Overview
epcoritamab
bispecific T cell engager
- immunosuppressive oncologic agent
- myelosuppressive oncologic agent
- caution advised w/ narrow therapeutic index drugs metabolized by CYP450 liver enzymes, esp. at initiation and up to 14 days after first 48 mg dose on Day 15 of Cycle 1 or during/after CRS; epcoritamab may transiently increase cytokine release leading to suppression of CYP450 metabolic function, causing incr. levels of concomitant drugs, risk of adverse effects

Safety/Monitoring .
Monitoring Parameters
pregnancy test at baseline; CBC; s/sx cytokine release syndrome, neurological toxicities x24h in hospital after first 48 mg injection and as clinically indicated
Pregnancy/Lactation .
Pregnancy
Clinical Summary
weigh risk/benefit during pregnancy; no human or animal data available; possible risk of fetal harm, incl. embryo-fetal death and B-cell lymphocytopenia, based on drug's mechanism of action
Individuals of Reproductive Potential
obtain pregnancy test before tx start; avoid pregnancy by using effective contraception during tx and x4mo after D/C in pts of childbearing potential
Lactation
Clinical Summary
avoid breastfeeding during tx and x4mo after D/C; no human data available to assess risk of infant harm or effects on milk production
Pharmacology .
Metabolism: catabolism; CYP450: unknown
Excretion: unknown; Half-life: 22 days
Subclass: Immunotherapy, Bispecific CD3 T-Cell Engagers ; Immunotherapy, CD20 Inhibitors
Mechanism of Action
binds to CD20 receptors on B-cells, and CD3 receptors on T-cells, leading to T-cell activation and subsequent lysis of CD20-positive B-cells (bispecific T-cell engager)
