Bispecific Antibodies Teclistamab and Talquetamab Show Promise in Multiple Myeloma Treatment
- Teclistamab and talquetamab, bispecific antibodies, demonstrate efficacy in relapsed/refractory multiple myeloma by reducing soluble BCMA levels in responding patients.
- A reduction in sBCMA levels correlates with the depth of treatment response, with complete or stringent complete responses showing nearly 100% sBCMA reduction.
- Baseline sBCMA levels correlate with tumor burden, suggesting sBCMA as a potential marker, and do not significantly affect teclistamab exposure, indicating maintained clinical activity.
- Clinical trials are underway to evaluate bispecific antibodies in earlier lines of therapy and maintenance settings, potentially transforming myeloma treatment.
