  1. Nivolumab • DrugbankID : DB09035 • Molecular Weight (Daltons):143597.381 • Chemical Formula: C6362H9862N1712O1995S42 • Half life :26.7 days • Description: • Nivolumab is a fully human IgG4 monoclonal antibody that acts as an immunomodulator by blocking ligand activation of programmed cell death 1 (PD-1) receptor on T cells. It is indicated for use in patients with unresectable (cannot be surgically removed) or metastatic melanoma who no longer respond to other drugs. Nivolumab is administered as an intravenous infusion over 60 minutes every 2 weeks.

  2. Indication : Nivolumab is indicated for the treatment of unresectable or metastatic melanoma for patients who no longer respond to treatment with other drugs. It is intended for use in patients who have been previously treated with ipilimumab and is used for melanoma patients after treatment with ipilimumab and a BRAF inhibitor in patients whose tumors express BRAF V600 gene mutations. Historically there have been very few effective treatments for advanced melanoma, which is why this product was approved under an FDA accelerated program to allow earlier patient access. Pharmacodynamics : Combined nivolumab (anti-PD-1) and ipilimumab (anti-CTLA-4) mediated inhibition results in enhanced T-cell function that is greater than the effects of either antibody alone, and results in improved anti-tumor responses in metastatic melanoma. In murine syngeneic tumor models, dual blockade of PD-1 and CTLA-4 resulted in increased anti-tumor activity.

  3. Mechanism of action : Nivolumab is a human immunoglobulin G4 (IgG4) monoclonal antibody that binds to the programmed cell death 1 (PD-1) receptor and selectively blocks interaction with its programmed death ligands PD-L1 and PD-L2. Upregulation of PD-1 ligands occurs in some tumors and signalling through this pathway can contribute to inhibition of active T-cell immune surveillance of tumour tissue. The inhibitory effect of PD-1 and its ligands occurs through the promotion of apoptosis in antigen specific T cells while simultaneously blocking apoptosis in suppressor T cells. Blocking PD-1 activity has been shown to lead to decreased tumour growth in mouse tumour models. Metabolism : As nivolumab is an antibody, the expected consequence of metabolism is proteolytic degradation to small peptides and individual amino acids, and receptor-mediated clearance. Absorption : The intended route of administration is intravenous, therefore bioavailability is expected to be 100%. Volume of distribution : 8.0 L Clearance : 9.5 mL/hr
