Capstone Therapeutics Announces Loan From Existing Shareholder for Exclusive Due Diligence Period

TEMPE, Ariz., Dec. 15, 2015 (GLOBE NEWSWIRE) -- Capstone Therapeutics Corp. (OTCQB:CAPS) (“the Company”) and LipimetiX Development, Inc., the Company’s 60% owned joint venture (“JV”) announced today that the Biotechnology Value Fund, L.P. and other affiliates of BVF Partners L.P. ("BVF") have provided a $1 million secured loan to Company as consideration for the Company granting an exclusive period for due diligence, which may lead to an equity investment in Company of up to $10 million. For additional information, please see the Company’s Current Form 8-K filed with the Securities and Exchange Commission on December 15, 2015.

Chimeric Apolipoprotein E Mimetic Peptides

Apolipoprotein E (Apo E) is in a class of protein that occurs throughout the body. Apo E is essential for the normal metabolism of cholesterol and triglycerides. After a meal, the postprandial (or post-meal) lipid load is packaged in lipoproteins and secreted into the blood stream. Apo E targets cholesterol and triglyceride rich lipoproteins to specific receptors in the liver, decreasing the levels in the blood. Elevated plasma cholesterol and triglycerides are independent risk factors for atherosclerosis, the buildup of cholesterol rich lesions and plaques in the arteries. Atherosclerosis is the major cause of cardiovascular disease, peripheral artery disease and cerebral artery disease, and can cause heart attack, loss of limbs and stroke. Defective lipid metabolism also plays an important role in the development of adult onset diabetes mellitus (Type 2 diabetes), and diabetics are particularly vulnerable to atherosclerosis, heart and peripheral artery diseases.

The University of Alabama at Birmingham (“UAB”) scientists patented the first chimeric Apo E mimetic peptide in 1999, reducing the 299 amino acid native Apo E into a 28 amino acid, dual domain peptide that can be delivered therapeutically. One domain inserts into a lipoprotein surface and the second domain binds to the Apo E receptors in the liver. In 2010, our JV’s founding scientist, Dr. Dennis Goldberg, obtained worldwide right to patents for Apo E mimetic peptides from the UAB Research Foundation (“UABRF”). The JV has an Exclusive License Agreement with the University of Alabama at Birmingham Research Foundation for AEM-28 and its analogs.

AEM-28-02 was the first of the new generation chimeric Apo E peptides discovered, resulting in a provisional patent filing in July 2014. AEM-28-02 was found to be approximately 30% more potent (as tested in multiple animal models) than the parent molecule, AEM-28. AEM-28-14 is the most potent of the newly-discovered chimeric Apo E mimetic peptides. As shown in the attached figures, a single 50 ug injection of AEM-28-14 decreased cholesterol 98% in Apo E null mice. The rapid reduction of cholesterol was well tolerated, with no observed adverse effects. Cholesterol remained 35% below baseline at 24 hours.

Subject to continued favorable study results and funding availability, the JV may pursue regulatory approval of AEM-28-14 as treatment for Homozygous Familial Hypercholesterolemia, Acute Hypertriglyceridemic Pancreatitis and other orphan indications in hyperlipidemia. The JV may, in the future, possibly explore additional indications for its family of Apo E mimetic peptides including Acute Coronary Syndrome, Peripheral Artery Disease and other vascular diseases associated with Type 2 Diabetes and Metabolic Syndrome.
