Lixivaptan BALANCE study is a 650-patient Phase III, global, multi-center, randomized, placebo-controlled, double-blind, study of lixivaptan for hyponatremia in patients with heart failure. The primary objective is to evaluate the safety and effectiveness of lixivaptan, when compared to the placebo, in increasing serum sodium from baseline in heart failure patients with hyponatremia. In previous studies, lixivaptan improved blood sodium levels, lowered body weight and increased urine volume. Those studies suggest that lixivaptan may play an important role in treating hyponatremia and the signs and symptoms of water retention associated with heart failure, Syndrome of Inappropriate Anti-Diuretic Hormone(SIADH), and Liver Cirrhosis with
Human serum albumin antigenic and represent many of the important neoantigens found in cooked or stored foods. They also interfere with the normal product of nitric oxide in cells. Although there are several lysine and arginine residues in the serum albumin structure, very few of them can take part in the glycation reaction. It is not clear exactly why only these residues are glycated in serum albumin, but it is suggested that non-covalent binding of glucose to serum albumin prior to the covalent bond formation might be the reason. The albumin is the predominant protein in most body fluids, its Cys34 represents the
