What You Need to Know Before You Apply

What is the purpose of this trial?

The purpose of this study is to test whether regulatory T-cell reduction is possible and safe in myeloma subjects undergoing autologous stem cell transplantation (ASCT).

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

The trial requires that you do not use systemic immunosuppressive medications, including corticosteroids and certain other drugs. If you are taking these, you would need to stop them to participate.

Is stem cell transplantation for multiple myeloma safe?

Stem cell transplantation for multiple myeloma has been generally well tolerated, but some patients experience side effects like cytokine release syndrome (a condition where the immune system releases too many proteins into the blood too quickly) and hematologic toxicities (blood-related side effects). While these treatments show promise, they can also have severe adverse events, so ongoing research is needed to better understand and manage these risks.12345

How does the treatment of Regulatory T-cell reduction differ from other treatments for multiple myeloma?

Regulatory T-cell reduction in multiple myeloma is unique because it focuses on decreasing the number of regulatory T cells, which are known to suppress the immune response against cancer cells. This approach aims to enhance the body's natural ability to fight the cancer, unlike traditional treatments that primarily target the cancer cells directly.56789

What data supports the effectiveness of the treatment for reducing regulatory T-cells in multiple myeloma patients?

Research suggests that higher levels of regulatory T-cells (a type of immune cell that can suppress the body's immune response) are linked to poorer outcomes in multiple myeloma patients. Reducing these cells might improve the effectiveness of treatments like donor lymphocyte infusions (DLIs) by enhancing the body's ability to fight the cancer.56789

Are You a Good Fit for This Trial?

This trial is for adults aged 21-70 with symptomatic multiple myeloma who are candidates for stem cell transplantation. They must have a life expectancy over 12 weeks, be HIV negative, not have active hepatitis B or C, and no major organ issues. Pregnant women, those on immunosuppressants or with autoimmune diseases cannot participate.

Published Research Related to This Trial

In a study involving 15 multiple myeloma patients undergoing autologous stem cell transplantation (ASCT), two methods of depleting regulatory T (Treg) cells were tested, showing that both in vivo (IVTRD) and ex vivo (EVTRD) methods significantly reduced Treg levels post-transplant.
The ex vivo method (EVTRD) effectively removed 90% of Treg cells from the stem cell grafts, and both methods delayed Treg recovery, which could enhance the effectiveness of post-transplant immunotherapies and improve patient outcomes.

CAR T cell therapies targeting BCMA have shown promising results in early clinical trials for treating multiple myeloma, indicating potential for long-lasting remissions.
However, these therapies are associated with significant toxicities, including cytokine release syndrome and neurotoxicity, highlighting the need for ongoing research to improve their safety and effectiveness.

Monoclonal antibodies like elotuzumab and daratumumab have advanced the treatment of multiple myeloma, while CAR T cell therapy is emerging as a promising option for patients with relapsed/refractory multiple myeloma, offering hope for those with limited treatment options.
Despite its potential efficacy, CAR T cell therapy can lead to severe adverse events and toxic deaths, highlighting the need for better understanding and management strategies for these toxicities in clinical practice.
