Samer Al Hadidi: Cytopenias and Infection Risk With BCMA-Directed Bispecific Antibodies
Samer Al Hadidi, Associate Professor at UT Southwestern Medical Center, shared a post on LinkedIn:
“The Overlooked Burden of Cytopenias With BCMA-Directed Bispecific Antibodies
Hematologic toxicity is underappreciated:
- 87% of pts: grade 3-4 lymphopenia
- 55% grade 3-4 neutropenia (65% with teclistamab)
- 74% required dose interruptions
- 54.5% needed G-CSF
This is likely one of the important causes of higher grade infections with those agents.
We need to think about preventive strategies given the high efficacy of those agents.”
