ROCKVILLE, Md., Aug 3, 2011 (GlobeNewswire via COMTEX) --

Nabi Biopharmaceuticals (Nasdaq:NABI) today announced its second quarter financial results for the three month period ended June 25, 2011. The Company reported a net loss of $4.6 million, or $0.11 per share, compared to a net loss of $3.4 million, or $0.08 per share, for the period ended June 26, 2010.

Second quarter revenue was $3.7 million reflecting $3.2 million recognized from the initial payments received from GlaxoSmithKline Biologicals (GSK) associated with the PentaStaph(TM) sale and NicVAX(R) option and license agreements and $0.5 million for services provided to GSK under the PentaStaph and NicVAX agreements. Revenue for the second quarter 2010 was $4.8 million and included $3.9 million recognized from the initial PentaStaph and NicVAX payments and $0.9 million for services provided under the PentaStaph and NicVAX agreements.

Research and Development expenses were $6.5 million in the second quarter of 2011 compared to $6.5 million in 2010. Research and development expenses are expected to decline over the remainder of 2011 compared to 2010 levels. General and Administrative expenses were $1.4 million for the quarter ended June 25, 2011 compared to $1.2 million in the prior year period. General and administrative for the balance of 2011 will decrease slightly compared to 2010 levels.

For the six months ended June 25, 2011, the Company's net loss was $2.6 million, or $0.06 cents per share, compared to net income of $2.1 million, or $0.04 cents per share, for the six months ended June 26, 2010. Revenue of $12.9 million was recognized for the six months ended June 25, 2011 compared to $18.6 million for the comparable 2010 period. Research and development expenses were $11.8 million for the current six-month period compared to $12.4 million for the 2010 period while general and administrative expenses for the current six-month period were $2.8 million compared to $3.0 million in 2010.

Net cash used in operating activities was $9.0 million for the first six months of 2011 compared to net cash provided by operating activities of $40.4 million in the first six months of 2010. This change is primarily due to a reduction in the level of payments received from GSK associated with the PentaStaph and NicVAX agreements. Cash, cash equivalents and marketable securities totaled $102.3 million at June 25, 2011 compared to $110.7 million at the end of 2010. The decrease resulted from net cash used in operations.

The company did not repurchase any shares of common stock during the first half of 2011. Since inception of the stock repurchase plan in December 2007, we have repurchased a total of 19.9 million shares for a total of $87.2 million. A balance of $27.8 million remains available in the plan for future share repurchases.

      milestone which was achieved in the first quarter of 2011.
  --  In April 2011, the FDA approved Phoslyra, which is a new liquid

This data and the results of the second Phase III trial will help us determine the appropriate actions to take.
