Ritter Pharmaceuticals Reports Top-Line Results from its Liberatus Phase 3 Trial of RP-G28 for Lactose Intolerance

/EIN News/ -- LOS ANGELES, Sept. 12, 2019 (GLOBE NEWSWIRE) -- Ritter Pharmaceuticals, Inc. (Nasdaq: RTTR) (“Ritter Pharmaceuticals” or the “Company”), a developer of innovative therapeutic products that modulate the gut microbiome to treat gastrointestinal diseases, announced today that its Phase 3 clinical trial of RP-G28 for lactose intolerance (LI) failed to demonstrate statistical significance in its pre-specified primary endpoint.

Top-line data from the 557-subject Phase 3 clinical trial indicates that RP-G28 provided significant symptom improvement in patients; however, there was no or little difference compared to placebo. In the primary endpoint, measuring LI symptom1 reduction at day 61 (30 days post-treatment) compared to baseline, the treatment group reported a 3.159 mean reduction compared to a reported 3.420 mean reduction in the placebo group (p-value, one-sided = 0.106). Additionally, RP-G28 missed its first secondary endpoint of responders with a meaningful treatment benefit: 36.2% of treatment group compared to 34.1% of placebo group (p-value, one-sided= 0.284). The remaining secondary endpoints also missed statistical significance differences with treatment and placebo generally reporting similar results to each other. RP-G28 was generally well-tolerated, with placebo and treatment groups reporting similar safety profiles.

The Phase 3 multicenter, randomized, double-blind, placebo-controlled, clinical trial enrolled 557 subjects with LI and was designed to determine the efficacy, safety and tolerability of RP-G28 for LI. Participants underwent a 2-week screening period, followed by a randomized 30-day study drug treatment period, then a 90-day “real-world experience” period to assess study drug response and durability of effect after treatment as patients consume their normal diets, including dairy products.

“We are deeply disappointed in the results of the phase 3 clinical trial,” said Andrew J. Ritter, CEO at Ritter Pharmaceuticals. “We believe the clinical trial was well-designed and executed. We are continuing to analyze the results of the trial to better understand the data and clinical outcomes to assess a path forward, which may include alternative strategic options for the Company.”
