Design outcomes

Primary

MeasureTime frame
Part 1: Progression-free Survival (PFS) Up to 9 years PFS is defined as the time from the date of randomization to the date of first documented disease progression, as defined in the International myeloma working group (IMWG) 2016 response criteria, or death due to any cause, whichever occurs first. Part 2: Number of Participants Reporting Cytokine Release Syndrome (CRS) Cases by Severity Up to 9 years Severity for CRS will be graded as follows: Grade 1: Fever (Temperature greater than or equal to [>=] 38degrees Celsius); Grade 2: Fever (Temperature >=38degrees Celsius) with either: hypotension and/or hypoxia requiring low-flow nasal cannula or blow-by; Grade 3: Fever (Temperature >=38degrees Celsius) with either: hypotension and/or hypoxia requiring high-flow nasal cannula, facemask, nonrebreather mask, or Venturi mask; Grade 4: Fever (Temperature >=38degrees Celsius) with either: hypotension requiring multiple vasopressors (excluding vasopressin), and/or hypoxia requiring positive pressure and Grade 5: Death.

Secondary

MeasureTime frame
Part 1 and 2: Overall Response (Partial Response [PR] or Better) Up to 9 years Overall response (PR or better) is defined as participants who have a PR or better prior to subsequent antimyeloma therapy in accordance with the IMWG 2016 criteria. Part 1 and 2: Very Good Partial Response (VGPR) or Better Response Up to 9 years VGPR or better (Stringent Complete Response [sCR]+Complete Response [CR]+VGPR) is defined as participants who achieve a VGPR or better response prior to subsequent antimyeloma therapy in accordance with the IMWG 2016 criteria. Part 1 and 2: Complete Response (CR) or Better Response Up to 9 years CR or better response is defined as participants who achieve a CR or better response prior to subsequent antimyeloma therapy in accordance with the IMWG 2016 criteria. Part 1: Duration of Response (DOR) Up to 9 years DOR is defined as the time interval between the date of initial documentation of a response (PR or better) to the date of first documented evidence of progressive disease according to the IMWG 2016 response criteria or death due to any cause, whichever occurs first. Part 1: Time to Next Treatment (TTNT) Up to 9 years TTNT is defined as the time from randomization to the start of subsequent antimyeloma treatment. Part 1: Progression-free Survival on Next-line Therapy (PFS2) Up to 9 years PFS2 is defined as the time interval between the date of randomization and date of event, which is defined as progressive disease as assessed by investigator on the first subsequent line of antimyeloma therapy, or death from any cause, whichever occurs first. Part 1: Overall Survival (OS) Up to 9 years OS is defined as the time from the date of randomization to the date of the participant's death due to any cause. Part 1 and 2: Number of Participants with Adverse Events (AEs) by Severity Up to 9 years Number of participants with AEs by Severity will be reported. Part 1 and 2: Number of Participants with Serious Adverse Events (SAEs) by Severity Up to 9
