Addressing pediatric diseases at their root.
About Genewity

A single genetic defect can have a serious impact on a child’s life. For example, children with Severe Combined Immunodeficiency (SCID) are born without a functioning immune system. Even minor infections can become life-threatening, and without treatment, many do not survive their first year. Such severe conditions are rare, but for families affected, the diagnosis is heartbreaking and marks the start of a difficult and uncertain journey.
At Genewity, we develop pioneering stem cell-based gene therapies that target the root cause of these diseases. Our clinical-stage program (executed by subsidiary Videja) has already demonstrated the potential for one-time, durable treatments. We are advancing a pipeline of therapies aimed at transforming the lives of children with severe unmet medical needs.

Mission
Developing one-time treatments for life-threatening rare pediatric diseases
Vision
Unlocking the unrealized potential of autologous ex vivo stem cell gene therapy
Technology
Our therapies use a patient’s own bone marrow stem cells that are genetically modified outside the body to by inserting a functional copy of the defect gene. Once returned and infused into the patient, these cells repopulate the bone marrow and restore the function of the corrected gene, addressing the root cause of the disease.
The process leverages the well-established logistics of stem cell transplantation. Patients’ bone marrow cells are collected locally, shipped to specialized facilities for the gene insertion, and returned for infusion in a hospital near home. Building on this infrastructure, children can receive this therapy in a local hospital. This way we can minimize disruption for families while maintaining the highest standards of quality and care.
The correction of genes in bonw marrow stem cells offers the possibility of a durable, one-time treatment, providing long-lasting benefit and addressing the disease at its root.
Key advantages of our approach
Targeted: Focused on the underlying genetic defect.
Durable: One-time therapy with potential for life-long benefit.
Patient-centered: Cells travel, not the patient.
Versatile technology: Applicable to multiple severe children’s diseases.
Our clinical-stage programis already demonstrating the power of its platform technology. Early results inpatients with Recombinase 1-Activating Gene 1 (RAG1)-SCID have been highly encouraging, with children showing restored immune function and thriving development, giving them the opportunity to live healthy, normal lives. Building on this success, Genewity plans to expand the approach to treat other genetic disorders, offering the promise of durable, one-time therapies that address the root cause of disease.

Genewity Holding B.V. is a biotechnology company based at the Leiden Bioscience Park, the Netherlands, specializing in the development of advanced treatments using ex vivo stem cell gene therapy. Genewity holds multiple licenses provided by Dutch University Medical Centers, and based upon those licenses executes a research program (also cooperating in several academic cooperations and European research grants) as well as a clinical trial managed by our subsidiary Videja. We make sure that the results of our research program benefits our clinical activities, but also ascertain that the clinical activities remain separated from the research activities to manage and contain potential conflicts.
