Official title

Phase I Surgical Trial to Evaluate Early Immunologic Pharmacodynamic Parameters for the PD-1 Antibody Pembrolizumab With Autologous Tumor Lysate-Pulsed Dendritic Cell Vaccination in Patients With Surgically Accessible Recurrent/Progressive Glioblastoma

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This phase I trial studies the side effects and how well of pembrolizumab and a vaccine therapy (ATL-DC vaccine) work in treating patients with glioblastoma that has come back (recurrent) and can be removed by surgery (surgically accessible). Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Vaccines, such as ATL-DC vaccine, may help the body build an effective immune response to kill tumor cells. Giving pembrolizumab and ATL-DC vaccine may work better in treating patients with glioblastoma compared to ATL-DC alone.
