The study involves research about MGA271 in combination with Keytruda. MGA271 targets cancer cells that make a lot of a protein called B7-H3. Another way to say it is that the cells "overexpress" the protein. Very few normal cells express B7-H3. MGA271 is though to work by recognizing cancer cells that overexpress B7-H3 and directing the body's immune…
The purpose of this study is to test two imaging techniques, one called whole body diffusion weighted magnetic resonance imaging (WB-DWI MRI), and another called F-18 3-deoxy-3-fluorothymidine PET (F-18-FLT PET). The goal is to see whether these imaging techniques would allow the study doctors to see changes in the size of a tumor earlier for patients with…
