About this study

Official title: Phase 1/2 Study of Etentamig in Combination With a CELMoD Agent for the Treatment of Patients With Relapsed/Refractory Multiple Myeloma

Multiple myeloma (MM) is a plasma cell disease characterized by the growth of clonal plasma cells in the bone marrow. The purpose of this study is to assess the adverse events and change in disease activity of etentamig in combination with a cereblon E3 ligase modulatory drug (CELMoD) agent in adult participants with relapsed/refractory (R/R) multiple myeloma (MM). Adverse events and change in disease state will be assessed.

Etentamig is an investigational drug being developed for the treatment of R/R MM. Study doctors put the participants in groups called treatment arms. Multiple doses of etentamig in combination with iberdomide will be explored. Each treatment arm receives a different dose of etentamig and iberdomide to determine a tolerable dose. Approximately 135 adult participants with R/R MM will be enrolled in the study in approximately 50 sites worldwide.

Read more

In phase 1 participants will receive escalating intravenous (IV) etentamig in combination with oral iberdomide. In phase 2 participants will receive IV etentamig at one of two doses in combination with oral iberdomide, as part of the approximately 129 month study duration.

There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at an approved institution (hospital or clinic). The effect of the treatment will be frequently checked by medical assessments, blood tests, questionnaires and and monitoring of side effects.

B-cell maturation antigen (BCMA) chimeric antigen receptor T-cell (CAR-T) or BCMA antibody-drug conjugate (ADC) are allowed.

What is being measured

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

  1. Phase 1: Dose-Limiting Toxicities (DLT)s of Etentamig when given in Combination with Iberdomide in Participants with Relapsed/Refractory Multiple Myeloma (RRMM)

    DLT events are defined as clinically significant adverse events or abnormal laboratory values assessed as unrelated to disease progression, underlying disease, intercurrent illness, or concomitant medications.

    Measured: Up to Approximately 56 Days

  2. Number of Participants with Adverse Events (AE)s

    An adverse event is defined as any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment.

    Measured: Up to Approximately 129 Months

Secondary outcomes (9)

  1. Partial Response (PR) Response Rate (RR)

    PR is defined >= 50% reduction of serum M-protein and reduction in 24-hour urinary M-protein by >= 90% or to < 200 mg per 24 hours, if the serum and urine M-protein are unmeasurable, a >= 50% decrease in the difference between involved and uninvolved FLC levels is required in place of the M-protein criteria, if the serum and urine M-protein are unmeasurable, and serum free light assay is also unmeasurable, a >= 50% reduction in plasma cells is required in place of M-protein, provided baseline bone marrow plasma cell percentage was >= 30%, >= 50% reduction in the size of soft tissue plasmacytomas is also required, if present at baseline.

    Measured: Up to 3 Years

  2. Very Good Partial Response (VGPR) RR

    VGPR is defined as serum and urine M-protein detectable by immunofixation but not on electrophoresis or >= 90% reduction in serum M-protein plus urine M-protein < 100 mg per 24 hours, for participants in whom the only measurable disease is by serum free light chains (FLC) levels, VGPR is defined as >= 90% decrease in the difference between involved and uninvolved FLC levels.

    Measured: Up to 3 Years

  3. Complete Response (CR) RR

    CR is defined negative immunofixation on the serum and urine (regardless of whether disease at baseline was measurable on serum, urine, both, or neither), disappearance of any soft tissue plasmacytomas, < 5% plasma cells in bone marrow, and for participants in whom the only measurable disease is by serum FLC levels, a normal FLC ratio is also required.

    Measured: Up to 3 Years

  4. Stringent Complete Response (sCR) RR

    sCR is defined negative immunofixation on the serum and urine (regardless of whether disease at baseline was measurable on serum, urine, both, or neither), disappearance of any soft tissue plasmacytomas, < 5% plasma cells in bone marrow, normal FLC ratio and absence of clonal cells in bone marrow by immunohistochemistry (kappa/lambda ratio <= 4:1 or >= 1:2 for kappa and lambda participants, respectively, after counting >= 100 plasma cells).

    Measured: Up to 3 Years

  5. Overall Response Rate (ORR)

    ORR (PR + VGPR + CR + sCR) will be defined as the proportion of participants who achieved a PR or better.

    Measured: Up to 3 Years

  6. Progression-Free Survival (PFS)

    PFS is defined as the number of days from the date of first dose to the date of earliest disease progression or death.

    Measured: Up to 3 Years

  7. Duration of Response (DOR)

    DOR is defined as the number of days from the date of first response (sCR, CR, VGPR, or PR) to the earliest recurrence, progressive disease, or death, whatever occurs first.

    Measured: Up to 3 Years

  8. Time-to-Progression (TTP)

    TTP will be defined as the number of days from the date of first dose to the date of earliest disease progression.

    Measured: Up to 3 Years

  9. Minimal Residual Disease (MRD) negativity

    The MRD negativity rate is defined as the proportion of participants who achieve MRD negative status.

    Measured: Up to 3 Years

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Etentamig and Iberdomide in people with Multiple Myeloma, run by AbbVie at 27 sites in 7 countries.

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 3 inclusion and 3 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: looking for participants now, as of the sponsor's last update on 12 May 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 27 sites in United States, Australia, France, Japan, Canada and 2 more countries. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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

Contact ABBVIE CALL CENTER (844-663-3742, abbvieclinicaltrials@abbvie.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Phase 1: Dose-Limiting Toxicities (DLT)s of Etentamig when given in Combination with Iberdomide in Participants with Relapsed/Refractory Multiple Myeloma (RRMM) (time frame: Up to Approximately 56 Days). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06896916.

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 12 May 2026; AzTrials last refreshed its copy on 7 Nov 2026.
