EXHIBIT 99.1
Eupraxia Pharmaceuticals Reports 52-Week Data from the Highest Dose Cohort of EP-104GI in its Ongoing Phase 1b/2a RESOLVE Trial for the Treatment of Eosinophilic Esophagitis
- The highest dose group of EP-104GI (Cohort 9) demonstrated durability of symptom responses out to 52 weeks, with 66% of patients (2 of 3) maintaining clinical remission1
- The second highest dose group of EP-104GI (Cohort 8b) continued to show meaningful histologic reduction in inflammation and fibrosis with Stage –0.26 and Grade –0.27 in EoEHSS at 36 weeks
- The Cohort 8b and Cohort 9 responses are consistent with clinical and histologic responses seen across all cohorts analyzed to date; in total, 9 of 14 patients (64%) have remained in clinical remission 52 weeks after receiving a single administration of EP-104GI
VANCOUVER, British Columbia, Sept. 30, 2026 (GLOBE NEWSWIRE) -- Eupraxia Pharmaceuticals Inc. (“Eupraxia” or the “Company”) (NASDAQ:EPRX) (TSX:EPRX), a clinical-stage biotechnology company leveraging its proprietary Diffusphere™ technology designed to optimize local, controlled drug delivery for applications with significant unmet need, today announced updated clinical data from the Phase 1b/2a RESOLVE study highlighting the long duration of response, high remission rates and tolerability of EP-104GI for the treatment of Eosinophilic Esophagitis (“EoE”).
“The 52-week and 36-week data from the highest dosing cohorts of the Phase 1b/2a RESOLVE trial further strengthen the observed durable treatment effects of EP-104GI in EoE patients,” said Dr. James Helliwell, Chief Executive Officer of Eupraxia. “In total, we have observed 64% of patients remaining in clinical remission over this 52-week period in addition to clinically meaningful histologic improvements. If achieved, an annual dosing regimen could align well with ACG Guidelines supporting routine endoscopic monitoring of EoE patients.”
“These encouraging efficacy and durability data suggest that EP-104GI may have the potential to treat patients suffering with EoE with a single annual dose,” said Dr. Jeymi Tambiah, Chief Medical Officer of Eupraxia. “We have not observed any treatment-related Serious Adverse Events (SAEs) to date or adverse events related to corticosteroid exposure, such as abnormal changes to glucose levels. Oropharyngeal Candidiasis has not been observed in any of the 10 cohorts to date.”
Key New Findings from the RESOLVE Phase 1b/2a Trial
Symptom Response and Clinical Remission as Measured by SDI
Symptom response is measured in the open-label portion of the RESOLVE study using the Straumann Dysphagia Index (SDI), a measure of both frequency and intensity of dysphagia on a 10-point scale (ranging from 0-9). A reduction compared to baseline in the SDI of at least 3 points is defined as clinical remission1.
Newly reported data include the following:
- In Cohort 8b n=4 (20 x 6 mg dose), which was distinguished for Cohort 8 by employing an improved injection technique, the mean reduction in SDI at 36 weeks was 3.3
- In Cohort 9 n=3 (20 x 8 mg dose), the mean reduction in SDI at 36 and 52 weeks was 3.0 at both timepoints
In total, the clinical remission rates across cohorts 5-9 (the cohorts for patients who are followed up to 52 weeks) are:
- At 12 weeks, 53% (10/19) of patients achieved clinical remission
- At 24 weeks, 78% (14/18) of patients maintained clinical remission
- At 36 weeks, 61% (11/18) of patients maintained clinical remission
- At 52 weeks, 64% (9/14) of patients maintained clinical remission
The clinical remission across these dose cohorts is illustrated in the figure below.

Tissue Health Outcomes as Measured by Eosinophilic Esophagitis Histology Scoring System (EoEHSS)
EoEHSS is a standardized scale used to estimate esophageal tissue damage in EoE patients. EoEHSS measures both grade (severity) and stage (extent) of inflammatory and fibrotic features of the disease from biopsies.
In the Phase 1b/2a portion of the RESOLVE trial, EoEHSS data were measured on all cohorts at baseline, week-4, week-12, and for patients in Cohorts 5-9 at week 36. Week 36 is the last timepoint at which histologic measurements are made in the study.
New data were reported for Cohort 8b (20 x 6 mg dose). The mean EoEHSS Stage and Grade reductions at week 36 were -0.26 (SD=0.13) and -0.27 (SD=0.20).

Safety and Tolerability Reported to Date in the Phase 1b/2a RESOLVE Study
- No treatment-emergent or procedure related SAEs.
- No cases of oropharyngeal candidiasis, a commonly reported adverse event associated with the use of swallowed steroids, have been reported.
- No cases of adrenal insufficiency or glucose derangement.
- EP-104GI has been generally well tolerated at all dose levels, including the highest dose of 8 mg/site at 20 injection sites (Cohort 9).
An updated summary of the above and previously announced clinical trial results is posted in the Investor Section of the Eupraxia Pharmaceuticals website and can be found here.
About the RESOLVE Trial
The Phase 1b/2a portion of the RESOLVE trial is a multicenter, open-label, dose-escalation study evaluating the safety, tolerability, pharmacokinetics, and efficacy of EP-104GI in adults with a history of confirmed active EoE. The treatment is administered as a single dose via 4 to 20 esophageal wall injections, with dose escalations modifying either the dose per site and/or the number of sites. Patients were followed for up to 24 weeks in Cohorts 1-4 (4x1mg, 8x1mg, 8x2.5mg and 12x2.5mg) or 52 weeks in Cohorts 5-9 (12x4mg, 16x4mg, 20x4mg, 20x6mg and 20x8mg). Eupraxia plans to disclose additional data from the open-label Phase 1b/2a portion of the RESOLVE trial in the coming months.
The Phase 2b portion of the RESOLVE trial, a randomized placebo-controlled study of EP-104GI, is currently recruiting both the 120mg (20x6mg) and 160mg (20x8mg) doses. The interim data from the Phase 2b portion of the RESOLVE trial are expected in December 2026.

About Eosinophilic Esophagitis (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 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.
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/2 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. In addition, Eupraxia is developing a pipeline of later and earlier-stage long-acting formulations. For further details about Eupraxia, please visit the Company's website at: www.eupraxiapharma.com.
