Preface
2025:
From Fundamental Insight to Societal Impact
The Netherlands ranks among the world leaders in cancer research. In 2025, it was once again evident how Oncode Institute contributes to this.
Within Oncode Institute, fundamental breakthroughs emerge that we further translate into concrete applications together with researchers, clinicians and partners. In 2025, Oncode Institute advanced fundamental research toward clinical application and societal impact.
Our results underscore this. Building on strong fundamental research, we are moving ever more decisively toward application. Innovations are finding their way into companies and securing follow-on funding, accelerating the transition to practice. Economically, this approach also led to new investments, spin-offs, and collaborations with public and private partners. For example, investments through the Oncology Bridge Fund triggered a significant increase in private investments, while new spin-offs build on this knowledge and contribute to a robust Dutch life sciences ecosystem.
What we do is clear: we accelerate the path from scientific insight to tangible impact for patients and society. By structurally connecting researchers, clinicians, companies, and patients, we ensure that knowledge does not remain limited in publications but is developed into applications that matter. Examples include the development of new therapeutic concepts, such as TEIPP, and targeted public-private partnerships, such as those with MRM Health and the Netherlands Cancer Institute. This brings new treatment strategies to the clinic faster.
Confidence in this approach is growing. In 2025, new and strengthened partnerships and investments reflected this, including with KiKa and through the Alpe d’HuZes/KWF Fund. The launch of Oncology Bridge Fund II, in collaboration with Ligase BioPartners, confirms that our model works and has the potential to grow even further.
Nevertheless, the societal urgency remains high. Pressure on the healthcare system is increasing, and the need for effective and affordable care is growing. The Wennink Report, an independent advisory report on the Netherlands’ future earning capacity, rightly calls for greater attention to capitalizing on our knowledge base. The report also rightly identifies biotechnology and life sciences as promising sectors. However, to enable the transition to a sustainable healthcare system, the Netherlands will also need to invest in the commercialization of new discoveries for which no financial commercial revenue model exists, but which do relieve the burden on the healthcare system. This requires not only additional resources but also a broader approach to innovation. Furthermore, the government has a coordinating role to play in partnering with the scientific community to invest in the societal commercialization of research.
That is where the societal need lies. We believe that translating publicly funded research into concrete applications is not a choice, but a responsibility. This requires continuity, scale, and the willingness of public and private parties to collaborate over the long term, while maintaining control over the further development of new discoveries into clinical practice.
In 2025, Oncode Institute demonstrated that this is possible. We are determined to strengthen this role in the coming years. Together with our researchers and partners, we are building an ecosystem in which knowledge drives better patient outcomes and contributes to a sustainable, innovative healthcare system.
Bertholt Leeftink
Bertholt Leeftink is the Managing Director of Oncode Institute, responsible for strategy, governance, and valorization at Oncode Institute — three core areas essential to shaping the organisation’s future. His appointment reflects Oncode’s ambition to further integrate science and impact in the years ahead. Leeftink brings a proven track record at the intersection of government, innovation, and business.
To further strengthen strategic alignment with Oncode Institute, Bertholt Leeftink, Managing Director of Oncode Institute, has been appointed as the new CEO and Chair of the Board of Directors of the Oncode Accelerator Foundation. Going forward, Bertholt will lead both organizations, which have distinct focus areas within a shared mission.
He previously served as CEO of NRG PALLAS, a global leader in the production of medical isotopes (2019–2024), and was Director-General for Enterprise and Innovation at the Ministry of Economic Affairs and Climate Policy. In this role, he played an instrumental part in the founding of Oncode Institute in 2017. Leeftink is a strong advocate for public-private partnerships, has been closely involved in creating Invest-NL, and brings broad experience across the life sciences sector and beyond. He holds a PhD in economics from the University of Amsterdam.
Jan Paul Medema
Jan Paul Medema is Scientific and chair of the Research Management Committee of Oncode Institute. He is also group leader at Amsterdam University Medical Centers and Professor Experimental Oncology and Radiobiology at the University of Amsterdam. His group studies the biology and therapy of colorectal cancer from a heterogeneity point of view considering both the intra tumor heterogeneity that is defined by a CSC hierarchy as well as by clonal evolution and inter-tumor heterogeneity, which is defined by distinct subtypes as well as mutation profiles.
