Dilafor signs a binding term sheet with Exeltis for a license regarding tafoxiparin in Priming of Labor

STOCKHOLM, SWEDEN – January 21, 2026. Dilafor has signed a binding term sheet with Exeltis, a global Women’s Health company, for an exclusive semi-global license (excluding China and Japan) to its lead candidate drug tafoxiparin. Exeltis will fund pivotal clinical trials, development and commercialization of tafoxiparin for priming of labor. The deal offers Dilafor significant upside through sales-based milestone payments and up to double-digit royalties on net sales, alongside limited upfront and development-based milestones. Dilafor has signed a binding term sheet with Exeltis for a license to develop and commercialize tafoxiparin as a potential new treatment for priming of labor. Exeltis will fund all future development and commercialization costs for tafoxiparin as the candidate drug faces pivotal phase 3 trials. The deal includes milestone payments primarily linked to commercial performance, as well as stepped royalties that increases based on net sales. “We are excited to initiate the collaboration with Exeltis, an engaged pharmaceutical player in the field of Women’s Healthcare. This binding term sheet implies great opportunities to progress the clinical development of tafoxiparin. At a later stage it could enable a fundamental change in the treatment options for pregnant women, shifting care from hospital surveillance to treatment at home. Maternity care is undergoing a global transformation following recognition of a significant risk of fetal death in pregnancies that continue beyond the expected due date. Therefore obstetricians are compelled to induce labor earlier. The inductions have been increased to 30-40 % especially in first time mothers. Against this backdrop, tafoxiparin has blockbuster sales potential and we are convinced that tafoxiparin will play a disruptive role to solve this increased demand of inductions by offering a safe, effective treatment planned for home use by the mother” says Lena Degling Wikingsson, CEO Dilafor.

The company was founded in 2003 by scientists from Karolinska Institutet, Lund University, Uppsala University, and experts with significant experience from the pharmaceutical industry. Dilafor is dedicated to the development of pharmaceutical products aimed at minimizing the risk of maternal and fetal complications associated with labor. The company’s leading drug candidate, tafoxiparin, is clinical phase 3 ready for priming of labor. Tafoxiparin has a unique mechanism of action, mimicking the normal physiological process, preparing both the cervix and the uterus for the onset of labor, thereby increasing the likelihood of a normal vaginal delivery. The drug candidate uniquely initiates both cervical ripening and myometrial remodeling over several days, initiating an onset of labor leading to a vaginal delivery without traditional mechanical or pharmacological interventions. Tafoxiparin is the first drug developed for self-administration by the mother using a daily autoinjector at home, marking a possible improvement in quality of life for the pregnant woman and her family. Moreover, the tafoxiparin drug candidate has in Phase II studies demonstrated potential to reduce fetal and maternal complications and associated healthcare expenses. The main owner of Dilafor is KDev Investments AB, which is jointly owned by Karolinska Development AB (publ) and Rosetta Capital IV. The other main owners are Opocrin S.P.A and the Foundation for Baltic and European Studies (Östersjöstiftelsen). For more information, please visit: www.dilafor.com
