Trial Summary

What is the purpose of this trial?

The investigators want to find out whether or not giving patients who have relapsed or refractory multiple myeloma (MM) the experimental medication combination iberdomide, carfilzomib, daratumumab, and dexamethasone (Iber-KDd) may produce better results than the current (standard of care) treatments. This study will examine the tolerability and efficacy of this combination therapy for all participants and the ability of this combination therapy to shrink or prevent MM from returning.

Do I have to stop taking my current medications for the trial?

The trial requires a 2-week period without prior multiple myeloma treatments before starting the study medications. However, some medications like corticosteroids for non-myeloma conditions and bone-targeting agents are allowed. It's best to discuss your specific medications with the trial team.

What data supports the effectiveness of the drug combination Iberdomide, Daratumumab, Carfilzomib, and Dexamethasone for treating multiple myeloma?

Research shows that combining carfilzomib, daratumumab, and dexamethasone is effective for patients with relapsed or refractory multiple myeloma, offering substantial efficacy and manageable safety. Additionally, carfilzomib combined with other drugs has been shown to significantly prolong progression-free survival, which means patients live longer without the disease getting worse. ^{1 2 3 4 5}

What makes the drug combination of Iberdomide, Daratumumab, Carfilzomib, and Dexamethasone unique for treating multiple myeloma?

This drug combination is unique because it includes Iberdomide, a novel immunomodulatory drug, alongside established treatments like Daratumumab, Carfilzomib, and Dexamethasone, potentially offering a new approach for patients with multiple myeloma, especially those who have relapsed or are refractory to other treatments. ^{1 3 4 6 7}

Trial Overview The study tests a new combination therapy called Iber-KDd (iberdomide with carfilzomib, daratumumab & dexamethasone) against standard treatments for multiple myeloma to see if it's more effective and tolerable in shrinking the cancer or preventing its return.

Participant Groups

Group I: Iber-KDd Combination Therapy Experimental Treatment 7 Interventions

Participants will receive Iber-KDd combination therapy for approximately 8 months. In the absence of disease progression, participants will continue on to Iber monotherapy. Participants with disease progression will discontinue study therapy but will continue to be followed for up to three (3) years after conclusion of Iber-KDd combination therapy.

Group II: Iber Monotherapy Experimental Treatment 1 Intervention

After completion of Iber-KDd combination therapy, and In the absence of disease progression, participants will then receive up to twelve (12) 28-day cycles of Iberdomide (Iber) monotherapy. Participants will receive Iber monotherapy for up to 12 months or until disease progression. Participants will be followed for up to three (3) years after conclusion of Iber monotherapy. Total study participation is up to five (5) years.

Findings from Research

In the phase 3 CANDOR study involving 466 patients with relapsed or refractory multiple myeloma, the combination of carfilzomib, daratumumab, and dexamethasone (KdD) demonstrated a significantly longer median progression-free survival of 28.6 months compared to 15.2 months for carfilzomib and dexamethasone (Kd), indicating KdD's potential as a new standard-of-care treatment.

While KdD showed improved efficacy, it was associated with a higher incidence of grade 3 or worse treatment-emergent adverse events (87% in KdD vs. 76% in Kd), including thrombocytopenia and pneumonia, highlighting the need for careful monitoring of patients receiving this combination therapy.

Carfilzomib, when used in combination with lenalidomide and dexamethasone, significantly prolongs progression-free survival (PFS) by 8.7 months in patients with relapsed multiple myeloma, based on results from the phase III ASPIRE study involving a multinational patient population.

The combination therapy has a manageable safety profile, with low incidences of severe adverse events, suggesting it is a viable treatment option for patients who have received prior therapies, although overall survival data is still pending.

In a study involving 929 patients with relapsed or refractory multiple myeloma, carfilzomib combined with dexamethasone significantly improved median progression-free survival (18.7 months) compared to bortezomib with dexamethasone (9.4 months), indicating greater efficacy of carfilzomib.

While both treatments had serious adverse events, carfilzomib was associated with a higher rate of serious adverse events (48%) compared to bortezomib (36%), suggesting that while carfilzomib may be more effective, it also carries a higher risk of serious side effects.

In a phase 3 study involving 466 patients with relapsed or refractory multiple myeloma, the combination of carfilzomib, dexamethasone, and daratumumab (KdD) significantly improved progression-free survival compared to carfilzomib and dexamethasone alone (Kd), with a hazard ratio of 0.63, indicating a 37% reduction in the risk of disease progression.

Despite a higher incidence of grade 3 or higher adverse events in the KdD group (82%) compared to the Kd group (74%), the overall safety profile was considered favorable, with similar rates of treatment discontinuation due to adverse events in both groups.

In a study involving 792 patients with relapsed multiple myeloma, the combination of carfilzomib with lenalidomide and dexamethasone significantly improved progression-free survival, with a median of 26.3 months compared to 17.6 months for the control group.

The carfilzomib group also showed a higher overall response rate (87.1% vs. 66.7%) and better health-related quality of life, indicating a favorable risk-benefit profile despite similar rates of serious adverse events between the two groups.

The combination therapy of daratumumab, carfilzomib, lenalidomide, and dexamethasone (D-KRd) was well tolerated in a study of 22 patients with newly diagnosed multiple myeloma, with a high overall response rate of 95%.

Most treatment-emergent adverse events were mild, with the most common being diarrhea and lymphopenia, and infusion-related reactions were primarily mild, indicating a favorable safety profile for D-KRd therapy.

In a phase 3 study (CASTOR) with a median follow-up of 19.4 months, the combination of daratumumab, bortezomib, and dexamethasone significantly improved progression-free survival (16.7 months) compared to bortezomib and dexamethasone alone (7.1 months), indicating its efficacy in treating relapsed/refractory multiple myeloma.

Daratumumab plus bortezomib and dexamethasone also showed a higher overall response rate (83.8% vs. 63.2%) and was particularly beneficial for patients with one prior line of therapy, demonstrating a favorable safety profile consistent over time.
