                                PROXY STATEMENT

                INFORMATION ABOUT THE ANNUAL MEETING AND VOTING

                         TO BE HELD ON FEBRUARY 5, 2002

THE ANNUAL MEETING

    This proxy statement is furnished in connection with the solicitation of
proxies by the Board of Directors of Advanced Magnetics, Inc. (the "Company")
for use at the Annual Meeting of Stockholders ("Annual Meeting") to be held at
the offices of the Company at 61 Mooney Street, Cambridge, Massachusetts 02138,
on Tuesday, February 5, 2002 and at any adjournment of the Annual Meeting. At
the Annual Meeting, a proposal to elect Messrs. Sheldon L. Bloch, Jerome
Goldstein, Michael D. Loberg, Edward B. Roberts and George M. Whitesides as
directors will be subject to a vote of stockholders.

WHO IS ENTITLED TO ATTEND AND VOTE AT THE ANNUAL MEETING?

    December 11, 2001 was the record date for the determination of stockholders
entitled to attend and vote at the Annual Meeting. Each stockholder is entitled
to one vote for each share of Common Stock held by such stockholder on the
record date. The proxy card provided with this proxy statement indicates the
number of shares of the Company's Common Stock that you own and are entitled to
vote.

WHAT CONSTITUTES A QUORUM AT THE MEETING?

    The representation in person or by proxy of at least a majority of the
outstanding shares of Common Stock entitled to vote at the Annual Meeting is
necessary to constitute a quorum for the transaction of business. As of the
record date, there were 6,633,895 shares of Common Stock of the Company
outstanding. For purposes of determining whether a quorum exists, votes withheld
from any nominee, abstentions and broker "non-votes" (described below) are
counted as present or represented.

HOW DO I VOTE BY PROXY?

    Your vote is very important to us. Whether or not you plan to attend the
Annual Meeting, we urge you to complete, sign and date the enclosed proxy card
and return it in the envelope provided. No postage is required if your proxy
card is mailed in the United States.

    Where you have specified a choice on the accompanying proxy card with
respect to the proposal, your shares will be voted in accordance with your
specifications. If you sign the proxy card but do not make specific choices,
your shares will be voted in favor of the proposal.

    If any other matter should be presented at the Annual Meeting upon which a
vote properly may be taken, your shares will be voted in accordance with the
judgment of the persons named in your proxy. At present, the Board of Directors
knows of no other matters to be presented at the Annual Meeting.

                                       1

WHAT IF I GET MORE THAN ONE PROXY CARD?

    This means that you have more than one account at the transfer agent and/or
with a broker. Your proxy card lists the number of shares you are voting. Please
sign and return all proxy cards to be sure that all of your shares are voted.

CAN I VOTE BY TELEPHONE OR ELECTRONICALLY?

    A large number of banks and brokerage firms are participating in the ADP
Investor Communication Services online program. This program provides eligible
stockholders the opportunity to vote via the Internet or by telephone. If your
bank or brokerage firm is participating in ADP's program, your voting form will
provide instructions. If your voting form does not reference Internet or
telephone information, please complete and return the paper proxy card in the
self-addressed, postage paid envelope provided.

HOW DO I VOTE IF MY SHARES ARE HELD BY MY BROKER?

    If your shares are held by your broker in "street name," you will need to
instruct your broker how to vote your shares in the manner provided by your
broker. Your broker may also offer electronic or telephonic voting, as described
above.

WHAT DISCRETION DOES MY BROKER HAVE TO VOTE MY SHARES HELD IN "STREET NAME"?

    New York Stock Exchange rules allow your broker to vote your shares with
respect to the election of directors, even if it does not receive instructions
from you, so long as your broker holds your shares in its name. There are,
however, certain matters with respect to which brokers do not have such
discretionary authority. Should such a matter come to a vote at the Annual
Meeting, your shares will not be voted on that matter. This is called a broker
"non-vote." Such "non-votes" will, however, be counted in determining whether
there is a quorum.

CAN I CHANGE MY VOTE AFTER I RETURN MY PROXY CARD?

    Yes. You may change your vote at any time before the proxy is exercised by
delivery of written notice to the Secretary of the Company "revoking" your
earlier vote, submitting to our transfer agent a properly completed and signed
proxy card with a later date or voting in person at the Annual Meeting.

HOW DO I VOTE IN PERSON?

    If you plan to attend the Annual Meeting and vote in person, we will give
you a ballot or a new proxy card when you arrive. However, if your shares are
held in the name of your broker, bank or other nominee, you must bring an
account statement or letter from the nominee indicating that you were the
beneficial owner of the shares on December 11, 2001, the record date for voting.

WHAT VOTE IS REQUIRED TO APPROVE THE PROPOSAL?

    FOR THE ELECTION OF DIRECTORS.  Directors are elected by a plurality of the
votes cast by stockholders entitled to vote at the Annual Meeting. If you do not
vote for a particular nominee, or you withhold authority for one or all
nominees, your vote will not count either "for" or "against" the nominee,
although it will be counted for purposes of determining whether there is a
quorum.

    FOR OTHER MATTERS.  The affirmative vote of the holders of a majority of the
shares of Common Stock present or represented, and voting, at the Annual Meeting
is required for approval of all other matters, if any, to be submitted to
stockholders at the Annual Meeting. Abstentions and broker "non-votes" are not
considered to have been voted on any matter and have the practical effect of
reducing

                                       2

the number of affirmative votes required to achieve a majority for such matter.
At present, the Board knows of no other matters to be presented for stockholder
action at the Annual Meeting.

HOW IS THE COMPANY SOLICITING PROXIES AND COUNTING VOTES?

    All costs of solicitation of proxies will be borne by the Company. In
addition, we have retained Georgeson Shareholder to act as a proxy solicitor in
connection with the Annual Meeting. We have agreed to pay approximately $10,000,
plus reasonable out of pocket expenses, to Georgeson Shareholder for proxy
solicitation services. In addition to solicitations by mail, our directors,
officers and regular employees, without additional remuneration, may solicit
proxies by telephone, telegraph and personal interviews. Brokers, custodians and
fiduciaries will be requested to forward proxy soliciting material to the owners
of stock held in their names, and we will reimburse them for their out-
of-pocket expenses in connection with this.

    Votes will be tabulated by American Stock Transfer and Trust Company as
Transfer Agent/ Registrar of the Company.

WHAT MATERIALS SHOULD I BE RECEIVING IN CONNECTION WITH THE MEETING?

    Our Annual Report, including audited financial statements for the fiscal
year ended September 30, 2001, is being mailed to you along with the mailing of
this proxy statement. This proxy statement and accompanying form of proxy will
first be mailed to stockholders on or about December 21, 2001.

                DEADLINE FOR SUBMISSION OF STOCKHOLDER PROPOSALS

    If you wish to submit proposals to be included in the Company's fiscal year
2002 proxy statement, we must receive them at our principal executive offices
not later than August 21, 2002. Proposals must satisfy the procedures set forth
in Rule 14a-8 under the Securities Exchange Act of 1934. The deadline for
providing us with timely notice of matters that you otherwise desire to
introduce at the Company's next annual meeting of stockholders is November 6,
2002. We may exercise our discretionary voting authority to direct the voting of
proxies on any matter submitted for a vote at the next annual meeting of
stockholders if notice concerning proposal of such matter was not received prior
to November 6, 2002. In order to curtail any controversy as to the date on which
a proposal was received by the Company, we suggest that you submit your
proposals by certified mail, return receipt requested.

                                STOCK OWNERSHIP

HOW MUCH STOCK DO THE COMPANY'S DIRECTORS, EXECUTIVE OFFICERS AND PRINCIPAL
  STOCKHOLDERS OWN?

    The following table sets forth information regarding the beneficial
ownership of the Company's Common Stock by certain individuals and entities. In
general, "beneficial ownership" includes those shares a person or entity has the
power to vote or transfer, and stock options that are exercisable currently or
within 60 days. As of December 11, 2001, there were 6,633,895 shares of Company
Common Stock outstanding. The following table shows, as of December 11, 2001,
the amount of Common Stock of the Company beneficially owned by:

    - each person known by the Company to own beneficially more than 5% of the
      Company's Common Stock;

    - each director;

    - the chief executive officer;

    - each of the three other most highly compensated executive officers of the
      Company, who were serving as executive officers as of September 30, 2001,
      whose annual compensation exceeded $100,000 (together with the chief
      executive officer, the "Executive Officers");

    - a former executive officer of the Company who would have qualified as an
      Executive Officer but for the fact that such individual was not serving as
      an executive officer as of September 30, 2001 (together with the Executive
      Officers, the "Named Officers"); and

    - all directors and Executive Officers of the Company as a group.

    The Board of Directors met four times during the fiscal year ended
September 30, 2001. Each director attended at least 75% of the meetings of the
Board and of the Committees on which he served.

WHAT COMMITTEES HAS THE BOARD ESTABLISHED?

    Under the Company's by-laws, the Board of Directors may designate committees
composed of members of the Board to exercise the power and authority of the
Board in the management of the business and affairs of the Company, subject to
limitations imposed by law. The Board of Directors has a standing Audit
Committee, composed of Sheldon L. Bloch, Michael D. Loberg, and Edward B.
Roberts. The Audit Committee oversees the financial controls and practices of
the Company and the performance and independence of its independent accountants
and reviews the Company's financial statements. The Audit Committee conducted
three formal meetings apart from Board of Directors meetings and acted once by
Written Consent during the fiscal year ended September 30, 2001. In accordance
with the rules and regulations of the Securities and Exchange Commission and the
American Stock Exchange, the Audit Committee Report can be found on page 13
hereof.

    The Board of Directors does not have standing nomination or compensation
committees or committees performing similar functions.

HOW ARE THE COMPANY'S DIRECTORS COMPENSATED?

    During the fiscal year ended September 30, 2001, directors received no cash
compensation for their services as directors, except for reimbursement of
expenses incurred in connection with attending meetings.

    Under the terms of the Company's 1992 Director Plan, (i) each person who was
a member of the Company's Board of Directors on November 5, 1991, and who was
not an employee or an officer of the Company, was automatically granted on
November 5, 1991 and November 5, 1996 an option to purchase 5,000 shares of the
Company's Common Stock and (ii) each person who becomes a member of the Board of
Directors after November 5, 1991 and who is not an employee or an officer of the
Company is automatically granted an option to purchase 5,000 shares of the
Company's Common Stock as of the date of such person's election to the Board of
Directors and will receive an option to purchase an additional 5,000 shares on
each successive fifth anniversary of such date if he or she is then a member of
the Board of Directors. The exercise price of options granted under the 1992
Director Plan is the fair market value of the Company's Common Stock on the date
the option is granted (subject to adjustment for any dividend, stock split or
other relevant change in the Company's capitalization). Each option granted
under the 1992 Director Plan first becomes exercisable with respect to 20% of
the shares subject to such option on the day preceding each annual anniversary
of the date of grant, until the option is exercisable with respect to all of the
shares subject thereto; provided that the vesting of options on each annual
vesting date is conditioned, with limited exceptions, upon the optionee having
continuously served as a member of the Board of Directors through such date. No
grants may be made under the 1992 Director Plan after November 4, 2001.

    Under the terms of the Company's 1993 Director Plan, (i) each person who was
a member of the Company's Board of Directors on November 10, 1992, and who was
not an employee or an officer of the Company, was automatically granted on
November 10, 1992 and November 10, 1998 an option to purchase 5,000 shares of
the Company's Common Stock and (ii) each person who becomes a member

                                       7

of the Board of Directors after November 10, 1992 and who is not an employee or
an officer of the Company is automatically granted an option to purchase 5,000
shares of the Company's Common Stock as of the date of such person's election to
the Board of Directors and will receive an option to purchase an additional
5,000 shares on each successive sixth anniversary of such date if he or she is
then a member of the Board of Directors. The exercise price of options granted
under the 1993 Director Plan is the fair market value of the Company's Common
Stock on the date the option is granted (subject to adjustment for any dividend,
stock split or other relevant change in the Company's capitalization). Each
option granted under the 1993 Director Plan first becomes exercisable with
respect to 20% of the shares subject to such option on the day preceding each
annual anniversary of the date of grant, until the option is exercisable with
respect to all of the shares subject thereto; provided that the vesting of
options on each annual vesting date is conditioned, with limited exceptions,
upon the optionee having continuously served as a member of the Board of
Directors through such date. No grants may be made under the 1993 Director Plan
after November 10, 2002.

    Directors are also eligible for option grants under the terms of the
Company's 1993 Stock Plan and 2000 Stock Plan.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

    Section 16(a) of the Exchange Act requires the Company's directors,
executive officers and holders of more than 10% of the Company's Common Stock
(collectively, "Reporting Persons") to file with the Securities and Exchange
Commission initial reports of ownership and reports of changes in ownership of
Common Stock of the Company. Such persons are required by regulations of the
Securities and Exchange Commission to furnish the Company with copies of all
such filings. Based on its review of the copies of such filings received by it
with respect to the fiscal year ended September 30, 2001, and written
representations from certain of its directors and executive officers, the
Company believes that all Reporting Persons complied with all Section 16(a)
filing requirements in the fiscal year ended September 30, 2001.

------------------------

(1) No stock appreciation rights ("SARs") were granted in the fiscal year ended
    September 30, 2001.

(2) Amounts reported in these columns represent amounts that may be realized
    upon exercise of the options immediately prior to the expiration of their
    term assuming the specified compounded rates of appreciation (5% and 10%) on
    the Company's Common Stock over the term of the options. These numbers are
    calculated based on rules promulgated by the Securities and Exchange
    Commission and do not reflect the Company's estimate of future stock price
    growth. Actual gains, if any, on stock option exercises and Common Stock
    holdings are dependent on the timing of such exercise and the future
    performance of the Company's Common Stock. There can be no assurance that
    the rates of appreciation assumed in this table can be achieved or that the
    amounts reflected will be received by the individuals.

(3) Options granted under the Company's 1993 Stock Plan at an exercise price
    equal to 110% of the fair market value of the Company's Common Stock on the
    date of grant. The options have a term of five years from the date of grant
    and become exercisable as to 25% of the shares on each of the first four
    anniversaries of the date of grant until such options are fully exercisable.

(4) Options granted under the Company's 1993 Stock Plan at an exercise price
    equal to the fair market value of the Company's Common Stock on the date of
    grant. The options have a term of ten years from the date of grant and
    become exercisable as to 25% of the shares on each of the first four
    anniversaries of the date of grant until such options are fully exercisable.

(1) No stock options or stock appreciation rights were exercised by the Named
    Officers in the fiscal year ended September 30, 2001.

(2) All options held by the Named Officers have an exercise price of greater
    than the fair market value at September 30, 2001 of the Company's Common
    Stock ($3.01 per share as quoted on the American Stock Exchange on
    September 28, 2001, the last trading day of fiscal 2001), and, therefore, no
    such options are "in-the-money."

           REPORT ON EXECUTIVE COMPENSATION BY THE BOARD OF DIRECTORS

WHAT IS THE COMPANY'S EXECUTIVE COMPENSATION PHILOSOPHY?

    The Board of Directors of the Company is responsible for establishing and
administering the Company's executive compensation programs. The Company's
executive compensation policies rely on regular cash salaries and significant
equity incentives in the form of stock options.

    Salaries of the five highest paid executives who served the Company during
the fiscal year ended September 30, 2001 are listed on the Executive
Compensation Summary table found on page 9. On an annual basis, the Board
reviews the salaries of its executive officers and, while it is not required to,
it may in its discretion increase the salaries. The Board has typically adjusted
the compensation of each of the executives by the same percentage amount. The
amount of the annual increases has historically reflected the Board's subjective
assessment of the salary level necessary for the Company to remain at the
approximate median in compensation levels when compared to other
biopharmaceutical companies of comparable size and geographical location (which
together comprise a subset of the Company's Peer Group Index referred to in the
Stock Performance Graph below), and the Board's subjective judgment as to
Company performance. In fiscal 2001, the Board determined the Company's
performance primarily by reference to the progress of the Company's product
development and marketing efforts, including the filing of an Investigational
New Drug Exemption with the U. S. Food and Drug Administration for one of the
Company's products in conjunction with the exploration of new market
opportunities for the Company's core technology. The Board determined to grant
the Named Officers the compensation disclosed in the Executive Compensation
Summary table found on page 9.

    In order to align the interests of executives and other employees with
stockholders and motivate them to work for the long-term growth of the Company,
the Company provides significant stock option grants to its employees.
Executives are typically considered every two years for stock option grants, and
it is the Company's policy to weight total compensation heavily toward equity
compensation through stock options. Options are generally granted at fair market
value and become exercisable ratably over a four-year period. The actual number
of stock options granted to executives is not determined pursuant to any
formula, but rather they are awarded subjectively by the Board in its
discretion. The Board determined to grant the Named Officers the number of
options disclosed in the Option Grants in Last Fiscal Year table found on
page 10.

HOW WAS THE COMPANY'S CHIEF EXECUTIVE OFFICER COMPENSATED IN FISCAL YEAR 2001?

    The compensation of the Chief Executive Officer has typically been adjusted
annually by the same percentage as the average percentage increase for all of
the Company's employees. In exercising its discretion, the Board takes into
consideration, among other things, the Company's progress in achieving the goals
of the Board of Directors (focusing in recent periods on the Company's product
development, clinical trial progress and marketing strategies), and the
compensation packages of executive officers of comparable companies of similar
size in the biopharmaceutical industry.

    As a result of the Company's performance and his individual contribution,
Jerome Goldstein was awarded the amounts reflected in the Executive Compensation
Summary table on page 9 in fiscal 2001.

          COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

    The Company does not have a Compensation Committee. The Board of Directors
was responsible for determining compensation of executive officers of the
Company. During the fiscal year ended September 30, 2001, Jerome Goldstein, the
Company's Chairman of the Board of Directors, Chief Executive Officer, President
and Treasurer, participated in the establishment and administration of the
Company's executive compensation programs. Mr. Goldstein abstained from voting
with respect to decisions concerning his compensation as an executive officer of
the Company.

    Mr. Jerome Goldstein, an executive officer of the Company, served as a
director of CompuCyte Corporation until September 2001. Mr. Sheldon L. Bloch, an
executive officer of CompuCyte Corporation until November 2001, joined the
Company's Board of Directors in April 2001.

                             AUDIT COMMITTEE REPORT

    The Audit Committee is composed of Sheldon L. Bloch, Michael D. Loberg and
Edward B. Roberts. No member of the Audit Committee is an officer or employee of
the Company, and aside from being a director of the Company, each is otherwise
independent of the Company (as independence is defined in the American Stock
Exchange's listing standards). In addition, each of the members of the Audit
Committee is financially literate, including at least one member who has
accounting or financial employment experience or other comparable experience or
background, as required by the American Stock Exchange. The Audit Committee
operates under a written charter adopted by the Board of Directors.

    The Audit Committee has reviewed the audited financial statements of the
Company at September 30, 2001, and September 30, 2000 and for each of the three
years ended September 30, 2001, and has discussed them with both management and
PricewaterhouseCoopers LLP, the Company's independent accountants. The Audit
Committee has reviewed with the independent accountants, who are responsible for
expressing an opinion on the conformity of the Company's audited financial
statements with generally accepted accounting principles, their judgments as to
matters related to the conduct of the audit of the Company's financial
statements and such other matters as are required to be discussed with the Audit
Committee by Statement on Auditing Standards No. 61, "Communications with Audit
Committees," as currently in effect. The Audit Committee has met with the
independent accountants, with and without management present, to discuss the
results of their examinations, their evaluations of the Company's internal
controls, and the overall quality of the Company's financial reporting. The
Audit Committee has received the written disclosures and the letter from the
independent accountants required by Independence Standards Board Standard No. 1,
"Independence Discussions with Audit Committees," as currently in effect, and
has discussed with PricewaterhouseCoopers LLP that firm's independence from
management and the Company and considered the compatibility of the accountants'
provision of information technology services and other non-audit services with
maintaining the accountants' independence.

    In reliance on the reviews and discussions referred to above, the Audit
Committee concluded that it would be reasonable to recommend, and on that basis
did recommend, to the Board of Directors (and the Board has approved) that the
audited financial statements be included in the Company's Annual Report on Form
10-K for the fiscal year ended September 30, 2001 for filing with the Securities
and Exchange Commission.
