Treating advanced cases in relapsed or refractory multiple myeloma remains a significant challenge
There remains a need for improved treatment options for patients with relapsed or refractory multiple myeloma, including those who have progressed following treatment with multiple classes of drugs.
As multiple myeloma progresses, relapses become more aggressive with each line of therapy, and remissions become progressively shorter.1-7
Triple class refractory disease occurs when patients relapse on or are refractory to one proteasome inhibitor, one immunomodulatory agent, and one anti-CD38 monoclonal antibody.8-11
Monoclonal Antibodies
The complex nature of relapsed or refractory multiple myeloma requires specific treatment solutions.
Patients with triple-class refractory disease tend to have more progressive disease, high-risk cytogenetic profiles, fewer treatment options, and poorer prognoses.8,11-13
BCMA is an exciting targeting option for the potential treatment of relapsed or refractory multiple myeloma
B-cell maturation antigen (BCMA) is a cell-surface protein predominantly expressed on terminally differentiated B cells, that regulates B-cell proliferation, survival, and maturation and differentiation into plasma cells.14-18
Multiple BCMA-targeted therapies are being studied across the industry
These treatments all work in different ways to target BCMA.19-24 T cell redirecting bispecific antibodies, for example, work by binding to BCMA molecules on the surface of multiple myeloma cells and CD3 molecules on the surface of the patient's T cells. Once bound to both cells, the T cell is in proximity to the multiple myeloma cell and can trigger myeloma cell death.25
IT IS IMPORTANT TO STAY INFORMED ABOUT NEW TARGETS AND THERAPEUTIC STRATEGIES UNDER INVESTIGATION.
Janssen Biotech, Inc., is committed to investigating T cell redirecting bispecific antibodies to help address the unmet need for patients with relapsed or refractory multiple myeloma26
Janssen Biotech, Inc., is also investigating GPRC5D, a transmembrane protein highly expressed on plasma cells with minimal expression in healthy tissues, as a multiple myeloma target.27
