No serious adverse events reported in any of the five cohorts to date.\nCohort 6 is now fully enrolled and dosed, with 12-week data anticipated in Q1 2025.\n\nVICTORIA, BC, Nov. 12, 2024 /CNW/ - Eupraxia Pharmaceuticals Inc. (\"Eupraxia\" or the \"Company\") (TSX: EPRX) (NASDAQ: EPRX), a clinical-stage biotechnology company developing precision drug delivery for indications 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\").\n\n  \n\nNew Clinical Data from the Fifth Cohort of the RESOLVE Trial\nThe results announced today from the fifth cohort of the RESOLVE trial, for treatment of EoE, are derived from 12, 4 mg injections of EP-104GI (total dose of 48 mg) administered to the lower two-thirds of each patient's esophagus. The data show:\n\nOne patient achieved complete histological remission, defined by the presence of fewer than six eosinophils per high-powered field on esophageal biopsy.\nStraumann 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 3 points (50% from baseline). At 12 weeks post-administration, mean SDI reduction was 41% or 2.3 points.\nEosinophilic 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 at 12 weeks, with peak reduction of 100% in Stage and Grade scores, and a mean 54% reduction in Composite Stage and Grade scores.\nUsing 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 83% at 12 weeks.\n\nPlasma fluticasone levels continue to be predictable and well-below published levels of daily fluticasone asthma treatments. \"As the RESOLVE trial advances, we are observing increasingly positive data on efficacy and safety outcomes, including no adverse events such as candidiasis, adrenal suppression or glucose derangement,\" said Dr. James Helliwell, Chief Executive Officer of Eupraxia. \"Notably, higher dosing levels are yielding improved patient responses, such as histological remission, enhanced patient-reported symptom scores, and favourable histology results, all without reaching a maximum tolerated dose thus far.\"\nThe 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 four to 20 injections into a patient's esophageal wall. Dose escalations increase the dose per site and/or number of sites. Participants in the first through the fourth cohorts have been assessed for up to 24 weeks. Patients in cohorts five and above will be assessed for 52 weeks.\nThe Company intends to continue to periodically disclose additional data from the trial.\nNew Clinical Data from the Fourth Cohort in the RESOLVE Trial\nThe results announced today from the fourth cohort of the RESOLVE trial in EoE, are derived from 12, 2.5 mg injections of EP-104GI (total dose of 30 mg) administered to a portion of each patient's lower esophagus. The data show:\n\nSDI1 scores continued to improve out to 24 weeks (average four-point reduction), showing the largest reduction in scores for any cohort to date at this time point.\nEoEHSS2 Composite Stage and Composite Grade scores were both lower than baseline at 12 weeks post-administration, showing an average reduction of 39% and 37%, respectively.\nUsing 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 67% at 12 weeks. This compares favourably with 55% mean reduction in PEC in cohort 3.\n\nNotes \n\nStraumann Dysphagia Index, or SDI, is a patient-reported outcome score that uses a seven-day recall measuring dysphagia (trouble swallowing) severity and frequency. A reduction in SDI is a positive outcome for the RESOLVE trial.\nIn the Eosinophilic Esophagitis Histology Scoring System, or EoEHSS, grade indicates the severity of each of the eight histologic features assessed by the EoEHSS while stage indicates their extent. For the RESOLVE trial, these features include inflammation, increased cell production in a normal tissue or organ, and fibrosis, also known as fibrotic scarring, and five other features. A reduction in EoEHSS is a positive outcome for the RESOLVE trial.\nPeak Eosinophil Counts, or PEC, means the peak number of eosinophils found in esophageal biopsies. Eosinophils are one of several white blood cells that support a person's immune system. A reduction in PEC is a positive outcome for the RESOLVE trial.\n\nAbout EoE\nEoE 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 Healthcare Partners, 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.\nAbout Eupraxia Pharmaceuticals Inc.\nEupraxia 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.\nEupraxia'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.
