Outcomes

Primary Outcomes

Overall Response

Overall response is defined as having achieved partial response (PR) or better, according to the international myeloma working group (IMWG) response criteria, as assessed any time after first administration of study treatment, but prior to progression of disease (PD) or subsequent antimyeloma therapy.

Time frame: Up to 5 years and 7 months

Progression-Free Survival (PFS)

PFS is defined as the duration from the date of randomization to either progressive disease (PD) or death, whichever comes first. Disease progression will be determined according to the IMWG response criteria.

Time frame: Up to 5 years and 7 months

Secondary Outcomes

Very Good Partial Response (VGPR) or Better

VGPR or better is defined as achieving VGPR, complete response (CR), or stringent complete response (sCR) in accordance with the IMWG criteria during or after the study treatment but prior to subsequent antimyeloma therapy.

Time frame: Up to 5 years and 7 months

Complete Response (CR) or Better

CR or better is defined as achieving CR or sCR in accordance with the IMWG criteria during or after the study treatment but prior to subsequent antimyeloma therapy.

Time frame: Up to 5 years and 7 months

Duration of Response (DoR)

DoR is defined as the time interval between the date of initial documentation of a response (partial response \[PR\] or better) to the date of first documented evidence of progressive disease according to the IMWG response criteria or death due to any cause, whichever occurs first.

Time frame: Up to 5 years and 7 months

MRD-negative CR is defined as the participants who achieve MRD-negative status, as determined by next-generation flow cytometry (NGF), at any time point after the date of randomization and prior to PD or subsequent antimyeloma therapy. Additionally, participants must achieve CR or better, according to IMWG response criteria at any time from the date of randomization and within 3 months after achieving MRD negative status, prior to PD or subsequent antimyeloma therapy.

Time frame: Up to 5 years and 7 months

MRD-Negative CR at 12 months

MRD-negative CR at 12 months is defined as the participants who achieve MRD-negative status at the analysis time window of 12 months (+/-3 months) from the date of randomization, as determined by NGF prior to PD or subsequent anti-myeloma therapy. Additionally, participants must also achieve CR or better, according to IMWG criteria at any time from the date of randomization up to and including 12 months (+/-3 months), prior to PD or subsequent antimyeloma therapy.

Time frame: 12 months

Sustained MRD-negative CR

Sustained MRD-negative CR is defined as participants who achieve MRD-negative CR status, as determined by NGF, for at least 12 months without any examination showing MRD-positive status and prior to PD or subsequent anti-myeloma therapy.

Time frame: Up to 5 years and 7 months

Progression-Free Survival on the First Subsequent Line of Antimyeloma Therapy (PFS2)

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. Those who are alive and for whom a second disease progression has not been observed are censored at the last date of follow-up.

Time frame: Up to 5 years and 7 months

Overall Survival (OS)

OS is defined as the time from the date of randomization to the date of the participant's death due to any cause.

Time frame: Up to 5 years and 7 months

Time to Subsequent Anti-Myeloma Therapy

Time to subsequent anti-myeloma therapy is defined as the time from randomization to the start of subsequent antimyeloma treatment. Death due to progressive disease without the start of any subsequent antimyeloma therapy will be considered as an event.

Time frame: Up to 5 years and 7 months

Number of Participants With Treatment-Emergent Adverse Events (TEAE) by Severity

An AE is any untoward medical occurrence in a clinical study participant administered a pharmaceutical (investigational or non investigational) product. An AE does not necessarily have a causal relationship with the treatment. Any new or worsening AE occurring at or after the initial administration of study treatment through the day of last dose plus 30 days or prior to the start of subsequent anticancer therapy, whichever is earlier, or any follow-up AE with onset date and time beyond 30 days after the last dose of study treatment but prior to the start of subsequent therapy or any AE that is considered treatment-related regardless of the start date of the event is considered to be treatment-emergent. TEAEs will be graded according to the National Cancer Institute-Common Terminology Criteria for Adverse Events (NCI-CTCAE) Version 6.0. Severity scale ranges from Grade 1= mild, Grade 2= moderate, Grade 3= severe, Grade 4= life-threatening, to Grade 5= death related to adverse event.

Time frame: Up to 5 years and 7 months

Number of Participants with Abnormalities in Clinical Laboratories Results

Number of participants with abnormalities in clinical laboratories results (serum chemistry and hematology) will be reported.

Time frame: Up to 5 years and 7 months
