Outcome Measures
Primary Outcomes (2)
Incidence of Dose Limiting Toxicities (DLT)(Safety run-in Patients Only)
A dose-limiting toxicity (DLT) is defined as an adverse event or abnormal laboratory value considered by the Investigator to be at least possibily related to MBG453 as a single contributor or in combination with other component(s) of study treatment that occurs during the DLT observation period and meets any of the criteria as per protolcol.
From Cycle 1 Day 8 to end of Cycle 2; Cycle =28 Days
Percentage of Participants Achieving Complete Remission (CR) (CR Rate)
CR rate is defined as the percentage of participants achieving a complete remission (CR) as per investigator assessment (based on IWG Cheson et al 2003, ELN 2017 Dohner et al 2017).
approx. 31 months
Secondary Outcomes (14)
Measurable Residual Disease (MRD) - Negativity Rate: Full Study Population
approx. 31 months
Measurable Residual Disease (MRD) - Negativity Rate in Participants With Best Overall Response (BOR) of CR/CRi and Evaluable MRD
