What is the purpose of this trial?

This trial investigates a new combination of medications to help people with multiple myeloma, a type of blood cancer, when other treatments have stopped working. Researchers aim to determine if this combination can prevent the cancer from returning or growing. The trial will assess the effectiveness of these drugs together and their tolerability for patients. Individuals diagnosed with multiple myeloma, whose condition has worsened despite previous treatments, might be suitable for this trial. As a Phase 2 trial, this research focuses on measuring the treatment's effectiveness in an initial, smaller group of participants.

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.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Studies have shown that the combination of iberdomide, carfilzomib, daratumumab, and dexamethasone is generally well-tolerated in patients with multiple myeloma. Research indicates that this combination, often called Iber-KDd, was safe for patients who had already received many treatments. Its safety profile aligns with findings from earlier studies involving similar drugs.

Iberdomide, when used alone, has also demonstrated general safety. It showed promising results even in patients who had undergone many previous treatments. Overall, the available data suggest that these treatments are well-tolerated, with no major safety concerns reported so far. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about these treatments for multiple myeloma because they combine several innovative therapies that work together to tackle the disease more effectively. Unlike traditional treatments that might focus on a single pathway or mechanism, this combination uses Iberdomide, which modulates the immune system to enhance anti-cancer responses, alongside Carfilzomib and Daratumumab, which target and destroy cancer cells directly. Additionally, the use of Dexamethasone helps reduce inflammation and enhances the efficacy of the other drugs. This multi-faceted approach aims to improve treatment outcomes and provide a more comprehensive attack on multiple myeloma, offering hope for better patient responses compared to existing options.

What evidence suggests that this trial's treatments could be effective for multiple myeloma?

Studies have shown that using the drugs carfilzomib, daratumumab, and dexamethasone together effectively treats multiple myeloma, a type of blood cancer. In this trial, participants will receive a combination of these drugs with iberdomide, known as Iber-KDd therapy, which has shown promising results for patients who haven't had success with other treatments. Patients using similar drug combinations have experienced significant reductions in their cancer. Additionally, research on iberdomide alone has demonstrated that it can help patients live longer. These findings suggest that Iber-KDd therapy could be a strong option for managing multiple myeloma. ^{1 2 3 4 6}

• Daratumumab
• Dexamethasone
• Iberdomide

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.

How Is the Trial Designed?

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

Prior to Iber-KDd combination therapy, participants will receive Acetaminophen, Diphenhydramine and Montelukast therapy per protocol. Participants will receive up to eight (8) 28-day cycles of combination Iberdomide (I), Carfilzomib (K), Daratumumab (D), and Dexamethasone (d) (Iber-KDd) therapy. 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.

Published Research Related to This Trial

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 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.

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 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.

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 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.
