Neothetics Announces Reaffirmation of Patents and Termination of Reexamination Challenge by United States Patent and Trademark Office

SAN DIEGO, Aug. 6, 2015 (GLOBE NEWSWIRE) -- Neothetics, Inc. (Nasdaq:NEOT), a clinical-stage specialty pharmaceutical company developing therapeutics for the aesthetic market, today announced the reaffirmation of all claims of two of its issued patents by the United States Patent and Trademark Office (USPTO) and termination of the reexamination challenges that were initiated by a third party. Both patents are directed to methods of treatment for Neothetics' lead asset, 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: "We are pleased to have received notice from the USPTO that it has concluded its reexamination proceedings related to two of our issued patents and the result is in our favor. We are encouraged that the emergence of patents from the reexamination process typically results in a strengthening of assets by reducing the likelihood of a future finding of invalidity or unenforceability based upon a prior art assertion. We are confident that we have a robust intellectual property portfolio protecting our lead body contouring product candidate, LIPO-202, which is currently in pivotal Phase 3 trials."

These proceedings began in September 2014, when a law firm representing one or more unidentified third parties filed two separate Requests for Ex Parte Reexamination with the USPTO against all claims of U.S. Patent No. 8,420,625, or the '625 patent, and all claims of Neothetics' U.S. Patent No. 8,404,750, or the '750 patent. The USPTO granted each request for reexamination and later issued office communications with respect to each patent. Neothetics responded to both communications, and on July 31, 2015, the USPTO issued notices confirming the patentability of all claims of both the '625 and '750 patents and terminated both reexamination proceedings.

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 being developed as a non-surgical, convenient method to reduce non-obese individuals' central abdominal bulging due to subcutaneous fat – commonly referred to as a pot-belly, stomach rolls, or a pouch.
