Talquetamab, a bispecific antibody, has shown potential neurological effects, but instances are infrequent, according to a nurse practitioner at UCSF.
The MonumenTAL-1 study reported neurotoxicity in 10% and 5% of patients receiving 405 mcg and 800 mcg doses of talquetamab, respectively, with most cases being low grade and resolving.
Immune effector cell-associated neurotoxicity syndrome occurred in 10.7% and 11% of patients receiving talquetamab at 0.4 mg/kg and 0.8 mg/kg, respectively, in the phase 2 portion of the trial.
Standard monitoring, including Immune Effector Cell Encephalopathy (ICE) scores every 12 hours, helps in closely observing and managing potential neurological effects in patients.
