Official title

A Phase I/II Trial to Evaluate the Safety and Immunogenicity of a Messenger RNA (mRNA)-Based, Personalized Cancer Vaccine Against Neoantigens Expressed by the Autologous Cancer

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

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
