About this study

Official title: Evaluating Mechanisms of Immunomodulator Sensitivity and Resistance in Multiple Myeloma

This phase II trial studies the effect of immunomodulatory drug(s) in combination with a corticosteroid drug in treating patients with multiple myeloma or smoldering multiple myeloma. Immunomodulatory drugs such as lenalidomide and pomalidomide work through a variety of mechanisms to affect the function of the immune system. They are widely used as treatment for multiple myeloma and remain the backbone of therapy for both newly diagnosed patients and patients that have multiple myeloma that has come back after treatment (relapsed). Corticosteroid drugs like dexamethasone are strong anti-inflammatory agents that are also widely used to treat patients with multiple myeloma. This study may help doctors find out how patients respond to one treatment cycle of immunomodulatory drug(s) in combination with dexamethasone. This may help doctors determine which combinations of drugs work best in treating patients with multiple myeloma or smoldering multiple myeloma.

Read the detailed description

PRIMARY OBJECTIVE:

  1. To determine response rates (>= partial response [PR]) of prospectively treated multiple myeloma (MM) patients with one cycle of therapy containing a combination of an immunomodulator and dexamethasone.

SECONDARY OBJECTIVE:

  1. To compare response rates of MM among African-Americans (AA) and white patients to a combination of an immunomodulator and dexamethasone.

II. To establish correlation of biomarkers in treated MM patients with the combination of an immunomodulator and dexamethasone to the depth of hematological response observed in new or previously treated patients.

CORRELATIVE OBJECTIVE:

  1. To identify biomarkers that predict response rates of untreated smoldering MM and MM patients to a combination of an immunomodulator and dexamethasone.

OUTLINE: Patients are assigned to 1 of 4 cohorts.

COHORT A: Patients with smoldering multiple myeloma receive lenalidomide orally (PO) once daily (QD) alone on days 1-14 OR in combination with dexamethasone PO QD on days 1, 8 and 15. Treatment for cycle 1 continues for 21 days in the absence of disease progression or unacceptable toxicity. Patients then receive lenalidomide PO QD on days 1-21 alone or in combination with dexamethasone PO QD on days 1, 8, 15, and 22, or in combination with another drug. Treatment repeats every 28 days for up to 5 cycles in the absence of disease progression or unacceptable toxicity.

COHORT B: Patients with newly diagnosed multiple myeloma receive treatment as in Cohort A.

COHORT C: Patients with relapsed or refractory multiple myeloma receive lenalidomide PO QD on days 1-14 in combination with dexamethasone PO QD on days 1, 8 and 15 OR pomalidomide PO QD on days 1-21 in combination with dexamethasone PO QD on days 1, 8 and 15. Treatment for cycle 1 continues for 21 days in the absence of disease progression or unacceptable toxicity. Patients then receive lenalidomide PO QD on days 1-21 in combination with dexamethasone PO QD on days 1, 8, 15, and 22 OR pomalidomide PO QD on days 1-21 in combination with dexamethasone PO QD on days 1, 8, 15, and 22. Treatment repeats every 28 days for up to 5 cycles in the absence of disease progression or unacceptable toxicity.

COHORT D: Patients with relapsed multiple myeloma after lenalidomide maintenance receive treatment as in Cohort C.

After completion of study treatment, patients are followed up within 7 days.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Response Rates (RR) at First Assessment

    RR is defined as a binary variable. A success will be defined as patient who achieve a response of a partial response (PR) or better using the International Myeloma Working Group (IMWG) criteria. Biomarkers of interest will be identified and categorized into clinically relevant groups (e.g. positive vs. negative) by evaluating baseline and post treatment (after cycle one) biospecimens. RR will be estimated within each biomarker. Each cohort (A-D) will be evaluated separately and independently.

    Measured: 21 days

Secondary outcomes (2)
  1. Response Rates (RR) Among African American (AA) and White Patients

    Pearson's Chi-square (or Fischer Exact) test and 95% confidence intervals will be estimated to compare patients of different races descriptively.

    Measured: Up to completion of 1 cycle of treatment (21 days)

  2. Depth of Hematological Responses

    Correlation between the depth of hematological responses and biomarkers will be estimated. Logistic regressions and chi square (or Fischer exact) testing will be utilized.

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Bone Marrow Biopsy, Dexamethasone and Lenalidomide in people with Multiple Myeloma and Recurrent Multiple Myeloma, run by Mayo Clinic at 4 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 21 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 28 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 20 Aug 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Response Rates (RR) at First Assessment (time frame: 21 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Sep 2026.
