Cancer remains one of the leading causes of mortality worldwide, with colorectal cancer (CRC) and pancreatic ductal adenocarcinoma (PDAC) representing two major unmet clinical challenges. CRC is among the most common cancers globally, while PDAC is one of the deadliest malignancies, characterized by poor prognosis and resistance to existing therapies. Current treatment options are often limited by severe side effects, therapeutic resistance, and relapse, highlighting the urgent need for safer and more effective therapeutic approaches.
The MEDiCS project addresses this challenge through the development of a new anticancer chemotherapy targeting the respiration of cancer stem cells, based on the ruthenium complex IGN116. Unlike conventional metal-based chemotherapeutics that promote cytotoxic effects, IGN116 interferes with aerobic oxidative phosphorylation (OXPHOS), a bioenergetic pathway that is key for cancer stem cells (CSCs), a population associated with metastasis, therapy resistance, and tumor recurrence.
Preclinical studies have shown that IGN116 can inhibit tumor growth within 1–2 days after treatment in patient-derived xenograft (PDX) models of CRC and PDAC. Importantly, the compound exhibits a favorable toxicity profile, primarily targeting CSC metabolism while largely sparing healthy cells. This represents a novel therapeutic strategy among both organometallic drugs and CSC-targeting therapies, with the potential to be used in combination with current standards of care.
The project currently stands at Technology Readiness Level (TRL) 3–4, with demonstrated in vivo efficacy, a validated mechanism-of-action hypothesis, and completed pharmacokinetic and toxicity studies conducted internally and through external contract research organizations. However, several limitations remain that must be addressed to enable further development. MEDiCS aims to overcome these limitations through the development of nanoformulations of IGN116.
To advance the technology towards TRL5 and future clinical translation, MEDiCS will develop a scalable GMP-compatible manufacturing process, conduct GLP-compatible in vitro and in vivo studies, and establish a dedicated spin-out company to support commercialization and industrial uptake. These activities will prepare the pathway for first-in-human clinical testing in patients with CRC and PDAC.
By delivering a safer and more effective CSC-targeted therapy, MEDiCS aims to improve outcomes for patients with difficult-to-treat cancers while reducing the burden associated with highly toxic anticancer treatments. The project has the potential to benefit a large number of patients with CRC and PDAC and strengthen Europe’s position in the development of innovative anticancer therapeutics.
