About us
A clinical-stage biopharmaceutical company
We are committed to advancing the next generation of ADCs, driving the transition to the new era of multifunctional therapies and precision oncology. Founded by leaders with a global mindset across oncology, chemistry and drug development, Adcytherix combines deep industrial experience with an agile, execution-driven operating model.
We focus on areas of high unmet medical need to help the patients we care for by focusing on approved cancer drugs as payloads, combined with appropriate conjugation design and translational research. Driven by a bold ambition, our team is building a highly differentiated ADC powerhouse to tackle cancers that still resist today’s science and technology.
Driving the development of transformational ADC technology
At Adcytherix, we believe that innovation in payloads and sophisticated conjugation engineering shape the future of ADCs. Overcoming resistance, enhancing efficacy and fine-tuning the balance between stability and payload release are the three levers that will enable ADCs to expand the curative potential of targeted therapies.
By harnessing innovative payloads derived from approved cancer drugs and integrating them into optimized, next-generation ADCs, we aim to tackle resistance against today’s ADCs and broaden the therapeutic window to widen the addressable indications of ADCs in oncology.
Transforming Innovation into Patient Impact
At Adcytherix, transforming innovation into patient impact means looking beyond the science to understand the real-world needs of people living with cancer and those who support them. A diagnosis affects not only patients, but also their families, care partners, and the broader community.
By designing ADCs that address resistance and deliver greater precision, tolerability, and meaningful clinical benefits, we aim to improve outcomes and quality of life. We value the insights of patients, advocacy groups, and care networks, whose experiences help shape therapies that truly meet patient needs. Our commitment extends beyond developing next-generation ADCs: we strive to be a responsible, engaged, and compassionate partner to the cancer community.
