AMAG Pharmaceuticals, Inc. Reports Financial Results for the Quarter Ended September 30, 2008.

LEXINGTON, Mass. -- AMAG Pharmaceuticals, Inc. (NASDAQ:AMAG), a biopharmaceutical company that utilizes its proprietary technology for the development and commercialization of a therapeutic iron compound to treat anemia and novel imaging agents to aid in the diagnosis of cancer and cardiovascular disease, today reported unaudited consolidated financial results for the quarter and nine months ended September 30, 2008.

As of September 30, 2008, the Company's cash, cash equivalents and investments totaled $241.1 million. Revenues for the quarter ended September 30, 2008 were $0.3 million as compared to revenues of $0.5 million for the same period in 2007. Revenues for the nine month period ended September 30, 2008 were $1.4 million as compared to $2.2 million for the same period in 2007.

Total operating costs and expenses for the quarter ended September 30, 2008 were $24.8 million as compared to $11.7 million for the same period in 2007, an increase of $13.1 million. Total operating costs and expenses for the nine month period ended September 30, 2008 were $57.8 million as compared to $31.0 million for the same period in 2007. The increase in operating costs and expenses for both the quarter and the nine month period ended September 30, 2008 was primarily due to increased research and development expenses to expand the Company's clinical development infrastructure and scale up the Company's manufacturing capabilities, and increased selling, general and administrative expenses to prepare for the planned commercialization of ferumoxytol.

The Company reported a net loss of $23.6 million, or $1.39 per basic and diluted share, for the quarter ended September 30, 2008, as compared to a net loss of $7.0 million, or $0.42 per basic and diluted share, for the same period in 2007. Net loss for the nine months ended September 30, 2008 was $49.9 million, or $2.94 per basic and diluted share, as compared to a net loss of $24.2 million, or $1.57 per basic and diluted share for the same period in 2007.

"We are working with the U.S. Food and Drug Administration (FDA) to address the Complete Response letter to our New Drug Application for ferumoxytol to treat iron deficiency anemia in chronic kidney disease patients. Concurrently, we are continuing our preparations for the planned U.S. commercial launch of ferumoxytol in the first quarter of 2009," commented Brian J.G. Pereira, President and Chief Executive Officer of AMAG Pharmaceuticals, Inc. "During the last quarter we made great progress in our transition to a commercial biopharmaceutical company. We are committed to bringing ferumoxytol to market," concluded Dr. Pereira.

Recent Corporate Highlights and Accomplishments

* Received a Complete Response letter from the FDA to the Company's New Drug Application for ferumoxytol for the treatment of iron deficiency anemia in chronic kidney disease patients, whether or not on dialysis. Three issues were raised in the FDA's response letter, which included a request for certain clinical information, observations made during a Good Clinical Practices (GCP) inspection at one of the Company's Phase III clinical sites, and observations noted during the pre-approval inspection of the Company's manufacturing facility. The Company is working with the FDA to address the Complete Response letter and believes that it will not need to conduct any additional clinical trials prior to approval.

* Initiated a Phase II study of ferumoxytol for vascular-enhanced magnetic resonance imaging (VE-MRI) in patients with peripheral arterial disease (PAD). The study will enroll approximately 100 patients with PAD, who will be randomized into one of three dose cohorts. Participants will undergo serial imaging with non-contrast magnetic resonance angiography, ferumoxytol VE-MRI, and digital subtraction angiography. In August 2008, the FDA granted Fast Track designation to ferumoxytol for its development as a diagnostic agent for VE-MRI to improve the assessment of peripheral arterial disease in patients with known or suspected chronic kidney disease.

* Completed hiring of nearly the entire ferumoxytol sales force, medical science liaison group and account management team. The planned sales force will include approximately 80 renal sales specialists and managers who will target over 5,000 nephrologists and hematologists in the U.S.
