Details and patient eligibility

About

This is a phase I clinical trial evaluating the safety, tolerability, and maximum tolerated dose of MSC11FCD, an investigational allogeneic bone marrow-derived mesenchymal stem cell therapy expressing a suicide gene, in patients with newly diagnosed glioblastoma. The investigational product is administered intratumorally following surgical resection. This study aims to explore whether MSC11FCD can provide a targeted, localized treatment option during the postsurgical period, potentially addressing residual tumor cells and reducing early recurrence.

Full description

Glioblastoma is a highly aggressive and rapidly progressing malignant brain tumor classified as a grade IV glioma. Despite the current standard of care, including surgical resection, radiation therapy, chemotherapy, and tumor treating fields, prognosis remains poor due to high recurrence rates, tumor heterogeneity, treatment resistance, and limited drug penetration across the blood-brain barrier. Moreover, glioblastoma often exhibits rapid tumor regrowth during the postsurgical recovery period when few therapeutic options are available.

This study investigates MSC11FCD, an investigational allogeneic bone marrow-derived mesenchymal stem cell product genetically modified to express a suicide gene. The product is administered intratumorally in newly diagnosed glioblastoma patients following surgical resection. The primary objective of the study is to evaluate the safety, tolerability, and maximum tolerated dose of MSC11FCD. Secondary objectives include the assessment of preliminary efficacy signals. The study aims to explore the potential of this novel therapeutic approach to selectively target residual tumor cells and potentially delay or prevent early recurrence, thereby contributing to improved patient outcomes and quality of life.

Exclusion criteria

Patients with recurrent glioblastoma. Known Dihydropyrimidine Dehydrogenase (DPD) deficiency Contraindications to contrast-enhanced MRI (e.g., patients with pacemakers or other reasons preventing MRI scans according to the study schedule)
Patients who received Gliadel wafer implantation during surgery

Pregnant or breastfeeding women, patients planning to become pregnant during the study period, or those unwilling to use appropriate contraception
Participation in another clinical trial within 30 days prior to enrollment
Any condition that, in the opinion of the investigator, would make the patient unsuitable for study participation
