tafasitamab · CD19
Check my plan vs. these
Immune & cytokine safety
B-cell depletion with reduced serum IgG and reduced TDAR (KLH primary, tetanus toxoid secondary response)
“The findings correlated with reduced IgG concentration in serum and a reduction in primary and secondary antibody response to keyhole limpet haemocyanin (KLH) and tetanus toxoid (TT) respectively, in an assessment of the T-cell dependent antibody response (TDAR).”
✓ VerifiedEMA assessment report, p. 37Source ↗
Biodistribution & persistence
TCR (human, monkey): binding to B-lineage mononuclear leukocytes, blood lymphocytes and marrow precursors; no off-target binding
“There was no off-target binding of tafasitamab detected in tissue panels from the human and cynomolgus monkey.”
✓ VerifiedFDA multi-discipline review, p. 34Source ↗
Modality-specific risk
B-cell depletion with immune dysfunction, including potential neonatal B-cell depletion after in utero exposure
“Based on the WOE risk assessment, treatment of pregnant women with tafasitamab may result in depletion of B cells and thus dysfunction of immune response in a newborn.”
✓ VerifiedFDA multi-discipline review, p. 35Source ↗
Anti-drug antibodies: animals
Monkey ADA in 8/10 (2 mg/kg), 3/10 (10 mg/kg), 3/10 (50 mg/kg); ADA-mediated clearance lowered exposure with B-cell recovery
“This response was greatest at 2 mg/kg (8 of 10 animals), less at 10 mg/kg (3 of 10 animals) and at 50 mg/kg (3 of 10 animals). There was a relationship between tafasitamab antibody-mediated clearance and decline in tafasitamab concentrations and concomitant recovery of B-cells, especially at the low dose.”
✓ VerifiedEMA assessment report, p. 34Source ↗
Anti-drug antibodies: patients
ADA in 2.5% (2/81) of DLBCL patients (L-MIND) and 0.9% (3/327) of FL patients (inMIND)
“Following MONJUVI treatment, anti-tafasitamab-cxix antibodies developed in 2.5% (2/81) of patients with DLBCL in Study L-MIND (up to 23 cycles) and 0.9% (3/327) of patients with FL in Study inMIND (up to 12 cycles)”
