Best Radiographic Response in Grade IV Glioma Patients. BEV = bevacizumab. The X axis represents the number of doses of pembrolizumab that was received by each patient. The color represents the best radiographic response each patient had. One patient continue on pembrolizumab at the end of data collection. Eleven patients previously progressed on bevacizumab; of those patients 10 continued bevacizumab with pembrolizumab. 2 patients never received bevacizumab and, of those, one started on bevacizumab with pembrolziumab. One patient had a partial response; 3 had stable disease; and the rest had progressive disease
