PROXY STATEMENT

This Proxy Statement is furnished in connection with the solicitation of proxies by our Board of Directors to be voted at the Special Meeting of our stockholders which will be held at our offices located at 420 Lexington Avenue, Suite 1609, New York, New York, on ______, May ___, 2006 beginning at 11:00 a.m., and at any postponements or adjournments thereof on.
 
INFORMATION ABOUT THE SPECIAL MEETING AND VOTING

Q:
What is the purpose of the Special Meeting?
   
A:
In order to complete the development and commercialization of our current product candidates and to continue to fund our operations at current cash expenditure levels, it will be necessary for us to raise capital, including by the sale of our common stock, or securities convertible into or exercisable or exchangeable for our common stock, sometimes at a discount to the then current market price. Accordingly, at our Special Meeting, stockholders are being to ask to vote upon and approve the potential issuance of up to 20,000,000 shares of our common stock, $.0001 par value (or securities convertible into or exercisable for common stock) for up to an aggregate of $30,000,000 in gross proceeds, at a discount of up to 40% from the market price at the time of issuance. In addition, we are requesting stockholder approval to issue 75,000 shares of our restricted common stock to Dr. Moshe Talpaz pursuant to a consulting agreement between us and Dr. Talpaz.
   
Q:
Who is entitled to vote at the meeting?
   
A:
Stockholders of record at the close of business on April ___, 2006, the record date for the meeting, are entitled to receive notice of and to participate in the Meeting. As of that record date, we had outstanding and entitled to vote ______ shares of common stock. The common stock is the only class of our stock that is outstanding and entitled to vote at the Meeting. If you were a stockholder of record of common stock on that record date, you will be entitled to vote all of the shares that you held on that date at the meeting, or any postponements or adjournments of the meeting. Each outstanding share of our common stock will be entitled to one vote on each matter. Stockholders who own shares registered in different names or at different addresses will receive more than one Proxy card. You must sign and return each of the Proxy cards received to ensure that all of the shares owned by you are represented at the Meeting.
   
Q:
Who can attend the meeting?
   
A:
Only stockholders as of the record date, or their duly appointed proxies, may attend the meeting, and each may be accompanied by one guest. Seating, however, is limited. Admission to the meeting will be on a first-come, first-served basis. Registration will begin at 10 a.m., and seating will begin at 10:30 a.m. Cameras, recording devices and other electronic devices will not be permitted at the meeting.
   
Q:
Why are we soliciting proxies?
   
A:
Because many of our stockholders are unable to personally attend the Special Meeting, our Board of Directors (the "Board" or the "Board of Directors") solicits the enclosed proxy so that each stockholder is given an opportunity to vote. This proxy enables each stockholder to vote on the matters which are scheduled to come before the meeting. When the Proxy is returned properly executed, the stockholder's shares will be voted according to the stockholder's directions. Stockholders are urged to specify their choices by marking the appropriate boxes on the enclosed Proxy card.
   
Q:
What constitutes a quorum?
   
A:
The presence at the meeting, in person or by proxy, of the holders of a majority of the number of shares of common stock issued and on the record date will constitute a quorum permitting the meeting to conduct its business. As noted above, as of the record date, ______ shares of our common stock, representing the same number of votes, were outstanding. Thus, the presence of the holders of common stock representing at least ______ votes will be required to establish a quorum. If you submit a properly executed proxy card, even if you
 
3

 

 
abstain from voting or if you withhold your vote with respect to any proposal, you will be considered present for purposes of a quorum and for purposes of determining voting power present. Because abstentions and withheld votes are considered present for purposes of determining voting power, abstentions and withheld votes have the effect of a vote AGAINST a proposal. If a broker indicates on a proxy that it does not have discretionary authority as to certain shares to vote on a particular matter (“broker non-votes”), those shares will be considered present for purposes of a quorum but will not be considered present for purposes of determining voting power on that matter.
   
Q:
How do I vote?
   
A:
We are offering you four methods of voting.
 
 
·
You may indicate your vote on the enclosed proxy card, sign and date the card, and return the card in the enclosed prepaid envelope.

 
·
You may vote by telephone by calling the toll free number that appears on the enclosed proxy card and following the instructions given.

 
·
You may vote via the Internet by following the instructions provided on the enclosed proxy card.

 
·
You may attend the meeting and vote in person.

 
All shares entitled to vote and represented by a properly completed and executed proxy received before the meeting and not revoked will be voted at the meeting as you instruct in a proxy delivered before the meeting. If you do not indicate how your shares should be voted on a matter, the shares represented by your properly completed and executed proxy will be voted as the Board of Directors recommends on each of the enumerated proposals and with regard to any other matters that may be properly presented at the meeting and all matters incident to the conduct of the meeting. If you are a registered stockholder and attend the meeting, you may deliver your completed Proxy card in person. "Street name" stockholders who wish to vote at the meeting will need to obtain a proxy form from the institution that holds their shares. All votes will be tabulated by the inspector of election appointed for the meeting, who will separately tabulate affirmative and negative votes, abstentions and broker non-votes.
   
Q:
Can I vote by telephone or electronically?
   
A:
If you are a registered stockholder (that is, if you hold your stock in certificate form), you may vote by telephone, or electronically through the Internet, by following the instructions included with your Proxy card. If your shares are held in "street name," please check your Proxy card or contact your broker or nominee to determine whether you will be able to vote by telephone or electronically. Please follow the voting instructions on the enclosed proxy card.
   
 
The deadline for voting by telephone or electronically is 5:00 p.m. (Eastern Daylight Time) on May_____, 2006.
   
Q:
Can I change my vote after I return my Proxy card?
   
A:
A Proxy may be revoked by giving our Secretary written notice of revocation at any time before the voting of the shares represented by the Proxy. A stockholder who attends the meeting may revoke a Proxy at the meeting. Attendance at the meeting will not, by itself, revoke a Proxy.
   
Q:
What are the Board's recommendations?
   
A:
Unless you give other instructions on your Proxy card, the persons named as proxy holders on the Proxy card will vote in accordance with the recommendations of the Board of Directors. The Board's recommendation is set forth together with the description of each item in this Proxy Statement. In summary, the Board recommends a vote:

·
for the issuance of 75,000 shares of our restricted common stock, $.0001 par value, to Dr. Moshe Talpaz pursuant to a consulting agreement between us and Dr. Talpaz. (see page 6).
 
  With respect to any other matter that properly comes before the meeting, the proxy holders will vote as recommended by the Board of Directors or, if no recommendation is given, in their own discretion.
   
Q:
What vote is required to approve the matter to be voted upon at the special meeting?
   
A:
The potential issuance of up to 20,000,000 shares of our common stock, $.0001 par value (or securities convertible into or exercisable for common stock), at a price below fair market value may be approved by the vote of a majority of votes represented by shares present in person or by proxy and entitled to vote at the special meeting.

The issuance of 75,000 shares of our restricted common stock, $.0001 par value, to Dr. Moshe Talpaz pursuant to a consulting agreement between us and Dr. Talpaz may be approved by the vote of a majority of votes represented by shares present in person or by proxy and entitled to vote at the special meeting.
 
PROPOSAL NO. 1

THE POTENTIAL ISSUANCE AND SALE OF UP TO 20 MILLION SHARES OF OUR COMMON STOCK (OR SECURITIES CONVERTIBLE INTO OR EXERCISABLE OR EXCHANGEABLE FOR COMMON STOCK) FOR UP TO AN AGGREGATE OF $30 MILLION GROSS PROCEEDS, AT A DISCOUNT OF UP TO 40% OF THE MARKET PRICE AT THE TIME OF SALE WITHIN A MAXIMUM OF NINETY DAYS FROM THE DATE OF STOCKHOLDER APPROVAL

We are seeking our stockholders' approval, to the extent required by the American Stock Exchange ("AMEX"), to issue and sell up to an aggregate of 20,000,000 shares of our common stock, par value $.0001 (or securities convertible into or exercisable or exchangeable for common stock) for up to an aggregate of $30 million in gross proceeds at up to a 40% discount of the market price at the time of issuance and sale (including, if, at that time, the price is also below book value per share). Under Section 713 of the Listing Standards, Policies and Requirements of the AMEX, the sale, issuance, or potential issuance by a company of common stock (or securities convertible into common stock) equal to 20% or more of presently outstanding stock for less than the greater of book or market value of our stock requires stockholder approval, provided that stockholder approval is not required for a "public offering" as defined by the AMEX. As of April 5, 2006, we had 37,713,264 shares of our common stock outstanding.

Our operations have consumed substantial amounts of cash since inception. We expect to continue to spend substantial amounts to:

 
·
complete the clinical development of our two lead product candidates, Atiprimod for the treatment of multiple myeloma and advanced carcinoid cancer and L-Annamycin for the treatment of acute leukemia;
 
·
continue the development of our other product candidates;
 
·
finance our general and administrative expenses;
 
·
prepare regulatory approval applications and seek approvals for Atiprimod and L-Annamycin and our other product candidates;
 
·
license or acquire additional technologies;
 
·
launch and commercialize our product candidates, if any such product candidates receive regulatory approval; and
 
·
develop and implement sales, marketing and distribution capabilities.

In 2005, our cash used in operating activities increased significantly over 2004 and we expect that our cash used in operating activities will increase significantly for the next several years. For the year ended December 31, 2005, we used approximately $8,700,000, or approximately $725,000 per month in operating activities, as compared to approximately $4,700,000 and $2,000,000 for the years ended December 31, 2004 and 2003, respectively.

We intend to issue shares of our common stock (or securities convertible into or exercisable or exchangeable for commons stock) in connection with financing our plans to focus primarily on the development of two drugs to treat leukemia, multiple myeloma (an incurable blood cancer that invades and proliferates in bone marrow) and advanced carcinoid tumors. Our lead drug in development for leukemia, L-Annamycin, earlier completed a Phase I/IIa trial in relapsed or refractory acute leukemia patients. On December 1, 2005 we initiated a clinical trial in adult relapsed or refractory acute lymphocytic leukemia patients. Our second drug candidate, Atiprimod, is presently in a Phase I/IIa clinical trial in multiple myeloma patients, and in a Phase I/IIa clinical trial in advanced cancer patients. The drug is an orally available drug with antiproliferative and antiangiogenic activity. Additionally, our plan of research studies include further pre-clinical work on Guanilib, in preclinical development for gastrointestinal inflammation, a drug exploratory program focused on a class of anticancer compounds called Degrasyns, and a monoclonal antibody and vaccine candidate that are being explored as biodefense agents against staphylococcal and streptococcal bioterrorism agents.

We cannot be certain that funding will be available on acceptable terms, or at all. If we issue shares of our common stock (or securities convertible into or exercisable or exchangeable for shares of our common stock), this will have the effect of diluting our existing stockholders' ownership in our company. Further, depending upon the price at which shares might be issued, this may have the effect of depressing the price of shares of our common stock or diluting the book value of common stock per share or earnings (loss) per share. Additional issuances could also reduce the per share amounts available upon our liquidation, if that should occur.

The vote required to approve the issuance of our common stock as proposed is a majority of the shares present in person or by proxy and entitled to vote at the Special Meeting. If this proposal is not approved, any issuance requiring such approval will not be made, although further approvals may be sought. If the issuances are approved we do not intend to solicit the further approval of our stockholders for any issuance as to which the required approval remains in effect.

RECOMMENDATION OF THE BOARD OF DIRECTORS

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE FOR THE PROPOSAL TO AUTHORIZE, THE ISSUANCE AND SALE OF UP TO 20 MILLION SHARES OF OUR COMMON STOCK (OR SECURITIES CONVERTIBLE INTO OR EXERCISABLE OR EXCHANGEABLE FOR COMMON STOCK) FOR UP TO AN AGGREGATE OF $30 MILLION IN GROSS PROCEEDS, AT A DISCOUNT OF UP TO 40% OF THE MARKET PRICE AT THE TIME OF SALE WITHIN A MAXIMUM OF NINETY DAYS FROM THE DATE OF STOCKHOLDER APPROVAL. 
 
 
PROPOSAL NO. 2

ISSUANCE OF 75,000 SHARES OF OUR RESTRICTED COMMON STOCK, $.0001 PAR VALUE, TO DR. MOSHE TALPAZ

Under Section 711 of the Listing Standards, Policies and Requirements of the AMEX the establishment of an equity compensation arrangement pursuant to which stock may be acquired by consultants requires stockholder approval.

On January 31, 2006, we entered into a consulting agreement with Dr. Moshe Talpaz which is attached hereto as Exhibit A. We intend to use Dr. Talpaz as a consultant for our Degrasyn drug development program. Pursuant to the terms of the consulting agreement we agreed to issue 75,000 shares of our restricted common stock $.0001 par value to Dr. Talpaz. In addition, pursuant to the consulting agreement, we pay Dr. Talpaz $10,000 per year and we granted 575,000 options to Dr. Talpaz which are exercisable for our common stock at $1.60 per share. Such options vest based on milestones related to the Degrasyn program. The term of the consulting agreement is for the length of time we are developing the Degrasyns platform of compounds in all indications.

On January 10, 2006, we entered into a license agreement with the University of Texas M.D. Anderson Cancer Center whereby we were granted the exclusive right to manufacture, have manufactured, use, import, offer to sell and/or sell anti-cancer compounds called tyrphostins (renamed Degrasyns). Degrasyns are a second-generation class of tyrphostins developed by scientists at the University of Texas M.D. Anderson Cancer Center that have a novel anti-cancer mechanism-of-action that centers on their ability to selectively degrade key proteins that are involved in tumor cell proliferation and survival.

Dr. Talpaz is the chairman of our Scientific Advisory Board and currently is associated with the University of Michigan Comprehensive Cancer Center where he holds the titles of Professor, Internal Medicine, Associate Director, Translational Research and Associate Chief of Hematologic Malignancies. Dr. Talpaz was formerly the Professor of Medicine, David Burton, Jr. Endowed Chair at the M.D. Anderson Cancer Center, Houston, Texas. Dr. Talpaz was formerly Chairman of the Department of Bioimmunotherapy of the M.D. Anderson Cancer Center. Dr. Talpaz has been and continues to be involved in the clinical development of numerous cancer drugs and has been a pioneer in developing currently accepted treatment protocols especially in the leukemia area. Dr. Talpaz is a member of many committees such as the National Comprehensive Cancer Network Guidelines Panel and sits on several editorial and advisory boards, such as Hematology Digest, Bone Marrow Transplantation and Clinical Cancer Research. Dr. Talpaz discovered the use of interferon-a for treating chronic myeloid leukemia (CML) and he was the principal investigator until FDA approval. In addition, Dr. Talpaz has acted as a consultant to Hoffman LaRoche with regards to the FDA approval process for interferon.

We believe that retaining Dr. Talpaz as a consultant with respect to the development of the Degrasyns platform of compounds will be beneficial to our company in terms of accelerating the development of any drugs which derived from Degrasyns. The vote required to approve the issuance of our restricted common stock as proposed is a majority of the shares present in person or by proxy and entitled to vote at the Special Meeting.

RECOMMENDATION OF THE BOARD OF DIRECTORS

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE “FOR” THE ISSUANCE OF 75,000 SHARES OF OUR RESTRICTED COMMON STOCK, $.0001 PAR VALUE, TO DR. MOSHE TALPAZ PURSUANT TO A CONSULTING AGREEMENT BETWEEN THE COMPANY AND DR. TALPAZ
