- Adult, Older adult
Who may be able to join
- Confirmed diagnosis of symptomatic multiple myeloma (MM).
- Eastern Cooperative Oncology Group performance status (ECOG) score of 0, 1, or 2.
- Received 3 to 6 cycles of an induction therapy that includes a proteasome inhibitor (PI) and immunomodulatory (IMiD) [eg, bortezomib thalidomide and dexamethasone (VTd), lenalidomide, bortezomib and dexamethasone (RVd)] with or without a CD38 monoclonal antibody, daratumumab + bortezomib/thalidomide/dexamethasone [D-VTd] and daratumumab + bortezomib/ lenalidomide/dexamethasone [D-VRd]), or VCd / daratumumab + bortezomib/cyclophosphamide/dexamethasone [D-VCd], and followed by a single or tandem autologous stem cell transplantation (ASCT). Post-stem cell transplant consolidation is permitted.
- Participants within 12 months (single transplant) or 15 months (tandem transplant) from initiation of induction therapy who achieved at least a partial response (PR) after autologous stem cell transplantation (ASCT) with or without consolidation, according to International Myeloma Working Group (IMWG 2016) criteria.
Who cannot join
- Progressive disease or clinical relapse (as defined by IMWG response criteria) following ASCT with or without consolidation or is not responsive to primary therapy.
- Smoldering myeloma, solitary plasmacytoma or nonsecretory myeloma.
- Known central nervous system/meningeal involvement of MM.
- Prior history of malignancies, other than MM, unless the participant has been free of the disease for ≥ 5 years.
- Other protocol-defined Inclusion/Exclusion criteria apply.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The purpose of this study is to compare the effectiveness of iberdomide maintenance to lenalidomide maintenance therapy after autologous stem cell transplantation (ASCT) in participants with newly diagnosed multiple myeloma (NDMM).

Key inclusion criteria (4 listed)
- Confirmed diagnosis of symptomatic multiple myeloma (MM).
- Eastern Cooperative Oncology Group performance status (ECOG) score of 0, 1, or 2.
- Received 3 to 6 cycles of an induction therapy that includes a proteasome inhibitor (PI) and immunomodulatory (IMiD) [eg, bortezomib thalidomide and dexamethasone (VTd), lenalidomide, bortezomib and dexamethasone (RVd)] with or without a CD38 monoclonal antibody, daratumumab + bortezomib/thalidomide/dexamethasone [D-VTd] and daratumumab + bortezomib/ lenalidomide/dexamethasone [D-VRd]), or VCd / daratumumab + bortezomib/cyclophosphamide/dexamethasone [D-VCd], and followed by a single or tandem autologous stem cell transplantation (ASCT). Post-stem cell transplant consolidation is permitted.
- Participants within 12 months (single transplant) or 15 months (tandem transplant) from initiation of induction therapy who achieved at least a partial response (PR) after autologous stem cell transplantation (ASCT) with or without consolidation, according to International Myeloma Working Group (IMWG 2016) criteria.
Key exclusion criteria (5 listed)
- Progressive disease or clinical relapse (as defined by IMWG response criteria) following ASCT with or without consolidation or is not responsive to primary therapy.
- Smoldering myeloma, solitary plasmacytoma or nonsecretory myeloma.
- Known central nervous system/meningeal involvement of MM.
- Prior history of malignancies, other than MM, unless the participant has been free of the disease for ≥ 5 years.

Eligibility is decided by the study team after screening; this overview does not establish that a patient qualifies. Full inclusion and exclusion criteria.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Iberdomide and Lenalidomide in people with Multiple Myeloma, run by Bristol-Myers Squibb at 269 sites in 34 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 4 inclusion and 5 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: under way, not looking for participants, as of the sponsor's last update on 17 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 269 sites in United States, China, Japan, Germany, Italy and 29 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
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?
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?
Progression-free survival (PFS) (time frame: Up to 6 years). 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 17 Sep 2026.
