Limb-Girdle Muscular Dystrophy clinical trials at University of California Health

This phase 2 trial tests the safety and effectiveness of a cancer vaccine called LabVax 3(22)-23 and GM-CSF in combination with pembrolizumab in treating adenocarcinoma that has spread to other places in the body (advanced stage). LabVax 3(22)-23 is designed to target a specific antigen (labyrinthin), which is a protein found on the surface of adenocarcinoma tumor cells. Labyrinthin is a protein that is not expressed on normal cells in the skin, lungs, salivary glands, pancreas, nor other tissues. In adenocarcinoma, the tumor cells produce too much labyrinthin causing them to express this protein on the surface of the tumor cells. One way to control the growth of these tumor cells is to teach the immune system to generate an immune response against the labyrinthin protein by vaccination against labyrinthin. GM-CSF, or sargramostim, is a protein that acts as a white blood cell growth factor. It has also been shown to stimulate immune system. Thus, administration of GM-CSF may help to boost the immune system response when given together with the vaccine. This study may improve the general knowledge about LabVax 3(22)-23 and how the body may generate an immune response to kill adenocarcinoma tumor cells. In the second phase of the study, participants will also receive pembrolizumab, which may improve anti-cancer activity when given with LabVax 3(22)-23 and GM-CSF.
