty of loyalty to the Registrant or its stockholders, (ii) for acts
or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) pursuant to Section 174 of the DGCL, or
(iv) for any transaction from which such director derived an improper personal
benefit. In addition, under indemnification agreements with its directors, the
Registrant is obligated, to the fullest extent permissible by the DGCL, as it
currently exists or may be amended, to indemnify and hold harmless its
directors, from and against all expense, liability and loss reasonably incurred
or suffered by such directors.

ITEM 17. UNDERTAKINGS.

    (a) The undersigned registrant hereby undertakes:

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

         (i) To include any prospectus required by Section 10(a)(3) of the
             Securities Act of 1933;

         (ii) To 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) which, individually or in the
              aggregate, represent a fundamental change in the information set
              forth in the registration statement. Notwithstanding the
              foregoing, any increase or decrease in volume of securities
              offered (if the total dollar value of securities offered would not
              exceed that which was registered) and any deviation from the low
              or high end of the estimated maximum offering range may be
              reflected in the form of prospectus filed with the Commission
              pursuant to Rule 424(b) if, in the aggregate, the changes in
              volume and price represent no more than 20 percent change in the
              maximum aggregate offering price, set forth in the "Calculation of
              Registration Fee" table in the effective registration statement;
              and

        (iii) To 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;

provided, however, that paragraphs (i) and (ii) above do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed with or furnished to the
Commission by the registrant pursuant to Section 13 or 15(d) of the Securities
Exchange Act of 1934 that are incorporated by reference into 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.

                                      II-2

    (b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act (and, where applicable, each filing of an employee
benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that
is incorporated by reference in the registration statement shall be deemed to be
a new registration statement relating to the securities offered herein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

    (c) The undersigned registrant hereby undertakes that:

        (1) For purposes of determining any liability under the Securities Act
    of 1933, the information omitted from the form of prospectus filed as part
    of this registration statement in reliance under Rule 430A and contained in
    a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or
    (4) or 497(h) under the Securities Act of 1933 shall be deemed to be part of
    this registration statement as of the time it was declared effective.


        (2) For the purpose of determining any liability under the Securities
    Act of 1933, each post-effective amendment that contains a form of
    prospectus 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.


    (d) The undersigned registrant hereby undertakes to deliver or cause to be
delivered with the prospectus, to each person to whom the prospectus is sent or
given, the latest annual report, to security holders that is incorporated by
reference in the prospectus and furnished pursuant to and meeting the
requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of
1934; and, where interim financial information required to be presented by
Article 3 of Regulation S-X is not set forth in the prospectus, to deliver, or
cause to be delivered to each person to whom the prospectus is sent or given,
the latest quarterly report that is specifically incorporated by reference in
the prospectus to provide such interim financial information.

    (e) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question of whether such indemnification by it is against
public policy as expressed in the Securities Act and will be governed by the
final adjudication of such issue.
