FOR IMMEDIATE RELEASE

 

Nabi Biopharmaceuticals Announces Results of StaphVAX®

Confirmatory Phase III Clinical Trial

 

— Study Failed to Show that StaphVAX Prevents S. aureus Infections in Kidney Disease Patients —

 

— Company to Increase Focus on Other Pipeline Products —

 

Rockville, Maryland, November 1, 2005—Nabi Biopharmaceuticals (Nasdaq: NABI) today announced that StaphVAX® [Staphylococcus aureus Polysaccharide Conjugate Vaccine] failed to meet its primary endpoint in the company’s confirmatory Phase III clinical trial.

 

The study, a randomized, double-blinded, placebo-controlled trial of 3,600 patients on hemodialysis, found no reduction in S. aureus types 5 and 8 infections in the StaphVAX group as compared to the placebo group. The company will immediately initiate an assessment to determine the factors causing this outcome, including the vaccine target (S. aureus polysaccharide capsule) and the quality of the antibody generated by the vaccine. Results will be available within the next few months. It is important to note, however, that StaphVAX was highly immunogenic, confirming that Nabi Biopharmaceuticals’ vaccine conjugation technology is effective in producing and sustaining high levels of specific antibodies.

 

Thomas H. McLain, chairman, president and chief executive officer, Nabi Biopharmaceuticals, stated, “We are obviously surprised and very disappointed with the results of the StaphVAX confirmatory Phase III trial. While we complete our assessment over the next few months, we will re-focus our capabilities in developing vaccine and antibody products in other areas of significant medical need. This includes advancing other bacterial vaccines in development; NicVAX, a vaccine for smoking cessation; and Civacir™, an antibody product for the prevention of hepatitis C post-liver transplant. At the end of the third quarter, we had cash and marketable securities totaling $137 million and we will continue to generate cash margins earned on product sales. This assures our ability to accelerate the development of these programs, which are closely aligned with our business strategy and core competencies.”

 

Next Steps

 

While the company completes its assessment of the Phase III trial results, it will halt further development of StaphVAX and will withdraw its Marketing Authorization Application (MAA) to market StaphVAX in the European Union.

 

The company will also halt the development of Altastaph [Staphylococcus aureus Immune Globulin Intravenous (Human)], its investigational product for the prevention and treatment of S. aureus infections, as it is based on the same capsular polysaccharide technology as StaphVAX.

The significant majority of the company’s development spending in 2005 has been directed toward pre-launch and clinical activities for StaphVAX and Altastaph. Spending on these activities will stop during the fourth quarter of 2005.

 

In addition, the company expects to advance the development of its other vaccine programs, including: NicVAX (Nicotine Conjugate Vaccine), which is currently in Phase IIb clinical trials; its non-capsular polysaccharide-based vaccine for S. aureus (type 336) in Phase I clinical trials; its S. epidermidis vaccine in Phase I clinical trials; and, its community-acquired S. aureus program (PVL) and Enterococcal vaccine in pre-clinical development.

 

The company also plans to advance the clinical development of its antibody product, Civacir [Hepatitis C Immune Globulin (Human)] for the prevention of hepatitis C after liver transplant.

 

About NicVAX

NicVAX is Nabi Biopharmaceuticals’ novel, innovative and proprietary investigational vaccine being developed to treat nicotine addiction and prevent smoking relapse. The company was recently awarded a $4.1 million grant by the U.S. National Institute on Drug Abuse (NIDA), part of the National Institutes of Health, for partial funding of the company’s development program for NicVAX.

 

By the end of 2005, Nabi Biopharmaceuticals intends to announce preliminary safety and immunogenicity results from a Phase IIb clinical study in Europe. These results will define the next clinical development steps for NicVAX. The company will manufacture NicVAX in its own vaccine facility in Boca Raton, Florida.

 

About Civacir

Civacir is an investigational human polyclonal antibody product that contains antibodies to the hepatitis C virus (HCV). Civacir is being developed for the prevention of hepatitis C after liver transplant.

 

The National Institutes of Health (NIH) has funded and conducted a Phase I/II clinical trial of Civacir in HCV-positive liver transplant patients at four study sites in the U.S. This randomized, controlled study evaluated the safety of dosing patients with Civacir during and after transplant surgery, the level of HCV-specific antibodies in trial subjects following dosing, liver enzyme levels (a measure of liver damage) and HCV levels in the transplanted livers.
