Consistent improvement in patient reported outcomes with 10 of 11 evaluable patients in the first four cohorts experiencing a reduction in symptom (SDI1) scores at 12 weeks The fourth cohort showed the greatest percentage change in histology (EoEHSS2) scores of any cohort to date The RESOLVE Phase 1b/2a trial is progressing as anticipated with no serious adverse events reported in all four fully-dosed cohorts VICTORIA, BC, Sept. 11, 2024 /PRNewswire/ - Eupraxia Pharmaceuticals Inc. ("Eupraxia" or the "Company") (TSX: EPRX) (NASDAQ: EPRX), a clinical-stage biotechnology company leveraging its proprietary DiffuSphere™ technology to optimize drug delivery for applications with significant unmet need, today announced additional positive clinical data from its RESOLVE Phase 1b/2a trial, which is evaluating the safety and efficacy of EP-104GI as a treatment for eosinophilic esophagitis ("EoE"). New Clinical Data from the Fourth Cohort of the RESOLVE Trial The results announced today from the fourth cohort of the RESOLVE trial, using Eupraxia's DiffuSphere™ technology for EoE, are derived from twelve 2.5 mg injections of EP-104GI (total dose of 30 mg) administered to less than two-thirds of each patient's lower esophagus. The data show: Straumann Dysphagia Index ("SDI")1, a patient-reported outcome measure designed to assess symptom severity, was lower for all three patients post-administration with peak reductions up to four points (67% from baseline). At 12 weeks post-administration, SDI was reduced by a mean of 45% or 3.3 points – a level comparable with currently approved therapies. Eosinophilic Esophagitis Histology Scoring System ("EoEHSS")2 scores, which evaluate the severity and extent of EoE, showed the largest percent reduction of any cohort to date, with a mean 39% reduction in Composite Stage and a mean 37% reduction in Composite Grade at 12 weeks – a level comparable with currently approved therapies. Using data from four biopsy sites, which is consistent with the U.S. Food and Drug Administration ("FDA") Guidance for Developing Drugs for the Treatment of EoE, the mean reduction in Peak Eosinophil Counts ("PEC")3 was 67% at 12 weeks. Notes "The RESOLVE trial is progressing rapidly and we continue to observe positive data on efficacy and safety outcomes with EP-104GI, with the fifth cohort expected to read out in November 2024," said Dr. James Helliwell, Chief Executive Officer of Eupraxia. "Overall, we are encouraged by the data that we have seen across a number of key metrics and remain optimistic that we'll see further improvements in patient response as the trial progresses towards an optimal dosing level." The RESOLVE trial is a Phase 1b/2a, multicentre, open-label, dose-escalation study to evaluate the safety, tolerability, pharmacokinetics, and efficacy of EP-104GI in adults with histologically confirmed, active EoE. EP-104GI is administered as a single dose via 4 to 20 injections into the esophageal wall. Dose escalations increase the dose per site and/or number of sites. Participants in the first through the fourth cohorts will be assessed for up to 24 weeks. Patients in cohorts five and above will be assessed for 52 weeks. Dr. Helliwell added, "In each of the trial's successive cohorts, patients are injected with EP-104GI at either higher doses or across a greater number of injection sites. We anticipate that the dose-escalating cohorts will allow us to evaluate the trial's emerging dose-response relationship. In addition, biopsies measuring tissue health have demonstrated a correlation between the dose of drug and the response on histology. This is exactly the outcome we hope to see in a dose-escalation trial such as this." Dr. Evan S. Dellon, MD, MPH (University of North Carolina School of Medicine) and Chairman of the Company's Gastrointestinal Clinical Advisory Board, commented, "I'm encouraged to see the positive trends in the SDI1, EoEHSS2 and PEC3 scores as the trial continues. These metrics have emerged as key data points to help clinicians better understand a patient's esophageal health and will be important in informing the design of the Company's late-stage clinical trials. We believe that EP-104GI has the potential to contribute to improved overall esophageal health in patients, in part, because it is being injected into the deeper areas of the esophagus versus coating the surface of the tissues, which may help to improve esophageal remodeling." The Company intends to continue to periodically disclose additional data from the trial. New Clinical Data from the Third Cohort in the RESOLVE Trial The results announced today from the third cohort of the RESOLVE trial, using Eupraxia's DiffuSphere™ technology for EoE, are derived from eight 2.5mg injections of EP-104GI (total dose of 20 mg) administered to a portion of each patient's lower esophagus. The data show: SDI1 was 50% lower in one of two evaluable patients at 24 weeks. A third patient in this cohort discontinued evaluation for reasons unrelated to the study. EoEHSS2 Composite Stage and Composite Grade scores were both lower than baseline at 12 weeks post-administration, showing an average reduction of 7% and 15%, respectively. Using data from four biopsy sites, which is consistent with the FDA Guidance for Developing Drugs for the Treatment of EoE, the mean reduction in PEC3 was 55% at 12 weeks. About EoE EoE is an inflammatory-mediated disease in which white blood cells migrate into and become trapped in the esophagus, creating pain and difficulty with swallowing food. According to market research from Clearview, EoE affects more than 450,000 people in the United States and has been identified by the American Gastroenterological Association as rapidly increasing in both incidence and prevalence. Impacts from both symptoms and interventions frequently lead to mental health issues, compounding the disease burden of EoE for both the healthcare system and the individual. About Eupraxia Pharmaceuticals Inc. Eupraxia is a clinical-stage biotechnology company focused on the development of locally delivered, extended-release products that have the potential to address therapeutic areas with high unmet medical need. DiffuSphere™, a proprietary, polymer-based micro-sphere technology, is designed to facilitate targeted drug delivery of both existing and novel drugs. The technology is designed to support extended duration of effect and delivery of drugs in a hyper-localized fashion, targeting only the tissues that physicians are wanting to treat. We believe the potential for fewer adverse events may be achieved through the precision targeting and the stable and flat delivery of the active ingredient when using the DiffuSphere™ technology, versus the peaks and troughs seen with more traditional drug delivery methods. The precision of Eupraxia's DiffuSphere™ technology platform has the potential to augment and transform existing FDA-approved drugs to improve their safety, tolerability, efficacy and duration of effect. The potential uses in therapeutic areas may go beyond pain and inflammatory gastrointestinal disease, where Eupraxia currently is developing advanced treatments, to also be applicable in oncology, infectious disease and other critical disease areas. Eupraxia's EP-104GI is currently in a Phase 1b/2a trial, the RESOLVE trial, for the treatment of EoE. EP-104GI is administered as an injection into the esophageal wall, providing local delivery of drug. This is a unique treatment approach for EoE. Eupraxia also recently completed a Phase 2b clinical trial (SPRINGBOARD) of EP-104IAR for the treatment of pain due to knee osteoarthritis. The trial met its primary endpoint and three of the four secondary endpoints. In addition, Eupraxia is developing a pipeline of later and earlier-stage long-acting formulations. Potential pipeline indications include candidates for other inflammatory joint indications and oncology, each designed to improve on the activity and tolerability of currently approved drugs.
