Oct 2025Series CV-Bio Ventures (lead); Inserm Transfert Initiative; Kurma Partners; Bpifrance; Pontifax; Sunstone Life Science Ventures; Hadean Ventures$44MStep Pharma, a clinical-stage biopharmaceutical company founded in 2014 by Kurma Partners, the Imagine Institute, and Sygnature Discovery based on discoveries by Prof. Alain Fischer and Dr. Sylvain Latour, is the global leader in CTPS1 inhibition for targeted cancer treatment. The company develops dencatistat, a first-in-class, highly selective, orally bioavailable CTPS1 inhibitor, which targets the pyrimidine synthesis pathway essential for DNA synthesis and cell proliferation in cancer cells. Dencatistat is advancing under a 'pipeline in a product' strategy across multiple indications, including lymphoma, solid tumors, and essential thrombocythemia. On October 15, 2025, Step Pharma completed a €38 million Series C financing round led by new investor V-Bio Ventures, with participation from existing investors Pontifax, Bpifrance, Kurma Partners, Hadean Ventures, Sunstone Life Science Ventures, and Inserm Transfert Initiative. Ward Capoen, Partner at V-Bio Ventures, joined the company's Board of Directors. The financing supports ongoing clinical development of dencatistat, enabling expansion of clinical datasets, completion of phase 1 studies, and progression into phase 2 while further derisking the asset. This round follows significant progress, including the initiation of dencatistat's third clinical program in essential thrombocythemia after observations of its effect on platelet levels. Subsequently, Step Pharma received an EIC Accelerator award consisting of a €2.5 million grant and potential equity investment up to €10 million, alongside appointing Dr. Karen Smith as Chief Medical Officer.

The funds will advance its lead candidate STP938, a first-in-class therapy targeting CTPS1, into clinical development for T-cell malignancies, with plans to enter the clinic in Q1 2022. Jacob Moresco from Sunstone Life Science Ventures and Walter Stockinger from Hadean Ventures joined the board as part of the financing. Step Pharma aims to transform into a clinical-stage company with this investment, addressing significant unmet needs in T-cell malignancy treatments supported by human genetic data and commercial potential.
