11 March 2014. An intermediate-stage clinical trial by La Jolla Pharmaceutical Company<\/a> in San Diego shows patients with chronic kidney disease taking the company’s drug candidate\u00a0succeeded in improving their kidney functions, compared to similar patients taking a placebo. However, the drug code-named\u00a0GCS-100 appears effective only in lower rather than higher doses. The findings are scheduled for presentation at a Roth investment conference<\/a> this week in Dana Point, California.<\/p>\n

Chronic kidney disease<\/a> is a condition caused mainly by diabetes and high blood pressure,\u00a0where kidneys lose their ability to function normally, with complications such as anemia, bone weakness, and nerve damage. The condition also increases the risk of heart or blood vessel disease, and can lead to kidney failure. National Kidney Foundation says some 26 million American adults have chronic kidney disease.<\/p>\n

GCS-100<\/a> is a complex carbohydrate compound derived from pectin, a naturally-occurring fiber found in citrus fruit pulp and skin. The compound, administered as an intravenous injection, binds and sequesters\u00a0galectin-3<\/a>, a protein which in excess amounts is associated with various degenerative processes in the body, including cancer, tissue fibrosis, \u00a0and organ failure.<\/p>\n

The clinical trial<\/a> tested GCS-100 in two doses — 1.5 milligrams or 30 milligrams per square meter — against a placebo, among 121 patients with chronic kidney disease in the U.S. at four locations. Patients received the drug or placebo once a week for eight weeks.<\/p>\n

The trial look primarily for changes in\u00a0estimated glomerular filtration rate<\/a>, a test of kidney function; glomeruli are tiny filters in kidneys that remove waste from the blood. The study also measured any effects of the drug on the amount of\u00a0galectin-3 circulating in the body, as well as the drug’s safety and tolerability.<\/p>\n

La Jolla says patients taking GCS-100 at the lower concentration,\u00a01.5 milligrams per square meter, reported higher\u00a0estimated glomerular filtration rates compared to the placebo, between the start and end of treatments. Patients receiving the lower dose also had lower levels of circulating\u00a0galectin-3. Differences between patients taking GCS-100 at the higher dose or the placebo were not large enough to be statistically reliable, either for\u00a0glomerular filtration rates or levels of\u00a0galectin-3.<\/p>\n

The company says GCS-100 was well tolerated. Of the 121 patients, 117 completed the trial. Two serious adverse events were reported, but not specified, among patients taking GCS-100 at the higher dose, which La Jolla says were not related to the drug. No adverse effects were reported among patients taking the drug at the lower dose.<\/p>\n
