Biological Activity

Description

Nivolumab (anti-PD-1) is a genetically engineered, fully human immunoglobulin (Ig) G4 monoclonal antibody directed against the negative immunoregulatory human cell surface receptor programmed death-1 (PD-1,PCD-1) with immune checkpoint inhibitory and antineoplastic activities. MW : 143.597 KD.

Targets

PD-1/PD-L1 interaction ^[2] (Cell-free assay)	PD-1/PD-L2 interaction ^[2] (Cell-free assay)
2.52 nM	2.59 nM

In vitro

The cell binding ratio of ¹²⁵I-Nivolumab and ¹²⁵I-Nivolumab-DTPA to PD-1 is 13.78 ± 2.90% and 10.22 ± 2.62%, respectively. Conjugating of DTPA does not affect targeting of Nivolumab to PD-1 in vitro.^[1]

In vivo

In SPECT images, lesions with high ^99mTc-DTPA-nivolumab uptake and relatively clear background are shown at 6 h. Thereafter, the suspected intestinal thickening in Gd-free T1WI is observed at 2 h after the addition of Gd-DTPA-nivolumab.^[1]

Protocol (Only for Reference)

Cell Assay:	Splenocytes were isolated from the spleens obtained from humanized PD-1 over-expressing mice following standard protocol. ¹²⁵I labeled Nivolumab and Nivolumab-DTPA, respectively. To perform co-culture, ¹²⁵I-Nivolumab and ¹²⁵I-Nivolumab-DTPA (0.37 MBq/µg) were added to the freshly isolated splenocytes (1×10⁶ cells) grown in 6-well plates, respectively. After incubation for 12 h at 4°C, cells were collected after rinsing three times with PBS. ¹²⁵I radioactivity was determined in a gamma counter to evaluate their binding efficiency to PD-1.
Animal Study:	Animal Models: CRC mouse models (highly expressed human PD-1 antigen) Dosages: 11.1 MBq/10 μg Administration: i.v. Reference: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8883027/

Preliminary immunotherapy drug screening using immune checkpoint inhibitors pembrolizumab and nivolumab in LGA organoids immune-enhanced with cells from a lymph node from the same patient. Mitochondrial metabolism was assessed at (c) 24 h and (d) 96 h after administration of the immunotherapy agents. Statistical significance: **p<0.05 between tumor cell-only and immune-enhanced organoids; p<0.05 between drug treatment and control of the same group.
