Dendritic Cell Activating Scaffold in Melanoma

This research study is a Phase I clinical trial. Phase I clinical trials test the safety of investigational melanoma vaccines. Phase I studies also try to define the appropriate dose of the investigational vaccine, in this case WDVAX, to use for further studies. "Investigational" means that the vaccine is still being studied and that research doctors are trying to find out more about it. It also means that the FDA has not yet approved WDVAX for any use in patients, including people with Melanoma. The purpose of this study is to determine if it is possible to make a vaccine against melanoma by using your own melanoma tumor cells and combining them with other proteins which activate the immune system. We hope that by combining the cells and the proteins in this way that the vaccine will cause your own immune system to react against your melanoma tumor cells. The purpose of this study is also to determine the safest way to give this vaccine with the least amount of side effects. Each vaccine will contain your own tumor cells which have been killed by a freezing and thawing process which destroys the cells but keeps the proteins from the melanoma cells. This is called a "tumor lysate" Your tumor lysate is combined with other proteins which activate the immune system. The other proteins are called GM-CSF and CpG. All of this is held together to form a "tablet" or "scaffold" which is about the size of a regular aspirin tablet. The material that holds the protein together is called PLGA. PLGA is the same material that doctors use for "dissolvable stitches" If you have ever had a problem with these types of stitches in the past, be sure to let your study doctor know about this.
