Item 4.                      Purpose of Transaction
 
The Filers acquired the Stock for investment purposes and had previously reported their ownership of the Stock of the Issuer on Schedule 13G.  The Filers have determined to convert the reporting of their ownership of the Stock of the Issuer to a filing on Schedule 13D in order to obtain flexibility to express their views and to take actions with respect to the Issuer, its business, the Stock and the directors and officers of the Issuer.  On November 22, 2010, PAI LLC issued a press release (the “Press Release”), which stated that PAI LLC was calling on the board of directors of the Issuer to, among other things, use excess cash to repurchase outstanding shares and to otherwise increase stockholder value, and which included the text of a letter that PAI LLC sent to the Issuer, dated as of November 22, 2010 (the “Letter”) that describes the potential for several proactive measures concerning the Issuer, including without limitation using excess cash to effect a stock repurchase, and the Filers intend to engage in discussions with the Issuer concerning the foregoing.  A copy of the Press Release (including the Letter) is attached as Exhibit B hereto.  References to and the descriptions of the Press Release and the Letter as set forth above in this Item 4 are qualified in their entirety by reference to the copies of the Press Release and the Letter which are included as Exhibit B to this Statement, and which are incorporated by reference in this Item 4 in their entirety where such references and descriptions appear.  Depending on various factors, the Filers could determine to take one or more, or to support one or more, of the actions described in the next paragraph, including without limitation one or more of the actions described in paragraphs (a) through (j) of Item 4 of Schedule 13D.

In pursuing their investment purposes, the Filers may from time to time further purchase, hold, vote, trade, dispose of, engage in option, swap or other derivative securities transactions with respect to or otherwise deal in the Stock at times, and in such manner, as they deem advisable to benefit from changes in the Stock’s market price, changes in the Issuer’s operations, business strategy or prospects, or from the sale or merger of the Issuer. To evaluate such alternatives, the Filers routinely will monitor the Issuer’s operations, prospects, business development, management, competitive and strategic matters, capital structure and prevailing market conditions, as well as alternative investment opportunities, the Filers’ liquidity requirements and other investment considerations. Consistent with their investment research methods and evaluation criteria, the Filers may discuss such matters with the Issuer’s management, Board of Directors, other shareholders, industry analysts, existing or potential strategic partners or competitors, investment and financing professionals, sources of credit and other investors. Such factors and discussions may affect materially, and result in, the Filers’ modifying their ownership of the Stock, exchanging information with the Issuer pursuant to appropriate confidentiality or similar agreements, proposing changes in the Issuer’s operations, governance or capitalization, or in proposing or taking one or more of the actions described in paragraphs (a) through (j) of Item 4 of Schedule 13D.  Except as described herein, the Filers have no present plan or proposal that would include any of the actions described in paragraphs (a) through (j) of Item 4 of Schedule 13D.  The Filers may reconsider and change their plans or proposals relating to the Stock at any time.

Item 5.                      Interest in Securities of the Issuer
 
(a), (b), (d) Each Filer’s beneficial ownership of the Stock on the date of this report is reflected on that Filer’s cover page.  PAI LLC is an investment adviser with the power to invest in, vote and dispose of the Stock on behalf of its clients.  Its clients have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the Stock.  No individual client holds more than 5% of the outstanding Stock.  Mr. Edwards is the controlling shareholder of PAI Corp, which is the sole manager of PAI LLC, and is the controlling owner of PAI LLC.  Dr. Yun is the president of PAI Corp and PAI LLC.  The Filers are filing this Schedule 13D jointly, but not as members of a group, and each of them expressly disclaims membership in a group.  Each Filer disclaims beneficial ownership of the Stock except to the extent of that Filer’s pecuniary interest therein.
 
(c)           Listed below are all the transactions in the Stock by the Filers during the last 60 days.  The purchases and sales were effected in open market transactions, and the price per share includes commissions paid.   There were no other transactions in the Stock by the Filers during such period.

PRESS RELEASE (INCLUDING THE LETTER)

[Letterhead of Palo Alto Investors]

FOR IMMEDIATE RELEASE

Palo Alto Investors Calls on Board of AMAG Pharmaceuticals
to Use Excess Cash to Repurchase Stock and
Increase Stockholder Value
 
 
Palo Alto Investors Believes Repurchase is in Best Interest of Stockholders

Palo Alto, Calif. (November 22, 2010) – Palo Alto Investors, LLC (“Palo Alto Investors”), the owner, together with its affiliates, of 9.3% of the outstanding shares of common stock of AMAG Pharmaceuticals, Inc. (NASDAQ: AMAG)(“AMAG” or the “Company”) announced today that it had delivered a letter to AMAG’s board of directors expressing its concern with AMAG’s recent stock performance, and urging the Company to use its excess cash to repurchase stock and otherwise increase stockholder value.
 
The text of the letter from Palo Alto Investors to the board of directors of AMAG follows:
 
November 22, 2010
 
Board of Directors
 
AMAG Pharmaceuticals, Inc.
 
100 Hayden Avenue
 
Lexington, MA  02421
 
Members of the Board:
 
As you know, Palo Alto Investors, LLC (“Palo Alto Investors”), together with its affiliates, is one of the largest stockholders of AMAG Pharmaceuticals, Inc. ("AMAG" or the "Company"), holding an ownership stake of approximately 9.3% of the Company’s outstanding common stock.
 
We are writing to express our concern with the poor performance of Company’s stock, particularly in light of the recent FDA approval of its drug Feraheme® and the Company’s overall long-term prospects.  Despite this promise, AMAG's stock price has fallen more than 60% year-to-date and presently trades near its cash value (including cash equivalents and short-term investments) of $273 million (as reported in the Company’s Form 10-Q for the quarterly period ended September 30, 2010).
 
Palo Alto Investors believes that the Company is extremely undervalued, that Feraheme® is the most effective way to administer IV iron, and that AMAG has the potential to grow revenues substantially from current levels.  We further believe that AMAG will have abundant excess cash upon reaching profitability, and that it can maximize stockholder value by using this excess cash to repurchase its common stock at these severely depressed levels.
 
Palo Alto Investors endeavours to be a long-term partner, and we would like to work collaboratively with AMAG to maximize stockholder value.  While increasing stockholder value and acting in the best interests of stockholders is always the principal duty of all members of the board of directors, it is particularly important in the current fiscal environment.
 
Palo Alto Investors is available to discuss these matters in greater detail with the management and board of directors of AMAG.  We await your response.
 

 
Sincerely,
 

 
Palo Alto Investors, LLC
