What is the purpose of this trial?

This trial tests a new treatment combination for multiple myeloma, a type of blood cancer, in patients whose cancer has returned or stopped responding to previous treatments. The researchers aim to determine if combining venetoclax (a targeted therapy) with isatuximab and dexamethasone benefits patients with a specific genetic marker (t(11;14)) linked to their condition. This trial is open to those with multiple myeloma with measurable disease who have tried at least three other treatments. As a Phase 2 trial, the research focuses on assessing the treatment's effectiveness in an initial, smaller group of people.

Will I have to stop taking my current medications?

The trial protocol does not specify if you must stop taking your current medications, but it does exclude certain treatments like chemotherapy, corticosteroids, and some other therapies within a few weeks before starting the study drugs. It's best to discuss your current medications with the study team to see if any adjustments are needed.

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

A previous study showed that combining venetoclax with other treatments yielded promising results and manageable side effects for patients with relapsed or refractory multiple myeloma. While some side effects occurred, most patients tolerated them well. Research has also shown that isatuximab, another drug in the combination, has a predictable safety profile. Compared to other treatments, its side effects were within the expected range. These findings suggest that the combination of venetoclax, isatuximab, and dexamethasone is reasonably safe, with side effects that most patients can manage. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Unlike the standard treatments for multiple myeloma, which usually include options like proteasome inhibitors, immunomodulatory drugs, and monoclonal antibodies, the combination of venetoclax, isatuximab, and dexamethasone brings something new to the table. Researchers are excited about this approach because venetoclax specifically targets the BCL-2 protein, which plays a key role in cancer cell survival, offering a novel mechanism of action. This treatment is particularly promising for patients with the t(11;14) genetic marker, a subgroup that might not respond as well to conventional therapies. By combining venetoclax with isatuximab, which targets CD38 on myeloma cells, and dexamethasone, a steroid that can enhance the effects of these drugs, this regimen could provide a more effective attack on the cancer cells.

What evidence suggests that this treatment might be an effective treatment for multiple myeloma?

Studies have shown that venetoclax, a type of medication, effectively treats patients with relapsed or hard-to-treat multiple myeloma, especially those with the genetic marker t(11;14). In this trial, participants will receive venetoclax combined with two other drugs, isatuximab and dexamethasone. Research indicates that this combination may help when other treatments fail. Patients with the t(11;14) marker who have tried similar combinations responded well, suggesting this approach could benefit them. Initial findings suggest that even low doses of venetoclax can be particularly helpful for this condition. Overall, this combination shows promise in managing multiple myeloma that has returned or resisted other treatments. ^{1 2 5 6 7}

Interventions

• Venetoclax

Trial Overview

The study tests Venetoclax combined with Isatuximab and Dexamethasone in patients whose multiple myeloma has returned after treatment or didn't respond to previous treatments. It's a phase 2 trial, which means it focuses on effectiveness and side effects.

How Is the Trial Designed?

Group I: open-label Experimental Treatment 1 Intervention

This is a Phase 2, multicenter, open-label study evaluating the safety and efficacy of venetoclax in combination with isatuximab and dexamethasone among RRMM patients who show the t(11;14) marker and currently show PD and have received at least 3 prior lines of therapy for multiple myeloma. All subjects in Dose Level 0 will receive 1) venetoclax, PO, at 400 mg every day (QD) on Days 1-28 of a 28-day cycle, 2) dexamethasone 40 mg IV, once weekly on Days 1, 8, 15, and 22 of a 28-day cycle where day 8 and 22 doses may be administered PO; and 3) isatuximab 10mg/kg, IV, on Days 1, 8, 15, and 22 of the first 28-day cycle, and then Days 1 and 15 during subsequent 28-day cycles. The primary safety analysis will focus on determining the DLTs for the study regimen, and occurrence of AEs throughout the study.

Published Research Related to This Trial

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.

The combination therapies involving isatuximab were generally well tolerated, maintaining health-related quality of life and showing a manageable safety profile without new safety concerns.

Isatuximab: A Review of Its Use in Multiple Myeloma. Frampton, JE.[2022]

Venetoclax, when combined with carfilzomib and dexamethasone, showed rapid initial effectiveness in two patients with multiple myeloma harboring the t(11,14)(q13;q32) genetic alteration, but the responses were short-lived, indicating a need for ongoing monitoring and potential adjustments in treatment.

The emergence of the t(11;14)(q13;q32) alteration during the disease progression highlights the importance of regular cytogenetic testing in multiple myeloma, as it can influence treatment strategies and outcomes in this challenging disease.
