It is important that your shares be represented and voted at the Annual Meeting. Whether you plan to attend the Annual Meeting or not, it is important that you promptly register your vote in accordance with the instructions set forth on the enclosed proxy card.

PROXY STATEMENT
FOR THE ANNUAL MEETING OF STOCKHOLDERS
To Be Held On May 15, 2006

QUESTIONS AND ANSWERS
ABOUT THIS PROXY MATERIAL AND VOTING

Why am I receiving these materials?

We sent you this proxy statement and the enclosed proxy card because the Board of Directors of ADVENTRX Pharmaceuticals, Inc. (sometimes referred to as the “Company” or “ADVENTRX”) is soliciting your proxy to vote at the Annual Meeting of Stockholders. You are invited to attend the annual meeting to vote on the proposals described in this proxy statement. However, you do not need to attend the meeting to vote your shares. Instead, you may simply complete, sign and return the enclosed proxy card, or if made available to you by your broker, bank or other agent, vote over the telephone or the Internet.

The Company intends to mail this proxy statement and accompanying proxy card on or about April 15, 2006 to all stockholders of record entitled to vote at the annual meeting.

Who can vote at the annual meeting?

Only stockholders of record at the close of business on March 24, 2006 will be entitled to vote at the annual meeting. On this record date, there were 68,846,978 shares of common stock outstanding and entitled to vote. A list of stockholders entitled to vote at the annual meeting will be available for inspection at the executive offices of the Company beginning 10 days before the annual meeting as well as during the meeting.

Stockholder of Record: Shares Registered in Your Name

If on March 24, 2006 your shares were registered directly in your name with ADVENTRX’s transfer agent, American Stock Transfer & Trust Company, Inc. , then you are a stockholder of record as of the record date. As such, you may vote in person at the meeting or vote by proxy. Whether or not you plan to attend the meeting, we urge you to fill out and return the enclosed proxy card to ensure your vote is counted.

Beneficial Owner: Shares Registered in the Name of a Broker or Bank

If on March 24, 2006 your shares were held in an account at a brokerage firm, bank, dealer, or other similar organization, then you are the beneficial owner of shares held in “street name” and these proxy materials are being forwarded to you by that organization. The organization holding your account is considered the stockholder of record for purposes of voting at the annual meeting. As a beneficial owner, you have the right to direct your broker or other agent on how to vote the shares in your account. You are also invited to attend the annual meeting. However, since you are not the stockholder of record, you may not vote your shares in person at the meeting unless you request and obtain a valid proxy from your broker or other agent.

What am I voting on?

There are two matters scheduled for a vote:

	1.		To elect six members to our board of directors to hold office until the next Annual Meeting of Stockholders or until their respective successors have been elected or appointed and qualified; and
	2.		To ratify the Audit Committee’s appointment of J.H. Cohn LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2006.

How do I vote?

You may either vote “For” all the nominees to the Board of Directors or you may withhold voting for any nominee you specify or you may withhold your vote from all nominees as a group. For each of the other matters to be voted on, you may vote “For” or “Against” or abstain from voting. The procedures for voting are fairly simple:

Stockholder of Record: Shares Registered in Your Name

If you are a stockholder of record, you may vote in person at the annual meeting or vote by proxy using the enclosed proxy card. Whether or not you plan to attend the meeting, we urge you to vote by proxy to ensure your vote is counted. You may still attend the meeting and vote in person if you have already voted by proxy.

	•		To vote in person, come to the annual meeting and we will give you a ballot when you arrive.
	•		To vote using the proxy card, simply complete, sign and date the enclosed proxy card and return it promptly in the envelope provided. If you return your signed proxy card to us before the annual meeting, the proxies named in the proxy card will vote your shares as you direct.

Beneficial Owner: Shares Registered in the Name of Broker or Bank

If you are a beneficial owner of shares registered in the name of your broker, bank, or other agent, you should have received a proxy card or voting instruction form with these proxy materials from that organization rather than from ADVENTRX along with instructions on how to indicate your voting choices. Simply complete and mail the proxy card or voting instruction form to that organization to ensure that your vote is counted. Alternatively, you may vote by telephone or over the Internet if these arrangements are provided by your broker, bank or other agent. To vote in person at the annual meeting, you must obtain a valid proxy from your broker, bank, or other agent. Follow the instructions from your broker, bank or agent included with these proxy materials, or contact them to request a proxy.

How many votes do I have?

On each matter to be voted upon, you have one vote for each share of common stock you own as of March 24, 2006.

What if I return a proxy card but do not make specific choices?

If you return a signed and dated proxy card without marking any voting selections, your shares will be voted “For” the election of all six nominees for director, and “For” the other proposal. If any other matter is properly presented at the meeting, the proxies (named on your proxy card) will vote your shares using their best judgment.

Who is paying for this proxy solicitation?

We will pay for the entire cost of soliciting proxies. In addition to these mailed proxy materials, our directors, our employees and ADP Brokerage Services Group may also solicit proxies in person, by telephone, or by other means of communication. Directors and employees will not be paid any additional compensation for soliciting proxies, but ADP Brokerage Services Group will be paid its customary fee of approximately $5,000 plus out-of-pocket expenses if it solicits proxies. ADP Brokerage Services Group has mailed a search notice to banks, brokers and nominees to distribute proxy materials on behalf of brokers, banks and nominees to beneficial holders and solicit their proxy responses.

What does it mean if I receive more than one proxy card?

If you receive more than one proxy card, your shares are registered in more than one name or are registered in different accounts. Please complete, sign and return each proxy card to ensure that all of your shares are voted.

Can I change my vote after submitting my proxy?

Yes. You can revoke your proxy at any time before the vote at the meeting. You may revoke your proxy in any one of three ways:

	•		You may submit another properly completed proxy card with a later date.
	•		You may send a written notice that you are revoking your proxy to ADVENTRX’s Corporate Secretary at 6725 Mesa Ridge Road, Suite 100, San Diego, California 92121.
	•		You may attend the annual meeting and vote in person. Simply attending the meeting will not, by itself, revoke your proxy.

How are votes counted?

Votes will be counted by the inspector of election appointed for the meeting. Abstentions will be counted towards the vote total for each proposal and will have the same effect as “Against” votes. “Broker non-votes” (described below) count towards the quorum but otherwise have no effect, and will not be counted towards the vote total for any proposal.

If you do not give instructions to your nominee, your nominee can vote your shares with respect to “discretionary” items, but not with respect to “non-discretionary” items. Discretionary items are proposals considered routine under the rules of the American Stock Exchange (“AMEX”). On non-discretionary items for which you do not give your

broker instructions, the shares will be treated as broker non-votes. Both the election of directors and the ratification of the selection of the independent registered public accounting firm are considered to be discretionary items.

How many votes are needed to approve each proposal?

•		For the election of directors, the 6 nominees receiving the most “For” votes (among votes properly cast in person or by proxy) will be elected.
•		To be approved, all other proposals must receive a “For” vote from the majority of shares present and entitled to vote either in person or by proxy. Abstentions and broker non-votes will have the same effect as an “Against” vote.

What is the quorum requirement?

A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if at least a majority of the outstanding shares are present in person or by proxy at the meeting. On the record date, there were 68,846,978 shares outstanding and entitled to vote.

Your shares will be counted towards the quorum only if you submit a valid proxy or attend the meeting. Abstentions and broker non-votes will be counted towards the quorum requirement. If there is no quorum, a majority of the votes present at the meeting may adjourn the meeting to another date. No notice of an adjourned meeting will be given unless the adjourned date is more than 30 days after the original date or unless we declare a new record date for the adjourned meeting.

How can I find out the results of the voting at the annual meeting?

Preliminary voting results will be announced at the annual meeting. Final voting results will be published in the Company’s quarterly report on Form 10-Q for the second quarter of 2006, available on the SEC’s website at http://www.sec.gov or on our website at http://www.adventrx.com.

COMPOSITION OF THE BOARD AND COMMITTEES

The Board of Directors is currently composed of six members. Each director’s term is subject to the election and qualification of his successor, or his earlier death, resignation or removal. The authorized number of directors may not be less than three or more than nine and may be established within that range by our Board of Directors. There are no family relationships among any of our directors or executive officers.

Majority of Independent Directors

A majority of the members of our Board of Directors are independent without giving effect to the special independence requirements regarding affiliate status that are applicable to audit committee members under Rule 10A-3(b)(1)(ii)(B) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). We consider a director generally independent if that director is not an officer or employee of the Company and our Board of Directors affirmatively determines that the director does not have a material relationship with us that would interfere with the exercise of his independent judgment. In determining the independence of our Audit Committee members our Board of Directors also applies the additional requirements set forth in Rule 10A-3(b)(1)(ii)(B) of the Securities Exchange Act of 1934 and determines whether any such committee member (i) has accepted any consulting, advisory, or other compensatory fee from us, whether directly or indirectly, or (ii) is an affiliate of us. Our Board consults with our legal counsel to ensure that the Board’s determinations are consistent with relevant securities and other laws and regulations regarding independence, including those set forth in pertinent listing standards of the AMEX, as in effect from time to time.

Consistent with these considerations, after review of all relevant transactions or relationships between each director, or any of his family members, and the Company, its senior management and its independent auditors, the Board has affirmatively determined that Ross Johnson, Mark Pykett, Michael Goldberg, Mark Bagnall and Keith Meister are independent directors, with the exception that Keith Meister would not be deemed independent for purposes of serving on our Audit Committee under Rule 10A-3(b)(1)(ii)(B) of the Securities Exchange Act of 1934.

Board Committees

Our Board of Directors has a standing Audit Committee, Compensation Committee and Nominating and Governance Committee. Our Audit Committee is comprised of Mark Bagnall (Chairman), Mark Pykett and Michael Goldberg, each of whom is independent, including under Rule 10A-3(b)(1)(ii)(B) of the Securities Exchange Act of 1934. Our Nominating and Governance Committee is comprised of Mark Pykett (Chairman), Michael Goldberg and Mark Bagnall. Our Compensation Committee is comprised of Michael Goldberg (Chairman), Mark Pykett, Mark Bagnall and Keith Meister, each of whom is independent.

Below is a description of each committee of the Board of Directors.

Audit Committee

Our Audit Committee oversees our corporate accounting and financial reporting process. For this purpose, the Audit Committee performs several functions. The Audit Committee evaluates the performance of and assesses the

qualifications of the independent auditors; determines and approves the engagement of the independent auditors; determines whether to retain or terminate the existing independent auditors or to appoint and engage new independent auditors; reviews and approves the retention of the independent auditors to perform any proposed permissible non-audit services; monitors the rotation of partners of the independent auditors on our audit engagement team as required by law; confers with management and the independent auditors regarding the effectiveness of internal controls over financial reporting; establishes procedures, as required under applicable law, for the receipt, retention and treatment of complaints received by us regarding accounting, internal accounting controls or auditing matters and the confidential and anonymous submission by employees of concerns regarding questionable accounting or auditing matters; reviews the financial statements to be included in our Annual Report on Form 10-K and our Quarterly Reports on Form 10-Q; and discusses with management and the independent auditors the results of the annual audit and the results of our quarterly financial statements. The responsibilities of our Audit Committee are described in the Audit Committee Charter adopted by our Board of Directors.

We believe that each member of our Audit Committee is able to read and understand fundamental financial statements, including balance sheets, income statements, and cash flow statements. In addition, we believe that each member of our Audit Committee an “audit committee financial expert” within the meaning of Item 401(h)(2) of Regulation S-K under the Securities Act of 1933, as amended, and that each member is financially sophisticated, in that he has past employment experience in finance or accounting, requisite professional certification in accounting, or any other comparable experience or background which results in the individual’s financial sophistication, including being or having been a chief executive officer, chief financial officer, other senior officer with financial oversight responsibilities.

In concluding that our Audit Committee members are “audit committee financial experts,” the Board of Directors determined that they each have:

(i) an understanding of generally accepted accounting principles and financial statements;

(ii) the ability to assess the general application of such principles in connection with the accounting for estimates, accruals and reserves;

(iii) experience preparing, auditing, analyzing or evaluating financial statements that present a breadth and level of complexity of accounting issues that are generally comparable to the breadth and complexity of issues that can reasonably be expected to be raised by our financial statements, or experience actively supervising one or more persons engaged in such activities;

(iv) an understanding of internal control over financial reporting; and

(v) an understanding of audit committee functions.

Designation of a person as an audit committee financial expert does not result in the person being deemed an expert for any purpose, including under Section 11 of the Securities Act of 1933. The designation does not impose on the person any duties, obligations or liability greater than those imposed on any other Audit Committee member or any other director and does not affect the duties, obligations or liability of any other member of the Audit Committee or Board of Directors.

Report of the Audit Committee
of the Board of Directors

The Company’s management is responsible for the preparation, presentation, and integrity of the Company’s financial statements, accounting and financial reporting principles, internal controls, and procedures designed to ensure compliance with accounting standards, applicable laws, and regulations. The Company’s independent auditors, J.H. Cohn LLP, are responsible for performing an independent audit of the consolidated financial statements and expressing an opinion on the conformity of those financial statements with generally accepted accounting principles. The following is the report of the Audit Committee with respect to the Company’s audited financial statements for the fiscal year ended December 31, 2005, included in the Company’s Annual Report on Form 10-K for that year.

The Audit Committee has reviewed and discussed these audited financial statements with the Company’s management. The Audit Committee has also discussed with the Company’s independent auditors, J.H. Cohn LLP, the matters required to be discussed by SAS 61 (Codification of Statements on Auditing Standards, AU Section 380) as amended, which includes, among other items, matters related to the conduct of the audit of the Company’s financial statements. Further, the Audit Committee has received the written disclosures and the letter from J.H. Cohn LLP required by Independence Standards Board Standard No. 1 (“Independence Discussions with Audit Committees”) as amended, and has discussed with J.H. Cohn LLP the independence of J.H. Cohn LLP from the Company.

Based on these reviews and discussions, the Audit Committee recommended to the Company’s Board of Directors that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2005 for filing with the Securities and Exchange Commission.

Compensation Committee

The Compensation Committee of the Board of Directors reviews and approves the overall compensation strategy and policies for the Company. The Compensation Committee reviews and approves corporate performance goals and objectives relevant to the compensation of the Company’s executive officers and other senior management; reviews and approves the compensation and other terms of employment of the Company’s Chief Executive Officer; reviews and approves the compensation and other terms of employment of the other executive officers; and administers the Company’s stock option and purchase plans, pension and profit sharing plans, stock bonus plans, deferred compensation plans and other similar programs. All members of the Company’s Compensation Committee are independent.

No member of our compensation committee and none of our executive officers has a relationship that would constitute an interlocking relationship with executive officers and directors of another entity.

Report of the Compensation Committee
on Executive Compensation

The Compensation Committee approves compensation objectives and policies for all employees and sets compensation for the Company’s executive officers.

Objectives and Policies

The Committee seeks to ensure that:

	§		Rewards are closely linked to Company-wide, area, team and individual performance;
	§		The interests of the Company’s employees are aligned with those of its stockholders through potential stock ownership; and
	§		Compensation and benefits are set at levels that enable the Company to attract, retain and motivate the highly qualified employees necessary to achieve the Company’s objectives.

Executive Officer Compensation Program Components. The Committee reviews the Company’s compensation program to ensure that salary levels and incentive opportunities are competitive and reflect the performance of the Company. The Company’s compensation program for the Chief Executive Officer and other executive officers currently consists of base salary and equity-based compensation in the form of stock options.

Base Salary. Base salary levels for the Chief Executive Officer and the other executive officers are determined, in part, through comparisons with local companies in the pharmaceutical industry and other companies with which the

Company competes for personnel. In addition, the Committee evaluates individual experience and performance and specific issues particular to the Company, such as creation of stockholder value and achievement of Company milestones. The Committee reviews each executive’s salary at least annually and may increase executives’ salaries in connection with the Committee’s annual review based on: (i) the individual’s increased contribution to the Company over the prior 12 months; (ii) the individual’s increased responsibilities over the prior 12 months; and (iii) any increase in median competitive pay levels.

Annual Incentive Compensation. In the last three years the Company has not awarded any annual cash incentive compensation to its named executive officers except that the Company paid a former Chief Executive Officer a $15,000 bonus in 2003. The Company does not currently have any cash incentive plan, program or guidelines for its executive officers or other employees. However, the Compensation Committee currently plans to formulate bonus guidelines for executive officers and other employees which would provide a direct financial incentive in the form of an annual cash bonus awarded based on the achievement during defined periods of time of specifically defined individual and corporate performance goals. We expect that a portion of the total possible cash incentive compensation would be based on the achievement of individual accomplishments and that the remaining portion would be based on the Company’s achievement of certain goals, measured both quarterly and annually. We would set bonus awards at a level competitive within the local pharmaceutical and high technology industries as well as among a broader group of technology companies of comparable size and complexity.

Equity-Based Incentive Compensation. The Compensation Committee believes that equity-based compensation in the form of stock options or other equity awards links the interests of employees and stockholders by focusing employees and management on increasing stockholder value. In May 2005, the Company’s stockholders approved the 2005 Equity Incentive Plan (the “Incentive Plan”). The Compensation Committee expects that it will grant options to executives and other employees when such persons join the Company and periodically thereafter in connection with changes in responsibilities, and, occasionally, to achieve equity within a peer group. The number of shares subject to each stock option or other equity grant will take into account or be based on anticipated future contribution and ability to impact corporate or business unit results, past performance or consistency within the employee’s peer group, prior option grants to the employee and the level of vested and unvested options. The Compensation Committee expects that these options will generally vest as to 25% of the total shares within one year after the date of grant and then monthly over the next three years.

Compensation of Chief Executive Officer. As reported in a current report on Form 8-K filed with the SEC on November 29, 2005, pursuant to a Lockup Agreement, dated November 22, 2005, among Evan Levine, our President and Chief Executive Officer, and Icahn Partners LP, Icahn Master Fund LP and High River Limited Partnership (collectively, the “Icahn Entities”), Mr. Levine agreed, among other things, not to accept or request any increase in, or cause the Company to increase, the amount of his compensation, including his base compensation and bonuses, without the prior written consent of a majority of the members of our Board of Directors, including Keith Meister, the director nominated to our Board of Directors pursuant to a Rights Agreement, dated July 27, 2005, among the Company, the Icahn Entities and other persons. Mr. Levine’s ability to accept from us any increase in his compensation or any cash or equity bonus would be subject to this Lockup Agreement.

After its review of all existing programs, the Committee believes that, with the adoption of the Incentive Plan, the Company’s compensation program for its executive officers is competitive with the compensation programs provided by other companies with which the Company competes.

Nominating and Governance Committee

Our Nominating and Governance Committee identifies prospective director candidates, recommends nominees for election to our Board of Directors, develops and recommends Board member selection criteria, considers committee member qualification, recommends corporate governance principles to the Board of Directors, and provides oversight in the evaluation of our Board of Directors and each committee. The responsibilities of our Nominating and Governance Committee are described in the Nominating and Governance Committee Charter approved by our Board of Directors, a current copy of which is available on the Company’s website at www.adventrx.com.

When there is a need to identify or evaluate a prospective nominee, our Nominating and Governance Committee undertakes a review process which may involve, among other things, candidate interviews, inquiries of the person or persons recommending the candidate, engagement of an outside firm to gather additional information or discussions with management and incumbent directors. In evaluating candidates, including current directors eligible for re-election, our Nominating and Governance Committee considers various factors that it considers necessary or

appropriate, including the size and composition of our Board of Directors and our committees, the needs of our Board of Directors and our committees, the candidate’s expertise and experience, the candidate’s independence and potential conflicts of interest, the candidate’s character and integrity, and the candidate’s existing commitments. Upon completion of its review and evaluation, our governance and nominating committee makes its recommendations to our Board of Directors regarding the candidate(s). After considering our governance and nominating committee’s recommendations, our Board of Directors determines and approves which candidate(s) shall be recommended for nomination for election to our Board of Directors, subject to stockholder approval.

Our Nominating and Governance Committee will consider candidates for nomination as director who are recommended by the Company’s stockholders and will not evaluate any candidate for nomination as director differently solely because the candidate was recommended by a stockholder. To recommend a prospective candidate for consideration by our Nominating and Governance Committee, stockholders of the Company should submit the candidate’s name and qualifications to the committee in writing at the following address: ADVENTRX Pharmaceuticals, Inc., 6725 Mesa Ridge Road, Suite 100, San Diego, California 92121, Attention: Secretary. The Secretary will then forward this information to our Nominating and Governance Committee. To date, the Company has not received any candidate nominations from any stockholder or group of stockholders.

Meetings of the Board of Directors

During the year ended December 31, 2005, our Board of Directors met five times, our Audit Committee met three times and our Compensation Committee met four times. In addition, the Board of Directors established a Pricing Committee composed of Evan Levine, Mark Bagnall and Mark Pykett for the purpose of approving the final terms of a financing we consummated in July 2005, including the purchase price of shares sold in that financing and the number of shares to be sold. The Pricing Committee met on one occasion in 2005. Our Board of Directors also acted by unanimous written consent on eight occasions during the year ended December 31, 2005. Each Board member attended 75% or more of the aggregate number of the meetings of the Board and of the committees on which he served held during the period for which he was a director or committee member, respectively, during the year ended December 31, 2005.

Stockholder Communications with the Board of Directors

We have a formal process by which stockholders may communicate with the Board or any of its directors. Stockholders who wish to communicate with the Board may do so by sending written communications addressed to the our Secretary at ADVENTRX Pharmaceuticals, Inc., 6725 Mesa Ridge Road, Suite 100, San Diego, California 92121. All communications will be compiled by our Secretary and submitted to the Board or the individual directors on a periodic basis. These communications will be reviewed by one or more of our employees designated by the Board, who will determine whether they should be presented to the Board. The purpose of this screening is to allow the Board to avoid having to consider irrelevant or inappropriate communications (such as advertisements or solicitations). All communications directed to the Audit Committee in accordance with our Code of Business Conduct and Ethics that relate to questionable accounting or auditing matters involving the Company will be promptly and directly forwarded to the Audit Committee.

Code of Ethics

We adopted a Code of Business Conduct and Ethics (the “Code”) that applies to all of our employees (including our executive officers) and directors. We will provide to any person without charge, upon request, a copy of the Code. Any such request must be made in writing to ADVENTRX Pharmaceuticals, Inc., c/o Investor Relations, 6725 Mesa Ridge Road, Suite 100, San Diego, California 92121.

Compensation of Directors

Until May 15, 2006, our non-employee directors other than our Chairman each receives a quarterly payment of $5,000 in consideration of service as a director and our Chairman, Ross Johnson, receives a quarterly payment of $6,250 in consideration of his service as Chairman.

Our Board of Directors approved revisions to the compensation payable to our directors that will become effective on May 15, 2006. Effective May 15, 2006, our non-employee directors other than our Chairman will each receive quarterly payments in consideration of their service as set forth below:

In addition to the above compensation, effective May 15, 2006, our non-employee directors will receive with respect to each meeting of the Board of Directors or any committee of the Board with a duration of more than 15 minutes, other than (i) the first four meetings of the Board held during each calendar year, (ii) the first four meetings of the Audit Committee held during each calendar year, (iii) the first two meetings of the Compensation Committee held during each calendar year, and (iv) the first meeting of the Nominating Committee held during each calendar year:

	*		$500 to each director for each such meeting of the Board or any committee of the Board of which such director is a member attended by such director via telephone conference call.

Pursuant to the terms of our 2005 Equity Incentive Plan, each non-employee director is automatically granted a nonstatutory stock option to purchase 50,000 shares of our common stock at the first meeting of the Board following each annual meeting of stockholders, provided that such director has served on the Board for at least the preceding six months. The exercise price per share of each of these automatic grants is equal to 105% of the fair market value of a share of common stock on the date the option is automatically granted.

OWNERSHIP OF SECURITIES

The following table sets forth certain information as of March 24, 2006, concerning the ownership of common stock by (i) each of our stockholders that we believe is the beneficial owner of more than 5% of the outstanding shares of common stock, (ii) each current member of our Board of Directors, (iii) each of our executive officers and (iv) all directors and executive officers as a group.

We determined beneficial ownership in accordance with Rule 13d-3 under the Exchange Act and included all shares over which the beneficial owner exercises voting or investment power. Options and warrants to purchase common stock that are presently exercisable or exercisable within 60 days of March 24, 2006 that are held by any person listed below are included in the total number of shares beneficially owned for such person and are considered outstanding for the purpose of calculating the percentage ownership only of such holder. We have relied on information supplied by our officers, directors and certain stockholders and on information contained in filings with the SEC in completing the table below. Except as otherwise indicated, and subject to community property laws where applicable, we believe, based on information provided by these persons or contained in filings with the SEC, that the persons named in the table have sole voting and investment power with respect to all shares of common stock shown as beneficially owned by them. The percentage of beneficial ownership of common stock is based on 68,846,978 shares of common stock outstanding as of March 24, 2006 and for any particular stockholder, the options or warrants described above held by that holder.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Since January 1, 2005, we have not entered into any material transaction with any of our directors, executive officers or holders of more than 5% of our common stock, or with any persons in which directors, executive officers or such stockholders have direct or indirect material interests, except as described in the following two paragraphs.

In July 2005, we entered into a Securities Purchase Agreement with (i) Icahn Partners LP, Icahn Partners Master Fund LP and High River Limited Partnership (the “Icahn Funds”); (ii) Viking Global Equities LP and VGE III Portfolio Ltd. (the “Viking Funds”), and (iii) certain other investors (the “Purchase Agreement”). Pursuant to the Purchase Agreement, we sold 4,324,324 shares of our common stock to the Icahn Funds for an aggregate purchase price of approximately $8,000,000 and issued to the Icahn Funds warrants to purchase 4,324,324 shares of our common stock at an exercise price of $2.26 per share. Pursuant to the Purchase Agreement, we also sold 3,783,783 shares of our common stock to the Viking Funds for an aggregate purchase price of approximately $7,000,000 and issued to the Viking Funds warrants to purchase 3,783,783 shares of our common stock at an exercise price of $2.26 per share. We believe that the Icahn Funds and the Viking Funds are each the beneficial holder of more than five percent of our outstanding common stock. We believe that Keith Meister, a member of our Board of Directors, may be deemed to be the beneficial owner of the shares beneficially owned by the Icahn Funds.

During 2004, we engaged Burnham Hill Partners to provide placement agent services to us in connection with the sale of certain of our securities. In connection with that engagement, we agreed to pay to Burnham Hill Partners a four percent cash commission on each cash exercise of warrants to purchase up to an aggregate of (i) 3,125,272 shares of Common Stock at $2.00 per share and (ii) 2,083,518 shares of Common Stock at $2.50 per share, which warrants were acquired by investors in transactions for which Burnham Hill Partners acted as placement agent. During 2005, we paid $84,378 to Burnham Hill Partners as cash commissions in connection with the cash exercise of a portion of these warrants. We believe that Matthew Balk, a person we believe is the beneficial holder of more than five percent of our outstanding common stock, is a partner of Burnham Hill Partners and therefore may have an indirect material interest in the amounts we have paid to Burnham Hill Partners. We do not know the nature or extent of Mr. Balk’s indirect interest in the amounts we paid to Burnham Hill Partners.

Aggregated Option Exercises in Last Fiscal Year and Fiscal Year-End Values

No executive officer or member of our Board of Directors exercised any of our stock options during the fiscal year ended December 31, 2005.

The following table provides information regarding the number of shares of our common stock covered by both exercisable and unexercisable stock options held by our named executive officers as of December 31, 2005, and the value of those options that were “in-the-money” as of December 31, 2005, which values represent the positive spread between the exercise price of any such options and the fair market value of our common stock as of December 31, 2005.

Employment Contracts

We have entered into employment offer letters with each of our named executive officers other than Mr. Levine, our Chief Executive Officer. Each offer letter with our named executed officers sets forth the named executive officer’s initial base salary amount and the proposed option grant we would recommend to our Board of Directors for approval. None of these offer letters indicates a specific term of employment, each officer is an “at-will” employee and each officer’s employment may be terminated by either party at any time. We have not entered into an employment offer letter or agreement with Mr. Levine; Mr. Levine is employed as an “at-will” employee. We currently have customary confidentiality and invention assignment agreements in place with the named executive officers. We do not have any compensatory plan or arrangement with any named executive officer that is activated upon the resignation, termination or retirement of any of these executive officers, or upon a change in control of us, except that the vesting of stock options held by our executive officers would accelerate in full in the event of a change of control, provided that the officer is employed as of the closing of such change of control and the stock option is not assumed or replaced by the successor or acquiring entity.

PERFORMANCE MEASUREMENT COMPARISON

The following graph shows the six-month cumulative total stockholder return (change in stock price plus reinvested dividends) assuming the investment of $100 on October 2, 2001 (the day of we first registered our common stock under Section 12 of the Exchange Act) in each of our common stock, the Amex Composite Index, the Amex Biotech Index and the Nasdaq Biotechnology Index through December 31, 2005. The comparisons in the table are required by the SEC and are not intended to forecast or be indicative of possible future performance of the Company’s common stock.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Exchange Act requires our directors, executive officers and persons who own more than 10% of our common stock to file with the SEC initial reports of ownership and reports of changes in ownership of our common stock and other equity securities of ours. Directors, executive officers and greater than 10% holders are required by SEC regulation to furnish us with copies of all Section 16(a) reports they file. Based solely on our review of Forms 3 and 4 received during 2005 and Forms 5 (or any written representations) received with respect to fiscal year 2005, we believe that all directors, executive officers and 10% stockholders complied with all applicable Section 16(a) filing requirements during 2005.

PROPOSAL 1

RATIFICATION OF SELECTION OF INDEPENDENT AUDITORS

The Audit Committee of the Board of Directors has selected J.H. Cohn LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2006 and has further directed that management submit the selection of independent registered public accounting firm for ratification by the stockholders at the annual meeting. J.H. Cohn LLP has audited the Company’s financial statements for the fiscal years ended December 31, 2005 and 2004.

Neither the Company’s bylaws nor other governing documents or law require such ratification. However, the Audit Committee is seeking ratification as a matter of good corporate practice. If the stockholders fail to ratify the selection, the Audit Committee will reconsider whether or not to retain that firm. Even if the selection is ratified, the Audit Committee in its discretion may direct the appointment of a different firm at any time if it determines that such a change would be in the best interests of the Company and its stockholders.

The affirmative vote of the holders of a majority of the shares present in person or represented by proxy and entitled to vote at the annual meeting will be required to adopt this proposal. Abstentions will have the same effect as negative votes.

We currently expect that representatives of J.H. Cohn LLP will be present at the Annual Meeting. We would give such representatives the opportunity to make a statement if they desire to do so and such representatives would likely be available to respond to appropriate questions.

Independent Auditors’ Fees

The following table shows the fees paid or accrued by us for the audit services provided by J.H. Cohn LLP for fiscal 2005 and 2004. During the fiscal years ended December 31, 2005 and 2004, no other fees were billed by J.H. Cohn LLP for information technology consulting or any other services.

		2005				2004
Audit Fees (1)		$	236,020			$	82,556
Audit-Related Fees		$	44,153			$	6,340
Tax Fees			—				—
All Other Fees		$	37,730				—
Total		$	317,903			$	88,896

Pre-Approval Policies and Procedures

The Audit Committee has adopted a policy and procedures for the pre-approval of audit and non-audit services rendered by our independent auditor, J.H. Cohn LLP. The Audit Committee generally pre-approves specified services in the defined categories of audit services, audit-related services, and tax services up to specified amounts. Pre-approval may also be given as part of the Audit Committee’s approval of the scope of the engagement of the independent auditor or on an individual explicit case-by-case basis before the independent auditor is engaged to provide each service. The pre-approval of services may be delegated to one or more of the Audit Committee’s members, but the decision must be reported to the full Audit Committee at its next scheduled meeting. The Audit Committee has determined that the rendering of the services other than audit services by J.H. Cohn LLP is compatible with maintaining the principal accountant’s independence.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS
A VOTE IN FAVOR OF PROPOSAL 2

STOCKHOLDER PROPOSALS FOR 2007 ANNUAL MEETING

Under rules of the SEC, to be considered for inclusion in the Company’s proxy statement relating to the 2007 Annual Meeting of Stockholders, stockholder proposals pursuant to Rule 14a-8 of Regulation 14A under the Exchange Act must be received a reasonable time before the date the Company begins to print and mail its proxy materials for the 2007 Annual Meeting of Stockholders, but in no event later than December 16, 2006. If we are not notified of a stockholder proposal by March 1, 2007, then the management personnel who have been appointed as proxies may have the discretion to vote against such stockholder proposal, even though such proposal is not discussed in the proxy statement.

All stockholder proposals and other submissions should be addressed to the attention of the Secretary at the principal office of the Company and contain the information required by the Company’s bylaws.

HOUSEHOLDING OF PROXY MATERIALS

The SEC has adopted rules that permit companies and intermediaries (such as brokers) to satisfy the delivery requirements for proxy statements and annual reports with respect to two or more stockholders sharing the same address by delivering a single proxy statement addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for stockholders and cost savings for companies.

This year, a number of brokers with account holders who are ADVENTRX stockholders will be “householding” our proxy materials. A single proxy statement will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that they will be “householding” communications to your address, “householding” will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in “householding” and would prefer to receive a separate proxy statement and annual report, please notify your broker or other nominee, and direct your written request to ADVENTRX Pharmaceuticals, Inc., 6725 Mesa Ridge Road, Suite 100, San Diego, California 92121, Attention: Chief Financial Officer, or call 858-552-0866. Stockholders who currently receive multiple copies of the proxy statement at their address and would like to request “householding” of their communications should contact their broker.

ANNUAL REPORT

A copy of our 2005 Annual Report has been mailed concurrently with this Proxy Statement to all stockholders entitled to notice of and to vote at the annual meeting. The 2005 Annual Report is not incorporated into this Proxy Statement and is not considered proxy solicitation material.

OTHER MATTERS

Our Board of Directors knows of no other matters to be presented for stockholder action at the Annual Meeting. However, if other matters do properly come before the Annual Meeting or any adjournments or postponements thereof, the proxy holders will vote in accordance with their best judgment.

Whether or not you intend to be present at the meeting, you are urged to fill out, sign, date and return the enclosed proxy at your earliest convenience.
