Trial Summary

What is the purpose of this trial?

Since CAR-T cell treatment of refractory myeloma has shown success, based on preclinical data, we posit that CAR-T cells expressing B-cell activating factor (BAFF) can become another strategy to treat refractory myeloma, even after relapse following BCMA targeting CAR-T cell treatment. This will be phase 1 study of BAFF ligand CAR-T cells in relapsed and refractory myeloma.

Will I have to stop taking my current medications?

The trial information does not specify if you need to stop taking your current medications. However, it mentions that more than 28 days must have passed since any prior treatment with investigational agents before lymphocyte collection, which might imply a need to pause certain treatments. It's best to discuss your specific medications with the trial coordinators.

What data supports the effectiveness of the treatment Autologous CAR-T cell therapy expressing the BAFF-ligand for multiple myeloma?

Research shows that BAFF ligand-based CAR-T cells can effectively target and kill multiple B cell cancers, including multiple myeloma, by binding to specific receptors on cancer cells. This suggests potential effectiveness for treating multiple myeloma.12345

What safety data exists for CAR-T cell therapy in humans?

CAR-T cell therapy has shown manageable safety concerns, including cytokine-release syndrome (a condition where the immune system releases too many proteins into the blood too quickly), different types of cytopenia (low blood cell counts), infections, and neurotoxicity (nerve damage). Efforts are being made to improve safety, such as incorporating a suicide gene safety system to control the therapy if needed.34678

How is the BAFF-ligand CAR-T cell treatment different from other treatments for multiple myeloma?

This treatment is unique because it uses a special type of immune cell called CAR-T cells that are engineered to target three specific receptors (BAFF-R, BCMA, and TACI) on cancer cells, which helps prevent the cancer from escaping treatment. This approach is different from other treatments that typically target only one receptor.12569

Treatment Details

Interventions

  • Autologous CAR-T cell therapy expressing the BAFF-ligand
Trial Overview The study tests a new CAR-T cell therapy using BAFF-ligand on patients whose myeloma has relapsed or is refractory to treatment. It's an early-phase trial to see how well these modified immune cells work against cancer that didn’t respond to previous therapies like BCMA targeting CAR-T cells.

Findings from Research

CAR T cell therapy, originally successful for treating leukemia, is now being explored for multiple myeloma, targeting specific antigens like BCMA and CD138.
Preliminary results from clinical trials indicate that CAR T cell therapy shows promise in treating multiple myeloma, although only a limited number of patients have been treated so far.
CARs in the Lead Against Multiple Myeloma.Ormhøj, M., Bedoya, F., Frigault, MJ., et al.[2018]
BAFF CAR-T cells, developed using a non-viral gene delivery method, effectively target and kill various B cell cancers, including mantle cell lymphoma, multiple myeloma, and acute lymphoblastic leukemia, both in laboratory settings and in animal models.
These CAR-T cells bind to three different BAFF receptors, which helps reduce the risk of cancer cells escaping treatment by losing the targeted antigen.

In a phase 1 study of 33 patients with relapsed or refractory multiple myeloma, the CAR T-cell therapy bb2121 demonstrated a high objective response rate of 85%, with 45% of patients achieving complete responses.
While bb2121 showed promising antitumor activity, it also had significant safety concerns, with 76% of patients experiencing cytokine release syndrome and 42% experiencing neurological toxic effects, highlighting the need for careful monitoring during treatment.
