p53 Genetic Vaccine(NCI)

Background:
* The p53 gene normally helps to stop cancer cells from growing. However, when the p53 gene is mutated or damaged, cancer cells may grow unchecked. Researchers have been working on a vaccine that will help the immune system recognize and destroy cells that have the p53 mutation and may be cancerous.
* CT-011 is another drug that may help the body's immune system to fight cancer. This drug blocks a chemical found on tumor cells that prevents the immune system from recognizing and destroying them. Research studies have shown that CT-011 slows the growth of tumors. By combining the p53 vaccine and CT-011, researchers hope to slow or stop tumor growth in people whose cancer that has not responded to standard treatments.
Objectives:
- To test the safety and effectiveness of CT-011 and the p53 genetic vaccine to treat adults with solid tumors that have not responded to standard treatments.
Eligibility:
- People at least 18 years of age who have solid tumors that have not responded to standard treatments.
Design:
* Participants will be screened with a medical history and physical exam. They will also have blood tests and tumor imaging studies.
* Participants will receive the p53 vaccine as an injection in the arm or thigh.
* Two days after receiving the p53 vaccine, those in the study will receive CT-011 as an infusion over about 2 hours. Participants will be monitored during the infusion for any side effects.
* The combination of p53 vaccine and CT-011 will be repeated every 3 weeks (one cycle). Treatment will continue as long as the side effects are not severe and the tumor does not grow.
* Three weeks after the second dose of p53 vaccine and CT-011, participants will have a full physical exam. They will also have blood tests, and tumor imaging studies. This exam set will be repeated after every two cycles of p53 vaccine and CT-011.
* Participants will have regular follow-up visits for up to a year after stopping treatment.
