Real-World Clinical Outcomes in Patients With Relapsed/Refractory Multiple Myeloma
- Conditions
- Relapsed and Refractory Multiple Myeloma (RRMM)
- Interventions
- Other: Non-Interventional
- Registration Number
- NCT05673967
- Lead Sponsor
- Regeneron Pharmaceuticals
- Brief Summary
Primary Objective:
1. To describe the distribution of treatment regimens and objective response rate (ORR) in a Benchmark Cohort of real-world patients with relapsed/refractory multiple myeloma (RRMM) who initiate treatment after meeting the following criteria: (1) have either (a) at least three prior lines (3L) and are triple-class exposed (TCE), or (b) are triple-class refractory (TCR), and (2) meet similar inclusion/exclusion criteria to patients in phase 2 cohort 2 of the R5458-ONC-1826 (NCT03761108) trial.
Secondary Objectives:
1. To describe additional outcomes (duration of response \[DOR\], progression-free survival \[PFS\], overall survival \[OS\], and time to next treatment \[TTNT\]) in the same Benchmark Cohort population described in the primary objective.
2. To describe distribution of treatment regimens, ORR, DOR, PFS, OS, and to compare ORR, PFS, OS, and TTNT in an Analysis Cohort consisting of real-world patients derived from the Benchmark Cohort described above who are weighted to align with the characteristics of patients in phase 2 cohort 2 of the R5458-ONC-1826 (NCT03761108) trial. Comparative analyses of PFS and OS will be performed conditional on sufficient maturity of survival data in the R5458-ONC-1826 (NCT03761108) trial at the time of analysis.

- Arm && Interventions
Group Intervention Description Cohort 1 Non-Interventional Real-world (RW) patients with RRMM who have either at least three prior lines of therapy (LOT) and are triple-class exposed (3L+/TCE), or are triple-class refractory (TCR), meet similar inclusion/exclusion criteria used to establish phase 2 cohort 2 of the R5458-ONC-1826 trial, and are initiating currently available therapies.
- Primary Outcome Measures
Name Time Method Proportion of patients exposed to each type of regimen by line of therapy (LOT) Up to 6 years Distribution of treatment regimens
Proportion of patients with objective response rate (ORR) Up to 6 years Defined as stringent complete response (sCR), complete response (CR), very good partial response (VGPR), or partial response (PR)
- Secondary Outcome Measures
Name Time Method Duration of response (DOR) Up to 6 years Defined as time from the date of the first documented response (best overall response of sCR, CR, VGPR, PR) until the first date of progressive disease (PD) by International Myeloma Working Group (IMWG) or death due to any cause, whichever occurs first.
Progression-free survival (PFS) Up to 6 years Defined as time from the start of study treatment until the first date of PD by IMWG, or death due to any cause, whichever occurs first.
Time to next treatment (TTNT) Up to 6 years Defined as time from the start of study treatment until the initiation of the subsequent LOT.
Overall survival (OS) Up to 6 years OS is measured from the start of study treatment until death due to any cause.
