The aim of the ELEVATE trial is to determine the activity and safety of maintenance TMZ dosing followed by nivolumab treatment to evaluate the potential for a future randomised trial against a standard of care control arm. The rationale to continue TMZ for 3 months or until PD is to evaluate the emergence of mismatch repair deficiency both with and without radiological PD, as clinically relevant MMRd may emerge before radiological progression. This will also reduce the number of patients who drop out due to symptomatic progressive disease.
