HYLORIS PHARMACEUTIC

Access to Alenura^TM, a dual mode-of-action advanced clinical candidate for the treatment of acute pain in interstitial cystitis/bladder pain syndrome (IC/BPS)

Addressable patient population of at least 6 million¹ in the U.S.

Liège, Belgium – 17 December 2021 – Hyloris Pharmaceuticals SA (Euronext Brussels: HYL), a specialty biopharma company committed to addressing unmet medical needs through reinventing existing medications, today announces that it has entered into a strategic collaboration with Vaneltix Pharma, Inc. for the development and commercialisation of Alenura^TM as first-line drug treatment for acute pain in interstitial cystitis /bladder pain syndrome (IC/BPS).

Alenura^TM is a patented, innovative, clinical-stage bladder instillation product candidate that combines lidocaine, a well-established anaesthetic, in a new alkalinized form with heparin, a component of mucous membranes². Thanks to the novel dual mode-of-action, Alenura^TM has the unique potential to i) immediately relieve pain, and ii) augment the mucous layer of the bladder. In previous clinical studies, Alenura^TM was well-tolerated and demonstrated to be more effective in terms of pain relief, urgency response and improvement of symptoms compared to placebo, and lidocaine alone³.

Dr. Dan Vickery, Chief Executive Officer of Vaneltix Pharma, commented: “IC/BPS is a chronic bladder condition that results in recurring discomfort or pain in the bladder and surrounding pelvic region. Today, there is no cure available, and there are no products specifically approved to treat acute bladder pain. We have discovered and developed AlenuraTM to address these unmet medical needs and are very excited to partner with Hyloris to further develop AlenuraTM and bring much needed innovation to IC/BPS patients.”

Stijn Van Rompay, Chief Executive Officer of Hyloris, added: “With Alenura^TM, we are expanding our broad, patented value-added portfolio with a fourth new asset this year, delivering on our promise. The partnership with Vaneltix also perfectly fits within our strategy of increased focus towards repurposed medicines and addressing unmet medical needs to create a meaningful difference for patients. We are now preparing the next steps and anticipate the start of a larger Phase 2 comparative study and a Phase 2 multidose study mid 2022 for which the results could be available by late 2023.”

Under the terms of the agreement, Vaneltix will be responsible for the further development, manufacturing, regulatory affairs and commercialisation of Alenura^TM in collaboration with Hyloris. In return, Hyloris will provide staged investments of in total maximum USD 6.7 Mio for Phase 2, manufacturing and regulatory related activities and a loan of USD 0.5 Mio. Hyloris will be eligible to receive a tiered percentage of the product margin generated by Vaneltix.

About Interstitial Cystitis /Bladder Pain Syndrome (IC/BPS) and Alenura^TM

IC/BPS is a condition that results in recurring discomfort or pain in the bladder and surrounding pelvic region. The scientific team of Vaneltix, led by Dr. CL Parsons, a distinguished Professor Emeritus, Urologist and Surgeon, believes that ICS/BPS stems from an anatomical defect in the protective bladder lining (the GAG mucous layer) which exposes nerve endings to toxic components in urine. Patients often experience episodes of severe intensity pain lasting hours to days (painful flares), which requires treatment. IC/BPS is more prevalent in women, although men can experience symptoms as well, and although underdiagnosed, it is estimated at least 6 million¹ people in the U.S. suffer from the condition.

Alenura^TM is a unique, combination product of alkalinised lidocaine and the glycosaminoglycan heparin. Alkalinised lidocaine penetrates the transitional epithelial cell layer and provides immediate pain relief. Whereas heparin sodium is thought to augment the natural mucous layer of the bladder to prevent further irritation of the bladder and prolong the anaesthetic effect. Alenura^TM will be supplied as a prefilled syringe for intra-vesicular administration to the bladder through an installation procedure and is protected by multiple patents and patent applications potentially providing exclusivity up to 2038.
