The Meeting Highlights

Under terms of the announcement, Ritter Pharma announced that the Phase-3 clinical program will consist of two confirmatory clinical trials of similar trial design and size as the Company's Phase-2b/3 trial and will include additional components to allow for claims for durability of effect. The trials, according to the Company may run in parallel, where it anticipates initiating the Phase-3 program during the first half of 2018.

The protocol design, according to the announcement, will consist of multicenter, randomized, double-blind, placebo-controlled, parallel-group trials designed to determine the efficacy, safety, and durability of RP-G28 compared against placebo in subjects with lactose intolerance. The protocol design also includes screening to determine lactose intolerance, 30-day course of treatment, and 6-months of post-treatment observation. The primary endpoint will be the evaluation of a patient's composite LI symptoms, after a lactose challenge, comparing baseline symptom scores to 30-days post-treatment symptom to assess patient's clinically meaningful benefit. The secondary endpoint will evaluate LI signs and symptom and global assessment outcomes to evaluate and assess a patient's continued meaningful treatment benefit.

The Phase-2b/3 Trial and the RP-G28

The Phase-2b/3, multicenter, double-blind, placebo-controlled, parallel-group trial in 377 subjects was designed to determine the efficacy, safety, and tolerability of two dosing regimens of RP-G28 in subjects with lactose intolerance. RP-G28 is in fact, a novel, non-digestible oligosaccharide of ultra-high purity developed to module the gut microbiome by stimulating and adapting the bacteria in the gastrointestinal tract to metabolize lactose to improve lactose tolerance.

Under the trial, patients were assessed with lactose intolerance symptoms, measured on a Likert scale after a lactose challenge. Symptoms of abdominal pain, cramping, bloating, and movement were then combined into a composite endpoint representing the key symptoms of lactose intolerance. The composite primary endpoint was agreed to by the FDA prior to the unblinding the study results. The Phase-2b/3 trial design included a screening phase, a 30-day course treatment phase and post-treatment observation phase, during which subjects were followed while lactose-containing foods were reintroduced in their diets.

On August 03, 2017, Ritter Pharma announced additional findings and data analysis from its Phase-2b/3 study designed to evaluate lead candidate RP-G28 in subjects with lactose intolerance. These additional results from the trial analysis demonstrated that a clear drug effect was seen with a significant positive reduction in key symptoms of lactose intolerance and across a variety of global and real-world outcomes. The study demonstrated safety with no serious adverse events related to treatment.
