A Study Comparing Anitocabtagene Autoleucel to Standard of Care Therapy in Participants With Relapsed/ Refractory Multiple Myeloma (iMMagine-3)

A Phase 3, Randomized, Open-Label Study to Compare the Efficacy and Safety of Anitocabtagene Autoleucel Versus Standard of Care Therapy in Participants With Relapsed/Refractory Multiple Myeloma

The goal of this study (iMMagine-3) is to compare the study drug, anitocabtagene autoleucel to standard of care therapy (SOCT) in participants with relapsed/refractory multiple myeloma who have received 1 to 3 prior lines of therapy, including an anti-CD38 monoclonal antibody and an immunomodulatory drug.

The primary objective of this study is to compare the efficacy of anitocabtagene autoleucel versus SOCT in participants with RRMM.

Study Overview

• Status: Recruiting
• Conditions: Multiple Myeloma
• Intervention / Treatment: Drug: Cyclophosphamide; Drug: Fludarabine; Drug: Anitocabtagene Autoleucel; Drug: Pomalidomide; Drug: Bortezomib; Drug: Dexamethasone; Drug: Daratumumab; Drug: Carfilzomib

Detailed Description

After completing the treatment period, all participants who will receive anitocabtagene autoleucel, will be followed in the post-treatment follow-up period. Thereafter, participants will transition to a separate long-term follow-up study (KT-US-982-5968) to continue follow-up out to 15 years.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Progression-Free Survival (PFS)	PFS is defined as the time from randomization to disease progression per International Myeloma Working Group (IMWG) criteria as determined by independent review committee (IRC), or death due to any cause, whichever occurs first.	Up to 4 years
Minimal Residual Disease (MRD) Complete Response (CR) Rate at 9 Months	Minimal MRD is defined as the proportion of participants achieving CR/stringent CR (sCR) and MRD-negative status at 9 months. MRD negativity at 9 months is defined as negative MRD value at 9 months (± 3 months) in bone marrow assessment (< 1 in 105 nucleated cells per IMWG criteria using NGS) (Kumar 2016). CR/sCR per IMWG criteria is determined by IRC.	Up to 9 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Overall survival (OS)	OS is defined as the time from randomization to death due to any cause.	Up to 7 years
Overall Response Rate (ORR)	ORR is defined as the proportion of participants who achieve a best overall response of at least partial response (PR) or better (sCR, CR, very good partial response (VGPR), or PR) per IMWG criteria.	Up to 7 years
MRD-negative CR/sCR	MRD-negative CR/sCR is defined as the proportion of participants achieving MRD-negative CR/sCR until disease progression, subsequent anti-MM therapy, or death.	Up to 7 years
MRD-negative VGPR+	MRD-negative VGPR+ is defined as the proportion of participants achieving MRD negativity and sCR/CR/VGPR until disease progression, subsequent anti-MM therapy, or death.	Up to 7 years
Sustained MRD Negativity	Sustained MRD negativity is defined as the proportion of participants remaining MRD-negative at the 10^-5 sensitivity threshold for the specified number of months starting from the first MRD-negative assessment date to the last MRD-negative assessment date prior to disease progression, subsequent anti-MM therapy, or death. Duration may include ≥ 12 months. Sustained MRD negativity will be evaluated for overall MRD negativity, MRD-negative CR/sCR, and MRD-negative VGPR+.	Up to 7 years
Duration of Response (DOR)	DOR is derived only among participants who experience an overall response (sCR, CR, VGPR, or PR) per IMWG criteria and is defined as the time from first overall response to disease progression per IMWG criteria, or death from any cause, whichever occurs first.	Up to 7 years
Time to Progression	Time to progression is defined as the time from randomization to the first documented disease progression per IMWG criteria, or death due to disease progression, whichever occurs first.	Up to 7 years
Time to Next Treatment	Time to next treatment is defined as the time from randomization to the start of subsequent anti-MM therapy or death from any cause, whichever occurs first.	Up to 7 years
Percentage of Participants Experiencing Treatment-emergent Adverse Events (TEAEs)		First dose up to 7 years
Percentage of Participants With Anti-Anitocabtagene Autoleucel CAR Antibodies (Anitocabtagene Autoleucel Arm)		Up to 7 years
Percentage of Participants With Presence of Replication-Competent Lentivirus (Anitocabtagene Autoleucel Arm)		Up to 7 years
Change From Baseline in the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) Score	The EORTC-QLQ-C30 is a multi-item questionnaire measuring the following content: five (5) multi-item functional scales, three (3) multi-item symptom scales, six (6) single item symptoms scales, one (1) global health status scale, and one (1) global health-related quality of life (HRQoL). Each scale is measured from 0 to 100 after a linear transformation. Higher scores for functioning scales and for the Global Health Status or Global HRQoL scales indicate a higher level of functioning and a better HRQoL respectively, whereas higher scores in symptom scales represent a high level of symptoms.	Up to 7 years
Change From Baseline in the EORTC - Multiple Myeloma Module (EORTC QLQ-MY20) Score	The EORTC QLQ-MY20 has 20 items across 4 independent subscales; 2 functional subscales (body image, future perspective), and 2 symptoms scales (disease symptoms, and side effects of treatment) with a recall period of one week. Scores from each subscale are transformed from 0 to 100. For the functional scales, high scores represent improvement. For the symptom scales, higher scores represent worsening.	Up to 7 years
Change From Baseline in the European Quality of Life 5-Dimension 5-Level Scale (EQ-5D-5L) Score	The EQ-5D-5L questionnaire is a generic measure of health status that provides a simple descriptive profile and a single index value. The EQ-5D-5L comprises 2 components: a questionnaire covering 5 dimensions and a tariff of values based upon direct valuations of health states using a visual analog scale (VAS). The total score for EQ-5D-5L index is presented on a range where higher scores indicate better outcome. A positive change from Baseline indicates improvement.	Up to 7 years
