December 7, 2015

SAN DIEGO, Dec. 7, 2015 (GLOBE NEWSWIRE) -- Neothetics, Inc. (NASDAQ:NEOT), a clinical-stage specialty pharmaceutical company developing therapeutics for the aesthetic market, today announced the issuance of U.S. Patent Number 9,198,885 by the United States Patent and Trademark Office (USPTO). This patent is directed to specific methods of using LIPO-202 and other agents for the reduction of fat accumulation and is the fourth issued patent directed to Neothetics' lead product candidate LIPO-202, the first non-invasive injectable drug candidate for reduction of central abdominal bulging due to subcutaneous fat in non-obese subjects.

George Mahaffey, Neothetics' president and chief executive officer, stated: "This patent further strengthens our robust intellectual property portfolio protecting our lead body contouring product candidate, LIPO-202."

About LIPO-202

LIPO-202 is an injectable formulation of salmeterol xinafoate, a well-known long-acting ß2-adrenergic receptor agonist used in several FDA-approved drugs, including ADVAIR® for asthma. Neothetics' studies suggest that salmeterol xinafoate also activates ß2-adrenergic receptors on fat cells, triggering the breakdown of triglycerides stored in the cells, causing them to shrink by means of a natural process called lipolysis. LIPO-202 is initially being developed as a non-surgical, convenient method to reduce non-obese individuals' central abdominal bulging due to subcutaneous fat – commonly characterized as a pot-belly, stomach rolls, or a pouch.
