Pan Cancer T Secures EUR 10 Million to Advance First-in-Human Trial of Novel TCR-T Cell Therapy for Triple-Negative Breast Cancer

Rotterdam, the Netherlands – 8 December 2025 – Pan Cancer T B.V., a biotech company pioneering next-generation T cell therapies for solid tumours, today announced a EUR 10 million financing to advance its lead program, PCT1:CO-STIM, into a first-in-human clinical trial for women with triple-negative breast cancer (TNBC).

The financing includes EUR 5 million from existing investors Van Herk Ventures, Thuja Capital, Erasmus MC O&O Holdings, and InnovationQuarter, in addition to a EUR 5 million Innovation Credit loan from the Dutch Ministry of Economic Affairs. This funding will enable the company to treat TNBC patients at leading cancer centres in the Netherlands.

“Our mission is to empower a patient’s own immune cells to tackle hard-to-treat cancers like TNBC”, said Rachel Abbott, Chief Executive Officer of Pan Cancer T. “This significant investment marks a pivotal moment as we transition from preclinical validation to treating patients with our first novel T-cell receptor (TCR) T cell therapy, PCT1:CO-STIM, following our planned regulatory filing with the EMA in 2026. We are deeply grateful to our investors and the Netherlands Enterprise Agency (RVO) for their confidence in our approach.”

“Thuja Capital is dedicated to investing in the most innovative life sciences companies. Pan Cancer T’s TCR-T platform addresses hard-to-treat solid tumours, such as TNBC, that are the greatest challenge in oncology. Following our recent success in the cell and gene therapy field, with AstraZeneca’s acquisition of our portfolio company EsoBiotec, we are delighted to continue backing another pioneer in the C&GT space,” said Michel Briejer, Managing Partner at Thuja Capital and member of Pan Cancer T’s Supervisory Board.

The upcoming trial will assess safety, tolerability, and preliminary efficacy of a therapeutic dose of PCT1:CO-STIM in TNBC patients. These patients have an urgent unmet medical need, with a 5-year survival rate following metastatic progression of approximately 12% and median overall survival of less than 6 months.

PCT1:CO-STIM is being developed as an autologous T cell therapy but also has the potential to be delivered in vivo at a later stage. It features a proprietary TCR highly specific for ROPN1, a novel tumour-restricted target expressed in over 90% of TNBC and melanoma cases. The therapy also incorporates a unique co-stimulatory technology designed to overcome immune resistance in solid tumours, aiming to deliver durable responses in patients with few treatment options.
