Change From Baseline in European Organization for Research and Treatment of Cancer Quality of Life Cancer Specific Questionnaire With 30 Items (EORTC QLQ-C30): Global Health Status (GHS)/Quality of Life (QOL) Score

EORTC-Quality of Life Questionnaire (QLQ)-C30 is a cancer-specific instrument with 30 questions for evaluation of new chemotherapy and provides an assessment of participant reported outcome dimensions. EORTC QLQ-C30 included GHS/ QOL, functional scales (physical, role, cognitive, emotional, social), symptom scales (fatigue, pain, nausea/vomiting), and 6 single items (dyspnea, appetite loss, insomnia, constipation, diarrhea, financial difficulties). Most questions from QLQ-C30 were a 4-point scale (1/Not at All to 4/Very Much), except Items 29-30, which comprise GHS scale and were a 7-point scale (1/Very Poor to 7/Excellent). Answers were converted into grading scale, with values between 0 and 100. A high score represented a favorable outcome with a best quality of life for participant.

Change From Baseline in European Organization for Research and Treatment of Cancer Quality of Life Multiple Myeloma Specific Module With 20 Items (EORTC QLQ-MY20): Disease Symptoms Domain Score

EORTC QLQ-MY20 is a validated questionnaire to assess the overall quality of life in participants with multiple myeloma. Disease symptoms domain is one of the four domain scores. Disease symptoms domain score used 4-point scale (1 'Not at All' to 4 'Very Much'). Scores are averaged, and transformed to 0 -100 scale, where higher scores = more symptoms and lower health-related quality of life (HRQL) and lower score = less symptoms and more HRQL

Change From Baseline in European Organization for Research and Treatment of Cancer Quality of Life Multiple Myeloma Specific Module With 20 Items (EORTC QLQ-MY20): Side Effects of Treatment Domain Score

EORTC QLQ-MY20 is a validated questionnaire to assess the overall quality of life in participants with multiple myeloma. Side effects of treatment domain is one of the four domain scores. Side effects of treatment domain score used 4-point scale (1 'Not at All' to 4 'Very Much'). Scores are averaged, and transformed to 0-100 scale, where higher scores = more side effects and lower HRQL and lower scores = less side effects and better HRQL.

Change From Baseline in European Quality of Life Working Group Health Status Measure 5 Dimensions (5D), 5 Levels (5L) (EQ-5D-5L) Score: Health State Utility Index Value

The EQ-5D-5L is a standardized measure of health status that provides a general assessment of health and wellbeing. The EQ-5D descriptive system comprises 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has a 5-level response: no problems, slight problems, moderate problems, severe problems, and extreme problems. Response options are measured with a 5-point Likert scale (for the 5L version). The 5D-5L systems are converted into a single index utility score between 0 to 1, where higher score indicates a better health state and lower score indicate worse health state.

Change From Baseline in European Quality of Life Working Group Health Status Measure 5 Dimensions, 5 Levels (EQ-5D-5L) Score: Visual Analogic Scale (VAS)

EQ-5D-5L is a standardized, participant-rated questionnaire to assess health-related quality of life. The EQ-5D-5L includes 2 components: the EQ-5D-5L health state utility index (descriptive system) and the EQ-5D-5L Visual Analog Scale. The Visual Analogue Scale is designed to rate the participant's current health state on a scale from 0 to 100, where 0 represents the worst imaginable health state and 100 represents the best imaginable health state.

Brief Summary

Primary Objective: To demonstrate the benefit of isatuximab in combination with pomalidomide and low-dose dexamethasone in the prolongation of Progression Free Survival (PFS) as compared to pomalidomide and low-dose dexamethasone in participants with refractory or relapsed and refractory multiple myeloma (MM). Secondary Objectives: To evaluate the Overall Response Rate (ORR) as per International Myeloma Working Group (IMWG) criteria in each arm. To compare the Overall Survival (OS) between the two arms. To evaluate the Time To Progression (TTP) in each arm. To evaluate the PFS in high risk cytogenetic population in each arm. To evaluate the Duration of Response (DOR) in each arm. To evaluate the safety in both treatment arms. To determine the Pharmacokinetic profile of isatuximab in combination with pomalidomide. To evaluate the immunogenicity of isatuximab. To assess disease-specific and generic health-related quality of life (HRQL), disease and treatment-related symptoms, health state utility, and health status.

Detailed Description

The duration of the study for the participants included a period for screening of up to 21 days (or up to 28 days for women who can become pregnant). Participants continued study treatment until disease progression, unacceptable adverse reaction, participants' wish or other reason of discontinuation. During follow-up, participants who discontinued the study treatment due to progression of the disease were followed every 3 months (12 weeks) for survival (or until cut-off date), and participants who discontinued the study treatment prior to documentation of disease progression were followed-up every 4 weeks until disease progression, and then every 3 months (12 weeks) for survival (or until cut-off date).
