NCI-4650

Background:
Exome sequencing can identify certain gene mutations in a person's tumor. This can then be used to create cancer treatments. In this study, researchers will make a treatment called a messenger ribonucleic acid (mRNA) vaccine. The vaccine might cause certain tumors to shrink.
Objective:
To see if the mRNA vaccine is safe and can cause metastatic melanoma or epithelial tumors to shrink.
Eligibility:
People 18-70 years old with metastatic melanoma or epithelial cancer
Design:
Participants will be screened under protocol 99-C-0128.
Participants will provide samples under protocol 03-C-0277:
Participants will provide a piece of their tumor from a previous surgery or biopsy.
Participants will have leukapheresis: Blood is removed through a needle in one arm and circulated through a machine that takes out the white blood cells. The blood is then returned through a needle in the other arm.
Participants will have many tests:
Scans and x-rays
Heart and lung function tests
Blood and urine tests
Participants will receive the mRNA vaccine every 2 weeks for up to 8 weeks. They will get the vaccine as an injection into the upper arm or thigh. They may receive a second course of vaccines if the study doctor determines it is needed.
Participants will have follow-up visits approximately 2 weeks after their final vaccine, then 1 month later, then every 1-2 months for the first year, and then once a year for up to 5 years. Each visit may take up to 2 days and include:
Physical exam
Blood tests
Scans
Leukapheresis at the first visit
