What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new drug combination to determine the best dose and understand side effects for people with multiple myeloma, a type of blood cancer that has returned or isn't responding to treatment. The study combines three drugs—selinexor (a new potential drug), carfilzomib, and dexamethasone—to assess whether they work better together to stop cancer cell growth. The trial seeks participants diagnosed with multiple myeloma who have experienced a return or worsening of the disease and have tried at least two other treatments. As a Phase 1 trial, this research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive this new drug combination.

Will I have to stop taking my current medications?

The trial protocol does not specify if you need to stop taking your current medications. However, you cannot have had radiation, chemotherapy, or immunotherapy within 2 weeks before starting the trial, and you cannot be on other anticancer therapies during the trial.

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

Research has shown that the combination of selinexor, carfilzomib, and dexamethasone is generally well-tolerated by patients with multiple myeloma. One study found this treatment mix effective and manageable, even for those who have tried other treatments. Another study demonstrated that this combination helped control the disease in patients who didn't respond to carfilzomib alone. Although still in early testing, these findings suggest it might be a safe option for those considering joining a trial. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about the combination of Selinexor, Carfilzomib, and Dexamethasone for multiple myeloma because it introduces a unique mechanism of action. Unlike standard treatments that often target cell surface proteins or the bone marrow environment, Selinexor works by inhibiting the nuclear export protein XPO1, which can reactivate tumor suppressor proteins and lead to cancer cell death. This novel approach has the potential to enhance treatment efficacy and overcome resistance seen with current therapies. Additionally, combining Selinexor with Carfilzomib, a proteasome inhibitor, may further disrupt cancer cell survival, offering hope for improved outcomes for patients.

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

Research has shown that the combination of selinexor, carfilzomib, and dexamethasone, which participants in this trial will receive, effectively treats multiple myeloma, particularly in patients unresponsive to previous treatments. Studies have found that this combination can help patients regain responsiveness to treatments they had previously stopped responding to. It works well and is generally manageable for patients, with relatively few side effects. Early results suggest that even patients with extensive prior treatments still respond well to this drug mix. Overall, selinexor-based treatments appear promising for those whose disease hasn't improved with other therapies. ^{1 3 5 6 7}

Published Research Related to This Trial

Leflunomide, particularly its active metabolite A77 1726, has shown high tolerability and efficacy in treating advanced rheumatoid arthritis, with effective daily dosages of 10 mg and 25 mg, although the higher dose is linked to more side effects.

The drug works by inhibiting T- and B-cell proliferation and affecting cytokine signaling, with ongoing phase III trials aimed at confirming its effectiveness and safety in larger populations.

In a study of 75 patients with relapsed or refractory multiple myeloma, the combination of carfilzomib and dexamethasone (Kd56) showed a 60% overall response rate and a median progression-free survival (PFS) of 10 months, indicating its efficacy in a real-world clinical setting.

The treatment was well tolerated, with a low rate of adverse events, including no cases of neuropathy and only 10% of patients experiencing cardiovascular events above grade 3, suggesting a favorable safety profile for elderly and heavily pretreated patients.

In a study involving 122 patients with triple-class refractory myeloma, the combination of selinexor and dexamethasone resulted in a partial response or better in 26% of patients, demonstrating its potential efficacy as a treatment option for those who have not responded to existing therapies.

While selinexor was associated with common side effects like fatigue and nausea, it also led to significant thrombocytopenia in 73% of patients, highlighting the need for careful monitoring of blood cell counts during treatment.

Selinexor, when used in combination with dexamethasone or bortezomib and dexamethasone, showed an overall response rate of 29.5% in 44 patients with relapsed or refractory myeloma, indicating its efficacy as a treatment option.

The most common side effects included fatigue and thrombocytopenia, with 56% of patients requiring dose reductions; however, these adjustments did not negatively impact progression-free survival, suggesting that selinexor can be managed safely in clinical practice.

In a study of 1671 rheumatoid arthritis patients, the combination of methotrexate (MTX) and leflunomide (LEF) showed a comparable safety profile to MTX or LEF alone, with no increased risk of serious adverse events (SAEs).

The MTX + LEF combination had a significantly lower risk of SAEs and serious infections compared to biologic DMARDs and Janus kinase inhibitors, suggesting it may be a safer alternative for patients starting treatment.

In a study of 18 stable renal transplant patients, the combination of mycophenolate mofetil (MMF) and tacrolimus resulted in significantly higher levels of mycophenolic acid (MPA) compared to those receiving MMF with cyclosporine, indicating enhanced bioavailability and potential efficacy of MMF when used with tacrolimus.

The combination of tacrolimus and MMF showed a greater immunosuppressive effect in vitro, suggesting that this drug pairing may provide a more effective immunosuppressive strategy for renal transplant patients than previously understood.

In a phase I trial involving 21 patients with relapsed/refractory multiple myeloma, the combination of selinexor, carfilzomib, and dexamethasone was found to be tolerable, with a recommended phase II dose established at selinexor 60 mg, carfilzomib 20/27 mg/m2, and dexamethasone 20 mg.

The treatment resulted in significant response rates, with 71% of patients achieving at least a minimal response and a median overall survival of 22.4 months, demonstrating its efficacy even in patients who were refractory to carfilzomib.

In a study comparing lenalidomide-dexamethasone (len/dex) and melphalan-prednisone-lenalidomide (MPR) in 89 elderly patients with myeloma, both treatments showed similar efficacy in terms of time to progression, progression-free survival, and overall survival, indicating that either regimen can be effective for this patient group.

However, MPR was associated with significantly higher rates of severe hematologic toxicities, such as neutropenia and thrombocytopenia, suggesting that while both treatments are effective, len/dex may be a safer option with fewer severe side effects.

Selinexor, a selective inhibitor of nuclear export (SINE) compound, has shown promising efficacy in treating multiple myeloma (MM), particularly in patients with 'penta-refractory' MM, which is resistant to the five most effective current treatments.

Early phase clinical trials have established a safety profile for selinexor, especially when used in combination with low-dose dexamethasone, indicating it could be a valuable addition to existing treatment strategies for MM.

In the phase 3 BOSTON trial, the combination of selinexor, bortezomib, and dexamethasone significantly improved progression-free survival in adults with previously treated multiple myeloma compared to the standard bortezomib-dexamethasone regimen.

This triplet therapy demonstrated a manageable safety profile, with a lower incidence of peripheral neuropathy compared to the standard treatment, making it a promising option for patients.
