Cancer Preventive Vaccine Nous-209 for Lynch Syndrome Patients
Active Not Recruiting
This phase Ib/II trial evaluates the safety and effect of the Nous-209 vaccine in Lynch syndrome patients. Lynch syndrome is an inherited disorder in which affected individuals have a higher-than-normal chance of developing colorectal cancer and certain other types of cancer, often before the age of 50. In Lynch syndrome, errors in the genetic information inside cells are not properly corrected. When that happens, the cells produce new proteins called neoantigens. Neoantigens are recognized by t...
