Nabi Biopharmaceuticals Reports Third Quarter 2005 Results

BOCA RATON, Fla., Oct. 19 /PRNewswire-FirstCall/ -- Nabi Biopharmaceuticals reported today that revenues from PhosLo(R) (calcium acetate) in the third quarter exceeded levels reported in the first two quarters of 2005 combined. Patient demand has remained strong despite intense competitive activity. Reported PhosLo revenues totaled $8.1 million and correlate to patient usage during the third quarter. Importantly, the cash margin earned on these improved revenues helped to fund an increasing investment in support of the anticipated commercial launch of StaphVAX(R) [Staphylococcus aureus Polysaccharide Conjugate Vaccine] in 2006. Also today, the company reported that it has continued to make significant progress toward its four main goals for the remainder of 2005: report top-line results from the StaphVAX confirmatory Phase III clinical trial; file its Biologics License Application (BLA) for StaphVAX in the U.S. by the end of 2005; support the review and approval of the StaphVAX license application in Europe; and complete studies to support the broader clinical application of StaphVAX. In total, cash and marketable securities decreased $20 million during the quarter in support of the company’s investment in these activities. At the end of the third quarter, cash and marketable securities totaled $136.5 million.

In line with its strategy to develop and commercialize a comprehensive healthcare-associated infections franchise, Nabi Biopharmaceuticals has recently achieved several important milestones. The company announced positive results from its consistency lots study evaluating the quality of three lots of StaphVAX manufactured at commercial scale. This provided important evidence that a reliable supply of the vaccine can be manufactured by the company’s contract manufacturing partner to support its initial launch in Europe and in the U.S. In addition, results from a safety and immunogenicity study in orthopedic surgery patients, when combined with earlier data from a clinical study in cardiac surgery patients, adds to the clinical evidence that StaphVAX could confer benefit in protecting broader patient populations from life threatening S. aureus infections. The company also initiated a long-term dosing study designed to evaluate the use of StaphVAX to provide protection well beyond one year in patients who are at chronic risk for S. aureus infections. This study is important in realizing the company’s strategic goal to commercialize a comprehensive solution to S. aureus infections through better short- and long-term outcomes for patients, thereby reducing the overall cost of care. Finally, Nabi Biopharmaceuticals initiated the first human clinical study for its vaccine being developed to prevent S. aureus type 336 infections. When combined with the current formulation of StaphVAX, this vaccine should allow Nabi Biopharmaceuticals to provide an approach to prevent essentially all clinically relevant S. aureus infections.

The company also continued to make progress with European regulators toward the approval of its Marketing Authorization Application (MAA) for the use of StaphVAX to prevent S. aureus infections in end-stage renal disease (ESRD) patients on hemodialysis. In support of an expected launch of StaphVAX in the UK, Ireland and Germany in 2006, the company appointed Edwin Klumper, M.D., as vice president of sales and marketing for Europe and Chris Tovey as country manager in the UK and Ireland, and is hiring additional personnel. In addition, Nabi Biopharmaceuticals continued to build relationships with key opinion leaders across Europe and with partners who have experience in medical education, reimbursement, and healthcare-associated infections. As a result of these efforts, the company believes that the commercial opportunity for StaphVAX in Europe aligns well with the recognition of the need for a preventative approach shared by key opinion leaders and public health officials.

“Our significant accomplishments in 2005 have brought us much closer to achieving our goal to file our BLA and commercialize StaphVAX in Europe and the United States,” stated Thomas H. McLain, chairman, chief executive officer and president. “Hospital-acquired infections are the fourth leading cause of death in the United States today, according to the United States Centers for Disease Control and Prevention. We believe our focus on developing treatments to prevent these infections positions us in an important leadership role in solving this serious and unmet medical need. These efforts have clearly defined that our focus in this area is unique and that our infectious disease franchise can provide a solution to the global burden of healthcare-associated infections -- both from a public health perspective and an economic one.”

“True to our core business strategy, we have also remained focused on advancing our base business,” continued Mr. McLain. “Refocused sales and marketing efforts emphasizing PhosLo’s proven efficacy and economic advantages, as well as its safety profile, have resulted in a positive prescription response and lower wholesale inventory levels. In addition, we recently introduced our Share Program, which provides PhosLo to ESRD patients who do not have health insurance. In just two months, almost 3,000 additional patients are now taking this important therapy. We also remain committed to our approach to provide solid clinical data from well-designed clinical studies to support the advantages of our products. Towards that end, we just completed the enrollment of the CARE2 study, a full three months ahead of schedule. This study is expected to provide important clinical data in 2005 and 2006 in support of PhosLo’s efficacy, safety and value.”

Review of Operations

Sales of PhosLo were $8.1 million in the third quarter of 2005 compared to $9.2 million in the third quarter of 2004 and $7.0 million in the first two quarters of 2005 combined. Continued strong patient utilization of PhosLo in the third quarter of 2005 exceeded shipments to wholesalers resulting in reduced wholesaler inventory levels of PhosLo. As a result of reduced inventory levels, the company reversed the deferral of $5.2 million of revenue recorded in the second quarter when wholesaler inventories were higher. That reversal is included in reported revenue in the third quarter. Also, the conversion of patients to the gelcap formulation of PhosLo was virtually completed in the third quarter with less than one month’s supply of PhosLo tablets on hand at wholesaler locations.

Sales of Nabi-HB(R) [Hepatitis B Immune Globulin (Human)] totaled $10.8 million in the third quarter of 2005 as compared to sales of $13.7 million in the comparable quarter in 2004. The decrease in Nabi-HB sales from third quarter 2004 levels is consistent with a reported decrease in the number of HBV-positive liver transplant surgeries in 2005. Increasing use of Nabi-HB for patients undergoing maintenance therapy following liver transplant partially offset this trend. For the first nine months of 2005, overall patient use of the product as reported on internal tracking data is consistent with reported revenues.

Sales of the company’s other biopharmaceutical products were $1.3 million in the third quarter of 2005, compared to $2.1 million in the third quarter of 2004. Results in the 2005 period reflect lower sales of Aloprim(TM) [Allopurinol sodium for injection], due to the introduction of a competitive product in the second half of 2004, offset by increased contract manufacturing revenue.

Sales of antibody products were $10.6 million in the quarter, compared to $11.0 million in the corresponding quarter of 2004. This is a result of slightly increased production of non-specific plasma and lower sales of specialty plasmas as the company retained anti-HBs plasma for future production of Nabi-HB, consistent with its strategy for this segment of its operations. Also during the quarter, the company allocated some of its plasma production capacity to produce anti-S. aureus plasma in preparation for the manufacture of Altastaph(TM) [Staphylococcus aureus Immune Globulin Intravenous (Human)] for use in future clinical trials.

Research and development expenses totaled $17.4 million in the quarter compared to $17.7 million in the third quarter of 2004 and $18.6 million in the second quarter of 2005. These expenses were driven primarily by the costs associated with advancing the StaphVAX clinical program, including completion of the StaphVAX confirmatory Phase III clinical trial, ongoing development of StaphVAX manufacturing capacity and the preparation for filing the StaphVAX BLA, which is expected by the end of 2005. Research and development expenses also included costs related to clinical trials of next generation Gram- positive infections programs, preparatory steps for future clinical trials of Altastaph and clinical programs supporting PhosLo.

In line with company-established expectations, selling, general and administrative expenses increased to $19.6 million due to activities related to the future commercialization of StaphVAX. This included ongoing market and pricing research, establishing commercial operations in Europe and pre-launch marketing activities.

Other operating expenses were $2.3 million for the quarter, comparable to 2004 same quarter totals. These expenses primarily reflect amortization of the intangible assets associated with the acquisition of PhosLo.

As a result of the above factors, the company reported a net loss of $16.1 million, or $0.27 per share for the third quarter compared to a net loss of $10.9 million or $0.18 per share in the comparable quarter of 2004.

Additional Outlook for 2005

Following the reduction of wholesaler customer inventory levels of PhosLo, partially offset by the impact of a previously announced price increase, the company now projects that full year sales of PhosLo will be in the range of $26 million to $28 million. Considering the decrease in liver transplants, offset by the increased use of Nabi-HB in maintenance therapy post transplant, the company projects that Nabi-HB sales will be at least equal to 2004 sales of $40 million. For full year 2005, biopharmaceutical revenues are now expected to be in the range of $75 million to $79 million. Total revenues are expected to be between $120 million and $125 million. Expectations for research and development expense to increase up to 20% from last year are unchanged. Related to accelerating preparations for the launch of StaphVAX in Europe and the U.S. as well as expected increased sales and marketing, the company now expects selling, general and administrative expenses to increase approximately 20% from 2004 levels.
