Ritter Pharmaceuticals Reports Second Quarter 2017 Financial Results and Provides Business Update

LOS ANGELES, CA-(Marketwired - Aug 7, 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 reported financial results for the second quarter ended June 30, 2017.

Recent Highlights

• Announced that the FDA has agreed to schedule an end-of-Phase 2 meeting with the Company that is expected to occur in the third quarter of 2017;
• Announced the issuance of three new patents, two in the U.S. and one in Australia, directed toward compositions containing and methods of using RP-G28;
• Entered into a common stock purchase agreement with Aspire Capital Fund to access up to $6.5 million through the sale of company stock;
• Reported additional analyses from the Company's Phase 2b/3 trial demonstrating significant reductions in lactose intolerance.

"Our activities at the Company have been very much focused on moving RP-G28 into Phase 3 clinical development," said Michael D. Step, Chief Executive Officer of Ritter Pharmaceuticals. "To that end, we have requested and have scheduled an End-of-Phase 2 meeting with the FDA to discuss the Phase 2b/3 clinical trial data and requirements for Phase 3 studies and NDA submission. We have also conducted further analysis of the results of our Phase 2b/3 clinical trial. Based on our analysis, we believe that the data supports RP-G28's potentially significant and durable real-world treatment effect for patients suffering from lactose intolerance. We look forward to our meeting with the FDA and moving RP-G28 toward regulatory approval."

Second Quarter 2017 Financial Results

For the second quarter of 2017, Ritter Pharmaceuticals reported a net loss attributable to common stockholders of approximately $2.0 million compared to a net loss of approximately $4.1 million for the second quarter of 2016. Basic and diluted net loss per share was $0.14 for the three months ended June 30, 2017 compared to basic and diluted net loss per share of $0.48 for the same period in 2016.

Research and development expenses for the second quarter of 2017 totaled approximately $774,000 compared to approximately $2.9 million for the second quarter of 2016. This decrease was due to the completion of the Phase 2b/3 clinical trial in the fourth quarter of 2016, with research and development expenses in the second quarter of 2017 mainly reflecting extension study fees and Phase 2b/3 analysis costs.

General and administrative expenses for the second quarter of 2017 were fairly consistent with the second quarter of 2016 at approximately $1.1 million and $1.2 million, respectively.

As of June 30, 2017, Ritter Pharmaceuticals had cash of approximately $5.4 million.
