Comparing fixed duration and continuous daratumumab treatment for older adults with multiple myeloma

Official title: A Phase III Non-Inferiority Randomized Controlled Trial of Fixed Duration Versus Continuous Anti-CD38 Antibody Therapy Among Transplant Ineligible Older Adults With Newly-Diagnosed Multiple Myeloma

Run by Canadian Cancer Trials Group · NCT06182774 · Data updated 2026-11-12

This study is testing if older adults with newly diagnosed multiple myeloma can stop daratumumab treatment after 18-20 cycles and still get similar benefits as those who keep taking it continuously.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are older adults with newly diagnosed multiple myeloma who are not eligible for stem cell transplantation and have shown a partial response to initial treatment.

Probably not a fit

Patients who are not newly diagnosed, those who are eligible for stem cell transplantation, or those who have not responded adequately to initial treatment may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial investigates whether stopping daratumumab treatment after 18-20 cycles is as effective as continuous treatment in older adults with newly diagnosed multiple myeloma who are not eligible for a stem cell transplant. Participants will be randomly assigned to either continue their current treatment regimen or stop daratumumab while continuing with lenalidomide and dexamethasone. The goal is to determine if a fixed duration of daratumumab can provide similar benefits without the need for continuous administration. The study aims to enhance treatment strategies for this patient population.

Why it matters

Potential benefit: If successful, this study could lead to a more manageable treatment regimen for older adults with multiple myeloma, potentially reducing side effects and healthcare costs.

How similar studies have gone: While the approach of fixed duration treatment is being explored, this specific comparison of daratumumab treatment duration has not been extensively tested in prior studies.

Inclusion Criteria:

* Participants with newly diagnosed multiple myeloma that are transplant-ineligible
* Measurable disease at the time of diagnosis, as defined by at least one of the following criteria: Serum monoclonal protein (M-protein) ≥ 5 g/L; Urine M-protein ≥ 200 mg/24 hours; Involved serum free light chain measurement ≥ 100 mg/L, provided serum FLC ration is abnormal; For IgA patients whose disease can only be reliably measured by serum quantitative immunoglobulin ≥ 750 mg/dL
* Completed 18-20 cycles of daratumumab-lenalidomide-dexamethasone or isatuximab-lenalidomide-dexamethasone.
* Obtained at least a partial response per the standard 2016 IMWG criteria
* ECOG performance status 0-3
* Participant is able (i.e. sufficiently fluent) and willing to complete the quality of life and/or health utility questionnaires in English, French, or a provided validated language.
* Participant consent must be appropriately obtained in accordance with applicable local and regulatory requirements.
* Participants must be accessible for treatment and follow-up.
* In accordance with CCTG policy, protocol treatment is to begin within 2 working days of participant enrollment.
