Imagine a new beacon of hope for those battling severe blood cancers. ExCellThera’s innovative Zemcelpro cell therapy just secured European authorization, promising a crucial treatment for patients without compatible donor cells. This breakthrough is set to transform transplant options and offer renewed hope. How will this life-changing therapy impact patients across the continent?

ExCellThera has achieved a monumental milestone with the conditional marketing authorization from the European Commission (EC) for its groundbreaking Zemcelpro cell therapy. This critical approval ushers in a new era of hope for blood cancer patients, particularly those who have exhausted conventional options due to the absence of suitable donor cells. It signifies a profound advancement in the fight against life-threatening hematological malignancies, offering a novel therapeutic pathway where none existed before.

This landmark authorization by the European Commission extends the reach of Zemcelpro across all European Union (EU) member states, alongside Iceland, Norway, and Liechtenstein. The broad geographical scope of this approval ensures that a significant population of patients in urgent need will now potentially gain access to this innovative treatment, underscoring the collaborative efforts between regulatory bodies and pharmaceutical innovators.

Zemcelpro, also known as UM171 Cell Therapy, represents a sophisticated medical advancement. It meticulously combines UM171-expanded CD34+ cells with unexpanded CD34- cells, both meticulously derived from a single cord blood unit. This unique composition is specifically engineered to provide a viable transplant option for individuals facing severe blood cancers who are otherwise left without suitable donor cells, addressing a critical unmet medical need.

David Millette, the esteemed CEO of both ExCellThera and Cordex Biologics, underscored the profound impact of this authorization. “This authorisation marks a pivotal milestone in delivering on the therapeutic promise of Zemcelpro for adults battling life-threatening haematological malignancies,” Millette stated, emphasizing the company’s commitment to transforming patient outcomes through cutting-edge cell therapy research and development.

Millette further highlighted the unparalleled position of Zemcelpro in the medical landscape, describing it as “the first and only cell therapy approved for patients without access to suitable donor cells.” This distinct attribute positions Zemcelpro as a vital new stem cell transplant option, not merely a treatment, but a renewed source of hope for countless individuals and families who previously had no viable recourse.

The EC’s decision followed a robust and positive recommendation from the European Medicines Agency’s (EMA) Committee for Medicinal Products for Human Use (CHMP) in June 2025. The committee’s endorsement was firmly rooted in compelling evidence from two Phase II clinical studies, which conclusively demonstrated Zemcelpro’s ability to induce both neutrophil and platelet engraftment, critical indicators of successful transplantation.

While the future availability of Zemcelpro will be contingent upon national reimbursement outcomes across various European countries, the scientific community eagerly anticipates its broader implementation. ExCellThera has also announced plans for a crucial Phase III trial, specifically targeting patients with high-risk blood cancers and myelodysplasias. Importantly, the safety profile of Zemcelpro has been found to align favorably with that of conventional allogeneic stem cell transplantation methods, reassuring both clinicians and patients.

This significant approval for Zemcelpro underscores the burgeoning momentum within the broader cell and gene therapy industry. These innovative therapies are rapidly transforming the landscape of disease treatment, promising not just management but potential cures for a wide array of conditions.
