Roswell Park Cancer Institute is launching a clinical trial to evaluate a cancer vaccine designed to eradicate cancer cells and prevent relapse of disease.
The experimental dendritic cell vaccine, which was developed at Roswell Park, will be manufactured at the cancer center in a custom-made unit that can maintain control of temperature and gases, officials were to announce today.
The immune system protects the body against harmful invaders, such as viruses. Dendritic cells, acting somewhat like messengers, play a key role in this defense mechanism.
Dendritic cells are removed from a patient and stimulated with a specialized protein. The treated cells are then given back to the patient as a vaccine designed to recruit killer immune cells that seek and destroy cancer, Dr. Kunle Odunsi, director of Roswel Park's Center for Immunotherapy and principal investigator, said in a statement.
The new study will test the vaccine in combination with rapamycin, a compound used to prevent rejection of organ transplants. Research at the cancer center indicates that rapamycin prevents the immune system from using up its cancer-killing T-cells in a quick burst.
The study is expected to enroll about 20 patients. The vaccine is being considered for a host of cancers, including ovarian, bladder, brain and breast.
