Press release: Precision oncology company Flindr Therapeutics announces €20 million
Series A financing to advance first-in-class small molecule inhibitors 


  • V-Bio Ventures leads international syndicate which includes Johnson & Johnson Innovation – JJDC, Inc., QBIC Fund, Flanders Future Tech Fund, Curie Capital as well as seed investors Oncode Oncology Bridge Fund, Swanbridge and BOM
  • Flindr discovers and develops precision oncology therapeutics with the potential to eradicate
    tumors in specific patient populations
  • Lead asset is a first-in-class small molecule inhibitor of the cancer driver RNF31


Oss, the Netherlands, 24 April 2024 – Flindr Therapeutics B.V. (“Flindr” or “the Company”), a precision oncology therapeutics company, today announces a €20 million Series A financing to advance its pipeline of first-in-class, small molecule inhibitors for treatment of cancer. V-Bio Ventures led the financing alongside other new investors Johnson & Johnson Innovation – JJDC, Inc. (JJDC), QBIC Fund, Flanders Future Tech Fund and Curie Capital, as well as existing investors Oncode Oncology Bridge Fund, Swanbridge and Brabantse Ontwikkelings Maatschappij (BOM).

Flindr combines world class science and expertise in translational biology, cancer target identification, immuno-oncology and small molecule oncology drug development. The expert team has a successful track record in the identification and development of covalent small molecules inhibitors from discovery to market approval.

The Company utilizes the “ImmunoGram Drug Discovery Engine”, which has evolved from seminal work in the laboratories of the Netherlands Cancer Institute (NKI) and the Oncode Institute. This approach involves reverse-translating the heterogeneity in tumor-specific and host-specific factors, as commonly seen in patients in the clinic, into lab-based biological models to screen for and select the most important drug targets involved in patient clinical response.

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. The Company has already obtained highly promising activity for the drug candidate in preclinical ovarian cancer and B-cell lymphoma models, and identified biomarkers which will help select patients most likely to respond to treatment with RNF31 inhibitors. Flindr will use the funds to progress its lead program to IND, develop an exciting second program, and broaden its pipeline using the ImmunoGram Drug Discovery Engine.

Flindr Therapeutics was created in 2020, with Maarten Ligtenberg as the founding CEO, and initial
seed financing from BOM, Oncode Oncology Bridge Fund, Swanbridge Capital and Innovatiefonds Noord Holland. In 2023, Flindr joined forces with VIB, Flanders’ leading life sciences research institute, and the lab of Professor Rudi Beyaert (of the VIB-UGent Center for Inflammation Research), to leverage their deep expertise of immunology – including RNF31 biology – and development of animal cancer models. Their work with Flindr in these areas will provide further validation of RNF31 as a target and will enable the Company to make safety predictions.

Maarten Ligtenberg, PhD, Chief Executive Officer and Founder at Flindr, said: “This €20 million Series A financing will help us translate our precision targets into precision therapies, with the ultimate goal of potentially transforming the lives of patients with cancer. The backing of this highly regarded investor syndicate is a strong validation of our unique approach and the potential of our pipeline.”

Christina Takke, Managing Partner at V-Bio Ventures, commented: “We strongly believe that a
complementary team is crucial for any success. The Flindr team combines well-established
identification expertise from the NKI with world class biological insights from VIB, and its deep
experience and successful track record in the identification and development of covalent small
molecules inhibitors.”

Following financing, the Flindr Supervisory Board of Directors will include Christina Takke, V-Bio
Ventures, Chris De Jonghe, Oncode Institute, Tine Bekaert, Flanders Future Tech Fund, Cedric van
Nevel, QBIC Fund and Allard Kaptein, CEO of Genase Therapeutics and Chief Strategy Officer of
IMMIOS, as well as a representative of JJDC.
