  Celanese’s VitalDose® Drug Delivery Platform will enable a long-acting, patient-centric formulation for Meliodays’ IUD design Munich, July 29, 2025 – Meliodays Medical and Celanese Corporation (NYSE: CE) have signed an agreement related to Meliodays’ pre-clinical development of MelioOne®, the first hormone-free non-contraceptive intrauterine device (IUD) designed to deliver localized relief for menstrual pain. MelioOne® combines the proven VitalDose® Drug Delivery Platform from Celanese with Meliodays’ innovative IUD design and non-hormonal active pharmaceutical ingredient (API). “More than 80% of menstruating people experience period pain and cramps”, says Simone Sabbione, CEO and Co-Founder of Meliodays. “Our partnering with Celanese marks the first milestone in achieving our mission to revolutionize menstrual pain management solutions. Our localized release targets pain at its source, avoiding the systemic side effects often associated with oral intake of pain medication. Given the significant impact of period pain on work, school and social life, we are proud to be leading the way with Celanese to enable menstruating women to have a natural cycle without compromising their lives.” “We are excited to partner with Meliodays in its early development of an IUD in hopes that it ultimately progresses into treatment plans prescribed by healthcare providers to relieve women of menstrual pain,” says Brian Duke, Sr. Marketing Manager of Pharmaceutical Solutions at Celanese. “Our Celanese team is proud that the VitalDose® Drug Delivery Platform has been used in our customers’ patient-centric therapies that have provided convenient yet efficacious treatment for women for so long. We will continue to advance its use in therapies for women and anywhere sustained drug delivery provides benefits.” The VitalDose® Drug Delivery Platform provides reliable, controlled-release performance for a wide range of molecule types and has a long history of use in approved parenteral drug products in the United States and Europe. It has been used in patient-centric dose forms which enable treatments for women's health for more than two decades.
