What is the purpose of this trial?

This trial tests a combination of four treatments—Bortezomib, Cyclophosphamide, Dexamethasone, and Isatuximab (also known as Sarclisa)—for individuals with multiple myeloma, a type of blood cancer. The main goal is to evaluate the efficacy and safety of these drugs, particularly in patients with kidney issues. Suitable participants have multiple myeloma with kidney problems and qualify for stem cell transplants. As a Phase 2 trial, this research measures the treatment's effectiveness in an initial, smaller group, offering participants a chance to contribute to significant advancements in multiple myeloma care.

Will I have to stop taking my current medications?

The trial protocol does not specify whether you need to stop taking your current medications. However, it does mention that no prior multiple myeloma-directed therapy is allowed except for specific medications like dexamethasone, bortezomib, and cyclophosphamide under certain conditions. It's best to discuss your current medications with the study team to get a clear answer.

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

Research has shown that the combination of Bortezomib, Cyclophosphamide, Dexamethasone, and Isatuximab is well-tolerated. One study found that this combination effectively treated multiple myeloma, even in patients with kidney problems. The safety profile of this drug mix aligns with the expected effects of each drug when used alone, suggesting that the treatment is generally safe. However, as with any medical treatment, side effects may occur, so discussing these with a doctor is important. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments for multiple myeloma?

Researchers are excited about the quadruple therapy for multiple myeloma because it combines four powerful drugs—Bortezomib, Cyclophosphamide, Dexamethasone, and Isatuximab—to tackle the disease from multiple angles. Unlike standard treatments, which might use one or two drugs, this regimen introduces Isatuximab, a monoclonal antibody, offering a new way to target and neutralize cancer cells. This comprehensive approach is designed to be especially beneficial for patients with renal impairment, who often have limited treatment options. By leveraging the unique mechanisms of each drug, this combination has the potential to improve outcomes and provide hope for those with this challenging condition.

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

This trial examines the combination of Bortezomib, Cyclophosphamide, Dexamethasone, and Isatuximab for treating multiple myeloma, a type of blood cancer. Research indicates that this combination can shrink cancer or halt its growth in many patients. In one study, 93% of patients experienced at least a partial response, with tumors either shrinking or remaining stable. The treatment was generally well-tolerated, as most people managed the side effects. This combination is under study because it attacks the cancer in various ways, potentially increasing its effectiveness. Overall, early findings suggest this treatment could be a strong option for those with multiple myeloma. ^{1 3 4 6 7}

Published Research Related to This Trial

In a Phase 1b study involving 73 patients with newly diagnosed multiple myeloma who were ineligible for autologous stem cell transplantation, the combination of isatuximab with bortezomib-lenalidomide-dexamethasone (Isa-VRd) showed a remarkable overall response rate of 98.6%, with over half of the patients achieving a complete response.

While 79.5% of patients experienced grade ≥3 treatment-emergent adverse events, the pharmacokinetics of isatuximab remained consistent, indicating that the combination treatment does not affect its metabolism, supporting further investigation in larger trials.

In a phase 1b study involving 45 patients with relapsed/refractory multiple myeloma, the combination of isatuximab, pomalidomide, and dexamethasone showed a 62% overall response rate and a median duration of response of 18.7 months, indicating significant efficacy in a heavily pretreated population.

The safety profile was manageable, with common adverse events including fatigue and infections, and the recommended dose for future studies was determined to be 10 mg/kg of isatuximab given weekly for the first four weeks and then every two weeks.

In the phase 3 ICARIA-MM trial, isatuximab combined with pomalidomide-dexamethasone significantly improved median progression-free survival (mPFS) in high-risk multiple myeloma patients, showing 7.5 months compared to 3.7 months with standard treatment.

Despite a higher incidence of grade ≥3 adverse events in high-risk patients receiving isatuximab (95.7% vs. 67.6% in the control group), the treatment did not lead to increased discontinuation or treatment-related mortality, indicating a favorable safety profile.

The treatment landscape for multiple myeloma has expanded significantly with the approval of 10 new therapies over the past decade, highlighting the effectiveness of 3-drug combinations over 2-drug therapies, as supported by current guidelines.

Recent studies, including the approval of daratumumab combined with bortezomib, melphalan, and prednisone, suggest that 4-drug combinations may offer benefits for newly diagnosed patients who are not pursuing autologous transplant, with ongoing research exploring their efficacy in various patient settings.

In a subgroup analysis of the CASTOR trial involving 498 patients, daratumumab combined with bortezomib and dexamethasone (D-Vd) significantly prolonged progression-free survival (PFS) in patients with high cytogenetic risk (12.6 months) compared to bortezomib and dexamethasone alone (6.2 months).

D-Vd also demonstrated a higher rate of minimal residual disease (MRD) negativity, indicating deeper responses in treatment effectiveness, while maintaining a safety profile consistent with the overall study population.

In a study of 70 patients with relapsed or refractory multiple myeloma, a four-drug combination therapy (bortezomib, cyclophosphamide, thalidomide, and dexamethasone) achieved an impressive overall response rate of 88%, with 46% of patients experiencing a complete response.

The treatment demonstrated a median progression-free survival of 14.6 months and a median overall survival of 31.6 months, while showing manageable side effects, with serious adverse events occurring in a small percentage of patients.

Isatuximab, an anti-CD38 monoclonal antibody, significantly improves progression-free survival and tumor response when combined with pomalidomide and dexamethasone in patients with relapsed and refractory multiple myeloma, based on phase III studies.

In a phase 2 study involving 46 patients with newly diagnosed multiple myeloma, the quadruplet regimen of elotuzumab, carfilzomib, lenalidomide, and dexamethasone (Elo-KRd) achieved a stringent complete response (sCR) and/or measurable residual disease (MRD)-negativity rate of 58% after 8 cycles, indicating significant efficacy without the need for autologous stem cell transplant (ASCT).

The study demonstrated a 3-year progression-free survival (PFS) rate of 72% overall, and an impressive 92% for patients who achieved MRD-negativity, suggesting that MRD-guided therapy could allow for reduced treatment exposure while maintaining effective outcomes.

In a study of 24 patients with relapsed/refractory multiple myeloma (RRMM) showing only biochemical progression, the combination of isatuximab and dexamethasone with methylprednisolone resulted in a 63% overall response rate and a 79% clinical benefit rate, indicating its efficacy.

The treatment was well tolerated, with only 5 instances of Grade ≥3 adverse events, primarily lymphocytopenia, and no severe complications related to respiratory infections, anemia, or thrombocytopenia, suggesting a favorable safety profile.
