| Bioactivity | Nivolumab is a programmed death receptor-1 (PD-1) blocking human IgG4 antibody to treat advanced (metastatic) non-small cell lung cancer. |
| Invitro | Nivolumab binds to CHO cells expressing PD-1 with an EC50 of 1.66 nM, but does not bind to the parental CHO cell line. Nivolumab binds to PD-1 on activated T cells with an EC50 of 0.64 nM. Nivolumab also inhibits the interaction between PD-1 and its ligands, PD-L1 and PD-L2, with IC50 values of 2.52 and 2.59 nM, respectively. Nivolumab (1.5 ng/mL) can enhance T-cell reactivity in the presence of a T-cell receptor stimulus[1]. |
| In Vivo | Nivolumab (10 and 50 mg/kg, i.v.) is well tolerated in cynomolgus monkeys. Serum chemistry changes are limited to a reversible 28% decrease in T3 at week 13 in females treated with 50 mg/kg. T4 and TSH levels are unchanged. In males treated with 50 mg/kg, there are no changes in T3, T4, or TSH levels. Nivolumab exposure increases in an approximately dose-proportional manner between 10 and 50 mg/kg, with no substantial sex differences noted[1]. |
