NCT06749925 | NOT YET RECRUITING | Glioblastoma

Clinical Trial Assessing the Efficacy and Safety of Dendritic Cell-Based Immunotherapy for Glioblastoma
Sponsor:

University of Sao Paulo General Hospital

Information provided by (Responsible Party):

Jose Alexandre Marzagão Barbuto

Brief Summary:

This Phase III, multicenter, placebo-controlled clinical trial with sequential randomization is designed to evaluate the efficacy and safety of an experimental vaccine composed of hybrid dendritic cells (DCs) for the treatment of glioblastoma. Conducted at the Hospital das Clínicas of the University of São Paulo Medical School (HCFMUSP) and the Institute of Biomedical Sciences of the University of São Paulo (ICB/USP), the study is led by Professor José Alexandre Marzagão Barbuto. A multidisciplinary team of researchers specializing in neurosurgery, pathology, hematology, and other fields will contribute to a comprehensive approach. The trial aims to determine whether the hybrid DC vaccine can increase overall survival in adult patients with glioblastoma who have completed standard treatment, including surgery, chemotherapy, and radiotherapy. Secondary objectives include evaluating progression-free survival, quality of life, immune response, and the safety of the intervention. The study will enroll 186 patients, who will be randomized into three groups: (1) a control group receiving placebo, (2) a group receiving the DC vaccine, and (3) a group receiving the DC vaccine combined with pembrolizumab.
