Management of toxicities of immunotherapy.BiTE = bispecific T-cell engager; CAR = chimeric antigen receptor; CRS = cytokine release syndrome; HLH = haemophagocytic lymphohistiocytosis; ICANS = immune effector-cell associated neurotoxicity syndrome; ICI = immune checkpoint inhibitor; irAE = immune-related adverse events

Grades 2 and 3 of the selected immune-related adverse events (irAEs)

irAE Grade 2 Grade 3
Maculo-papular rash Papules and/or pustules covering 10−30% BSA, which may or may not be associated with symptoms of pruritus or tenderness; associated with psychosocial impact; limiting instrumental ADL; papules and/or pustules covering > 30% BSA with or without mild symptoms Papules and/or pustules covering > 30% BSA with moderate or severe symptoms; limiting self-care ADL; associated with local superinfection with oral antibiotics indicated
Diarrhoea/enterocolitis Increase of 4−6 stools/day over baseline Increase of ≥ 7 stools/day over baseline
ILD/Pneumonitis Symptomatic (presence of new or worsening symptoms: dyspnoea, cough), medical intervention indicated, limiting instrumental ADL Severe symptoms, oxygen indicated, limiting self-care ADL
Rheumatologic toxicity Moderate pain, stiffness and/or weakness limiting instrumental ADL Severe pain, stiffness and/or weakness limiting self-care ADL
Neuro-muscular toxicity Moderate pain associated with weakness, limiting instrumental ADL Pain associated with severe weakness, limiting self-care ADL
Hepatotoxicity ALT or AST 3−5 × ULN ALT > 5 × or AST < 20 × ULN
Renal toxicity Serum creatinine >1.5−3 × above the baseline or the UNL, KDIGO stage 2: increase in serum creatinine 2−2.9 × above the baseline Serum creatinine > 3 × above the baseline or > 3−6 × ULN, KDIGO stage 3: increase in serum creatinine > 3 × or to > 4.0 mg/dl or initiation of dialysis

Grades of the cytokine release syndrome (CRS) and the immune cell-associated neurologic syndrome ICANS

Toxicity Grade 1 Grade 2 Grade 3 Grade 4
CRS Fever: ≥ 38°C Hypotension: none Hypoxia: none Fever: ≥ 38°C AND Hypotension: not requiring vasopressor AND/OR Hypoxia Fever: ≥ 38°C AND Hypotension: requiring vasopressor AND/OR Hypoxia Fever: ≥ 38°C AND Hypotension requiring multiple vasopressors AND/OR Hypoxia requiring positive pressure
ICANS ICE score: 7−9 No depressed level of consciousness ICE score: 3−6 AND/OR Mild somnolence awaking to voice ICE score: 0−2 AND/OR Depressed level of consciousness awakening only to tactile stimulus AND/OR clinical seizure focal or generalized that resolve with intervention AND/OR Focal or local oedema on neuroimaging ICE sore: 0 AND/OR Stupor or coma AND/OR Life-threatening prolonged seizure AND/OR Diffuse cerebral oedema on neuroimaging, decerebrate or decorticate posturing or papilledema, cranial nerve VI palsy, or Cushing’s triad
