Lass than 5% discontinued treatment due to AEs[1]

Cytokine release syndrome (CRS)

Most CRS events experienced were low grade (grades 1 and 2) – less than one percent (0.6%) of events were grade 3, affecting only one patient, and no grade 4 or fatal events occurred[1][2]

The step-up dosing schedule, including required pretreatment medicines,* was used to mitigate the risk of severe CRS.[2]

Median time to CRS onset was 2 days (range: 1–6 days) after the most recent dose, and all were resolved with a median duration of 2 days (range: 1–9).[1][2]

Nearly all CRS events occurred during the step-up dosing schedule – less than 3% of patients developed their first event during subsequent doses.[1][2]

Treatment with supportive care, tocilizumab and/or corticosteroids should be instituted based on severity of CRS.[2]

*Pretreatment doses include corticosteroid (oral or intravenous dexamethasone 16 mg), antihistamine (oral or intravenous diphenhydramine 50 mg or equivalent) and antipyretic (oral or intravenous paracetamol 650 mg to 1,000 mg or equivalent)[2]

Neurological toxicities

Neurological toxicities were mostly low grade and manageable*[1]

Most neurological toxicities were grade 1 and grade 2 (experienced by 8.5% and 5.5% of all patients, respectively).[3]

ICANS occurred in a small number of patients (3.0%; all grade 1 or 2) and most commonly manifested as confused state (1.2%) and dysgraphia (1.2%).[2]

Treatment-related headache was the most frequently reported neurotoxic event (8.0%), followed by ICANS (3.0%).[2][3]

* Median follow up of 14.1 months

AE, adverse event; CRS, cytokine release syndrome; ICANS, immune effector cell-associated neurotoxicity syndrome; MM, multiple myeloma; MoA, mechanism of action; R/R, relapsed and refractory; VGPR, very good partial response
