14 out of 18 (78%) patients with measurable disease on the rindopepimut arm experienced any tumor shrinkage versus 9 out of 16 (56%) patients on the control arm. Assessments of response were conducted by study investigators according to RANO criteria. Cases with greater than a 25% reduction in area of measurable disease were also reviewed by an expert panel blinded to treatment assignment.

70% of patients in the rindopepimut arm had stable disease or better for greater than 2 months versus 55% in the control arm. Further emphasizing the benefit in disease control, only 5% of patients treated with rindopepimut required an increase in steroids versus 35% of patients on the control arm.
