Ritter Pharmaceuticals Announces Issuance of New Patents for its Lactose Intolerance Treatment, RP-G28, and Provides an Update on its Path Forward into Phase 3

LOS ANGELES (May 2, 2017) – Ritter Pharmaceuticals, Inc. (NASDAQ: RTTR) (“Ritter Pharmaceuticals” or the “Company”), a leading developer of novel therapeutic products that modulate the human gut microbiome to treat gastrointestinal diseases, today announced that it has been issued three new patents directed to its development compound RP-G28.  The Company is also providing an update on its phase 3 program based on conversations with regulatory authorities and experts.

The Company has been issued two new U.S. patents and one new Australian patent.  The two new U.S. patents (U.S. Patent Nos. 9,579,340 and 9,592,248) are directed to compositions containing RP-G28 and methods of using RP-G28, further strengthening the intellectual property positions of RP-G28.  The issuance of an Australian patent (No. 20102184) provides additional international protection for compositions containing the compound.

“We are pleased to add these additional issued patents to our portfolio of issued and pending claims, providing both validation and protection for our compound, RP-G28, in development for the treatment of lactose intolerance” stated Michael Step, CEO of Ritter Pharmaceuticals.  “We now have 15 issued patents and over 25 additional pending patent applications.  This additional intellectual property continues to protect our compound and its uses, likely beyond 2030.”

In addition to the new intellectual property, the company has been working diligently on preparing for phase 3, having had preliminary discussions with its regulatory experts and the U.S. Food and Drug Administration (FDA).  “We will be holding an end of phase 2 meeting with the FDA to present and discuss our phase 3 plan, for which we hope to receive guidance and agreement on what is expected before filing a new drug application (NDA) for commercializing RP-G28,” said Andrew Ritter, President and co-founder of Ritter Pharmaceuticals.  “We believe that the completion of one well-powered phase 3 study with robust clinical results may be sufficient to successfully file this NDA.  Based on our communication with the FDA, including our Type C meeting in March 2017 and subsequent communications, we feel we have established agreement with the FDA on defining clinically meaningful benefit to patients and have established endpoints that we feel are both achievable in the clinic and represent sufficient basis for an approval once completed.  We will be discussing the final features of this trial and other relevant aspects of the program with the FDA at our upcoming meeting to ensure we have a product that meets regulatory goals in phase 3,” stated Andrew Ritter.
