RedHill Biopharma Ltd. (the “Company”) announced today that it has regained the ex-North America rights to RHB-102 through a mutual agreement with Hyloris Pharmaceuticals SA (“Hyloris”) for the termination of the License & Development Agreement relating to the exclusive rights to RHB-102 across all indications and territories outside of North America (the “License Agreement”).

Under the parties’ mutual agreement, the License Agreement, dated February 24, 2025, has been effectively terminated on October 15, 2026, and Hyloris agreed to pay the Company a one-time break-up fee in the amount of $200,000. The termination of the License Agreement returns to RedHill all ex-North America rights to RHB-102, a once-daily, proprietary, bimodal extended-release oral tablet formulation of ondansetron, a 5-HT3 antagonist. With full worldwide rights to RHB-102, the Company continues its late-stage development for oncology support and GI indications, including GLP-1/GIP-associated GI intolerance, and proceeds with exploring potential partnerships.
