About the Study

Lynch Syndrome (LS) increases the risk of colon cancer and other cancers, including cancer of the uterus, ovaries, small bowel, stomach, pancreas, urinary tract, skin, and brain.

This study is being done to assess the safety and effectiveness of a series of vaccines (Tri-Ad5), together with another drug (N-803) that magnifies the body’s response to vaccines, to see if there is an effect on the risk of developing colon and other cancers in LS patients.
