The assets acquired from Celmatix include a first-in-class oral Follicle-Stimulating Hormone (FSH) receptor agonist with the potential to transform fertility care by enabling more patient-friendly ovarian stimulation. The portfolio also features a novel Jun N-terminal kinase (JNK) inhibitor, which represents a potential non-hormonal immunotherapy approach for endometriosis aimed at addressing both pain and inflammation. In addition, the acquisition comprises early-stage therapeutic antibodies targeting anti-Müllerian hormone (AMH), including both agonists and antagonists, with the potential to provide unprecedented control over ovarian folliculogenesis.
This transaction further advances Richter’s strategy to expand its innovative drug development capabilities across key women’s health indications, including fertility, endometriosis and ovarian ageing. The development of the acquired programs will be led by the women's health original R&D hub of Richter in Belgium. The integration of these assets within the Belgian hub reinforces its role as the focal point for innovation in women’s health, leveraging its scientific expertise within the framework of Richter’s strategic priorities.
Under the asset purchase agreement, Celmatix will receive an upfront payment and will be eligible to receive development milestone payments as the drug pipeline advances into clinic and registration phase.
Dr. Péter Turek, Head of Women’s Healthcare Business Unit at Richter, commented: “For too long, women’s health has been overlooked and despite medical progress, women are left with major unmet medical needs. By advancing research in key therapeutic areas of women’s health such as endometriosis, ovarian ageing and infertility, we are strengthening our pipeline and broadening the scope of our scientific platform and innovation engine. This is fully in line with our ambition to become a thought leader in women’s healthcare and to deliver innovative solutions that have the potential to meaningfully improve the lives of millions of women worldwide”.
Dr. Piraye Yurttas Beim, Founder & CEO of Celmatix, added: “Our mission has centered on three core realities of modern women’s health. First, women need all their organs, including their ovaries, to function well throughout their lifespan. Second, chronic conditions such as endometriosis require disease-modifying, first-line treatments early in life to prevent downstream health consequences. And third, as women increasingly seek not just to survive but to thrive into their later years, they deserve access to more advanced fertility care. Expanding ovarian function across the lifespan, addressing endometriosis at its root rather than managing symptoms, and pioneering a paradigm shift in the therapeutic treatment of infertility have been foundational pillars of our work. It became clear to us that Gedeon Richter, with its long-standing legacy in women’s health and its deep, sustained commitment to innovation, is the right home for these programs. Their scientific depth, global infrastructure, and multi-generational investment in this space give these assets the platform they ultimately need to reach patients. We are proud that this next chapter of the Celmatix portfolio will be written by a company that shares our vision and is prepared to advance it at global scale.”
