Nabi Biopharmaceuticals Announces Positive Results From PhosLo(R) EPICK Study

Study of Stage 4 Kidney Disease Patients Achieves Both Primary and Secondary Endpoints

BOCA RATON, Fla., Oct. 16 (HSMN NewsFeed) -- Nabi Biopharmaceuticals (Nasdaq: NABI ) today announced positive results from the PhosLo® (calcium acetate) EPICK study in Chronic Kidney Disease (CKD) patients suffering from Stage 4 kidney disease. The findings were presented on October 13, 2006 in poster format at the International Society of Nephrology (ISN) Symposium in Copenhagen, Denmark.

The EPICK study was designed to demonstrate that PhosLo is effective and safe in controlling hyperphosphatemia in Stage 4 CKD patients without causing very low calcium levels (hypocalcemia), or high levels of acidity in the blood (metabolic acidosis). The study achieved its primary endpoint of superior serum phosphorus control versus placebo with a P-value equal to 0.0003. The study also achieved its secondary endpoints by demonstrating that attaining a parathyroid level (PTH) target of 70 - 110 pg/mL is more likely with PhosLo than with placebo and by showing that attaining a calcium phosphorus product (CA x P) of 23 - 43 mg2/dL2 is more likely with PhosLo than with placebo.

PhosLo is a prescription phosphate binder currently indicated for the control of elevated phosphorous levels (hyperphosphatemia) in patients with end-stage renal (kidney) disease (ESRD). The positive EPICK study results will support license applications in the United States and European Union and are expected to be filed during 2006. These license applications will seek approval for the broader use of PhosLo in pre-dialysis patients. If successful, PhosLo would be the only phosphate binder on the US market that has a labeled indication for Stage 4 CKD patients.

Henrik S. Rasmussen, M.D., Ph.D., senior vice president, clinical, medical and regulatory affairs, Nabi Biopharmaceuticals, stated, "These results support the role of PhosLo in controlling hyperphosphatemia in Stage 4 CKD patients, a serious problem among this growing patient population. We are pleased to have delivered on our goals of completing this study on schedule and achieving both the primary and secondary endpoints."

On October 12, 2006, Nabi Biopharmaceuticals announced that it had entered into an agreement to sell PhosLo and related assets to Fresenius Medical Care. This transaction is expected to close within thirty days.

About PhosLo

PhosLo is administered orally, and when given with food, it combines with dietary phosphate to form insoluble calcium phosphate complexes that are eliminated from the body, thereby reducing phosphorus absorption, helping to prevent excess blood phosphorus levels. Patients should have serum calcium levels closely monitored and their dose of PhosLo adjusted or terminated to bring levels to normal. PhosLo is contraindicated in patients with hypercalcemia. No other calcium supplements should be given concurrently with PhosLo. PhosLo is well tolerated. Nausea, hypercalcemia, and pruritus (itching) have occasionally been reported during PhosLo therapy.
