What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Major pathological response (MPR) rate
Time Frame: Up to approximately 12 weeks
Up to approximately 12 weeks
Clinical downgrading rate
Time Frame: Up to approximately 12 weeks
