Observed concentration before dosing (Cthrough) at steady state [Time frame for evaluation: Predose at Cycle 6 Day 1 (duration of each cycle is 28 days)] Observed Isatuximab plasma concentration. |
---|---|
Secondary Outcome | 1. Very Good Partial Response or better rate (VGPR) [Time Frame: Up to approximately 2 years] VGPR or better rate defined as the proportion of participants with stringent complete response (sCR), complete response (CR) and very good partial response (VGPR) according to the 2016 International Myeloma Working Group (IMWG) criteria assessed by Independent Review Committee (IRC) 2. Observed concentration before dosing (Ctrough) [Time Frame: At 4 weeks i.e., predose at Cycle 2 Day 1 (duration of each cycle is 28 days)] Observed Isatuximab plasma concentration 3. Incidence rate of infusion-reactions [Time Frame: *] Proportion of participants with infusion-reactions related events 4. Percentage of participants satisfied or very satisfied with the injection method used to administer study medication [Time Frame: At Cycle 5 Day 15] Participant's satisfaction with isatuximab subcutaneous (SC) and intravenous (IV) will be assessed based on the Patient Experience and Satisfaction Questionnaires (PESQ) questionnaire 5. Duration of response (DOR) [Time Frame: Up to approximately 2 years] DOR, defined as the time from the date of the first confirmed response to the date of first occurrence of progressive disease (PD) as determined by IRC or death, whichever happens first. DOR is determined only for participants who have achieved a response (PR or better). In the absence of PD or death before the analysis cut-off date, the DOR will be censored at the date of the last valid disease assessment performed prior to initiation of a further anti-myeloma treatment or the analysis cut-off date, whichever is earlier. Participants with two or more consecutive missed assessments prior to PD or death will be censored at the last valid disease assessment 6. Time to first response (TT1R) [Time Frame: Up to approximately 2 years ] TT1R, defined as the time from randomization to the date of first IRC determined response (PR or better) that is subsequently confirmed. Same censoring rule applies as in the DOR endpoint 7. Time to best response (TTBR) [Time Frame: Up to approximately 2 years ] TTBR, defined as the time from randomization to the date of first occurrence of IRC determined best overall response (PR or better) that is subsequently confirmed. Same censoring rule applies as in the DOR endpoint 8. Progression free survival (PFS) [Time Frame: *] PFS, defined as the time from the date of randomization to the date of first documentation of progressive disease as determined by IRC or the date of death from any cause, whichever comes first. Responses will be determined according to IMWG criteria. Progression based on paraprotein will be confirmed based on two consecutive assessments. PFS will be censored at the date of the last valid disease assessment not showing disease progression performed prior to initiation of a further anti-myeloma treatment (if any) or the analysis cut-off date, whichever comes first. Participants with two or more consecutive missed assessments prior to PD or death will be censored at the last valid disease assessment 9. Overall survival (OS) [Time Frame: *] OS, defined as the time from the date of randomization to death from any cause. Participants without death prior to the analysis cut-off date will be censored at the last date the participant was known to be alive or the cut-off date, whichever is first 10. Progression free survival 2 (PFS2) [Time Frame: *] PFS2, defined as time from the date of randomization to the date of first documentation of PD after initiation of further anti-myeloma treatment or death from any cause, whichever happens first. Same censoring rule applies as in the PFS endpoint 11. Number of participants with treatment-emergent adverse events (TEAEs)/serious adverse events (SAEs). [Time Frame: *] TEAEs are defined as adverse events (AEs) that develop, worsen, or become serious during the treatment period. The treatment period is defined as the time from first dose of study treatment up to 30 days after last dose of study treatment 12. Pharmacokinetic (PK) parameter [Time Frame: *] Maximum plasma concentration (Cmax) 13. PK parameter [Time Frame: *] Area under the plasma concentration time curve over the dosing period (AUC) 14.

Participant expectation questionnaire-baseline (PEQ-BL) score [Time Frame: Cycle 1 Day 1 ((duration of each cycle is 28 days)] PEQ-BL is designed to assess the expectations of the participants regarding both the treatment (side effects, worth taking) and the administration method (confidence, comfortability, pain, side effects, potential time-savings), as well as to understand previous treatment experience from the participant (experience with injection methods for oncology medication) 17. Patient experience and satisfaction questionnaire- follow up (PESQ-FU) score [Time Frame: *] PESQ-FU, a 9-item questionnaire is designed to follow up on participant experience and satisfaction regarding the treatment (side effects, worth taking and overall satisfaction) and the administration method (confidence, comfortability, pain, side effects, potential time-savings and overall satisfaction) 18. Patient experience and satisfaction questionnaire-end of treatment (PESQ-EOT) score [Time Frame: *] PESQ-EOT, a 17-item questionnaire is designed to assess participant experience and satisfaction regarding the treatment (side effects, worth taking and overall satisfaction) and the administration method (confidence, comfortability, pain, side effects, potential time-savings and overall satisfaction). 19. Patient's Assessment of Treatment (PAT) questionnaire score [Time Frame: *] The PAT provides patient insights on the benefits and disadvantages of treatment, including an overall Benefit/Disadvantage ratio using a final question that provides a quantitative assessment of the patient's perceived B/D. 20. Change from baseline in the Health Resource Utilization and Productivity Questionnaire (HRUPQ) scores [Time Frame: Baseline; up to approximately 4 years] Medical resource utilization and participant productivity will be collected from participants through the HRUPQ questionnaire. 21.
