Iberdomide and Daratumumab As Maintenance Therapy After an Autologous Stem Cell Transplant for Multiple Myeloma
(IBEX)
What this study is about
The goal of this phase 2 clinical trial is to learn if patients with Multiple Myeloma who are minimal residual disease positive after initial therapy (including an autologous stem cell transplant \[ASCT\]) will benefit from maintenance therapy with Iberdomide and injected under the skin (SC) Daratumumab.

Interventions
DRUG
Iberdomide
Iberdomide 1.0mg daily for days 1-21 of a 28-day cycle, an increase to 1.3 mg daily on Day 1-21 of a 28-day cycle is allowed at cycle 4 or higher if the 1.0 mg dose was well tolerated.
DRUG
Daratumumab/rHuPH20 Co-formulation
Daratumumab/rHuPH20 will be dosed as follows: * Daratumumab/rHuPH20 1800 mg SC days 1, 8, 15, 22 (28-day cycle; cycles 1-2) * Daratumumab/rHuPH20 1800 mg SC days 1, 15 (28-day cycle; cycles 3-6) * Daratumumab/rHuPH20 1800 mg SC day 1 (28-day cycle; cycles 7-26)
Primary outcome measures
Rate of MRD (-) at 12 months
Time frame: 12 months
Summarized by a binomial response rate and its associated 2-sided 90% confidence interval (CI) using Pearson-Klopper method.

Inclusion criteria
- Multiple Myeloma patients who have received prior DARA-containing induction therapy and have attained at least a partial response. 2. Patients who have completed Autologous Stem Cell Transplant (ASCT) 90-150 days prior to registration, without any post-ASCT therapy and without post-ASCT disease progression (according to IMWG criteria) 3. Patients who are Minimal Residual Disease positive (MRD (+)) as measured by the ClonoSEQ assay using a sensitivity of 10-5, measured 90-150 days following ASCT. 4. Prior DARA-containing induction therapy (at least 3 cycles), attaining at least a partial response. 5. Completed ASCT within 90-150 days prior to registration, without any post-ASCT therapy and without evidence of post-ASCT disease progression (according to IMWG criteria) 6. MRD (+) at the time of study enrollment using the clonoSEQ NGS (next-generation sequencing) assay. Patients with an M-spike of ≥ 0.5 g/dL and/or an abnormal free light chain ratio (with an involve

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
