Momenta Pharmaceuticals Reports Financial Results for the Third Quarter of 2008

CAMBRIDGE, Mass., Nov 3, 2008 (GlobeNewswire via COMTEX News Network) -- Momenta Pharmaceuticals, Inc. (Nasdaq:MNTA), a biotechnology company specializing in the detailed structural analysis of complex mixture drugs, today announced its financial results for the third quarter and nine months ended September 30, 2008.

For the third quarter of 2008, the Company reported a net loss of $16.0 million, compared with a net loss of $18.9 million for the same period in 2007. For the nine months ended September 30, 2008, the Company reported a net loss of $44.3 million compared with a net loss of $54.6 million in the same period in 2007. At September 30, 2008, the Company held cash, cash equivalents, and marketable securities of $95.4 million, compared with $135.9 million at December 31, 2007.

"The commercialization and launch of M-Enoxaparin remains our highest priority, and during the third quarter we made significant progress towards that goal," said Craig A. Wheeler, President and Chief Executive Officer. "On September 26, our collaborative partner Sandoz submitted an amendment to the M-Enoxaparin ANDA that we believe to be a complete response to the FDA addressing the potential for immunogenicity of the drug product. In addition, a final mandate was issued following the re-affirmation by the U.S. Court of Appeals rendering the Lovenox(r) Orange Book patents unenforceable."

Highlights of the Quarter:



 * On September 26th, we issued an 8-K disclosing that Sandoz had
   submitted an amendment to the FDA that we believe fully addresses
   the agency's questions concerning the immunogenic potential of
   M-Enoxaparin.
 * On September 25th, the U.S. District Court of Appeals denied Sanofi
   Aventis's petition for rehearing in the Lovenox patent dispute.  A
   final mandate was issued on October 2nd, officially rendering the
   Orange Book patents unenforceable and triggering the start of the
   180-day marketing exclusivity period for the first-to-file
   applicant.
 * In August, Teva filed a patent infringement suit against Sandoz and
   Momenta in response to the ANDA submission for generic Copaxone.
 * In July, we presented Phase 1 data demonstrating the potential of
   M118 as an anticoagulant therapy in acute coronary syndrome at the
   IXth World Conference on Clinical Pharmacology and Therapeutics
   Meeting in Quebec City, Canada.

Revenue for the third quarter of 2008 was $3.9 million, compared to $5.1 million for the third quarter of 2007. For each of the nine months ended September 30, 2008 and 2007, revenue totaled $11.6 million. The revenue in both periods consisted of revenue earned from Sandoz, an affiliate of Novartis. The decrease in revenue from the third quarter of 2007 compared to the third quarter of 2008 was due to the timing of development expenditures reimbursable under the Company's collaborations with Sandoz.

Research and development expenses for the third quarter of 2008 were $14.1 million, compared to $19.5 million for the same period in 2007. For the nine months ended September 30, 2008, research and development expenses were $39.9 million, compared to $50.3 million in the comparable period in 2007. The decreases in research and development expenses were primarily due to decreases in manufacturing and process development costs and research conducted by third parties in support of our M356, M-Enoxaparin and M118 programs.

For each of the three months ended September 30, 2008 and 2007, general and administrative expenses totaled $6.3 million. For the nine months ended September 30, 2008, general and administrative expenses were $18.4 million, compared to $22.0 million in the same period of 2007. The decrease in general and administrative expenses for the nine months ended September 30, 2008 compared to the same period in 2007 was primarily due to a decrease in stock-based compensation expense and a reduction in professional fees and other legal expenses.
