10.Progression free survival (PFS)
[Time Frame baseline:18 months after LPI i.e., approximately 28 months]
PFS defined as time from the date of randomization to the date of first documentation of PD as determined by IRC or the date of death from any cause, whichever comes first.
11.Overall survival (OS)
[Time Frame baseline:18 months after LPI i.e., approximately 28 months]
OS defined as time from the date of randomization to death from any cause
12.Incidence of participants with anti-drug antibodies (ADA) against isatuximab
[Time Frame baseline:From Cycle 1 Day 1 to follow-up (90 days from last administration) i.e., approximately 13 months (1 Cycle = 28 days)]
13.Patient Expectations Questionnaire at Baseline (PEQ-BL v2) with isatuximab administered subcutaneously
[Time Frame baseline:Baseline]
PEQ-BL v2 is a participant assessed questionnaire. It will be completed at baseline prior to study treatment administration or other study related procedures. This questionnaire has been 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).
14.Patient experience and satisfaction questionnaires (PESQ v2) with isatuximab administered subcutaneously
[Time Frame baseline:18 months after LPI i.e., approximately 28 months]
PESQ v2 is a participant assessed questionnaire. It has been 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). The PESQ v2 includes items to assess preference on subcutaneous injection method. This questionnaire has been developed using industry standard for instrument development and has been debriefed and adapted based on qualitative interviews with oncology patients. The more general treatment expectations instrument (v1) was further adapted and debriefed with patients to assess manual and OBDS subcutaneous delivery (v2). The PESQ v2 contains a total of 9 items. There are 6 items that are administered for the duration of treatment, and 3 preference items administered only after patient experience of both manual and OBDS.
15.Health state utility assessed using Health Resource Utilization and Productivity Questionnaire (HRUPQ)
[Time Frame baseline:18 months after LPI i.e., approximately 28 months]
Medical resource utilization and participant productivity will be collected from participants through a specific questionnaire developed by Sanofi. The data collected include number, nature (emergency or routine) and duration of hospitalizations, emergency room visits and outpatient medical encounters and employment history.
16.Health Related Quality of Life (HRQL)
[Time Frame baseline:18 months after LPI i.e., approximately 28 months]
HRQL is assessed using the European Organization for Research and Treatment of Cancer (EORTC) myeloma module with 20 items (QLQ-MY20) and EORTC quality of life questionnaire with 30 questions (QLQ-C30); a total of 50 items. The EORTC QLQ-C30 provides a comprehensive assessment of the principal HRQL dimensions identified as relevant by cancer patients. The EORTC QLQ-MY20 is to be used in conjunction with the EORTC QLQ-C30 to assess symptoms and side effects due to the treatment or the disease which impact HRQL in participants with MM.
17.European Quality of Life Group questionnaire with 5 dimensions and 5 levels per dimension (EQ-5D-5L)
[Time Frame baseline:18 months after LPI i.e., approximately 28 months]
Health status is assessed using the EQ-5D-5L, a standardized measure of health status that provides a simple, generic measure of health utility, and consists of 2 sections: descriptive and VAS. The descriptive system consists of 5 dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. The VAS records the respondent's self-rated health on a 20 cm vertical VAS with endpoints labelled "the best health you can imagine" and "the worst health you can imagine". This information can be used as a quantitative measure of health as judged by the individual respondents.
