Lancet Rheumatology Publishes Phase 2b Data on Eupraxia Pharmaceuticals' EP-104IAR for the Treatment of Knee Osteoarthritis

• Publication of Eupraxia's Phase 2b data in Lancet Rheumatology, a distinguished and respected journal, raises the profile of EP-104IAR.
• As outlined in Lancet Rheumatology, Eupraxia's EP-104IAR imparts clinically significant and durable pain relief, while also having minimal changes in glucose and cortisol, along with stable fluticasone proportionate concentrations in plasma.
• The U.S. Centers for Disease Control and Prevention estimates that knee osteoarthritis affects more than 30 million people in the U.S. alone.

VICTORIA, BC, Oct. 15, 2024 /CNW/ - Eupraxia Pharmaceuticals Inc. ("Eupraxia" or the "Company") (NASDAQ: EPRX) (TSX: EPRX), a clinical-stage biotechnology company leveraging its proprietary DiffuSphere™ technology to optimize drug delivery for applications with significant unmet need, today announced that Lancet Rheumatology, a leading independent, peer-reviewed journal committed to sharing progressive content relevant to rheumatology specialists worldwide, recently published Eupraxia's Phase 2 data from its SPRINGBOARD trial evaluating EP-104IAR for the treatment of knee osteoarthritis.

The publication is titled, "Efficacy and safety of a novel extended-release fluticasone propionate intra-articular injection (EP-104IAR) in knee osteoarthritis: a randomized, vehicle-controlled, double-blind, multi-centre, 24- week, Phase 2 trial (SPRINGBOARD)". A link to the paper can be found here.

"The publication of our Phase 2b data in a distinguished and respected journal such as Lancet Rheumatology raises the profile of EP-104IAR and further underscores the potential of this product candidate to become a best-in-class therapy for the treatment of knee osteoarthritis," said Dr. James Helliwell, CEO of Eupraxia. "As outlined in the publication, EP-104IAR imparts clinically significant and durable pain relief, while also having minimal changes in glucose and cortisol, along with stable fluticasone proportionate concentrations in plasma. We continue to evaluate multiple program advancement strategies for this exciting and highly differentiated Phase 3-ready clinical asset that we believe holds the potential to advance the standard of care for individuals suffering from knee osteoarthritis."

"By utilizing an advanced formulation technology, the improved pharmacokinetic and pharmacodynamic profile of EP-104IAR appears to offer strong and sustainable pain relief and shows the potential to significantly improve upon the safety profile for this drug class," said Philip Conaghan, Professor of Musculoskeletal Medicine, University of Leeds, and an author of the publication. "Based on the data from this Phase 2 study, I look forward to seeing this product candidate continue to advance into late-stage, pivotal testing."

The SPRINGBOARD trial is a multi-centre, randomized, double-blind, vehicle controlled, parallel-group Phase 2b clinical trial that evaluated EP-104IAR for the treatment of knee osteoarthritis. Participants (N=318) were evaluated following a single IA dose of 25 mg EP-104IAR or vehicle placebo. The objectives of the study were to evaluate the efficacy, safety and pharmacokinetic profile of EP-104IAR. The 24-week duration of the trial was anticipated to cover the period over which fluticasone propionate is released via diffusion from the EP-104IAR particles.

In June 2023, the Company announced positive results from the Phase 2b clinical trial of EP-104IAR for pain associated with knee osteoarthritis. EP-104IAR met its primary endpoint with a clinically significant and statistically significant (p=0.004) improvement over vehicle-placebo in WOMAC Pain at 12 weeks. EP-104IAR also showed statistically significant improvement over placebo at 12 weeks in three of four secondary endpoints: WOMAC Function (p=0.014), OMERACT-OARSI strict responders (p=0.011) and Area Under the Curve (AUC) for WOMAC Pain (p<0.001). Importantly, statistical significance with OMERACT-OARSI strict pain responders to 15 weeks and Area Under the Curve for WOMAC Pain to 24 weeks was also seen in the Phase 2b study, highlighting a strong and durable response.

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 eosinophilic esophagitis ("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. 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.
