ImmunoCellular Therapeutics is targeting six proteins that are found on the surface of cancer stem cells in glioblastoma, a brain cancer. Immune cells from the patient’s own immune system are exposed to fragments of these cancer cell proteins in the lab. When returned to the patient’s body, these immune system cells can now help the patient’s immune system identify, and then hopefully kill, the cancer stem cells responsible for the tumor’s recurrence and growth. This Phase 3 trial was suspended in June 2017 due to lack of sufficient financial resources.
