About us
Flindr is building a pipeline of first-in-class small molecule inhibitors for the precision treatment of cancer. We are doing this using our ImmunoGram Drug Discovery Engine, which enables us to discover novel targets in both cancer cells and immune cells.
Flindr was founded in 2020 by the Netherlands Cancer Institute (NCI) and the Oncode Institute, which are both internationally renowned centers of excellence in cancer research. The Company’s strong scientific foundations are based on the seminal work of its founders Prof. Daniel Peeper, Prof. Christian Blank and Maarten Ligtenberg, who are experts in functional genomics and immunotherapy.
In 2024, Flindr entered into a collaboration with Vlaams Institute voor Biotechnologie (VIB) and the lab of Prof. Rudi Beyaert, a highly-regarded immunologist at the VIB-UGent Center for Inflammation Research. Prof. Beyaert is a world expert on the pathway biology of our lead program, RNF31. VIB also became a shareholder in Flindr. The NCI, the Oncode Institute and the VIB bring well-established expertise in target discovery and validation, deep cancer biology insight and translation of research in new treatment paradigms to Flindr.

Origin of the Company name
The name Flindr
The name
Flindr
Flindr is based on the Dutch word for butterfly – an organism that goes through a series of incredible changes before emerging as the amazing creature. Similarly, our Immunogram-enabled drug targets must undergo metamorphosis to be transformed into the next-generation of innovative cancer medicines. We find beauty in this vital process – in the iterative cycle of target identification and validation, assay development, medicinal chemistry, safety and efficacy assessment – to eventually reach the final outcome of a new first-in-class therapeutic.
Leadership


Maarten Ligtenberg
Founder / Chief Executive OfficerMaarten Ligtenberg is the co-founder and CEO of Flindr and has more than 10 years of experience in the oncology field, in particular immuno-oncology and cancer target identification. Flindr (formerly Immagene) was spun out of the Netherlands Cancer Institute (NKI) and Oncode Institute in 2020, by founders Prof Daniel Peeper, Prof Christian Blank and Dr Maarten Ligtenberg and joined forces with Professor Rudi Beyaert of VIB in 2023. Flindr utilizes the “ImmunoGram Drug Discovery Engine” to build a pipeline of first-in-class, small molecule inhibitors for treatment of cancer. Flindr’s lead program is a first-in-class small molecule inhibitor of RNF31 (also known as HOIP), a protein-stabilizing E3 ubiquitin ligase which is aberrantly activated in solid and hematological malignancies.
Maarten completed his doctoral degree at the Karolinska Institutet in the Kiessling lab and was as postdoctoral fellow in the Peeper lab at the NKI.


Jac Wijkmans
Chief Scientific OfficerJac joined Flindr in 2020 to lead drug discovery and strategy. Jac brings over 25 years of pharma experience in leading R&D operations and managing complex multidisciplinary innovation projects and processes. He held multiple senior management positions spanning the full spectrum of the industry from academic spin-offs (Oxford Asymmetry, Griffin Discoveries) and mid-size biotech (British Biotech, OSI Pharmaceuticals) to Big Pharma (Merck & Co, Schering-Plough, Organon). Jac is a medicinal chemist by training and under his leadership, multiple small-molecule drug candidates were identified, optimized and selected for pre-clinical and clinical studies. Jac has a PhD in Bioorganic Chemistry from Leiden University.


Christian Blank
FounderChristian Blank obtained his MD from the Medical School of the Technical University Munich, Germany, where he also completed his Doctoral thesis (summa cum laude) at the Department for Medical Microbiology in 1997. As a Junior House Officer (1997–1998) Dr Blank held four positions at the Departments of Cardiology and of Radiology at the University Clinic Munich Rechts der Isar, Munich, the Accident and Emergency (A&E) Departments at the Royal Infirmary of Edinburgh, Scotland, and the University of Birmingham, England, UK.
He went on to attain the position of Physician at the Department of Haematology and Oncology, University of Regensburg, Germany (1998–2001). During 2001–2003, Dr Blank held a Postdoctoral Research Fellowship at the lab of Professor Thomas Gajewski, University of Chicago, IL, USA. Subsequently he was appointed as Physician and Research Group Leader at the Department of Haematology and Oncology, University of Regensburg, Germany (2003–2007). Dr Blank has obtained two Specialist Degrees in Internal Medicine (2007) and in Haematology/Oncology (2009).
Since 2007, he has been appointed Staff Member at the Department of Medical Oncology, and a Group Leader at the Division of Molecular Oncology and Immunology, The Netherlands Cancer Institute – Antoni van Leeuwenhoek Hospital (NKI-AVL), Amsterdam. In 2010, Dr Blank became University Lecturer (Privatdozent) at the University of Regensburg. In addition to his academic background, Dr Blank obtained his Master of Business Administration (MBA), from the University of Warwick, England, UK (2006). Dr Blank is committed to teaching, lecturing on medical courses at the NKI-AVL and the Medical School of the University of Regensburg, where he was appointed Professor in 2015. He is a member of several prestigious societies, including ESMO and ASCO. Dr Blank has been an invited speaker at more than 200 national and international congresses and is the author of more than 200 publications. His research interests broadly include neoadjuvant immunotherapies, targeted and biological response modifiers, and prognostic markers for cancer immunotherapies.


Daniel Peeper
FounderDaniel Peeper heads the Department of Molecular Oncology & Immunology at the Netherlands Cancer Institute (NKI). He holds a professorship in Functional Oncogenomics at the VU University Amsterdam (since 2008) and is a member of Oncode (since 2017). At the NKI, he chaired the Research Faculty Council (2012-2024) and the Translational Research Board (2014-2019).
Peeper studied Medical Biology at the VU University Amsterdam (1988) and received his PhD in the laboratory of Alex van der Eb (Leiden, 1994) for his work on adenovirus oncoproteins and cell cycle proteins. He did his postdoctoral work in the lab of Mark Ewen (Dana-Farber Cancer Institute, Harvard Medical School, Boston, 1994-1995) and subsequently in the lab of René Bernards (NKI, till 2000).
His laboratory uses function-based genomic approaches to identify critical cancer and immune genes. They were the first to discover Oncogene-Induced cellular Senescence (OIS) as a tumor suppressor mechanism in humans, and dissected the underlying mechanism. Other discoveries include AXL as a target for therapy-resistant cancers and the mechanism of cancer drug addiction. More recently, his laboratory focused on immunotherapy resistance, to develop rational cancer treatments combining tumor and immune cell interventions. His team uncovered mechanisms causing immunotherapy resistance, and identified several therapeutic targets, both in cancer cells and in T cells. Many of the team’s findings were published in top-tier journals including Nature, Cancer Cell and Cell. The successful identification of new therapeutic IO targets led him to co-found an NKI/Oncode spin-off company in immuno-oncology (Flindr Tx, previously Immagene).
Peeper has received several awards, including a KWF Queen Wilhelmina Award and Society for Melanoma Research (SMR) Junior researcher and Outstanding researcher Awards. He is a Member of Oncode, EMBO and Academia Europaea, and has been serving on the Board of the European Association for Cancer Research (EACR) from 2012-2022, and on several CRUK review panels including the Discovery Research Committee. His lab received many prestigious grants, including ERC.
