Pharmacology

Indication

Treatment of intermediate or high-risk myelofibrosis, including primary myelofibrosis, post-polycythemia vera (post-PV) myelofibrosis and post-essential thrombocythemia (post-ET) myelofibrosis. [Lexicomp] Myeolofibrosis is the proliferation of abnormal bone marrow stem cells which cause fibrosis (the excessive formation of connective tissue).

Associated Conditions

Pharmacodynamics

The mean half-maximal inhibitory concentration (IC50) for JAK 1 and JAK 2 are 2.8 nmol/L and 3.3 nmol/L respectively. After administration of ruxolitinib, a decrease in levels of phosphorylated STAT (marker for JAK activity) in a dose-dependent manner can be observed. Pharmacodynamic resistance has not been observed.

Mechanism of action

Ruxolitinib is a kinase inhibitor that is selective for the Janus Associated Kinases (JAK) 1 and 2. These kinases are responsible for the mediation of cytokine and growth factor signalling which in turn effect immune function and hematopoiesis. The signalling process involves signal transducers and transcription activators (STAT) which modulate gene expression. Patients with myelofibrosis have abnormal JAK1 and JAK2 activity thus ruxolitinib works to regulate this.

Target	Actions	Organism
ATyrosine-protein kinase JAK1	inhibitor	Humans
ATyrosine-protein kinase JAK2	inhibitor	Humans

Absorption

Absorption is rapid and is not affected by food. Cmax, 15 mg, healthy subject = 649 nmol/L; Tmax, 15 mg, healthy subject = 1.5 hours; Ruxolitinib does not accumulate significantly.

Volume of distribution

Terminal phase volume of distribution, 15 mg, healthy subject = 76.6 L.

Protein binding

97% protein bound, primarily to albumin.

Metabolism

Ruxolitinib is metabolized by CYP3A4. Less potent active metabolites forms as a result.

Route of elimination

Eliminated via urine (74%, <1% as unchanged drug) and feces (22%, <1% as unchanged drug).

Half life

Mean elimination half-life, 15 mg, healthy subject = 2.8 hours.

Clearance

15 mg, healthy subject = 18.7 L/h.

Toxicity

Thrombocytopenia was the dose-limiting toxicity.

Affected organisms

Humans and other mammals
