Study tests if Two-Drug maintenance beats One-Drug after stem cell transplant for myeloma
NCT ID NCT05271630
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at 69 people with multiple myeloma who had a stem cell transplant. It compares those who take one maintenance drug versus two drugs (an immunomodulatory agent plus a proteasome inhibitor) to see which keeps the cancer away longer. The goal is to learn if the two-drug combo leads to better outcomes, like turning cancer markers from positive to negative.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Immunomodulatory agent and proteasome inhibitor
- What this could lead to
- If successful, this could help doctors choose the best maintenance therapy to keep multiple myeloma in remission longer after a stem cell transplant.
- What could go wrong
- This is an observational study, not a controlled trial, so it cannot prove one treatment is better. Results may not apply to all patients.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * All MM patients (18 years or greater) receiving autologous transplantation given as first line therapy (Melphalan at least 140 mg/m2) will be screened and enrolled in the study if they qualify and willing to participate. * Ability to provide written informed consent obtained prior to participation in the study and any related procedures being performed. * Histologically confirmed diagnosis of multiple myeloma. * Received high dose melphalan (≥ 140 mg/m2) followed by ASCT based on the institutional guidelines and within +60 and +180 after ASCT at the time of maintenance initiation. * Disease status must be very good partial response (VGPR), complete remission (CR), or stringent complete remission (sCR) per IMWG response criteria at time of study entry. * Measurable disease at diagnosis per IMWG criteria serum M spike ≥ 1g/dL, or Urine M protein ≥ 200 mg/24h or involved free light chain ≥ 100 mg/L with an abnormal ratio. * Patients must have the Clonoseq ID sample showing a trackable clone in bone marrow. Exclusion Criteria: * Patients who have purely non-secretory multiple myeloma (i.e., the absence of a measurable protein in serum by electrophoresis and immunofixation and the absence of Bence-Jones protein in the urine defined by use of electrophoresis and immunofixation) * Prior evidence of disease progression * Patients who have other malignancy associated with a high risk of progression in the next 2 years.
