Pacific Biomarkers Comments on Dramatic Benefits Reported for Experimental Cholesterol Drug Anacetrapib

Pacific Biomarkers today announced that it has noted a study on the experimental cholesterol drug anacetrapib

SEATTLE, WA, November 18, 2010 —Pacific Biomarkers, Inc. (OTCBB: PBMC), a provider of biomarker laboratory services to the pharmaceutical, biotechnology and diagnostics industries, today announced that it has noted, with great interest, a study on the experimental cholesterol drug anacetrapib that describes its ability to boost good cholesterol dramatically higher and drop bad cholesterol dramatically lower, soliciting hopes for an entirely new way of preventing heart attacks, strokes and deaths.

The anacetrapib study, led by Dr. Christopher Cannon of Brigham and Women’s Hospital in Boston on behalf of Merck & Co., was reported at a Chicago meeting of the American Heart Association. The drug works not by lowering LDL-C (“bad cholesterol”), as statins do, but by helping keep fat particles attached to HDL-C (“good cholesterol”), which carries them in the bloodstream to the liver for disposal.  A six-month study involving 1,623 people given the drug found LDL-C scores falling from 81 to 45 (versus 82 to 77 with placebo) and HDL-C rising from 41 to 101 (versus 40 to 46 with placebo), large changes that have not been seen before. Merck has announced a 30,000-patient study to determine whether these results will translate into better medical outcomes.

Commenting on these findings, Amar A. Sethi, MD, PhD, Vice President of Research and Development at PBI, said that therapy focused on increasing HDL-C is highly warranted. Currently available therapy, he said, relies on only one class of drugs which, although efficient at increasing HDL-C levels, have side effects preventing clinicians from increasing dosage and boosting HDL-C up to a significantly beneficial value.

“This safety study will have a huge impact on the future of this class of drugs,” Dr. Sethi said. “It is encouraging that the investigators have reported no changes in the test subjects’ blood pressure or aldosterone levels. The 36% reduction in LDL-C and 138% increase in HDL-C reported in the study is astounding, but is worth noting that complete remission of symptoms can’t be guaranteed, as the study was too small to clarify the drug’s exact role in reducing the cardiovascular event rate.”

Dr. Sethi added that a point of caution is whether the huge increase in HDL-C levels will translate into comparable definite protection against heart disease. Ever since the failure of a previous drug, torcetrapib, demand has surged for developing methods that can reliably assess the function of the HDL-C particle. Although the initial results from the anacetrapib trial suggest a trend toward overall protection, more research is required. Future studies of anacetrapib, said Dr. Sethi, will include analysis of the functional properties of the raised HDL-C.
