Background

Ipilimumab is a fully humanized IgG1 monoclonal antibody that blocks cytotoxic T lymphocyte antigen-4 (CTLA-4).⁵ Blocking CTLA-4 removes an inhibitory signal from reducing the activity of T lymphocytes.^1,2,5 Ipilimumab was developed by Bristol-Myers Squibb and Medarex.⁵

Ipilimumab was granted FDA approval on 25 March 2011.⁵

Pharmacology

Indication

Ipilimumab is indicated to treat unresectable or metastatic melanoma, as an adjuvant in the treatment of cutaneous melanoma, to treat microsatellite-high or mismatch repair deficient metastatic colorectal cancer, or to treat hepatocellular carcinoma.⁵ Ipilimumab with nivolumab is indicated to treat advanced renal cell carcinoma.⁵

Pharmacodynamics

Ipilimumab is a human IgG1 that binds CTLA-4, preventing 1 T-cell inhibition signal pathway.³ It has a long duration of action as it is given every 3 to 4 weeks.⁵ Patients should be counselled regarding the risk of immune-mediated adverse effects, infusion related reactions, and embryo-fetal toxicity.⁵

Mechanism of action

Cytotoxic T-lymphocyte antigen-4 (CTLA-4) is an inhibitory molecule that competes with the stimulatory CD28 for binding to B7 on antigen presenting cells.³ CTLA-4 and CD28 are both presented on the surface of T-cells.³ Ipilimumab is a human IgG1 that binds CTLA-4, preventing the inhibition of T-cell mediated immune responses to tumors.³

Absorption

C_max was 65.8µg/mL for 2-6 year olds, 70.1µg/mL for 6-<12 year olds, and 73.3µg/mL in patients 12 years and older.⁵ Data regarding the AUC and T_max of ipilumumab are not readily available.^3,5

Volume of distribution

The volume of distribution at steady-state of ipilimumab is 7.21L.³

Protein binding

Data regarding the protein binding of ipilimumab is not readily available.⁵

Metabolism

The metabolism of ipilimumab does not involve the cytochrome P450 enzyme system.^5,6 Because ipilimumab is a protein, it is expected to be degraded into small peptides and amino acids by proteolytic enzymes.⁴

Route of elimination

Data regarding the route of elimination of ipilimumab is not readily available.⁵

Half-life

Ipilimumab has a half life of 14.7 days.³

Clearance

Ipilimumab has a clearance of 15.3 mL/hr.³ Systemic clearance increases proportionally with body weight.⁶
