Pembrolizumab Chemical Properties,Uses,Production
Uses
A recombinant, single-chain, anti-CD19/anti-CD3 bispecific monoclonal antibody with potential immunostimulating and antineoplastic activities.
Mechanism of action
Pembrolizumab is a humanized monoclonal IgG4 kappa antibody directed against human cell surface PD-1 (programmed death receptor-1) on lymphocytes. The PD-1 receptor provides a critical “immune checkpoint,” which helps prevent the immune system from attacking itself. Certain tumors have a high expression of PD-L1(programmed death receptor ligand-1). Other tumor types use adaptive immune resistance, which takes the natural physiology of PD-L1 induction (protection of immune-mediated damage from infections) and adapts it to anti-tumor responses. When PD-L1 engages with PD-1, the T-cell function becomes inhibited; pembrolizumab blocks the PD-1: PDL-1 complex formation, allowing improved T-cell mediated killing[1-2].
Toxicology
Besides infusion reactions, most of the adverse events (AEs) are thought to be immune-related AEs. Grade 3–4 AEs only occur in up to 5% of patients. These immune-related AEs can occur in any organ. Because the optimal duration of treatment is undefined, pembrolizumab may be given for up to 2 y. Hence, immune-related AEs can occur late or even after cessation of treatment. To date, cases of rare life-threatening or fatal AEs have been reported after pembrolizumab, including severe skin reactions,80 and fulminant type I diabetes mellitus.81 The frequencies of AEs found in clinical trials are comparable, and are mainly observed when pembrolizumab was used at 10 mg/kg[3].
Dosage forms
Pembrolizumab is a humanized monoclonal IgG4 kappa anti-PD1 antibody. Binding of pembrolizumab to PD1 does not engage Fc receptors or activate complement, so that it is devoid of any cytotoxic activity. The 50% effective inhibitory concentration in T-cell activation assays ranges from 0.1–0.3 nM.32 It is a lyophilized powder, and reconstituted in 0.9% sodium chloride solution to a final concentration of 1–10 mg/mL for intravenous use. It is stable for 4 hours at room temperature, and 24 hours when refrigerated. It is administered as a 30-minute intravenous infusion[3].
