          ALTEON'S 2002 ANNUAL REPORT ACCOMPANIES THE PROXY STATEMENT.


                                  ALTEON INC.
                               170 WILLIAMS DRIVE
                            RAMSEY, NEW JERSEY 07446

                                PROXY STATEMENT

     We are furnishing this Proxy Statement in connection with our Annual
Meeting of Stockholders to be held on June 4, 2003, at the Sheraton Crossroads
Hotel, One International Boulevard, Mahwah, New Jersey 07430, at 9:00 A.M.,
local time, and at any adjournment or adjournments thereof. Stockholders of
record at the close of business on April 8, 2003, will be entitled to vote at
the meeting and at any adjournment of the meeting. As of April 8, 2003, there
were 35,900,841 shares of common stock issued and outstanding and entitled to
vote. Each share of common stock is entitled to one vote on any matter presented
at the meeting.

     You may vote in person at the meeting or by proxy. We recommend you vote by
proxy even if you plan to attend the meeting. You can always change your vote at
the meeting.

     Alteon's Board of Directors is asking for your proxy. Giving us your proxy
by properly signing and returning the accompanying proxy card means you
authorize us to vote your shares at the meeting in the manner you direct. You
may vote for both, one or neither of our director candidates. We will vote as
you direct.

     If you properly sign and return the enclosed proxy card but do not specify
how to vote, we will vote your shares (i) FOR the election of the nominees named
below as directors; (ii) FOR the ratification of the appointment of KPMG LLP to
serve as our independent accountants for the fiscal year ending December 31,
2003; and (iii) in the discretion of the persons named in the enclosed form of
proxy, on any other proposals which may properly come before the meeting or any
adjournment of the meeting.

     You may receive more than one proxy or voting card depending on how you
hold your shares. Shares registered in your name are covered by one card.
However, if you hold shares through someone else, such as a stockbroker, you may
receive material from them asking how you want to vote. Each proxy card should
be signed and returned to assure that all of your shares are voted.

     You may revoke your proxy any time before it is voted by submitting a new
proxy with a later date, by voting in person at the meeting or by notifying
Alteon's Secretary in writing. However, your mere presence at the meeting does
not revoke the proxy.

     In order to carry on the business of the meeting, we must have a quorum.
This means the holders of at least a majority of our common stock must be
represented at the meeting, either by proxy or in person. Votes that are
withheld and broker non-votes will be counted for purposes of determining the
presence or absence of a quorum.

     Directors are elected by a plurality vote, which means that the two
nominees receiving the most votes will be elected to fill the seats on the
Board. All other actions considered at the meeting, including an adjournment,
may be taken upon the favorable vote of a majority of the votes present in
person or represented by proxy at the meeting. Only votes cast "for" a matter
will constitute affirmatives votes. Votes withheld or abstentions, because they
are not cast "for" a particular proposal, will have the same effect as negative
votes or votes cast "against" such proposal. Proxies submitted by brokers that
do not indicate a vote for some of the proposals because such brokers do not
have discretionary voting authority on those proposals and have not received
instructions from their customers on those proposals (i.e., broker non-votes)
are not considered to be shares present for the purpose of calculating the vote
on such proposals and will not affect the outcome of such proposals.

     This Proxy Statement, together with the related proxy card, is being mailed
to you on or about April 23, 2003. Our Annual Report to Stockholders for the
year ended December 31, 2002, including financial statements, is being mailed
concurrently with this Proxy Statement to all stockholders of record as of April
8, 2003. In addition, we have provided brokers, dealers, banks, voting trustees
and their nominees, at our expense, with additional copies of the Annual Report
so that they may supply the material to beneficial owners as of April 8, 2003.

elected and qualify. The nominees for election to the Board of Directors are

nominees named above, unless otherwise specified in the proxy. All of the

COMMITTEES AND MEETINGS OF THE BOARD

     The Board of Directors has a Compensation Committee, which reviews salaries
and incentive compensation for employees of and consultants to Alteon, a
Nominating Committee, which reviews the qualifications of candidates and
proposes nominees to serve as directors on our Board of Directors and nominees
for membership on Board committees, and an Audit Committee, which reviews the
results and scope of the audit and other services provided by our independent
accountants. The Nominating Committee does not consider nominees recommended by
stockholders. In 2002, the Audit, Nominating and Compensation Committees were
comprised of Marilyn G. Breslow, Alan J. Dalby, Edwin D. Bransome, Jr., M.D.,
David McCurdy, Thomas A. Moore, George M. Naimark, Ph.D., and Mark Novitch, M.D.
All of the members of the Audit Committee are independent, as such term is
defined by Section 121A of the American Stock Exchange listing standards. The
Audit Committee, Nominating Committee and Compensation Committee each held two
meetings during the year ended December 31, 2002. There were six meetings of the
Board of Directors in 2002. With the exception of Marilyn Breslow, each of the
incumbent directors attended at least 75% of the aggregate of (1) the total
number of meetings of the Board of Directors (held during the period for which
he or she was a director) and (2) the total number of meetings held by all
committees of the Board on which he or she served during the periods that he or
she served. We have adopted a written charter for the Audit Committee.

COMPENSATION OF DIRECTORS

     All of the directors are reimbursed for their expenses for each Board and
committee meeting attended. Directors who are not compensated as Alteon
employees receive $1,500 per meeting attended in person and $1,000 for each
meeting attended by telephone for their service to the Board. Non-compensated
directors also receive, upon the date of their election or re-election to the
Board and on the dates of the next two Annual Meetings of Stockholders (subject
to their continued service on the Board of Directors), a stock option to
purchase 20,000 shares of common stock (subject to adjustment if they received
stock options upon appointment to the Board between Annual Meetings of
Stockholders to fill a vacancy or newly created directorship) at an exercise
price equal to the fair market value of the common stock on the date of grant.
Each of these options will vest and become exercisable on the date of Alteon's
first Annual Meeting of Stockholders following the date of grant, subject to the
director's continued service on the Board.

Marilyn G. Breslow, David McCurdy, Thomas A. Moore, George M. Naimark, Ph.D.,
and Mark Novitch, M.D. None of the members of the Compensation Committee was an

COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

  General Policies

     The Compensation Committee (the "Committee") of the Board of Directors is
responsible for establishing and monitoring the general compensation policies
and compensation plans of Alteon, as well as the specific compensation levels
for executive officers. The Committee also acts as the Administrator under
Alteon's Amended and Restated 1987 Stock Option Plan and Amended 1995 Stock
Option Plan, and, from time to time, grants options under such Plans.

     Under the supervision of the Committee, Alteon has developed and
implemented compensation policies, plans and programs which (1) provide a total
compensation package which is intended to be competitive within the industry so
as to enable Alteon to attract and retain high-caliber executive personnel, and
(2) seek to align the financial interests of Alteon's employees with those of
its stockholders by relying heavily on long-term incentive compensation that is
tied to performance.

     The primary components of executive compensation include base salary and
long-term equity incentives in the form of stock options. Alteon relies on
long-term incentive compensation (i.e., stock options) to motivate the executive
officers and other employees. This allows Alteon to retain cash for research and
development projects. In determining the size of stock option grants to
individual executives, the Committee considers a number of factors, including
the following: the level of an executive's job responsibilities; the executive's
past performance; the size and frequency of grants by comparable companies; the
executive's salary level; the need to provide incentive for the purpose of
retaining qualified personnel in light of our current conditions and prospects;
the size of any prior grants; and the achievement of designated milestones by
the executive. The Committee assigns no specific weight to any of the foregoing
(other than achievement of designated milestones by the executive in cases where
the executive's employment agreement provides for a grant of a specific size
upon achievement of the milestone) when making determinations as to the size of
stock option grants.

     Executive officers are also eligible to earn an annual cash incentive
award, the amount of which is based upon (1) the position level of the executive
officer, and (2) the attainment of specific individual non-financial performance
objectives. The Committee sets the performance objectives at the beginning of
the fiscal year.

     The Chief Executive Officer is responsible for the development of the
annual salary plan for executive officers other than himself. The plan is based
on industry and peer group comparisons and national surveys and on performance
judgments as to the past and expected future contributions of the individuals.
To maintain a competitive level of compensation, Alteon targets base salary at
the upper percentiles of a comparative group composed of other biotechnology
companies. Base salary may exceed this level as a result of individual
performance. The Committee reviews the annual plan and makes recommendations to
the Board of Directors, with any modifications it deems appropriate. The
Committee believes it has established executive compensation levels which are
competitive with companies in the industry, taking into account individual
experience, performance of both Alteon and the individual, company size,
location and stage of development.

  Compensation of the Chief Executive Officer

     Mr. Moch's compensation was determined on the basis of his expertise and
experience, which include over 20 years of experience in the biotechnology and
venture capital fields. Mr. Moch received a base salary of $340,000 in 2002. In
2001, in connection with the extension of his employment agreement to December
2004, Mr. Moch received options to purchase 500,000 shares of Alteon's common
stock at an exercise price of $2.60 per share, which was the fair market value
of Alteon's common stock on the date of grant. Of the total number of shares
underlying this option, 300,000 vest in equal monthly installments over a
thirty-six month period, and 200,000 vest in a lump sum in December 2006,
subject to accelerated vesting on December 14, 2004 in the event that the
average fair market value for Alteon's common stock reaches certain specified
target prices. The Committee believes that Mr. Moch's compensation arrangements
reflect the compensation package necessary to retain his services for Alteon in
light of Alteon's current condition and prospects and is commensurate with his
expertise and experience as well as with compensation offered by comparable
biotechnology companies.

                                        8


     Effective January 1, 1994, the Internal Revenue Code does not permit
corporations to deduct payment of certain compensation in excess of $1,000,000
to the chief executive officer and the four other most highly paid executive
officers. All compensation paid to our executive officers for 2002 will be fully
deductible, and the Committee anticipates that amounts paid as cash compensation
will continue to be fully deductible because the amounts are expected to be less
than the $1,000,000 threshold. Under certain circumstances, the executive
officers may realize compensation upon the exercise of stock options granted
under our stock option plans which would not be deductible by Alteon. Alteon
expects to take such action as is necessary to qualify its stock option plans as
"performance-based compensation," which is not subject to the limitation, if and
when the Committee determines that the effect of the limitation on deductibility
warrants such action.

                             AUDIT COMMITTEE REPORT

     The Audit Committee's powers and responsibilities and the qualifications
required of each of its members, are set forth in the Audit Committee Charter.

RESPONSIBILITIES

     The Audit Committee is responsible for reviewing the results and scope of
the audit and other services provided by Alteon's independent accountants.
Management is solely responsible for the financial statements and the financial
reporting process, including the system of internal controls, and has
represented to the Audit Committee and the Board of Directors that the financial
statements discussed below were prepared in accordance with accounting
principles generally accepted in the United States of America appropriate in the
circumstances and necessarily include some amounts based on management's
estimates and judgments. Alteon's independent accountants are responsible for
auditing these financial statements and expressing an opinion on the conformity
of these financial statements, in all material respects, with accounting
principles generally accepted in the United States of America.

INDEPENDENCE

     As part of its responsibilities, the Audit Committee reviews the fees paid
to the independent accountants for non-audit services, if any, and considers the
effect of such services and the related fees on the independent accountants'
independence. As required by Independence Standards Board Standard No. 1, as
currently in effect, Alteon's independent accountants, KPMG LLP ("KPMG"), have
disclosed to the Audit Committee any relationships between it (and its related
entities) and Alteon (and its related entities), which, in its professional
judgment, may reasonably be thought to affect its ability to be independent. In
addition, KPMG has discussed its independence with the Audit Committee and
confirmed in a letter to the Audit Committee that, in its professional judgment,
it is independent of Alteon within the meaning of the Securities Act of 1933 and
the Securities Exchange Act of 1934.

RECOMMENDATION

     Acting pursuant to its Charter, the Audit Committee has reviewed Alteon's
audited annual financial statements for the year ended December 31, 2002, and
the related report by KPMG, and has discussed the audited financial statements
and report with management and with the independent accountants. The Audit
Committee has also discussed with management and the independent accountants the
matters required to be discussed by Statement on Auditing Standards 61, as
currently in effect. These matters include significant accounting policies,
management judgments and accounting estimates, management's consultation with
other accountants, and any difficulties encountered in performing the audit,
significant audit adjustment or disagreements with management. Based on the
review and discussions described above, the Audit Committee recommended to
Alteon's Board of Directors that the audited financial statements be included in
Alteon's annual report on Form 10-K for the fiscal year ended December 31, 2002,
for filing with the Securities and Exchange Commission.

EMPLOYMENT AGREEMENTS AND TERMINATION OF EMPLOYMENT ARRANGEMENTS WITH EXECUTIVE
OFFICERS

     Kenneth I. Moch entered into a three-year amended and restated employment
agreement with Alteon as of December 15, 1998. By letter agreement dated
December 3, 2001, the term of Mr. Moch's amended and restated employment
agreement was extended for an additional three years to December 15, 2004.
Pursuant to

                                        11


this letter agreement, Mr. Moch received stock options to purchase an aggregate
of 500,000 shares of our common stock. Under the amended and restated employment
agreement, Mr. Moch serves as our Chief Executive Officer and is entitled to an
annual salary of $300,000 (subject to annual review by the Board of Directors)
plus an annual bonus awarded at the discretion of the Board of Directors. Based
on the provisions of his agreement, in December 2001 the Board of Directors
approved an increase in Mr. Moch's base salary to $340,000.

     Robert C. deGroof, Ph.D., entered into a three-year employment agreement
with Alteon as of March 14, 2000. Under the employment agreement, Dr. deGroof
received stock options to purchase an aggregate of 250,000 shares of our common
stock. In addition, Dr. deGroof is entitled to an annual salary of $200,000
(subject to annual review by the Board of Directors) plus an annual bonus
awarded at the discretion of the Board of Directors. Pursuant to the agreement,
in December 2001, the Board of Directors approved an increase in Dr. deGroof's
base salary to $225,750.

     Judith S. Hedstrom entered into a three-year employment agreement with
Alteon as of February 11, 2002. Under the employment agreement, Ms. Hedstrom is
entitled to an annual salary of $215,000 (subject to annual review by the Board
of Directors) plus an annual bonus awarded at the discretion of the Board of
Directors. Pursuant to the agreement, Ms. Hedstrom received stock options to
purchase 200,000 shares of our common stock.

     Elizabeth A. O'Dell entered into a new employment agreement with Alteon as
of October 21, 2000. Under the terms of this agreement, which is due to expire
on December 31, 2003, Ms. O'Dell's salary is subject to annual review by the
Board of Directors. Ms. O'Dell is also eligible, at the discretion of the Board
of Directors, to receive an annual cash bonus. Based on the provisions of her
agreement, Ms. O'Dell received an annual salary of $170,000 for the calendar
year 2002.

     In addition to provisions in the above-described agreements requiring each
individual to maintain the confidentiality of our information and assign
inventions to us, such executive officers have agreed that during the terms of
their agreements and for one year thereafter, they will not compete with Alteon
by engaging in any capacity in any business which is competitive with our
business. The employment agreements of Mr. Moch, Dr. deGroof, Ms. Hedstrom and
Ms. O'Dell provide that either party may terminate the agreement upon 30 days'
prior written notice, subject to a salary continuation obligation of Alteon if
it terminates the agreements without cause. Mr. Moch will receive a 12-month
salary continuation and Dr. deGroof, Ms. Hedstrom and Ms. O'Dell will receive a
six-month salary continuation under such circumstances.

     All employment agreements between Alteon and its Vice Presidents provide
that all unvested stock options held by such Vice Presidents will vest and
become exercisable immediately in the event of a change in control of Alteon.

CHANGE IN CONTROL SEVERANCE BENEFITS PLAN

     In February 1996, we adopted the Alteon Inc. Change in Control Severance
Benefits Plan to protect and retain qualified employees and to encourage their
full attention, free from distractions caused by personal uncertainties and
risks in the event of a pending or threatened change in control of Alteon. The
Severance Plan provides for severance benefits to employees upon certain
terminations of employment after or in connection with a change in control of
Alteon as defined in the Severance Plan. Following a qualifying termination that
occurs as a result of a change in control, officers of Alteon will be entitled
to continuation of (i) their base salary for a period of 24 months, and (ii) all
benefit programs and plans providing for health and insurance benefits for a
period of up to 18 months. In addition, upon a change in control of Alteon, all
outstanding unexercisable stock options held by employees will become
exercisable.

401(k) PLAN

     We have a tax-qualified employee savings and retirement plan (the "401(k)
Plan") covering all of our employees. Pursuant to the 401(k) Plan, employees may
elect to reduce their current compensation by up to

                                        12


the statutorily prescribed annual limit ($12,000 in 2003) and have the amount of
such reduction contributed to the 401(k) Plan. The 401(k) Plan does not require
that we make additional matching contributions to the 401(k) Plan on behalf of
participants in the 401(k) Plan. However, in 1998, we began making discretionary
contributions at a rate of 25% of employee contributions up to a maximum of 5%
of their base salary. Contributions by employees to the 401(k) Plan and income
earned on such contributions are not taxable to employees until withdrawn from
the 401(k) Plan. The Trustees under the 401(k) Plan, at the direction of each
participant, invest the assets of the 401(k) Plan.

           RATIFICATION OF THE APPOINTMENT OF INDEPENDENT ACCOUNTANTS

     The Board has appointed, subject to stockholder ratification, KPMG LLP
("KPMG") to serve as our independent accountants for the fiscal year ending
December 31, 2003.

     KPMG served as our independent accountants for the fiscal year ended
December 31, 2002.

     If the stockholders do not ratify the Board's decision to appoint KPMG, we
may reconsider our selection. The affirmative vote of a majority of the shares
voted at the Annual Meeting is required for ratification.

     Representatives of KPMG are expected to be present at the Annual Meeting to
respond to appropriate questions from our stockholders. They will be given the
opportunity to make a statement if they wish to do so.

AUDIT FEES

     We were billed aggregate fees of $53,500 with respect to professional
services rendered by KPMG for (i) the audit of our annual financial statements
included in our annual report on Form 10-K for the year ended December 31, 2002,
and (ii) the review of the financial statements included in our quarterly
reports on Form 10-Q for the quarters ended March 31, June 30 and September 30,
2002.

FINANCIAL INFORMATION SYSTEMS DESIGN AND IMPLEMENTATION FEES

     KPMG did not perform any financial information systems design,
implementation or related services for us during the year ended December 31,
2002.

ALL OTHER FEES

     There were no fees billed for any other services rendered to us by KPMG
during the fiscal year ended December 31, 2002.

CHANGE IN ACCOUNTANTS

     On May 30, 2002, we dismissed Arthur Andersen LLP ("Andersen") as our
principal independent accountants and engaged KPMG to serve as Alteon's
principal independent accountants for the fiscal year ended December 31, 2002.
The Board of Directors reviewed whether Alteon should continue the retention of
Andersen in light of then recent events involving Andersen, and following its
review, authorized the engagement of KPMG in lieu of Andersen. Andersen's
reports on Alteon's financial statements for the years ended December 31, 2001
and 2000, did not contain an adverse opinion or a disclaimer of opinion and were
not qualified or modified as to uncertainty, audit scope or accounting
principles. During the years ended December 31, 2001 and 2000, and the period
from December 31, 2001 to the date of dismissal of Andersen,

                                        15


(i) there were no disagreements with Andersen on any matter of accounting
principles or practices, financial statement disclosure or auditing scope or
procedure which disagreements, if not resolved to Andersen's satisfaction, would
have caused Andersen to make reference to the subject matter of the
disagreement(s) in connection with its report, and (ii) there were no
"reportable events" within the meaning of the applicable rules of the SEC.
During the years ended December 31, 2001 and 2000, and the period from December
31, 2001 to the date of engagement of KPMG, neither Alteon nor anyone acting on
its behalf consulted with KPMG with respect to the application of accounting
principles to a specified transaction, either completed or proposed, or the type
of audit opinion that might be rendered on Alteon's financial statements or any
matter that was either the subject of disagreement or a reportable event.
Andersen's letter to the SEC stating its agreement with the statements made
herein is filed as an exhibit to our current report on Form 8-K filed with the
SEC on May 30, 2002.

     THE BOARD OF DIRECTORS RECOMMENDS THAT STOCKHOLDERS VOTE FOR THE
RATIFICATION OF THE APPOINTMENT OF KPMG LLP AS OUR INDEPENDENT ACCOUNTANTS.

                       SECTION 16(a) BENEFICIAL OWNERSHIP
                              REPORTING COMPLIANCE

     Section 16(a) of the Securities Exchange Act of 1934, as amended, requires
our officers and directors, and persons who own more than 10% of a registered
class of our equity securities, to file reports of ownership and changes in
ownership on Forms 3, 4 and 5 with the SEC. Officers, directors and greater than
10% stockholders are required by SEC regulation to furnish Alteon with copies of
all Forms 3, 4 and 5 they file.

     Based solely on our review of the copies of such forms we have received and
written representations from certain reporting persons that they were not
required to file Forms 5 for specified fiscal years, we believe that all our
officers, directors, and greater than 10% beneficial owners complied with all
filing requirements applicable to them with respect to transactions during
fiscal 2002.

                            STOCKHOLDERS' PROPOSALS

     Stockholders deciding to submit proposals for inclusion in our proxy
statement and form of proxy relating to our 2004 annual stockholders' meeting
must advise Alteon's Secretary of such proposals in writing by December 25,
2003. In addition, the proxy solicited by the Board of Directors for the 2004
annual stockholders' meeting will confer discretionary authority to vote on any
stockholder proposal presented at that meeting of which notice was untimely. In
accordance with our bylaws, notice of a proposal will be considered untimely,
unless Alteon's Secretary receives written notice of such proposal by March 6,
2004 (but not earlier than February 4, 2004).

                                 OTHER MATTERS

     The Board of Directors is not aware of any matter to be presented for
action at the meeting other than the matters referred to above and does not
intend to bring any other matters before the meeting. However, if other matters
should properly come before the meeting, it is intended that holders of the
proxies will vote thereon in their discretion.

                                    GENERAL

     The accompanying proxy is solicited by and on behalf of the Board of
Directors of Alteon, whose notice of meeting is attached to this Proxy
Statement, and the entire cost of such solicitation will be borne by Alteon.

of record by such brokers, nominees, custodians and other fiduciaries. We will
reimburse such persons for their reasonable expenses in connection therewith.
