Outcome

Type Measure Description Time frame Safety issue

Secondary Time to CCR (TTCCR) Time from C1D1 to the first recorded CR, CRh or CRi Up to approximately 2 years
Secondary Duration of response (DoR) Time from the first recorded response until disease progression, relapse, or death due to any cause, whichever occurs first Up to approximately 2 years
Secondary Duration of CCR (DoCCR) Time from the first recorded CR, CRh or CRi until disease progression, relapse, or death due to any cause, whichever occurs first Up to approximately 2 years
Secondary Rate of CCR Without Minimal Residual Disease (CCR MRD-) The proportion of subjects achieving CR, CRh or CRi with MRD-negative status per ELN 2022 criteria. Up to approximately 2 years
Secondary Event-free survival (EFS) Time from C1D1 until disease progression, relapse, or death due to any cause, whichever occurs first Up to approximately 2 years
